1.加大土球。起苗时,土球要适当加大,一般正常植树季节起苗,土球大小是干径的8—10倍,反季节植物时土球径应增大到干径的10—12倍,同时土球一定要包好,在运输中上下车不能散。 2.修枝、摘叶、缠干。树苗挖起后要放倒,修剪内膛枝、枯枝,保证树形。若是阔叶树,树叶要摘除80%,针叶树只修枝即可。随后将主干用塑膜包好,再用草绳缠干,直到分叉处,以防树干水分蒸发,成活后到秋季再将薄膜除去,若是截干的树苗,则用塑料带绑扎住截口或在截口处涂油漆。
1. Increase soil ball. When raising seedlings, the soil ball should be properly increased, normally the normal seedling season seedlings, soil ball size is 8-10 times the dry diameter, reverse season plant soil diameter should be increased to 10-12 times the dry diameter, at the same time Earth ball must be wrapped in the transport can not get off on the ground. 2. Pruning, pick leaves, wrapped around. Sap after digging to be tipped, trimmed borer branches, dead branches, to ensure that the tree. If broad-leaved trees, leaves should be removed 80%, conifers can only pruning. Then the trunk with a plastic wrap, and then straw wrapped around the stem, until the bifurcation, to prevent the evaporation of water from the trunk to survive after the fall and then remove the film, if the cut stem saplings, then use plastic banding laparotomy Or painted at the nip.
