Orchid with perlite. Is that good?

It is better to raise orchids or perlite.

Flower friends who like to raise orchids should know that if you want to raise orchids well, you must first raise roots. Because only when the root system is developed, the orchid can grow strong and vigorous. So how do you give roots to orchids? If we want to raise good roots for it, then we must first learn to mix soil with orchids.

When it comes to the soil for orchids, many flower friends find it difficult, because there are a lot of planting materials for planting orchids. In fact, as long as everyone adheres to a principle, the soil will become very simple. The principle is: both hard and soft.

Because there are two kinds of soil for planting orchids, one is soft material and the other is hard material. In order to make the orchid root system grow well, we must achieve "soft and hard" when mixing soil.

So, what is "hard and soft"? For example, fermented pine bark and peanut shells.

This is the soft material; Like vermiculite.

Volcanic rocks, small stones.

This is hard planting. Therefore, when we match the soil for the orchid, we must first look at the roots of the orchid, and then match it with the appropriate soil according to the condition of the root system.

If your orchid root system is not particularly good and not very developed, you can put more soft materials like the roots can touch when mixing soil, that is, put more soft planting materials. We can put 70% pine bark and add 30% perlite to it, and that's it.

If your orchid root system is particularly good, and there are white crystal roots inside, then when we match it with soil, soft planting material and hard planting material can account for half each; It is also possible to mix all kinds of soft planting materials and various hard planting materials together, and each one is half.

If you are a novice in raising orchids and have not been exposed to orchids before, the first time you give it soil, it is best to give it 70% of hard planting material and 30% of soft planting material, so as to ensure that the orchid soil is very permeable and breathable, so that it is not easy to rot roots.

In the process of orchid maintenance, water-soluble fertilizer can also be appropriately applied to supplement nutrients.

Perlite is relatively better for orchids with soil, after all, the particles are small, leaving more room for orchids to take root. Configure the soil, you can use humus, which can be added with granular soil, sawdust, coarse sand, and Bika granular fertilizer, so that the preparation can ensure that it is soft, breathable, and has a certain amount of nutrition.

It is better to add perlite to orchid soil, the weight is relatively light, and there is good hygroscopicity, which can ensure the loose, breathable and moist characteristics of the soil around the roots of orchids. It is more conducive to the growth of orchids.

Perlite, vermiculite and orchid stone differ in structure, aeration permeability, and nutrient content.

1. Structural differences.

Perlite is a rock formed by volcanic eruptions, and its shape has a distinct fractured structure. Vermiculite acts like sand, and the biggest difference between the two is that perlite is much lighter and more suitable for express delivery than orchid stone. Orchid stone is a porous and light stone formed by a special temperature after a volcanic eruption, releasing a large amount of gas and heat.

2. Difference in ventilation and water permeability.

Perlite almost does not absorb water, not the usual legend of strong water retention, its biggest feature is that the aeration is relatively good, the water content is average, generally in the process of breeding plants, if the water is absorbed, it will be due to expansion, the water inside is easy to flow, so it has a strong drainage ability.

When vermiculite is watered, the lower layer will easily have problems due to drainage, and its drainage ability is not as good as perlite. The disadvantage is that the physical state will change after a long time, and the ventilation and drainage will be reduced. Mixed into the soil, the soil air permeability and drainage are improved, and the water and fertilizer retention capacity is much stronger than that of orchid stone.

The aeration and water permeability of orchid stone particles is too good, which will greatly shorten the storage time of orchid water in the pot. As a result, the frequency of watering and the use of liquid manure increases, which greatly increases the workload in daily management.

3. Differences in nutrients.

Vermiculite is a natural, non-toxic mineral, which swells under high temperatures and is a rare silicate mineral, which has a great effect on the nutrition of the soil, and is the best sterile and non-toxic substrate for some soilless cultures. Perlite does not have any pathogens and grasses, and is the most widely used cultivation medium for us, which can promote the growth and development of plants when used for cultivating plants.

Orchid stone itself does not have much nutrients, in the cultivation of orchids, orchids will lack the required organic nutrients, so it is necessary to regularly and quantitatively increase the amount of organic matter fertilizer. And when used for cuttings, they are no worse than sand, and the greater advantage is sterility.

The differences are: different definitions, different uses, and different characteristics.

1. Different definitions: perlite is a kind of acidic lava formed by volcanic eruptions, which is formed by rapid cooling; Vermiculite is a natural, inorganic, non-toxic mineral that swells when exposed to high temperatures. Orchid stone is a porous, lightweight, and rapidly absorbs nutrients and retains water formed by a special temperature after a volcanic eruption, which releases a large amount of gas and heat.

2. Different uses: perlite can be used for rubber and plastic products, pigments, paints, inks, synthetic glass, and heat-insulating bakelites; Vermiculite is widely used in thermal insulation materials, fireproof materials, seedlings, flowers, trees, friction materials, sealing materials, electrical insulation materials, coatings; When the orchid stone is wet, it has a golden color and is used in conjunction with elegant orchid plants.

3. Different characteristics: perlite has the characteristics of light apparent density, low thermal conductivity, good chemical stability, wide range of operating temperatures, and small moisture absorption capacity; Vermiculite also has good water absorption, sound insulation, heat insulation, fire resistance, and frost resistance; Orchid stone has the characteristics of light body, drainage, moisturizing and air permeability.

Because the purpose of perlite ore beneficiation is to process the selected raw ore into products that meet industrial requirements in terms of particle size, moisture and other indicators, that is, perlite ore, it is determined that the beneficiation process of perlite is very simple, usually crushing-grading-drying.

Perlite brittle grains are commonly used as a matrix, vermiculite is breathable and water-stored, and orchid stone is not understood.

It is better to raise orchids or perlite than river sand and stone; Perlite is mainly used to increase the permeability of potting soil, improve the structure of the soil, and reduce the possibility of compaction. Because it is cheap, it is widely used by art dealers, but because of its light weight, it will float up when it is poured with heavy water. With peat, it is better than river sand.

Perlite is a volcanic eruption, acidic lava that has cooled sharply into a vitreous rock,[1] so named for its pearly fissure structure. Soilless substrate is a promising application field in agriculture, plant and horticulture. Some large-grained perlite is gradually being used in vegetable seedlings as an essential component of seedling soil to increase the air permeability and water absorption of nutrient substrates.
