| Abstract: | Photosynthesis and matter production are the core of crops yield formation. The experiment analyzed rational high-yielding population structure through nutrient consumption、energy utilization and economic efficiency of different population structures. The experimental cultivars was provided with two kinds of heavy-ear and many-grain cultivars. The results indicated in the middle or high level fertilizer of wheat fields in Jinzhong late-maturing winter wheat region, high yield、quality and efficiency can be gained though decreasing sowing density (low or common density ) and utilizing heavy-grain cultivars of high photosynthetic efficiency. |
