| 摘 要： | 为了解决晚播冬小麦产量不稳和品质低的问题,采用“3414”平衡施肥试验设计,以氮、磷、钾为供试因子,产量和品质为目标函数,对河北省低平原地区晚播冬小麦施肥数学模型进行了研究。根据数学模型得出最佳施肥量为:N=210.99 kg/hm2,P2O5=188.51 kg/hm2,K2O=80.31 kg/hm2,产量可达7 964.88 kg/hm2;小麦蛋白质含量达到14.85%的施肥方案为:N=265.64 kg/hm2,P2O5=197.99 kg/hm2,K2O=148.17 kg/hm2;小麦沉降值达到22.19 mL的施肥方案为:N=199.38 kg/hm2,P2O5=173.54 kg/hm2,K2O=108.33 kg/hm2。

| Abstract: | The fertilizer effect on late wheat was investigated by using the "3414" balance application design to build the mathematical model for the relationship between wheat qualities,yield and application scheme.The optimum fertilization scheme obtained from the model is 210.99 kg/hm2 urea,188.51 kg/hm2 superphosphate and 80.31 kg/hm2 potassium sulphate,and the yield could reach 7 964.88 kg/hm2.The fertilization rate for 14.85% protein content is 265.64 kg/hm2 urea,197.99 kg/hm2 superphosphate and 148.17 kg/hm2 potassium sulphate,ad that for 22.19 mL flour sedimentation value is 199.38 kg/hm2 urea,173.54 kg/hm2 superphosphate and 108.33 kg/hm2 potassium sulphate. |
