摘 要:21世纪以来,浙江蚕种业发生了较大的变化。蚕种饲养量和生产量自2008年开始以每年10%~20%的速度快速下滑。蚕种母蛾微粒子病超标淘汰率2012年至2016年超过5%,2017年后控制在1%以下,杂交率、良卵率、实用孵化率等质量指标处于全国领先水平。审定通过蚕新品种21对,特别是雄蚕种和彩色茧品种,市场推广量较大,近几年接近10万张/年。2000年开始,国有蚕种场改制,现有22家蚕种生产企业,以民营性质为主。蚕种市场与价格逐步建立了依法、有序的产销管理体制,并在全国率先创建了蚕种储备制度,向乌兹别克斯坦等“一带一路”国家出口蚕种。Significant changes have taken place in sericulture of Zhejiang Province since the 21st century.The total amount of silkworm eggs produced and used for silkworm cocoon production have been declining rapidly at a rate of 10%~20%per year since 2008.The elimination rate of unqualified eggs was over 5%due to pebrine disease exceeded the standard from 2012 to 2016,and then was controlled below 1%after 2017.The quality indicators such as hybridization rate,good egg rate and practical hatching rate were in the leading level in China.21 pairs of new silkworm varieties have been approved,especially the male-only silkworm eggs and natural color cocoon varieties.The market promotion volume is relatively large,and nearly 100000 boxes/year recently.Since 2000,the state-owned silkworm farms have been restructured.There are 22 silkworm seed production enterprises,mainly privately owned.A legal and orderly production and marketing management system was established for silkworm egg production.The silkworm seed storage system was first established in China.Silkworm eggs were exported to the countries on the one belt-one road such as Uzbekistan.
