自1988年至1990年,黑龙江垦区对豆丰素进行了上百点次的小区、大区试验和几千公顷的大面积示范,绝大多数表现增产,经济效益显著。现将豆丰素的作用机理和使用注意事项介绍如下。一、豆丰素作用机理豆丰素是一种新型植物生长调节剂,是苯甲酸类物质,对双子叶植物有抑制生长作用,使其细胞壁硬化,细胞变短,同时刺激了乙烯的产生,而乙烯具抑制效应和促早熟效应。因此,大豆喷洒豆丰素后,抑制了营养生长,促进了生殖生长,起到了 From 1988 to 1990, Heilongjiang reclamation area carried out hundreds of plots of plots, large area experiments and thousands of hectares of large-scale demonstration of the abundance of beans, the vast majority of the performance of yield increase, significant economic benefits. Now the mechanism of bean abundance and the use of precautions described below. First, the mechanism of bean abundance of bean leptin is a new plant growth regulator, is a benzoic acid substances, the growth inhibition of dicotyledons, making the cell wall hardening, shortening cells, while stimulating the production of ethylene, The ethylene with inhibitory effect and promote early maturity effect. Therefore, soy bean sprouting beans, inhibited the vegetative growth and promote reproductive growth, played
