道路、公园、宾馆、庭院等地的绿化,需要较大的树苗和成树,因此要很好掌握大苗(成树)特别是常绿树种的大苗移植方法。大苗移植首先是选树,要选择根系完整的实生苗或扦插苗,尽量不用根蘖苗。因此树的高度、粗度、干形、冠形等都要符合理想要求。在土壤种类方面,如果是选用落叶阔叶树种,采取裸根移植的可不必考虑土类。如果是选用常绿针叶树种,就必须考虑能否带土坨起树,因此应选择生长在粘土或粘壤土上的树苗。
Roads, parks, hotels, courtyards and other places of greening require large saplings and trees, so to master the big seedlings (especially trees), especially evergreen species of seedlings transplantation method. The first is the selection of seedlings transplant trees, to choose a complete root seedlings or cutting seedlings, try not to root tillering seedlings. Therefore, the height of the tree, coarseness, dry shape, crown shape and so on should meet the ideal requirements. In terms of soil types, if deciduous broad-leaved tree species are used, it is not necessary to consider the soil type when taking a bare root transplant. If it is the use of evergreen conifers, we must consider whether it can take Tuo Tuo tree, it should choose to grow in the clay or clay loam on the saplings.
