林地带状混作沙打旺对土壤理化性质的影响

Impaction to the physical and chemical properties of soil by belt-shaped mixing of A.adsurgens

林地带状混作沙打旺,可以改善土壤理化性质,增加土壤肥力,提高土壤的抗风蚀能力。但是,由于沙打旺是深根性植物,与树木根系争夺水份,使林地土壤水分亏缺,应引起注意。

It is stated the belt-shaped mixing of Astragalus adsurgens could improve the physical and chemical properties of soil,increase soilfe rtili ty,and raise the ability to resist wind erosion.However,as A.adsur- gens is a deep-rooted plant,which serambles for water with root systems of trees,that makes the forest land be short of moisture,which should be noticed.
