白毛杨属白杨派,扦插生根比较困难。近年来,我圃采用埋条育苗效果较好。埋条方法简单,易于掌握,投工少,成本低,苗木产量高于扦插育苗,每亩产苗约4400株,为扦插苗的两倍。一、种条的选择和处理种条质量对提高毛白杨埋条苗的产量和质量关系很大。要选用粗壮通直、芽子饱满、木质化程度高、无病虫害的一年生苗干做种条。用大树上的萌芽条理条育苗,成活率很低。冬季或早春采集、调运的种条必需埋藏假植起来,来春育苗前将其挖出,放入清水中浸泡5～10天,尤其是经过远途运输的种条,水浸是软化皮层,吸足水分,提高埋条成活率的关键。二、整地作床
Poplar is a poplar, cuttings rooting more difficult. In recent years, I nursery embedded barbed seedling effect is better. Buried method is simple, easy to grasp, less investment, low cost, seedling yield higher than cuttage nursery stock, about 4400 plants per mu yield, twice as cutting seedlings. First, the choice of species and processing The quality of the species of Populus elliottii to increase the yield and quality of a great relationship. To choose thick straight, full of buds, a high degree of lignification, pests and diseases without the annual dry seed do. With the bud on the tree rules nursery, survival rate is very low. Winter or early spring collection, transportation of the species must be buried fake vegetation, to nursery before spring dredging, into the water soak 5 to 10 days, especially after long-distance transportation of species, flooding is softened cortex, sucking Enough water, improve the survival rate of buried key. Second, soil preparation for the bed
