How to maintain and manage orchids in winter?

Orchids stop growing in winter, but the management of this period is directly related to the growth of the next year. Improper management in winter can easily lead to frostbite, empty roots and black spot disease, and even serious death. So we must pay attention to the management of orchids in winter. First, master the correct time to enter the house. The temperature difference in different areas in the same season is very large, and the time to enter the house cannot be generalized. The time to enter the house depends on the local climate change. If it is Chunlan, you can choose to enter the room the day before the weather forecast will freeze. Someone enters the room below 10, which is not conducive to the development of flower buds. Entering the room too early will inevitably lead to fewer or even no flower buds in the smelly days of the coming year. Therefore, as long as the temperature is not lower than the "coldness", Chunlan should be exercised at a low temperature of 0 to 10, which can also make the orchid tissue more substantial and healthy, and the new buds will flourish in the coming year. 2. Spray anti-disease and anti-insect drugs before entering the house. When the temperature is lower than 5, spray 800 times of Tobuzin or carbendazim on sunny days. If there are scale insects, pesticides such as trichlorfon should also be sprayed. Because the greenhouse temperature is high after entering the room, it is easy to produce diseases. Third, the room to prevent frozen orchids from overwintering can be a greenhouse, a general room or a plastic shed, but the minimum temperature must not be lower than 65438 0℃ to prevent frostbite. If it is lower than 0℃, it is harmful to any orchid, and orchids should not be frozen under any circumstances. When it is too cold, use an electric heater to heat it. Fourth, we should ventilate regularly. In order to prevent orchids from freezing, orchids should not be kept in unventilated places for a long time, which will make orchids freeze. In spring, orchid leaves tend to turn black to promote air convection, but it is necessary to prevent the northwest wind from blowing cold. In addition to freezing to death, it is best to open the window for air at noon. Five, to prevent the orchid pot soil is too dry in winter, orchids stop growing, and the water demand is reduced. Because orchid roots are fleshy roots, they can generally survive without watering. However, if the basin soil is dry for a long time, it will lead to the strong orchid roots becoming empty roots, but it will not be reflected from the orchid leaves for the time being. During the severe drought, Langan died. This problem often lies in the one-sided understanding that "the soil is wet in winter, but it is thought to be soaked, which leads to the dry roots." The correct way is "if you don't do it, you will fall completely." Too dry pots can be soaked in water. Sixth, to prevent long-term wet "winter is not wet" means that orchid pots can't stay wet for a long time, and it is even more difficult to avoid getting wet before drying, so they will undoubtedly be rooted. After the basin is watered thoroughly, you can bask in the sun and blow the wind until it looks like the soil in the basin is not very wet. Seven, prevent smoke Gagelin room can't use coal stoves, only electric stoves and infrared light bulbs. These heaters also need to keep a certain distance from orchids to prevent burning orchid leaves. If there is no special orchid room, orchids must be placed in places where gas can't smoke. Because orchid leaves touch air, there will be black spots on them. Eight, to prevent the winter from being too hot, orchids have been dormant. If the temperature is too high, it is not conducive to orchid dormancy. The most taboo is that orchids are in high and low temperatures, otherwise they will weaken and get sick. Therefore, the basin should not be close to the heater. When there is sunshine, we should also shade properly. Nine, prevent the leaves from being wet When the leaves of orchids are wet in spring, summer and autumn, because they are in the growing season of orchids, orchids themselves need a lot of water, and outdoor ventilation can be dried immediately, so it is not easy to appear black spots. But there is no ventilation in the greenhouse or indoors, and orchid leaves are prone to black spots, so don't spray orchid leaves before they are covered with dust. If the orchid leaves are really covered with dust, of course, you can also choose a sunny day without ice to pour the orchid leaves at noon and open the window until the orchid leaves are dry. Ten, the heart of orchids should be waterproof. When watering in winter, it is best to water it from the edge of the basin. Don't pour water into orchids. If you pour it carelessly, you should use a cloth to absorb water from the blue heart to avoid rotten heart.
