2. Rosemary propagation method
1. Seed propagation
Seedlings are usually raised in the greenhouse in early spring. Both Shifa seedlings and plug seedlings can be used. To raise seedlings using native methods, the seedbed needs to be prepared first. The seedbed can be a flat border or a small raised border. The soil in the bed should be broken up and leveled. Apply enough fermented base fertilizer and pour enough water. Can be broadcast or drilled.
However, the seeds should be sown as sparsely as possible, or mixed with fine dry soil, sown on the seedbed, and poured with light water to fully contact the seeds with the soil. The seeds have good light properties. Sow the seeds directly on the medium without covering them. Set up a small shed on the border to ensure the ground temperature and prevent the soil surface from hardening.
Seeds rely on water at the bottom of the seedbed to develop, but the soil surface must always be kept moist. When the tops of the buds are unearthed, water them again, with the principle of frequent irrigation with small amounts of water. The suitable temperature for seed germination is 15 to 20 degrees Celsius, and it takes about 2 to 3 weeks to germinate. When the seedlings grow to about 10 cm, it takes about 70 days to plant.
For seedling cultivation in plug trays, mix peat and vermiculite at a ratio of 3:1 before sowing. Cover with a thin layer of vermiculite and water thoroughly. A small arched shed is built on top, and the seedlings are then managed with the same local methods.
The difference is that after the rosemary emerges, the plug tray should be moved frequently to prevent the roots from penetrating into the ground along the holes below the plug tray and damaging the roots during planting. If the tray is placed on a shelf, this is not necessary.
The bud rate of rosemary is very low, generally only 10% to 20%. Moreover, in the first year, the growth of rosemary is extremely slow. Even in autumn, the size of the plant is smaller than that of the plant when it was first planted. Not much more. It will take 2 to 3 years to achieve mass production, which is very slow.
Therefore, asexual reproduction is generally used in production.
However, those cultivated from seeds have a more fragrant smell, so the propagation method used depends on the needs.
2. Propagation by cuttings
It is mostly carried out from winter to early spring. Select fresh and healthy stems that are not completely lignified as cuttings, and cut them about 10 to 15 cm from the top. Remove about 1/3 of the leaves below the branches and insert them directly into the medium.
Keep the medium moist. Roots will take place in about 3 to 4 weeks. After 7 weeks, they can be planted in the open field. The minimum night temperature for cuttings is 13 degrees Celsius.
3. Layering propagation
Taking advantage of the characteristics of rosemary stems that can produce adventitious roots, bend the branches of the plant close to the ground and cover them with soil, leaving the top in the air to wait for growth. New roots are cut from the parent body to form new individuals and colonized in the open field.
The role of rosemary can be said to be very wide. Keeping a pot of rosemary at home can not only beautify the environment and purify the air, but also help enrich the dishes when cooking. It can be said that its uses are Very broad.
