It is better to use in situ soil than nutrient soil to maintain orchids, why?

Because the soil in situ is rich in a variety of active nutrients and microorganisms, it has enough nutrients for orchids.

Whether the orchid is used in situ soil or nutrient soil, it should not be used alone, some particles can be added, orchids have requirements for planting materials, and air permeability is the first.

Humus, perlite, peat soil is the mainstay.

Usually the substrate used to grow orchids is called planting material, which is soft and hard. Depending on the region and climate, the choice of planting material is also different. Soft planting materials are mainly humus, perlite and peat soil, which have high nutrition and strong water retention capacity, but they are easy to rot roots if the water volume is not well controlled.

Hard planting materials are mainly pine bark, coconut shells, peanut shells, etc., which have good drainage capacity, but fertilizer is also easy to lose. In general, hard planting materials are selected in hot and rainy areas, while soft planting materials are selected in dry and cold areas.

Orchid sowing method

Orchids are commonly propagated by dividing, sowing and tissue culture. Orchid seeds are very fine, there is only one incomplete embryo in the seed, the germination ability is very low, and the seed coat is not easy to absorb water, so it can not germinate by conventional sowing methods, so it is necessary to use orchid fungi or artificial medium to supply nutrients in order to germinate.

It is best to use the fruit that has not yet cracked for sowing, after the surface is sterilized with 75% alcohol, take out the seeds, soak them in 10% sodium hypochlorite for 5-10 minutes, take them out and rinse them with sterile water for 3 times to sow them in the culture flask containing the medium.

Then put it in the dark culture room, keep the temperature at about 25, and then move it to the light after germination to form the protocorm. From sowing to transplanting, it takes six months to a year. Tissue culture has been successful, and this method can be used to propagate where possible.

Those orchid friends who say that orchids don't need fertility to grow are probably going into a misunderstanding. The growth of any kind of plant is inseparable from fertilizer, but the difference in the amount of fertilizer elements, orchids are no exception. The fertility that orchids like is the organic matter after the decay of fallen leaves, pine needles, and rotten grass roots.

In this slightly muddy and sandy soil, there is a lot of humus flowing down from the mountains, which is rich in nutrients and comprehensive, long-lasting fertility, loose and breathable, not easy to compact, and will not burn roots.

To obtain such soil, we can go up the mountain to collect, mix the fallen leaves and the surface soil with water, put it into a plastic bag for closed fermentation, put it in a sunny place, it can be fermented in about 3-5 months, and the fermented humus can not be directly used to plant orchids, first of all, it must be thoroughly disinfected, so there are great requirements for orchid planting materials, the biggest feature is that it requires breathability and water permeability, can not accumulate water and rot roots, and it is best to ensure nutrition without water accumulation. Therefore, I am used to raising orchids with both soft and hard planting materials to ensure water permeability and nutrition at the same time.

Because the potting soil has good water holding capacity, there is no need to water frequently, and it is much easier for orchid farmers to water less, and the common soft planting materials are moss, bark, leaves, humus soil, peat, coconut peat, etc. Increasing the weight of the plant can make the orchid soil closely combined with the roots, and the planting material is on the light side, not because of watering, but because the orchid is crooked. Pine needles, the nutrient content of humus soil after the leaves are rotted is very high, and it can cultivate probiotics for orchid growth.

The red soil can no longer be used, and the vegetable soil of the fertile garden cannot be used, so I started with the soil, and it was all half-dead. Later, I will see **, and then practice, potted orchids are to drain water and breathe, pine bark, peanut shells, volcanic stone, and perlite may be the best in the south. This year I just changed the distribution, do not need to water so diligently, wait for next year to produce results, this planting material can improve the germination rate, is still experimenting with the results to come out to share with you, no matter what planting material is mainly breathable, drainage, nutritious on the line, novices can also raise big white roots.

Soil for planting orchids: moist, fertile, rich in a lot of humus, moderately and continuously moist, can not be directly exposed to light for a long time, there are many fallen leaves, rainwater does not accumulate, the soil is mostly sandy loam, acidic. Generally, you can go up the mountain to dig up trees and plant under the soil, or mix three parts of peat soil and one part of sandy soil, with an appropriate amount of fermented sawdust and cow dung.

If the soil is compacted, the drainage is not smooth, and the humus content is low, it will affect the normal growth and development of fleshy roots. or lack of adequate nutrients, or due to poor drainage affecting root respiration, or even causing root rot, the soil pH value is around the limit. According to these habits of orchids on soil requirements, cultivation substrates that meet the above requirements are generally used to replace traditional cultivation soils.

Fertile soil should be chosen, and fertile soil can make orchids grow better.

Due to the difference in climate between the north and the south, the soil required to grow orchids is also different. In the south, it is necessary to choose soil with good drainage to avoid the environment being too humid to breed bacteria. It can be prepared with pine bark, fairy soil and phytolite, in a ratio of 2:

Around 1:1. In the north, it is necessary to choose a soil with stronger water retention to provide sufficient water for its growth.

It can be prepared with humus, peat and sand, and mixed in a ratio of 6:3:1.

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 can be raised with humus because they contain a lot of humus, which can provide a lot of nutrients for the growth of orchid plants. However, when cultivating orchids, it is not recommended to use only this kind of soil. It can be mixed with a substrate of large grains such as ceramsite, small broken bricks, perlite or volcanic stone.

This helps to increase the aeration and drainage capacity of the soil, making it more suitable for orchid growth.

1. Epiphytic orchid: If the cultivated species is epiphytic orchid, then it cannot be raised with ordinary nutrient soil. This is because epiphytic orchids need to be attached to stones, roots, or bark in order to grow.

In the natural environment, they are also mostly attached to the surface of gravel or to the rhizomes or trunks of other plants. If you only plant them in ordinary nutrient soil, they will not grow well.

2. Ground Orchid: Ground Orchid can be raised with general nutrient soil. However, the quality of general nutrient soil is generally not too good, and there will be shortcomings in air permeability, drainage and fertility, so the effect of breeding will not be too good.

If you want your orchid to grow better, you should plant it in a culture soil that is breathable, drains well, and has sufficient fertility.

If only a single soil is used for cultivation, then it will be better to raise orchids with humus soil than to raise orchids with garden soil. Because humus contains a lot of humus, it can provide more nutrients for the orchid plant, so that it grows better. But in general, it is not recommended to use a single soil to cultivate orchids, and it is best to use a variety of planting materials with different characteristics to prepare the culture soil for raising it.

When raising orchids, it is advisable to use soil that is sufficiently breathable, well-drained and fertile. Because its root system is fleshy, it is more afraid of waterlogging, and it is more beneficial to its root growth to be cultivated in soil with good air permeability and drainage. Soil with sufficient fertility can provide it with more nutrients and help it grow faster and better.

1. Plan 1: Prepare seven parts of humus and three parts of coarse sand, mix them evenly, and you can use them as cultivation soil for orchids.

2. Plan 2: Prepare some coconut bricks, orchid stones and vegetable garden soil, mix them together according to the ratio of 1:1:2, and can also be used as orchid culture soil.

3. Plan 3: Prepare some humus soil, garden soil and saprous bark, mix them together according to the ratio of 3:4:2, and you can use them to raise orchids.

In the practical application of planting orchids. Orchid stone can also be used alone to grow orchids, however, it is not recommended to use it for a long time, because orchid stone itself does not have many nutrients and is suitable for use with organic materials. When planting orchids, there are some special orchids that are picked from the mountains where they grow, and the fertility is better.

The ingredients are pecan shells and pine bark in the picture above, these two materials have the effect of loose breathability and moisturizing and draining, and the three materials are formulated together, that is, the wild orchid is very fond of the soil and trace element content is balanced, the fertilizer effect is long-lasting, the fertilizer is mild and not easy to burn the roots. Rotted cake fertilizer, chicken manure, sheep manure, pig manure, etc. are all good organic fertilizers for orchids. If it is planted indoors or it is not easy to obtain organic fertilizer, the multi-element compound produced by regular manufacturers.

<> foliar fertilization. The use of orchid foliar fertilization has the characteristics of less fertilizer and fast absorption, and orchid foliar fertilization must dilute the fertilizer to a certain concentration and spray fertilizer on the back of the leaves. Orchids alone lack nutrients, and although orchids don't need a lot of fertilizer, they can't be completely without fertilizer.

Fairy soil, fire soil, willow bark, etc. can be mixed with orchid stone as orchid planting materials. Hard planting material for the cultivation of orchids. The roots will be whiter, and the root lengths will look beautiful.

The soil is not so "clean" when it is planted. Personally, I like to add some garden soil when planting orchids, because I think the soil naturally contains some trace elements.

Hard planting material has poor water retention capacity, and can be watered once every 2 days. The moisturizing performance of hard planting material is related to particle size, with large particles, large voids and large evaporation. The particles are small, the voids are small, and the evaporation is small. A mix of large and small particles is used to improve moisturizing properties.

I replenished a class at the time of watering. Orchids not only draw nutrients from the soil but also from their leaves. Not fertilizing within 3 months is talking about the root fertilization method, considering that the root system of the newly planted orchid is not stable and cannot participate in the work effectively, so it cannot be fertilized.

When the orchid is transplanted, when the root system is pruned, it takes a long time for the root system to recover and heal. When fertilizing, when there is no root tip to filter bacteria, the nutrients will be absorbed by the bacteria.

Orchid fertilization can be done using the root fertilization method. Generally, it is to use granules to fertilize slowly, take about 20 granular fertilizers and sprinkle them evenly around the roots of orchids, but not directly on the roots. Add it again in about three months.

Foliar fertilization is also possible. With a watering can, the liquid fertilizer and water are mixed in proportion and sprayed on the leaves. Note: It's best to spray the foliage in the morning before the sun shines.

1) Base fertilizer. The base fertilizer is applied in land preparation, mainly farmhouse fertilizer, compost, and green manure, and it should be fully decomposed when using farmhouse fertilizer.

2) Top dressing. It is the key to the growth of honeysuckle, and the application of well-rotted farmhouse fertilizer or fast-acting nitrogen fertilizer in spring and summer promotes the vigorous growth of the plant. Fertilization method:

Cover the fine soil and press it tightly after application, and water it once; In winter, reapply wax fertilizer, each plant is applied 5 10 kg of rotting manure or compost, 100 grams of ammonium sulfate, 200 grams of superphosphate, after full mixing, apply in the annular ditch around the mound, after the application of the cover soil compacted and watered to moisten, and finally cultivate soil roots around the mound, in order to facilitate wintering.

Fertilization should be based on organic fertilizer as the best, organic fertilizer generally has a balanced content of nitrogen, phosphorus, potassium and trace elements, long-lasting fertilizer effect, mild fertilizer supply, and is not easy to burn roots. Rotted cake fertilizer, chicken manure, sheep manure, pig manure, etc. are all good organic fertilizers for orchids. If it is planted indoors or it is not easy to obtain organic fertilizer, the multi-element compound fertilizer produced by regular manufacturers can also fertilize orchids.

When using chemical fertilizers, it is safest to bury them, dig shallow ditches along the edge of the pot (as far away as possible from the roots of the orchid), spread the fertilizer evenly in the ditch, and then cover the planting material back, this fertilization method will not quickly contact the roots of the orchid, it will slowly contact the roots of the orchid through the dissolution of the moisture of the planting material, the orchid needs a longer adaptation time, and the probability of fertilizer damage is small.

It is not proper, and the pure use of nutrient soil on the market is prone to compaction. Small pieces of bark, ceramsite, phytolite, peanut shells, rotted sawdust, river sand, etc. can be added to make it loose. If it is specially formulated by some Lanjia and declared suitable for separate use of nutrient soil or planting material, it can be considered for separate use.

The nutrients in the nutrient soil are limited, the early stage can meet the nutrient needs of orchids, and the nutrients of orchids will be insufficient when planted for a long time, which may cause the leaves to turn yellow, fall, and die in serious cases, which requires fertilization, and can be applied with special fertilizer for flowers or balanced water-soluble fertilizer when fertilizing, which can effectively supplement the nutrients required for plant growth.
