摘要
Abstract
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.关键词
