The latest propagation method of Rabdosia oleifera

Primrose, also known as litchi grass, is a very common weed in our country. It is an annual biennial herb of Labiatae. Rabdosia sibirica has the effects of relieving diarrhea and relieving cough, anti-inflammation and diuresis. It is widely used to make expansive relieving agent in China and even in the world. Now that there is a certain planting area, how to reproduce planting primrose? The following editor brings you the breeding method of Rabdosia oleifera. Let's have a look!

1. Sowing and reproduction

Sowing and propagation is the most commonly used method of propagation of snow primrose. First of all, we should try to choose the freshest seeds to ensure that the fresher the seeds are, the greater the germination rate will be. Then do a good job of seed soaking, disinfect the seeds, eliminate the germs in the seeds, and promote germination properly to further improve the germination rate of seeds. Prepare the seedling bed and seedling substrate, do a good job of soil preparation and disinfection, and then put the treated seeds into the seedling bed. When sowing, we should pay attention not to hurt the seeds, prevent the seeds from being injured and affect the planting efficiency. After sowing, it is necessary to strengthen management, do a good job in temperature control, water and fertilizer management and diseases and insect pests, so as to improve the emergence rate of seeds. Do a good job in seedling management after emergence, and transplant when the seedlings grow to 8-12 cm and 2-4 true leaves.

2. Cuttage propagation

Cuttage propagation usually uses the tender branches of spring and autumn as cuttings. First of all, it is necessary to prepare a good cutting substrate, which can use river sand, pastoral soil and so on. Disinfect the matrix to prevent carrying germs. Then, during the peak growth period of Saxifraga in spring and autumn, healthy and disease-free branches were selected as cuttings. Cut off the branches, select strong branches, cut down to about 10 cm of disinfection, each section should have 3 leaf nodes. The cut on the ground should be cut flat, and the underground should be cut obliquely to ensure that the incision is smooth, prevent incision infection, and finally be vertically inserted into the matrix. After cutting, it is necessary to control various factors of temperature, light and humidity, in which the temperature is controlled at about 25 degrees and the humidity is about 80%, so as to create a good growth environment for the cuttings of snow grass.

3. Striping propagation

Striping propagation is also a common propagation method of Rabdosia oleifera. First of all, we should select the branches without diseases and insect pests that grow sturdily and have no wound on the surface. Cut a layer of bark about 20-25 cm from the top. The wound should not exceed 1 cm, just cut off the epidermis of the branch. Then prepare the film, put an appropriate amount of moist pastoral soil on the film, cut the wrapping ring, and fasten the ends. After about a month or so, the wrapped part will gradually take root, when it is confirmed to take root, cut off the whole branch, be careful not to hurt the new root and the original plant. After being cut off, there will be a new plant, which can be planted properly.

The above is a brief introduction to the breeding methods of Rabdosia oleifera. The planting direction of the grass determines the different breeding methods. For example, if it is planted on a large scale, it is mainly sowing and cutting. If it is the proper breeding of family potted plants, it will be mainly striped propagation. Therefore, when breeding, we must choose the correct breeding method according to their own planting scale and direction. This article is for reference only. Thank you for your reading.
