农业生态管护措施与实践效果
|
Abstract:
有机管理模式下，采取保护农田边界植物与人工建设生态花带、施用沼肥进行生态化管理、病虫草害生态防控等措施，提高了农田非作物生境植物物种多样性和地上有益生物多样性，土壤线虫多样性结构得到优化。常规管理模式下，筛选出6种功能植物：矢车菊、紫花苜蓿、油菜、汤阴北艾、硫华菊、春黄菊，创建出一种小麦玉米农田天敌植物支持系统：紫花苜蓿 + 油菜 + 矢车菊天敌植物支持系统，建成了一种瓢虫和食蚜蝇周年栖息环境与迁移路径。
Under the organic management mode, some measures were taken, such as protecting the border plants of farmland, constructing ecological flower belt artificially, applying biogas fertilizer for eco-logical management, ecological control of diseases, pests and weeds, etc. , the plant species diversity and beneficial aboveground biodiversity were improved, and the diversity structure of soil nema-todes was optimized. Six functional plants, cornflower, alfalfa, rape, Wormwood in soup, pyrethroid, chamomile, a plant support system for natural enemies of wheat and maize was established, which was composed of alfalfa, rape and cornflower.
