The most common method of propagation of Brassica is cutting. There are two kinds of cutting methods: column cutting and Twig Cutting.
The trunk with a diameter of 6cm to 10cm shall be used for cutting, and it is OK to cut more than 10cm, but to keep the trunk fresh, the color of several skins shall be light yellow; the soil shall be about 30cm deep; the substrate shall be disinfected before cutting; the depth of the trunk inserted into the soil shall be about 10cm to 25cm, which can be adjusted according to the firmness of the trunk; if the height of the trunk is high When the degree reaches more than 1 meter, other main types can be used to fix the cuttings for their firmness. When cutting, we should keep the soil moist and gentle, and also avoid the sunshine around noon. After cutting, we should water it in time, and we can see the new buds in about a month. When the new buds grow to 5cm to 10cm high, we can plant.
This method can be combined with the pruning of plants. The pruned branches can be cutted. When the plants grow to a certain height, some of the high branches must be cut for cutting. Before cutting, the branches should be cut to a proper length before cutting; before cutting, all kinds of soil containers and tools should also be disinfected to avoid causing diseases to the branches. When cutting, you can choose to cut horizontally or vertically. In the temperature range of 25 ℃ to 30 ℃, you can grow new roots in about a month.
