The cultivation method of Selaginella officinalis in "reviving the dead"

Selaginella Selaginella is a native or lithophytic resuscitation plant of Selaginaceae, which is mattress-shaped, propagates by spores and has strong vitality. It is often born on sunny hillside rocks or in dry rock crevices. Here is an introduction to the breeding method of Selaginella officinalis.

I. the growth habits of Selaginella officinalis

Selaginella officinalis has very strong vitality, and the root can separate from the soil by itself, curl up like a fist, move with the wind, and be proud when it comes to water. The root goes back to the soil to look for moisture, and after a long period of drought, as long as the root system is soaked in water, it can stretch again, so it is named "reviving grass from the dead".

2. Culture methods of Selaginella officinalis

1. Soil selection and planting

The soil adaptability of Nine death returning Grass is very strong, and there is little requirement for the soil, but it grows faster and the plant is more robust in the sandy soil with strong permeability and good drainage and irrigation.

Selaginella officinalis can be planted in the south all the year round, and the north should choose summer, late autumn and other high temperature weather, and choose planting methods according to their own planting techniques, generally speaking, they are mainly divided into stems and propagated. The seed stem is cut into small segments of about 5 cm and sowed on the soil, and the times of watering should not be less than 3 times a day before germination to ensure that the soil is moist and can take root and survive.

two。 Water and fertilizer management

Dead grass has a relatively large demand for water and likes to grow in a humid environment. If there is not enough water, the plant will be weak, collapse and soft, which will seriously reduce the ornamental value. Therefore, when we breed, we should ensure that the soil water content is sufficient, timely watering, meet the water demand, and reasonably adjust the watering frequency according to the changes of the weather.

Water should be watered at least twice a day in summer and about once every 4 days in winter, and topdressing should be done to ensure adequate nutrition. During its growth period, it is usually applied once a month, pay attention to fertilizer concentration, not too high, to avoid burning plants.

3. Shaping and pruning

The reviving grass is mainly ornamental, so shaping and pruning is something we should pay attention to when we breed. When topdressing, we should avoid using too much nitrogen fertilizer, prevent the plant from growing too much, improve the permeability of the garden, and enhance the growth ability of the grass.

Selaginella officinalis needs to be pruned regularly, the branches that are too long and too dense can be cut off, and they can also be trimmed into various shapes according to the needs of the market, so as to make them more beautiful, enhance commodity value and expand their own breeding benefits.

4. Pest control

Although the dead reviving grass has strong growth ability, there are also common diseases and insect pests, such as leaf spot and brown soft scale, which we also need to focus on prevention and control. We should manage the temperature and humidity around the planting site well. Although we like water, the humidity should not be too high. It is necessary to keep the temperature and humidity within a stable range, regularly inspect the garden, prepare control agents for common diseases and insect pests, strengthen garden management, and do all the preventive work. Reduce the incidence of disease.

The above is a brief introduction to the breeding methods of Selaginella officinalis. In the process of planting Selaginella officinalis, pest control is more important, which will not only damage the appearance of Selaginella officinalis, but also threaten the growth of Selaginella officinalis.
