通过田间试验,研究了不同类型土壤上不同钾肥用量的效应以及土壤速效钾含量与玉米最佳施肥量的关系。结果表明:在不同类型土壤上,钾肥用量与玉米产量之间存在函数相关;土壤养分测定值与施钾量之间存在着密切的直线负相关,可将其作为玉米最佳施肥量的重要科学依据。
Field experiments were conducted to study the effects of different amounts of potash fertilizer on different soil types and the relationship between the available potassium content and the optimum amount of corn fertilizer. The results showed that there was a functional correlation between the amount of potash fertilizer and the yield of maize in different types of soils. There was a close linear negative correlation between the measured values of soil nutrients and the amount of potassium applied, which could be used as the important science for the optimum fertilization rate of maize in accordance with.
