江苏省蚕桑生产基本状况及蚕病疫情调查分析 中文摘要
中文摘要
为了探讨蚕桑生产,掌握家蚕疫病的发生规律,对江苏省蚕桑生产的基本状
况和蚕病疫情进行了调查。结果显示:江苏省 2008 年有 万ha(1003938 亩)
桑园,537909 个农户,全年饲养蚕种 2635709 张,产茧 97484 吨,约 亿元;
蚕张种产量 37kg,平均每户的养蚕收入为 3414 元,亩桑产值 1829 元。在江苏省
已初步形成盐城市和南通市二个蚕桑生产优势特色区域,年产茧量占全省的 70%
左右,但各养蚕区的技术水平差异不明显,单位桑园面积饲养的蚕种数量不足是
亩桑产茧量低的主要原因。通过对吴江市、如东县调查结果显示:蚕农的平均年
龄为 岁,平均养蚕年数达 24 年,丝茧育户平均拥有桑田 hm,春蚕平
均每户饲养蚕种 张,每 667m2桑园平均饲养春蚕 张。春季蚕病总体发
生较少,随着养蚕次数增加发病率增加明显,秋蚕各种蚕病的发生明显增加,总
发病率达 %,高于春蚕(%);遗失蚕率大大高于发病率,遗失蚕率是比发
病率对蚕茧量影响更大的一个因素;蚕病的发生情况因地域而不同,各养蚕区的
蚕病防治的重点也不同。
