| 摘 要： | 分析了播种期对产量及其构成因素的影响，提出适期早播利于优质中籼稻91499高产。在建立施氮量和栽插密度的产量及其构成因素效应方程的基础上，指出氮素的产量效应小于栽插密度，两栽培因子与产量均呈二次曲线关系，两因素的产量效应主要通过影响有效穗数来实现的。本试验条件下，最造施氮量和栽插密度分别为182。3kg／ha和50．6万穴／ha。

| Abstract: | The effects of Sowing time on yield and its components of 91499 were analysed, and the conclusion was drawn that early sowing had positive effects on the high-yielding of 91499. Moreover,the effects of density and nitrogenous fertilizer on the yield and its components were studied. The mathematical formulas of yield and its components with the two cultural factors have been built,the formulas showed that the effects of nitrogen on yield was less than that of density, and the two cultural factors influenced yield mainly by affecting effective panicle number. The results also showed that the optimum amount of nitrogenous fertilizer and density were1l82. 5kg/ha and 5. 06 × 105hills /ha respectively in the specific experimental condition. |
