摘　　要：针对当前大力普及推广的小蚕工厂化饲养技术,在饲养过程中,确定小蚕工厂化最佳饲育密度标准。2023年春蚕期,我们通过不同饲育密度对小蚕的生长发育、健康状况以及蚕茧产量、质量、经济效益的影响进行试验对比,结果表明,小蚕过密饲育或过稀饲育都会使小蚕发育缓慢、食桑经过延长,影响小蚕正常生长发育;增高小蚕期减蚕率,并影响后期蚕茧产量和蚕茧经济效益。经试验表明,可以通过大蚕期精细饲养管理,来提高熟蚕结茧率和后期的茧丝质量,降低4、5龄蚕的减蚕率、上蔟后死笼率。How to determine the optimal rearing density standard for small silkworms during the breeding process,in response to the current widely promoted technology of factory rearing of small silkworms.In the spring silkworm season of 2023,we conducted experiments to compare the effects of different feeding densities on the growth and development,health status,cocoon yield,quality,and economic benefits of small silkworms.The results showed that either dense or sparse rearing of small silkworms can slow down their development,prolong their feeding period,and affect their normal growth and development,increasing the rate of reducing silkworms during the small silkworm stage and affecting the later cocoon yield and economic benefits.Through experiments,we can improve the cocooning rate of mature silkworms and the quality of cocoon silk in the later stage by fine rearing and management during the large silkworm stage,and reduce the reduction rate of silkworms in the 4th instar and the 5th instar and the dead cage rate after mounting.
