Last Updated: 2024/12/23, Perfume rose is a plant of the genus Rosa, which is suitable to grow in an environment with plenty of sunshine and air circulation. It is not strict with the soil, but attention should be paid to the following links in open field cultivation. First, the cultivation area. Perfume rose is a light-loving plant. In the process of cultivation, you should choose sunny ground and avoid planting in the shady side of tall buildings, trees and hillsides. The ideal soil for cultivating perfume rose should have good aggregate structure and rich content of organic matter. Perfume rose does not require high soil acidity and alkalinity, on the soil with a pH value of 5.5 to 8.0.

Perfume rose is rose plant, suitable for sufficient sunshine, air circulation in the environment of growth, it is not strict with the soil requirements, but in the open field cultivation should pay attention to the following links.

1. Cultivation area. Perfume rose is a light-loving plant. In the process of cultivation, it is necessary to choose sunny land and avoid planting beside tall buildings, under trees and on the shady side of hillsides. The ideal soil for cultivation of rose should have good aggregate structure and rich organic matter content. The requirement of soil pH is not high, rose can grow on soil pH value of 5.5~8.0, but it grows best in slightly acidic soil pH value of 6. Most of the roots of rose are concentrated in the 30 cm ~40 cm deep soil layer, so the depth of tillage layer should be 50 cm ~60 cm.

2. Fertilizer selection. Perfume rose like fertilizer, especially like organic fertilizer, such as manure, compost and so on. Organic fertilizer was applied at a rate of approximately 150 kg per 10 plants. The flowering period of Chinese rose is long, so chemical fertilizer should be applied during its growth process to obtain quick effect. The ratio of nitrogen, phosphorus and potassium in topdressing should be 1:1:2 or 1:2:3. The chemical fertilizer frequently used is calcium superphosphate, which is applied at an average of 2 kg per 100 m2.

3. Planting plant spacing. The plant spacing of Perfume rose varies according to the cultivation purpose. For breeding or scientific research, the plant spacing is often 150 cm ×80 cm; for parks, flower shops, streets, factories and mines to beautify the environment, it is necessary to adapt to local conditions, using a wider row spacing. Before planting, the seedlings should be trimmed once, cutting off damaged branches, diseased branches, weak branches, damaged or too long roots should also be cut off. When planting soil humidity should be appropriate, such as too wet should delay planting, soil drying for a few days before transplanting; such as too dry, should be 2 days to 3 days in advance irrigation once permeable.

4. Water management. Water management is also an important task for rose. Insufficient or excessive water will inhibit its growth and development, which needs to be adjusted according to its different growth and development stages. Spring and autumn is the peak flowering period of rose, this time water supply should be sufficient; in rose plant pruning, in order to control plant growth, should suspend watering, pruning after appropriate increase in watering. In addition, if it is cultivated in sandy soil with poor water conservation, the number of watering times should be appropriately increased; poor drainage soil, watering should be careful to prevent rotten roots.

5. Trimming and shaping. Pruning is to allow as many strong branches as possible to germinate, in order to improve the quality of flowering. In addition, pruning can also make the tree complete and balanced, so that it is in harmony with the living space. The best time to prune is when the plant stops dormancy and is about to sprout, or when it stops growing and is approaching dormancy. There are three types of pruning: light pruning, moderate pruning and heavy pruning. Mild pruning is to cut short the healthy branches and remove the inward expanding buds; moderate pruning is to cut off the first annual healthy branches at the base or cut off half; heavy pruning is to leave only 3 ~4 annual branches of the whole plant, and then cut short 20 cm above the ground. For newly transplanted plants that have been pruned prior to planting, pruning is not necessary during the first year of planting. After a year, can be cut off the root growth of thin and cross branches together, leaving strong branches should be cut off at least half the length. The roses planted more than 3 years old still need to be pruned every year to keep the plant perfect.

VI. Winter maintenance. In areas where the lowest temperature in winter is below minus 15 ° C, some anti-freezing measures should be taken. Such as in the plant base heap 20 cm of soil, or plants with straw curtains, hemp bags, plastic film, etc. wrapped up. In areas where the lowest temperature in winter reaches-20 ℃, it is necessary to dig up the soil on one side of the plant, put the plant down and cover it with soil.
