| 摘 要： | 通过对夏玉米"3414"肥效试验结果的分析,计算出夏玉米百公斤产量养分吸收量、土壤养分利用系数、肥料利用率等施肥参数,在此基础上利用"3414试验"得到的最佳施肥量,结合土壤测试值与相对产量的回归关系,建立了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。 |
| 关 键 词： | 施肥参数 最佳施肥量 指标体系 |

| Abstract: | By analyzing experimental results of the 3414 fertilizer efficiency for summer maize,the fertilization parameters including the amount of nutrient uptake per 100 kg,utilization coefficient of soil nutrients,fertilizer use efficiency were calculated.Based on the above results,optimum amount of fertilization was obtained by 3414 experiment.Combined with regression relation of soil nutrient content and relative yield,the index system of plentiful-lack index for soil nutrients and fertilizer amount was constructed. |
| Keywords: | Fertilization parameter Optimum amount of fertilization Index system |
