Technical Guidelines for Non-polluted Early-maturing and High-yield Cultivation of Pepper

To ensure successful pepper cultivation, it is essential to focus on proper seedling management. During the winter, maintaining optimal temperature and humidity in the nursery is crucial. After sowing, especially before the winter solstice (late December), the seedlings should be exposed to open air to avoid excessive moisture and promote strong growth. From the winter solstice to early spring (around February), the temperature drops, so the nursery should be insulated but still allow for controlled ventilation. Once spring arrives, gradually increase air circulation to acclimate the seedlings to outdoor conditions. Additionally, regular pest control is necessary to prevent diseases like damping-off, blight, and powdery mildew, as well as pests such as aphids and snails. Healthy pepper seedlings should have full foliage, no damage, no pests, thick stems, short internodes, thick leaves, short petioles, dark green color, and strong roots. When planting, it's important to use appropriate protective facilities based on local climate conditions. Pepper is a warm-season crop, so early planting can be done using greenhouses or plastic film tunnels, ideally in late February. For smaller arch sheds, planting should occur in late February or early March, while mulched fields are best planted around mid-March. Selecting the right land is also key. The soil should be free from disease, deep, well-drained, and warm. Loamy or sandy loam soils are ideal, and previous crops should not be the same species. Before planting, the soil should be deeply tilled. For early maturing varieties, a slightly denser planting arrangement is acceptable, with spacing of 1.1–1.2 meters between rows and 0.5 meters between plants, resulting in about 3,000 plants per acre. Fertilization is another critical factor. A base fertilizer application should include more than 2,500 pounds of compost per acre, 40–50 pounds of superphosphate, and 6–8 pounds of potassium chloride. Top-dressing should begin at the early flowering stage with diluted manure water, followed by two more applications of concentrated fertilizer, with potassium added at 3–4 pounds per acre. Foliar sprays of 0.2%–0.3% potassium dihydrogen phosphate can be applied 2–3 times to support flower development and fruit set. Field management is equally important. In early spring, greenhouses or small sheds should be used, and care must be taken to avoid high temperature and humidity stress, which can harm young plants. On sunny days, proper ventilation is necessary. Soil should be compacted around the base of plants, and regular monitoring for pests and diseases is required. To maximize early yield, harvest the first 1–2 sets of fruits when they reach a reasonable size, even if not fully inflated. Later, wait until the fruits are fully developed, harvesting every 5–7 days to achieve higher total production.
