AbstractTo investigate the effects of water retaining agentson the growth of Elaeagnus angustifolia in arid desert regions，atapulgite-based waterretaining agent and sodiumcarboxymethylcellulose（CMC）plantfiber binder were used as experimental materials.A randomized block design was adopted， with 9 treatments： CK （control）， F1 （ 40g attapulgitebased water retaining agent mixed with soil in the planting hole）， F2 （ 80g attapulgite-based water retaining agent mixed with soil in the planting hole），F(xiàn)3 （15 g CMC plant fiber binder mixed with soil in the planting hole），F(xiàn)4 （3O g CMC plant fiber binder mixed with soil in the planting hole）， F5 （ 40g attapulgite spread at the bottom of the planting hole）， F6 （ 80g attapulgite-based water retaining agent spread at the botom of the planting hole）， F7（15 g CMC plant fiber binder spread at the bottom of the planting hole）， F8（ 30g CMC plant fiber binder spread at the bottom of the planting hole）. Survival rateandnew shoot growth of Elaeagnus angustifolia were measured，and costs were calculated.The results showed that both water retaining agents improvedsurvival rate and shoot growth，with F2 demonstrating the best performance，achieving a 94% survival rate and significant shoot growth enhancement. The costs of each treatment，from lowtohigh，were F52 respectively. In conclusion， 80g attapulgite-based water retaining agent mixed with soil in the planting hole notonlysignificantly improved survival and growth butalso maintained relatively low economic costs， making it a recommended practice for afforestation in similar arid desert regions.
