蜂药在蜜蜂疾病防控中起到重要作用,使用不当也导致蜂产品质量问题.本文分析了中国、美国、欧盟、日本、澳大利亚等主要养蜂地区的蜂药类别、登记使用现状、残留限量等,同时指出我国面临着蜂药基础研究滞后、研发能力薄弱、蜂药乱用、滥用现象严重,登记蜂药种类偏少等问题,并从加强蜂药安全使用的宣传培训、蜂药基础性研究、绿色蜂药研制等方面提出应对策略,为推动蜂业高质量发展提供参考.
Previous studies have mainly focused on changes in soil physical and chemical properties to evaluate the reclamation of sodic soils using flue gas desulfurization (FGD) gypsum. However, information on the effects of this reclamation method on microbial-ba
许多养蜂人把蜂场打理得井井有条,走进蜂场,整整齐齐的蜂箱,不仅只是方便管理,还讲究造型,给人以美感.有摆成品字形,呈梯形阵势;有摆成圆弧形,像张开的纸扇;有一字排开,整齐划一.打开蜂群看看,所有群势大致相同,所有蜂王都是同期培育的,巢内摆放的蜂框数也相差不大.在生产初期是上5下8,或上5下6,蜂数大体相等,连蜂箱的使用时间也是同一时期.这样均等的群势,管理操作基本相同,蜂场管理效率高,节约时间,降低成本.
The upper earshoots with higher superiority usually have higher yield potential and higher efficiency. To determine the key period for the asynchronous differentiation of superior and inferior earshoots and how hormones are involved in this process, a two
Cotton (Gossypium hirsutum L.) is a globally important crop that is often damaged by pests and diseases. Current cotton pests and diseases management is dependent on chemical pesticides. Although chemical pesticides are usually effective, long-term applic
Nitrogen (N) deep placement has been found to reduce N leaching and increase N use efficiency in paddy fields. However, relatively little is known how bacterial consortia, especially abundant and rare taxa, respond to N deep placement, which is critical f
C-type lectins (CTLs) are a superfamily of Ca2+-dependent carbohydrate-recognition proteins, and an important pattern recognition receptor (PRR) in insect innate immunity which can mediate humoral and cellular immunity in insects. In this study, we report
Microbes are decomposers of crop residues, and climatic factors and residue composition are known to influence microbial growth and community composition, which in turn regulate residue decomposition. However, the succession of the bacterial community dur
The Northeast Plain is the largest maize production area in China, and drip irrigation has recently been proposed to cope with the effects of frequent droughts and to improve water use efficiency (WUE). In order to develop an efficient and environmentally
蜂群一旦起盗会给蜂场带来重大损失.起盗原因有多种,主要发生在外界蜜源缺乏时,制止盗蜂应以预防为主,辅以止盗措施,才能有效避免损失.rn一、预防盗蜂入侵rn1.外部防护rn把蜂箱缝隙糊严,盗蜂无法入侵.缺蜜季节缩小巢门,只能1～2只蜂出入即可.
