The course of the latest three Seedling raising techniques of Dragon Fruit

The dragon fruit has a good taste, sweet and juicy taste, rich in nutrients, rich in plant protein and anthocyanins, as well as vitamins and water-soluble dietary fiber, with the role of beauty and anti-aging. And if you want to grow dragon fruit, how to raise seedlings? Next, let's take a look at the three major seedling techniques of dragon fruit with the editor.

1. Cuttage seedling

First of all, you need to prepare a cutting bed. You can fill a wooden box with 15-20 cm of clean river sand, or use dregs and 30% charcoal powder as the substrate. After the cutting bed is prepared, about 30 cm of dragon fruit branches and leaves are cut as cuttings, and after cutting, they are naturally air-dried in a cool place. after about 7-10 days, the wound naturally heals and chooses the appropriate cutting time for cutting. this can reduce wound infection and decay, and the rooting rate is more than 95%. It should not be watered immediately after cutting, and water should not be watered 10 days after planting.

2. Grafting and raising seedlings

If the dragon fruit uses the method of cutting seedlings, then its growth and development may be poor, and in order to obtain high and high yield, it is necessary to use grafting propagation. Generally, the plant of 1-2 years is selected outside the air temperature period in winter, and cut off from the stem node and cut in the sandy loose soil. After setting up the sunshade, it can be used as a rootstock, and grafting can be carried out after the cuttage survives. It is appropriate to have a branch that grows well in the same year.

3. Tissue culture and propagation.

Tissue culture and propagation is to rinse the tender stems of dragon fruit with a little soapy water, cut them into 3-4 cm segments in a sterile environment, disinfect them with alcohol for 30 seconds, then disinfect them with 0.1% mercury solution for 10 minutes, and absorb the surface water dry. Then under aseptic condition, the stem node containing thorn seat was cut into 2cm X 2cm and inoculated on bud induction medium, and a large number of tissue seedlings could be cultivated after growing small buds. The process of weaving and raising seedlings is complicated, the rooting is not good and the growth rate is slow, so it is rarely used in production.
