摘　　要：【目的】研究白榆幼苗培育及造林技术,提高白榆幼苗在种植过程中的存活率,从而确保种植项目的成功。【方法】在幼苗培育阶段进行白榆采种、浸泡催芽并选择适宜的苗圃。在造林过程中着重改善播种土壤土质,进行作床处理,然后进行白榆幼苗的播种,最后进行灌溉排水以及播种后的管理。【结果】在最后的苗木成活率中,用氮肥施肥的白榆幼苗平均成活率为82.15%,用磷肥施肥的白榆幼苗的成活率为55.36%,用尿素施肥的白榆幼苗的成活率为35.12%,氮肥施肥的白榆幼苗成活率明显较高。【结论】在白榆幼苗的培育及造林过程中,应该积极进行苗木的施肥管理,以此提高白榆造林的质量。【Objective】To study the cultivation and afforestation technology of Ulmus pumila seedlings,so as to improve the survival rate of Ulmus pumila seedlings during planting,and to ensure the success of planting project.【Method】During the seedling cultivation stage,Ulmus pumila seeds are collected,soaked and sprouted,and suitable nurseries are selected.During the afforestation process,emphasis is placed on improving the soil quality of the sowing soil,conducting bed treatment,followed by sowing Ulmus pumila seedlings,and finally conducting irrigation and drainage as well as post sowing management.【Result】In the final survival rate of seedlings,the average survival rate of Ulmus pumila seedlings fertilized with nitrogen fertilizer,phosphorus fertilizer and urea was 82.15%,55.36%and 35.12%,respectively.The survival rate of white elm seedlings fertilized with nitrogen fertilizer was significantly higher.【Conclusion】During the cultivation and afforestation process of Ulmus pumila seedlings,fertilization management of seedlings should be actively carried out to improve the quality of Ulmus pumila afforestation.
