1、 Selection of cuttings

Cuttings are the branches used for cutting, which affect the survival rate of cutting. Generally, branches with healthy buds, full internodes and no signs of overgrowth are the best

Semi hard wood branches are generally selected for family cutting. The selected branches are annual, fuller than newborn branches, not afraid of water loss and easier to survive

2、 Keep appropriate blades

Good cuttings should have at least three nodes in addition to the appropriate length (10 ~ 15 cm), and appropriate leaves should be retained and trimmed locally. Retaining leaves can not only avoid excessive loss of water, but also provide nutrients produced by photosynthesis for cuttings and promote cuttage life

Cutting in autumn and winter, because the environmental temperature is low, the water of cuttings is not easy to lose. Under the appropriate temperature environment, the,. In addition to removing the lower leaves that affect the growth, all the upper leaves can be retained. Cutting in spring and summer. The exchange rate is high, and the cuttings are easy to be short of water. At this time, the part of the leaves can be trimmed or cut half

3、 Keep it clean and sterile

Cutting is all the equipment used. Such as planting forceps, soil and containers should be cleaned to ensure no pollution. Soak in diluted alcohol or bleach before use. The blade or scissors used for cutting branches should be disinfected when cutting each knife, so as to reduce the possibility of bacterial infection

4、 Appropriate season

Generally speaking, the season suitable for cutting is between spring and summer. At this time, the air humidity is high, the branches are not easy to lose water, and the temperature is high, so it is easy to survive cutting

Of course, cutting can also be carried out in autumn and winter, but because of the low temperature environment, the growth of branches is slow and the weather is relatively dry. When cutting, it is necessary to be prepared for heat preservation and moisture preservation to promote the rooting of branches

5、 Ventilation and proper light

When cutting, ensure good soil permeability and sufficient light. It has a certain water holding capacity, ensures a humid environment, and the air permeability is conducive to hair roots. Therefore, the cutting medium often adopts pearl stone, vermiculite, etc

Maintaining high humidity can ensure that the branches do not lose water. Before rooting, the humid environment can prolong the life of the branches and win more rooting time for the branches. Before rooting, we should avoid direct sunlight and give appropriate light to ensure that the leaves carry out photosynthesis and accumulate certain nutrients

6、 Application of rooting powder

Some plants are not easy to take root. In order to improve the survival rate of cutting and shorten the time of rooting, rooting agents on the market can be used to promote root germination. You can dilute the rooting powder and soak the branches

7、 Yellowing treatment

That is what we often call shading treatment. We use black tape and black paper to put the branches in a completely black environment, or select some healthy branches for yellowing treatment. After yellowing branches, the epidermis will thicken and the internal cells will increase, which is conducive to rooting

8、 Engraving treatment

The cutting treatment is aimed at plants that are not easy to root. Choose strong branches and make wounds at the base of the branches. After the cut parts grow, cut the branches and cut them for cutting, which can improve the survival rate

9、 Branch selection after pruning

Many plants will naturally age after growing for a period of time, which reduces the survival rate of cutting. Therefore, while selecting branches, cut off 1 / 2 of the branches to promote their re germination. The new branches from the aged branches have strong growth ability and can be used for cutting

10、 Temperature control of root

For professional cutting propagation, people will shorten the rooting time of cuttings and improve the survival rate of cuttings by increasing the root temperature. The soil temperature of the root will affect the physiological response of the plant. Appropriately increasing the soil temperature is a good method
