Introduction and characteristics of Chinese roses
For many girls, the introduction and characteristics of Chinese roses and the small green plant maintenance experiences of planting Chinese roses, if there are any mistakes, welcome to correct!
(1) Propagation methods of Chinese roses
① Seed propagation. Seed propagation is used in the cultivation of new varieties. Collect seeds in autumn and place them in a plastic mesh bag filled with moist sand, then store in a 4℃ environment. After 40~60 days, when the seeds crack and germinate, they can be sown. Transplant when the seedlings have 3~5 small leaves.
② Grafting.蔷薇 is commonly used as the rootstock. It is usually carried out from June to September, and the grafting site should be as close to the ground as possible. Make a "T" shaped cut on the side of the rootstock stem with a bud grafting knife, select a bud from the middle of a healthy branch of the Chinese rose, insert the bud into the "T" shaped cut, and tie it with a plastic strip. It can heal in about two weeks, and the survival rate of bud grafting is relatively high.
③ Cutting. In early spring or late autumn dormancy, cut mature branches with 2~3 buds for cutting. If using young branches for cutting, they should be shaded appropriately and the seedbed kept moist. Generally, roots can form within 30 days after cutting. If rooting powder is used to dip the branches during cutting, the survival rate is high.
(2) Key points of Chinese rose maintenance
① Soil. For open-field cultivation, choose a place with high terrain, abundant sunlight, and good air circulation, and slightly acidic soil. Deeply turn the soil and apply organic fertilizers as a base fertilizer during cultivation.
② Sunlight. Chinese roses love light and require abundant sunlight to grow vigorously and bloom continuously.
③ Watering. The watering of Chinese roses varies with the seasons. In the north, water thoroughly before the ground freezes to keep the soil moist during the winter dormancy period; after the ground thaws in spring, water thoroughly to help the buds germinate and the branches grow. Increase watering during the growing season and flowering period, but avoid watering in the summer sun.
④ Fertilization. Chinese roses enjoy fertilizer, and continuous blooming also requires sufficient nutrition. Potted Chinese roses should be fertilized frequently, with a dilute fertilizer water applied every 10 days during the growing season. The base fertilizer should be mainly slow-release organic fertilizers, such as decomposed cow dung, chicken manure, soybean cake, and oilcake. No fertilization is applied during the winter dormancy period.
⑤ Pruning. In addition to winter and spring pruning, the branches and leaves should be pruned promptly throughout the growing season. After the flowers fade, the残花 and upper branches should be cut off promptly to promote the early growth of new branches and reblooming. If there are branches that grow particularly strongly, they should be trimmed appropriately to avoid consuming too much nutrition and affecting the growth of other branches. In summer, when the growth is too dense, it should also be pruned appropriately.
⑥ Preventing diseases and pests. Prevent diseases and pests in a timely manner. The main diseases and pests of Chinese roses include black spot disease, powdery mildew, leaf blight, golden龟子, and刺蛾, among others. Preventive measures should be the main approach, and fungicides can be sprayed regularly during high temperature, high humidity, and rainy seasons. In the winter dormancy period, drugs can be sprayed appropriately as needed.
