First, focus on seedling management in the nursery. The key during winter is to carefully control temperature and humidity within the seedling shed. After sowing, until the "Winter Solstice" (around late December), the seedlings are in a critical growth phase, and it's important to keep the shed open for ventilation to avoid excessive moisture. From the "Winter Solstice" to "Early Spring" (until early February), when temperatures are low, the main concern is insulation. However, proper ventilation should still be maintained to prevent diseases. Once spring arrives and before planting, gradually increase air circulation based on actual conditions.
Pest and disease control is also essential during this stage. Common issues include damping-off, blight, gray mold, aphids, and snails. Timely application of appropriate pesticides can help prevent these problems. Healthy pepper seedlings should have full foliage, no damage or pests, thick stems, short internodes, thick leaves, short petioles, dark green color, strong roots, and active buds ready for transplanting.
Second, use protective facilities to ensure timely planting. Pepper is a warm-season crop, and its growth depends heavily on temperature. Considering Kaixian’s climate and available protective structures, the ideal planting periods vary: greenhouse or plastic film-covered greenhouses allow early planting in the second half of February; small arch sheds are suitable for late February to early March; and mulch film is best used around mid-March.
Third, select suitable land for planting. Choose fields with no soil-borne diseases, good drainage, and deep, well-draining loam or sandy loam soil. Avoid areas where peppers or similar crops were previously grown. In winter, plow the soil deeply and prepare it before planting. For early maturing varieties, slightly denser planting is acceptable. A typical planting density is 1.1–1.2 meters between rows (including surface ditches), with 0.5 meters (or 0.3–0.4 meters) between plants, resulting in approximately 3,000 plants per mu.
Fourth, apply base fertilizer and manage topdressing properly. Based on pepper’s nutrient needs, apply a balanced mix of nitrogen, phosphorus, and potassium. Apply a one-time base fertilizer by mixing over 2,500 catties of compost per mu, 40–50 catties of superphosphate, and 6–8 catties of potassium chloride. During the flowering stage, apply diluted manure water. Later, apply concentrated fertilizer 1–2 times, adding 3–4 catties of potassium fertilizer per mu. Additionally, foliar sprays of 0.2%–0.3% potassium dihydrogen phosphate can be applied 2–3 times to support healthy flower development and fruit set.
Fifth, strengthen field management and ensure timely harvesting. When using greenhouses or small sheds for early spring cultivation, be cautious of high temperature and humidity, which can cause heat stress and damage to seedlings. On sunny days, make sure to ventilate regularly. Secure the soil around the base of the plants and monitor for pests and diseases. To achieve higher early yields, harvest the first 1–2 sets of fruits when they reach a certain size but are not fully inflated, typically around 20 days after flowering. As the season progresses, wait until the fruits are fully mature before picking, and harvest every 5–7 days to maximize total yield.
Vitamin Series
Vitamin C is necessary for the formation of antibody and collagen, tissue repair (including some redox effects), metabolism of phenylalanine, tyrosine and folic acid, utilization of iron and carbohydrate, synthesis of fat and protein, maintenance of immune function, hydroxylation of 5-hydroxytryptamine, maintenance of vascular integrity, promotion of non heme iron absorption, etc. at the same time, vitamin C also has Antioxidant function, Anti free radicals, inhibit the formation of tyrosinase, so as to achieve whitening, light spot effect. In human body, vitamin C is a highly effective antioxidant, which is used to reduce the oxidative stress of ascorbate peroxidase (ascorbate peroxidase) Sch. There are also many important biosynthesis processes that require vitamin C participation.
