摘要 用高温与常温两种温度进行一日两回育试验。调查蚕儿生长发育及饲料效率的差异。结果 ,高温区蚕儿生长快 ,叶丝转化率高 ;常温区生长发育较高温区慢 ,与四回育相同 。 It was carried out the experiment of rearing silkworm in high temperature and normal temperature two feedings a day to study the difference of the growth and development and feed efficiency. The results showed that reared silkworm in the high temperature the larva growth was fast and the leaf-silk conversion rate was high, and reared in the normal temperature the growth was slower compared with rearing in high temperature, but the quality of cocoon was better.
