Adaptation logic of orchid pot and plant material

Carry forward the national orchid culture and spread the knowledge of orchids

Common orchid pots include mud basin, purple sand basin, purple sand glaze pot, south basin, coarse pottery glaze basin, fine pottery basin, plastic basin and so on. Because of the characteristics of materials, the formed pots have different porosity (micropores). The size of porosity determines the moisture absorption and dehumidification of the orchid basin. There is a great difference between the pore and the hole in geometric size, the pore has the function of moisture absorption and dehumidification, and the function of the hole is to permeate. Moisture absorption and dehumidification should be a standard to evaluate the performance of pots. When the water is poured into the basin, in the first stage, the excess water is discharged from the bottom hole, and the plant material reaches the state of saturated water absorption. If the orchid is regarded as a plant that does not like water, in the second stage, the basin with good moisture absorption and drainage can be used through the siphon of micropores to transport the water contained in the plant to the outer surface of the basin and distribute it to the air. this slow process continues until the environmental humidity is similar to that in the basin. The moisture emission of the plant material in the basin is not only derived from the basin wall, but also evaporated by the basin surface and other holes in the basin.

For pots with poor hygroscopicity and non-absorbability, the water in the plant material in the basin is mainly distributed by the basin surface and holes (without considering the absorption of plant roots). The process from watering to the exhaustion of plant moisture in the basin can be regarded as a watering cycle.

The saturated water absorption of all kinds of plants is different, and the ability of water absorption depends on the structure of the plant. The water absorption capacity of porous particles with large specific surface area is obviously larger than that of weathered rock particles with dense structure, and the whole basin of mountain mud absorbs water more easily than the foundation stone of the whole basin. When the pots with different suction and drainage characteristics and plants with different water retention rates are adapted, the irrigation cycle should be different, and the growers must determine the watering cycle according to the selected pots and plants, as well as the environmental temperature and humidity. Never generalize and believe that it is not suitable for your immature experience.

According to the orchid pots and plant materials selected by the current orchid growers, it can be said that radish and cabbage has some love. Some people pay great attention to the absorption and dehumidification of orchid basin, choose mud basin and fully fermented loose organic matter plant orchid. Langen is not suspended in the plant material, fertilizing moderately, and after watering, the excess water is absorbed and discharged from the micropores on the basin wall to evaporate outside the basin wall, and the phenomenon of water damage to the root system rarely occurs. Although traditionally, the growth rate is not very fast, but the disease is less, the orchid is strong, not "vegetable", the flower fragrance reaches the aroma and purity of the fragrance, and the orchid looks very much like the orchid. Some people use plastic pots and sintered particles to plant orchids, especially the name of the particles is so beautiful, called "gold planting stone". This concept is tempting enough to use orchid as a metaphor for gold, a good dream come true, regardless of whether it is organic or inorganic, anyway, people say that it contains trace elements. Today is respected trace elements, and, raised for several years also bloom, but also fragrant, but also love to sprout. Langen seems to have been aggrieved, but the growth conditions of some orchids on the mountain are not as good as this. After the promotion of high-tech fertilizer, the growth of orchid seedlings brushed, just like using chemical fertilizer raw bean sprouts, very high yield, high efficiency, orchid or orchid.

While some people plant orchids to highlight elegance and luxury, and try to reflect the profound cultural heritage of orchids from pots. Not to mention how the orchids look, just looking at the exquisite craftsmanship of the pots and pots is enough to be pleasing to the eyes, who cares whether the basin wall is permeable or not, it is bad, soiled, unsightly is a major event, passed on to future generations, placed on the ancient shelf is to add value. Celebrities wear good clothes, a good horse with a good saddle, Guerlain expensive pot planting, all the rich show. There are also candidate pots are random, the pots are diverse, the plant materials are various, and the irrigation cycle is the same, but it is still divided into spring, summer, autumn and winter, and it is common for a large number of raw plant materials to be mixed in, and the root cause can not be found even if Lan gets sick.
