春蚕全龄分段省力化饲养技术的研究初报

Primary Report on the Laborsaving Three Stage Rearing of Spring Silkworm

根据蚕的生理特点，设计1—2龄1回育、3—4龄2回育、5龄3回育的省力化饲养新技术，经对比试验，养蚕成绩好，省工、省力、省本明显，并指出其操作技术要点。

Based on the physiological characters of silkworm,a new laborsaving rearingwas designed and tested. It included three stages,i. e.,feeding silkworm once during the lstand 2nd instars,twice during the 3rd and 4th instars and three times during the sib instars.From the comparison test,it resulted in a good rearing achievement with less labor and cost.Meanwhile,the operation techniques were pointed out.
