The latest cutting method of Platycodon grandiflorum

Platycodon grandiflorum is very popular in China, so its planting area is also very large. When planting Platycodon grandiflorum, reproduction is essential. In fact, Platycodon grandiflorum can not only sow and propagate, but also carry out cutting propagation. However, because many people's cutting methods are wrong, the survival rate is relatively low. So how to cut Platycodon grandiflorum in the end? Today, the editor brings you the cutting method of Platycodon grandiflorum. Let's have a look!

1. Cuttings selection

Before cutting Platycodon grandiflorum, we should first select the cuttings. The cuttings should select the branches with strong meristematic ability from the Platycodon grandiflorum plant, and it is best to choose the stem under the heart leaf after jointing. Branches should be free from wounds, diseases and insect pests and grow healthily. Do not choose too delicate stem, because the delicate stem is not yet fully mature. Also need a lot of vegetative growth, will not only increase the cost of breeding, the survival rate will also be relatively low. Therefore, the choice of cuttings is very important, if possible, it is better to have only two leaves on the cuttings, so that the survival rate will be higher.

2. Cuttings treatment

After selecting the cuttings, cut the cuttings obliquely into small pieces. A pair of leaves should be retained on each segment, while oblique shears mainly increase the meristem area of cuttings. Then cut off the leaves on each segment by about 1 / 2 to avoid consuming too much nutrition. Because at the beginning of cutting, there is no root, so there is no nutrition. Growth nutrients are also stored before cuttings, so cutting the leaves of 1 to 2 can reduce nutrient consumption and increase rooting rate. However, it should be noted that all the leaves should not be cut off, otherwise the photosynthesis of cuttings can not be carried out, and the lack of nutrition will lead to the failure of cutting.

3. Matrix preparation

The substrate of Platycodon grandiflorum is also very important, and the cutting substrate directly determines the survival rate of Platycodon grandiflorum cuttings. The cutting substrate should be kept in a partial alkali state, and the PH value should be controlled at about 6. Can be prepared with peat, vermiculite and other substances, and then add some carbendazim for disinfection to avoid carrying bacteria and affect the normal growth of cuttings. Then before cutting, we should pay attention to properly watering the substrate, so that the substrate in a wet state, but also more conducive to the rooting of cuttings.

4. Cutting method

Before cutting, now there are several small holes in the cutting substrate, and then the cuttings are carried out, and then the substrate is compacted and watered. Then the film should be covered, and several small holes should be pierced in the film to ensure its permeability. If it is a potted plant, put it in a bright and low temperature place after cutting, and you don't need sunshade in winter and spring. The film can be removed in about ten days and take root in about a month. When the local part of the new bud grows the fourth leaf, it can be transplanted and planted for normal maintenance.

The above is a brief introduction to the cutting method of Platycodon grandiflorum. That's all for today's introduction. This article is for reference only. I hope it can help you all.
