| 加固棚体，防风揭膜。检查和加固棚体，拉紧压膜线，修补棚膜破损处，晚上棚面再横向加拉两道铁丝或压膜线，防止大风揭膜。 Strengthen the shed body and remove the film against wind. Check and strengthen the shed, tighten the film pressing line, repair the damaged part of the shed film, and add two wires or film pressing lines horizontally on the shed surface at night to prevent the film from being exposed in strong wind. 2 Two 加盖帘被，注意保温。速将厚草帘或保温被启用重新加盖在棚面上，缩短通风时间，关闭通风口，注意保温。大拱棚内可加设“二膜”“三膜”，减少热量散失。 Cover the curtain and pay attention to heat preservation. Quickly put the thick straw curtain or heat preservation on the shed surface again, shorten the ventilation time, close the vent, and pay attention to heat preservation. "Two film" and "three film" can be added in the large arch shed to reduce heat loss. 3 Three 紧急应对，增温补光。迅速准备火炉、电炉，大棚加温块，电热器、热风机，补光灯等，临时增温补光，保障植株生长。 Emergency response, increase temperature and light. Prepare the furnace, electric furnace, greenhouse heating block, electric heater, hot air blower, fill light, etc. quickly, temporarily increase the temperature and fill light to ensure the growth of plants. 4 Four 科学管理，增强抗性。暂停浇水、施肥等农事操作盖土网 防寒布 麻绳 油麻绳 麻刀 沥青麻绳 静压造型线 自动浇注机 铸铁拍门 钢制拍门 玻璃钢拍门，烟雾剂防病，有条件的喷施“碧护”、“芸苔素”等提高植株抗逆性的药剂，增强植株抗性。 Scientific management to enhance resistance. Agricultural operations such as watering and fertilization shall be suspended, smoke agent shall be used for disease prevention, and agents such as "Bihu" and "brassinolide" shall be applied conditionally to improve the plant's resistance to stress, so as to enhance the plant's resistance. |
