Colonization can be carried out when the depth of 10 cm is not lower than 15 °C(wholesale greenhouse pots). Ditching at a line spacing of 60 cm, applying ripe organic fertilizer. From the north-south ridge of 20 cm high and 70 cm wide, a 20 cm deep watering ditch is opened in the middle, the distance between the two ridges is 30 cm, and the ridge surface is slightly inclined to the south(propagation tray). The mulch is covered with mulch film, and the planting hole is set according to the row distance of 40 cm and the plant spacing of 20-30 cm.
Use a punch to punch holes in the mulched mulch at a distance of 30 to 35 cm (or use a blade to make a cross-shaped opening and then dig a hole), and plant 2 plants per hole(flat plastic tray). If planted in winter and spring, the temperature will be lower when planting, and the seedling water will be poured after 7 days(plug trays). The daily temperature in winter should be kept at around 25 °C, not below 18 °C, the night temperature is around 16 °C, and not below 12 °C.(greenhouse soil block propagation trays)
Or spray 1 kg of 5% chlorothalonil dust per 667 square meters, spray once every 7 days, and spray 2 to 3 times(seed starter trays). It is planted on sunny days in the morning, and the depth of the nursery is 2 cm below the surface of the nursery. When the temperature is low, the higher ground temperature should be controlled, and the low temperature can be adjusted by watering in the morning(gallon plant pot). The dust method and the smoke method should be preferred, and spray treatment can be used in dry and sunny weather.
Maintain at 25 ~ 30 ° C, no more than 30 ° C can not let the wind; 12 ~ 18 when the appropriate air release(plastic grow pots), so that the temperature is reduced, maintained at 20 ~ 23 ° C; 18 ~ 0 when the appropriate temperature is 18 ~ 20 ° C; 0 ~ 6 ° temperature At around 15 °C. Attention should be paid to the relationship between temperature and ground temperature, and a certain temperature difference between day and night is required(gallon nursery pots). When the temperature is high, the lower ground temperature should be controlled.(greenhouse soil block propagation trays)
When the humidity in the greenhouse is too high(square nursery pots), the leaves of the pepper will be wetted, and it is easy to cause disease without dehumidification. Selecting under-film irrigation in the morning can effectively reduce the humidity and promote the evaporation of surface water. The humidity in the greenhouse rises for about 1 hour, and the air is quickly released for 10 minutes(black plastic plant pots). The air outlet can be larger, but the time should not be too long, repeating 2 to 3 times.
Capsicum blight: In the early stage of the disease(greenhouse supplies pots), 45% chlorothalonil aerosol 110-180 g fumigation is used every 667 square meters, and smoked once every 7 days, depending on the condition, 3 to 4 times. 3,200 to 3,700 points are planted per 667 square meters, and 6400 to 7400 plants are planted. After the central disease strain is found in the middle and late stages(2 gallon nursery pots bulk), the roots are filled with 50% methyl ketone WP 800 times solution or 72.2% guaiac water agent 600-800 times solution, 100-200 ml per hole.
(greenhouse soil block propagation trays)Anthrax: Fenigation with 110% to 180 grams of 45% chlorothalonil aerosol per 667 square meters, 1 time for 7 days(cell trays). In the early stage of the disease, use 50% mixed sulfur suspension agent 500 times solution, or 80% anthrax fumei wettable powder 600-800 times solution, or 68.75% oxacillin manganese zinc water dispersion granule 800-1200 times solution, or 1:1 : 200 times Bordeaux mixture, or 75% chlorothalonil WP 600 times liquid spray(1 gallon nursery pots bulk), spray once every 7 to 10 days, even spray 2 to 3 times.
