摘　　要：农用土壤保水剂Guilspare在半干旱地区林业生产中应用效果表明:在半干旱地区林业生产中,在浓度为1%的条件下,使用一定量的农用土壤保水剂Guilspare能明显提高土壤蓄水保墒能力,促进树木生长;超过一定量反而降低土壤蓄水保墒能力,对树木生长不利。Testing the effectiveness of Guilspare on agricultural soil the application effect to indicate in half arid area forestry production that, In half arid area forestry production, In the density is under 1% condition, The use Guilspare guarantees the soil moisture on agricultural soil to be able obviously to enhance the soil to store water ability, the promotion arboreal growth; Exceed certain quantity to turn over and reduce soil retain water to preserve soil moisture ability, for trees growth disadvantage.
