【摘要】 山区发展紫穗槐潜力很大,而紫穗槐林可有效截留降雨,改善土壤物理性质,增强土壤的抗剪力,防治水土流失,防止风害,改善农田小气候,使小麦增产10％以上;亩施500kg紫穗槐绿肥可使小麦增产10％～20％,玉米增产20％～30％。作者根据山东沂蒙山区8年的小流域治理实践,较全面地论述了紫穗槐的水保、经济等效益,指出在山区大力发展紫穗槐是以短养长,加速山区开发行之有效的短平快措施。更多还原

【Abstract】 Developing False Indigo forest in mountainous area has a great potentiality. False Indigo forest has the effect of intercepting precipitation efficiently,improving physical properties of soil,enhancing the shear strength of soil and preventing soil loss from taking place in the area. False Indigo forest also can control wind erosion to improve the micro - climate on the farmland and increase the wheat output by more than 10%. The output of wheat and maize per mu will increase by 10%-20% and 20%-30% respectively if 500kg of green manure of False Indigo is applied on. According to eight years’ conservation practice in Yimeng mountainous area of Shandong Province,the author discusses in detail the economic benefit and the benefit for soil and Water conservation by planting False Indigo and suggests that the development of False Indigo forest is an efficient measure to accelerate the exploitation of the mountainous area.更多还原
