Turn: some experience of raising orchids on the roof

Growing orchids and raising orchids is a kind of elegant artistic enjoyment. For the middle-aged and elderly, they can cultivate themselves, enrich their amateur spiritual and cultural life, and benefit their physical and mental health. In 1989, I used the balcony of my residence on the 6th floor to grow more than 20 pots of orchids and orchids, which grew better due to careful maintenance. After several years of exploration and practice, we have initially mastered the technology of growing orchids and cultivating orchids, and greatly enhanced our interest in cultivating orchids. In 1992, an orchid shed with an area of more than 90 square meters was built by using the roof platform, and more than 400 pots of orchids were planted. A military flag. The global lotus top. Yu Meisu. I am a butterfly. Great wealth and nobility. Four happy butterflies. Song Mei. Wang Zi. Dragon character. Go down the mountain plum. Butterfly flowers. There are more than 100 varieties such as Yunnan lotus petal orchid. Among them, Sijilan has plum. Butterfly. Lotus. There are more than 20 varieties of Qihua, including Huilan Chengmei. Zheng Xiaohe. Nanyang plum. Yong Yan. Old words are dyed. A big grade. Close the top. And so on. The growth is generally good, the orchid leaves are green and gratifying, few spots or scorched tips are found, there are basically no diseases and insect pests, and there are more flowers, which are generally praised by orchid friends. According to my experience, in order to cultivate orchids, the most important thing is to create a suitable growth environment for the growth and development of orchids. Jiaojiang is located in the central coast of Zhejiang Province, is the central city of Taizhou, densely populated, economic prosperity, is a new port city. It belongs to the mid-subtropical marine monsoon climate, with an annual average temperature of 17 ℃, an extremely high temperature of 38.1 ℃, an extremely low temperature of 7.1 ℃, an annual range of 21.8℃, an annual average precipitation of 1519.9 mm, an annual average evaporation of 1360.4 mm and an annual average relative humidity of 82%. Because it is located in the coast and the wind is strong, the maximum wind speed under the influence of the typhoon is more than 45 meters per second. Generally speaking, the climatic conditions of Jiaojiang are basically suitable for the growth of orchids. However, in raising orchids on the roof, factors such as strong wind, large evaporation, strong light in summer and autumn, and sharp temperature changes between day and night must be taken into account. Orchids should be based on the characteristics of "happy sun and summer, wind and cold, rain and wet, dry and dry, soil and thick, fat and turbid, shade and dust, gas and smoke, quiet, clustering and leaving mother, cultivation and arrogance". I built it on the roof platform to keep out the wind. Take shelter from the rain. An orchid shed for concealment and proper adjustment of temperature and humidity. The material is mainly flat glass and scrap steel, the cost is not high, and it is convenient and applicable. In the process of orchid maintenance, mainly do the following work: one. Proper daylighting. The orchid plant is a shade-loving plant. In the hot season, it is necessary to avoid the scorching sun. But there must be appropriate light to enhance photosynthesis, accelerate the growth of orchid plants, strengthen roots and leaves, promote flower bud development, blossom more and bloom well. Generally from late April to mid-October, due to the high temperature and strong sun, honeysuckle vines and wisteria are planted above and on the west side of the orchid shed to keep the shade and moisturizing. It is more appropriate to maintain 10-30% transmittance. From late October to early April of the following year, the temperature is not high and the sun is not strong, so there is no need for shade. However, honeysuckle vine and wisteria can just begin to fall under the sun, and green leaves will grow in late April next year to shade and moisturize, so it is more ideal to grow honeysuckle vine and wisteria. two。 Pay attention to ventilation. Proper ventilation can keep the air fresh in the orchid shed, which is beneficial to the growth of orchid plants and prevent the breeding of diseases and insect pests. In high temperature weather, opening the orchid shed with proper ventilation can also adjust the air temperature and prevent the orchid plant growth from being too high. three。 Maintain proper air humidity. The ancients said that "dry orchid and wet chrysanthemum". Orchid is fleshy root, plant material (generally refers to soil) must be well ventilated and permeable to prevent stagnant water. Stagnant water for too long will reduce the air in the plant material, affect the physiological activities of Langen, and make the root system mildew. Therefore, the moisture content of plant material should not be too much, but the requirement of air humidity is higher. If the air is too dry, it will affect the growth of orchid plants. Therefore, when the air is dry and bathing, it is necessary to take spray and other methods to increase the air humidity. The air humidity should be kept at about 75%. four。 Adjust the temperature. The most suitable temperature for the growth of Cymbidium is between 15 ℃ and 28 ℃. When the summer temperature is higher than 32 ℃, the orchid shed should be ventilated. Spray and ground water spray and other methods to reduce humidity. If there is a low temperature below 0 ℃ in winter, the temperature should be increased properly in the orchid shed. Such as hanging a few electric lights in the orchid shed and so on. I use an electric kettle to boil water in the orchid shed, which can also have a warming effect. five。 Prevent all kinds of pollution. Raising orchids on the roof will inevitably be polluted by pollutants such as smoke and dust. Generally, water can be used to wash leaves, or drug prevention and treatment. My orchid shed is built on the roof of the sixth floor, with four glass windows and an open orchid shed on the top, which can be opened by rain and dew at night, and the windward windows are not opened or less opened. Pollution can be avoided and prevented. The above is only my preliminary experience of raising orchids on the roof, and I need to continue to practice and explore.
