| 摘 要： | 以郑单958和登海601为材料,研究冀西北半干旱补罐区超高产玉米的源库特征。结果表明,登海601玉米生育期长,叶面积和叶面积指数大,叶源和茎鞘的干物质积累量大,源生产能力高;郑单958表现相对登海601较差。登海601的产量达到18 474 kg/hm2,产量构成因子的表现突出,其单位穗数为91 800穗/hm2,穗粒数为528粒/穗,千粒重为384.75 g,粒叶比达到0.23 kg/m2,源库能协调发展。郑单958单位面积穗数高,穗粒数低,群体总粒数偏低,千粒重也低,产量未突破15 000 kg/hm2。 |

| Abstract: | Zhangdan958 and Denghai601 were used as materials in order to study source-sink characteristics of super-high yield maize. The result indicated that Denghai601 have the longer growing peroid. Its leaf area index is the largest. Its dry weight of leaf- source and stalk are heavier Zhangdan958. Yield of Denghai601 is 18 474 kg/ha. Number of ears per hectare is 91 800 ears/ha. Grain number per ear is 528 grains/ear. Thousand grains weight is 384.75 g. The grain-leaf ratio of Denghai601 is 0.23 kg/mm2. All of these characteristics are worse than Denghai601. Yield of Zhangdan958 is less than 15 000 kg/ha. |
