摘要: 采用正交二次旋转组合设计方法,进行了冀东稻区水稻的磷、钾、锌肥的配方施肥试验,建立了水稻产量与磷、钾、锌肥施用量间的回归方程,通过数学模拟筛选了磷、钾、锌肥的最佳组合方案,其方案为磷肥量125.40 kg/hm2、钾肥量为44.25kg/hm2、锌肥量为4.80 kg/hm2,为冀东稻区的水稻高产优质栽培提供了一个施肥模式。

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 mode
