Abstract
Trials of water and N fertilizer coupling on soybean's leaf area index,height,dry matter accumulation,pod growth and water use efficiency was carried out under field experiment and drip irrigation.Results showed that the impact of the nitrogen fertilizer on leaf area index and dry matter accumulation in soybean is greater than that of water,and their effects are positive.The effect of water and nitrogen interaction is positive too.In addition,when the application amounts of N,P and K are 108.33 kg/hm2,90 kg/hm2 and 75 kg/hm2 respectively,water use efficiency will reach maximum,i.e.0.582 kg/m3.
