How to Grow Peppers in a Greenhouse? A Detailed Explanation of Key Cultivation Techniques

Growing peppers in a greenhouse requires mastering the work of raising seedlings, sowing, seedbed management, soil preparation, transplanting, full-fruiting-stage management, pest and disease control, and harvest management.

Greenhouse Pepper Cultivation Techniques

I. Raising Seedlings

1. Seed treatment: Seedlings are generally raised from the Spring Equinox to Qingming. Expose the seeds to sunlight for 2 days to promote after-ripening, increase the germination rate, and kill pathogens carried on the seed surface.

2. Sowing for seedlings: After the seedbed is prepared, water it thoroughly, then scatter a thin layer of fine soil, spread the seeds evenly over the seedbed, cover with another layer of fine soil 0.5-1 cm thick, and finally cover with a small tunnel to retain moisture and increase temperature.

3. Seedbed management: After sowing, the daytime temperature should be 25-28 degrees, and the soil temperature around 20 degrees. Seedlings emerge in 6-7 days. If the seedlings grow leggy, spray 500 ml per kg of chlormequat, or 5 ml per kg of mepiquat chloride. If the seedlings are weak and yellow, spray Tianda 2116; before transplanting, use virus-killing agents such as Bingduqing or Zhibingling for root drenching along with foliar spraying, which has a good effect on preventing viruses.

II. Soil Preparation

Peppers have a long growth period and weak roots. To keep them flowering and fruiting continuously, good soil conditions and nutritional conditions are necessary. Before transplanting, plow the soil 10-15 cm deep. Apply 5000 kg of barnyard manure per mu, which can be mixed with 15 kg-20 kg of superphosphate, and make ditches for short irrigation and short drainage, with all ditches connected so that the field does not accumulate water after rain.

III. Transplanting

Transplant at the appropriate time to promote early rooting. Promoting early seedling growth is the main principle for determining the transplanting time and post-transplanting management.

IV. Management

Pepper seeds 13869615181 Peppers like warmth, water, and fertilizer, but high temperatures make them prone to disease, waterlogging easily kills the plants, and too much fertilizer easily burns the roots. Different stages of the entire growth period have different management requirements. After transplanting and before harvest, promote root growth and seedling growth; from the start of harvest to the full fruiting stage, promote seedling growth and focus on fruit development; after entering the high-temperature season, protect the roots and seedlings to prevent plant decline and death; in the late fruiting stage, continue to strengthen management to increase yield and income.
