摘要
【目的】实地调研南疆三地州的粮食棉花果树间作模式,了解当地的多种间作模式及其基本情况,确定粮棉果最佳的间作模式。【方法】选取10个静态指标和2个动态指标,改进的主成分分析法对24种粮棉果间作模式的经济效益评价,并用熵值法进行复核评价,两者的评价结果通过了Kendall-W协和系数法的一致性检验,由集成综合评价法得最终评价结果结果。【结果】果树处于不同时期,其适宜的间作模式不同,因果树类别及间作作物而异;处于盛果期时,核桃-小麦、核桃-玉米、核桃-小麦-玉米,这种核桃间作粮食作物的模式的经济效益较高,并且除了棉花单作的经济效益较高外,其他单作的经济效益都比间作低。【结论】粮棉果间作有利于提高农民的收入水平。
[Objectove] Through spot investigation in three regions of southern Xinjiang, we had a rudi- mentary knowledge of the local multiple patterns of grain - cotton - fruit intercropping. [ Method ] In order to determine the optimum intereropping mode, 10 static indexes and 2 dynamic indexes were selected to evaluate the economic benefits of 24 patterns by using the method of principal component analysis. [ Result ] The fruit trees in sapling stage, the economic benefits of almond - cotton 〉 Walnut - wheat - corn 〉 walnut - cot- ton 〉 red jujube - cotton 〉 red jujube - wheat - corn. The fruit trees in the provinces, Walnut - wheat 〉 Walnut - corn 〉 walnut - wheat - corn 〉 Ahnond - cotton 〉 Walnut - cotton 〉 almond - wheat - corn 〉 the almond trees - wheat - corn 〉 cotton 〉 almond - cotton 〉 red jujube -Wheat 〉 walnut - wheat - soy beans 〉 red jujube - wheat - green beans 〉 wheat - corn 〉 corn 〉 wheat. [ Conclusion] So, the grain - cotton - fruit intercropping was beneficial to increase the income of farmers and worth of extension
