树苗起运工作做得好坏,直接影响苗木的产量和质量,同吋也影响造林成活率和造林后林木的生长发育情况。因此,必须重视做好苗木的起运出圃工作。一、掌握起苗时间。一般从秋季落叶后到翌年春季树液开始流动前(即苗木休眠期)进行。秋季造林所用苗木,应在落叶后,随起苗随栽植,这在霜冻前根系能够恢复一部分创伤,来春可较早生长。根部含水量较高,不宜较长期假植的落叶树(如榆树)和常绿树进行
Saplings shipped from doing good or bad, directly affect the yield and quality of seedlings, with the same also affect the survival rate of afforestation and afforestation after the growth and development of trees. Therefore, we must attach importance to the nurturing of nursery stock nursery work. First, grasp the seedling time. Generally from the autumn leaves to spring flow the following year before the start of the flow of liquid (ie seedling dormant period). Autumn seedlings used in afforestation, should be in the leaves, with the seedlings with planting, which can restore part of the root system before the frost trauma, spring can grow earlier. Root moisture content is higher, not longer than the long-leaved deciduous trees (such as elm) and evergreen trees
