在圃内越冬的苗木叫留床苗,留床苗植株细小,抗寒力差,因此在土壤结冻前,对留床苗应浇一次“封冻水”,以增加土壤湿度,进而保温防寒,对矮小怕冻和容易干梢的树种,可将苗畦土埂的土起出或运来砂土,在上冻前把苗木按倒后用土埋严。冻害较轻的地方,可在苗木的行间填土,待春天发芽前,再将覆土铲出。对大苗,可进行假植,假植的方法是:顺东西方向挖沟,把土放在沟南沿,堆成一个高50厘米左右的土垄,沟深50厘米左右,长、宽视苗多少而定,假植时,要把苗根放在沟里,苗梢倾向南侧,与地面约成45度角,单行摆开,然后在北侧挖第二条沟,将挖出的土埋在第一条沟里的苗根和
Winter nursery stock in the nursery is called bed nursery, stay bed nursery plants small, poor cold resistance, so in the soil before freezing, the bed should be reserved for bedtime seedlings “frozen water” to increase soil moisture, and then insulation cold, On the short afraid of freezing and easy to dry tip of the tree species, soil Miao Miao can be raised or transported from the soil, sand and seedlings in the ground before the top down by the soil buried. Frozen damage lighter places, fill lines in the seedlings of the line, until the spring before germination, then shovel the shovel out. The seedlings can be fake, fake planting method is: trenching along the east-west direction, the soil on the south along the ditch, piled into a high about 50 cm of soil ridge, ditch 50 cm deep, long, wide view seedling Depending on how many, fake plants, the seedling roots should be placed in the ditch, Miao tip leaning to the south, and the ground about 45 degrees angle, single row swing, and then dug the second ditch in the north, will dig out of the soil Buried in the first ditch seedlings and roots
