The planting time and method of Chaotian pepper should be sown in the middle of March, and active fertilization is needed to ensure the yield.

Time: around the middle of March every year, when there is no wind on a sunny day, sow seeds in the morning, and it is appropriate to sow seeds before and after Grain Rain in North China. Methods: to select loose sandy loam or clay loam, the ph value should be between 6.5and 8, and 3-5 cubic meters of farm manure should be applied per mu. In order to facilitate drainage and irrigation, high border cultivation should be adopted. The seedling bed should be watered once before planting to promote the growth of new roots. Quick-acting chemical fertilizer can be applied in the later stage, and water should be watered every other week after each harvest.

Chaotian pepper is a kind of variety that likes temperature and cannot bear stagnant water. In recent years, the demand for Chaotian pepper in the market is getting higher and higher, and the annual consumption of Chaotian pepper is increasing, so many people want to try to grow it. So the first step is to start from the planting technology and time.

Planting time and method of Chaotian Pepper

Time: generally around the middle of March every year, choose a continuous sunny day without wind and sow seeds in the morning. In North China, it is generally chosen to sow before and after the direct broadcast in spring, that is, Grain Rain, and to sow in sunny and warm weather. The row spacing is about 40cm, the sowing depth is about 2cm, the sowing depth should be consistent, the seed should be uniform, cover the soil above the sowing ditch, and pay attention to preserving soil moisture.

Methods:

Chaotian pepper likes to be wet and afraid of water, so try to choose fat-preserving, loose and aerated loam, sandy loam or clay loam. The ph value of soil is between 6.5 and 8. Generally, about 3-5 cubic meters of fully mature high-quality farm fertilizer can be applied per mu, or about 50-80 kg of compound fertilizer of nitrogen, phosphorus and potassium (16% each), which can be increased or decreased appropriately according to the fertility of the land.

In the later stage, in order to facilitate drainage and irrigation, high border cultivation should be adopted, with a width of 0.6-1m (generally about 223 rows), a width of 0.2m between the border and a vertical height of 0.2m, so that it can be drained in time when the rain is heavy, and only irrigated in the ditch during drought. It can keep the border surface loose and ventilated, which is beneficial to the growth and development of seedlings. In order to be ventilated and transparent, the border should be in the north-south direction.

The seedling bed was watered once before planting in order to promote the emergence of new roots and be beneficial to seedling emergence in the later stage. The seedlings should be raised, planted and irrigated. In order to promote the early development and rapid growth of seedlings, appropriate quick-acting chemical fertilizers can be added to the seedling water, using about 8 jin of urea and 4 jin of potassium dihydrogen phosphate per mu, dissolving into 1500 kg of water.

Fertilization Technology of Chaotian Pepper

The main results are as follows: 1. In the middle and later growth stage of Chaotian pepper, the plant has many fruits and needs a large amount of fertilizer. The plots with good soil fertility and sufficient bottom fertilizer can be irrigated with 10kg water soluble fertilizer (N ∶ P ∶ K = 2 ∶ 1 ∶ 2) or urea 10kg plus potassium sulfate 7.5kg, and the plots with no organic fertilizer, insufficient topdressing and premature senescence can be irrigated with 10kg water soluble fertilizer (N ∶ P ∶ K = 2 ∶ 1 ∶ 2) or urea 10kg plus potassium sulfate 7.5kg for 2-3 times in a row.

2. During the full fruit period and after each harvest, 0.3% potassium dihydrogen phosphate solution or 1% superphosphate leaching solution or 1-2% potassium nitrate solution was sprayed once every 7-10 days for a total of 2-3 times, which could increase the weight of single fruit, make the fruit bright and bright, and improve the grade of Chaotian pepper.

Irrigation technique of Chaotian Pepper

To harvest fresh pepper field, after each harvest, according to soil moisture appropriate watering, generally every 7-10 days watering, in order to harvest dry pepper-based plot appropriate water control, generally stop watering 15-20 days before harvest, Chaotian pepper is not resistant to drought, more afraid of waterlogging, such as Rain Water less, watering should be a small number of times, if there is stagnant water should be eliminated in time, otherwise it will cause the death of fallen leaves.

Pest Control of Chaotian Pepper

1. Anthrax

Symptoms: generally easy to occur in high temperature and rainy season, mainly harmful to fruits, emerging water-immersed yellowish brown spots, brown edges, central grayish brown, with raised concentric patterns, often integrated by many small spots, sometimes black and sometimes orange-red, when wet, the surface of the disease spot overflows red sticky matter, the internal tissue of the damaged fruit is semi-soft rot, easy to dry shrink, the pathogenic part is membranous, and some rupture. If it is not actively controlled, the yield and quality will be seriously affected.

Prevention and control methods: generally select disease-resistant varieties, reasonable close planting, crop rotation and other agricultural measures, but also use chemical control: that is, at the initial stage of the disease, spray 70% Aimu water dispersible granules or 70% pure Jiatuo wettable powder, in areas with high resistance to severe disease, it is recommended to use 3000 times suspension, once every 7-10 days, 2-3 times continuously.

2. Virus disease

Symptoms: Chaotian pepper virus disease is one of the more serious diseases in Hebei, Henan and other areas in recent years, the main symptoms are chlorosis, necrosis, deformity and so on, resulting in a large number of falling flowers and fruits, seriously affecting the yield and quality of pepper in the later stage.

Prevention and control methods:

1. It is necessary to cut off the route of transmission in order to thoroughly control tea yellow mites, aphids and other pests.

2. In the hot and dry season, it is necessary to water in time to create favorable conditions for the healthy growth of hot pepper.

3. Chemical control: 7.5% poisonous Aoshui 1000 times or 50% Guangmei wettable powder 1000-1500 times or 0.5% Shenhaisu 600,800 times can be sprayed every 8-10 days or continuously for 3-4 times.

Generally, Chaotian pepper will be planted in the early spring of each year, when the weather gradually warms up, and the survival rate of planting will also increase, which is the best time of the year. After planting, proper fertilization and irrigation are needed to ensure its adequate nutrition. In the later stage, it is necessary to increase the amount of fertilizer, and pest control should also be done well, so that the yield of Chaotian pepper will be high.
