Abstract
Four levels of 70cm,65cm,60cm and 50cm were set in the test,and Xianyu335 were used as tested materials,the effect of row spacing on the regularity of accumulation and distribution of dry matter in spring maize were studied in this paper.The results showed that the regularity of distribution of dry matter was affected by the treatment of different row spacing,which under 70 cm treatment.Amount of dry matter accumulation and transfer rate of organ to grain were both higher than other treatments.So 70 cm's row spacing of planting pattern in the actual agri-cultural production should be recommended.
