| Abstract: | The persistence of drought-resistant and water-retaining agent to wheat and poplar was studied.The results showed that the water-retaining agent could maintain and enhance the soil moisture,promoted the growth of wheat root and plant,and made the thousand grain of qualities increase 0.8～5.2 g.In the First year,the production increased 18.9%,and in the second season,it increased 8.9%.The water-retaining agent made the chest-diameter of three-year poplar increase 40%~66% compared to the control group,and the height and crown also significantly higher than that of control. |
| Keywords: | drought-resistant and water-retaining agent wheat poplar persistence |
