摘要
通过盆栽试验和田间小区试验比较了叶施翠竹牌植物生长剂、丰收宝和三十烷醇对紫花苜蓿生长和产草量的影响。两年的试验结果表明,植物生长剂对苜蓿生长的促进作用和增产效果最显著,各茬苜蓿分枝初期叶施1:8000植物生长剂水液(操作液40～50公斤/亩),处理一次苜蓿产草量增加12.8～22.4％,处理二次(间隔10天)产量增加20.8～34.1％。1990年在天津宁河示范施用,110亩紫花苜蓿地平均每茬增产鲜草220.5公斤/亩,比对照地增产22.9～47.8％。
The effects of auxins or plant promoters of Green Bamboo, Feng Shou BaG and alkyl alcohol on the Growth and yield of alfalfa has been compared with each other through pot culture tests and field plot experiments. The results of two years' tests indicates that, the influence of auxin G B is the most remarkable one between them on the growth promoting and yield increase of alfalfa. When the leaves of alfalfa were treated once by spraying G B solution at the beginning of the branching stage of alfalfa stubbles In different years, the yield increase of alfalfa recorded 12.8～22.4％; while they were treate twice (with a 10—day interval )the yield increase marked 20.8～34.1％. In 1990, at the pilot plots of 110 mu of alfalfa, Ninghe county, Tianjin, the average yield increase noted 220.5kg/mu. The yield increase shows 22.9～47.8％ more than that of the control.
