Globally, the aquaculture industry is one of the fastest-growing sectors in food production. To modulate the health and growth conditions of aquaculture species, probiotic feed supplements, additives, and immunostimulants of microbial origin have been used. Yeasts are becoming increasingly significant in meeting the nutritional requirements of aquaculture species, with Saccharomyces cerevisiae being the most extensively studied. Several other potential non-conventional Ascomycetous yeasts, such as Debaryomyces hansenii, Yarrowia lipolytica, Candida spp., Wickerhamomyces spp., Kluyveromyces spp., Blastobotrys adeninivorans, and Metschnikowia spp., are emerging as lucrative alternatives. Products such as β-glucans, mannan oligosaccharides, pigments, and nucleotides derived from them are also gaining popularity for enhancing the overall health and performance of aquaculture species. These lesser-explored yeast genera are utilized as probiotics, feed additives, nutritional supplements, or immunostimulants in the aquaculture industry. They help improve growth performance, antioxidant activity, and hematological parameters of aquaculture species. When included in diets, they can enhance immunity, digestion, and disease resistance against various pathogens affecting aquaculture yields. Some also serve as protein sources or enhance pigment production. Strategies such as using low-cost substrates, optimizing process parameters, metabolic engineering, and genetic manipulation of these yeasts are crucial for their sustainable application in aquaculture. This review summarizes the effects of non-conventional Ascomycetous yeasts in improving the overall well-being of various aquaculture species.
在全球范围内,水产养殖业是粮食生产中增长最快的部门之一。为了调节水产养殖物种的健康和生长条件,益生菌饲料补充剂、添加剂和微生物来源的免疫刺激剂已被使用。酵母在满足水产养殖物种的营养需求方面变得越来越重要,其中酿酒酵母是研究最广泛的。其他几种潜在的非传统子囊菌,如汉塞德巴氏菌、多脂耶氏菌、念珠菌、威克氏菌、克卢维菌、腺芽孢菌和Metschnikowia等,正在成为有利可图的替代品。β-葡聚糖、甘露聚糖低聚糖、色素和由其衍生的核苷酸等产品也因提高水产养殖物种的整体健康和生产性能而越来越受欢迎。这些较少探索的酵母属被用作益生菌、饲料添加剂、营养补充剂或水产养殖业的免疫刺激剂。它们有助于提高水产养殖品种的生长性能、抗氧化活性和血液参数。当添加到饲料中时,它们可以增强免疫力、消化能力和对影响水产养殖产量的各种病原体的抗病能力。有些还可以作为蛋白质来源或促进色素的产生。使用低成本底物、优化工艺参数、代谢工程和基因操作等策略对这些酵母在水产养殖中的可持续应用至关重要。本文综述了非传统子囊菌在改善各种水产养殖物种整体健康方面的作用。

This study investigated the immunomodulatory role of dietary vitamin D3 (VD3) in hybrid yellow catfish under high-density culture (HDC). A 2 × 3 factorial design was applied with two stocking densities and three VD3 levels (0, 1120, 14900 IU/kg). HDC significantly increased mortality, oxidative stress, lipid peroxidation, and liver Fe2+ accumulation, exhibiting ferroptosis-related features. VD3 supplementation alleviated these effects by reducing lipid peroxidation, modulating antioxidant enzymes, and activating the Keap1–Nrf2 pathway. It also upregulated gpx4 and regulated iron/lipid metabolism, thereby improving iron homeostasis and mitigating ferroptosis. Notably, VD3 downregulated slc40a1 under HDC, suggesting that its regulatory mechanism is context dependent. Within the tested conditions, 1120 IU/kg VD3 showed more pronounced protective effects against oxidative damage and ferroptosis. By contrast, under HDC, 14 900 IU/kg tended to act as an additional stressor. These findings provide new insights into the context-dependent role of VD3 in alleviating high-density stress and sustaining antioxidant balance in fish.
本试验研究了饲料中维生素D3 (VD3)对高密度培养杂交黄颡鱼的免疫调节作用。采用2 × 3因子设计,采用2种饲养密度和3个VD3水平(0、1120、14900 IU/kg)。HDC显著增加死亡率、氧化应激、脂质过氧化和肝脏Fe2+积累,表现出铁中毒的相关特征。补充VD3可以通过减少脂质过氧化、调节抗氧化酶和激活Keap1-Nrf2途径来减轻这些影响。它还上调gpx4和调节铁/脂质代谢,从而改善铁稳态和减轻铁下垂。值得注意的是,VD3在HDC下下调了slc40a1,这表明其调控机制与环境有关。在试验条件下,1120 IU/kg VD3对氧化损伤和铁下垂的保护作用更为明显。相比之下,在HDC条件下,14 900 IU/kg倾向于作为附加应激源。这些发现为VD3在减轻鱼类高密度应激和维持抗氧化平衡中的环境依赖性作用提供了新的见解。

Traditional Chinese medicine has long regarded flaxseed as a natural remedy for constipation. However, the efficacy or mechanism of flaxseed plant milk (FPM), a functional beverage derived from flaxseed, in alleviating constipation has not yet been clearly established. In this study, network pharmacology was combined with in vivo experiments to evaluate the anti-constipation activity of FPM on water restriction-induced constipation mouse model. Compared with the model group, administration of FPM (100 mg/kg and 200 mg/kg) significantly shortened the time to first black stool excretion, increased number of fecal pellets and water content of fecal pellets, and improved Small Intestinal Transit Rate (p < 0.05). Histological analysis revealed that FPM (200 mg/kg) preserved colonic epithelial integrity, reduced lamina propria damage, and restored goblet cell populations. Serum biochemical assays showed that FPM decreased vasoactive intestinal peptide (VIP) levels and increased 5-hydroxytryptamine (5-HT) concentrations. Network pharmacology identified 214 overlapping targets between flaxseed bioactive compounds and constipation-related genes, with key hub targets including TP53, CASP3, TNF, and IL6. KEGG pathway enrichment suggested that the PI3K/AKT signaling pathway may serve as a central regulatory axis. Western blot further confirmed that p-PI3K and p-AKT protein levels in the colon were reduced in constipated mice, whereas FPM administration markedly restored their expression, indicating activation of the PI3K/AKT pathway. Overall, these findings demonstrate that FPM alleviates constipation by improving stool characteristics, enhancing intestinal motility, and maintaining mucosal integrity, potentially via modulation of the PI3K/AKT pathway. This study provides new insights into the gastrointestinal benefits of flaxseed-derived functional foods and supports their development as dietary supplements for intestinal health.
传统中医一直认为亚麻籽是治疗便秘的天然药物。然而,亚麻籽植物乳(flaxseed plant milk, FPM)作为一种从亚麻籽中提取的功能性饮料,其缓解便秘的功效或机制尚未明确。本研究采用网络药理学与体内实验相结合的方法,评价FPM对限水便秘小鼠模型的抗便秘活性。与模型组比较,FPM (100 mg/kg和200 mg/kg)可显著缩短大鼠第一次黑便排出时间,增加粪球数量和粪球含水量,提高小肠转运率(p < 0.05)。组织学分析显示,FPM (200 mg/kg)可保持结肠上皮的完整性,减少固有层损伤,恢复杯状细胞群。血清生化分析显示,FPM降低了血管活性肠肽(VIP)水平,升高了5-羟色胺(5-HT)浓度。网络药理学鉴定了214个亚麻籽生物活性化合物与便秘相关基因之间的重叠靶点,其中关键的枢纽靶点包括TP53、CASP3、TNF和IL6。KEGG通路的富集表明PI3K/AKT信号通路可能是中心调控轴。Western blot进一步证实便秘小鼠结肠中p-PI3K和p-AKT蛋白水平降低,而FPM显著恢复了它们的表达,表明PI3K/AKT通路被激活。总的来说,这些发现表明,FPM通过改善大便特征、增强肠道蠕动和维持粘膜完整性来缓解便秘,可能是通过调节PI3K/AKT通路。本研究为亚麻籽衍生功能食品对胃肠道的益处提供了新的见解,并支持其作为肠道健康膳食补充剂的发展。

Oxygen depletion and sulphide formation, resulting from the accumulation of organic waste, are common challenges in shrimp ponds that could result in complete harvest failure. The stage at which these circumstances occur during the shrimp growth period remains elusive, yet, knowledge of the timing of oxygen depletion and sulphide formation is essential to enable remediating actions. Here, we used an experimental shrimp pond model at different stages in the shrimp growth period to determine when oxygen depletion and sulphide production occur. Microscale depth measurements of oxygen and H2S were determined using microelectrodes to visualize their profiles at different depths of the water-sediment interface and the sediment. We evaluated the potential of different molybdate concentrations at different stages to determine the optimal conditions to suppress H2S formation. Oxygen depletion and sulphide production took place in the middle of the shrimp growth cycle in the simulated model of waste accumulation. The addition of molybdate was only effective in the early stages of the onset of oxygen depletion and H2S formation, and residual molybdate was required to ensure a continuous suppression of sulphide production. However, oxygen depletion could not be prevented and reintroduction of oxygen did not occur when molybdate was added. In conclusion, molybdate appeared to be an effective strategy to suppress H2S formation at the onset of its production in a shrimp pond bottom model.
由于有机废物的积累而导致的氧气消耗和硫化物的形成是虾池中常见的挑战,可能导致完全的收获失败。这些情况在虾的生长期发生的阶段仍然难以捉摸,然而,了解氧气消耗和硫化物形成的时间对于采取补救行动至关重要。在这里,我们使用了一个实验虾池模型,在虾的生长期间的不同阶段,以确定何时发生耗氧和硫化物产生。在水-沉积物界面和沉积物的不同深度处,利用微电极对氧和H2S进行了微尺度深度测量。我们评估了不同阶段不同钼酸盐浓度的潜力,以确定抑制H2S形成的最佳条件。在废物积累模拟模型中,氧气消耗和硫化物产生发生在虾生长周期的中期。钼酸盐的添加仅在氧耗尽和H2S形成的早期阶段有效,并且需要残余的钼酸盐来确保持续抑制硫化物的产生。然而,当添加钼酸盐时,不能防止氧的耗尽,并且不会发生氧的重新引入。综上所述,在虾池底部模型中,钼酸盐似乎是一种有效的抑制H2S形成的策略。

This study provides a comprehensive review of the potential sources, occurrence, and impacts of antibiotics in aquaponics, along with suggested alternatives and mitigation measures to address contamination. Despite the standard prohibition against using antibiotics in aquaponics, their presence and the occurrence of antibiotic resistance genes (ARGs) remain concerning due to misuse and secondary contamination from various sources. Antibiotics can enter the aquaponic environment through various sources, such as hospital discharges, wastewater treatment facilities, and other feed sources. Existing literature on the impacts of antibiotics and ARGs in aquaponics is limited. When antibiotics enter the system, they can be detected in different components of aquaponics such as water, sediment, fish bodies, and plant roots, increasing the likelihood of developing antibiotic resistance. The emergence of ARGs could mainly occur through horizontal or vertical gene transfer pathways, while, external factors such as the presence of heavy metals and microplastics can facilitate the acquisition and proliferation of these genes. This study proposes alternative methods for disease management, enhancing systemic immunity, and future research directions. It also recommends various treatment technologies that might be integrated into aquaponic systems to mitigate the potential antibiotic contamination, aiming to prevent the issues that have arisen in traditional aquaculture, where the overuse of antibiotics has turned environments into hotspots for the proliferation of ARGs.
本研究对鱼菜共生中抗生素的潜在来源、发生和影响进行了全面综述,并提出了解决污染的替代方案和缓解措施。尽管标准禁止在鱼菜共生中使用抗生素,但由于滥用和各种来源的二次污染,抗生素耐药性基因(ARGs)的存在和发生仍然令人担忧。抗生素可以通过各种来源进入水共生环境,如医院排泄物、废水处理设施和其他饲料来源。关于抗生素和ARGs对鱼菜共生的影响的现有文献有限。当抗生素进入系统后,可以在水、沉积物、鱼体和植物根系等水培系统的不同成分中检测到抗生素,从而增加了产生抗生素耐药性的可能性。ARGs的产生主要通过水平或垂直的基因转移途径发生,而重金属和微塑料等外部因素的存在可促进这些基因的获取和增殖。本研究提出了疾病管理、增强全身免疫的替代方法和未来的研究方向。它还推荐了各种可能集成到水共生系统中的处理技术,以减轻潜在的抗生素污染,旨在防止传统水产养殖中出现的问题,在传统水产养殖中,抗生素的过度使用已使环境成为ARGs扩散的热点。

Soybean yield contests have been generating useful information regarding the cultivation of this important crop commodity. The aim of this study was to analyze environmental, management, and economic variables associated with soybean yield contest winners in Brazil. Data from eleven summer soybean harvests included grain yield, rainfall, climatic and agronomic efficiency, soil chemical and physical attributes, management strategies, and economic indicators. Two grain yield classes were evaluated: 1) high yield (4967–6839 kg ha−1) and 2) very high yield (6859–8945 kg ha−1). Enhanced soybean yield was due to adequate rainfall that led to high climatic efficiency (77 %) and high agronomic efficiency; average values ranged between 78 % (high yield class) and 86 % (very high yield class). Correction and maintenance of soil chemical and physical quality (surface and subsurface), alternative fertilization and microbial co-inoculation were notable. Winners in the very high yield class reported higher soil K+, Ca2+, and Mg2+ levels, more frequent use of dolomitic limestone, greater soil structural quality, greater use of biostimulants (via foliar spray), and higher net revenue. While high climatic efficiency was fundamental for success, intensive integration of technologies with conservation practices for better soil and crop management are necessary to maximize soybean yield and economic gains.
大豆产量竞赛提供了有关这一重要作物商品种植的有用信息。本研究的目的是分析与巴西大豆产量竞赛获胜者相关的环境、管理和经济变量。11个夏季大豆收获的数据包括粮食产量、降雨量、气候和农艺效率、土壤化学和物理属性、管理策略和经济指标。评估了两个粮食产量等级:1)高产(4967-6839 kg ha - 1)和2)非常高产(6859-8945 kg ha - 1)。大豆产量的提高是由于充足的降雨带来了高气候效率(77%)和高农艺效率;平均值在78%(高产类)和86%(极高产类)之间。土壤化学和物理质量(表层和地下)的矫正和维持、替代施肥和微生物共接种效果显著。高产作物的土壤K+、Ca2+和Mg2+含量较高,使用白云岩石灰岩的频率更高,土壤结构质量更高,使用生物刺激素(通过叶面喷雾)的频率更高,净收入更高。虽然气候效率高是成功的基础,但为了最大限度地提高大豆产量和经济收益,必须将技术与保护措施紧密结合起来,以更好地管理土壤和作物。

Winners in the very high yield class reported higher soil K<sup>+</sup>, Ca<sup>2+</sup>, and Mg<sup>2+</sup> levels, more frequent use of dolomitic limestone, greater soil structural quality, greater use of biostimulants (via foliar spray), and higher net revenue. While high climatic efficiency was fundamental for success, intensive integration of technologies with conservation practices for better soil and crop management are necessary to maximize soybean yield and economic gains.</div></div>","PeriodicalId":34095,"journal":{"name":"Oil Crop Science","volume":"10 4","pages":"Pages 294-302"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145885806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Advances in high-throughput phenotyping and genomics have accelerated our comprehension of plant functional differentiation. Nevertheless, efficiently phenotyping long-lived tree breeding populations and studying their dynamic response to field conditions remains a challenge, hindering genetic dissection and selective breeding efforts. This study refined and employed a newly developed high-efficiency unmanned aerial vehicle (UAV) imaging system to assess the temporal response of a slash pine (Pinus elliottii) breeding population in field conditions quantitatively over 2 years, identifying six strongly interrelated dynamic growth traits. In a genome-wide association study, 34 trait-associated loci explained between 1.1 % and –14.2 % of temporal phenotypic variation. These genes and regulatory loci influence signal reception, transduction, and transcriptional regulation networks in dynamic growth, impacting metabolic pathways such as cell membrane assembly, cell wall degradation, and cell differentiation. The enhanced UAV imaging system facilitates comprehensive analysis of dynamic growth response in trees, aiding in the discovery of informative alleles to unravel the genetic basis of complex phenotypic variation in conifers.
高通量表型和基因组学的进步加速了我们对植物功能分化的理解。然而,高效地分型长寿树木育种群体和研究它们对田间条件的动态响应仍然是一个挑战,这阻碍了遗传解剖和选择性育种的努力。本研究利用新开发的高效无人机(UAV)成像系统,对2年多的野外条件下湿地松(Pinus elliottii)繁殖群体的时间响应进行了定量评估,确定了6个密切相关的动态生长性状。在一项全基因组关联研究中,34个性状相关位点解释了1.1%至- 14.2%的时间表型变异。这些基因和调控位点影响动态生长中的信号接收、转导和转录调控网络,影响细胞膜组装、细胞壁降解和细胞分化等代谢途径。增强的无人机成像系统有助于全面分析树木的动态生长响应,有助于发现信息等位基因,揭示针叶树复杂表型变异的遗传基础。

Root mold proliferation presents a significant challenge in the industrial production of hydroponic barley seedlings. The small size, inconspicuous coloration, and indiscernible image of early mold regions pose new demands on detection accuracy. This study constructed a dataset of root mold in barley seedlings throughout their growth cycle and proposed the YOLOv8n-DDS detection model to integrate a lightweight detection model into a three-dimensional cyclic cultivation system. The model incorporates the dynamic sample (DySample) operator, combines deformable ConvNets v2 (DCNv2) with C2f, and reconstructs the detection head using seam carving (SEAM) technology, which enhances its capability to extract multi-scale, minute features of early-stage root mold in barley. To improve the model’s performance on edge-embedded devices, this study employed layer-wise adaptive magnitude pruning and channel-wise knowledge distillation methods, thereby significantly reducing the model’s parameter count and computational load. The pruned and distilled model was subsequently deployed on the Jetson Nano platform for validation. Results indicate that the YOLOv8n-DDS model outperformed the baseline model in terms of precision, recall, and mAP50 by 2.4 %, 5.6 %, and 2.2 %, respectively. The parameter count was reduced by 23.8 %, and the computational complexity (Giga floating-point operators per second) was optimized by 14.8 %. Additionally, the detection latency on resource-constrained embedded devices was further reduced by 25.8 % with TensorRT acceleration. The proposed root mold detection model is lightweight and contributes to the intelligent and technological integration of the industrial production process for high-quality barley seedling forage.
根霉菌增殖是水培大麦幼苗工业化生产中的一个重大挑战。模具早期区域的体积小、颜色不明显、图像难以识别等特点对检测精度提出了新的要求。本研究构建了大麦幼苗整个生长周期的根霉菌数据集,提出了YOLOv8n-DDS检测模型,将轻量化检测模型集成到三维循环栽培系统中。该模型结合动态样本算子(DySample),结合变形卷积神经网络v2 (DCNv2)和C2f算法,利用缝雕刻(seam)技术重构检测头,增强了提取大麦早期根霉多尺度、微小特征的能力。为了提高模型在边缘嵌入式设备上的性能,本研究采用了分层自适应幅度修剪和信道知识升华方法,从而显著减少了模型的参数计数和计算负荷。随后将修剪和提炼的模型部署在Jetson Nano平台上进行验证。结果表明,YOLOv8n-DDS模型在准确率、召回率和mAP50方面分别优于基线模型2.4%、5.6%和2.2%。参数数量减少了23.8%,计算复杂度(每秒千兆浮点运算)优化了14.8%。此外,在资源受限的嵌入式设备上,通过TensorRT加速,检测延迟进一步降低了25.8%。提出的根霉菌检测模型重量轻,有助于高品质大麦苗木饲料工业生产过程的智能化和技术化。

The increasing prevalence of multiple adulteration in olive oil affects product authenticity and market integrity. Therefore, it is necessary to develop advanced methods to detect the multiple adulteration. In this study, a portable Raman spectrometer was employed to address this issue, with adulterant mixtures using a D-optimal mixture design to ensure representative samples. The results showed that principal component analysis (PCA) was unable to distinguish authentic olive oils from adulterated ones, whereas partial least squares-discriminant analysis (PLS-DA) successfully differentiated the two groups. These findings demonstrated the technical feasibility of combining Raman spectroscopy with PLS-DA to detect multiple adulteration in olive oil, offering a promising method for portable, rapid authentication to counter increasingly sophisticated fraud in the edible oil industry.
橄榄油多重掺假现象日益普遍,影响了产品的真实性和市场的完整性。因此,有必要开发先进的检测多重掺假的方法。在本研究中,采用便携式拉曼光谱仪解决这一问题,掺假混合物采用d -最优混合设计,以确保样品具有代表性。结果表明,主成分分析(PCA)无法区分正品橄榄油和掺假橄榄油,而偏最小二乘判别分析(PLS-DA)成功区分了两者。这些发现证明了将拉曼光谱与PLS-DA相结合检测橄榄油中多种掺假的技术可行性,为应对食用油行业日益复杂的欺诈行为提供了一种便携式、快速的认证方法。

In the pursuit of enhancing agricultural forecasting in Pakistan, this research integrates remote sensing indices and climatic variables through advanced machine learning algorithms. By meticulously examining ten model combinations within different wheat season scenarios, the study employs nonlinear models, such as Random Forest (RF) and Support Vector Machines (SVM), and linear models, like Least Absolute Shrinkage and Selection Operator (LASSO) and Ridge. This research aims to predict wheat yield in Pakistan by integrating five remote sensing indices, including the Green Normalized Difference Vegetation Index (GNDVI), Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), Soil Adjusted Vegetation Index (SAVI), Atmospherically Resistant Vegetation Index (ARVI) with five climatic variables: Maximum Temperature (Tmax), Minimum Temperature (Tmin), Rainfall (R), Soil Moisture (SM), and Windspeed (WS) alongside the drought index and standardized Precipitation Evapotranspiration Index (SPEI). Ten model combinations were created within two wheat season scenarios: Full Seasonal Mean Scenario 1 (FSM) (SC1) and Peak Seasonal Mean Scenario 2 (PSM) (SC2). Two nonlinear ML algorithms, RF and SVM, and two linear models, LASSO and Ridge, were employed in both scenarios. Results indicated that in SC1, the RF model combination (GNDVI + SPEI + WS + SM) outperformed other models (R2 = 0.75, RMSE = 2.40, MAE = 1.98). Similarly, in SC2, the RF regression surpassed SVM, with the model combination (GNDVI + SPEI + WS + SM) demonstrating the highest performance, achieving R2 = 0.78, RMSE = 2.25, and MAE = 1.88, followed by (NDVI + Tmax + Tmin + PPT + PET + WS + SM; R2 = 0.75). The linear LASSO model also performed similarly to RF, achieving R2 = 0.74–0.69 in both scenarios. The findings advocate for utilizing SC2 for yield prediction in ML models. Overall, this study underscores the significance and potential of ML methodologies in timely crop yield prediction across various crop growth stages, thereby establishing a robust foundation for ensuring regional food security.
为了提高巴基斯坦的农业预报能力,本研究通过先进的机器学习算法将遥感指数和气候变量相结合。通过仔细检查不同小麦季节情景下的10种模型组合,该研究采用非线性模型,如随机森林(RF)和支持向量机(SVM),以及线性模型,如最小绝对收缩和选择算子(LASSO)和Ridge。利用绿色归一化植被指数(GNDVI)、归一化植被指数(NDVI)、增强植被指数(EVI)、土壤调整植被指数(SAVI)、大气抗性植被指数(ARVI)等5个遥感指标,结合5个气候变量对巴基斯坦小麦产量进行预测。最高温度(Tmax)、最低温度(Tmin)、降雨量(R)、土壤湿度(SM)和风速(WS)以及干旱指数和标准化降水蒸散指数(SPEI)。在两个小麦季节情景中创建了10个模型组合:全季节平均情景1 (FSM) (SC1)和高峰季节平均情景2 (PSM) (SC2)。两种场景均采用了两种非线性ML算法RF和SVM,以及两种线性模型LASSO和Ridge。结果表明,在SC1中,RF模型组合(GNDVI + SPEI + WS + SM)优于其他模型(R2 = 0.75, RMSE = 2.40, MAE = 1.98)。同样,在SC2中,RF回归优于SVM,其中模型组合(GNDVI + SPEI + WS + SM)表现最好,R2 = 0.78, RMSE = 2.25, MAE = 1.88,其次是(NDVI + Tmax + Tmin + PPT + PET + WS + SM; R2 = 0.75)。线性LASSO模型的表现也与RF相似,在两种情况下均达到R2 = 0.74-0.69。研究结果提倡在ML模型中使用SC2进行产率预测。总体而言,本研究强调了ML方法在作物生长各个阶段及时预测作物产量方面的重要性和潜力,从而为确保区域粮食安全奠定了坚实的基础。
