We analysed the timing of pesticide treatments for eventual analysis of temporal environmental risks associated with pesticide use in field vegetable crops. At the same time, we investigated whether farmers followed the Integrated Pest Management (IPM) instructions. The data cover chemical plant protection in field vegetable farms in southwestern Finland in 2009–2019. The timing of treatments, made with different pesticides in the weeks following sowing, corresponded with the known phenology of different pests of carrot, swede and fresh pea. The same was true for the carrot fly, the pea moth and the second generation of the cabbage root fly when phenological flight time models using historical data were used to predict the timing of treatments. We conclude that farmers acted in accordance with the principles of IPM when practising chemical control. For those species that lacked phenological predictive models in the study years, the degree days for the observed timing of treatments can be used as a starting point if such models are developed in the future. Our results can be used as a long-term baseline in future surveys on the changes in pesticide use and their risks regarding the studied crops.
我们分析了农药处理的时间,以最终分析与田间蔬菜作物中农药使用相关的时间环境风险。同时,我们调查了农民是否遵循害虫综合治理(IPM)的指示。该数据涵盖了2009-2019年芬兰西南部大田蔬菜农场的化学植物保护。在播种后的几周内使用不同的农药进行处理的时间与胡萝卜、瑞典和新鲜豌豆不同害虫的已知物候相对应。当使用历史数据的物候飞行时间模型来预测处理时间时,胡萝卜蝇、豌豆蛾和第二代白菜根蝇的情况也是如此。我们得出结论,农民在实施化学防治时遵循IPM原则。对于研究年份中缺乏物候预测模型的物种,如果将来开发物候预测模型,可以将观测到的处理时间的度数作为起点。我们的结果可以作为未来调查农药使用变化及其对所研究作物的风险的长期基线。

The large-scale import of soybean products into the EU decreases the self-sufficiency of livestock production. The fractionation of grassland forage crops presents an opportunity to locally produce protein-rich feed for monogastrics. Two promising fractionation methods, twin-screw press juicing and leaf stripping, were evaluated in parallel in field experiments established in Norway and Sweden to compare the nutrient composition and yield of the resulting biorefined and residual fractions. The clearest delineation between the methods was in the ash-free neutral detergent fibre (aNDFom) concentration, with juicing producing a biorefined fraction with a lower aNDFom than leaf stripping. Variability in the allocation of crude protein (CP) and biomass to the biorefined fractions occurred in both methods between cuts and locations and is likely due to differing stand characteristics and inconsistency in machine functionality. Additional work is needed to understand how characteristics such as stand density, botanical composition, and plant phenological stage impact each fractionation method’s ability to allocate protein, fibre, and biomass into the resulting fractions. Future studies should focus particularly on determining standardised settings for leaf stripping machinery based on a range of stand characteristics to ensure consistency in the yield and nutrient composition of the resulting fractions.
欧盟大规模进口大豆产品降低了畜牧业生产的自给自足。草原饲料作物的分种为在当地生产富含蛋白质的饲料提供了机会。在挪威和瑞典建立的田间试验中,对两种很有前途的分离方法——双螺旋榨汁和叶片剥离进行了平行评估,以比较所得生物精制馏分和残留馏分的营养成分和产量。两种方法之间最明显的区别是无灰中性洗涤纤维(andform)的浓度,榨汁产生的生物精制部分的andform低于叶片剥离。在两种方法中,粗蛋白质(CP)和生物量分配到生物精炼部分的差异发生在切割和位置之间,可能是由于不同的林分特征和机器功能的不一致。还需要进一步的工作来了解林分密度、植物组成和植物物候阶段等特征如何影响每种分馏方法将蛋白质、纤维和生物量分配到所得分馏物中的能力。未来的研究应特别侧重于根据一系列林分特征确定剥叶机械的标准化设置,以确保所得馏分的产量和营养成分的一致性。

Adapting agriculture to climate change is essential for sustainable food production. However, the development of suitable adaptation mechanisms requires a clear understanding of the plant-climate interaction. The number of growing degree days (GDD) is a good proxy for understanding plant-climate interrelationship and farm productivity. Here, using a 2-year experiment of barley-sweet corn double cropping (DC) system and 20-year climate and yield data, we found that barley and sweet corn GDD and productivity were strongly related to changes in climate patterns. Furthermore, we found a positive effect of the barley-sweet corn DC system on farm productivity (18.5 and 5.6 tonnes. ha−1 for DC and single cropping respectively) and return on investment (1.8; 1.4 as benefit:cost ratios for DC and single cropping system respectively). Altogether the results of this study suggest that the winter barley-sweet corn double cropping system is a potential strategy to boost farm productivity as well as an adaptation mechanism to be considered for the changing climate in the study region.
使农业适应气候变化对可持续粮食生产至关重要。然而,建立合适的适应机制需要对植物与气候的相互作用有一个清晰的认识。生长度日数(GDD)是了解植物-气候相互关系和农业生产力的一个很好的指标。利用2年的大麦-甜玉米双季制试验和20年的气候和产量数据,我们发现大麦和甜玉米的gdp和生产力与气候模式的变化密切相关。此外,我们发现大麦-甜玉米直流系统对农场生产力(18.5和5.6吨)有积极影响。直作和单作分别为ha−1)和投资回报率(1.8;1.4为效益:分别为直作和单作的成本比)。综上所述,本研究结果表明,冬大麦-甜玉米双熟制度是提高农业生产力的潜在策略,也是研究区域气候变化的一种适应机制。

Building food system resilience enables the system to buffer, adapt and transform in response to changes. Identification of key variables of resilience support actors and policymakers managing the food systems. The objective of this study was to identify the most important variables to assess food system resilience and actors with the best opportunities to take responsibility for preparing for disruptions. We operationalised the key variables of resilience in the Finnish food system and evaluated them using a Delphi expert method. We produced a framework for food system resilience, including three indispensable interacting levels of action and good practices within each supporting resilience building. In the prioritisation of key variables, diversity in production, versatile cooperation between actors based on trust, independence of external inputs, system understanding, and renewable domestic energy were considered the most important. Research and administration play a key role in producing information and implementing actions targeted especially at agriculture, where actions are expected to be the most efficient and impactful. In the whole food system, increasing transparency would help create trust and thus promote co-creation of sustainable practices. Platforms to obtain information about future risks and for co-creating solutions for building food system resilience are needed.
建立粮食系统复原力使该系统能够缓冲、适应和转变以应对变化。确定恢复力的关键变量支持行为者和政策制定者管理粮食系统。本研究的目的是确定评估粮食系统恢复力的最重要变量,以及有最佳机会承担责任为中断做准备的行动者。我们对芬兰食品系统中弹性的关键变量进行了操作,并使用德尔菲专家方法对其进行了评估。我们制定了粮食系统复原力框架,包括三个不可或缺的相互作用层面的行动和每个层面支持复原力建设的良好做法。在确定关键变量的优先顺序时,生产的多样性、参与者之间基于信任的全面合作、外部投入的独立性、系统理解和国内可再生能源被认为是最重要的。研究和行政管理在提供信息和执行特别针对农业的行动方面发挥关键作用,农业方面的行动预计将是最有效和最有影响力的。在整个食品系统中,提高透明度将有助于建立信任,从而促进可持续实践的共同创造。需要有平台来获取有关未来风险的信息,并为建立粮食系统抵御力共同制定解决方案。

ABSTRACT Biochar (BC) is a soil fertility enhancer, regarded as a potential carbon sequester and nutrient leaching preventer. Various studies have shown better phosphorus (P) availability with adding biochar. However, limited reporting is available on absorption–desorption behaviour of added P and dose optimisation of biochar. Rice straw biochar (RSB) and acacia biochar (ACB), prepared by slow pyrolysis at optimised temperature and pyrolysis time, were incubated at different rates (0, 5, and 10 g kg−1) in loamy sand and clay loam soils to study P sorption compared to the unamended control. The data was observed to be best fitted into Langmuir adsorption isotherm for P adsorption. The effects on maximum P adsorption, bonding energy, and adsorption rate constants were lower in loamy sand compared to clay loam soil. The values of maximum P desorption (Dm) and desorption rate constant (Kd) decreased with the application of biochar. A linear regression equation optimised the amount of P addition for soil amendments. For the soil with inherent P content, rice biochar was the best option (5 g kg−1), while for soils lacking in P, ACB is optimised at 5 g kg−1 with external P input of 1 mg P kg−1 of test soil. This data can be recommended to the farmers as a best practice for the P addition, along with managing farm wastes as biochars to enhance nutrient availability.

What must be considered in winter strawberry production under LEDs in Iceland? 在冰岛,在led下的冬季草莓生产必须考虑什么?

ABSTRACT Supplementary lighting is essential to maintain year-round production in Iceland due to the extremely low natural light level in winter. In this research, the effects of high-pressure vapour sodium lamps (HPS) are compared to light emitting diodes (LED), both with similar photosynthetic photon flux density (PPFD). Strawberries (Fragaria x ananassa cv. ‘Sonata' and cv. ‘Magnum') were grown either under HPS lights or LEDs and 16°C/8°C (day/night). However, in the second winter, the day temperature was increased to 19°C under LEDs. The results showed that under the same temperature set points, the development of the flowers and the harvest was delayed by two weeks under LEDs due to a lower leaf, substrate and air temperature. However, when temperature set points were adapted, no delay under LEDs was observed. LEDs did not lead to higher yield, but to a higher energy use efficiency, while light use efficiency behaved contrary. Economic calculations clearly demonstrate that it is not justified to switch from HPS lights to LEDs. Instead, it is rather recommended to emphasise a high-yielding variety like Sonata in winter-growing of strawberries.

Economic calculations clearly demonstrate that it is not justified to switch from HPS lights to LEDs. Instead, it is rather recommended to emphasise a high-yielding variety like Sonata in winter-growing of strawberries.","PeriodicalId":40817,"journal":{"name":"Acta Agriculturae Scandinavica Section B-Soil and Plant Science","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90171110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT Oregano essential oil (EO) is known as one of the EOs with the highest biological activity on target plant species. In this study, the inhibitory effects of different doses of oregano (Origanum onites L.) EO on the germination and seedling growth of some wheat cultivars and some problem weed species in wheat fields was investigated. For this purpose, both laboratory and pot experiments were carried out. Oregano EO obtained by steam distillation method and component analysis was made via GS/MS. Germination tests and pot experiments were carried out under controlled laboratory and greenhouse conditions. In the study, five wheat varieties, four for bread and one for durum, and five different weed species were used. The effects of different doses of oregano EO on the germination rate, viable plant rate, seedling length, and biomass of test plants were analyzed. According to the results, it was observed that oregano EO showed bioactivity on all species and cultivars included in the experiment. In terms of all parameters, it was concluded that wheat varieties showed higher resistance to oregano EO than weed species. These results show that oregano EO can be used to control some weed species that are a problem in wheat. GRAPHICAL ABSTRACT
