Longleaf orchid is an epiphytic series in the orchid family, growing mainly in the shade of trees, on rocks, is more common in southwest China, has a high garden cultivation value, since the evaluation is so high, so how to grow it? Just look at it.
First, growth characteristics
Since it can grow in the shade, it means that its shade tolerance is not bad, but also afraid of sunlight, its most suitable growth temperature is between fifteen and twenty degrees, if the temperature reaches more than thirty degrees, then its growth will have a series of problems, the natural low temperature is the same, but the state of performance is different, the impact will affect the growth of the plant, and even the survival effect; the light situation is to temporarily stop growing.
When the temperature in the environment is too high, coupled with the intensity of light, it will sunburn its leaves within a day or even show signs of scorching, if the temperature is too low, it is necessary to move indoors in time to maintain to avoid frostbite on the leaves. The best choice for soil contains a lot of rotting fertile texture, and the drainage must be good to avoid soil agglomeration, which is more perfect if it can be acidic.
Second, the method of reproduction
1. Sowing method. The best seed sown is not cracked, first use alcohol to disinfect its surface, and then take out the seed, rinse it three times with sterile water, after which it can be sown into the seedling bottle prepared in advance, where it must be placed in a place without light, maintaining more than twenty degrees of room temperature, during which to observe whether the seed has grown into a round bulb, if there is, it can be taken out and planted, this time generally takes half a year.
2. Splitting method. Plant splitting can be carried out twice a year, these two time periods are in the spring and autumn, generally every three years can be divided. However, all plants with strong growth can be treated separately, and five pseudobulbs connected together should be preserved after separation, and the amount of watering should be reduced before branching, so that the potting soil is in a dry state. When the plant is potted, it can be covered with rubble stone at the lowest place, and then laid with coarse stones, and then fine soil, fine soil must be treated with bottom fertilizer, so that the soil not only has high fertilizer retention, but also has no poor drainage.
3. Pest defense
1. Mesothecarp. Mesozoans are very common insect pests, the ventilation effect of the general environment is not good, the appearance of high temperature and high humidity of the air will find a large number of mesozoans on the plant, and its ability to reproduce is super fast. If the number of pots planted is small, it can be manually brushed off, and if you are troublesome, you can also use the agent to spray it directly.
2. Anthrax. The disease initially spreads from the tip of the leaf to the stem, and is only a small part of the brown color at the beginning, and as the disease worsens, black spots continue to appear around it, preferably until the plant dies. In fact, the manifestation of the disease is on the leaves, if there is observation is not difficult to find, once it is aware of it, it is necessary to immediately take measures to eliminate it, so as to prevent the plant from dying on the road. When the pathology first occurs, it is sprayed with a lower concentration of agents once a week until the plant is intact.
3. White silk disease. The occurrence period of this disease is a rainy day, and the initial onset of the disease is also manifested on the leaves, and its pathology is white spots.
