| Abstract: | A secondary orthogonal rotational design were adopted to study the P, K and Zn fertilizer application of rice in east of Hebei rice area, we found the equation between the P-K and Zn combinations fertilizer pattern and rice yields, through mathematics model we obtained the optimum combination of these fertilizers, the optimum rates of P, K and Zn were 125.40 kg/hm2, 44.25kg/hm2 and 4,80 kg/hm2, respectively. In a word, we founded a fertilizer application model to improve cpiality and yields of rice in the rice area of east of Hebei. |
