保护性耕作对贫瘠型黑土区土壤理化特性的影响
Effects of Conservation Cultivation on Black Soil Physic-Chemical Properties in Arid Area
摘要
Abstract
Soil physic-chemical properties were studied in arid area under two conservation cultivations (one was deep plough,flat sowing and straw-mulching,the other was deep plough and ridge forming,rootstalks and field).It was found that two conservation cultivations could increase the content of soil organic matter,raise the pH,and the straw-mulching had the greatest effects,it was also had different results due to different available nutrition.Besides,the conservation cultivations could reduce soil bulk density,increase field moisture capacity.Different conservation cultivations took important role in increasing soil fertility and improving soil physical properties.关键词
