摘　　要：试验采用磁场的不同场强，不同处理时间，在桑蚕卵胚子发育反转期（己１）时进行磁处理，结果表明：处理区５龄幼虫食下量、消化量、蚕体重均明显高于对照区．最佳处理区幼虫酶活性增强，龄期经过缩短，全茧量、茧层量、茧层率均显著高于对照区．磁场处理桑蚕卵，操作简单易行，成本低，便于推广，有显著的经济效益和社会效益，可以认为是一种易于推广的增产措施。In this experiment,eggs of mulberry-feeding silkworm were treated with different magnetic field x time at the embryo development (revered) stage (F1). The results showed that the amount fo mulberry leaves eaten by 5 instar lay larvae, digested amount and pupa weight in magnetic field teatments were significantly higher than those in CK. Also the activities of enzymes in larvae, the weights of pupa+cocoon and cocoon aam the lates of cocoon over pupa+cocoon increased greatly in suitable magnetic treatments compared with CK.
