Abstract:

In order to determine the optimal application amount of N,P2O5,and K2O for Glycine max (Linn.) Merr. Zhexian 9,a single factor fertilizer efficiency experiment was conducted. The results showed that when the N application amount was 300 kg·hm-2,the pod yield and total yield were the highest,at 12 400 and 20 950 kg·hm-2,respectively. When the N application amount was 150-375 kg·hm-2,the pod yield showed an increasing trend with the increase of N application amount. When the application amount of P2O5 was 0,the maximum yield of pods was 12 367 kg·hm-2. However,when the application amount of P2O5 was 0-112.5 kg·hm-2,pod yield decreased with increasing P2O5 application amount. When the application amount of K2O was 75 kg·hm-2,the maximum yield of pods was 12 500 kg·hm-2. When the application amount of K2O was 75-375 kg·hm-2,the pod yield showed a decreasing trend with increasing K2O application amount. Considering pod yield as the primary indicator,this study indicates that the optimal fertilizer application amount for Glycine max (Linn.) Merr. Zhexian 9 are N 300 kg·hm-2+P2O5 0 kg·hm-2+K2O 75 kg·hm-2.
