植物生长调节剂在蚕桑上的应用研究

对叶面宝、丰产素、施必丰等不同类型的植物生长调节剂在蚕桑生产上的施用效应进行了研究。经叶面喷施，结果表明：这三种植物生长调节剂喷施桑树后，均有提高桑叶中叶绿素、糖、蛋白质、脂肪含量的功能。桑叶增产幅度达到１５％～３０％。用处理后的桑叶饲蚕，可以提高蚕茧产量和丝的质量，而对幼蚕体质和茧质均无明显影响。其中施必丰效果最佳。

A Stagy on Applicaton of Three of Plant-growth Regulators in Sericultural Production

The effects Of three kinds of plant--growth regUlators Yemianbao ao, Fengchansu and Shibifeng on mulberry trees and silkworms were tested in this paper,and the results showed that treatment of mulbery trees with those regulators increase the contents of chlorophyll, sarbohydrates, proteins and fats of mulbory leaves significantly. And mulberry leaf yield increase by 15%-30%. cocoon yield and quality of the silkworms fed on the treated leaves were raised without obvious negative functions. Of the three regulators,Shibifeng was the best.
