Also talking about the cultivation substrate

There are many kinds of matrix materials used in orchids in China, the traditional materials are humus, and pond mud is commonly used in Guangdong. The soil containing a lot of humus, loose, well drained, neutral or slightly acidic (PN6.5-7. 0) is the most ideal.

The traditional orchid in Guangdong uses tang ni, that is, the topsoil in the fish pond, which is thin and dried in winter (about 1 inch thick), and then broken for the orchid, the bottom is thick and fine, the organic matter is rich, there are many voids in salt, and the water is permeable. But must be of good quality, poor quality of the pond cement, easy to touch, a lot of disadvantages, not suitable for use. Experienced orchids grow traditional broad-leaf orchids with good texture pond mud, and the effect is very good. Mud (commonly known as Lannai) is often used in Jiangfu area, such as Yanwo Ridge in Yuyao, Zhejiang Province, Stone Mountain in Fuyang, mud around Baoshu Pagoda in Hangzhou, Tongguanshan Mountain in Yixing, Jiangsu Province, Junshan Mud in Nantong, and Yushanzi Mud in Changshu. The mud is loose and clumpy in the hands, and the hands are spread out and slightly shaken, that is, loosely opened. The collected blue mud first leveled the ground of the thin stall, let the sun shine, and turned it layer by layer for several days to achieve daylight disinfection and sterilization. Then use fine sieving to remove Agen weeds and use them.

For beginners to grow orchids, vegetable garden soil and one of two pairs of sand can be used after disinfection. You can also use cow dung soil, that is, the fermented dry cow dung is crushed and ground, mixed with sandy soil or field, and prepared at the proportion of 1:3. It is best to choose cow dung that eats hay in winter, because after ruminating, the hay still has fine broken fiber, but it is still elastic and has certain nutrients. This kind of cow dung soil is soft and fat, which is very suitable for the excellent temperament of Tylan.

In addition to the above traditional materials, at present in Hong Kong, Taiwan and some parts of Guangdong. The matrix materials used in orchids are longan bark, capsule root, water moss, upper forest stone, white stone, broken brick, broken tile and ceramsite to be prepared. Among them, capsule root (commonly known as snake wood) is the most commonly used matrix material for orchid culture in Japan and Taiwan, which is safe and effective. When the author was on an inspection tour in Hong Kong, an orchid enthusiast invested 200000 yuan to raise a batch of rare orchids, of which several pots used glass fiber as the matrix, grew very well, and the root system was very strong. Ye Maohua is also very beautiful.
