为了提高滴灌冬小麦产量,降低氮磷肥料的浪费,采用两因素不完全随机设计,研究了北疆中高产田氮磷对滴灌冬小麦产量的影响。结果表明:在一定的范围内,施氮磷肥能够促进滴灌冬小麦增产,且二元二次拟合的相关系数达到了0.99。冬小麦的最高产量区间为氮水平200~360kg/hm2,磷水平为0~100kg/hm2。因此,北疆中高产田滴灌冬小麦生产中应适量施用氮肥,控施磷肥,配施锌等微量元素肥料,以保证获得高产并取得较好的经济效益。
In order to increase drip irrigation winter wheat yield and reduce the waste of nitrogen and phosphorus fertilizers, the effects of nitrogen and phosphorus fertilization on drip irrigation and winter wheat yield were studied by using two factors and incomplete random design. The results showed that within a certain range, nitrogen and phosphorus fertilization could promote the yield increase of drip irrigation and the correlation coefficient of binary quadratic fitting reached 0.99. The highest yield of winter wheat ranged from 200 to 360 kg / hm2 for nitrogen and 0 to 100 kg / hm2 for phosphorus. Therefore, the North Xinjiang high-yield drip irrigation in winter wheat production should be the appropriate application of nitrogen, phosphate fertilizer, with zinc and other trace element fertilizer to ensure high yield and achieve better economic returns.
