The propagation method of human pistachio

Pistachio was originally a tropical fruit in America, but now it also has a certain cultivation area in tropical water such as Guangdong and Yunnan in China. It gets its name because the fruit of human pistachio looks very much like the human heart. The nutritional value of pistachio is very high, so the planting area is also expanding. So how do we breed when we plant pistachios? The following editor has brought you the breeding method of pistachio, let's have a look!

1. Sowing and reproduction

Sowing and reproduction is the most basic reproduction method of pistachio, and the ripening time of pistachio is about September every year. After the fruit is ripe, take the seeds out of the fruit and pick out the dried-up, cut seeds. Wash the slime pulp on the surface of the seed coat with clean water for the remaining seeds. Then dry the seeds in the shade and store them in a ventilated place to prepare for sowing the following year. Before sowing, attention should be paid to the work of accelerating germination and disinfection so as to improve the germination power of seeds. When sowing, it is best to control the temperature after 25 degrees, and then strengthen the management when the temperature is appropriate. Generally, it can sprout about a month after sowing.

2. Cuttage propagation

Cutting propagation is best carried out in summer, because the temperature and humidity in summer are more suitable for the growth of cuttings. We should choose a tree with strong growth and high yield as the mother plant. Then cut off the top twigs that are strong, disease-free, pest-free and wound-free. Proper application of rooting agent and healing agent in the incision can promote wound healing and improve the rooting ability of cuttings. Each cuttings should be kept at about 13 centimeters. After preparing for the cuttings, insert them vertically into the nursery bed. After insertion, the temperature of the nursery bed should be controlled at about 26-27 degrees. However, it should be noted that the rooting rate of pistachio cuttage propagation is very slow, even if it is not properly managed.

3. Striping propagation

Striping propagation is the most commonly used method of propagation of human pistachio, which is carried out every spring, first of all, the sturdy branches that grow within two years are selected. Its diameter is controlled at about 2 cm, and then girdling is carried out at a position where the branch is about 22-24 cm from the top of the stem. The depth of girdling mainly depends on the size of the branches. When the xylem is peeled and white matter is found, clean it up. Then use duct tape to pack the wet clay, and try to use a container with good permeability to wrap the ring peeling part. if the permeability is strong, the rooting speed is fast. Tie both ends tightly to prevent it from spreading out and losing its effect. Under normal management, it will take root in 2-3 months.

The above is a brief introduction to the breeding methods of human pistachio, and the breeding method of human pistachio is also grafted, which is more troublesome to deal with. Therefore, we need to have certain technology, and when we breed, we should choose reasonable breeding methods according to technology and preparation, so as to ensure the success of reproduction. That's all for today's introduction. This article is for reference only. I hope it can help you all.
