Abstract

Abstract: Stalk cover changed not only the conditions out of soil, such as solar radiation, air temperature, air humidity and wind velocity, but also soil granule structure and water supply in soil. As result, it improved microclimatic conditions and mitigated soil moisture fluctuation in cropland. Because soil evaporation was reduced obviously in the earlier stage of crop growth, available water was increased during flourishing stage of crops.So water use efficiency was increased.

Key words: Stalk cover, Stalk cover, Water conservation, Review
