新型吸水剂在砂姜黑土甘蓝包菜上应用效果

研究了一种新型吸水剂在砂姜黑土应用效果。结果表明：新型吸水剂对生长初期甘蓝包菜生长有一定的抑制作用,但随着水分胁迫增加,吸水剂保水效果的发挥,包菜的生长很快恢复,到收获期,包菜产量,水分利用效率,土壤保水能力都显著高于对照处理。吸水剂以深施效果最好,增产率达15.5%,水分利用效率提高48.3%,供试的吸水剂在抗旱节水上有很好的应用前景。

The Effect of the New Typed Absorbent on Cabbage Vegetables in the Saijing Black Soil

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 the harvest 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.
