摘要

利用随机区组设计，研究了在始穗期叶面喷施6-苄基腺嘌呤(6-BA)、6-糠胺基嘌呤、玉米素等3种细胞分裂素类物质对地膜早作水稻防衰及产量的影响。结果表明：6-BA能较好的防止地膜早作水稻早衰，增加有效穗数、穗实粒数和粒重，增产极显著，增产达15．94％，6-糠胺基嘌呤、玉米素则防衰及增产效果不显著。

Abstract

By using block design the effect of 6-benzyladenine

6-Amine and zeatin spray on senescence prevention and yield of pellicle dry-cultivated rice during its early earning stage were studied. The results showed as follows: the early-senescence was effectively prevented and the yield was significantly increased when 6-BA used on pellicle dry-cultivated rice

the highest yield increased reached 15.94%. At the same time

the effect of 6-Amine and zeatin were not significantly.
