Exclusive spring as a kind of orchid and other orchids, is not suitable for propagation by sowing
This is because its seeds are very small, thick testa and waxy, so it is difficult to absorb water. In addition, its intraspecific structure is not complete, the development of embryo is not complete, the slice embryo is not mature, and it lacks the support of nutrition. This causes it to sprout in the ordinary way.
There is also a lack of orchid bacteria. Orchid fungus is a kind of fungus associated with orchid. It can invade its mycelium into the root of orchid and form a symbiotic relationship with orchid. Orchid can get nourishment and water from it. It can also absorb carbohydrates and other substances from orchid. In addition, it can also provide some substances that are missing in the seed when it germinates, which can be used when it germinates.
In order to plant exclusive spring by seeding, the problem of insufficient seed germination must be solved first. Therefore, we can choose some planting soil containing orchid bacteria for planting.
First, choose a flowerpot of moderate size, and put the prepared planting soil into it. Planting soil should have good air permeability, which is conducive to seed germination. The fertility of the soil to be planted should be moderate, not too much
Put the seeds on the surface of the planting soil, and then cover them with the planting soil to keep them out of the soil. Because its seed volume is very small, it can use tools when sowing to avoid damaging seeds. The soil on the seed should not be too thick, about 1cm
Finally, we need to wet the planting soil and give it a good germination condition.
In the laboratory sowing can use the medium to provide the seed germination needed nutrition.
First, the seeds were soaked in 10% sodium hypochlorite solution for 5-10 minutes, which weakened the seed coat and increased the permeability of nutrients. Then wash with pure water and dry.
Then spread it on the container containing the medium, and culture in a dark room at 25 ℃.
When it germinates, it can be moved to light to form a seed ball for sowing.
