| 摘 要： | 通过对小麦3414肥效试验结果的分析，计算出小麦单位产量养分吸收量、土壤养分利用系数、肥料利用率等施肥参数，在此基础上对土壤速效养分含量与肥料利用率的相关关系进行了初步探讨，利用3414试验得到最佳施肥量，结合土壤测试值与相对产量的回归关系，建立基于土壤常规测试条件下的土壤养分丰缺指标与施肥数量指标体系。

| Abstract: | By analysis the experiment results of the 3414 fertilizer efficiency to winter wheat,the fertilization parameters,such as nutrient uptake amount per 100 kg,utilization coefficient of soil nutrients and fertilizer use efficiency were calculated.According to the preliminary research,the relationship between the available nutrient content in soil and fertilizer using rate was discussed.The optimum fertilization was obtained by 3414 experiment.Combining with the regression relationship of soil test value and relative yield,the index systems of soil nutrient sufficiency-deficiency and fertilization were built up based on the soil general testing. |
