观叶植物（观叶花）的冬季管理

观叶植物（观叶花）多产于热带和亚热带地区。为了在北方寒冷的冬天中生存，并保持一定的观叶植物（观叶花）效果，必须注意以下问题。
一、放置。观叶植物（观叶花）进入室内后，应分门别类摆放，喜欢阳光的植物应放在阳光充足的窗边；如果是耐荫性强的植物，应放置在没有阳光的地方，或稍微散射。光。对于观叶植物（观叶花）的吊盆和吊盆，也要经常变换位置，使它们能够适当地接收到一些光线。一些带有彩色斑纹的植物，如金心龙血树、锦紫苏等，在散射光下栽培，有利于色彩的充分表现。阴影过多会使颜色消失或不亮，光线过强会使叶子变黄失去颜色。图案。因此，冬春季应给予一定的光照，以利于植物生长，增强抗逆能力。
二、调节温度。大多数观叶植物（观叶花）的耐寒性和耐高温性较差。冬季到来后，室内昼夜温差应尽量小。℃左右。另外，同一个房间会有温差，所以耐寒性低的植物可以放在高处。放在窗台上的观叶植物（观叶花）易受寒风影响，应用厚窗帘遮挡。对于极少数极耐寒的物种，可以采用局部隔离或小房间来保暖过冬。
三、调节湿度。如果室内植物的叶子在冬季枯萎掉叶，主要原因是空气湿度，必须尽可能创造一个相对潮湿的环境。The leaves should be regularly sprayed with water mist at about 20°C on the leaves once or twice a day, and it is advisable that the leaves do not drip. If conditions permit, it is best to sprinkle water frequently around the potted plants to increase the air humidity in a small area. If the indoor air is very dry (heating or fire is installed in the room), and the leaves are browned, the plastic bag full cover method should be adopted as soon as possible to seal and isolate the seriously damaged potted flowers, so that they can be kept in a small environment with relatively humid air. Gradually recovered to prevent further aggravation of the harm.
四、Appropriate water and fertilizer. Foliage plants (foliage flowers) generally have more and larger leaves, and the water in the body volatilizes quickly. However, due to the low temperature in winter, the growth is basically stopped, the absorption function of the roots is weakened, and the water demand is very small. Therefore, as long as the leaves do not lose water and become shriveled, it is better to keep the potting soil dry. Do not overwater, as it will easily cause the root system to rot and cause the leaves to die. Except for a few flowers and trees that continue to grow in winter, apply light fertilizer and water once a month, most foliage plants (foliage flowers) flowers and trees should be completely fertilized to prevent the normal dormant flowers and trees from rising in temporary temperature due to the effect of fertility. It germinates from time to time, and when the temperature drops, it cannot age normally, consumes the nutrients stored in the body, and makes it unable to dormant normally, reducing the cold resistance ability.
Anti-freezing method for foliage plants (decorative flowers)
Indoor foliage plants (foliage flowers) winter cold and frost protection is an important technical link in normal management. Whether this work is handled properly or not directly affects its cultivation and utilization effect. Because indoor foliage plants (foliage flowers) are native to tropical and subtropical regions, the sensitivity to low temperature developed during the development of the system. The temperature is too low for cold damage or freezing damage.
When the temperature is lower than the normal overwintering temperature, its normal physiological activities will be affected, the absorption capacity of roots will decrease or stop, and the shoots will be wilted and old leaves will be wilted and old leaves will fall off; if the low temperature time is not long, it can be recovered , a little longer will cause the plant to die.
