Cutting Propagation methods of Jujube

Jujube trees grow in mountains, hills or plains below 1700 meters above sea level. If you want to propagate jujube trees by cutting, what is the method of propagation?

I. cutting propagation methods of jujube

First moisten the sand bed, the wetting standard is that the hole does not collapse after drilling the sand bed. When cutting, while drilling holes in the sand bed with a small stick, the cuttings are dipped in pulp at the same time, and the diameter of the small hole is larger than that after dipping, so as to prevent the medicine solution from being squeezed out by the hole wall and reduce the medicinal properties. Cutting depth is about 3 cm, too deep can easily cause base rot, too shallow, cuttings dumping and root exposure after rooting, cuttings should be squeezed tightly after cutting, so that river sand and cuttings are closely combined.

II. Management of jujube cuttage seedbed

Use active intermittent spraying skills to control the seedbed temperature at about 26 ℃, no more than 30 ℃, and adhere to high humidity above 90%. Generally, the root primordium is formed after cutting for 10 days, and the root system can reach about 5 cm after 20 days. During the period of rooting management, 800 times chlorothalonil fungicide was sprayed on the seedling bed every 7 days or so to prevent the occurrence of rot.

Foliar topdressing should be carried out after rooting, spraying once every 3 to 5 days, such as 0.2% urea and potassium dihydrogen phosphate solution, or 10 mg / kg rooting powder solution to improve the rooting rate. The rooting seedlings cut in September should stay in bed to survive the winter, and through the addition of arch shed and other heat preservation methods to maintain the root system safety of wheat seedlings, not to suffer frost damage, and then transplanted to the nursery for continuous culture the following year.
