Detailed Explanation of Key Cultivation Techniques for Korean Dried Chili Peppers

China is one of the countries that consume the most chili peppers, and it is also a major exporter of dried chili peppers. Dried chili peppers are one of the important agricultural and sideline products for foreign trade export. China has dedicated chili pepper production bases in both the south and the north. Korean dried chili pepper varieties are favored by merchants and numerous bases for their excellent quality, diverse uses, and high yield! For this reason, our company specifically provides cultivation techniques for high-quality Korean dried chili pepper varieties.

1 Cultivation Season

Chili peppers, aside from not being suitable for continuous cropping with Solanaceae crops, have no strict requirements for preceding or following crops. Chili pepper cultivation mostly involves winter-spring sowing, with harvest completed by late summer or early winter.

In northern regions, sowing and seedling raising are mostly done in protected areas in spring, and transplanting to open fields occurs after the last frost between April and May.

In the middle and lower reaches of the Yangtze River, sowing and seedling raising are done under simple protected conditions from November to December, with transplanting in March to April.

In southern China, sowing and seedling raising are done under plastic film covering from December to January, with transplanting in February to March.

2 Seedling Raising

In cultivation, chili peppers can be divided into two methods: direct seeding and seedling transplanting, but seedling transplanting is mostly used in production. Chili pepper seedling raising includes open-field seedling raising and protected seedling raising. Before sowing, seeds are soaked and germinated, and thinning is done in a timely manner to cultivate strong seedlings and enable early transplanting. This allows for greater yield before the high-temperature and drought period in July to August. Open-field seedlings have a seedling age of about 60d, and the transplanting period is delayed, flowering and fruiting are late, and per-unit yield is relatively low. Therefore, most regions adopt protected seedling raising. Protected seedling raising includes heated hotbed seedling raising with fermenting materials and cold bed seedling raising with film covering. Generally, greenhouses and hotbeds are used for sowing, and the sowing hotbed should maintain a bed temperature above 20°C. The optimal seedling age is when 8 to 10 true leaves have unfolded, about 60d.

3 Transplanting Density

To increase chili pepper yield, the main approach is to increase the number of plants per mu and the number of fruits per plant. As for single fruit weight, there is little difference. Therefore, appropriate close planting is one of the important measures for increasing yield. However, when using Korean pepper varieties, the plants are tall, have extremely high fruit-setting ability, and have a large spread, making them suitable for sparse planting, with every 667
