Management Technology of Color Pepper in greenhouse in Autumn

Colored pepper is a light-loving and temperature-loving vegetable of Solanaceae. A big stubble of colored pepper in spring greenhouse grows vigorously in autumn, and it is easy for growers to relax their management. some flowers and fruits fall seriously in high temperature season, and some even produce dead seedlings.

At present, the price of colored pepper has entered a high level, so growers must strengthen conservation. High-yield demonstration technicians remind growers to do a good job in the following autumn management: appropriately reduce watering times and control the amount of drip irrigation each time. Colored peppers avoid pouring water after a long drought, flood irrigation often causes a large area of dead seedlings, so we must not irrigate or irrigate the seedlings. Increase the cost of high potassium fertilizer and calcium fertilizer, control nitrogen fertilizer, promote fruit spot color as soon as possible, and foliar fertilizer can be sprayed because of root senescence. Pay attention to the prevention and control of diseases and insect pests, increase the intensity of seedling protection, and properly apply growth regulators, but at the same time, we should timely get rid of the diseased leaves of the old leaves and increase the intensity of ventilation and light transmission between plants; when the temperature difference increases in the morning and evening, we should put down and close the vents in time, and wait for the temperature to rise and stabilize in ventilation and dehumidification, but we should give priority to heat preservation.
