Planting techniques of Chaotian Pepper

Chaotianjiao is a very common kind of pepper in our life. Because it grows upward towards the sky, it is called Chaotianjiao. It is also called small pepper because of its small size. It is an indispensable important auxiliary material in our life. How do you grow and manage pepper?

Cultivation techniques of pepper

It is suitable for large seedlings to be planted, and the seedling age should be 60~70 days. In order to ensure strong seedlings, should take Yangqi or small bow shed seedlings. Spring pepper can start to grow seedlings in late February, and wheat pepper should grow seedlings in late March. Seedbed soil should be loose and fertile, which is the key to cultivating strong seedlings. If chemical fertilizer is applied, 0.2 kg of compound fertilizer, 5 g of boron and zinc fertilizer and 0.5 kg of plant ash are added to 15 cm thick seedbed soil per square meter. The seedbed soil is disinfected after preparation. The seedbed soil with a thickness of 15 cm per square meter is mixed with 20 g of 50% carbendazim WP or 20 g of 70% thiophanate-methyl WP, which can prevent and control blight and anthracnose.

In order to control underground pests, 15 cm thick seedbed soil per square meter mixed with 2.5% trichlorfon wettable powder 100 grams, can kill mole cricket, grubs and so on. Before sowing, the seeds are exposed to the sun for 2 to 3 days, then soaked in 10% potassium permanganate aqueous solution for 15 minutes, and then taken out and washed clean. After sowing, the seedbed should be warmed up, that is, the plastic film should be sealed tightly, the soil temperature should be increased, the temperature should be controlled at 20℃ during the day and 10℃ at night, and the seedlings can emerge in about 10 days. The seedlings should be fully cultivated. Spring pepper should be cultivated 20 square meters per mu, requiring 150 grams of seeds. Wheat stubble pepper should be cultivated 25 square meters per mu, requiring 250 grams of seeds. After the seedlings are unearthed, they should be ventilated and dehumidified in time to prevent the seedlings from flourishing. The temperature in the seedling shed should be controlled at 25℃~30℃ during the day and 15℃~20℃ at night. Due to the weak natural light in early spring, the light in the seedling shed is generally insufficient, so the film should be removed around noon on a sunny day to increase the light intensity and inhibit the excessive growth of seedlings. In addition, 15 days before transplanting, fertilizer and water should be controlled, air quantity should be increased, seedling training and squatting should be carried out to prevent tall seedlings and prosperous seedlings.

planting technique

Chaotianjiao likes wet and afraid of water. It is advisable to choose loam, sandy loam or clay loam with fertilizer and loose ventilation. The pH value of soil is 6.5~8. 3~5 cubic meters of fully decomposed high-quality farm manure can be applied per mu, or 50~80 kg of compound fertilizer of nitrogen, phosphorus and potassium (each containing 16%) can be appropriately increased or decreased according to the fertility of the land. In order to facilitate irrigation and drainage, high ridge cultivation should be adopted, with a ridge width of 0.6~1 m (planting 2~3 rows), a furrow width of 0.2 m between the ridges, and a vertical height of 0.2 m. In this way, drainage can be carried out in time when it rains heavily, and only irrigation in the furrow can be carried out in dry days, so as to keep the ridge surface loose and breathable, which is beneficial to the growth and development of seedlings. For ventilation and light transmission, the ridge should take the north-south direction. Before planting, irrigate the seedbed once with permeable water to promote the seedling to grow new roots, so as to facilitate the seedling. The seedlings should be planted and watered with the seedling water. In order to promote the early development and rapid growth of seedlings, quick-acting chemical fertilizer can be added to the seedling water. 4 kg urea and 2 kg potassium dihydrogen phosphate are dissolved in 1500 kg water per mu.

Growing time of pepper

Generally in mid-March or so, choose continuous sunny days without wind, sowing in the morning. In North China, spring direct seeding is generally sown before and after grain rain, and sunny and warm weather is selected for sowing. Row spacing is about 40 cm, sowing depth is 2 cm, sowing depth should be consistent, seeds should be evenly distributed, soil should be covered above the sowing ditch, and attention should be paid to moisture preservation.

Low toxicity biological pesticides for pest control

At present, people are beginning to pay attention to health, green organic food generally like, so that the price is high, fast sales. Therefore, the control of pepper diseases and insect pests should try to use low-toxicity biological pesticides to ensure the quality and safety of products. The disease can be selected Paenibacillus polymyxa, Caifengning, agricultural streptomycin, new phytomycin, Wuyixin and other antibiotic pesticides alternate control. Bacillus thuringiensis, nuclear polyhedrosis virus, abamectin, fruit and vegetable net, matrine and other biological pesticides and earthen plant ash, garlic juice, pepper water, etc. can be selected for pest control, prevention and early treatment should be adhered to, pests and diseases should be controlled in the initial stage, and damage and loss should be reduced.

As mentioned above, with more and more people eating spicy food, many special snacks and delicious dishes gradually emphasize taste, these are inseparable from the figure of the sky, so the market demand for spicy pepper is also increasing, planting pepper has also become a hot planting project, but also can not be planted blindly.
