| 摘 要： | 对８个玉米杂交种生长发育及干物质积累动态的研究表明。登海１号和豫玉２２号对砂姜黑土具有较强的适应性，主要表现为茎秆较粗；叶面积和根系胡后期衰减辐度较小；干物质积累较多，且向雌穗转运效率高。比当地推广品种掖单１２号分别增产１７．５％和１７．３％。 |

| Abstract: | Studies on the growth and change of for matter accumulation in 8 corn hybrids indicated: Denghai No. 1 and YuYu No. 22 had better adaptability to Shajiang black soil. Its principal performances were as follows:stem diameter was thicker, leaf area and dry matter weight of roots per plant were higher in the later period of development. The dry matter were accumulated and partitioned largely in ear, too. The yield was 17. 5% and 17. 3% higher respectively than that of Yedan No. 12, the locally-popularized variety. |
