白于山区生态环境脆弱,立地条件差,植被稀疏.为丰富白于山区物种多样性,改善生态环境,本研究通过将三种针叶树在白于山区进行造林试验,采用保水剂、覆膜等措施,筛选出适合三种针叶树的抗旱造林技术.结果表明:(1)樟子松(Pinus sylvestris var mongolica)、彰武松(Pinus densiflora var.zhangwuensis)和班克松(Pinus banksiana)在横山区和靖边县均能存活,存活率均在48％以上;(2)在横山区和靖边县使用保水剂2的班克松处理存活率最高,分别达68.89％和73.33％;(3)三种针叶树在靖边县存活情况均优于横山区;(4)在横山区,使用保水措施覆膜和保水剂2的樟子松生长情况显著优于CK和保水剂1处理,使用覆膜处理的彰武松显著优于其他处理,使用保水剂2的班克松生长最好;(5)在靖边县使用保水措施覆膜和保水剂2的樟子松和彰武松生长情况较优,班克松使用覆膜处理生长情况最优.三种树种均适合在白于山区栽植,且班克松适合使用保水剂2,樟子松和彰武松可选择使用保水剂2或覆膜措施.
The ecological environment in Baiyu Mountain Area is fragile,with poor site conditions and sparse vegetation.In order to enrich the species diversity of Baiyu Mountain and improve the local ec-ological quality,three kinds of conifers were tested in the Baiyu mountain area,and the water-retai-ning agent and film coating were applied together and a set of water-preserving afforestation technol-ogy suitable for three kinds of conifers.The results showed that Pinus sylvestris var mongolica,Pi-nus densiflora var.zhangwuensis and Pinus banksiana could survive in Hengshan district and Jingbi-an county,with survival rates of more than 48％;(2)In Hengshan district and Jingbian County,the survival rate of P.banksiana treated with water-retaining agent 2 was the highest,reaching 68.89％and 73.33％,respectively;(3)The survival of the three conifers in Jingbian county was better than that in Hengshan district;(4)In Hengshan district,the growth of P.sylvestris var mongolica trea-ted with water-retaining measures and water-retaining agent 2 was significantly better than that treated with CK and water-retaining agent 1,the growth of P.densiflora var.zhangwuensis trea-ted with film mulching was significantly better than other treatments,and the growth of P.banksiana treated with water-retaining agent 2 was the best;(5)The growth of P.sylvestris var.mongolica and Pinus densiflora var.zhangwuensis in Jingbian county,where water-retention measures inclu-ding mulching film and water-retaining agent 2 were used,was relatively superior.For P.banksi-ana,the application of mulching film resulted in the best growth.All three tree species are suitable for planting in the Baiyu Mountains,and P.banksiana is particularly suited to the use of water-re-taining agent 2.P.sylvestris var.mongolica and Pinus densiflora var.zhangwuensis can optionally use either water-retaining agent 2 or mulching measures.
