This paper studied the application result of a new typed absorbent in the saijing black soil, The result indicated that: The new typed absorbent restraint to the growth of the early –stage cabbage vegetables, but with the moisture intimidate enhancing,absorbent protecting moisture effect exerted, the growth of the cabbage vegetables recovered very quickly, at theharvest period, cabbage vegetables yield、 water efficiency、 the soil preserve water capacity notability higher than the check by applied absorbent. The result of the deep-dress absorbent is best, the production increase rate reach to 15.5%, the water efficiency increased by 48.3%, the new typed absorbent have a good applied foreground in saving-water agriculture.
