【摘要】 通过国际国内植物篱技术发展的回顾,认为通过研究,已初步形成了一种新型的、可供推广应用的坡耕地治理技术。植物篱技术的优点在于能有效的控制坡地的水土流失,增加作物的产量,增加经济收益,促进畜牧业的发展,在逐步形成梯地的过程中,投资较省、地力得到提高。但在该技术的推广应用上,因受地域条件差异的影响和农民对经济效益的追求使成篱作物较难选择,形成的植物篱容易破坏。我们采用农民参与选择成篱作物的方法,实践证明在一定范围内,农民能选择出风险小、经济效益较高,适合当地条件的,受群众欢迎的新型植物篱模式,能促进植物篱技术发展,明显地提高了植物篱技术推广的成功率。更多还原

【Abstract】 Through the review of the research on hedgerow cropping by international and domestic institutions,it is sure that a new protection technology on sloping farmland primarily formed for extension.Alley cropping technology can effectively control soil and water erosion,increase crop yield and economic income,improve development of animal husbandry,save fund and reduce fertility degradation under the terracing periods.But in extension stage it faces the problem of difficult selection of suitable hedgerow crops from various plans at different ecosystem,and farmers willing on increasing economic income.Another problem is that the formed hedgerows are easy to be destroyed.Farmers’participatory selection of hedgerow crops provided a new method for successfully expanding in special ecosystem.The lower-risk,higher income,suitable at local conditions,farmers accepted crops were selected as hedgerows.It can promote development of this technology and increase successful ratio on expanding.更多还原
