| 摘 要： | Soybean cultivar Bei 92-28 was tested in this experiment in 2000 to study the coupling effect of water and ferilizer on soybean yield. The results showed that the effect of irrigation varied among the levels of fertilizer application,and vice versa；pods per plant ,seeds per pod. and 100-seed weight had positive correlations with soybean yield,but the degrees of correlations of different treatments were various;LAI and dry matter accumulation could be significantly increased when watered and applied fertilizer with different levels,but high fertilizer application treatment didn‘t obtain the highest yield; watering could increase the absolute absorption amount of N,P,K in seeds,but the accumulation rates were various.
