How to cultivate Jian Orchid Culture methods and matters needing attention

There are many varieties of orchids, and Jianlan is one of them. Jianlan's leaves are broad and graceful, especially when they are in bloom, the flowers are very beautiful and are loved and sought after by everyone. Many people like Jianlan, but do not know much about its maintenance methods. The following editor will analyze its breeding and maintenance skills in detail.

How to raise Jian Lan

Jian Lanxi warm, humid and semi-shady environment, poor cold tolerance, overwintering temperature of not less than 3 ℃, afraid of direct light, not resistant to waterlogging and drought, suitable for loose, fertile and well-drained rotten leaves

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.

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.

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.

Culture methods and points for attention of Jian Orchid

1. Lighting requirements

Jianlan likes sufficient scattered light and does not like direct light. It needs about 70% shading in summer and autumn and 30% shading in winter and spring. Home breeding can be shaded by doors and windows at home.

In winter and spring, when the temperature is below 10 ℃, it can shine all day without shading, so as to promote the germination of Jian orchid and enhance the disease resistance of the plant.

2. Watering method

Watering Jianlan must grasp the principle of seeing dry and wet, and watering must be thoroughly watered.

Before watering to observe whether the orchid basin needs water, touch the blue soil with your hand, do not stick to the hand, or the basin soil surface appears white, should be watered in time.

When watering, it is necessary to ensure that the whole basin of soil is evenly wetted and the rotten roots are evenly distributed. You can also use the method of soaking the basin to build an orchid in the whole basin anyway, so that the water seeps into the basin from the bottom of the basin.

3. Fertilization method

Jianlan fertilization usually chooses agricultural compound fertilizer, 3-5 grains per pot, pay attention to the grain calculation can not apply too much fertilizer, in order to avoid rotting roots. Fertilizer should not be too close to the rotten roots. after applying fertilizer, cover it with blue soil and water it the next day.

When spraying water, you can add a small amount of potassium dihydrogen phosphate to it. The root of Jianlan has rhizobium, which can basically meet the demand of nitrogen element and reduce the content of nitrogen element in the process of fertilization.

4. Points for attention

The most suitable temperature for the growth of Jian orchid is 15: 23 ℃. When planting indoors, pay attention to control the temperature, not stuffy, not cool. The temperature of winter dormancy in Jianlan is controlled at 012 ℃, so that it will blossom more beautifully in the coming year.

When the summer temperature is high, it is necessary to cool down properly, ventilate in time, reduce watering when the temperature is above 35 ℃, keep the basin soil relatively dry, and maintain normally after the temperature rises.

Growth habits of Jian Lan

Jianlan originally grew in the hillside and valley walls of deep mountains and valleys, sloping slopes and sparse mountain grass. Sometimes it also grows on the cliffs by the mountains and streams.

Jian Lan likes the cool environment, likes moist, avoid dry, avoid direct sunlight, the most suitable temperature for growth is 15: 30 ℃, more than 35 ℃, less than 5 ℃, growth stagnation, there may be serious poor growth. If the temperature is high and exposed to the sun, the leaves are easy to burn, and if the temperature is low and does not move to the house in time, it is easy to get frostbite.

Jian Lan is a fleshy root, suitable to grow in humus-rich soil, good drainage, soil is slightly acidic, rich in iron, often loose soil is conducive to the growth of Jian Lan.

What if the leaves of Jianlan turn yellow?

Found that the soil is uncomfortable, immediately change the soil, you can choose a professional orchid culture soil, regardless of permeability or pH are more suitable. Try not to use the soil dug back directly from the outside, which is not very permeable.

In daily maintenance, put the orchid basin in a place with bright light, which can shine all day in spring and winter without shade. In summer and autumn, avoid the noon sun and shade properly.

When plants are found to be infected with diseases and insect pests, they should be dealt with in time. When rotting the roots, remove the plant from the pot, clean up the rotten parts, soak in the sterilized wild seeds for 20-30 minutes, dry and replant. If scale insects appear on the leaves, 1000 times of omethoate can be used if the insecticide is sprayed in time.

Through the above content, I believe you have a certain understanding of Jianlan's culture technology! Jianlan has high ornamental value and rich aroma, which is loved by flower friends, but Jianlan is more delicate and precious and needs careful maintenance, so you must understand its breeding method before you want to breed Jianlan.
