通过对８４个按统一方案布置在全国１５个省水稻氮、磷、钾肥料试验产量离均差的统计分析，初步研究了肥料试验处理与误差的关系。结果表明，大部分施肥处理对产量离均差绝对值方差及其平均数的影响未达统计学显著水平，这些施肥处理的具有同质性，这为水稻肥料试验产量资料方差分析及无重复试验资料统计分析的可行性提供了参考依据。
Based on the statistical analysis of 84 tests on the average yield of nitrogen, phosphorus and potassium fertilizers distributed in 15 provinces based on the unified plan, the relationship between fertilizer trial treatment and error was preliminarily studied. The results showed that most of the fertilization treatments did not affect the variance of the absolute value of yield from the average and its effect on the average was not statistically significant. The fertilization treatments were of the same quality, which was an analysis of variance of yield of rice fertilizers and non-repeated test Data statistical analysis of the feasibility of providing a reference.
