用不同浓度胶体分散剂和乳剂三十烷醇浸种,对大豆苗高,苗干重有不同程度的促进作用。其中胶体分散剂均以10~(-1)ppm浓度较为显著。乳剂对苗高有促进作用,处理间差异达到显著,但对苗干重没有促进作用。用不同浓度胶体分散剂和乳剂在大豆盛花期进行田间喷洒的试验中,使用的各种浓度均有一定的增产效应。但经方差分析,处理间差异不显著。
With different concentrations of colloidal dispersant and emulsifier triacontanol seed soaking, soybean seedling height, seedling dry weight have different degrees of promotion. Colloidal dispersions were all significant at concentrations of 10 ~ (-1) ppm. The emulsion has a promoting effect on the seedling height, and the difference between the treatments reached significant, but did not promote the dry weight of the seedlings. With different concentrations of colloidal dispersants and emulsions in the field of soybean flowering spray experiments, the use of various concentrations have a certain yield-increasing effect. However, variance analysis showed no significant difference between treatments.
