Plant materials for orchid cultivation

If you want to grow orchids well, planting material is the foundation. How to choose the plant material suitable for orchid growth? According to the experience of raising orchids for many years, the author talks about his personal views.

First, plant materials are matched with orchid pots. At present, most orchids choose tile pots, purple sand pots, pottery pots and so on. Due to the different air permeability of these orchid pots, the plant materials selected for growing orchids are also different. Tile pot, because of its excellent permeability and hydrophobic performance, good moisture retention, the plant material used can be smaller; choose purple sand pot or pottery pot to cultivate orchids, because of its poor air permeability, summer and autumn are affected by the weather, the flowerpot absorbs heat quickly and dissipates heat slowly, so the plant material used can be thicker. In short, the plant material should be matched with the size and depth of the orchid basin, depending on the type of orchid basin.

Second, the selection of plant materials according to the author's experience, first, the reasonable selection of humus soil in the original place. The black humus soil with dead branches and leaves in the mountain stone crevice or the humus soil on the surface of mountain pine forest is the most suitable, which can not only increase the nutrients of orchids, but also benefit the growth of orchid roots. Second, add a little brick. It is best to select green bricks and soak them in water for 3 to 5 days before use, so as to remove the alkaline substances and anger in the bricks, so as to enhance the air permeability and water absorption of the bricks themselves. With its cultivation of orchids, the flower roots will not be black and rotten, and Ye Yilan will not walk. Third, the proper use of cinder. As the cinder is burned at high temperature and contains a lot of alkaline matter and fire gas after cooling, the cinder must be soaked for a few days before use to remove the alkaline matter in the brick particles to be dried. The annealed cinder is absolutely harmless to the orchid. Fourth, the skillful use of fired turf soil. The turf soil roasted at low temperature contains a lot of phosphorus and potassium fertility, as well as a small amount of manganese, iron, calcium and other trace elements, such as used to grow Yilan, the orchid plant is strong, the production is high and relatively stable.

Third, the proportion of plant materials should be suitable if the tile basin is selected as the orchid basin and the humus soil in the original place is selected as the plant material, the humus soil in the original place should account for 70% of the mixed plant material, and a little charcoal or brick should be used as the basin bottom. If you choose purple sand basin or pottery basin as orchid basin and brick grain or cinder as planting material, the proportion is 40% to 60%, with 30% to 40% pond mud and a little foam fragments as the bottom of the basin. Select fired turf soil as the main planting material, the proportion can be between 60% and 70%, mixed with charcoal and brick.
