全国各蚕桑产区饲养量、产茧量及推广品种10年间的变化

The Change of Amount of Silkworm Eggs Distributed, Cocoon Yield and Popularized Varieties in 10 Years in Each Sericulture Area

2005年对全国18个省的蚕种饲养量、推广蚕品种进行了调查,2015年对相同省份进行了同样调查。分析发现,与2005年比,2015年蚕种饲养量减8.10%,产茧量减1.66%;张种产茧量有所提高6.81%;蚕区分布有所变化,广西为超级蚕区,蚕种饲养量占全国的45.97%,产茧量占全国的44.91%;四川、云南和江苏3省为重点蚕区,广东、浙江、山东、安徽、重庆、陕西、江西、湖北和河南9省为主产蚕区,湖南、山西、贵州、甘肃和新疆5个省为零星蚕区;产茧量变化,增量最多的是广西,增速最快的是云南,略高及基本持平的是贵州、广东和四川,减产较快的是江西、湖北、河南、陕西、安徽、江苏、重庆、浙江和山东。

The amount of silkworm eggs distributed, cocoon yield and popularized varieties of 18 provinces were investigated in 2005 and 2015. The result showed that the amount of silkworm eggs distributed in 2015 was 8.10% less than 2005, the cocoon yield in 2015 was 1.66% less than 2005, the cocoon yield per box of eggs in 2015 was 6.81% more than 2005. The distribution of serieulture area was changed. Guangxi province became the super serieulture area, with 45.97% amount of silkworm eggs distributed and 44.91% cocoon yield. Siehuan, Yurman and Jiangsu were key serieulture areas; Guangdong, Zhejiang, Shandong, Anhui, Chongqing, Shanxi, Jiangxi, Hubei and Henan were main serieulture areas; Hunan, Shanxi, Guizhou, Gansu and Xinjiang were sporadic serieulture areas. The cocoon yield of Guangxi was increased most quickly; the cocoon yield of Guizhou, Guangdong and Siehuan were basically not changed; the cocoon yield of other serieulture areas were all decreased.
