Is it OK to grow white orchids in Northeast peat?

Preparation of white orchid potting soil: 1. Saprophyllum + garden soil (or pond soil) + river sand, the ratio is garden soil + peat soil + river sand, and the ratio is nutrient soil + river sand, with a ratio of 8:2. Raising white orchids in the north also requires the addition of ferrous sulfate to increase the acidity of the soil.

Summary. Hello, before using charcoal to plant orchids, be sure to soak the charcoal for a period of time, so that you can remove the dust and impurities inside, which is conducive to the growth of orchids after planting. Charcoal has good water absorption and air permeability, and also has very good drainage and moisturizing properties, the main component of its material is carbon, so adding an appropriate amount of charcoal to the soil can be used as planting material and fertilizer, which is of great benefit to the growth of orchids and other flowers.

I asked about peaty soil.

It also needs to be soaked.

Do not soak too wet to prevent root rot.

If it is in the north, because the water is relatively alkaline, if it is used regularly, the soil will be alkalized, so it is best to use rainwater or add some ferrous sulfate to the water, but because rainwater and snow are not easy to store, you can use tap water at ordinary times, and generally give it ferrous sulfate once for about ten days, which can help it not to yellow.

Changing the soil for it is the same as pruning it, it is once every 2 years, and each time you change the soil for it, you have to use a larger pot than before. It can be done in the spring when the shed is out. After disinfecting the new pot, spread some broken tiles at the bottom of the pot as a drainage layer, then spread about three centimeters of soil on it, put some horseshoe pieces, use it as base fertilizer, and then spread a layer of soil, take the tree out of the original pot, remove the dead and old roots, plant it in and press the soil tightly, and then water it thoroughly.

Its germination ability is relatively low, so its branches are generally not pruned, but it is very necessary to remove branches that have withered or been eroded by diseases and insects. It is also important to remove some of the leaves moderately after the bud has formed, which allows the flowers to grow larger and longer.

Peat soil can be used to grow orchids. Peat soil contains a lot of nutrients, and when grown, it can generally provide the right amount of nutrients for the growth of orchids. However, it is not allowed to use only this material when using, otherwise there will be nutritional imbalance.

Advantages and disadvantages of peat soil orchids.

Advantages: Peat soil has good air permeability, so that the roots of orchids can breathe and absorb nutrients well. In addition, peat soil has good drought resistance, good waterlogging resistance, strong water permeability, and less root rot.

Disadvantages: Peat soil is generally imported, less domestically produced, and more expensive. It is generally formed by the natural decay of trees and grass.

How to grow orchids in peat soil.

1.Sterilization: Peat soil itself contains a lot of impurities, some of which will breed some bacteria and insect eggs in the natural process, so it needs to be disinfected or exposed to the sun before use.

2.Soil mixing: Peat soil cannot be used alone.

Generally, when planting orchids, they can be mixed with ceramsite, perlite, garden soil and other materials. This not only increases the permeability of the soil, but also provides a more complete source of nutrients.

60 percent can be blended with humus, 30 percent laterite (wild soil or roadside laterite), and 10 percent river sand (river sand from construction sites).

This ratio of soil aeration, water filtration, fertility, orchid growth is good, do not use alkaline soil (alkaline soil is the obvious feature of watering, and the color turns white after the soil is dry).

The soil requirements for orchids are loose, well-drained, and rich slightly acidic soil with humus. This is the ecological habit of orchids growing on the litter layer of the understory in ancient times.

Orchids are cultivated in the north, and it is better to have a neutral and acidic soil that contains a lot of humus, loose and well-drained. In the past, more from Shaoxing, Zhejiang and other places to collect and transport mud to cultivate precious varieties, in recent years, try the local production of peaty soil 3 into 1 into river sand, and mixed with some organic fertilizer (need to be stacked for a period of time), the growth is also better. The humus soil under the broad-leaved forest in the northern mountainous area, the humus soil made of the deciduous leaves of broad-leaved trees, and the culture soil containing 6 percent humus can be used to cultivate orchids.

Cultivation management orchid has a history of more than 2,000 years in China and has accumulated rich experience. Chunlan is a semi-negative plant, and the growth depends on maintenance and management. The cultivation site should be well ventilated, have shade facilities, and master the light.

Shade nets and film are commonly used to prevent rain and shade, and better shade is required in spring and summer, and sufficient sunlight is given in autumn and winter, which is conducive to the growth and flowering of roots and leaves. Avoid direct sunlight or exposure. Watering is the key to raising a good spring orchid, and the amount of watering depends on the temperature, the intensity of the light and the growth of the plant.

Generally speaking, in winter, when the temperature is low and the humidity is high, it is watered less, and in summer, the plants are growing vigorously and the temperature is high. However, in summer, it is necessary to avoid showers and use film to block the rain. Watering should be early in the morning.

Autumn rain is prone to black spot disease. In winter, it is better to water at noon on a sunny day. It is best to install automatic spraying facilities to increase air humidity, which is more beneficial to the growth and development of Chunlan.

The water used for orchids is generally rainwater and river water, and tap water must be used after entering the pool. Fertilization is necessary for Chunlan. Spring, summer and autumn, is the orchid growth period, can be more fertilization, from late March to late September, fertilization 1 time a week, the concentration should be light.

Orchids grow slowly in autumn and winter, so fertilizer should be applied less and once every half month. Spray a small amount of water after fertilization to prevent the fertilizer from staining the leaves. Fertilization must be done in the evening on sunny days, as there is a risk of root rot on cloudy days.

Generally, orchids are dormant in winter and do not need to be fertilized. During the growth period, granular compound fertilizer can also be used"Huiyou"15 15 30 potted flower special fertilizer. Due to poor ventilation and high humidity, Chunlan is prone to black spot and fungal diseases.

Black spot disease often damages new shoots, and in severe cases, the whole plant dies. In addition to strengthening ventilation and controlling air humidity, 600 times liquid spraying can be used with 65 dysen zinc wettable powder. Mycosis causes rhizome rot, which can be controlled by spraying 500 times of pentachloronitrobenzene powder.

During the cultivation process, if scale insects damage the leaves, they can be sprayed with 1000 times of 40 oxidized dimethoate EC.

Do you use peaty soil or plant ash to grow orchids? The materials used for planting orchids are varied, and the humus granular materials (soft planting materials) that are loose and breathable, absorb and drain well, and have certain nutritional value are usually used in daily operation, and some porous phytolites, stalactites, volcanic stones and artificial ceramsite, broken bricks, small stones, etc. (hard planting materials) that can play a hydrophobic role.

Among the soft planting materials that are often used, fermented and rotted bark blocks, rotten branches and leaves, peanut shells and many other humus materials are usually used. Many Lanyou will also often add and use some crushed charcoal particles, and generally rarely add and use plant ash. Because the plant ash is a powdery fine particle, it is easy to be discharged out of the pot with the water flow when watering, and it does not play much role in the hydrophobicity and air permeability of the cultivated planting material, so it is rarely used by orchid friends.

The peaty soil is a relatively loose and breathable, moderate particle size, and has very good nutrients. It is a good choice for planting materials when planting orchids. In particular, the peat-based particles screened from the peat-based soil are the first choice for orchid planting.

This granular material, which is screened from peaty soils, is more hydrophobic, breathable and nutritious in growing orchids. This granular peaty soil is better than powdered peaty soil in the cultivation of orchids. It can be used alone or with some other materials.

After planting, orchid seedlings are easier to pot, and the germination rate will be greatly improved.

In addition, it is relatively easy to master watering management. Therefore, when planting orchids, use peaty soil particles whenever possible. When using ordinary peaty soil, it is necessary to add some granular materials such as bark blocks, peanut shells, coconut shells, rotten branches and leaves, pebbles, ceramsite, red bricks, etc., so that the planting material is more nutritious and hydrophobic and breathable.

Plants and trees are gray and alkaline, and it is definitely not possible to plant orchids purely with plant ash. Grass ash has a certain role in the prevention and control of some orchid diseases. For example, white silk disease can be sprinkled with plant ash, and the effect is not bad.

The mechanism is that pathogens like slight acid, while plant ash is just the opposite, so it has a certain effect on pathogens.

Both materials look like burnt ash, but they are completely different. Peaty soil can be used to grow many things on its own, whereas it is impossible to grow living plants (including orchids, of course) with pure plant ash.

Grass ash is better, because plant ash is rich in nutrients, which is very helpful for the growth of orchids.

It is better to choose peaty soil, which is rich in organic matter, such as humic acid, and grass ash is mainly the ash left after combustion, mainly inorganic salts, especially potassium carbonate, which has a certain alkalineness, so when transplanting new seedlings, it is advisable to choose grass carb soil.

Grass ash, plant ash contains a large number of growth elements, the most abundant is potassium, generally containing 6 12% potassium, of which more than 90% is water-soluble, in the form of carbonate ((K co)); It is a kind of inorganic farm fertilizer with wide range, low cost, complete nutrients and obvious fertilizer efficiency.

Peaty soil, because planting orchids requires loose and breathable soil, so choosing peaty soil is more permeable and nutritious, which is conducive to the growth of orchids.

The whole process of orchid potting - the proportion of peaty soil and precautions.
