Premature cultivation technique of greenhouse green pepper

1. Seedling 1 soaking and germination: soaking in warm water of 55°C (water is 3 times of seeds) for 15 hours, draining with a damp cloth, placing in light-free germination at 28°C, 50% whitening can be broadcasted. 2 Seeding: In the late January of each month, 4 centimeters thick cover seedlings will be planted out of each pot, and the base fertilizer will be used to make the water leveling. Sown (10 g seeds per square meter) and cover the soil 1 cm. After the emergence of the seedlings, cover soil 1 cm to protect the roots. 3 Lianmiao: 10 days before planting, more than 50% of seedlings sprouted, the daytime temperature was controlled at about 27°C, and nighttime was controlled at about 13°C.

2, colonization 1 fertilization: Mushi farmyard fertilizer 5000 kg, compound fertilizer 50 kg. 2 sheds: 15 days before planting. 3 ridges and rafts mixed planting: ridge width 90 cm, ridge height 15 cm, narrow ridge planted a row, wide ridge planted two rows, the density of 7000-8000 per mu. 4 watering shed: pouring planting water, sealing shed film temperature insulation. 5 Cooling and dehumidification: After a week, the water will be irrigated, and the air will be released to cool off. 6 Cultivated seedlings: After 3 days, cultivating loose soil and seedlings. The temperature in the shed was controlled at 27°C, and the night temperature was 15-20°C. 7 top-dressing watering: more fruiting watering fruit, fruit more fertilizer period. 8 Anti-lofting of cover soil: After flowering, set up seedlings to prevent seedlings.

3, field management 1 temperature control: 25 ~ 35 °C seedling period; the main fruit set daily temperature 25 ~ 30 °C, night temperature 15 ~ 20 °C; results of the period 25 ~ 30 °C. 2 Controlling humidity: The seedling period is not ventilated. The relative humidity of the main fruit setting period is 70 to 80, and the result period is 50 to 60. 3 Uncovering: When the outside temperature reaches 30°C, remove the greenhouse film. 4 Rows of rafts: Control the watering during the rainy season and drain them in time.
