The author is an amateur orchid lover and has a soft spot for Han Lan. Recently, I read the editor of "Chinese Orchid" magazine and Professor Liu Qingyong of Lan Jie expert. "The cold blue should also be a little bit hot."
The Hanlan plant is slender and graceful, with a graceful, graceful and graceful appearance. Its colorful and varied colors have a long and clean fragrance. The beauty of all sorts of orchids is in one, and the spirit of all things is one. Why is it so difficult to enter ordinary homes with such elegant orchids? Why hasn't it been "hot" in the blue world? The reason for Professor Liu's analysis is: "Cultivated technology has not been solved."
This life is in the cold-blue production area. In recent years, thousands of pots have been planted in the coldland, and some knowledge of the cultivation of the cold-blue orchid is now known as the "Family Elements of the Coldland Blue." Beautiful Cymbidium adds spice to your life and brings you luck. It is also considered to be a "hot" point for the cold blue to warm up in the blue world!
First, choose a good plant material. Whether the planting material is suitable for the characteristics of orchids is conducive to the normal growth of orchids, and is the key to raising orchids. The author used the foundation stones, stone-planting stones, used clay, cents, broken bricks, and mixes with too many planting materials, and found that they were mixed with a certain amount of mountain mud (humus The soil grown in the soil mixture is the best, and the root system is not only well-developed, but also the seedling rate and flowering rate are higher than that of other plants. Therefore, it is concluded that the normal growth and flowering of Cymbidium require various nutrients, and that nutrients that are difficult to satisfy the growth needs of Cymbidium using various fertilization methods without soil cultivation can be supplied from the incorporated mountain mud. better. It is recommended to prove that the planting formula that is more suitable for cultivation of Cymbidium by several years of comparative experiments: 40% of pond-based stone or phytolith (also can be replaced with other hard-planted materials or river sand), and black rot (preferably black orchid of native orchids) 35% of the soil, 15% of bacteria or waste wood (sun exposure or disinfection) planted with edible fungi, and 10% of snake wood (or fern root instead).
Second, reasonable shade. The native forests of Cymbidium are dense with tall trees sheltering them from the sun and shade. Therefore, we also need to artificially create suitable lighting conditions for planting cyperus. Excessive light makes it easy to cause sunburn caused by sunburn. Excessive shading or long-term indoor exposure can affect the photosynthesis of orchids resulting in poor growth and difficulty in flowering. According to the author's practice, winter and spring with a layer of about 70% (fixed), summer and sunny day plus a layer of about 50% (active type) shade nets are most suitable for the growth of cold ash (overcast days can not cover). In short, under the premise of ensuring no burning of the blue leaves, sunlight is common enough, especially the morning light before 9:00 am is very beneficial to the growth and flowering of orchids.
Third, control watering. Strict control of watering, usually as far as possible basin soil moist without wet, dry but not dry is the key to raising a good cold blue. Many beginners raise orchids for fear of lack of water in orchids. When they are empty, they water the plants, resulting in too-bassed soil and orchid rotten roots. This is the main reason for the failure of most orchids to undergo orchid cultivation. The cultivar prepared with the above proportions was planted with cultivar cycads, which were usually watered once in 8-15 days in late spring, once in 4-6 days in sunny summer, once in 5-10 days in autumn, and often more than 20 days in winter and early spring. Even more than a month without watering. In order to facilitate the relatively unified management of large and small pots, I adopted a reasonable basin with the number of seedlings and the degree of development of the root system, that is, large pots and multiple seedlings, small pots and small seedlings, well-developed pots with large roots, and poor root pots. . Strong seedlings can also be used with weak seedlings, rare and famous products with the general species to accompany planting, this is consistent with the habit of orchids like poly culture, accumulation of blue bacteria conducive to growth, and can basically reach the same size of watering cycle. Pentu soil to see dry see wet, pouring that is poured, usually slightly dry as the principle, so raised the cold orchid root system developed, robust growth, rarely rot and root decay phenomenon.
Fourth, maintain the humidity, the humidity here refers to the air humidity. Chillland prefers a little dry earth and a high humidity environment. Therefore, planting cold and pleasant people to create 55% -75% of the daytime, no less than 80% relative humidity at night, can use humidifiers, automatic spray, hanging curtains, ground watering, set basin or basin humidification and other measures. The air is high in humidity and the chilly leaves are shiny and green, which grows well. It is easy to raise the top seedlings with full sealing tips. However, the humidity should be remembered to keep ventilation constantly.
Fifth, prevent pollution. Cymbidium leaves are long and thin, with many stomata and large air contact surfaces. Therefore, fresh air and no pollution are particularly necessary. Hanlanyuan stress avoids factories and workshops that have exhaust fumes and large amounts of dust nearby. Households should be kept away from smoke windows, range hoods, and air outlets of air conditioners as far as possible. At the same time, clean water with no pollution and moderate pH should be used. In other words, any person who feels fresh air, no smoke, little dust, no smell, and a well-ventilated environment is suitable for raising orchids. All people can drink water can be used for blue water. In addition, smoking in a blue room should be avoided as much as possible.
Six, scientific fertilization. Most Cymbidium pseudobulbs are relatively small and have limited nutrients for storage, coupled with easy flowering and large flowers with large flowers and consume more nutrients. Therefore, it is best to add a small amount of basal fertilizer when changing the pot. The author's experiment found that 1% of the pig manure mixed with fermented and sterilized fermented fermented grains is the most favorable for the growth and flowering of chilled ash. However, as soon as the grasses are just down the mountain, the newly acquired grasses and long-term weak seedlings that have been transported or mailed by long distances must not be rushed to fertilize, otherwise they will be harmed. In addition, potassium dihydrogen phosphate, blue fungus and other alternately used for foliar fertilizer, once every seven to ten days, new shoots can increase the amount of urea in the long term, the new seedlings sprayed two to three times high potassium fertilizer to promote pseudobulbs to increase. In order to make various nutrients evener, a thin organic fertilizer may be applied once a month from April to June and from September to October. However, it should be remembered that rather than being concentrated, it should be avoided.
Seven, pest control and disease prevention. To do a good job in Lanzhou sanitation, thoroughly eliminate insects, pathogens and sources of infection is the key to pest control and disease prevention. Diseased plants that are found to be seriously endangered and susceptible to mutual infection should be completely isolated or destroyed. Diseased leaves and dead leaves that are usually cut off should be burned. Secondly, the cultivation of chilly orchids must be potted, so that it is easier to manage than land, less pollution, less pests and diseases. Once again, timely spraying, generally from March to March in spring and fall from October to November is the peak period of pests and diseases. This period of time can alternately spray one time of anti-insecticides from ten days to half months, and the rest time can be once a month. Disease prevention can use thiophanate-methyl, mancozeb, carbendazim, chloramphenicol, diclofenac and other bactericidal drugs, insecticide can be used omethoate, rapid culling, ketosis, enemy killing, etc.
VIII. To cultivate a blue-green culture, you must be patient and must not be eager for quick success or instant benefits. Some of the new orchids who started to cultivate orchids lacked knowledge and understanding of the growth characteristics and laws of orchids and were anxious to achieve success. Or be overly affectionate and give orchids a little water whenever you have time. Today, I will not be able to look at Changxin Root, but tomorrow, we will put new plant materials on it, and toss the orchids to death. How can we grow well? In order to have more seedlings, there are also orchid friends who have divided the orchids too often. The result is that the longer they are weaker, the more they die. Some people are afraid of lack of orchids, fertilizer, frequent application of various fertilizers cause damage. These practices are contrary to the law of the growth of orchids, light is "see flowers in one year, see seedlings in two years, see pots in three years," heavy that short-term "destruction of the entire army." Orchids are human. You know her and love her. She naturally sprouts year after year and gives you generous rewards. Beloved, spoiled, or eager for success, is not allowed.
