At present, the pepper seedlings have already entered the preparation stage. Strengthening the seedbed management of peppers and nurturing strong seedlings are very important for the high quality and high yield of peppers.
In the nursery period should focus on the following technical aspects:
1, choose a good seed. Select high-yield, stable production, disease resistance, and high-quality varieties.
2, fine seedbed. Choose oysters, grow 10 meters in width and 1.2 meters in width, make deep plowing, drying, ripening the soil, and apply rotting 200 kg of manure, 1.5 kg of compound fertilizer to ensure nutrient supply, pest control, and carbendazim 0.1 kg. .
3, control the bed temperature. The temperature of the bed during the day before the true leaves are controlled at 15-20°C and 5-10°C at night. When the true leaves are exposed, they are controlled at 20-25°C during the day and 10-15°C at night.
4, strengthen the lighting. In order to make the seedbed more sunlight, cover the cover as early as possible to extend the light time. When removing the film, it is necessary to prevent cold air from directly blowing into the seedbed and cause seedling damage.
5, adjust the humidity. The humidity can be adjusted by watering and ventilation. The bed soil has high humidity and can be ventilated, humidified, and damped with wood ash. Bed soil moisture is low and can be properly watered. The amount of watering is controlled in a water bath, before 9 o'clock in the morning and after 5 o'clock in the afternoon.
6, cultivating seedlings. Spreading seedbeds, 2-3 true leaf seedlings, 5-6 true leaf seedlings, generally 2-3 seedlings. When 5-6 true leaves are selected, the seedlings are harvested at a seedling distance of 2-3 PCT; the draw seedling seedling bed is plucked with 3-4 true leaves and leaves 2-3 strains of healthy seedlings.
7, timely hardening seedlings. When the leaves of hot pepper seedlings reached 10, the seedlings began to be cultivated. During the day, the membranes were removed and ventilated at the two ends of the rice dumplings. Afterwards, the amount of ventilation was gradually increased so that the temperature of the hardening seedlings gradually decreased. In the 2 weeks before planting, when the leaves of the pepper seedlings reached 13-14 leaves, they were all uncovered during the day and frost-proof at night, and the film was still covered. During the week before planting, the membranes should be lifted every day and night for hardening seedlings to adapt the seedlings to the exposed environment.
