Abstract:: The experiments w ere conducted by plot test in 1997 and 1998, and pot test in 1998.Three soybean varieties, Hei jiao 92- 1526, Ha92- 3857 and Hefeng 25 w ere used. Plantg row th regulator was ZFA w hich was made in Chinese Ag ricultural Univ ersity. ZFA w asapplied by foliar spray at the following t reatments FT1( 1: 1000, 1 time) , FT2( 1: 3000, 1time) and FT3( 1: 1000, 2 times af ter 7 day s) and by coating seed ( 1: 500, 1: 250) .The result s indicated that ZFA could sig ni ficant ly reduce height of soybean plant andlength of soybean internode, and increased dry mat ter per unit leng th of internode andchlorophy ll content ov er those of the cont rol ( CK) . ZFA could increase grain number grainw eight per plant , 100 g rain w eight and yield.
