摘要： 以单作棉田为对照,重点探讨了棉椒间作施肥的效应。结果表明,棉椒间作既维持了较高的棉花产量水平,又显著提高了棉田的经济效益和水分利用率,且对该地区现有可支撑水资源有明显适应性。750.0 kg/hm2K2SO4复合肥间作棉田的经济效益和水分利用率更加稳定且较高,施肥主要是进一步提高间作棉田的经济效益和水分利用率。

Abstract: This paper gives a main dicussion about the effectiveness of fertilizat ion for cotton??cluster redpepper inter??cropping by compared to single cotton fields. The f indings show that the cotton??cluster redpepper intercropping not onlymaintains the high cotton yield but also improves obviously economic profits and eff iciency of water??using and also showthe great adaptation to the present water resources of this cotton??zone. 750??0 kg/ ha K2SO4 compound fertilizer can makeeconomic profits of cotton fields and efficiency of water??using more stable and higher. The main purpose of fertilization is to improve the economic profits and efficiency of water??using of intercropping cotton fields.
