绿肥害虫发生与防控研究现状与发展趋势

绿肥作物不仅能够提供地肥、改善土壤结构,而且还可以提供优质饲料,对我国农牧业生产安全具有重要意义,也是我国实现化肥减量、保持农业绿色发展的重要途径之一。我国绿肥种质资源丰富,绿肥害虫种类较多,但有关绿肥害虫研究的基础目前还较为薄弱,一些主要绿肥作物以及绿肥与主栽作物不同配置模式下害虫的发生种类与发生规律尚不清楚,相应的监测与防控技术缺乏。本文在系统分析国内外文献的基础上,结合国家绿肥现代农业产业技术体系的研究进展,综述了目前国内外主要绿肥作物上害虫发生的种类与规律、绿肥害虫的风险评估、不同绿肥-主作物种植模式下害虫发生规律与防控研究的现状。针对国内外绿肥害虫防控研究的现状及存在的问题,结合我国农业产业结构的调整,提出了今后绿肥害虫防控研究的主要方向。

Current status and development trends in the occurrence andcontrol of insect pests in green manure crops

Green manure crops can not only provide soil fertilizer and improve soil structure, but also provide high-quality feedstuff, which is of great significance to the safety of agricultural and animal husbandry production in China. It is also one of the important ways to reduce chemical fertilizer and maintain the green development of agriculture in China. Although the germplasm resources of green manure are rich and many kinds of insect pests occurred in green manure crops, research foundation of green manure pests in China is relatively weak at present. Occurrence and regularity of pests in the main green manure crops were not clear and the corresponding monitoring and pest management were absent. Based on the systematic analysis of domestic and foreign literatures and the research progresses in the industrial technology system of modern agriculture, this paper summarized the species and occurrence regularity of the main pests on green manure crops, the risk assessment, and the current situation of pest occurrence and control under different green manure-main crop planting patterns. In view of the situation and existing problems in the research of green manure pest control, combined with the adjustment of agricultural industrial structure in China, we put forward the main direction in the research of green manure pest control in the future.
