Winter jujube is a major feature of winter. Its sweet and crispy characteristics make it easy for many people to put it down, and the effect and function of winter jujube is the real reason why everyone likes it. The effect and effect of winter jujube is very high, in addition to being able to supplement nutrition, but also to regulate some diseases. Winter jujube is not only delicious, crisp, fleshy, juicy, slag-free, sweet and fragrant, but also rich in nutrients. The jujube contains 20% to 36% sugar; it contains 19 kinds of human body such as aspartic acid, threonine and serine. The essential amino acid, the most characteristic of winter jujube is the high content of vitamin C. The vitamin C content per 100 g of pulp is as high as 380-600 mg (the vitamin c supplement can provide 60 mg of vitamin C), 70 times that of apple. Sixteen times as many as citrus, the mountain that was previously thought to be rich in vitamin C is also inferior. Winter jujube seedlings are highly adaptable, resistant to drought and sorghum, cold-tolerant (not less than -19-23 degrees in a week), high temperature resistance, regardless of mountains, plains, beaches, acid soils, saline-alkali beaches can be planted According to the topography and terrain, the community is divided according to local conditions. Generally, when the area of ​​the flat garden is 30-50 mu, and the mountain or hillland is built, the area of ​​the plot is 15-30 mu. The community should behave in a rectangular manner with an aspect ratio of 2:1 or 3:2, and the long side and the main wind direction should be as vertical as possible, and the planting line should be north-south. When planting, put the winter jujube seedlings into the pit, fill the soil, lift the saplings up, mention the upper root system that can see the winter jujube seedlings, fill in a layer of soil, step on the solid, and lift the seedlings upwards for the stretching of the roots of the saplings. Make the roots and the soil fully contact, improve the survival rate, remember not to plant the seedlings deep, the shallower the better, the planting is deep, the seedlings grow very slowly, must leak out of the graft. Winter jujube seedlings planted well enough water, wait a few days for the upper layer of soil to dry, cover the mulch, increase the ground temperature, prevent water evaporation, remember not to pour multiple times of water, the number of sap roots smashed, black, causing death; The tree stem uses a plastic sleeve to create a micro-environment for the seedlings, sprouting early, growing fast, and increasing the survival rate.
