Pepper cultivation technology

Today I will tell you about the cultivation technology of peppers, please take a look

Seedling cultivation

1. Seed treatment: Seedlings are usually raised from the spring equinox to Qingming. Expose the seeds to the sun for 2 days to promote ripening, increase germination rate, and kill germs on the surface of the seeds. Alternatively, soak them in 0.5% trisodium phosphate, or 300-400 times potassium permanganate, or 1% thiourea for 20-30 minutes to kill germs on the seeds. After repeatedly washing the solution on the seeds, soak them in warm water at 25-30 degrees for 8-12 hours.

2. Seedling raising and sowing: After the seedbed is ready, fill it with water, and then spray it with 3000 times of Green Heng No. 1 for disinfection. Then sprinkle a thin layer of fine soil, sprinkle the seeds evenly on the seedbed, and then cover it with a layer of 0.5-1 cm thick fine soil, and finally cover it with a small shed to keep moisture and increase temperature.

3. Seedbed management: After sowing, the daytime temperature is 25-28 degrees, and the ground temperature is about 20 degrees. Seedlings will emerge in 6-7 days. After 70% of the seedlings have arched the soil, sprinkle 0.5 cm thick fine soil on the seedbed when there is no water on the leaves. This is to fill the gaps and retain moisture to prevent the roots of the seedlings from being exposed. The seedbed must have sufficient water supply, but the soil cannot be too wet. When the height of the pepper reaches 5 cm, the seedbed must be ventilated and hardened. The ventilation holes should be flexibly controlled according to the growth of the seedlings and the weather temperature. The seedlings can be hardened outdoors 10 days before transplanting. Hardening the seedlings should be carried out gradually and must not be done in one step. If the seedlings are too long, you can spray 500 ml per kilogram of dwarfing agent, or 5 ml per kilogram of mepiquat. If the seedlings are weakly yellow, you can spray Tianda 2116. Before transplanting, use virus spirit or plant disease spirit to irrigate the roots and spray the leaves, which is very effective in preventing viruses.
