美人蕉冬天怎么过冬

智人

对于美人蕉冬天怎么过冬我们可以根据不同的地域选择不同的过冬方式,比如长江以南地区就不用管了完全露天过冬就可以,而长江以北地区可以在霜降前,把美人蕉老棵从茎基部割去,用草木灰涂抹割伤处并晾晒伤口,以免伤口感染腐烂。

  
3、4天后,伤口呈干燥状,再用锯末或稻草等保暖物覆盖,覆盖的厚度约15-20厘米,保暖层以美人蕉茎基部不爱冻害为度。

在整个冬季经雨雪淋浇,覆盖物上层受潮发热,起到保暖保湿作用,如无保暖物覆盖,可用土埋。先用庄稼或柴草扎一小捆“把子”,高度以露出埋土层为宜,埋土的厚度要超出冻土层,柴草把子的底端要放在美人蕉的茎基部,起到透气的作用,以防美人蕉块茎密不透气窒息而腐烂。

翌年春解冻后,可把覆盖物除去大部分,留下薄薄的一层,以防春天遭受“倒春寒”的冻害,3、4月份,美人蕉便可破土出芽了。

如果北方极寒地区可以在深秋植株枯萎后,要剪去地上部分,将根茎挖出,晾晒2-3天,埋于室内通风良好的砂土中,不要浇水,保持5℃以上即可安全越冬。
