本文试验用增产灵和２，３，５－三碘苯甲酸（ＴＩＢＡ）对间作大豆不同生态类型品种进行喷施。喷施增产灵后，对早熟矮杆品种各处理均表现增产，其增产幅度为０．３７％－６．７５％，施用时期以结荚期为佳；早中熟、中杆、生长较为繁茂的品种仅在开花期喷３０ｐｐｍ可增产１２．０６％；增产灵的增产作用主要是由于提高了单株叶面积、叶绿素含量、单株粒重和百粒重。喷ＴＩＢＡ后，对植株主要起降矮壮杆的作用，株高降矮０．５２－１０．７８ｃｍ，抗倒能力增强，早熟、矮杆的７５－８８－１３开花期喷施呈减产效应，而结荚期喷施可增产０．４７％－３．５％；早中熟、中杆的冬二则在开花期喷施可增产６．４２％．
In this paper, ZSP and 2,3,5-triiodobenzoic acid (TIBA) were sprayed on different ecotypes of intercropped soybean. Spraying Zabuli, the varieties of early maturing dwarf varieties showed an increase of yield, the rate of increase of 0.37% -6.75%, the application period to pod stage is better; early maturing, in the pole, the growth is more lush Of the varieties only spray 30ppm in the flowering stage can increase 12.06%; Zaibing Ling production is mainly due to increased leaf area per plant, chlorophyll content, grain weight per plant and 100 kernel weight. After sprayed with TIBA, the plants mainly played the role of reducing stubble, the plant height was reduced by 0.52-10.78cm, the ability of lodging resistance was enhanced, and the yield of 75-88-13 flowering stage of premature and short stalks was decreased. The podding spray can increase yield 0.47% -3.5%; early maturing, the pole of the winter two spraying at flowering can increase 6.42%.
