Compensation effect of winter wheat grain yield reduction under straw mulching in wide-precision planting in the North China Plain

Abstract Climate change and the growing demand for food security force growers to identify ways both to improve food production and to reduce agricultural carbon emissions. Although straw mulching is known to decrease CO2 emissions, winter wheat grain yield in the North China Plain was declined unde...
