芦荟喜暖畏寒,当气温降到10℃～12℃时,就基本停止生长;当降到5℃以下时就会出现冻害,表现为叶片呈红褐色,易感染软腐病或根腐烂;气温降到0℃以下,即使很短暂的时间,也会造成冻害,出现叶片渍状冻伤现象,甚至造成全株死亡。可见5℃是盆栽芦荟安全越冬的最低温度线。我国大部分地区冬季都有0℃以下的低温,盆栽芦荟如何安全越冬是一个很关键的管理问题,根据笔者的尝试将经验作如下介绍:首先加强耐寒锻炼。在芦荟越冬前的秋末冬初之际,增施腐熟的有机肥,特别注重磷肥的施用,你可将豆浆渣发酵再加入适量的过磷酸钙,施于盆内根系附近,并让其有充足的光照,使其体内积累较多的糖分,以抵抗严寒的侵袭。
Aloe Vera warm chills, when the temperature dropped to 10 ℃ ~ 12 ℃, it basically stopped growing; when it fell below 5 ℃, there will be frost damage, the performance of reddish brown leaves, susceptible to soft rot or root rot; The temperature dropped below 0 ℃, even for a short period of time, can also cause frost damage, there leafy frostbite phenomenon, and even cause whole plant death. Can be seen 5 ℃ is the lowest temperature of potted aloe winter overwinter. Most parts of our country in winter have a low temperature below 0 ℃, potted aloe how to overwinter winter is a very critical management issues, according to the author’s experience will be introduced as follows: First, to enhance cold-resistant exercise. Aloe winter before the beginning of the winter, the occasion of the increase of maturity of organic fertilizer, with special emphasis on the application of phosphate fertilizer, you can fermented soybean milk and then add the right amount of superphosphate, applied to the pot near the root system, and let it have sufficient Of the light, so that the accumulation of more sugar in the body to resist the cold invasion.
