Where does wild sour plum come from? What is the effect? How to plant it?

Wild sour plum, scientific name cherry plum, rose family, plum genus, perennial tree, its fruit is spherical, oval, color dividend, black, purple, yellow four kinds, bright beautiful, sweet and sour edible. So, where does wild sour plum come from? What's the effect? How to grow?

1. Where does wild sour plum come from?

Wild sour plum mainly produces Xinjiang Huocheng County Daxigou Township. Local people also call Tianshan small black plum, wild cherry plum and sour plum are unique to Asia and the only rare species distributed in the north slope of Tianshan Mountains in Daxigou, Huocheng County, Xinjiang. They are the only rare wild fruit species in the world and are also rare and endangered wild fruits in the world.

2. What is the effect of wild sour plum?

Wild sour plum fruit is rich in organic acid, natural pigment, pectin, va, vb, vc, ve, vpp and other vitamins and selenium, zinc, iron, calcium and other beneficial mineral elements for human body, rich in flavonoids tannin compounds, total nutritional amino acids, etc. Toxicological test results show that it has the attributes of appetizing summer heat, protecting liver and spleen, reducing blood fat, etc., and its nutritional value and processing suitability are much higher than those of various common fruits.

Its organic acid content is high, acid quality is positive; color bright stability, good thermal sensitivity; potassium, calcium content is high. Contains essential amino acids than the United Nations recommended health food crown blueberry fruit is 30% higher, which is unmatched by other fruit species. Calcium content in the highest fruit, for young children and the elderly calcium supplement is very beneficial.

Vitamin A content prominent and rich in amino acids, can increase appetite, help digestion role. It contains sufficient potassium salt, softens blood vessels, protects liver and spleen, inhibits hypertension and hyperlipidemia, and improves human immunity.

People with hyperactivity of liver fire should eat more. It can not only calm liver fire, but also help digestion of spleen and stomach and nourish liver. Wild plum contains a lot of citric acid, can effectively inhibit lactic acid, and expel harmful substances that make blood vessels aging. Because sour plum can promote the secretion of salivary glands and gastric glands, it can produce saliva and quench thirst, avoid carsickness when traveling, also help sober up, but also help muscles, muscles and vascular tissues to restore vitality, it has many benefits.

3. How to plant wild sour plum?

1. Building a garden

① The garden is selected from sandy loam with deep soil layer and unsuitable for ponding. The garden is built in the reverse temperate zone at an altitude of 800-1100 meters, and the protective forest belt is built around it.

(2) For seedling selection, I14-14, I16 - 56, II20 -38 were selected for grafting on stock, I16-38, V2-16 were selected for pollination.

2. Planting

In early spring, trenched plots are planted with 2 x 3-4 m or 3 x 4 m plant spacing.

3. Shaping and pruning

1. After planting, it starts to grow, and the height is 50-60 cm.

2 pruning winter pruning: time before germination (before the end of March), young trees winter pruning can be a little later. Pruning is mainly thinning, thinning out competitive branches and rotating branches, pruning trees to achieve sparse outside and dense inside, sparse at the top and dense at the bottom, maintaining a reasonable tree shape, so that the fruiting branch group can obtain sufficient light and nutrients, and delaying the rapid outward movement of fruiting parts as much as possible.

Growing season pruning: spring, summer and autumn. The pruning aims to regulate the contradiction between vegetative growth and reproductive growth, ease tree vigor and promote flower bud differentiation. Pruning methods include wiping buds, thinning branches, supporting branches, pulling branches, etc.

3. The pruning of young trees is mainly natural growth, and the backbone branches are cultivated to form natural spindle or slender spindle shapes. Generally, it is not necessary to cut short, thinning the rotating branches, thinning out the over-prosperous upper branches, drooping weak branches and competitive branches of extended branches at all levels, pruning as little as possible, directly bearing fruit branch groups on the trunk, arranged at intervals of 30-40 cm, and controlling the tree height at 2-3 meters.

(4) The pruning of fruiting trees is mainly sparse, sparse and combined, and appropriately truncated. Thinning competitive branches promotes rapid growth and formation of central leader stems.

(5) pruning of trees in full fruit period: retreat and rejuvenation of perennial branches in a planned way, thinning and strengthening of branch groups, removing old and leaving new ones, retracting and shearing to leave buds and branches.
