摘要
以苹果园的土壤为研究对象,研究3种土壤除草方式对土壤质量和养分的影响。结果表明:在土壤质量方面,3种处理中以压草覆盖处理能降低土壤容重,但是对pH影响不显著;在土壤养分方面,以压草覆盖处理对有机质提高显著;但是在土壤全氮、磷、钾含量上,除草剂除草处理含量最高。
Taking the soil in Malus pumila orchard as research object,the effects of three kinds of weeding methods on quality and nutrients of soil were conducted.Result shows that in terms of soil quality,grass-pressing-mulching can reduce soil bulk density and has little effect on pH among three treatments;in terms of soil nutrients,grasspressing-mulching can significantly improve the organic matter;in terms of the total N,total P &total K content of soil,the herbicide content is the maximum.
