Adaptation of orchid pots and plant materials

Common orchid planting pots include mud pots, purple sand pots, purple sand glazed flower pots, south mud pots, coarse pottery glazed pots, fine pottery pots, plastic pots, etc. Due to the characteristics of materials, the pots formed have different porosity (micropores), and the size of porosity determines the hygroscopicity and hygroscopicity of orchid pots. Pore and pore differ greatly in geometric size, pore has moisture absorption and discharge function, and pore is used for ventilation. Moisture absorption and discharge should be a criterion for evaluating the performance of pots. When water is poured into the pot, excess water is drained from the bottom hole in the first stage, when the plant material reaches saturation water absorption state. If orchids are regarded as plants that do not like water, in the second stage, the pot with good moisture absorption and drainage can be used through the siphon of pores to conduct the moisture contained in the plant material to the outer surface of the pot and emit it into the air. This slow process continues until the ambient humidity is close to the humidity in the pot. The moisture of the plant material in the basin is not only led out by the basin wall, but also evaporated by the basin surface and other holes on the basin.

Pots with poor moisture absorption and drainage and without absorption and drainage, the water in the plant material in the pot mainly depends on the pot surface and pores to disperse (without considering the absorption of plant roots). The process from watering to the end of the plant's moisture dissipation in the pot can be regarded as the watering cycle.

The saturated water absorption of various plant materials is different, and the ability to absorb water depends on the structure of the plant material. The water absorption capacity of microporous particles with large specific surface area is obviously greater than that of weathered rock particles with dense structure, and the whole basin of mountain mud is easier to absorb water than the whole basin of sintered pond cornerstone. When the pot with different absorption and discharge and different water retention rate of plant material adaptation, its irrigation cycle should be different, growers must be based on the selected pot and plant material and environmental temperature and humidity to determine the irrigation cycle, must not generalize and listen to their immature experience.

As far as the orchid pots and planting materials selected by the current orchid growers are concerned, it can be said that radish and cabbage have love. Some people pay great attention to the hygroscopicity and hygroscopicity of the orchid basin, and choose the loose organic matter plant material planted in the mud basin and fermented fully. Orchid root in the plant material is not empty suspension, moderate fertilization, watering, excess water from the pot wall of the pores absorbed to the pot wall evaporation, rarely occur water damage root phenomenon. Although the traditional point, the growth rate is not very fast, but the disease is less, the orchid grows fruit, not "vegetables", the fragrance reaches the fragrance and purity, and the orchid grows very much like orchid. Some people use plastic pots and sintered particles to plant orchids, especially the name of the particles is really nice, called "planting gold stone". This concept was enough to entice people to compare it to gold. It didn't matter if it was organic or inorganic. In any case, people said that it contained trace elements. Today is to praise trace elements, and moreover, raised for several years also flowering, but also incense, but also love hair seedlings. Langen seemed to be wronged, but some orchids grew worse on the mountain than this. After a high-tech fertilizer urge, orchid seedlings long brush, like using fertilizer to produce bean sprouts, very high-yield, high efficiency, orchid or orchid. 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 grow, just look at the exquisite craftsmanship of the basin and basin table is enough to be pleasing to the eye, who cares if the basin wall is not permeable to moisture, it is bad to be permeable to moisture, dirtying the basin is a major event, passing it on to future generations, and placing it on the ancient shelf will add value. Celebrities wear good clothes, good horses with good saddles, delicate orchids planted in expensive pots, make rich and beautiful. There are also random pots, pots are diverse, plant materials are various, irrigation cycle is the same, but still divided into spring, summer, autumn and winter, a large number of raw plant materials mixed is common, orchid disease can not find the root cause. It can be imagined that there are so many variables, summing up experience, finding out the law is very difficult, Lan Yang thought it was due to sincerity, and if he couldn't raise it well, there was that sentence to help get rid of it,"watering for three years".
