Propagation methods of Rosemary

Rosemary is a shrub plant of Labiatae, its origin is in Europe and Africa, but it has been introduced into China thousands of years ago and has a certain ornamental value. However, rosemary is mainly used in daily chemical, pharmaceutical and food industries, because rosemary is the main raw material for the production of antioxidants and essential oils of rosemary. Now the planting area of rosemary is relatively wide, so how to reproduce rosemary? The following editor will introduce the breeding method of rosemary to you.

1. Seed propagation

Seed propagation is the most common method of propagation of rosemary, which usually begins to raise seedlings in early spring every year, and the method of raising seedlings depends on their own habits. If it is a native method of raising seedlings, we should do a good job in the management of the seedbed, just the seedbed, plough the nursery bed deeply, and then apply sufficient fertilizer to better water. When sowing, pay attention to the density, should not be too dense, can be properly sparse. Before sowing, mix the seeds with the soil, and then sow to expand the contact area between the seeds and the soil. And after sowing, cover with plastic film or build a small arch shed for heat preservation to prevent soil consolidation. What we need to pay attention to is to move the point plate regularly after emergence to prevent the root from extending into the ground and cause damage to the root during planting.

2. Cuttage propagation

Cutting propagation is generally used when propagating at the end of winter, and rosemary plants with disease-free and harmless, stout stems and not completely Lignified stems are usually selected as cuttings. Cut off the stem about 12 centimeters from the top, and properly remove the leaves below the branches, leaving 2 to 3 leaves. After cutting, the branches are inserted directly into the medium to keep the soil in a moist state. If it is properly managed, it will take root in about a month. Then you can transplant and plant in a month, pay attention to the temperature when cutting, especially at night, the temperature should not be lower than 14 degrees.

3. Striping propagation

Striping propagation is another way of propagation according to the characteristics of rosemary, because rosemary often produces some adventitious roots, and adventitious roots are the premise of strip propagation. The method of striping propagation is very simple, pressing the branches closest to the ground into the soil. Then the top of the branch will be exposed, and the pressed branch will gradually take root, and then the branch will be cut off from the mother plant, so that the branch will form a new plant, and then transplant.

4. Points for attention

The natural germination rate of rosemary is very low, usually only about 1 to 5 or less. And the growth rate of rosemary is very slow, the growth period is very strong, it is planted in spring, and in autumn you will find that the plant is not much bigger than when it was planted. The peak growth period should wait for at least 2 years, so rosemary is usually propagated asexually, but the plant produced by seed has a stronger flavor and better quality. So which method of reproduction to use is mainly based on your own planting direction and needs.

The above is a brief introduction to the breeding methods of rosemary, which are basically the three kinds of rosemary. However, each method of reproduction has different advantages and disadvantages, as just said that the seeds reproduce for a long time, but the quality is good. Therefore, before planting, we should not only consider the planting technology, but also be prepared for reproduction. That's all for today's introduction. This article is for reference only.
