Chaotian pepper high-yielding cultivation techniques

Seed treatment: 2-3 days before seedling breeding, in order to increase the germination rate and germination potential. Then put the Seeds into warm water of 55°C, and keep stirring. When the water temperature drops to 30°C, stop stirring, add water to soak for 7-10 hours, remove the mucus, and drain the water for sowing. Sowing and raising seedlings: Usually in the middle and late March, Yangshuo grows seedlings or exposes seedlings in open fields to extend harvest time and increase yield. Pre-planting seedbeds poured enough water, sowing rate of 6-8 grams per square meter, after sowing cover soil 2 cm, then sprinkle poison bait to prevent underground pests, and finally in bed soil cover film heating and moisturizing. After the seedlings are removed, the mulch film is removed and the seedling age is transplanted for 45-60 days. Soil preparation and fertilization: The cultivation of sandy land with high topography and energy irrigation can be selected. Combine land preparation with 5,000 kg of high-quality mixed fertilizer per acre and 30 kg of superphosphate. Soil compound fertilizer is replaced with ternary compound fertilizer. Colonization: Usually transplanted in the middle to late April to early May, and wheat pods were transplanted after harvesting. Transplanting spacing 40-50 cm, spacing 20-30 cm, planting two plants per hole. Management: When the plants are planted, they should be irrigated with water, especially after the wheat is harvested. The temperature should be high and should be irrigated with water. Slow seedlings to flowering fruiting period appropriate water control, in order to increase the temperature, promote root development, prevent leggy. Increase the amount of water after flowering. In the full fruit period, topdressing urea once every two months. Each application of 10-15 kilograms per acre, promote high yield and prevent premature aging. Spraying 0.3% potassium dihydrogen phosphate two times in the middle and late stages of growth to prevent disease and increase production. During the growth period, the roots were plucked several times to protect against soiling and lodging. Red and bright peppers can be harvested at once, or they can be picked once. Pest control: Diseases are mainly viral diseases and anthrax. Viral diseases are transmitted by locusts, and locusts are regularly controlled from the seedling stage. In the early stage of virus disease, potassium permanganate, naphthalene acetic acid, phytophthora disease, virus A or lobular enemy spray was used for prevention and treatment. Anthracnose is controlled by 50% thiophanate-methyl, chlorothalonil, or diethylphosphorus aluminum. The main insect pests are Helicoverpa armigera and Heliothis erythraea, and they are controlled with phoxim or pyrethroids to ensure that there are no insect eyes on red peppers.
