Origin Habitat
Born in a mountain junction in the mountains of 1850 meters. Production China, Northwest China (Longlin), Southwest Guizhou (Xingyi, Luodian), southeast of Yunnan to the west (勐 勐, 勐海, 河口, Jinping, Fengqing, 沧, Zhenkang, Yi, Yingjiang) , Southeast of Tibet (ink). Distributed in Bhutan, Northeast India, Myanmar, Thailand, Vietnam. The pattern specimen is collected from the northeastern of India.
Growth habits
Tooth petute is a kind of joyful perennial plants, happy in warm, moist, annual rainfall, more than 1,000 millimeters, semi-yin and half-yang, The average temperature of the average temperature above 8 ° C is better, and the growth temperature is 15 to 28 degrees. It is suitable for growth air humidity to 60%. It is not very strict on soil, and the wild is in a loose and thick tree. The skin or the trunk is growing, and some is also growing in the stone seam. It is a gas root system, mainly requires a good root permeability. It is best to ventilate and ventilated water. At a suitable temperature humidity, the growth rate is fast, and the survivability is very strong. In the late spring, in the late spring, the fourth-year stem is extracted. After flowering, the new buds are developed from the stem group, and the autumn and winter season enters the sleep period.
Reproduction method
optionally
selection, according to its growth habits, Dendrobium cultivation should be selected, the air humidity is More than 80%, winter temperatures are from 0 ° C. Artificial controllable environments can also be, the tree species should be yellow, pear trees, eucalyptus, etc., should have a longitudinal groove, a water, a lot of water, and a rough tree, and the stone is also in a cool, moist area, There should be a small amount of rot in the stone on the stone.
bracing
Select a dense value of the plant. After the flowering. Take it from the basin, remove the base from the base of the bis, With the minimum injury root, only the very small part of the interconnection is hidden, the root is opened, and it is not necessary to cut with the knife. With the main stramest as a group, then further cut the old root. The sprouts are close to the center of the basin, fill in the new matrix and compacted, that is, new plants.
Sprouted
Potted plants or part of the top or foundation of some autumn deeper stems, the bud reproduction can be performed. Select a small plant having 3-4 leafs, 2-3 roots, 4-5 cm long, cut from the masterbatch, treated with grass ash or 70% Lens zinc treatment wound, and plant seedling into the basin I.e. Wang Yi wants to plant it. Cultivation can be blooming in a commodity flower after cultivation for 2 years.
Cutting
Cutting propagation can be carried out together with the flow of pots and bracing. The stone poems have slender, stems with meat, and there are many festivals on the stems, and they can bud on the festival, so they can breed them. Choose unflowing and more fulfilling broadcast, cutting the skills into several sections, each section of 2-3 festivals, coated with grass ash or 70% in the wound. Wound. Insert the stem in a paragraph inserted into the matrix of moss and peat mixed, half of the ocean, put in a half yin, wet. No need to water 1 week after plug, then often spray moisturizing, properly shade. After 1-2 months, there was a new bud in the section, and 2-3 small roots under the sprouts formed a new plant. The new plants are connected to the old pots, and it can be bloomed in 2-3 years. The cutting time is good in 4-8 months.
Cultivation Techniques
Poed Ball
Usually use four wall porous plastic or ceramic pots, carbon roots, peat moss, bark block, wood carbon block Wait for potted materials. According to the size of the Lancale, select the flower pots of different specifications, but it is not advisable to use the large potted small seedling mouth, the above-mentioned material is soaked in water for more than 1 day. Paste bottom should be multi-mat or broken brick, depth to about 1/3 of the basin, then put the blue seedlings on the center of the pot, and insert a fine bamboo pole on one side to secure the laon seedlings, then fill other cultivated materials , Pay attention to the material between the roots.
Water
Plant in the middle of the cool cool and cool, there is a scattering light, only spray some water on the leaves, do not water water into the basin. After about 10-15 days, the two moved from the new root to the shed. The growth season is watering to maintain a moderate dry pizza with water. The growth of the trees are watering every day, and the arid season and summer are still sprayed on the ground around the flower pot to maintain high air humidity, and pay attention to ventilation. Water should be water during winter sleep. The late air humidity is often watering and moisturizing, and the spray can be watered in the form of a spray.
Temperature
The rated group culture seedlings are very sensitive to moisture, and the water is slow, dry, and low survival rate. The spray is too much, the water is burned, the temperature is high, and the humidity is also easy to cause a large scale of soft rot. The air humidity remains around 90% (seedlings have not been sent to the root), and the plant begins to be new roots. The air humidity can be maintained at 70% -80%. Planting dry and humidity is beneficial to the root of forensic buds. I avoid direct sunlight, and the sun can be seen in the spring and autumn, and the sun can be sufficient in winter, and other time is placed in a place with bright and exhaled light. Winter temperature is maintained at 8-10 ° C.
Fertilizers
Since Dendrobium is gaseous root, it is necessary to spray suitable foliaries as nutrient solutions to supply sufficient nutrients, and the benefits of early growth roots. Leaf fertilizer can select potassium nitrate, potassium dihydrogen phosphate, humic acid, and imported ternary composite fertilizer and diluted MS medium. One week in general transplantation, the plant is started to spray a bit of potassium nitrate or pelletivate potassium phosphate, spray once, and sprayed three times in 7-10 days. Three-dimensional compound fertilizer, spray 3 ‰ every 10-15 days after growing sprouts. It should pay attention to topdressing, and the first time before and after the Qingming, it is mainly mixed with nitrogen fertilizer. The second time I used a peanut drum, rapeseed cake, and the rope seed cake, calcium phosphate was added to the roots of the river, and there were still prostitutes.
Moving
The closion closing of Dendrobium is around 60%, so it is often necessary to carry out the rejection trees, so as not to be too covered or depressed. Every spring, the new time is new, combined with the harvesting of the stems to cut, and remove the stem, weak stem and patient roots, planting 6-8 years later, the pleasure is growing and re-blending .
Pests infection control
Black spot disease
When the disease is diagnosed, there is a dark brown spot, surrounded by the spot, gradually spread to the blade, severely black The spot is connected to each other on the blade, and finally wreats. This disease is often copied in early summer (3-50). Prevention and control method: Use 1: 1000 Bordeaux or Duertate 1000 times liquid to prevent and control its development.
anthrax
Hazardous blade and stem branches, the damaged leaves appear brown or black lesion, and there were occurred in January-May. Prevention and treatment method: 2-3 times with 50% polystrichum 1000 times liquid or 50% methyl Tobil 1000 times.
Coal prevention [H3>
When the disease, the surface of the entire plant blade covers a layer of coal soot black powder, which seriously affects the photosynthesis of the blade, causing the plant development. The main pathoge period of this disease from 3 to May. Prevention and treatment method: from 50% of the bacteria 1000 times liquid or 40% Lao Emulsion 1500 times liquid spray 1-2 times prevention.
Philippine Shield
This pest is parasitic in the edge of the stone of Dendrobium plant or the back of the leaves, absorbs the juice, causing the plant blades, causing the entire plant to death. It can also cause coal sickness. Prevention and treatment method: This pest is a period of incubation in late May, with a 40-magnification of a 40-dimensional effect of 1000 times or 1-3 degree stone sylidegene. It has become a shield shell but quantity, which can take a method of cutting out of the old branch blade to burn or dying.
Snail
The pest is mainly hiding in the back of the leaf, and the snister is tsned. The insects can happen more than one year. Once it happens, it is extremely harmful, and it is often possible to eat all the plants in one night. Prevention and treatment method: use bran to blend enemy insects, spread to poison bait in places where pests are often moved; spraying pests such as insects and surrounding environments, can also remove lime, saturated saline; Clean hygiene in cultivation places, the dead leaves should be removed in time.
