Cutting Seedling technique of Rose

Rose is a combination of ornamental, medicinal and edible, with the effect of awakening depression and relieving spleen, promoting blood circulation, beauty and beauty, and has a special effect on the treatment of cardio-cerebrovascular diseases. With the improvement of people's living standards, the market demand for roses is increasing, especially in recent years.

The existing rose planting methods include sowing method, cutting method, grafting method, pressing method and split method, mainly by cutting method. The roses with leaves were cut in sandy soil after being treated with growth hormone, but the existing methods have some problems such as low survival rate.

In the method of rose cutting propagation, callus can be formed in 7-10 days, roots can take root in 10-15 days, the root system can reach 1-3cm in 18-25 days, and the survival rate is more than 85%.

1. The rose branches were collected from mid-February to mid-March, and the cuttings were cut obliquely, leaving 4 buds for each cutting. the uppermost bud was 1.5 cm from the top cut, and the cutting length was 30cm.

3. The nutrient matrix is made of the following raw materials by weight: 20 parts of peat, 20 parts of perlite, 10 parts of vermiculite and 20 parts of perlite. The nutrient matrix is disinfected with a KMnO4 solution with a mass concentration of 0. 5%, and then put into a cutting container. The height of the nutrient matrix accounts for 2% of the height of the cutting container

4. The treated cuttings obtained in step (2) are inserted into the nutrient substrate of the cutting container, the insertion depth is 5cm, watered through, and placed in the plastic film arch shed, which is covered with double-layer sunshade net, the temperature in the arch shed is 25 ℃, the air humidity is 45%, and the soil pH is 5. 5.
