入秋后,天气逐渐转冷,不耐寒花卉陆续移入室内。天气不太冷时,尚可打开门窗通通风,但气温下降到一定程度后,就不能利用门窗通风了。尤其是在寒冷的北方,为了保持室温,门窗不仅不能开,还要紧闭,这样就阻断了室内外空气的流通。众所周知,花卉无论是生长期还是休眠期,都是需要适当通风的,那么,在盆花秋季入室后到翌春出室前该怎样给其通风呢? After autumn, the weather turns cold gradually, and the cold-hard flowers are gradually moved into the interior. When the weather is not too cold, you can still open the doors and windows ventilation, but the temperature dropped to a certain extent, you can not use the doors and windows ventilation. Especially in the cold north, in order to maintain room temperature, doors and windows can not only open, but also closed, thus blocking the flow of indoor and outdoor air. As we all know, flowers, whether growing or dormant, need to be adequately ventilated. So how do you ventilate flowers before they fall into the room in the autumn?
