Temperature management, high-temperature and high-humidity environment, pay attention to not cover the grass as early as possible during the day, keep the grass at high temperatures at night, after the planting, after the seedlings are slowly growing, pay attention to the daytime temperature of 26-28 °C, and the temperature in the afternoon drops to 17- When the temperature is 18°C, the temperature will rise 2-3°C after the lid is covered. After the temperature is gradually reduced, the temperature should be about 15°C until the next day. After entering spring, the temperature will rise gradually. Pay attention to increase ventilation. Quantity, appropriate late grass cover, when the temperature is not less than 15 °C, at night can not cover grasshoppers, but pay attention to the cold weather. Take protective measures.
Light management, peppers grown in the greenhouse should ensure the temperature of the greenhouse, try to extend the time of light, as early as the late cover Ganoderma lucidum, so that more light plants, while maintaining the film surface clean, improve light transmittance. On cloudy days or in snowy days, the light intensity is low, and the plant respiration is expensive. The application of extra-root fertilizer and proper application of sugar water can improve plant immunity.
For fertilizer and water management, the first fruit (Mianjiao) is generally not watered before sitting. After the seedling stage, the cultivars are mainly cultivating, and the soil below the mulching film can maintain moist and good ventilation. When the seedlings are finished, they are poured with water. At this time, the pepper has grown to a diameter of about 3 cm. It can be applied with ammonium sulphate or potassium sulphate or sprayed with foliar fertilizer + photosynthetic nutrient film fertilizer to help plants absorb a lot of light and light energy. , light, compatible with conventional fertilizers, nutrients for plant growth and development to the limit.
Pruning adjustment, when the young fruit on the secondary branch of the main lateral branch grows to a diameter of 1 cm, leave 5 hearts in the upper part and pick up the heart, so that the nutrient is concentrated to supply fruit growth, and spraying on the prosperous plant. The promotion of Kaowang No. 3 is very prosperous, forcing the conversion of growth and nutrients into reproductive growth.
Pest control, timely emergence of pepper pests and diseases with targeted drugs + new high-fat membrane for effective prevention and control.
