摘要: 研究干旱地区地膜条件下,土壤生态因子对玉米产量的影响.结果表明,最佳种植模式为作物距地膜中心线21.3-33.2Cm,施纯N+P为598-743kg·ha-1,玉米产量为14492≤Y佳≤16591kg·ha-1.该种植模式有利于提高作物产量及残膜回收.

Abstract: The effect of soil ecological factors on maize yield under film-mulching condition is studiedin this paper. The results show that in arid area, the optimal planting pattern of maize is;the plant is grown at 21.3-33.3cm from the centre of film-mulching, the application rateof N and P is 598-743kg. ha-1, and the yield is 14492≤Yopt≤16591kg·ha-1. Thisplanting pattern is beneficial to the yield increment and the residual film recovery.
