The weather outside the shed is cold, and the shed is full of greenery. On February 6, walking into the vegetable greenhouse of Hebei Bohua Agricultural Science and Technology Co., Ltd., located in Gaocheng District, Shijiazhuang City, the reporter saw that the tomato seedlings here were growing well, and the tomatoes were hanging on the vines, and they were fresh and tender.
In view of the current low temperature weather, we must pay attention to regulating the temperature and humidity in the greenhouse, make up the light in time, and try not to water or water less ...... in the shed”
In the greenhouse, Su Jianhui, an agronomist from the Agriculture and Rural Bureau of Gaocheng District, Shijiazhuang City, carefully checked the growth of tomatoes, and was conducting "on-site teaching" to guide workers to manage scientifically and master the technical essentials of tomato management and protection at low temperatures.
What degree Celsius temperature is better? When is it more appropriate to water? How to prevent pests and diseases after snow? At the scene, "student" Gao Junmin listened very carefully. In response to her questions, Su Jianhui patiently answered.
Scientifically regulate the temperature in the shed, and in case of extreme low temperature, you can use heating blocks, electric heaters, electric stoves and other methods for emergency heating", "strictly control watering, reduce the humidity in the shed, and it is easy to produce diseases when the humidity is high", "avoid bacterial ......infection caused by wounds caused by fruit and vegetable pruning, thinning flowers and fruits, etc."Face-to-face communication and hand-in-hand guidance, Su Jianhui supported "warm moves" on the spot and carefully explained the management measures in the tomato field.
Experts can see the problem accurately, and the solution to the problem is even better. After listening to the expert's explanation on the spot, Gao Junmin gave a thumbs up and said that she had mastered the knowledge and technology of greenhouse management, knew how to prescribe the right medicine, and was more confident in growing good vegetables.
Gaocheng District is a demonstration county for the development of vegetable industry in Hebei Province, and in 2023, the vegetable sowing area in the district will be 1390,000 acres, with an output of 6370,000 tons, 1300 million plants. In recent years, Gaocheng District has gradually formed a global industrial pattern dominated by greenhouse tomatoes and greenhouse cucumbers, and the common development of open-field vegetables, plastic onion and garlic, facility fine vegetables, greenhouse melon vegetables and other bases.
In order to cope with the adverse effects that low temperature, rain, snow and freezing weather may have on vegetable production, in the past few days, the Gaocheng District Agriculture and Rural Bureau has refined and improved the prevention plan and technical plan, organized agricultural technology experts to go deep into the production line, and guided growers to scientifically carry out vegetable management and protection under low temperature conditions, and scientifically prevent and respond to low temperature weather by reinforcing greenhouses, strictly controlling temperature and humidity, and ensuring the safe growth of vegetables in greenhouses.
Near noon, Su Jianhui walked one shed after another, and he instructed everyone from time to time, "Now that the temperature is low, while doing a good job of heat preservation, we should also spray some foliar fertilizer to enhance the stress resistance of the plant, so that the tomatoes planted are both high-quality and high-yield."
