为解决南方地区大面积风化紫砂土和新开荒的红壤土种草困难的问题,研制出复合型保水剂CP-Ⅱ.室内测试和室外应用结果表明,其保水倍率较高,稳定性好,能耐盛夏地表高温,并兼有粘结土层,促进草籽萌发生长的作用,且价格仅为同级进口产品的1/3.经应用单位在107国道20 km范围内的种草护坡试验表明,经过酷暑干旱季节,效果良好,草籽粘附于土层发芽率高达80%,不到一个月,小草群体即能覆盖土面.

In order to solve the problems of growing grass on purple soil and newly reclaimed red soil,a compound water preservation agent of CP Ⅱ was prepared.The results of lab test and field application experiment show that CP Ⅱ has a relatively high water preservation ratio.It can stand high temperature of the earth surface in summer,and glue soil and promote grass seed germination and the growth of grass seedlings.While,the cost of CP Ⅱ equals on...
