一年生落叶松幼苗,冬季易受冻害或干旱枯梢,为防止这些现象发生,并为秋翻、春耕提供方便条件,使翌春早期移植提高成活率,须在当年秋季起苗,进行越冬假植或坑藏、窖藏、垛藏等方法防寒越冬。垛藏苗木,集约经营,便于管理,苗木可安全越冬;翌春受季节气候限制较少,可提早取苗,顶浆移植,提高成活率。我圃落叶松幼苗历年来都采用此法越冬,效果很好。1、选地:要选择地势高燥、背风向阳,并便于管理的地方堆垛藏苗.2、时间:在结冻前(十一月上、中旬),不宜过早,以免垛内发热(?)苗;过晚则结冻,作业不便。
Year-old larch seedlings, the winter susceptible to frost damage or dry shoots, in order to prevent these phenomena occur, and for the autumn turn, spring plowing to provide convenient conditions for the next spring to improve the survival rate of transplants, must be in the autumn seedlings, the winter planting Or pit possession, cellar storage, storage and other methods of cold winter wintry. Duck possession of seedlings, intensive management, easy management, seedlings can be safe wintering; next spring by the seasonal climate less restrictive, early seedling can be taken, apical plasma transfer, improve survival. I nursery larch seedlings over the years have adopted this method winter, the effect is very good. 1, the election site: to choose high terrain, leeward sunny, and easy to manage place stack Tibetan seedlings .2, time: before freezing (November, mid), not too early to prevent heat within the stack ( ?) Seedlings; too late, frozen, homework inconvenience.
