Abstract:
S.B technology is a comprehensive production technology with seed treatment，fertilization and removing growing point.The yield-increasing effect of S.B technology was analyzed with soybean Jiyu 47 as materal.Results showed S.B seed treatment increased seed weight；S.B fertilization increased plant height，pod number and seed weight；removing growing point increased branch number and pod number，so the three individual technology all increased soybean yield significantly.The best treatment combination for the highest yield was：S.B seed treatment，S.B fertilization and removing growing point of the second compound leaf. The optimum density of S.B technology was 1.5×10-5plants per hectare.Although had obvious yield-increasing effect，removing growing point could form double-stem plants，weaken stem diameter and lodging resistance Removing growing point should be carefully used.
