Key points of cultivation techniques of Sanying Pepper

First, sowing and raising seedlings

1. Sowing seeds

The seeds can be sown from early March to mid-April. Pour the seedbed thoroughly before sowing, sow seeds after infiltration, and cover soil with 1cm. A small arch shed was used to cover the seeds after sowing. It is generally not ventilated before emergence, and the temperature of the seedling bed is kept at 25 ℃ and 30 min. Ventilation began after emergence, and the film was removed in late April. If the seedbed is dry, it can be properly watered and fertilized according to the growth of the seedling.

2. Apply sufficient base fertilizer

Proper close planting

General per mu application of rotten soil fertilizer 3 000-4000kg, diammonium phosphate 20kg, and then the whole field. High border size row cultivation, border width 70-80cm, small furrow width 30cm, large furrow width 40cm, border ditch depth 10cm. Two rows were planted in each row, the distance between plants was 20-25cm, and there were two plants in each hole. When the seedlings grow to 8 true leaves, they can be planted, and the planting density is generally 8000mu 10000 trees per mu.

II. Field management

1. Ploughing and weeding

Timely ploughing, weeding and soil cultivation to promote root growth and prevent lodging.

2. Pick the heart

When the plant grows to 14 leaves and buds appear at the top, it is necessary to pick the heart in time to promote the growth of lateral branches and increase the yield.

3. Topdressing and watering

After slowing down the seedlings, the plants entered the peak growth stage, and urea 15-20kg was applied per mu. After coring, compound fertilizer 15-20kg per mu was applied to promote effective branching and ridge sealing of plants as soon as possible. When the plant entered the early flowering stage, compound fertilizer 20-25kg per mu was applied to increase the fruit setting rate and create nutritional conditions for fruit expansion. When the fruit is watered with topdressing, the fruit should be watered less or not during the ripening period.

4. Pest control

The main diseases harmful to pepper are anthracnose, scab, blight, virus and so on, and the main pests are aphids, tobacco insects and so on.

III. Timely harvest

Three eagle peppers are generally harvested in the middle and late October, which are usually harvested by pulling seedlings. After pulling seedlings, they are laid flat in the field to dry for 4 days, bundled and transported to a free place, dried and dried for 20 days according to the sequence, and then sold by stages.
