In the next few days, affected by the cold air, my country’s central and eastern regions will usher in a large-scale round of strong rain, snow, and strong winds. The middle and lower reaches of the Yangtze River and most of the north, northern China, and central and southern parts of Northeast China will have a cooling rate of 4 ～10℃. With such a wide range of temperature drops, are your greenhouses ready for production? The overwintering tomato planting and pepper planting make many vegetable farmers busy. However, the weather is not beautiful, and the sudden attack of cold air brings pressure to the vegetable farmers in the north. The cold prevention of crops has become their main job. Li Shengyin, a consultant expert from the Yangling Association for Science and Technology and a researcher at Northwest A&F University, put forward several suggestions for vegetable farmers. First of all, pay attention to night heat preservation, and keep the night temperature in the greenhouse above 12 ℃ as much as possible. Secondly, pay attention to light and ventilate during the day, and close the air vents in the afternoon to prevent excessive temperature loss in the shed. Once again, plow the ground deeply, water the soil moisture, and raise the ground soil temperature. Finally, the greenhouse is covered with a film in time to reinforce the facilities so that it can be covered with thermal insulation quilts later. Li Shengyin said: “The weather turns cold, in addition to physical attention to temperature changes, but also to enhance the resistance of the crops, increase the application of farm manure and organic fertilizer, to ensure soil permeability and disease resistance. This season is still tomatoes and peppers. During the high-incidence period of gray mold and blight, always pay attention to whether the crops are diseased. When a disease is found on individual plants, the corresponding drugs should be sprayed in time. However, “empty shots†should not be used. To economically and effectively prevent diseases."
