Plants take root first, and friends who raise orchids know that orchids can't grow strong vitality if their roots are not good. How to raise the roots of orchids depends on the preparation of planting materials. In fact, most other plants are similar, and only suitable cultivation substrates can raise the roots well.
Orchids are fleshy aerial roots, which require high permeability of plant materials, so we must put looseness and permeability in the first place when preparing plant materials. Otherwise, no matter how highly nutritious the plant material is, if it is not transparent enough, the orchid root system will rot because of poor breathing.
In addition to suitable cultivation substrates, rational use of fertilizers is also a necessary condition to promote root growth. Phosphate fertilizer is of great benefit to the root growth of plants, and timely application of phosphate fertilizer in planting management can promote the root system to be more robust. Strong and healthy roots grow in the soil and play the role of loosening the soil. The two complement each other.
In addition, the amount of organic matter contained in the cultivation substrate also determines whether the root system can grow healthily and vigorously. In order to make crop roots explode, what needs to be done is to make the organic matter content of the cultivation substrate higher. Only in this way can more microorganisms be cultivated, and the activity of microorganisms is directly related to the activity of soil.
The above is theoretical knowledge. Let's talk about the actual operation:
When preparing plant materials, you must accumulate thick hair. Large pieces of bark can be used for the coarse, and humus scraped off the mountain can be used for the fine. Then a small amount of phosphate fertilizer is added as base fertilizer, and calcium superphosphate is one of the good base fertilizers.
It is not enough just to prepare plant materials. The most important thing is what is the most taboo for later management of orchid pot soil?
First, excessive insecticidal sterilization will make the microorganisms and flora in the basin soil out of balance, which will lead to the decrease of soil activity and the natural difficulty of root growth.
Second, never turn over the pot once and for all. Some orchid friends don't change the planting materials for several years, and the orchid roots grow very fast, which is easy to cause the old roots in the flowerpot to be congested, leaving no room for the new roots to grow and will slowly rot.
To achieve the above points, generally speaking, the roots of orchids can burst. As long as the orchid roots are strong, the ability to absorb water and nutrients will be stronger, and the orchid plants will grow naturally. Even if there is a minor illness occasionally, only the strong resistance of orchid plants can carry it through.
