【摘要】 本试验结果表明:稚蚕试验区使用有孔塑料薄膜覆盖育,在低温的春蚕期和晚秋期,与对照区无孔塑料薄膜覆盖育相比,两者的饲养成绩没多大差别。但在高温多湿的夏、秋蚕期,试验区的生命力和茧质都比对照区有所提高,其中夏蚕期幼虫生命率提高20.22% ,虫蛹生命率净高43.57% ,收茧量提高了55.56% 。更多还原

【Abstract】 The test results showed that there were not much difference between using holed and un-holed plastic film-covered rearing to the young silkworm at the lower temperature in spring season, but at the high temperature and humidity in summer and early autumn rearing season ,their difference was obvious, as compared with check plot, the survival rate of the experiment plot rose 20.22 %, survival rate of larva-pupa rose 43.57 %, the yield of cocoons rose 55.56 %.更多还原
