What should Tomb-Sweeping Day pay attention to after potted flowers?
1. Maintenance and management of indoor potted flower decoration in winter. When winter comes, we should pay attention to the following points in the maintenance management and indoor decoration of potted flowers: all kinds of potted flowers have different requirements on temperature, so it is impossible to meet the needs of all kinds of potted flowers in the same room. So the indoor temperature can't be too high or too low. If it is too high, the flowers will wither easily, if it is too low, it will affect the normal growth. Warm potted plants can be placed near internal heat sources or sunny places, and cold-resistant potted plants can be placed in the shade or near entrances and exits. In a humid room, potted plants that like drought should be placed in a place with strong light and good ventilation. If placed in the shade, it will cause false growth; Potted flowers that like humidity should be placed in places that are not suitable for exposure and humidity. If the air is too dry, the tip will turn yellow. Water frequently to keep the soil moist, and some potted flowers often spray water on the leaves to create a moist environment to meet the requirements of potted flowers for water. Indoor ventilation, potted flowers that like to dry should be placed in a well-ventilated place. When it is sunny at noon in winter, it is necessary to open the window properly to let the air circulate. It seldom opens or doesn't open on snowy days. At the same time of indoor sanitation, we should always spray water on the leaves to remove the dust on them, so as to facilitate the breathing of plants. Residual flowers and dead branches should also be cut off in time. Replacement of potted flowers Indoor potted flowers are affected by insufficient sunshine, insufficient humidity, small air flow and excessive dust. Especially some precious and famous flowers, such as yellow leaves, dead branches or rotten roots, are hard to raise. Therefore, indoor locations should be changed frequently, preferably every 5-7 days 1 time. When changing the location of potted plants in winter, we should pay attention to cold protection. Generally, at noon on a sunny day, the replaced potted plants cannot be frozen. Second, there is a way to place potted flowers in winter. After entering the winter, potted flowers should be moved indoors one after another, and they should be placed properly after entering the room. Flowers that bloom in winter and spring, such as crab claw orchid, cyclamen, poinsettia, camellia, etc. Carnation and snapdragon planted in autumn, and warm flowers (Milan, Jasmine, Prynne and Hibiscus) that like light should be placed on the window sill or in the sunny place; Flowers that like semi-shade in summer and light in winter, such as Clivia and upside-down golden bell, should also be placed in sunny places; Flowers that like warm and semi-light, such as asparagus, begonia and rhododendron, can be placed away from the windowsill; Evergreen flowers and trees that like light but are resistant to low temperature or dormant flowers, such as osmanthus, citrus, etc., can be placed in the shade to scatter light; Other flowers, such as potted lotus, water lily and other flowers that are resistant to low temperature and defoliation or have low light requirements, can be placed in a cool place away from light; Pomegranate, rose, fig, etc. It should be frozen outdoors for a period of time, and then moved into a cool place indoors for storage. Third, the warm-keeping method of potted flowers in winter. Mass production can spend the winter in the greenhouse, and a small amount of potted flowers can be used as simple greenhouse insulation. Simple greenhouses can be built on balconies and terraces with bamboo or iron bars, covered with plastic film and covered with straw at night. Indoor, you can insert thin bamboo chips or lead wires around the flowerpot to form an arch (about 10 cm higher than the plant), cover it with a transparent plastic film, tie it tightly along the mouth of the flowerpot with a rope, and put the potted flowers in a sunny place. If the weather is sunny and the temperature is high, the film can be uncovered for ventilation at noon to avoid rot. You can also leave a few small holes in the film to facilitate ventilation. Generally, there are water droplets in the inner layer of the film in the form of clouds, indicating that the temperature and humidity are suitable. Uncover the film after pouring water, and cover it after the water evaporates for a period of time. The newly cut branches can't be covered, because the wound is easy to mildew and rot before it heals, causing death. 4. The water and fertilizer management of potted flowers in winter is different from other seasons because of the low temperature. Because of the time relationship, clever management is particularly important. Now, based on experience, talk about this skill. In winter, it is advisable to water potted plants from 10 am to 3 pm, and the water temperature should be roughly close to the soil temperature and air temperature. Too high or too low will stimulate potted flowers, affect the normal overwintering of flowers, and even lead to deciduous leaves, rotten roots and even death in serious cases. The number of watering potted plants in winter and the amount of watering each time are less than those in other seasons. Generally, indoor potted plants are watered once a week, and balcony potted plants are watered twice a week. Water thoroughly every time, and avoid watering with "half-baked water", because the absorption function of root system is weak in winter, and it is easy to cause root rot if it is too wet, and it will die of dehydration if it is too dry. In winter, in addition to maintaining the needs of basin soil by watering, the branches and leaves of plants should be properly sprayed with water. For example, for foliage bamboo, pineapple, asparagus, spring feather, rubber tree, Hulk, green radish, ruby and so on. Spraying water can not only wash away the dust on the leaves, but also make them look brighter and fresher. For camellia, Clivia, plum, Chimonanthus praecox, primrose, cyclamen, etc. Keeping plants moist can not only make branches and leaves full of vitality, but also accelerate the expansion and opening of flower buds; For flowering flowers or inflorescences, water spraying should be changed to avoid premature fading of flowers. Used for bamboo, pyracantha, bergamot, kumquat, etc. Fresh leaves can be brightened by spraying water. Fertilization How to fertilize potted flowers in winter depends on the types of potted flowers. Potted flowers in dormant state, such as pomegranate, begonia, hibiscus, cactus, begonia bulbifera, Prynne, Milan, Eupatorium odoratum, Jasmine, Rose, Peony, Podocarpus, etc., do not need fertilization. Appropriate amount of compound fertilizer can be applied to foliage potted flowers, such as Phyllostachys praecox, spring feather, peach leaf coral, Liriodendron chinense, rubber tree, Eupatorium odoratum, asparagus, hydrangea pine and so on. And a small amount of granular fertilizer can be buried in the soil. Phosphorus and potassium fertilizers can be applied to ornamental potted flowers, such as cyclamen, camellia, Chimonanthus praecox, plum blossom, chrysanthemum morifolium, primrose and Clivia. 0.2%-0.3% potassium dihydrogen phosphate solution can be applied, and fertilization can be stopped after the flower buds open. Ornamental fruits should be applied with calcium superphosphate granular fertilizer, such as bamboo, kumquat, bergamot, generation after generation, winter coral and so on. The condition of fertilization is that the room temperature must be higher than 10℃, otherwise the fertilizer is not easy to absorb. After autumn, the temperature begins to drop, so attention should be paid to fertilization, pruning, insect prevention and warmth of potted flowers. First, rational fertilization, autumn fertilizer is extremely important for the growth, flowering and fruiting of flowers and trees in autumn and winter, as well as enhancing the cold resistance of branches, so most flowers and trees need to be fertilized in autumn. Second, shaping and pruning. There are many shoots of potted plants in autumn.
