黄土高原不同耕作方式对土壤理化性质及作物产量的影响
Effects of Different Tillage Methods on Soil Physical-chemical Properties and Crop Yield in Loess Plateau
摘要
Abstract
The Loess Plateau is an arid and semi-arid rain-fed agricultural area.In the past,the traditional tillage methods were the main ones.Crop straws were not returned and the arable lands were directly ploughed,which caused the top soil to expose and accelerated the mineralization of soil organic matter.Soil erosion and nutrient loss were increased,and the quality of cultivated land was declined.Therefore,conservation tillage methods have been gradually taken in this region in order to protect the environment,improve the efficiency of water and fertilizer use and achieve sustainable development of agriculture.In this paper,we analyzed the effect of different tillage methods such as subsoiling tillage,no-tillage and conventional tillage on soil physical,chemical properties and crop yield,and some theoretical guidances were provided to establish reasonable tillage methods.关键词
