摘　　要：本实验用家蚕夏秋用新品种夏芳、秋白原种,给予4种不同的5龄给桑处理,调查其幼虫、茧、卵的各项成绩.结果表明,两品种均以克蚁5龄给桑量59kg(克蚁全龄用桑69Kg)的各项指标最佳,说明适量给桑的各项成绩均比偏多或偏少给桑的效果优良.Four treatments of feeding amount were made for the parents of the new silkworm hybrid race Xiafangand Qiubai for summer-autumn rearing at their 5th instar stage to investigate the performance of the lar-vae, cocoons and eggs. The results showed that the optimum feeding rate at the 5th instar stage was 59 kgmulberry leaves per gram of newly-hatched larvae, its performance indicators investigated in the study be-ing superior to those of any other treatment.
