摘　　要：在气候和品种区划的基础上，系统研究了三倍体毛白杨的发展战略及其关键技术。结果表明：（1）利用两滩立地优势，营造三倍体混系丰产林。（2）体制上以区划定基地、定品种。集中育苗，统一管理，统一调拨。以审场为导向，形成产业化体系。（3）育苗上以多圃系列育苗为主，掌握其精髓，灵活运用，实现快速优质高效育苗。（4）造林技术上，就地育就地造，起、运、泡、栽一条龙作业。保证苗木质量、修枝、泡苗24h、大穴深栽、踩实浇透，是提高造林成活率之技术关键。The developing strategy of triploid Populus tomentosa and its key techniques were study systemati-cally. The resVlts show: 1) Using goodness of the beach sites to build triploid combining system high yield forests. 2) Deciding bases and varieties oa the basis of plotting systematically,concentrating seedling culture,same management and seedling transportation, developing industrial system on the direction of market - 3) In seedling yielding,many nursery system is main method,grasping its pith and applying it intelligently,realizing fast rate,high quality and high effeciency. 4)The key techniques in enhencing living rate in planting are:same site seedlling,same site planting,applying systematic managements of removing (from nursery),transporting,soaking,and planting,assuring seedling quality,pruning branches,soaking for 24 hours,large planting pit and dip planting,and steping solidly and watering fully.
