摘要
文章比较了两种不同方法的推荐施肥量 ,所用数据相同。结果表明 ,在接近最高施肥量的情况下 ,不同的推荐施肥量差异很大。用回归方程法得到的推荐施肥量比用“直线上升 -稳定态”
Based on the same filed-experiment results,optimum rates of nitrogen and phosphorus (P 2O 5) recommended by second order rotatable design have been compared with those by linear-plateau method.It has been found that optimum rates of nitrogen and phosphorus recommended by the second order rotatable design were respectively 1/3 geater than those by linear-plateau method.
