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.
