The continuous cold weather has a great influence on the growth of vegetables in the shed. I do not know what to do? Zhu Xiaohong, a technician of the Agricultural and Animal Husbandry Bureau of Chongxin County, recently received a call from Liu Shenghong, a grower in the greenhouse of Shuimo Village, Huanghua Township.
Zhu Xiaohong said: "The growth of vegetables during the period of this period generally does not cause frost damage. For continuous cold, low-temperature and low-light weather, the facilities will be exposed during the day, and the temperature of the greenhouse will be improved. In the evening, the straw will be put down and pressed tightly around it. According to temperature changes in the shed, appropriate amount of air is released to reduce the occurrence of diseases and insect pests, but the amount of ventilation should be small and the time must be kept short. When ventilating, pay attention to the direction of the vents, and do not allow the air to be directly blown into the shed to avoid injury or blows. Destroy the shed film.In the fertilizer and water management, generally do not water and fertilize, if it is rainy and snowy after watering, it is necessary to ventilate the moisture on the next day, and then apply fertilizer such as urea and ammonium sulfate. The previous day, a portion of the flowers and young fruit on the plant were removed, which was very effective in promoting the recovery of the crop.â€
Zhu Xiaohong added: "In the spring, wind power is high, and growers must constantly check whether the film is firmly attached."
