| 摘 要： | 采用三因子二次通用旋转设计进行田间试验,研究了氮、磷、钾肥配施对甜脆豌豆产量的影响,建立了N、P、K三因素与甜脆豌豆产量的施肥模型。对模型解析发现,3个单因子对产量的影响表现为K2O>P2O5>N。施肥模型寻优结果表明:施N 134.0~209.9kg/hm2、P2O574.7~129.96kg/hm2、K2O 75.5~150.5kg/hm2,氮、磷、钾之比为1∶0.59∶0.66时可使甜脆豌豆产量达到15.55 t/hm2以上。

| Abstract: | The field experiment in the effects of the ration of N,P,K fertilizer on yield of sweet and crisp pea was conducted by 3 factors quadratic rotation design,and the optimal mathematic model of fertilization was constructed.The effects of tested factors on the yield revealed the following order: K_2O>P_2O_5>N.Based on the fertilization model,in order to get high yield more than 15.55t/hm~2,the optimum application rate of N,P_2O_5 and K_2O should be 134.0～209.9,74.7～129.96 and 75.5～150.5kg/hm~2 respectively,and the application ratio of N,P_2O_5,K_2O should be 1∶0.59∶0.66. |
