我住在单元楼内,封闭阳台外的防盗窗较宽,其间种养了一些盆花,它们的冬天是这么度过的——严寒的冬季,地栽植物的根系深扎于土壤,一般不会结冰,而盆栽植物的根系在有限的盆土里,整个暴露在冷空气中,一旦盆土冻透,根部就很容易结冰死亡。这也就是为什么有些较耐寒的花木地栽可以自然越冬,但上盆却难以过冬的原因。 I live in the unit building, the burglar windows outside the enclosed balconies are wider, with some potted flowers, and their winter so spent - in the frigid winter, the roots of the plants planted deep in the soil, generally not Frozen, and the roots of potted plants are in limited basin soil, exposed to cold air as a whole, and once the basin soil has been frozen, the roots can freeze and die easily. This is why some of the more cold-tolerant plants can naturally wintering, but the pot is difficult to winter reasons.
