| 摘 要： | 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。

| Abstract: | The filed experiment was carried out for researching the relationships between the different potassium fertilization effects,soil available potassium contents and the optimum fertilizer rates of maize on the different types of soil.The results indicated that there was a functional relation between potassium fertilizer rates and maize yields.The measured value of soil nutrients was supreme straightly negative correlation with potassium fertilizer rates,which can be the significantly scientific bases for the optimum fertilizer rates of maize on the different types of soil. |
