一、选择适宜的栽种时间是毛白杨成活的关键。冬栽毛白杨最佳时间是从立冬到小雪这半个月的时间,因为这一时期气温都在5℃以上,苗木的叶子都已大部分脱落,停止生长,进入休眠状态,这时不知不觉地给树苗搬了家,栽种上就容易成活。过早苗木未停止生长,过晚气温低,苗根易冻害,也不易成活。二、栽前整地挖大穴。冬季风大天寒栽种时略深一点好,毛白杨2～3年生苗木,树穴不能小于80立方厘米,最好1立方米。树穴底部还要翻松,挖出的表土放在穴的一边,下部的生土放在穴的另一边,栽种回填时,先填表土、后填生土。这样,深栽踏实树苗容易成活,成活后有利速生丰产。
First, select the appropriate planting time is the key to poplar survival. Winter planting white poplar is the best time from the winter to the snow half a month, because the temperature during this period are above 5 ℃, most of the leaves of seedlings have been shed, stop growing, into sleep, then I do not know Feel the seedlings moved home, planted on the easy life. Early seedlings did not stop growing, late temperature is low, easy to fry damage, is not easy to survive. Second, planted before digging a large hole. When the winter monsoon planting a little bit better, Populus 2-3 years old seedlings, tree trunks can not be less than 80 cubic centimeters, preferably 1 cubic meter. The bottom of the tree hole should be loosened. The topsoil excavated should be placed on the side of the hole. The bottom of the raw earth should be placed on the other side of the hole. When planting the backfill, first fill the topsoil and then fill in the earth. In this way, planting saplings is easy to survive steadily, survival is conducive to fast-growing yield.
