秦巴山区是全国坡耕地比例最高的地区之一,水土流失十分严重。针对当地的坡耕地水土流失问题,结合当地中药产业,选取了乔木类、灌木类、草本类共6种药用植物作为植物篱物种,通过对土坎土壤营养成分、土壤理化性状及对梯地小气候的影响三个方面的测定及分析,探求其在秦巴山区水土流失防治中的生态效益。结果表明:一、植物篱成活率高,能控制耕作面的营养成分流失,改良土壤的理化性质;二、植物篱能改善其梯地内的小气候,有利于作物产量提高。
Qinba Mountain is one of the areas with the highest proportion of sloping arable land in the country, with serious soil erosion. According to the problem of soil and water loss in sloping arable land in our country, six kinds of medicinal plants, including arbors, shrubs and herbs, were selected as the hedgerows in combination with the local traditional Chinese medicine industry. By analyzing soil nutrient composition, soil physical and chemical properties, Microclimate impact of three aspects of determination and analysis to explore their ecological benefits in the prevention and control of soil erosion in the Qinling Mountains. The results showed that: (1) The hedgerows had high survival rate, which could control the loss of nutrients in the tillage surface and improve the physical and chemical properties of the soil; (2) The hedgerows could improve the microclimate in the tillage areas and improve the crop yield.
