摘要
以湖桑32号桑品种为对照,于2009-2011年,对四川省凉山州不同桑树品种嘉陵20号、南叶1号、云桑2号进行了连续3年的桑叶主要生化指标与养蚕饲育效率的相关性研究。研究表明:以桑品种嘉陵20号粗蛋白含量最高,养蚕饲育效率最好;云桑2号和南叶1号桑品种的粗蛋白含量差异不大,饲育效率也较为接近,参试品种的粗蛋白含量和饲育效率明显高于对照。研究还表明,不同品种桑叶中粗蛋白的含量与养蚕的饲育效率呈明显的正相关关系。
Abstract： To understand the correlation between biochemical index of mulberry and silkworm - rearing efficiency, we studied three different mulberry varieties Jia Ling 20, Nan Ye 1 and Yun Sang 2 for three consecutive years （2009 - 2011 ） in Liangshan Yi Autonomous Prefecture of Sichuan province. We compared the results with that of Hu Sang 32. The study shows that mulberry of Jia Ling 20 has the highest content of crude protein and leads to most efficient silkworm rearing; mulberry of Yun Sang 2 and Nan Ye I have similar content of etude protein and lead to similar rearing efiqeien- cy. These three varieties have a markedly higher content of crude protein and rearing efficiency than Hu Sang 32. The study also shows that the content of crude protein is apparently and positively correlated to silkworm - rearing efficiency.
