A blue stone that can breathe

There is a kind of stone that is white when it is dry and becomes brilliant golden yellow after soaking through. There is a kind of stone with tiny pores, which can not only quickly remove excess water for the orchid plant, but also moisturize the orchid plant for a long time. This kind of stone is called "gold planting stone" and is affectionately called "breathing stone" by Lanyou.

The total collection of horticultural materials of buffalo is the only distribution unit of Japanese volcanic stone "planting gold stone" in China. According to Chen Rongyu, general manager of the company, the plant gold stone, which originated in Kagoshima, Japan, is a porous, light-weight stone that releases a lot of gas and heat after a volcanic eruption and is formed by a special temperature. It is a stone that can quickly absorb nutrients and retain moisture. It is processed by high-tech technology after 250 ℃ high-temperature sterilization.

After years of application, gold planting stone is favored by many orchid friends because of its excellent characteristics. At present, it has been widely used in all kinds of precious orchid planting, and its advantages are mainly reflected in the following aspects:

First of all, the air permeability is good, which helps the orchid breathe.

The gold plant stone has an obvious characteristic in the physical structure, its internal gap is in the shape of a long flat gap, rather than the general blue stone internal round pores, and its density is smaller than the blue stone, so the air permeability is better. Increasing the dosage in the upper half of the soil layer can help plants dissipate heat in summer with its special structure, and because the hardness is not high, it will not hinder the growth of plants.

Secondly, it can drain and absorb water, so as not to let the orchid get too wet or too dry.

Some Lanyou once did an experiment to fully water the gold plant stone in the orchid basin. When there was no excess water flowing out of the basin bottom, the plant stone was poured out and was directly squeezed by hand, unable to squeeze out water, which indicated that the drainage was good. And put the soaked gold stone on the ground to spread flat, put in a cool and ventilated place, the temperature is about 25 ℃, a week later, the appearance of the plant stone is still slightly golden, 15 days later, the plant stone core is still about 2 mm wet, which shows that the plant stone has good water retention. This characteristic is a good thing for beginners of orchids, which can reduce the damage caused by overwatering or underwatering to orchid plants.

Third, do not drop the residue, it is not easy to residual medicine and fertilizer liquid.

After washing the plant stone, soak in water for 12 hours and then rinse, the washed water is still close to clear, indicating that the agglomeration meets the requirements-no slag. The structure of phytolith is solid, and the fertilizer solution can not be permeated and retained, which will not lead to too high concentration of matrix solution and affect the growth of orchids.

Fourth, the utilization rate is high and the appearance is beautiful.

The gold plant stone can be reused. After pouring out after changing the basin, after cleaning, soaking and disinfecting the solution, it can still be used continuously. The general service life is 2-5 years. After planting gold stone wet water, the color is golden, with elegant orchid plants, complement each other, can improve the grade of orchids.

At present, there are some fake gold plants on the market, which can be distinguished by watching hands and touching them. The real gold plant stone is characterized by light texture, powdered with hands, fine pores on the surface, milky white and yellowish normally, and golden yellow when entering the water.
