Nursing management of planting cold orchid

temperature

The cuticle and cell wall of the plant are relatively thin, so it likes warm winter and cool summer climate. It is afraid of cold and heat, and is particularly sensitive to low temperatures, so if a cold wind suddenly blows in cold weather, it should be done well in cold weather, otherwise it will cause the planting of cold orchid dead seedlings.

illumination

General wild cold orchid growth in hybrid forest, is rarely direct to the sun, so cold orchid is shade-loving, can not be strong against the sun, so that it can grow better.

fertilizer

The principle of cold orchid fertilization is to fertilize frequently, but to apply a little thin. Cold orchids are grown on native humus soil, which is fertile in the first year and does not require fertilization, but then fertilization begins.

Then we also understand about the selection of cold orchid pots, should be based on the shape and size of cold orchid selection, in addition to the color is also best to choose black. In addition, Xiaobian also introduced the cultivation and maintenance management of cold orchid today, so if friends cultivate cold orchid, they must pay attention to these items, so that cold orchid can grow healthier!

How to choose wild orchids

Orchid is a unique style of flowers, its ornamental value is very high. Orchids elegant colors, which are mostly green, yellow green, but especially those who are rare, the so-called wild orchids refer to survival in the natural environment; if you need to introduce wild orchids, how to raise wild orchids?

How to raise wild orchids?

Orchids from wild to domesticated, due to changes in the ecological environment, in the cultivation of certain methods should be taken to gradually change its original wild habits, adapt to new growth conditions.

1. Care before planting. Wild orchids that have just been collected or bought should be placed in a cool place in time to avoid burning out. If it is not planted in a pot for the time being, it can be laid flat on the ground, temporarily buried with wet sand and moist soil, and sprayed appropriately on the leaves when it is dry (to the extent that the orchid leaves do not drip).

II. Impurity removal and disinfection. Trim the plants, rotten empty roots and leaves infected with diseases and insect pests on the false bulbs, wash them with clean water, dry them, and then sprinkle the whole grass with 0.2% potassium permanganate or "zineb","carbendazim" and "topzin", and plant them after drying

3. Preparation of basin soil. Basin soil to mountain base soil, bamboo mud, mountain red soil, mountain depression gray black topsoil is good, but also a small amount of mixed use of river sand. If can pass steam, insolation of sunshine disinfects better.

4. Careful cultivation. New wild orchids should be placed indoors for maintenance until the new roots grow to 5~10 cm before they can leave the room. Especially in winter and early spring, it should be maintained indoors for a period of time, which is the key to survival. In addition, attention should be paid to temperature control, ventilation, moisture, room temperature should be slightly lower (3℃~8℃ is appropriate); spray water mist and open windows in due time to keep indoor air fresh. By simulating sunlight, it can obtain energy for photosynthesis, so as to promote recovery and growth. Each 20 square meter room can be illuminated by a 40W fluorescent lamp and two 3W red fluorescent lamps for 5 hours a day.

5. External supplies. Wild orchid seedlings after collection, transportation, planting pruning, the appearance of scars, in essence, is a semi-dehydrated state. In order to promote its recovery growth, it can be diluted with 1200~1500 times of potassium dihydrogen phosphate solution and 250 times of rice vinegar solution every week or added with 100~200 micrograms of B12 per 25 jin of fertilizer water, 20 grams of urea spray, and topdressing on the leaves. Cut off dead leaves and kill bacteria and insects in time. When the sprouts grow to 5 - 10 cm, they can be managed as mature grass.

How to choose wild orchids?

1. The seedlings are delicate: orchids are foliage and flowering plants. When selecting orchids, pay attention to the delicate seedlings. Leaves can not have black spots, nor can there be yellow leaves, which is a sign of disease orchid.

2. The roots are full and clean: raise the roots first. When selecting orchids, pay attention to the uniform color on the root system (uneven proof that the orchid root has lesions), check whether the orchid has empty roots (a small amount can be tolerated, may be caused by too little watering), rotten roots (it is best not to choose such orchids). After meeting the above points, if there is a crystal "crystal head" on the orchid root, such orchids are healthier.

3. Regular shops: For many novices, this article is more important than the previous ones. Because the orchid market is an information asymmetric market. Should choose a good reputation of the store to buy, such a store price will be more expensive, but the quality of seedlings can be guaranteed.

4. Take off the pot to buy orchids: Orchids are different from most other flowers in the sale. Most orchids are sold off the pot. If there is a peddler selling orchids, be sure to let the peddler take the seedlings out of the pot and observe the health of the orchids.

Wild orchid collection methods:

The collection of grass is the first step of domestication of wild orchids. To collect grass, we must first make preparations, including wild orchid resource investigation, tools and equipment, and preparation of postharvest cultivation sites. Orchids grow mostly in the forest, ditch edge or secondary forest tall grass, a few can also be in the fog around the top. These places are warmer and shade levels range from 40 to 50 per cent. Woodlands that are too dark or have too much direct sunlight are less distributed. Cymbidium is generally distributed at an altitude of 650 to 1800 meters, Cymbidium is distributed at an altitude of 1200 to 1300 meters, Cymbidium is distributed at an altitude of 700 to 2000 meters, Cymbidium is distributed at an altitude of 900 to 1300 meters, Lagotis is distributed at an altitude of 500 to 1500 meters, and Cymbidium is distributed at an altitude of 200 to 1200 meters. The second is to choose the appropriate collection time. Generally, it is ideal to collect grass from February to April every year, which is conducive to the survival of grass cultivation. In addition, autumn can also be collected, especially autumn flowering varieties, can reduce the workload of collection and cultivation, but also conducive to the protection of orchid resources.

When harvesting, if the soil is soft, you can pull it up from under the plant with both hands, but do not hurt the root system. Because orchid root system distributes wider, had better dig loose the soil around first with scythe, remove the weed around hind dig again. After pulling up, carefully clean the soil, wrap the plants together with fallen leaves with newspapers, put them into plastic bags to prevent the roots from drying, and record the habitat conditions of orchid grass, especially altitude, slope, soil, shade, humidity, etc., so as to facilitate domestication and cultivation. Excavated orchid grass should pay attention to moisture, timely transport cultivation, prevent drying, but must not sprinkle water on roots and leaves, let alone soak orchids in water, resulting in yellow leaves, withered orchid buds, dry roots, resulting in plant death. For the collected exotic species, they should be packed separately and carefully protected. They must not be mixed with other orchid plants to avoid accidental damage or even loss.

At the same time, when collecting orchid grass, attention should be paid to protecting the resources. We must not sweep them away and dig them out at one time. Instead, we should consciously keep some large plants on ridges, cliff mouths, tuyere or high places to allow them to bloom so as to facilitate their reproduction and offspring.

Summary: How to raise wild orchids Xiaobian introduced here, choose the best mining season around the Qingming Festival every year is the best season for wild orchid mining, too early or too late should not be_mountain mining. Clever watering wild orchids after the basin, to implement the six-word watering method, namely: spring and winter dry, summer and autumn wet. Specifically, spring and winter to keep the basin soil dry humidity is too easy to make orchid rotten roots die. Summer and autumn to keep the basin soil moist for a long time, and
