摘要
以超优66冬小麦品种为材料,采用双因素设计,对不同施氮量和施氮方式下冬小麦农艺性状和籽粒蛋白质含量进行了分析比较。试验结果表明,施氮量240kg/hm2和底施40%+拔节40%+孕穗20%的施肥方式组合为高产组合;施氮量240kg/hm2和底施40%+拔节40%+灌浆20%的施肥方式组合为高蛋白产量组合。
The experiment was conducted to study the effects of on the agronomic characters and the grain protein content of winter wheat with double factors trial design, and Winter wheat varieties Chao-You 66 as material. The results showed that the optimum combination for high yield was 240kg/hm2 nitrogen fertilizer and the method that the percentages of base fertilizers, elongation fertilizers and booting fertilizers were 40%, 40%, 20%. The optimum combination for high grain protein yield was 240kg/hm2 nitrogen fertilizer and the method that the percentages of base fertilizer, elongation fertilizer and milk fertilizer were 40%, 40%, 20%.
