It has many varieties, mainly divided into fine leaf and broad leaf. Different kinds of soil are used in planting, but most of them are rotten leaf soil. Among them, the planting of fine leaves mainly uses saprophytic soil, while the planting of broad leaves mainly uses solid soil. However, it depends on the cultivation environment to which extent.
1. When planting, the simplest soil ratio is to mix laterite and saprophytic soil. The ratio is about 3:7, so that the nutrients are sufficient and conducive to plant growth.
2. If it is not convenient to obtain red soil during planting, it can also be mixed with garden soil and appropriate amount of rotten leaf soil. Specifically, the garden soil, the field soil and the rotten leaf soil are allocated according to the ratio of 3:2:5. However, garden soil and field soil are usually cultivated mature soil, so you can increase the amount of
3. When orchid is cultivated and maintained, the soil should have certain air permeability, so it can also be mixed with appropriate amount of sand and soil, which is better to use coarse sand, with better air permeability and drainage. It is made up of three parts of coarse sand and seven parts of rotten leaf soil.
When planting orchids, no matter how to prepare the soil, we should pay attention to the three points of permeability, water retention and humus content as the benchmark. If only humus is included, but the permeability is not good, the root system is easy to rot in the later stage and cannot survive. If the air permeability is good, but there is no humus, nutrients are not enough, the growth will be affected.
