Chili peppers are a common type of side ingredient that can add flavor to ordinary dishes, especially in southern China, where many regions cannot do without spice. So, what are the techniques for growing chili peppers in the South?
1. Site selection and land preparation
Choose land with good drainage and convenient irrigation and drainage, plow deeply, and make raised beds. The bed width is generally 1.3-1.7 m (including ditches), with 2-3 rows planted. While making the beds, apply 50-80 loads of decomposed farmyard manure, 15 kg of superphosphate, and 25 kg of plant ash per mu as base fertilizer.
2. Sowing and raising seedlings
Before sowing, water the seedbed soil thoroughly and break it up finely and level it. The seedbed width is generally 1.5-1.7 m. Early-maturing varieties are generally sown in January, while late-maturing varieties are generally sown in February to March. Planting one mu requires 75-120 g of seed. After sowing, cover the seeds with fine soil mixed with old chaff ash or coal ash, about 2 cm thick, just enough to cover the seeds.
3. Transplanting
For transplanting chili peppers, a soil temperature above 15°C is suitable. For early-maturing varieties, the row spacing is 40-50 cm and the plant spacing is 26-33 cm, with 1-2 plants per hole; for late-maturing varieties, the row spacing is 66-73 cm and the plant spacing is 50-60 cm, with 1 plant per hole. Choose a sunny afternoon for transplanting.
4. Field management
After transplanting and survival, carry out one shallow intertillage in time. After transplanting, seize sunny days to apply seedling-promoting fertilizer, and each application should not be too much or too concentrated. After the first and second layers of fruit set, apply more fertilizer. During the growth period, pay attention to watering and always keep the soil moist.
5. Pest and disease control
