What are the points for attention in planting sour horn?

Sour horn, also known as sour bean, sour fruit, is the fruit of a large evergreen tree growing in the tropics and subtropics. Sour horn is not common in our life, this is mainly due to the small scale of planting, long growth cycle, generally ten years of growth, ten years of flowering, ten years of fruit, is a very rare medicine. Well, today, the editor has brought you some points for attention in planting sour horn. If you are interested, oh, you can learn about it carefully.

1. Planting environment

Sour horn has higher requirements on the planting environment, and we need to decide according to its growth characteristics. Sour horn has the characteristics of cold resistance and light preference. The average temperature of the planting area should be kept between 18 and 25 degrees throughout the year, of which the average minimum temperature should not be lower than 10 degrees and the lowest temperature should not be lower than three degrees per month. The second is that the precipitation of the planting land is less, it is generally best to have intermittent drought and rainfall, and there can be no frost weather, which is suitable for growing in acidic loam.

2. Seed treatment

Before sowing, we have to treat the sour horn seed, because its seed shell is relatively hard, the absorption is very poor, and the budding rate is high. For sour horn seeds, we usually use warm water to soak the seeds, the temperature is about 40 or 50 degrees, and the soaking time is two days. In the process of soaking, we should constantly stir the seeds to make the seeds heated and absorbed evenly. Only in this way can the emergence speed and emergence rate of seeds be improved.

3. Scientific water and fertilizer

The growth of sour horn tree has little demand for water, so under normal circumstances, it does not need too much watering. During the period of young trees and its growth period, we mainly use nitrogen fertilizer to promote the growth of sour horns, about twice a year, and the amount of fertilizer is also increasing year by year. The adult sour horn tree needs a large amount of fertilizer, mainly in the flowering stage and fruit stage, so we need to apply fertilizer according to its growth characteristics, mainly urea in the flowering stage, combined with compound fertilizer, and calcium fertilizer in the fruiting stage. promote the growth of the fruit.

4. Pruning and overturning

When planting sour horn, we should also pay attention to tree pruning and dwarfing sour horn tree, which is convenient for later management and harvest. The pruning of sour horn tree is generally carried out from the young tree, at the beginning, the branch retains one or two main branches, and in the later stage, it slowly increases and the number of trunk, secondary and tertiary trunk, gradually expand the crown, and trim the crown. On the other hand, the fruit tree needs to remove dead branches, diseased branches, old branches, insect branches, dense branches and so on. In addition, after two years of planting, we have to dig holes and expand holes, which can not only improve the soil, but also promote the expansion of the root system, which is what we call basin mulching.

5. Weeding and disease prevention

Weeding is also critical in the planting of sour corns, especially in some areas where the soil is poor. In order to reduce nutrient consumption, we need to weed at least two or three times a year, especially in July and August. In addition, we should pay attention to the prevention and control of diseases and insect pests, the most important of which are powdery mildew, leaf spot, blue-green elephant and green beetle. We can use Baifanling wettable powder, methyl thiophanate wettable powder and omethoate emulsion for prevention and control respectively.

The above points sorted out by the editor are the most common problems when we plant sour horn, and they are also places that we need to pay special attention to in the process of planting.
