Different flower growth, temperature requirements and regulation methods

First, make use of the temperature difference in different parts of the room to arrange the potted flowers reasonably.

1. The temperature in different locations of the room is different, so it can be placed according to the temperature requirements of flowers.

2. Flowers that like high temperature can be placed near the heating, stove, and sunny south window.

3. Keep away from the heating, stove or near the door, the temperature is low, you can put low-temperature, shade-resistant flowers.

4, such as cyclamen, primroses and other flowers that are afraid of high temperature can be placed on the north balcony, while the heat-resistant flowers can be placed on the south balcony.

II. Prevention of cold injury and freezing injury

The main results are as follows: 1. Cold injury is simply that the sap of the plant does not freeze, but because of low temperature, it affects the normal physiological activities of the plant, resulting in physiological drought, wilting of tender leaves, leaf shedding and other phenomena. Freezing injury refers to the freezing of plant cell sap.

2. When the indoor temperature is above 15 degrees in winter, most flowers can survive the winter safely, but when the temperature is lower than 2-3 degrees for a long time, it can lead to yellow leaves, fallen leaves and even death.

3. Wealth trees: when the winter temperature is lower than 16 degrees, the leaves turn yellow and fall off, and die when the temperature is below 5 degrees; tortoise back bamboo: it can endure 5 degrees low temperature for a short time, and freezing injury occurs easily when the temperature is lower than 5 degrees for a long time; velvet taro: the winter temperature should not be lower than 13 degrees; thick-leaf Oncidium: the winter temperature should not be lower than 12 degrees. Candle: the winter temperature should not be lower than 15 degrees, otherwise the Buddha's bud will not be formed. when the temperature is lower than 13 degrees, there will be frost injury.

III. Regulation of soil temperature

1. Make a good planting bed or ridge in spring, and then cover with plastic film, which can not only increase the low temperature, promote the growth of flowers, but also increase the ornamental effect.

2. When raising seedlings indoors, you can put the flowerpot next to the heating to increase the soil temperature.

IV. Regulation of high temperature

1. When it is hot in midsummer, spray well water on the plant in the morning and evening to reduce the soil temperature.

2. put the plants that are afraid of high temperature on the north side of the house or in a shady place.
