田间对比试验和系统调查的结果表明,对稻田周边杂草采用刀刈除草方法,对捕食性天敌的损伤最小。在大面积连片稻田中间,插花种植一定面积生长期较长的其他作物,可为捕食性天敌提供“桥梁”,更有利发挥天敌的控害作用。
The results of field experiments and systematic surveys showed that the method of cutting and weeding the weeds around paddy fields had the least damage to predatory natural enemies. In a large area of contiguous paddy fields, flower planting other crops with a certain area of longer growing period can provide a “bridge” for predatory natural enemies, and more conducive to play a controlling role of natural enemies.
