砾石覆盖下的农田土壤环境效应:研究进展与展望
Soil environmental effects of gravel-sand mulched field:research grogress and prospects
摘要
Abstract
Gravel-sand mulching is a unique conservation tillage mode in arid areas.It has been proved that surface gravel-sand mulching could adapt well to the harsh natural environment,and bring much assistance to local agricultural development and efficiency.However,a series of negative effects were brought by the degradation of gravel-sand mulched field,which had become an obstacle to the development of local agriculture.Therefore,this research summarized the effects and related mechanisms of gravel-sand mulching on soil hydrothermal environment,soil salinity,soil organic matter,soil microorganisms and enzyme activities,as well as soil water conservation.The problems and challenges faced by gravel-sand mulched field were identified,and the directions for further development were proposed,which include(1)the comprehensive evolution mechanism of soil environment in the degradation process of gravel-sand mulched field;(2)the synergistic mechanism of gravel-soil-crop system;(3)the agricultural restoration models and sustainable development paths of degenerated gravel-sand mulched field;(4)the impact mechanism of gravel-sand mulching on local regional climate.关键词
