旱田间作模式生态经济效益研究

STUDIES ON THE ECOECONOMIC EFFICIENCY OF HIGHBENEFICIAL INTERCROPPING MODELS IN UPLAND

总结报道了１９８８～１９９２年小麦－西瓜－棉花－萝卜、小麦－西瓜－玉米－萝卜、小麦－西瓜－辣椒－萝卜、小麦－棉花（ＣＫ）等４个处理、３个重要的随机区组试验及一系列对比示范田的产量、收益和生态效应。结果表明，３种间作模式比传统模式在复种指数上提高了１倍以上；在亩产值上提高了３．２６～５．２０倍；在每亩净收益上提高了４．３７～８．２４倍；在每工作日创收上提高了２．１１～３．６９倍；在产出／投入比上提高了０．７５～１．２８倍。农田生态也有所改善。各间作模式在各方面均优于传统模式“小麦－棉花”。

A field experiment of three replications,four treatments and a series of check demonstrations conducted in 1988～1992.Those four treatments are “wheatwatermeloncottonradish”、“wheatwatermeloncornradish”、“wheatwatermelonpepperradish” and “wheatcotton(CK)”.The results indicate that the output value,the net income per Mu or per labor day,and the output/input radio of the three intercropping models were able to be increased by 3.26～5.20,4.37～8.24,2.11～3.69 and 0.75～1.28 times as compared with those of CK respectively.The field ecological environment was improved.
