In order to ensure the safety of crops through the low temperature weather, Hangzhou Liangzhu Linhai Vegetable and Fruit Professional Cooperative prepared in advance and adopted multiple protection methods to "add clothes" to vegetables and fruits to keep warm.
Coming to the vegetable greenhouse of the cooperative, technician Xu Shiyun is explaining the precautions for planting cabbage in winter. This is one of the cooperative's greenhouses, about 2,000 square meters, which can be warm and moist as soon as you walk in, and the lettuce, cabbage, ice grass and other crops grown in it are also growing well. Xu Shiyun said that the greenhouse also has a two-layer insulation film, when the temperature is about zero degrees Celsius, the second layer of insulation film will be activated to resist low temperatures. If the temperature is lower, the heaters in the greenhouse will be turned on to heat up, and there are currently 12 heaters in the greenhouse, which is enough to survive the winter.
We've been keeping a close eye on the weather forecast, and while we're well prepared, we're also going to have to react quickly. Xu Shiyun said, "When the cold air hits, you must first close the tuyere of the greenhouse to prevent the cold air from coming in." At the same time, the inner insulation is turned on so that the internal temperature does not lose. When it reaches about minus 3 degrees Celsius, we turn on the heater. ”
Linhai Vegetable and Fruit Professional Cooperative is one of the important vegetable basket bases in our district, and has the largest greenhouse vegetable planting area in Hangzhou. At present, the cooperative has built standard smart greenhouses, hydroponic greenhouses, etc., and established the Linhai smart agriculture cloud platform, through which many projects can be operated. At the scene, Xu Shiyun demonstrated to reporters how to use the mobile phone to control the lifting of the second layer of thermal insulation film. With this intelligent means to protect the growth of vegetables and fruits, even in the event of sudden strong cooling, the greenhouse can also use the protective facilities as quickly as possible to ensure that the crops in the shed are warm for winter.
As a key vegetable basket base in Hangzhou, we have introduced various facilities and equipment in 2021, such as internal insulation, external insulation, hot air fans, etc., to empower the cultivation of vegetables and fruits with digitalization, improve their ability to cope with extreme weather, and carefully protect the residents' 'vegetable basket'. Xia Shiyu, a technician of Hangzhou Liangzhu Linhai Vegetable and Fruit Professional Cooperative, said.
