Cultivation Techniques and Management Methods for Korean Pepper

I. Seedling Raising

1. Seed Treatment Soak Korean pepper seeds in warm water at 55°C for 12h, remove them, then dress the seeds with 50% Tuzet wettable powder, mix evenly, and set aside for later use.

2. Seedbed Preparation Drive some supports in the middle of the greenhouse, place the seedling trays filled with seedling soil on the supports, and prepare for sowing. In mid-March, sow the dressed Korean pepper seeds evenly in the seedling trays, water thoroughly, and cover with topsoil.

3. Pricking Out After the seedlings emerge completely, strengthen temperature and water management to cultivate strong seedlings. From April 10 to 15, the Korean pepper seedlings should be pricked out into the greenhouse, with a pricking-out density of 5cm x 5cm, and transplanting is prepared once the weather improves.

II. Transplanting

1. Land Preparation and Fertilization Select a plot with high, dry terrain, good drainage, and fertile soil. Prepare the land in autumn and form ridges in spring. Before ridging, apply 1t of farmyard manure per 667 sq m, with a ridge spacing of 80cm.

2. Transplanting Around May 15, set the pricked-out Korean pepper seedlings into 80cm-wide ridges, with double rows planted on the ridge, a row spacing of 25cm, a plant spacing of 30cm, and a seedling retention number of 555 plants per 667 sq m.

3. Film Mulching After transplanting, cover with film promptly to preserve heat and moisture.

III. Field Management

1. Cultivation and Weeding After removing the agricultural film in early July, carry out manual weeding promptly, achieving two hoeings and two passes, and remove large weeds once in the later stage.

2. Foliar Fertilization Spray foliar fertilizer once each in the early flowering stage and full flowering stage of Korean pepper, using 0.25kg of potassium dihydrogen phosphate per 667 sq m plus 0.5kg of urea each time.

3. Pest and Disease Control The common disease of Korean pepper is pepper blight. Pepper blight is a bacterial disease. If not controlled in time, it can spread across the whole field in a short period and is a devastating disease for Korean pepper. Control method: spray DTM fungicide or agricultural streptomycin in the early stage of disease onset, which can effectively prevent the occurrence and spread of the disease. The common insect pests of Korean pepper are underground pests at the seedling stage, such as white grubs and mole crickets. Use phorate or carbofuran mixed with soil or poisoned bait to trap and kill them, and the control effect can reach 100%.

IV. Harvest

From the end of September to early October, after the Korean peppers are fully mature, pull up the whole plants and place them in the field to dry in the shade, then pick the Korean peppers and prepare them for sale.
