| 摘 要： | 对土壤保水剂（本中心实验室合成）在果园土壤的保水保墒作用及其持续作用的研究结果表明，施用土壤保水剂后，土壤水分含量第一年可提高９％以上，第二年可提高６％以上，第三年可提高４％以上；在约４５ｃｍ土层附近存在一个防止土壤水分下渗的防水层，该处土壤水分含量最高。土壤保水剂的保水作用是通过最大限度利用自然降雨和防止水分下渗及减少土壤水分蒸发来实现的。

| Abstract: | Soil hydrate synthesized by our laboratory used in fruit orchards in Weibei arid plain were first reported,and the preservation and sustained preservation of soil moisture in the late years was also reported. The principles of the preservation of soil moisture were analyzed as:modifying the structure of soil, maximumly lowering the evaporation of the soil moisture,preventing the leakage of the water. And the factors influcenced the preservation of soil moisture:climates,soil moisture,soil temperature,value of soil pH,quantity of soil hydrate used and capacity of soil moisture preserved. It is obtained that soil moisture could rise more than 9,6% and 4% in the first,second and third experimental year respectively compared with contrary,and a water-prevented layer was formed around the depth of 45 cm in the soil that used soil hydrate. |
