落叶花木和果树都是冬眠树种,它需要有一个冷凉环境冬眠。笔者根据它的生物学习性,连续三年对月季、石榴以及桃、李等近20种盆栽花木和盆栽果树的越冬,均采用冷窖贮藏。据88年冬检测:当窖外气温零下20℃时,窖内温度是0℃;窖外气温零下22℃时,窖内温度是零下2℃,最低窖温曾达零下5℃,塑膜上挂一层薄冰,但还没有发生冻窖死亡现象。实践证明:冷窖越冬可万无一失。它的好处是,第二年春季出窖早,抗性强,发枝壮,开花早,花大鲜艳。它既不用温室升温,节省燃料费用,又减去冬季管理时间。是解决养花多,越冬难的一种好办法。现介绍如下,供参考。
Deciduous trees and fruit trees are hibernation species, it needs to have a cool environment for hibernation. The author according to its biological habits, for three consecutive years of rose, pomegranate and peach, plum and nearly 20 kinds of potted plants and potted fruit trees in winter, are used cold cellar storage. According to 88 years winter test: when the temperature outside the cellar minus 20 ℃, the temperature inside the cellar is 0 ℃; cellar temperature is minus 22 ℃, cellar temperature is minus 2 ℃, the lowest pit temperature has reached minus 5 ℃, plastic film Hanging a thin layer of ice, but the death of frozen pits has not occurred. Practice has proved that cold winter cider can be foolproof. Its advantage is that the second spring cellar early spring, strong resistance, strong branches, early flowering, flowers brightly colored. It neither uses the greenhouse to warm up, saves fuel costs, minus the winter management time. It is a good way to solve the problem of raising flowers and overwintering. Now introduced as follows for reference.
