摘要
本文通过大蚕塑料薄膜覆盖育与常规大蚕通育对比试验,得出采用大蚕塑料薄膜覆盖育能提供低温多湿环境,减少桑叶失水,保持桑叶新鲜,提高蚕儿食下量、消化量,促进蚕儿生长发育,从而达到缩短龄期经过时间,提高全茧量、茧层量、茧层率,增加经济效益的目的。
We did some experiments of sericulture under plastic film,and compared their results with conventional method.Our results have shown that rearing grown silkworms under plastic film can keep the surroundings wet and cool,and keep the mulberry leaves fresh by reducing evaporation.Therefore,silkworms can eat and digest more mulberry leaves,and grow more quickly.As a result,the length of growth can be shortened,and the number of perfect cocoons and the layers of silk can increase.Thus,the economic benefits go up.
