摘要:“十三五”期间,我国茶叶功能成分提制技术特别是终端产品开发获得了长足的发展,在规模、层次、效益上都得到明显提升。文章简要阐述了近年来现代分离纯化技术在茶叶功能成分开发中的应用成果,以及茶的功能性终端产品开发的多元化、专一化、精细化发展现状,并提出了茶叶功能成分利用的未来发展趋势及建议,以期为我国茶叶深加工研究与产业发展提供参考。 关键词:茶叶深加工;功能成分利用;提制技术;终端产品;十三五
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
