【Abstract】 Plant growth regulator(Cc) makes soybean’s height decreased,activity of root system enforced、total root length increased,dry weight of root are boosted by 18.41%-35.13%,the difference is significant Dry weight of shoot are increased by 6.58%-15.79%;Minimal multi element fertilizer (Mi) makes soybean’s height increased,leaves’area are enlarged,dry weight of shoot and root are boosted by 8.55%-13.16%、11.31%-15.30% respectively,the differences are significant;Pesticide and fungicide (Ki) make soybean’s ratio of sick plant dropped by 20-21.55 percentage points,lower density’ Ki makes soybean’s ratio of seedling increased,activity of root system enforced,other physiological properties and growth amount also are improved.High density’s Ki and Cc are disadvantagous to soybean’s seedlings.更多还原
