Production of black jujube leaf tea
Black jujube leaf tea is rich in vitamin C, amino acids, flavonoids and other ingredients that are beneficial to the human body. The specific production technology is as follows: first, leaf picking and treatment: leaf picking time should be carried out from July to October, picking fresh leaves free of diseases and insect pests. After harvesting, the leaves should be hung in an indoor ventilated place to facilitate the formation of amino acids in the leaves. After an hour of drying, the leaves should be transversely cut into fragments of the same specifications. Second, kill the green: the aim is to use high temperature to destroy the enzyme activity of fresh leaves and prevent vitamin C and other forms in the leaves.

Selection of almond nursery
The selection of nursery land is the key to the success or failure of raising seedlings. Improper selection of nursery land will not only affect the yield and quality of seedlings, but also waste all previous efforts. The almond nursery should choose neutral loam and sandy loam with flat topography, fertile soil, deep soil layer, groundwater level below 1.5 meters, good irrigation and drainage conditions and loose soil. The soil is too sticky and easy to consolidate, which affects the growth and development of seedlings and seedlings. Do not continue cropping in the nursery, which will lead to diseases and affect the survival rate, growth and development of seedlings. Where drupe seedlings have been cultivated

There are sowing, drilling and dibbling, and dibbling is more. First open the hole 2-3 cm deep, row spacing 50×30 cm, sow 4-5 seeds per hole, seed coat hard water permeability is poor, it is advisable to soak for 24 hours before sowing, generally it takes more than 20 days to emerge, when the seedlings have 4-5 true leaves, they can be picked up

Harvest of jujube fruit
The suitable harvest time is determined according to different varieties, edible purposes and processing methods. The harvest of different varieties: Jin jujube, Xiangzao jujube, pear jujube and winter jujube, which are mainly eaten raw, are mostly harvested in the brittle ripe period. The fruit of this period has bright color, high sugar content, sweet and sour, crisp, tender and juicy, and good flavor, which can fully show the characteristics of fresh food varieties. If the harvest is too early, the skin color is green, the flesh is hard, the juice is less, and the palatability is poor; if the harvest is too late, the pulp loses water and becomes soft, the pericarp thickens and loses fresh flavor. Dried varieties, such as gray jujube, Jixin jujube, golden jujube, etc.

Cultivation points of Japanese Pear and Korean Pear
Select suitable rootstocks to cultivate virus-free strong seedlings: the suitable rootstocks are sand pear, Yunnan pear and Chuanli pear, and Chuanli pear and Yunnan pear should be used in southwest China. In the construction of the garden, virus-free seedlings should be planted as far as possible, and suitable pollination trees should be arranged. Reasonable close planting to increase per unit yield: the trees of Japanese and Korean pears are relatively shorter than Chinese pears, the branches are shorter, the crown is more compact, the planting density should be reduced appropriately, and the yield per unit area should be increased by increasing the number of plants per unit area. The plant row distance depends on the tree shape, garden topography and soil fat and thin. That is, Xiaoguan Shu
