摘　　要：为了明确保水剂在干旱半干旱地区抗旱造林中的使用效果,试验对保水剂的保水性能及使用保水剂后3种造林树种植株的生长特征及根系生物量进行了测定。结果显示,保水剂能显著促进造林树种植株的生长发育,使植株的基径、树高、侧根数、侧根长、总干重、根干重等比不用保水剂的对照植株明显增加,根冠比增大。需要注意的是在使用保水剂进行造林时,要选择适宜的剂型和造林季节,这是保水剂抗旱造林的关键环节。In order to ensure the effect of super absorbent polymer in drought-resistant afforestation in arid and semi-arid region,the water retention ability of the super absorbent polymer,and the plant growth characteristics and root biomass of three kinds of afforestation trees after application of super absorbent polymer were tested.The results showed that the super absorbent polymer could significantly improve plant growth and development of afforestation tree species as plant base diameter,tree height,lateral root number,lateral root length,total dry weight,root dry weight,root-shoot ratio was obviously increased compared to control.It should be paid attention that suitable super absorbent polymer form and planting season should be chosen,as it was the key for drought-resistant afforestation with super absorbent polymer.
