1. Choose loose, breathable plant material. Therefore, in the selection of planting materials, granular material should be used instead of powdered plant material to facilitate orchid root respiration.
2. Select plant material that is moisturized and does not contain water. Orchids need moisture to moisturize, but their roots are mostly fleshy roots that are not resistant to stagnant water. A good plant should be able to water and flow, never water, but also to maintain a longer period of moisture.
3. Choose plant materials that are both clean and have high fertility. The growth of orchids, like other plants, is inseparable from all kinds of fertilizers and the intrusion of diseases. The cleanliness and fat content of the plant material are essential for the normal growth of orchids.
According to the growth characteristics of orchids, especially people's long-term experience of raising orchids, the planting materials of the cultivated orchids that can be selected by the breeding orchid lovers are various. The general planting orchid planting materials can be roughly divided into three categories:
1. Earthy materials: There are mainly mountain mud, pond mud, bamboo root soil, peat soil and various humus soils. These matrices are the main materials of the traditional method. Its advantages are moisturizing, containing fertilizers, convenient materials, and low cost. The disadvantages are that it tends to form stagnant water, and often contains germs and pests. However, Sichuan Xiantu and some artificially produced granular soil currently sold on the market have not been traditional soil materials. According to my many years of experience in raising orchids, it is better to use these two planting materials. One is Sichuan cents plus giltite or volcanic stone and granule orchid mud, and the ratio between them is one-third each of immortal earth, phytolith, and granular orchid mud. The other is the orchid mud digging directly from the mountain, which is known as the lime-soil in the Siming Mountain area. After being sterilized and sterilized by sunlight, the selected granular mud is best planted. Orchids grown entirely from granule orchids are particularly pure during the flowering period. They are particularly fragrant and grow well if they are not fertilized for a year.
2. Organic matter: There are bark, dead wood, cocope, sawdust, bagasse, peanut shell, snake wood, brown silk and moss plant. The main advantage of this type of planting material is that it provides organic fertilizer for orchids after moisturizing, ventilating and rot. It is conducive to the growth of orchids. The disadvantage is that they are prone to diseases and insect pests. Especially in the process of decomposition and rot, heat and harmful substances are generated. Roots, and in the orchid leaves will produce many lesions, affecting the product phase.
3, hard material species: There are mainly base stone, planting stone, volcanic stone, stone, perlite, broken bricks and ceramic particles. The selection of such planting materials is the result of people's constant exploration and optimization in the practice of raising orchids. Its advantages lie in that it should not be broken in granular form, clean and free of insects, and has good air permeability, and it is not easy to be compacted or water. The disadvantage is that it is easy to dry. Fertility, if the grain size is not properly selected, it is not conducive to the growth of orchid root, and it is not suitable for the family to support under natural conditions.
The choice of planting and planting materials
With the continuous improvement of people's material level, the spiritual needs have also been continuously enhanced. The cultivation of flowers and grass has become a method for many people to cultivate themselves and cultivate their minds. However, breeding orchids is their preferred species because of the elegant temperament and character of orchids. Appreciation for ancient literati. It is not a difficult matter to raise a good orchid. As long as you understand the characteristics of orchid growth, depending on how you take care of it, choose a good planting material, put it in a suitable place, and the orchid can grow healthily, so choose a suitable The planting of the plant material itself is very important, because the orchids absorb nutrients through the Langen to absorb the channels. In the natural environment, orchids are mostly grown in areas with abundant humus, loose soil, and dryness, but where the air humidity is high, the blue leaves absorb moisture from the air to make up for lack of water that is lacking in water absorption. Therefore, pay attention to the following points when choosing planting materials:
