A brief introduction to the culture methods of how to raise rose flowers

What are the breeding methods of Chinese rose? Love rose more than other flowers, her shyness and softness are arrogant peonies, lofty daffodils, flamboyant roses can not match, she quietly open, in the early summer bud, quietly blooming. Rose flowers should be watered with moderate dryness and humidity. Rose flowers have strong cold tolerance, can withstand a low temperature of-10 ℃, and like plenty of sunshine. Let's take a look at the breeding methods of rose flowers.

I. Culture methods of rose flowers

1. Selection of flowerpots for rose culture

The flowerpot used for cultivation had better be permeable and breathable, and the ordinary mud basin is better, with exquisite ceramic pots to increase beauty. It is best to soak the new mud basin with water before use. The seedlings that just survived were planted in small flowerpots of 15 centimeters, and those of 2-year-old seedlings were planted in pots of 20 kilometers. later, the large pots were gradually replaced with the growth of the plants.

two。 Selection of potted soil for rose culture

Rose flowers like fertile and moist soil, afraid of drought and stagnant water, we must choose sandy loam with loose soil, rich organic matter, good drainage, ventilation, water conservation and fertility. The acidity and alkalinity can be planted in the range of pH 5.6, but the slightly acidic to slightly alkaline soil of 6.8murmur7.2 is better. 5 parts of garden soil, 3 parts of garbage soil, 2 parts of rice chaff ash and proper amount of vegetable cake can be used in the culture soil. Or use 4 parts of horse dung, 4 parts of garden soil, 2 parts of river sand, plus a small amount of vegetable cake and bone meal.

3. Temperature requirements for rose culture

Potted rose flowers can survive the winter safely indoors. Pay attention to cooling in the hot season. The most suitable temperature for rose flowers is 18 Mel 20 ℃, so the flowers blooming in April-May and 9 Mel-October are large, colorful and fragrant. When the temperature is more than 25 ℃, the growth rate is faster, but the flowers are not durable; in the high temperature and humid climate of more than 30 ℃, not only the flowers are small, less, light color, light fragrance, but also prone to various diseases and insect pests. Under high temperature and dry conditions, deciduous leaves will dormancy and stop growing and flowering. Above 5 ℃, it can continue to grow and blossom, but very slowly. Below 5 ℃, it stopped growing and was in a dormant state.

4. Light requirements of rose culture

Chinese rose is a positive plant, like plenty of sunshine, the daily light should not be less than 5 murmur6 hours, otherwise the branches and leaves are weak, grow only, the flowers are bad, and the flowers are not colorful. It is generally appropriate to put it in a place with sufficient light, but if you put it on the concrete floor of a high-rise building, you should pay attention to proper shade and sun protection at noon in summer.

5. Watering method of rose culture

Rose flowers should be watered with moderate dryness and humidity. When new branches and leaves grow in March, they are watered once every two days and carried out in the morning. When forming buds in April, water them once a day. After entering the flowering period in May, the pot soil is too dry and wet, which will cause falling flowers. Generally, it will be watered once at about 8: 00 in the morning, and then irrigate an appropriate amount of water as appropriate. Grasp the principle of "no dry, no watering, watering thoroughly". The leaf surface needs to be cooled by spraying water frequently in summer.

6. Fertilization methods for rose culture

Grasp the principle of "applying thin fertilizer frequently" and avoid applying raw fertilizer and thick fertilizer. Applying a little organic fertilizer to the roots in winter can enhance the ability of overwintering cold resistance. Before sprouting in early March, high concentrations of liquid fertilizers such as mature human feces and urine, bean cakes, chicken and duck dung, fish offal and so on can be applied. When the bud is ready to bloom, add one more light liquid fertilizer. After the flower fade in summer and before the axillary bud is developed, a medium concentration of mature liquid fertilizer can be applied to promote a large number of blossoms in autumn.

Potted rose flowers can be fertilized properly, mainly cake fertilizer, 50 grams for annual plants, 70 grams for 3-year-old roses, and 100 grams for 4-5-year-old roses. Thin liquid fertilizer can also be applied in the growing season, such as rotten horseshoe water, sesame paste residue water, chemical fertilizer dilute solution and so on.

7. Matters needing attention in rose culture

If the temperature difference is large, the sun-dried water should be selected when watering, so as to reduce the temperature difference between basin soil and water, avoid overcooling of water and stimulate root development.

If you are not going to harvest flower seeds, it is best to cut off the residual flowers before they bear seeds.

If excessive fertilization causes leaf burning, it should be watered immediately.

8. Propagation methods of rose culture

Sexual reproduction is often used to cultivate new varieties. In family cultivation, the method of cutting and grafting is simple and easy, and it is widely used.

Most of the cuttings were carried out above 15 ℃ in spring or in early summer or early autumn. In order to improve the survival rate, ring peeling can be carried out on the plant, and then the branches can be cut off after the callus is produced.

Grafting is the main means of propagation of Chinese rose. Choosing the right rootstock is the key. At present, the commonly used rootstocks are wild rose, pink rose and so on. Grafting is carried out in the dormant period, and branch grafting is often used. From December to February in the south, and before the leaf buds sprout in spring in the north. In the growing season, the management should be strengthened after bud grafting. (can the above content about how to raise rose flowers solve the problem for you?
