Poultry production is an activity that is engaged in by a majority of traditional small-scale farmers around the world. The percentage of participants engaged in this enterprise exceeds all those participating in other forms of domestic livestock production. Domestic fowl (“chickens”) are overwhelmingly the main species around the globe world but at least eight other species of bird are reared with regional preferences for one or the other type. A multitude of breeds or varieties are present within species which provide a genetic resource of truly inestimable value and whose genes need to be conserved for posterity. Output of live birds, meat and eggs is low in the mainly extensive or semi-intensive production systems but input costs (labour, feed and medicines) are also low. Poultry contribute to poverty alleviation, household food security, create opportunities for employment and are an asset that can be rapidly converted to income. Women and children are often the principal beneficiaries of small-scale production both as managers and owners. Housing is often rudimentary, the mainly scavenged feed is of inadequate quantity and quality and health interventions are minimal except for vaccination against the plagues of Newcastle Disease and Avian Influenza. Marketing of surplus birds or product sales is largely informal but the system is quite appropriate for the sector. Official policies relating to traditional production are often minimal. There are opportunities for improved production and thus for contributing to human welfare in training of owners in management and in improving nutrition and health of the birds.
家禽生产是世界上大多数传统小规模养殖户从事的一项活动。从事这一企业的参与者所占比例超过了从事其他形式的国内畜牧生产的所有参与者。家禽(“鸡”)是世界上绝大多数的主要种类,但至少有八种其他鸟类是根据地区偏好饲养的。物种中存在着大量的品种或变种,它们提供了真正不可估量的遗传资源,它们的基因需要为后代保存下来。在主要粗放或半集约化生产系统中,活禽、肉和蛋的产量很低,但投入成本(劳动力、饲料和药品)也很低。家禽有助于减轻贫困,保障家庭粮食安全,创造就业机会,是一种可以迅速转化为收入的资产。妇女和儿童作为管理者和所有者往往是小规模生产的主要受益者。住房往往是简陋的,主要是捡来的饲料数量和质量都不足,除了预防新城疫和禽流感的疫苗接种外,卫生干预措施很少。剩余禽鸟的销售或产品销售在很大程度上是非正式的,但该系统非常适合该部门。官方对传统生产的政策往往很少。有机会提高产量,从而在培训饲主管理和改善鸟类的营养和健康方面为人类福利作出贡献。

Tobacco growing is greatly threatened by the devastating bacterial wilt disease caused by soil-borne bacteria Ralstonia solanacearum (R. solanacearum). Balanced plant nutrition has become effective strategy for crop disease management. In this study, we firstly conducted greenhouse and field experiments to investigate the effects of Molybdenum (Mo), acting as a foliar fertilizer, on tobacco plant growth and bacterial wilt control. A susceptible variety (Yunyan 87) and a moderately resistant cultivar (Nanjiang 3) were used in this study. Under greenhouse condition, the results demonstrated that the disease incidence in the Mo-treated plants decreased to 41.7% (Yunyan 87) and 44.4% (Nanjiang 3) compared with that of non-Mo-treated plants. The control mechanisms are related to the reduced bacteria colonializations in tobacco and improvement of defense enzymes including peroxidase, catalase, superoxide dismutase, polyphenol oxidase and phenylalanine ammonialyase. Malondialdehyde levels halved after 200mg/L Mo treatment compared to the control group. The field experiment results also showed that supplements of 200mg/L Mo significantly decreased the disease incidence by 30.3% and 33.9%, respectively. Moreover, foliar application of Mo increased plant growth under both growth conditions, promoting leaf and root development. Mo was taken up by tobacco leaves, but the content decreased during the growth of plants. Mo application could provide an alternative strategy for efficient management of tobacco bacterial wilt, even in crops other than tobacco, especially in Modeficient planting regions, which would have a great impact on agriculture and favor sustainable agriculture development.
烟草种植受到由土壤传播的番茄枯萎菌(Ralstonia solanacearum)引起的毁灭性细菌性枯萎病的严重威胁。植物营养均衡已成为作物病害管理的有效策略。本研究首先通过温室和田间试验,研究了钼作为叶面肥对烟草植株生长和防治青枯病的影响。以易感品种云烟87和中抗品种南江3号为研究对象。结果表明,在温室条件下,与未施用钼的植株相比,钼处理植株的发病率分别为41.7%(云烟87)和44.4%(南江3号)。控制机制与烟草中细菌定植减少和防御酶如过氧化物酶、过氧化氢酶、超氧化物歧化酶、多酚氧化酶和苯丙氨酸氨解酶的改善有关。与对照组相比,200mg/L Mo处理后丙二醛水平减半。田间试验结果还表明,添加200mg/L钼可显著降低病害发生率,分别为30.3%和33.9%。此外,在两种生长条件下,叶面施用钼均能促进植株生长,促进叶片和根系发育。Mo被烟叶吸收,但在植株生长过程中含量逐渐减少。施用钼可以为烟草青枯病的有效治理提供一种替代策略,即使在烟草以外的作物,特别是在缺乏钼的种植区,这将对农业产生重大影响,有利于农业的可持续发展。

Vinasse Waste from Sugarcane-Based Bioethanol Production Plants Kills Moniliophthora Perniciosa, the Causative Agent of Cacao Witches' Broom Disease 以甘蔗为基础的生物乙醇生产厂的酒糟废料能杀死可可女巫扫帚病的病原体——黑霉菌

Bioethanol production based on sugarcane juice fermentation yields vinasse, a dark, dense liquid waste high in potassium. In Brazil, one of the world’s biggest bioethanol producer, vinasse is used for fertirrigation of the sugar-cane fields, replacing mineral soil amendments. Nevertheless, the production largely exceeds this application, prompting exacerbated usage, unduly long-term storage and even illegal dumping. Vinasse thus progressively became an environmental hazard, damaging soils and superficial and ground waters, adding a negative burden to a supposedly green-fuel industry. The solution resides in decreasing production yields and/or using it for yet other economically interesting applications. This work focuses on the latter. Vinasses from three bioethanol plants from Brazil were tested for their ability to contain the proliferation of Moniliophthora perniciosa, the aggressive filamentous fungus responsible for cacao Witches’ Broom Disease (WBD). This disease caused a severe economic fall-out in South American cacao producing regions, particularly seriously in Brazil. Immersing or spraying the mycelium with vinasse either kills the fungus or impedes its proliferation at varying time/dosage. Identically testing another genetically unrelated phytopathogen, showed this effect is not that of a generalized biocide/fungicide. Results suggest that vinasse could be used to contain/revert the prevalence of cacao’s WBD to manageable levels. Vinasse would thus shift from industrial waste with disposal-associated costs, to being a tool for the agronomic sustainability and revival of the South American regional cacao-dependent socio-economies.
基于甘蔗汁发酵的生物乙醇生产产生酒糟,一种富含钾的深色、致密的液体废物。在巴西,世界上最大的生物乙醇生产国之一,酒糟被用于甘蔗田的施肥,取代了矿物土壤改良剂。然而,产量大大超过了这一要求,导致使用加剧,过度长期储存,甚至非法倾倒。因此,酒渣油逐渐成为一种环境危害,破坏土壤、浅层和地下水,给本应是绿色燃料的产业增加了负面负担。解决方案在于降低产量和/或将其用于其他经济上有趣的应用。本文的研究重点是后者。对来自巴西的三种生物乙醇植物的葡萄进行了测试,测试了它们抑制导致可可丛枝病(WBD)的侵袭性丝状真菌黑霉(Moniliophthora perniciosa)增殖的能力。这种疾病在南美洲可可产区造成了严重的经济衰退,在巴西尤其严重。用酒糟浸泡或喷洒菌丝体,在不同的时间/剂量下,要么杀死真菌,要么阻碍其增殖。同样测试另一种基因无关的植物病原体,表明这种效果不是一般的杀菌剂/杀菌剂的效果。结果表明,酒糟可以用来控制/恢复可可豆WBD的流行到可控的水平。因此,葡萄渣将从具有处理相关成本的工业废物,转变为农业可持续发展和南美洲地区依赖可可的社会经济复苏的工具。

During the past few years, climate change induced by global warming had caused the appearance of extreme high temperatures worldwide, which had resulted in devastating damage to crop production. High Temperature Stress (HTS) is becoming an increasingly significant problem for agricultural production. Recent studies have elucidated the complex regulatory networks and versatile metabolites involved in HTS tolerance. Here, we provided an overview of current knowledge regarding the adverse effect of HTS on plant growth and development, the impairment of HTS on photosynthesis and membrane system, the role of carbohydrate metabolism, accumulation of osmo-protectants and secondary metabolites, the induced production of Reactive Oxygen Species (ROSs) and ROS detoxification system, and the synthesis of protective proteins like Heat Shock Proteins (HSPs) in HTS tolerance. Furthermore, the role of different phytohormones in plant response to HTS were discussed and epigenetic modifications are reported to be one of the three major signaling pathways associated with HTS response in plants, through the development of a ‘stress memory’ that is generated by hypomethylation to improve the plant’s survival under recurring HTS conditions. These physiological and molecular knowledge underlying plant response to cope with HTS will be helpful for the future directions of breeding crop tolerance to HTS using these factors or other strategies for agricultural applications.
在过去几年中,全球变暖引起的气候变化在世界范围内造成了极端高温的出现,对作物生产造成了毁灭性的破坏。高温胁迫是农业生产中日益突出的问题。最近的研究已经阐明了复杂的调控网络和多种代谢物参与HTS耐受性。本文综述了高温胁迫对植物生长发育的不利影响、高温胁迫对光合作用和膜系统的损害、碳水化合物代谢的作用、渗透保护剂和次生代谢物的积累、活性氧(ROSs)的诱导产生和活性氧解毒系统、热休克蛋白(HSPs)等保护蛋白的合成等方面的研究进展。此外,我们还讨论了不同的植物激素在植物对高温胁迫的反应中的作用,并报道了表观遗传修饰是与植物高温胁迫反应相关的三个主要信号通路之一,通过低甲基化产生的“胁迫记忆”的发展来提高植物在反复高温胁迫条件下的存活率。这些植物应对高温胁迫的生理和分子基础知识,将有助于未来利用这些因素或其他农业应用策略培育作物对高温胁迫的耐受性。

Spray drift, as a practical issue during Unmanned Aerial Vehicle (UAV) spraying, has a negative impact on the environment, and the use of air-induction nozzles or anti-drift adjuvants are the most common recommendations for reducing drift. To screen the adjuvants for favourable atomization performance and anti-drift effect, we evaluated the spray atomization performance of different adjuvants by the droplet size measurement system. From the wind tunnel results, we commented on the relationship among the atomization performance, drift distance and drift deposition, and determined the drift percentage of different nozzles and the surface tension of liquids with different adjuvants. The results showed that the addition of adjuvants would modify the distribution span S, ΦVol<150μm and the volume medium diameter D50; ΦVol<150μm and D50 of the Maifei treatment decreased and increased the most of all the treatments. There were negative correlations between the drift distance, D50 and percentage of drift amount. The adjuvants Maifei and the nozzle IDK120-015 significantly decreased the drift deposition amount. And the anti-drift effect of nozzle IDK120-015 plus Maifei was significantly stronger than that of other nozzles or adjuvants. In addition, the addition of adjuvants could significantly decrease the surface tension, especially for Maifei. These results suggest that the addition of Maifei is an effective way to reduce the spray drift for all nozzle types and lessen the surface tension. These data help to provide a theoretical basis for selecting suitable nozzles and adjuvants for plant protection UAVs.
喷雾漂移是无人机(UAV)喷洒过程中的一个实际问题,对环境有负面影响,使用空气感应喷嘴或抗漂移佐剂是减少漂移最常见的建议。为了筛选具有良好雾化性能和防漂移效果的佐剂,我们通过液滴大小测量系统评估了不同佐剂的喷雾雾化性能。根据风洞实验结果,对雾化性能、漂移距离和漂移沉积之间的关系进行了评述,并确定了不同喷嘴的漂移百分比和不同佐剂液体的表面张力。结果表明:佐剂的加入会改变其分布跨度S, ΦVol<150μm,体积介质直径D50;ΦVol<150μm,麦飞处理的D50下降和增加最多。漂移距离、D50与漂移量百分比呈负相关。麦非佐剂和IDK120-015喷嘴显著降低了漂移沉积量。IDK120-015加麦菲的抗漂效果明显强于其他喷嘴或佐剂。此外,佐剂的加入可以显著降低表面张力,特别是对麦菲。这些结果表明,麦菲的加入是一种有效的方法来减少喷雾漂移和降低表面张力的喷嘴类型。这些数据有助于为植保无人机选择合适的喷嘴和佐剂提供理论依据。

The Abscisic Acid (ABA) is an isoprenoid phytohormone, regulating various physiological processes ranging from stomatal opening to protein storage. Moreover, it provides adaptation to drought, salt and cold stresses acts also as a signaling mediator during the plant’s adaptive response to environmental conditions. In addition, numbers of transcription factors are involved in regulating the expression of ABA responsive genes by interacting with their respective cis-acting elements. ABA signal transduction initiates signal perception by ABA receptors and transfer via downstream proteins, including protein kinases and phosphatases. Hence, for improvement in plants-stress-tolerance capacity, it is necessary to understand the mechanism behind it. On this ground, this article lightens the importance and also the role of ABA signaling with regard to various stresses as well as regulation of ABA biosynthetic pathway along with the transcription factors for stress tolerance.
脱落酸(ABA)是一种类异戊二烯植物激素,调节从气孔打开到蛋白质储存等多种生理过程。此外,它提供了对干旱、盐和寒冷胁迫的适应,并在植物对环境条件的适应性反应中作为信号介质。此外,许多转录因子通过与其各自的顺式作用元件相互作用,参与调控ABA应答基因的表达。ABA信号转导启动ABA受体的信号感知,并通过下游蛋白(包括蛋白激酶和磷酸酶)进行转移。因此,为了提高植物的抗逆性,有必要了解其背后的机制。在此基础上,本文阐明了ABA信号在各种胁迫中的重要性和作用,以及ABA生物合成途径和转录因子对胁迫耐受性的调控。

Manuring with organic wastes might be an important approach for maintaining soil fertility and crop productivity. However, beneficial effects of manuring may vary depending upon the type of manure and rate of application. The present study was planned to investigate the efficiency of three different manures i.e. pressmud, farmyard manure and chicken manure applied at 2.5%, 5%, 7.5% and 10% (w/w) to affect nutrient dynamics in soil and maize (Zea mays L) under alkaline conditions. Results revealed that manuring with organic wastes markedly affected the soil properties, with highest effect in case of chicken manure. Soil nutrient concentrations improved by the use of organic manures and maximum increase was found with pressmud which was 17.83%, 37.60%, 48.33% and 55.29% in phosphorus (P) and 9.82%, 20.54%, 32.14% and 40.18% potassium (K) at 2.5%, 5%, 7.5% and 10%, respectively compared to control, while farmyard manure showed superiority for soil nitrogen (N). Soil micronutrients including copper, iron, zinc and manganese were also greatly affected in response to manuring. Nutrient concentrations of maize were also enhanced by the use of manures, with maximum increase in case of pressmud which was 66.96, 77.68, 93.75 and 113.39% in N, 72.73, 154.55, 218.18 and 336.36% P, and 19.75, 30.86, 49.38 and 72.84% K at 2.5%, 5%, 7.5% and 10% (w/w), respectively compared to control. Similar trend was found in case of other nutrients. Pressmud again showed its superiority to improve grain yield i.e. 14.85%, 22.19%, 34.02% and 58.25% by the application of 2.5%, 5%, 7.5% and 10% (w/w), respectively compared to control. In conclusion, pressmud showed supremacy over other manures in improving soil properties and nutrient dynamics in soil and maize plants with a consequential increase in grain yield. The beneficial effects of manuring increased with increasing the application rate.
利用有机废弃物施肥可能是保持土壤肥力和作物生产力的重要途径。然而,施肥的有益效果可能因肥料种类和施肥率而异。本试验旨在研究在碱性条件下,按2.5%、5%、7.5%和10% (w/w)施用压浆、农家肥和鸡粪3种肥料对土壤和玉米(Zea mays L)养分动态的影响。结果表明,有机肥对土壤性状影响显著,其中鸡粪对土壤性状影响最大。有机肥处理提高了土壤养分浓度,其中,在2.5%、5%、7.5%和10%处理下,压浆处理的磷含量分别比对照提高17.83%、37.60%、48.33%和55.29%,钾含量分别比对照提高9.82%、20.54%、32.14%和40.18%,而农家肥处理对土壤氮含量有优势,土壤微量元素铜、铁、锌和锰也受到了较大影响。施用肥料也提高了玉米的养分浓度,其中,在N、72.73、154.55、218.18和336.36% P和2.5%、5%、7.5%和10% K (w/w)处理下,压榨玉米的养分浓度分别比对照提高了66.96、77.68、93.75和113.39%,K处理的增幅最大,分别为19.75、30.86、49.38和72.84%。其他营养物质也有类似的趋势。施用2.5%、5%、7.5%和10% (w/w)的压草对籽粒产量的增产效果分别为14.85%、22.19%、34.02%和58.25%。综上所述,在改善土壤和玉米植株的土壤性质和养分动态方面,压浆优于其他肥料,从而提高了籽粒产量。施肥的有益效果随施肥量的增加而增加。

A novel type of packaging that combines food packaging materials with antimicrobial substances to control microbial surface contamination of foods to enhance product microbial safety and to extend shelf-life is attracting interest in the packaging industry. In agreement with the current trend of giving value to natural and renewable resources, the use of natural antimicrobial compounds, particularly in food and biomedical applications, becomes very frequent. The direct addition of natural compounds to food is the most common method of application, even if numerous efforts have been made to find alternative solutions to the aim of avoiding undesirable inactivation. Dipping, spraying, and coating treatment of food with active solutions are currently applied to product prior to packaging as valid options.
一种将食品包装材料与抗菌物质相结合以控制食品表面微生物污染以提高产品微生物安全性和延长保质期的新型包装引起了包装行业的兴趣。与当前赋予自然和可再生资源价值的趋势一致,天然抗菌化合物的使用,特别是在食品和生物医学应用方面的使用变得非常频繁。直接将天然化合物添加到食品中是最常见的应用方法,即使已经做出了许多努力来寻找替代解决方案,以避免不必要的失活。目前,在产品包装前使用活性溶液进行浸渍、喷涂和涂层处理是一种有效的选择。
