Key points of maintenance and management of Jianlan

Jian Lan is a terrestrial plant and can also be potted. The difficulty of cultivation and management of Jianlan is not high, but because the popularization rate of Jianlan is not high, there is not much introduction to the cultivation and maintenance of Jianlan. The editor has sorted out the relevant information about the maintenance and management of Jianlan for you. Friends in need can understand it together.

Jian Lan

1. The preparation of matrix. The function of matrix is to fix plant and conserve water, but the content of fertilizer is not important. To choose a matrix, you must first understand its characteristics. The calcined mud pond soil, perlite and volcanic soil are all very suitable to be its medium, which can be fully soaked before use to make it fully absorb water. Organic matter such as rice husk, peanut shell and bark can also be used as a medium, because it contains fertilizer, it must be mixed with other inorganic substances, but the ratio is not too high, generally not more than 30%, and the effect is ideal after carbonization treatment. The fine stone in the riverbed, the hard soil block or the gravel of the sand factory is also a very ideal medium, not only good drainage, high water content, cheap, but the disadvantage is too heavy, generally mixed with organic media.

2. Cultivation facilities. Orchid planting can be divided into courtyard planting and large field planting. General family orchid can choose balcony or rooftop, can also build a shed in the windowsill, with rough texture, no upper shaft, porous edge and bottom, orchid pot with basin feet is better.

3. Growing environment. The original growth environment of Jianlan is eastward or southward near the original jungle at the top of the mountain with a little sunshine, abundant rainfall in summer, and morning and dusk fog to supply its growth in dry winter, if calculated in terms of shading rate, shading with 80% plastic net can achieve the same effect. Because its vegetative growth needs high temperature, reproductive growth depends on the temperature difference between day and night, and the best growth temperature is 15: 30 ℃.

4. Water and fertilizer management. Jianlan needs the same nutrients as other plants, except for carbohydrates needed for photosynthesis, nitrogen, phosphorus, potassium, sulfur, magnesium, calcium and other trace elements are indispensable. Jian Lan has a strong reproduction rate and high flowering rate, which is very suitable for cultivation in the natural environment. Fertilizer loss is serious without rain shelter facilities. Long-acting solid fertilizer is suitable for base fertilizer, and topdressing is suitable for quick-acting liquid fertilizer.

Quick-acting organic liquid fertilizer, that is, the latest biotechnology sugar and vinegar liquid and microbial organic liquid fertilizer, is very convenient to use, directly diluted and sprayed with water, but also can inhibit diseases and insect pests, quick-acting chemical fertilizer, such as Huabao, Batek Fertilizer, Yifei Dan, urea and so on. The best way to use liquid fertilizer is in the early morning, because most of the liquid fertilizer is quick-acting fertilizer, which is not absorbed by plants without photosynthesis. Don't water before fertilizing, otherwise there will be more losses than absorbers. No matter what fertilizer is applied, it should be applied on the edge of the basin and should not be applied near the orchid head or orchid head, so as not to burn and evolve into soft rot. In case fertilizer falls on the orchid, it should be flushed with clean water in time.

It is better to water Rain Water and tap water, morning and evening in summer and autumn, noon in winter and spring, more water in peak growing season, less watering in winter and spring dormant period, wet basin soil and dry soil. Watering method, not only the basin bottom to water, the medium needs to be completely drenched. Uneven drying and wetting are prone to mildew and root rot. Watering times, depending on the basin size, medium water retention, humidity, light intensity, temperature and ventilation to consider.

Four key points of maintenance technology of Jianlan

China Garden Network, September 17: Jianlan, also known as Sijilan, Xia Hui, Qiu Lan, Qiu Hui, Jianhui, Xionglan, Junhelan and so on, is mainly distributed in Taiwan, Fujian, Zhejiang, Anhui, Jiangxi, Hainan, Guangdong, Guangxi, Hunan, Hubei, Sichuan, Yunnan, Guizhou and other provinces. Jianlan has strong adaptability and can blossom and give off fragrance in all parts of our country. Even so, the daily maintenance of Jianlan still needs to pay attention to four aspects.

First, there should be plenty of light. Wild Jian orchids are mostly born in sunny places along forest slopes or under sparse forests at the top of the mountain. Therefore, Jianlan is more like the orchid species with sufficient light, and daily maintenance can put it in the place where the orchid shelf is easy to see light, with as little shade as possible, otherwise it is not easy to blossom, and some varieties of orchid need to be exposed to the sun in order to blossom.

Second, fertilizing should be relatively diligent. Most of Jian Orchid can blossom twice a year, the florescence is from July to October, usually blooming twice, about a month apart; the early flowering stage is in early July, the full flowering period is in mid-July; the initial flowering stage of the second flowering is in early August, and the middle flowering stage is full flowering stage; in addition, many flowers with one arrow consume a lot of nutrients. Therefore, in the maintenance should be in line with the principle of frequent application of thin fertilizer, fertilization should be relatively diligent, so that Jianlan can grow healthily and blossom in place.

Third, pay attention to the prevention of insect pests when the flowers are in bloom. The flowering season of Jianlan is generally in the high temperature season from July to September, which is most likely to occur when thrips and aphids invade buds and flowers, resulting in short buds, browning and withering, flowers being gnawed beyond recognition and seriously affecting ornamental. Therefore, during the period from stamen to full bloom, Jianlan should give priority to prevention, combine prevention and control, and spray drugs in time to avoid suffering from insect pests.

Fourth, pay attention to anti-freezing. Most of the wild Jian orchids grow in the subtropical areas with warm and humid climate to the south of the Yangtze River, and there are few low temperatures below 0 ℃, so they are afraid of freezing. Cultivation in the north of the Yangtze River should be kept in a closed orchid room in winter, and the temperature should not be lower than 0 ℃, otherwise it is easy to freeze.
