一、树木移栽的时期北方最佳移栽时期是早春,树木带土球移栽及较易成活的落叶乔木裸根栽,加重修剪,均可成活。需带大土球移栽较难成活的树木可在冬季土壤封冻时带冻土移栽,但要避开严寒期并做好土面保护和防风防寒。春季以后尤其是盛夏季节,由于树木蒸腾量大,移栽树木不易成活,如果移栽必须加大土球,加强修剪、遮荫、保湿也可成活,但费用加大。雨季可带土移栽一些针叶树种,由于空气湿度大也可成活。落叶后至土壤封冻前的深秋,树体地上部处于休眠状态,也可进行树木移栽。南方地区尤其是冬季气温较高的地区,一年四季均可移栽,落叶树还可裸根移栽。二、树木处理移栽树木必须做好树体的处理,对落叶乔木应对树冠根据树形的要求进行重修剪,一般剪掉全部枝叶的1/3-1/2;树冠 First, the period of transplanting trees The best transplanting period in northern China is early spring. The transplanting of trees with earthballs and the bare-rooted deciduous trees that are more likely to survive, aggravating the pruning can all survive. The trees that need to be transplanted with a large soil ball more difficult to survive may be transplanted with frozen soil when the soil is frozen in the winter, but should avoid the cold period and protect the soil surface and prevent wind and cold. After spring, especially in midsummer, transplanting trees are not easy to survive because of the large amount of transpiration. If transplanting, soil must be enlarged to enhance pruning, shading and moisturizing, but the cost will increase. Rainy season can bring some soil transplanting conifer species, due to the air humidity can also survive. Autumn leaves to soil before freezing late autumn, the upper part of the tree dormant, but also for transplanting trees. In the south, especially in areas with high winter temperatures, transplanting can be carried out throughout the year and deciduous trees can also be transplanted with naked roots. Second, the tree handling Transplanting trees must do a good job of tree treatment, tree deciduous tree response to tree requirements of heavy pruning, the general cut off all the branches 1 / 3-1 / 2; crown
