2. Propagation methods of Rosemary

1. Seed propagation

Seedlings are generally raised in the greenhouse in early spring. Raising seedlings by taxi method and raising seedlings by acupoint plate can be used. In order to raise seedlings by native method, the seedbed should be arranged first. The seedbed can be a flat bed or a small high bed, and the bed soil should be broken into pieces, fertilized with fermented base fertilizer and watered with sufficient bottom water. It can be broadcast or broadcast. However, the seeds are sparsely sown as far as possible, or mixed well with fine dry soil, sowed on the seedling bed and poured with small water to make the seeds fully contact with the soil. The seeds have good light, and the seeds are sown directly on the medium without mulching, and a small arch shed is built on the border surface, which not only ensures the ground temperature, but also makes the soil surface difficult to harden. Seeds are developed by the water at the bottom of the seedling bed, but keep the soil surface moist all the time. Wait for the top of the bud to be unearthed and then watered, based on the principle of diligent irrigation with small water. The optimum temperature for seed germination is 15-20 degrees Celsius, about 2-3 weeks. When the seedling grows to about 10 cm, about 70 days, it can be planted. For burrowing seedlings, mix peat and vermiculite at 3:1 and sow seeds. Cover with a thin layer of vermiculite and pour water once. Build a small arch shed, and then manage the same soil method to raise seedlings. The difference is that after the emergence of rosemary, it is necessary to move the acupoint plate from time to time to prevent the root from breaking into the ground along the hole below the burrow plate and injuring the root when planting. If you put the acupoint plate on the shelf, it will not be necessary. The bud rate of rosemary is very low, generally only 10%-20%. Moreover, in the first year, the growth of rosemary is very slow, even in autumn, the plant size is not much larger than that when it was first planted, and a large yield will be formed after 2-3 years. Slow. Therefore, asexual reproduction is generally used in production. But from the seed cultivation, the smell is more fragrant, so the use of breeding methods, depending on the needs.

2. Cuttage propagation

Mostly from winter to early spring, select fresh and healthy stems that have not yet been completely lignified as cuttings, cut off about 10 centimeters from the top, remove about 1 inch 3 leaves under the branches, and insert them directly into the medium. it will take root after about 3 to 4 weeks, and it can be planted to the open field after 7 weeks, and the lowest night temperature of cutting is 13 degrees Celsius.

3. Striping propagation

Making use of the characteristic that rosemary stems can produce adventitious roots, the branches close to the ground are pressed to cover the soil, leaving the top in the air, waiting for new roots to grow, cut from the mother to form new individuals, and planted in the open field.

The role of rosemary can be said to be very wide. Raising a pot of rosemary at home can not only beautify the environment and purify the air, but also help enrich dishes.

At present, the most ideal method is to use biological control.

4. Rosemary propagation

The suitable propagation methods of rosemary include sowing, cuttage, striping and so on. Rosemary seeds germinate slowly and have a low germination rate, so they are usually used only when introducing new varieties. During the rooting period, the suitable temperature in the greenhouse is 22 ℃, and the cuttings should be sprayed frequently, but too much moisture will cause the top of the cuttings to rot and the roots produced are not strong enough. In the first 10 to 14 days, cuttings begin to take root, and special attention should be paid to preventing cuttings from wilting.
