回归均匀布点设计和简单对比的田间试验结果表明，亩产夏玉米５５０～７００ｋｇ的最高施肥量Ｎ２２５～２３８ｋｇ／亩、Ｐ２Ｏ５８６～１１３ｋｇ／亩。农田基础产量（ｙ）与碱解氮含量（ｘ）之间呈ｙ＝－３０８．２＋７．５８ｘ（ｒ＝０．９８）线性关系。由此可预测农田夏玉米基础产量并选择相应的肥料效应方程。配施Ｋ２Ｏ５ｋｇ／亩，在砂土和二合土上可增产５．２～７．７％，淤土和砂姜黑土上施钾增产均低于５％。土壤有效锌平均含量为０．７４ｍｇ／ｋｇ，施锌效果均显著。
The results of field experiment with uniform distribution design and simple comparison show that the maximum fertilization amount of N505 ~ 23.8 kg / mu and P2O58.6 ~ 113 kg / mu per mu of summer corn is 550 ~ 700kg. The linear relationship between the basic yield of farmland (y) and the content of basic nitrogen (x) is y = -308.2 + 7.58x (r = 0.98 *). From this we can predict the summer corn base yield and choose the corresponding fertilizer effect equation. With K2O5kg / mu, yield increased 5.2-7.7% on sandy soil and koji soil, and potassium production on silt and sagojiang black soil was less than 5%. The average content of soil available zinc is 0.74mg / kg, and the effect of applying zinc is significant.
