摘　　要：以先玉335为试验材料,研究不同行距种植(70、65、60、50 cm)下玉米干物质积累与分配的动态变化规律。结果表明,不同行距处理下,干物质积累总量及各器官干物质向子粒转移量、转移率及对子粒的贡献率不同,其中,70 cm行距处理下干物质积累总量和子粒转移效率都高于其他处理,在玉米种植方式上,采取70 cm的种植行距较为合理。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 aetual agricultural production should be recommended.
