摘　　要：试验证明，夏伐时留一适当枝条，然后在行间横伏，将梢端插地固定，伏条基部锯割伤口促进基部萌发壮芽，结合收获夏叶留下基部壮芽，再将伏条剪去，可使夏叶大幅度增产，小区试验增产８６．６４％，中试增产５１．４％；叶质也有明显改进，夏伐伏条技术简便易行，对桑树的生长无不良影响。Based on the 7 years’a new method that could result in remarkable increase ofsummer leaf output was presented by the authors.A proper branch was retained on eachtree while conducting summer pruning. Then it was bent low with its top inserted intosoil. For promoting budding at the base,it was cut slightly at the base part.The strongbuds were kept and the branch was cut off after summer leaf was harvested.Thispractice resulted in an increase of summer leaf output by 86. 64%in pot planting test.The average output increased by 51. 40%(the highest over 100%)in plot trial.Meanwhile ,leaf quality was improved remarkably. It has also been proved that there isno harmful influence to the growth of mulberry by practicing this simple method.
