The paper discussed the effects of conservation tillage systems (reduced tillage or no till and mulching) in spring corn field on wind erosion control, water conservation, spring corn seedling emergence, yield and water use efficiency (WUE).

Advances and prospect of research on protective tillage techniques in arid areas

existing in Yanmenguan Ecological Animal Husbandry Economic Region, this paper puts forward some counter measures and suggestions of carrying out the protective tillage and improving the ecological conditions.

This paper makes comparative experiments of corn s protective tillage and traditional tillage,points out that the protective tillage possesses obvious moisture holding,impounding and yield increasing effect,and makes research and test on the BMQF-4C type corn s till-less blanketing sower.
