摘要
采用三因素五水平最优回归设计,研究了钙磷锌组合对水稻产量、品质的影响和肥料的最佳组合以及水稻营养元素积累与钙磷锌组合的关系等。
The experiment was conducted by using the best pluratistic regresion design of three factors at five levels. It gave a series of studies: the effect of combined application of Ca, P, Zn to the yield and quality of rice; the optimal combination of fertilizer; the absorbing characteristics of nutritional element of rice at the tilling stage; the relationship between the accumulation of nutritional element of rice and the combined application of Ca, P, Zn in the soil.
