The subsequent yield was obviously higher than other sowing processes.The conclusion confirmed the optimal sowing stage of maize in Linxia Prefecture to go after profits and avoid disadvantages,providing sufficient and scientific foundations for the stable and high yield of maize in the location.关键词
