Its cutting time should be determined according to the cultivation environment.If it is cultivated in open field, it can be carried out between the end of April and the first ten days of May.If the greenhouse is cultivated in autumn, it can be carried out from the end of June to July.If greenhouse cultivation, cuttings can be started in August.
1. Selection of cuttings: When cutting, branches with strong disease resistance, vigorous growth and no pests and diseases should be selected, with a length of 15-20 cm and about 4-5 nodes.After the interception, the lower leaves are cut off, leaving three or four in the middle and upper parts.
2. Prepare soil: Prepare suitable soil to ensure looseness, drainage and good fertility.It can be mixed with garden soil and decomposed organic fertilizer, then mixed with appropriate amount of lime, and disinfected to ensure asepsis and no insect eggs.
3. Cuttage soil: After the cuttings are treated and the soil is prepared, the cuttage can be carried out.When inserting, pay attention not to be too deep, about one third of the inserted cuttings, that is, the depth is between 3-4 centimeters.
4. Management after cuttage: After cuttage, water should be sprayed to keep wet, and then an arch shed with appropriate size should be built and covered with plastic film, so as to keep warm and wet, and also to shield strong light, so as to take root faster, and to improve the possibility of survival, so that new roots can grow soon.
