1、 Cutting method of Catharanthus roseus

1, prepare the matrix: prepare the bottom sand or coarse river sand of the fish tank, pour the bottom sand into the foam box, add fresh water and wash it repeatedly, then pour into the diluted Potassium Permanganate solution (add water diluted to lavender, as shown), and the water is not 1cm. p>

2. Cutting cuttings: select the strong growing stems and leaves of Catharanthus roseus, cut several small segments as cuttings, each of which is 5-10cm long. Remove the lowest leaves of the cuttings and take them directly for cutting without drying the wound

3. Start cutting: insert the treated cuttings vertically into the bottom sand. Be careful not to insert them upside down or to the end. Leave rooting space at the lower part of the cuttings. After cutting, put them in the astigmatism place. There is no need to manage them or move them all the time

4, after maintenance: after the cuttings are finished, put the foam box at the temperature of 25 degrees Celsius. When the water in the foam box is dried up, it will take root almost 2 weeks or so. If the curing temperature is low, the rooting will be slower. p>

5. Transplanting and colonization: when the root system grows to 2cm, pull out the cuttings from the bottom sand and transplant them into the basin soil. Pour water into the basin at the place where the water is permeable and the light is diffused and ventilated. After the plant has an obvious growth trend, gradually increase the light, and then gradually replace the large basin with the growth of the plant

2、 How does Catharanthus roseus take root in hydroponic culture

It is very simple to cultivate the roots of Catharanthus roseus in water. Just cut the branches of the plant into cuttings with a length of 5-10cm, insert the cuttings into the water, and replace the water every two days until the roots of Catharanthus roseus come out of the water
