Spring greenhouse pepper colonization management
Early spring greenhouse peppers are generally planted from mid-February to early March, and then poured into the bottom water. After water infiltration, the holes are sealed and the mulching membrane is sealed. At this time, the following three management tasks should be performed: Timely temperature-controlled ventilation Planting outside the greenhouse temperature is still low, pay attention to insulation, daytime temperature is maintained at 22 ~ 30 °C, kept at 12 ~ 22 °C at night is appropriate, if the cold can be in the shed plus a small arch shed insulation, with As the weather gets warmer, it gradually increases ventilation. When the minimum temperature outside the shed is above 15°C, it must be fully ventilated. During the day, the seams should be pulled open, the seams must be uncovered, and the middle seams should be ventilated at night. Reasonable watering Fertilization Planting should be done with enough water, as early as possible, watering as little as possible, if you need to water, should be selected before the sunny afternoon film pouring dark water. After the peppers begin to expand, they should be poured into a film under dry weather. After that, the soil should be kept moist to prevent the soil from drying out. In the high-temperature season during the later period of fertility, it can be used to pour water sooner or later to regulate soil and air humidity. When the pepper grows to about 3 cm, 25,000 kg of organic fertilizer can be applied per hm2 of cultivator, and 700 kg of vegetation can be used. After pepper is sitting, 200 kg of urea can be applied per hectare of water; “Simudou†pepper sits After that, 15,000 kilograms of composted manure was applied per hectare, and then 200 kg of compound fertilizer could be applied once every 20 days. Pay attention to the fact that flowering and fruit-protecting peppers are important factors affecting yield. In order to effectively prevent flowering and fruit drop, in addition to strengthening field management, hormone treatments are also applied to increase fruit setting rate. The green peppers have grown in size about 20 days after flowering, but the skin is thin and light and should not be harvested. Usually about 35 days after flowering, the flesh hardens, the peels harden, and the skin color is green when harvesting is the best. Heavy, resistant to extrusion, easy storage and transportation.
