在绿化施工中,有时为了某些特殊要求,不得不进行反季节(5～9月间)植树。此时树木正处在生长旺季,阔叶树已具有浓绿的枝叶,针叶树的枝叶也已全部展开,如进行移植,对树木的成活是个严峻的考验。如何减少损失,提高反季节植树的成活率呢?我们经过多年的实践,总结出以下几点经验: 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,反季节植树时土球径应增大到干径的10～12倍,同时土球一定要包
In the greening construction, sometimes for some special requirements, had to carry out the anti-season (May to September) planting trees. At this time the trees are in the growing season, broad-leaved trees already have dark green foliage, conifers foliage has also been fully expanded, such as transplantation, the survival of trees is a severe test. How to reduce losses and improve the survival rate of anti-season tree planting? After years of practice, we summed up the following experience: 1, increase the soil ball seedlings, the soil ball should be appropriately increased, the normal normal season of tree seedlings, The size of the soil ball is 8 to 10 times of the dry diameter. The diameter of the soil ball should be increased to 10 to 12 times of the dry diameter in the season planting, and the soil ball must be packed
