麦棉套种对11月作物产量及土壤养分动态变化的影响

Effects of Interplanting Wheat with Cotton on Crop Yield and Dynamic Change of Soil Nutrition Content

[目的]探讨麦棉套种对作物产量及土壤养分动态变化的影响。[方法]设计麦套春棉与单作春棉比较、麦套春棉及麦套夏棉试验,测定棉花与小麦产量,并测定试验前后土壤养分的含量。[结果]麦棉套种能够提高土壤肥力,减少化肥施用量,提高总体收益。[结论]该研究可为麦棉套种地区高产栽培提供参考。

[ Objective ] The research aimed to discuss the effects of interplanting wheat with cotton on crop yield and dynamic change of soil nutrition content. [ Method] The comparison test of interplanting wheat with spring cotton and only planting spring cotton, the interplanting wheat with spring cotton test and the interplanting wheat with summer cotton were carried out, and the yield of cotton and wheat .and soil nutri- tion content before and after test. [ Result ] The interplanting wheat with cotton can improve soil fertility, decrease the application rate of chemical fertilizer, promote the income. [ Conclusion ] The study can provide reference for high yield cultivation in areas of interplanting wheat with cotton.
