| 摘 要： | 试验结果表明,施用聚丙烯酰胺可以加速土壤水分入渗,减少渗出量,抑制土壤水分蒸发,从而增强土壤的持水能力。6kg土壤施用0.2～0.5g聚丙烯酰胺,土壤水分入渗时间为对照的2.1％～6.1％,土壤水分渗出量为对照的3.2％～48.5％,土壤含水率比对照高2个百分点以上,并可以降低土壤密度,形成良好的疏松结构。

| Abstract: | It is shown by the results of tests that applying polyacrylamide can speed up the infiltration of soil, reduce the amount of oozing, control evaporation and strengthen the capability of soil moisture keeping. 6 kg soil applies 0.2-0.5 g polyacrylamide,the infiltration time 2.1% -6.1 % of the checked one, the amount of oozing 3. 2% -48. 5% of the checked one and soil moisture content more than 2% higher than that of the checked data. Thus, it can reduce the soil density and form a porous structure. |
