苗木在起苗后(种条采集或购进后),为防止脱水,保证苗木和种条质量,凡是不马上用于造林或育苗的,都要按树种分等级进行假植。根据假植时间长短分为临时假植和越冬假植。一、临时假植。苗木和种条暂时贮存,不久将用于造林、育苗或运往外地,就需要进行临时假植。方法是;顺东西方向挖沟,一般沟深30厘米。宽1米左右,然后小束或单株靠一头斜放或立放一层,用湿细土或湿细沙将根部盖严,厚度为20～3O厘米,并要踩实。苗木或种条不可过厚,要使根土密接不能“搭窝”。然后再摆下一层,以此类推。各层数量要相等, Seedlings in the seedlings (seed collection or purchase), in order to prevent dehydration, seedlings and seed quality assurance, those who are not immediately used for afforestation or nursery, should be grafted according to tree grading. According to the length of false planting is divided into temporary planting and winter planting. First, the temporary planting. Temporary storage of seedlings and seeds, which will soon be used for afforestation, nursery or transportation, requires temporary planting. Method is; along the direction of trenching ditch, the general ditch 30 cm deep. Width of about 1 m, and then beam or plant by oblique oblique or stand up a layer of wet fine soil or wet sand will be covered with a thick root, the thickness of 20 ~ 3O cm, and to step on real. Seedlings or seeds can not be too thick, so that the root can not close And then put a layer, and so on. The number of layers should be equal,
