The latest course of planting techniques and methods of sour horn

Sour bean is a large evergreen tree of the genus Leguminosae, which is mainly produced in southwest China. Potassium acid is used by many chefs to enhance the flavor of dishes. And sour horn contains polysaccharides, which has a good luminous effect, which can protect human skin and reduce ultraviolet radiation. The market in our country is also getting bigger and bigger, so how to grow sour horn? The following editor brings you the planting method of sour horn, let's have a look!

1. Sowing seeds at the right time

When the fruit of the sour horn tree is ripe, choose the fruit and plant it, wash the seed clean and remove the pulp from the seed. The general sowing time is around the Beginning of Spring every year, but the seeds of sour horn are relatively hard, so soak in warm water for about 2 days before sowing, and then choose your own planting method to sow. After sowing, the seedlings can sprout in about a week after normal management, and all the seedlings can be completed in almost three weeks. The growth rate of the seedlings is relatively fast. After about one month, the seedlings can grow to 18 cm, and the roots extend to about 12 cm. If you want to raise seedlings and afforestation, you should make a good land and then dig a good sowing hole in the rainy season, control the sowing density, and pay attention to not grazing in this area.

3. Fertilization management

In the seedling stage and new shoot growth, more nitrogen fertilizer should be applied, mainly in a small amount to promote the growth of sour horn. The times of topdressing should not be less than twice a year, and the times of topdressing should be increased appropriately with the extension of planting time. Urea is the main fertilizer for topdressing, and we need to control the amount of fertilizer according to the age of the tree. For example, in the flowering and fruiting period of adult trees, when the nutritional demand is the greatest, it is necessary to increase the amount of fertilizer application and improve the rate of flowering and fruiting. Then, according to the growth habits of sour horn, compound fertilizer and calcium fertilizer were applied properly to promote fruit expansion.

3. Shaping and pruning

Sour horn tree is a large tree, which is difficult to manage in the later stage, so we should have a proper crown of dwarf sour horn tree when we plant it. From the young tree stage to do a good job of pruning, planting within 1-2 years, cut off the lower branches, dense long branches and thin branches, and retain 1-2 main branches. The nutrition demand of sour horn is large, and the yield is high. Therefore, when the trunk grows to about 80 cm, it is necessary to retain about 4 first-class main branches, and then gradually reduce to promote the growth of branches at all levels and expand the crown. The adult trees should be pruned after harvest, that is, before the new shoots grow in spring, and the overlong, dense, overlapping and crossed branches should be cut off. Improve the permeability of fruit trees, ensure the normal growth of trees, and cultivate strong fruiting mother branches.

4. Cover the tree disk

After planting sour horn for about 2 years, it is necessary to expand holes and dig holes to guide the expansion direction of the roots. It is especially important for the areas where the planting land is barren, and it is also an important measure to improve soil structure and enhance soil fertility. Weeding should be carried out at least twice a year, when weeds grow rapidly from July to August and from October to November. The weeds removed can cover the soil, reduce soil water and fertilizer loss, increase soil temperature, prevent drought, promote the growth of sour horn and increase yield.

The above is a brief introduction of the sour horn planting technology, the shaping and pruning of the sour horn is more important, we should control the growth of the tree, enhance the growth performance of the branches, ensure that the sour horn forms a dwarf crown, and facilitate the later growth and management of harvest. That's all for today's introduction. This article is for reference only. Thank you for your reading and support.
