【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。
[Abstract]:[objective] to investigate the intercropping patterns of grain, cotton and fruit trees in three prefectures of southern Xinjiang, to understand the intercropping patterns and their basic conditions, and to determine the best intercropping pattern of grain, cotton and fruit. [methods] Ten static and two dynamic indexes were selected. The improved principal component analysis method was used to evaluate the economic benefits of 24 intercropping models of grain, cotton and fruit, and the entropy method was used to evaluate the economic benefits. The results of the evaluation passed the consistency test of Kendall-W Concord coefficient method. The final evaluation results were obtained by integrated comprehensive evaluation method. [results] the suitable intercropping patterns of fruit trees were different in different periods, which varied according to fruit tree types and intercropping crops, and walnut-wheat, walnut-maize, walnut-wheat, walnut-corn, Walnut, wheat and corn, the pattern of walnut intercropping grain crops, has higher economic benefits, except cotton monoculture. The economic benefit of other monoculture is lower than that of intercropping. [conclusion] the intercropping of grain, cotton and fruit is beneficial to raise farmers' income level.
