How to raise rosemary? Breeding points and Culture methods of Rosemary

Rosemary is a common herb that emits a pleasant aroma and enhances memory and freshness. At the same time, rosemary has good industrial value, medicinal value and edible value, so it has attracted many friends to plant it. So how do you raise rosemary? The breeding points and culture methods of rosemary are briefly introduced below. Let's learn about it.

First, the breeding site of rosemary

1. Sowing: generally speaking, seedlings are cultivated in greenhouse in early spring. Seedlings can be cultivated by soil methods or seedlings, but the germination rate is very low, usually only 10-20%, while in a good year, rosemary grows extremely slowly, even if it is the size of a plant. Autumn is not much bigger than the plants just planted, and mass production will be slow in 2-3 years. Therefore, asexual reproduction is generally used in production. However, when seeds are planted, the smell is better, so breeding methods should be determined according to needs.

two。 Insertion: Rosemary cuttings are mostly carried out from winter to early spring. Choose fresh, healthy and partially lignified stems as cuttings. Cut about 10-15 cm from the top and remove about 1x3 leaves under the branch. Directly inserted into the medium, the medium remains moist, rooting will take root within 3-4 weeks, and can be planted in the open field after 7 weeks, with a lower night temperature of 13 degrees Celsius.

3. Beads: Rosemary stratification mainly uses the characteristics of rosemary stems to produce adventitious roots. Branches near the ground bend and cover the soil, leaving the top in the air, growing new roots, cutting from the matrix into new individuals and planting them in open fields.

Second, the propagation method of rosemary.

1, site preparation: before rosemary transplanting, the flat land should be beaten to the pond according to the plant distance, apply a small amount of base fertilizer, and then cover the base fertilizer with thin soil, and then transplant. Generally speaking, the seedlings transplanted in the field are the mother plants that have been transplanted to the roots. The row spacing of the transplanted plants is 40 × 40cm, and the number of plants per acre is 4000-4300. The planting season is in the central and southern regions of Yunnan Province all the year round, and it is better in spring and autumn.

two。 Planting: it is better to plant rosemary on cloudy, rainy and sunny days. After transplanting, you should pour in the root water. When pouring water, you should not dump the seedlings. If there is a lodging, it should be stabilized in time. After 5 days of planting, rosemary is well poured in (depending on the dry and wet conditions of the soil). Watering can be reduced after the seedlings survive. If dead seedlings are found, they should be replanted in time. When planting, there should be a straight line between the pond and the pond for ventilation.

3. Fertilization: Rosemary is more resistant to ridges. According to the different soil conditions, a small amount of compound fertilizer was applied after cultivation and weeding. After fertilization, the fertilizer should cover the soil. After each harvest, the available fertilizer was applied to nitrogen fertilizer and phosphorus fertilizer. Mainly, generally 15 kg of urea per mu, 25 kg of calcium phosphate.

4. Pruning: rosemary can be trimmed 3 months after planting. Excessive shearing usually prevents plants from germinating again. It is safer not to exceed half of the branch length at a time. Although rosemary plants have small buds in each leaf aphid, these axillary buds will develop into branches as the branches grow in the future. When growing up, the whole plant will not only appear messy because of the branches, but also affected by poor ventilation. Insect pests, so regular pruning is very important.

5. Harvest: Rosemary can be harvested for many years, mainly through branches and leaves, and can be folded with scissors or directly. However, special attention must be paid to the fact that the juice of the wound will soon turn into glue and is difficult to remove. Therefore, gloves must be worn and high imitation clothing with long sleeves should be worn. The amount of harvest can be regarded as a growth condition, usually 3-4 times a year, with each harvest of at least 250-350 kg / acre.

Rosemary likes warm and humid climates and is more resistant to drought. As a result, the planted soil is rich in sand and well drained. It is more conducive to growth and development and requires special care in the curing process. Above, we introduced the breeding sites and training methods of rosemary, hoping to be helpful to you!
