| 摘 要： | 通过油菜盆栽试验，研究了膨润土的保氮增产效果。膨润土用量在土重的0．5％范围内，随着用量增加，可明显减少氮素养分的淋溶损失，保氮能力增强，明显促进植株出苗和生长，提高作物产量。膨润土在砂质土壤上的最佳经济施用量为土壤重量的5％。

| Abstract: | Experiments with rape pot culture were carried out to investigate effects of bentenite improving soil fertilizer - conserving and increasing yields. The results suggested that with the use of bentenitc addictive along 0 - 5 %, the more addictive used, the more effect of improving soil fertilizer- conserving, the less of nireogen leaching. It could improve soil nutrient supply. It could also improve the growth of crops and increase the yeilds. The best economic usity of bentenite to sand soil was 5 % of soil gravity. |

| Keywords: | bentenite nitrogen-conserving ever-increasing yieMs nitrogen loss |
