How many jin of chili peppers can be produced per mu
Chili peppers, as an important economic crop, their yield per mu directly affects the planting benefits. This article will analyze the components of chili pepper yield from the perspective of scientific planting and share verified high-yield management methods.
Core factors influencing the yield of chili peppers per mu
Relationship between variety selection and yield
Conventional varieties yield an average of 500 kilograms per mu, while high-quality hybrid varieties such as wire peppers and pointed peppers can exceed 4000 kilograms under scientific management. It is recommended to choose varieties that are resistant to diseases and have a high fruit-setting rate, as this is the fundamental guarantee for high yields.
Key points of sowing technology
Soaking seeds in warm water at 55℃ for 15 minutes can effectively kill germs, and a sowing depth of 1cm is optimal.注意事项: • Broadcast sowing requires 400-500 grams of seeds per mu • Maintain a row spacing of 40×50cm for point sowing • Build a small arch greenhouse after covering the soil to keep warm
Key parameters for environmental regulation
The seedling stage temperature should be kept stable between 25-30℃, and the day-night temperature difference should be controlled within 8℃. When the temperature is lower than 15℃, heating equipment needs to be started. Maintaining air humidity at 60-70% can effectively prevent diseases.
Five core steps for high-yield management
Precise water and fertilizer control
Apply high-phosphorus fertilizer during the bud formation stage to promote flowering, and increase potassium fertilizer during the fruit-setting stage. Use drip irrigation technology, controlling the water volume per mu each time to 15-20 cubic meters, and avoid large-scale irrigation that causes root rot.
Plant adjustment specifications
Remove the side branches below the main stem during the initial flowering stage and retain 4-6 main branches during the fruiting stage. Keep 8-10 effective fruiting branches per square meter to ensure ventilation and light.
Comprehensive prevention and control of pests and diseases
Use yellow boards to trap aphids, with a hanging density of 30-40 per mu. Alternately use mancozeb and pyraclostrobin during the high-incidence period of diseases, with an interval of 7-10 days.
Through the above systematic management, farmers can achieve step-by-step yield increases. It is recommended to establish a production log, recording data at each growth stage to provide a basis for continuous optimization. The application of modern facility agricultural technology can further increase the annual harvest batch to 5-6 times.
