摘要：

Aiming at wheat-corn two crops one-year and through the probe experiment, this paper discussed the coupling effect of returning straw to soil and nitrogen fertilizer on the wheat colony dynamic, leaf area coefficient, chlorophyll, photosynthetic rate, water use efficiency and wheat quantity and factor of forming, etc. The results indicated that returning straw to soil increases the production more than the control by 4. 77%. The reasonable coupling of the returning straw to soil and the nitrogen fertilizer can reduce the field water consumption in the stage from sowing seeds to the jointing, with 2.94%similar to 12.04% increase of the water use efficiency.
