摘　　要：在攀枝花干热河谷地区,采用保水保墒技术进行荒山造林,用10 g保水剂+覆草措施定植苗木,造林成活率可提高到98%,用10 g保水剂+覆膜措施定植苗木,造林保存率可提高到86%.Hydrogel application and ground mulching with hays are the two key factors to promote soil moisture and simultaneously to assure survival rate in afforestation in the dry-hot valley area in Panzhihua Prefecture,Sichuan Province.Mulching with hays might significantly reduce soil evaporation and enhance the infiltration of ground water into the deep-layer of soil,The survival rate of afforestation was increased by 13% when each sapling was planted with 10 g hydrogel in the planting pit and then the hay mulching was applied.Similarly,the survival rate of afforestation was increased by 12% if the saplings were planted with 10 g hydrogel per plant and then the plastic film mulching was adopted.
