Abstract:

In recent years, mulch cultivation as one of the protective cultivation measures of the Upland Red Soil, used widely in agricultural production day by day. At present, the plastic film cultivation and straw mulching cultivation of dryland conservation tillage is the two main ways on red soil in south china. In this study, through analysis of different cover ways on the growth and development of cotton, red soil of dryland soil temperature, soil moisture of different changes, as well as the ratio of soil carbon and nitrogen to explore coverage under different ecological and environmental effects, therefore, for the promotion in upland red soil of appropriate measures to cover planting, provide for a theoretical basis and reference patterns.
