| 摘 要： | 根据大量田间试验和调查资料分析,作者提出烟单14号玉米生长过程中,小喇叭口期土壤中全氮、大喇叭口期土壤中速效磷的含量与产量相关密切。并据此建立了产量及构成三因素与土壤养分间的最优相关模型。

| Abstract: | Based on the analysis of numerous data of field experiments and investigation, it is suggested that the yield is controlled by the total nitrogen content in the soil during the period of small trumpet of corn growth and the amount of effective phosphorus in the soil during the period of large trumpet of corn growth. The models describing the relations of the summer corn yield and the three factors composing the yield to the nutrient in the soil are established |
