What are the precautions for orcidaceae breeding? The leaves of Orchidaceae are yellow. What’s the matter with dead leaves? One by one, speak with facts, with practical experience to take you to raise the flowers at home. Orchidaceae is the most elegant, temperament, fragrance of a flower, can be described as “unparalleled”.
However, the requirements of Orchidaceae in the management room are also relatively high. Its plant technology is different from other common flowers as simple and easy, planting Orchidaceae must be from the selection of plant materials, fertilizer and water supply frequency, environmental light, humidity, temperature adjustment and many other aspects. So, what management matters should be paid attention to when breeding orcidaceae? What’s the matter with the yellow leaves of Orchidaceae?
1.Selection of planting materials
In order to plant Orchidaceae, it is absolutely not allowed to use ordinary soil. It is necessary to select granular materials that are loose and breathable, have certain water absorption and drainage properties, and are rich in organic matter. All kinds of materials, such as peanuts and peanuts, such as peanuts and peanuts. In addition, some minerals, such as perlite, can be added. The plant material with appropriate proportion of these materials has good water absorption, hydrophobic and air permeability. In addition, it contains high humic nutrients, and the growth and development of orcidaceae root system is particularly suitable.
2.Frequency of fertilizer and water supply
Ochidaceae is wet but afraid of water, light and fat. Therefore, we should master the word “run” when watering orcidaceae. If the surface of the plant material is wet, it can not be watered. If the plant material on the pot surface is dry 2-3 cm below, it can be watered. When watering, we should master the principle of pouring thoroughly, but we can’t make it wet for a long time, let alone water on the pot surface. Orcidaceae should use slow-release granular fertilizer or comprehensive water-soluble fertilizer as far as possible. The operation is simple and convenient, and has good effect. To avoid the use of ordinary compound fertilizer directly sprinkle on the pot. When applying fertilizer, we must master the principle of “better light than thick, thin fertilizer frequently applied”.
3. Lighting and ventilation
Any flower can’t grow well without proper light. In order to grow well, Orchidaceae must also adjust the light environment suitable for its growth. According to the species of Orchidaceae, the illumination of nature should be simulated. For example, the illuminance of Orchidaceae, such as Cymbidium ensifolium and Chunjian, can be controlled between 60% and 70%. Cymbidium goeringii and Cymbidium sinense will have lower light requirements. However, Cymbidium faberi has the strongest light requirement, which can only cover 10% of the light during the growth period, or only cover the hot light in midsummer, and accept more light at other times. Because of the different types of Orchidaceae, their light requirements are different, so they can not be treated equally. The ventilation condition of orchid planting environment is particularly important when growing orchid orchid. It is better to place the orchid pots on the shelf, which will effectively increase the ventilation and air permeability of orchid pots. Fans must be set up in the orchid planting area. After spraying or watering the orchid, and when the rainfall is heavy and the humidity is heavy in summer, the fan should be turned on to improve ventilation.
4.Humidity and temperature
Ochidaceae was born in a valley, and the humidity of the environment is naturally relatively high. Therefore, we should try our best to simulate the natural environment when we breed artificially. While setting up the shading net, we should often sprinkle water on the ground when necessary to increase the environmental humidity of the orchid planting site. No matter what kind of orgidaceae, the humidity of the environment should be kept above 60%. Ochidaceae is an aerial rooting plant. It likes the high humidity of the environment during the growth period, but avoids the high humidity of the plant materials in the pot. Among the orchids, Cymbidium goeringii and Cymbidium faberi are the most hardy species. The minimum temperature of potted Cymbidium goeringii and Cymbidium faberi should not be lower than – 5 ℃. Even if vernalization is needed, the temperature should be adjusted between – 3 and 10 degrees. For Cymbidium sinense, Cymbidium ensifolium and other species of Orchidaceae, the temperature should be adjusted above 5 ℃ and below 15 ℃, so that they can safely spend the dormancy time in winter.
5. Pest control
At the same time, we should do a good job in the prevention and control of diseases and insect pests. There are many reasons for orange leaf wilting. For example, the root rot caused by excessive soil moisture, and reed head dehydration caused by excessive fertilization, low environmental humidity, natural aging and many other factors may lead to yellow leaves and withering phenomenon. This should be based on the actual situation to find out the causes, and then the right medicine, take measures.
