据《吉林林业科技》报道,白城地区林科所夏礼煜等,在半干旱地区应用高吸水性树脂进行抗旱造林试验,取得初步效果。高吸水性树脂是近年来国外研制的一种新型高分子材料,它可以吸收与保持自身重量数百倍到数千倍的无离子水,起着降水时趿水与天旱时保水的作用。在我国,高吸水性树脂尚处于研制阶段,1982年吉林省石油化工设计院首次合成,吸水倍数可达500倍左右。试验表明,用高吸水性树脂水凝胶对苗木根系和插条进行涂层或浇灌,起到了保水
According to the report of Jilin Forestry Science and Technology, Xia Liyu, a forestry institute in Baicheng, applied preliminary experiments on drought-resistant afforestation with high water-absorbing resins in semi-arid areas. Superabsorbent resin is a new type of polymer developed abroad in recent years. It can absorb and maintain hundreds of times to thousands of times its own weight of ion-free water, play a role in water retention and drought protection when precipitation. In our country, the superabsorbent resin is still in the stage of research and development. In 1982, Jilin Petrochemical Design Institute made its first synthesis and its water absorbency up to 500 times. Experiments show that the super absorbent resin hydrogel seedlings root and cuttings for coating or watering, played a water retention
