Rose cutting in water
A little plant knowledge, introducing the knowledge of rose China rose, rose cutting in water, the following share detailed content.
Rose cutting in water is a commonly used method for rose friends to propagate roses, which has the advantages of simple operation, hygiene, time-saving and labor-saving. However, some rose friends are not very familiar with rose cutting in water. This article is a brief introduction of the propagation method of rose cutting in water, which is very helpful to rose friends.
1. Season and temperature
Propagating roses by water cutting can be carried out from spring to autumn, and the best results are obtained when cutting in spring and summer, or in late summer and early autumn. The suitable temperature is between 20℃ and 30℃, and the water temperature is between 15℃ and 25℃. If it is lower or higher than this range, it can adjust the light to make it close.
2. Preparation and treatment of cuttings
The branches of roses cut in water should be selected from sunny plants, annual healthy branches without diseases and insects, full development of tissues, and not yet germinated, located between 3 to 5 leaves under the flowers. Each cutting should have 2 to 3 internodes, cut 10 to 12 centimeters long, cut obliquely about 3 millimeters above the top bud, and cut flat 1 centimeter below the bud at the bottom. Cut the base 0.5 centimeter in a circle with a sharp knife, peel off the outer bark to expose the xylem, to prevent the infection of the xylem by bacteria and cause rot. Leave 2 pinnate leaves at the top of the branch and cut off the top 2 small leaves to facilitate healing and rooting, and insert immediately after treatment.
3. Water cutting tools
The container for cutting roses in water can be made of plastic or glass, and the size of the container opening is determined by the number of cuttings. If 1 to 2 cuttings are inserted, a 250 ml wine bottle or medicine bottle can be used. If 3 to 4 cuttings are inserted, a 500 ml wide-mouth bottle (or cup) should be used, and a glass jar can be used for a large number of cuttings. Before cutting, select a piece of foam plastic about 1 to 2 centimeters thick as a water floating object, and the floating object depends on the size of the container. After selecting, make a hole with a diameter of about 0.5 centimeter for the cutting with a bamboo skewer, insert the cutting into the hole, and the depth of the cutting in the water should be 2 to 3 centimeters, no matter what kind of container, fill the container with 2/3 water, and float the foam plastic fixed with the cutting on the water surface. The container must be disinfected with potassium permanganate solution before use to prevent bacteria from invading and causing infection at the incision, which can lead to failure.
4. Water selection
The water used for rose cutting in water includes cool boiled water, tap water, river and pond water, well water, etc., with cool boiled water being the best; if tap water is used, it is best to store it for 2 days to allow the chlorine in the water to volatilize. After the water is poured into the container, the processed rose cutting is inserted into the water. Then observe frequently, and when the water level is insufficient, supplement it with cool boiled water or well water of the same temperature to the required water level. Generally, change the water every 3 days. For large containers such as basins, large wide-mouth bottles, goldfish tanks, and water tanks, change the water every 10 days or so to keep the water clean and conducive to growth.
5. Light treatment
During the cutting period, if the temperature is not high, it can be exposed to full or half-day light, which can increase the temperature of the medium and enhance the photosynthesis of the leaves. If it is very hot in summer, due to strong sunlight and high temperature, it is not conducive to survival, so it should be placed in a shaded area outdoors or in a cool and ventilated room to prevent the water temperature from being too high and prevent the incision from rotting and turning black.
6. Post-cutting treatment
Every two weeks, spray 1:1000 urea or potassium dihydrogen phosphate solution to promote early rooting of cuttings. Generally, there will be no disease, if a large area of propagation is prone to aphid infestation, you can spray 1 time of 0.1% dimethoate solution to kill. To save labor, you can put a particle of copper sulfate in the container water of the cutting, which can reduce water change or unnecessary water change.
7. Survival and planting
If the temperature is suitable, the incision will heal about 3 weeks after cutting, and the roots will start to grow after 1 month, indicating that the cutting has survived. When the roots are about 2 centimeters long, they should be taken out and planted. If the roots are too long, the roots will turn from white to yellow, or even rot. Since the new roots are fragile and easy to break, planting must be careful. If potted, first fill the pot with soil, preferably using culture soil at the bottom and topsoil at the top, pour plenty of water. After the water stops flowing from the bottom of the pot, level the soil slightly and make a hole in the center of the pot, about 1/2 the length of the cutting and 5 to 6 times the diameter of the cutting. Then put a little dry fine sand at the bottom of the hole, followed by putting the seedling in the center of the hole with one hand and filling the gap with dry sand with the other hand. No need to water, it can be moistened. First place it in a shaded place for 7 to 10 days, and then gradually increase the light, and transfer to normal management.
