我省桑蚕生产历史悠久,但由于量少面广,分带零星,加之75%左右属于自给性生产,养蚕设备简陋,饲养技术落后,导致张种平均单产只有35斤左右。有些地方单产还不到20斤,比全国平均单产水平低30斤左右。大力推行稚蚕共育专业化,是提高我省蚕茧产量和质量的重要途径。为此,要切实抓好以下几项工作 The production of silkworm in our province has a long history. However, due to the small amount of breadth and sporadic splinters, about 75% of the silkworms belonged to subsistence production. The equipment of sericulture was poor and the technique of feeding was backward, resulting in an average yield of about 35 kg.

Efforts to promote the specialization of young silkworm cocoon, cocoon production in our province is an important way to improve the quality and quantity. To this end, we must earnestly grasp the following tasks
