摘 要: | 通过采用三元二次通用旋转回归设计,对济麦20号优质专用小麦氮磷钾肥料不同用量产量效应的试验研究,产量≥7500kg/hm2的最佳施用尿素量为424.5~522.0kg/hm2、过磷酸钙为328.5~396.0kg/hm2、氯化钾为259.5~342.0kg/hm2。氮磷、氮钾、磷钾间交互作用显著,肥效相互促进。

Abstract: | This paper uses the rotational quadratic regression design to test the effects of nitrogen,phosphorus and potassium of wheat Jimai 20 yield.For the target yield over 7 500kg/hm2,the most desirable amount of urea,single superphosphate,Kalii Chloridum shall respectively be 424.5~522.0,328.5~396.0,and 259.5~342.0kg/hm2.The nitrogen, phosphorus and potassium pres ent apparent correlations,and the effects reinforce on an interactive basis. |
