Propagation methods of dragon fruit

Dragon fruit is a common tropical and subtropical fruit with flesh like sweet cream but covered with small black seeds. The texture is mild and the taste is delicate. So what are the breeding methods of dragon fruit?

I. Cuttage

The most suitable planting time is in spring. The stem nodes with full growth are selected and the segments of 375px are cut off. After the wound is air-dried, it is inserted into the sand bed or cut directly under the support frame and on the side of the cement column. After cutting, there is no need to water, to maintain the dryness of the soil. The watering will begin in 10 days. It can take root in about 15-30 days, and when the root grows to 3-100px, it can be transplanted into the seedbed.

2. Grafting

Choose "measuring Tianyi", which is disease-free, robust and full of stem and flesh, as the rootstock and carry out grafting on a sunny day. The stem of dragon fruit was cut into the plane with a knife, the scion was inserted into the cambium, and fixed with cotton thread. Under the condition of 28-30 ℃, a large number of calli were formed on the wound joint surface in 4-5 days, and the color of the scion was similar to that of the rootstock, indicating that the vascular bundles of the two were healed and grafted successfully, and then could be moved into the pseudo-planting seedling bed to continue cultivation.

1. Selection of rootstock and scion

The yellow meat type dragon fruit rootstock can choose the wild triangle column (Bawanhua) and so on, and the red meat type dragon fruit can choose the white meat type dragon fruit as the rootstock. Choose a 1-2-year-old triangular column, cut off from the stem node from the mother, cuttage in the sandy loose soil (the depth is suitable), build a shade shed, pour through water can be used as rootstock, about half a month after cutting can be grafted. The scion is suitable for the branches with better development in the same year.

two。 Grafting time

Generally, except for the low temperature period in winter, it can be grafted in other seasons. Because of the long cold and wet time in winter and spring, the wound is not only difficult to heal, but also enlarges and endangers the plant. Therefore, it is best to choose the grafting time from March to October, so that there is a full healing and growth period, and is conducive to the hanging fruit in the coming year.

3. Drug treatment before grafting

The knives used for grafting are sterilized with alcohol or liquor to prevent bacterial infection. It is available conditionally. Dipping sodium naphthalene acetate solution into the base of scion can not only promote the formation of callus, but also improve the survival rate.

Third, potted sowing

The germination temperature of dragon fruit seeds is about 25 ℃.

To choose the culture soil with fine particles, you can also use the sowing soil sold in the market instead.

Be sure to remove the pulp and gum attached to the seeds, otherwise it is easy to grow mold when germinating.

To make a small potted plant, the seeds should be spread more closely, especially at the edge, otherwise they will lose their sense of beauty.

If the basin does not have a bottom hole, do not use a kettle directly to avoid overwatering. Spray water with a spray can once every 2-3 days.

Dragon fruit common breeding methods on these, we can according to the actual situation, choose the most suitable for their own breeding methods.
