研究在不同温度梯度下保水剂的粒径和用量对土壤水分蒸发的影响.结果表明:土壤水分蒸发前期保水剂粒径小则保水效果较好,保水剂用量越高则土壤水分稳定蒸发阶段时间长.25℃时土壤水分蒸发率会出现波动现象;保水剂粒径大(0.8—2mm)时,保水剂用量小会加速土壤水分的蒸发.

This paper mainly studies the size and amount of water - retaining agent in different temperature gradient on soil moisture to evaporate under the influence. Research results show: pre -evaporation of soil moisture retention agent with a small particle size performs better, and with higher amount of insurance agent used more time is consumed in stable soil water evaporation stage. At 25 ℃ there will be fluctuation with the soil moisture evaporation rate; For large aquasorb size (0.8 ~ 2 mm), the small amount of insurance agent will speed up soil moisture evaporation.
