| 摘 要： | 通过实验室土壤培养的方法,研究控失尿素在土壤中的养分释放情况,并分析控失尿素对土壤电导率(EC)值的影响。结果表明:普通尿素的释放率高于控失尿素,说明控失尿素比普通尿素有更长的肥效期;控失尿素的氮释放率随着控失剂含量的增加而降低;控失尿素能够提高土壤EC值。

| Abstract: | The nutrient release mechanism of loss-control urea is studied by means of soil incubation experiments,and the effect of loss-control urea on EC value of soil is analyzed.The results show that the release rate of the ordinary urea is higher than the loss-control urea,so the nutrient release time of loss-control urea is longer than the ordinary urea;The release rate of nitrogen for loss-control urea is reduced with the increasing of loss-controlled agent;The loss-control urea can improve the EC value of soil. |

| Keywords: | loss-control urea the release of nutrient electric conductivity (EC) value |
