| 摘 要： | 利用数学模型研究了肥料N、P、K对糙米蛋白质含量的影响，分析了单因素效应，双因素效应、边际效应。得出三因素对糙米蛋白质含量的贡献率大小依次为N1．9744、P2O5 1．339、K2O1．2285；N和P互作明显，高N、高P有利于蛋白质含量的提高。 |

| Abstract: | The effect of N,P and K on protein content of rice has been studied with mathematical models.Single factor effect,double factor effect and marginal factor effect have been analysed.It is concluded that the contribution of the three factors on protein content of brown rice is N 1.974 4 ,P 2O 5 1.339 2,K 2O 1 228 5.The mutual effect of N and P is obvious,and high level of N and P is beneficial to high protein content of rice. |
