半免耕法对芒果园土壤理化性状影响的调查研究

通过对半免耕芒果园中免耕与翻耕地的调查和取样,从土壤含水量、pH值、有机质及土壤氮、磷、钾等方面进行分析比较半免耕栽培对土壤理化性状的影响.结果表明半免耕法对提高芒果园土壤蓄水性、表层有机质及全氮的积累有一定的作用,而对土壤其它理化性状的影响却未呈现出来.

Investigation on the Effects of Half-tillage Cultivation on the Physical and Chemical Properties of Mango Garden's Soil

Though the investigation and analysis of the nontilled land and tilled land in the half-tillage mango garden, the effects of the half-tillage cultivation on the physical and chemical properties of soil are comparably studied from the water content, pH value, organic content to the content of nitrogen,phospho rus, potassium. The results show that the method of half-tillage cultivation has an effect on improving the property of soil water storage, the accumulation of organic and nitrogen in the surface of soil, but has no effect on the other physical and chemical properties of soil.
