石河子滴灌冬小麦高产氮磷最小需求研究
Response of Winter Wheat to NP Fertilization under Drip Irrigation in Shihezi
摘要
Abstract
[Objective] In order to improve the production of winter wheat and reduce the waste of fertilizers. [Method] The yield of winter wheat were appraised by two factors test of N and P under drip irrigation in Northern Xinjiang. [Result]Major research conclusions are as follows; The yield of winter wheat increased with NP fertilization application. The correlation coefficient between grain yield and the NP application was 0.99. In the present study conditions, the binary quadratic model was more comprehensive to response to the effects of winter wheat by NP. [ Conclusion ] The demand for N and P of higher yield of winter wheat is 200 -360 kg/hm2 and 0 - 100 kg/hm2.关键词
