| Abstract: | Different quantities of AS-type efficient water-retaining agent was used in plantation and the growth of master trees in experimental wood was measured continuously for 8 years. The results show that the optimum quantity of water-retaining agent used in plantation is 2.5 g each hole. It can hold the soil water in the hole over three months. This will be very critical to improve survival rate in semi-arid region. But there are not obviously effects on height and diameter growth of trees. Experiment also proves that water-retaining agent in plantation is of no side effect on later growth of trees. |
