On December 20th, in order to resist the cold wave, Liu Liangbin, the person in charge of urban soilless cultivation in Ruian City, was busy arranging various cold protection measures in his three tomato greenhouses, including the installation of diesel heaters and other means to minimize the impact of cooling weather on greenhouse tomatoes.
It is understood that the tomato can tolerate a minimum of about 5 low temperatures, but when the temperature is lower than 15, the growth is slow, it is easy to form deformed flowers and fallen flowers and fruits, when the temperature drops to 10, the plant stops growing, and the low temperature below 5 for a long time will cause frost damage. At present, Liu Liangbin has prepared 7 diesel heaters for his three greenhouses, and directs the hot air to the rows of tomato plants through the air film pipe to ensure that the temperature in the greenhouse is kept above 5 under the cold wave. At the same time, Liu Liangbin also carefully inspected the greenhouse and closed the greenhouse tightly to ensure that there were no cracks and prevent cold air from entering the shed.
Since December 15, after the city issued a yellow warning for cold waves, agricultural departments around the city have taken active action and have sent 58 technical service guidance groups, with a total of 191 people and 271 service subjects. Each team went to the field to check the hidden dangers, check the seedling situation, promote management, and guide farmers to deal with cold weather scientifically. The technical service guidance group guides farmers to implement various cold and frost prevention measures according to time and place, harvest fruits and vegetables and other agricultural products in a timely manner, and do a good job in cold and frost prevention work such as spring crops such as rape and wheat and cash crops such as fruits, tea, vegetables, and Chinese medicinal materials, so as to ensure the safety and orderliness of agricultural production.
