How to cultivate soil for orchid farming? What soil is used to cultivate orchids?

Since ancient times, the people of our country love orchids, raise orchids, sing orchids, painting orchids, orchids have a noble and elegant symbol, and are called "four gentlemen" together with plum, bamboo, chrysanthemum, and are the best choice for many flower lovers to display the living room and decorate the study. The orchid is unpretentious, the leaf color is evergreen, the flowers are fragrant and far-reaching, and it has a very high ornamental value, not only that, but it is also very simple to breed. It is usually recommended to choose Gaolan pot as a pot, humus soil as pot soil, daily maintenance, only need to do regular fertilization in the growth period and flowering period, water on time to keep the soil moist, keep the temperature at 16 24, every 1 2 years to change the pot.

Next, we will talk about the cultivation method of orchids from the soil selection, fertilization method, watering method, temperature requirements and repotting requirements.

The soil for cultivating orchids should be loose and fertile, well-ventilated and slightly acidic, and it is recommended to use humus as the main soil, which can be humus soil or mountain forest humus.

In the long-term period of orchid peanuts, you can choose about 15 thin cake fertilizer water that has been rotted, or potassium dihydrogen phosphate fertilizer water added to urea fertilizer water, and apply it once every 15 20 days; Before flowering to flowering stage, potassium dihydrogen phosphate or plant ash water can be sprayed 2 or 3 times to the foliar surface to promote the development of roots, stems and flowers. Be careful not to apply unrotted fertilizer to avoid root rot.

Orchids can be watered according to the season, every 2 3 days in spring and autumn; In summer, when the orchid is in peak season, you can water it 1 or 2 times a day, and spray a little water on the leaf surface at the same time to increase the air humidity and promote the growth and development of the orchid. In addition, orchids also have requirements for watering water, it is better to choose rainwater, if it is tap water needs to be left for 2 to 3 days before use. The suitable temperature for the growth of orchids is 16 24, and if it is in a relatively low winter, it is advisable to keep the room temperature at about 10.

At the same time, ensure air circulation to avoid the orchid from exposure to the sun.

The pots for cultivating orchids can choose high orchid pots with thick tops and thin bottoms, with multiple drainage holes or drainage holes on the pot wall, and change the pot every one or two years.

Start by finding a small shovel, then use the shovel to turn over the soil, and finally press it a little tighter.

The level of humus content in the soil directly determines the amount of soil nutrients, and the growth of orchids has high requirements for soil nutrients, so it is necessary to choose humus-rich soil, so as to ensure the nutrients required for its growth.

The first type: rapeseed cake, farmhouse fertilizer, sandy soil 1, soil 1, dried leaves 2

The second type: fermented pine bark: deer swamp soil: a small amount of peat = 5:1:1, plus 5 to 10 grams of high-quality granular fertilizer.

The principle of soil blending.

When cultivating orchids, the soil collocation generally needs to meet five points: the soil is acidic, the soil is rough, the nutrients are abundant and sufficient, the water is retained, and the soil is loose and breathable. Soils that can meet these requirements are more suitable for cultivating discredited orchids.

Soft planting material-based soil blending.

When arranging the soil, it is mainly soft. We should choose some plants that are more loose and breathable, such as humus, sawdust, coarse sand and so on. It can be used to prepare the soil for the cultivation of orchids.

Add 1 2 sawdust, 1 4 humus and coarse sand and stir well. This kind of soil has the characteristics of porous, breathable, moisturizing, and sufficient nutrients, which is conducive to the growth of orchids. It takes root quickly, the plant is stronger, and the flowers are more vigorous.

Soil blending based on hard planting material.

Hard planting materials can also be configured with soil suitable for orchid cultivation. The more common ones are pebbles, broken bricks, stone orchids, moss, tree bark, etc. With these plants, you can grow orchids.

In general, hard planting materials are used to arrange the soil, and it is difficult to master the use of fertilizer. It is best to add some soil to the soil to replenish nutrients. When configuring the soil, the planting material can be arranged in layers.

Large plants can be placed at the bottom of the pot, small and medium-sized plants can be placed in the middle, and a slightly finer field soil can be placed on the top layer.

To use slightly acidic loam soils rich in humus.

1. Relevant requirements.

1.Loose and breathable: first of all, of course, these two requirements so that it can breathe smoothly. In addition, its roots are able to develop normally.

2.Good drainage: The second one is about drainage. This is also important because this plant is very susceptible to waterlogging. If the drainage is not good, it will cause water accumulation, which can easily harm the plants.

3.Humus: This is nutritional. If it contains more nutrients, it will grow vigorously in the future.

4.Acidic: According to the characteristics of this plant, it does not like alkaline and prefers acidic ones. However, it doesn't need to be too acidic, and the pH is just 6 to 6.5.

2. Soil configuration method.

1.Yanglan: For this, the configuration method is relatively simple, just mix the decaying bark and soil, and each occupies half of the plan.

The first is a mixture of humus, red soil (wild or roadside), and river sand (or red sand) in a ratio of six to three to one. This method meets most of the requirements, such as aeration, drainage, and fertility. Second, it can be mixed with humus, red brick crumbs, river sand, and dried animal manure.

Sixty percent humus and 10 percent other than the others. This combination is more troublesome, but it will be relatively effective. There is a third method, which is simpler, just mix humus and sandy loam, half each.

However, be careful not to make it alkaline no matter which one you choose.

Extended Information] Orchid is an orchid plant that is widely distributed throughout China. China has cultivated orchids for more than 2,000 years, and has always regarded orchids as a symbol of nobility and elegance, and is one of the top ten famous flowers in China along with "plum, bamboo, and chrysanthemum", collectively known as the "Four Gentlemen". Orchids are generally epiphytic or terrestrial herbaceous, with several or more leaves, usually born at the base of the pseudobulb or on the lower nodes, two-rowed, ribbon-like or rarely inverted-lanceolate to narrowly elliptic, the base generally has a broad sheath and encloses the pseudobulb, and is jointed; The racemes have several or multiple flowers, and the colors are white, pure white, white-green, yellow-green, light yellow, light yellow-brown, yellow, red, blue, and purple.

It is best to raise orchids with miscanthus topsoil. This kind of topsoil is rich in nutrients humus soil, because it grows in the jungle all year round, and there are many dead branches and fallen leaves after years of accumulation and decay, so the nutrients are very rich. This kind of soil is loose, not cracked, and not compacted, and is used to grow orchids, the soil has good air permeability, and the rotten roots are not easy to rot.

This kind of soil contains a certain amount of humus and has an agglomerate structure, so the function of water and fertilizer retention is better. However, if friends want to take it, it is advisable to take the topsoil, the kind that is close to black in color, and the deep soil is not needed. After taking it back, expose it to the sun, disinfect and sterilize, clean up some impurities on the surface, and then use it in the pot.

Using an appropriate amount of miscanthus topsoil mixed with the mixed planting material, the root system of the orchid raised is not easy to blacken, and the new shoots will be relatively stout, and the leaves are thick and fat.

There must be soil to plant orchid, solid soil is indispensable in the orchid soil, and the orchid soil must be prepared, and the soil is mixed with Youlan. The preparation of blue soil should be mainly based on humus soil, with red clay as the key, and then prepared with other materials. The basic principle is that the composition of fine-leaved orchids and humus soil is heavier, and the composition of broad-leaved orchids and solid soil is heavier.

The tips for the suitable preparation of blue soil are as follows:

Humus soil is prepared with laterite soil and mountain base soil. Saprophyllum accounts for 60 percent, red soil, mountain base soil each accounts for 2 percent, humus and laterite are prepared, humus soil accounts for 70 percent, red soil accounts for 30 percent.

Leaf humus is prepared with field soil and garden soil. Humus soil accounts for 50 percent, and field soil and garden soil account for 50 percent. Because the field soil and garden soil are cooked soil, loose bubbles, the composition can be aggravated.

Humus soil is formulated with rotten wood soil. Rotten wood mainly refers to two kinds of rotten oak wood and rotten fir wood. It is advisable to mix and prepare. It can also be formulated individually. This kind of preparation, must be added soil, red soil is preferred, field soil, garden soil, mountain foundation soil optional. The addition of the composition should be more than 20%.

Humus soil is prepared with sandy soil, sandy soil can be used, and sea sand can be used. River sand, stone sand. Choose coarse sand and use less fine sand. Humus soil accounts for 6 to 70 percent, and sandy soil accounts for 4 or 3 percent.

The preparation of blue soil can be prepared in advance, and it can be prepared temporarily, and the preparation in advance is better than the temporary preparation. When comparing, mix the materials together in proportion with an iron basin or bucket basin, pour an appropriate amount of water to make the prepared soil moisture, and then put it in a bag to cover it, so that the soil is fully harmonious, and at the same time eliminate the insect pests in the soil.

Slightly acidic soil, orchids are suitable for cultivation with slightly acidic soil, when cultivating, the pH value of the soil is best between, which is conducive to better growth of plants, after cultivation, you need to provide sunlight to orchids, so that the plants can absorb enough light to grow more robust, and you also need to provide water for orchids, and keep the soil moist when watering.

The soil mixing method of orchid is actually very simple, usually you can use humus soil and coarse sand to mix it as a substrate in the ratio of 7:3, or you can use garden soil, humus soil, and sawdust according to 4:3:

The ratio of 2 is mixed as a substrate, and its practical garden soil, coconut brick, and orchid stone are mixed as a substrate according to the ratio of 4:4:2, which is also very good, which is conducive to the better growth of orchids.

1. Humus soil

Orchid does not have high requirements for soil, it has many ways to mix soil, usually can be used humus soil, which can be added in an appropriate amount of coarse sand, etc., mixed in accordance with the ratio of 7:3, and can also add well-rotted organic fertilizer to improve soil fertility.

2. Soft substrate

Orchids generally grow well in a loose, breathable and water-retaining substrate, and can also make orchids bloom beautiful flowers, we can use garden soil, humus soil, wood chips (bark) in a ratio of 4:3:2 mixing, which is conducive to the growth of orchid roots.

3. Mixed soil

Usually in the cultivation of orchids, you need to use the right size of the container to breed, can be used mud pots, purple sand pots and plastic pots and other containers, so how to breed orchids with soil, can be used ordinary garden soil, coconut bricks, orchid stone in accordance with the ratio of 4:4:2 mixing, adding the right amount of nutrient soil is also very good.

In fact, orchids can also be used as the main soil with humus and garden soil, which can be added with pebbles, sediment, orchid stones, coconut bricks, sawdust and other substrates, so that the mixed soil is very suitable for breeding, which can make the orchid grow lush and have more ornamental value.
