| 摘 要： | 利用数学模型研究了N、P、K对水稻产量的影响,分析了单因素效应、双因素效应和边际效应,得出三要素对产量的贡献率大小依次为：N1．2081、P1．0527、K0．8499;N和P互作明显;当P处于高水平时,N的增产效果明显。说明高N、P配合适当的K是提高水稻产量的重要途径之一。

| Abstract: | The effects of N, P and K on rice yield have been studied through mathematical models. Single factor effects, double factor effects and side effects have been analysed. The results showed that the contributions of N, P and K to yield was N 1.2081>P 1.0527>K 08499. There was significant interaction between the effects of N and P. When the level of P was high,the effect of N was significant. Therefore, high yield of rice could be obtained with high levels of N and P accompanied with suitable level of K. |
