Cultivation and Management of Cymbidium in the Mountain of Han Lan

Many orchid lovers, especially in recent years, especially like Han Lan, because the beauty of Han Lan is the beauty of many aspects. Leaf-shaped long leaves are like swords, short leaves are iconic, and bow-shaped leaves are like dragons out to sea. Cold orchid color flowers are the most, red, orange, yellow, green, purple, blue, red, black and white, the beauty of the flower is like dragon flying Phoenix dance, white crane Changming, Ziyan returning to the nest, Dapeng spreading its wings, fairies coming down to earth, and so on. Flowers bloom fragrant, mellow for a long time, a flower in the room, a room full of fragrance. Cold orchid integrates the beauty of all kinds of orchids and the spirit of all things.

Cold orchids like shade and dampness, and the primary alpine foggy forests are mostly distributed in areas with an altitude of 500 meters, 1000 meters above sea level, where trees are dense, shade is large, the ground forms a thick humus layer, and the land is fertile and loose. In the primeval forest, the cold orchid with good topography has many seedlings, beautiful leaves and well-developed roots.

In the orchid picking in the deep mountains for many years, the author also found that the vitality of the cold orchid is very strong. Sometimes the big orchid is thrown on the tree stump or stone when the farmers dig bamboo shoots, it can survive, blossom and survive, but the new seedlings are smaller. Cold orchid is located in different terrain, the growth of orchid seedlings are also different, such as growing in the sun, soil dry terrain of the orchid seedlings are shorter and smaller, the number of seedlings is less, but the flowering will be more, its leaf color is also light; such as growing in the less sunshine, and the soil is loose and fertile, the air humidity is high, the orchid seedlings are tall, the seedlings are stout and many, the leaves are dark green and glossy, but the flowering is not much, and the orchid generally blooms more after going down the hill.

According to the growth characteristics of the cold orchid, in order to plant the cold orchid well, the key is to imitate the conditions of its native place to introduce and domesticate and breed, pay attention to the following aspects:

First, the cultivation principle: to raise the cold orchid down the mountain, the key is to cultivate a good root. Because the downhill orchid has many broken roots, if it is cultivated like other orchids, it will rot and dry to death. Cold orchid root is few and slender, the leaf is tall, this is its special case, but as long as it is treated separately on the plant material, it will certainly be able to raise it well. Down the mountain cold orchid root first, by domesticating its root, let its root long thick, short, multi-bifurcated, its orchid root is strong, its seedling is naturally easy to raise. Only with thick roots can seedlings be propagated. Its accomplishment at that time is to use loose and moisturizing coarse plant material, plus native rotten leaf soil to adjust and plant, without fertilization. The plant material is clean, fertilizer-free and toxin-free, and the coarse plant material is breathable and easy to root.

Second, plant material selection: only Yifeng, red brick slag is fired from red loam, not hard, slightly acidic. Coarse river sand, which is made of 30%, 40% shale, contains water and moisturizes. Shale fragments (schist) it can absorb water and drain water. The above materials must be strictly sterilized at high temperature, divided into large, medium and small particles (its specifications: big 10mi 20mm, medium 5mi 10mm, small 2mi 5mm). After sifting, they are bagged and set aside.

Third, the proportion of plant materials: ① red brick slag 70%, rotten leaf soil 25%, Reed ash or plant ash 5%. ② coarse river sand 65%, rotten leaf soil 35%. ③ shale is 80% broken and rotten leaf soil is 20%. In addition to coarse materials reserved for the bottom of the basin, small and medium materials should be prepared separately.

Fourth, orchid basin selection: orchid pots should be disinfected and sterilized before planting, orchid pots should be breathable and moisturizing deep foot mud pots, and non-hole orchid pots should be drilled. The pots should be larger, the pots are good at moisturizing, and they can also be planted. Orchids are generally planted regardless of the size of the pots, because the cymbidium is easy to blossom, and the varieties are identified and then planted separately, and the old Reed head can be used to cultivate directional seedlings and improve the seedling rate.

Fifth, mix and plant: mix the thick and thin plant materials separately, mix well, add the right amount of clean natural water, and then mix well until the soil is wet. Orchid planting materials are first used to cover the bottom, then use medium and coarse grains to plant roots, and small particles to plant Reed head cover, after planting, there is no need to pour fixed root water. Wait for the basin soil to dry before pouring through the water, and then put it in a cool place after planting for 20 days to a month before turning to normal management. Spray on the leaves once a day in winter and spring, spray in the morning, and spray leaf water twice a day in summer and autumn. When spraying water, be careful not to spray into the basin soil, lest the basin soil is too wet to cause rotten roots.

6. Newly planted moisturizing: cold orchid has small and long roots, cut off many roots down the hill, cannot supply water and distribute nutrients after new planting, and its leaves are large. Some cold orchids are about one meter high and more than 20 millimeters wide, so they should maintain leaf humidity and air humidity after planting. According to the air humidity of the orchid shed, 65% of the humidity should be maintained during the day and not less than 80% at night. Spray pipes or humidifiers can be added in the shed to compensate for humidity.

7. Promoting the growth of new roots: cold orchids are generally not fertilized when they are first planted in order to avoid rotting roots. after 50 days of planting, they can be sprayed on both sides of their leaves with a "king of orchid fungus" of 600 and 800 times, preferably three times a month, and in the afternoon, in order to promote it to grow new roots. Grass can generally blossom after cultivation, pay attention to inter-flowers in maintenance, and remove the excess flowers as soon as they are exposed; for those who need to identify varieties, it is only necessary to choose a strong flower to reduce unnecessary consumption and affect the germination and flowering of the following year. After flowering, use 500 times liquid of orchid king to irrigate 2Mel for 3 times in early spring, or use "national orchid germination agent".

Eighth, disease prevention and pest control: disease prevention and pest control should be based on the principle of "giving priority to prevention and supplemented by drugs". When coming down the mountain, bluegrass usually carries diseases and insects, especially shell insects appear on the back of leaves, so it is necessary to strictly clean, disinfect, disinfect and kill insects before planting, so as to prevent diseases and pests from harming and affecting reproduction in the future. In the process of treatment, if the orchid seedlings can be killed with drugs, a small amount can be mashed with garlic and mixed with a little edible rice vinegar, wipe the positive and negative sides of the orchid leaves with cloth juice, and remove the diseases and insects on the leaf beetles at the same time. Using organic matter to get rid of diseases is a good way to kill many birds with one stone. It is non-toxic, good at killing insects and sterilization, and can also make orchid leaves shine.

It is worth noting that when the temperature is too high, growing grass and spraying more pesticides on seedlings will affect their growth and seedling growth. Some orchids say that my orchids do not sprout, and their seedlings do not grow. What is the reason? They do not realize that it is the consequence of improper maintenance. In plants, like people, improper use of drugs is counterproductive. Our commonly used insecticidal and sterilized pesticides contain many chemical elements that are harmful to plant growth, such as the frequent use of copper preparations for orchid leaves, especially in high temperature periods, which usually lead to problems such as burning orchid leaves and leaf tips. In addition, it may also lead to root growth disorders and absorption and transport dysfunction, and affect the balanced growth of the whole plant, resulting in the problem of little or no seedling emergence. So please Lanyou or give priority to prevention, medication as a supplement, do not use a drug for a long time.
