| 采用三因素二次通用旋转组合设计,在柴达木地区以春小麦甘春20号为对象研究了播种量、施氮量、施磷量与籽粒产量、蛋白质含量、蛋白质产量的相关关系。结果表明,该地区春小麦甘春20号的籽粒产量、蛋白质含量、籽粒蛋白质产量与播种量、施氮、磷量之间有极显著的相关关系。施氮量对籽粒产量、蛋白质含量、籽粒蛋白质产量影响最大,播种量次之、施磷量最小。该地区甘春20号小麦栽培因子最优组合为播种量404.5 kg/hm2、施氮量(纯氮)240 kg/hm2、施磷量(P2O5)195 kg/hm2。建议当地降低播种量,增加磷肥施用量。 |

| By using regressive experiment method of orthogonal conic substitution with three factors, the regression relationship between seed dosage and N and P applying amount and grain yield, protein content and protein yield was studied on spring wheat variety Ganchun No.20 in Chaidamu area.The result showed that there is significant regression relationship between seed dosage and N and P applying amount and the three indexes mentioned above.The significance of the effect of cultivation factors on grain yield, protein content and protein yield are in the order of: N applying amount, seed dosage and P applying quantity.The optimizing combination of cultivation factors on spring wheat variety Ganchun No.20 in this area are seed dosage (404.5 kg/hm2) , N (pure N 240 kg/hm2) and P (P2O5 195 kg/hm2) , so it is suggested that the seed dosage should be reduced and P applying quantity should be increased properly. |
