Abstract:
By means of adjusting sowing dates and using plastic film,the growth performance of maize variety with different maturity was studied under different ecological conditions. The results indicated that maize LAI and root number were different under different ecological conditions, there were significant correlations between crop yield and LAI and root numbers at the flowering stage.At the same sowing date, the root number and LAI of Yedan 13 at anthesis stage were greater than Denghai No.1.The variance of maize ear and seeds were small and the ears were more uniform under suitable ecological conditions. The variety yedan13 had bigger ears and higher yield potential. Under high temperature and low light conditions. however,Yedanl3 showed high variance in ear and seeds, and the development of the ears were not uniform.
