摘要

This work systematically investigates the effects of wheat-straw/corn-stalk mulch on the e- cological environment in upland crops (winter wheat, summer corn) field from 1997 to 1998. With and without mulch soil moisture distribution, water demand, day and night variation of soil temperature, weeds control, crop yields, water and soil conservation, as well as improvement of soil texture were ex- perimentally investigated. The optimal mulch rate for both water saving and yield-increase was deter- mined.
