| 摘 要： | 采用田间试验的方法研究旱地全膜覆土穴播小麦高产施肥技术。结果表明:在全膜覆土穴播种植方式下,N、P、K平衡施肥和增施P肥有利于增加小麦干物质积累量,小麦全株干物质量随生育期的增长而增长;N、P2O5和K2O的施用量分别为180kg/hm2、180kg/hm2、90kg/hm2时,小麦产量和纯收益最高,分别达到了4631kg/hm2和8454元/hm2,明显高于其他处理;在N、K肥相同施用水平下,随着施P量的增加小麦产量呈现增加趋势,表明小麦在全膜覆土穴播栽培技术条件下,应配套实施N、P、K平衡施肥,以提高小麦产量和经济效益。

| Abstract: | Field trials were conducted to study on fertilizer application techniques for high yielding wheat on soil over all-film bunch in the Semi-arid areas.The results showed that balanced application of N,P and K fertilizers and increased application of P fertilizer could increase dry matter accumulation and whole-plant dry matter accumulation of wheat gradually increased with the growth period of wheat on soil over all-film bunch.In the case of the application of 180kg/hm2,180kg/hm2 and 90kg/hm2 of N,P2O5 and K2... |
