【Abstract】 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 only one third of the imported product of the same quality.更多还原
