发布时间：2021-07-27 21:26

　　Double-maize cropping system is an effective option for coping with climate change in the North China Plain.However, the effects of changes in climate on the growth and yield of maize in the two seasons are poorly understood.Forty-six cultivars of maize with different requirements for growing degree days（GDD）, categorized as high（H）, medium（M） or low（L）, and three cultivar combinations for two seasons as LH（using JD27 and DMY1 from category L in the first season; and YD629 and XD22 from category...
