【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... 【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。 展开更多

This study was performed in five villages of Sandwip Upazila, Chittagong district with a view to identify the tree resources, utilization pattern and economic return of major fruit and timber tree species. Information collected from a total of 60 households ranging from marginal, small, medium and large categories. Number of plant species increased with the increase of homestead area. A total of 33 plant species were recorded from the homegarden, of which 19 were fruit and 14 were timber tree species. Considerable number of vegetables was also planted under the shade of the homestead trees. The investment analysis showed that average benefit-cost ratios were greater than one, net present values were positive and internal rate of returns were more than 10%. Long term investment on horticulture and timber tree species is highly profitable if species like Artocarpus heterophyllus, Cocos nucifera, Tectona grandis and Swietenia macrophylla are planted. 展开更多
