摘要
本文通过选用苏云金杆菌和克螨灵两种生物农药以不同浓度的稀释液于蚯蚓饲养期间进行模拟喷淋试验,观察蚯蚓生长发育。结果表明,采用高效Bt(8000IU/mg)稀释100倍的高浓度对蚯蚓生长有干扰作用,50倍浓度影响了蚯蚓的正常生殖,稀释浓度200倍以上对蚯蚓的生长和繁殖没有影响;采用克螨灵(0.5％阿维菌素)稀释1000倍和500倍的浓度对蚯蚓生长有干扰作用,100倍浓度抑制蚯蚓生长,稀释浓度1000倍以上对蚯蚓的生长和繁殖没有影响。
Two Bio-pesticides on the growth and death of earthworm by the different concentration diluted 100 times, 50 times will affect the earthworm reproduction. The concentration diluted over 200 times will have no effect on the growth and reproduction of earthworm. Kemanling (0.5%avermecti) diluted 1000 and 500 times will effect the earthworm, 100 times will restrain the growth of earthworm. Diluted over 1000 times will have no effect on the growth and reproduction of earthworm.
