The technical staff of the Chongming District Agricultural Technology Center recently went deep into the fields to guide growers to adopt a combination of physical and technical defense, and do a good job in greenhouse warmth measures to reduce the adverse impact of the cold wave on crops. The staff has stepped up to cover the greenhouse with two layers of film, and compacted it with soil at the edge of the film layer. In addition, they also purchased greenhouse heating blocks and equipped them with electric fuel heaters, once the temperature drops below 0, they will be heated by burning the heating blocks and turning on the electric fuel heaters.
Before the cold wave, the Agricultural Technology Center did extensive publicity work for growers, informing them to take anti-freezing and thermal insulation measures and strengthen the equipment of warming equipment. In the Shanghai Jiafujia Fruit and Vegetable Cooperative in Gangxi Town, the staff also replaced the new strong and windproof film to cope with the cold weather, and at the same time allocated warm fertilizer, and applied foliar fertilizer to the strawberries in the greenhouse through drip irrigation with water pumps, so as to increase the soil temperature and increase the cold resistance of the strawberries.
In addition, the trees in various parks and woodlands in Chongming have also put on "winter clothes" to enhance the cold and frost protection ability of the trees. In the process of responding to the cold wave, the agricultural department has issued relevant guidance and put forward a number of countermeasures, such as the old greenhouses, damaged film and other production facilities to be repaired and replaced in a timely manner, and the use of pull wires, temporary brackets and other reinforcement in advance, for open-field vegetables, if necessary, the temporary floating surface can be covered with white mulch, non-woven fabrics, shade nets, straw and other insulation.
For all types of fruit trees, the roots are the most difficult to resist the cold, especially young trees, which are more susceptible to frost damage. Therefore, it is necessary to spread soil at the junction of the aboveground part of the tree body and the underground part before freezing, and remove it when it thaws in the next year. In Qingpu District, the agriculture department has also taken a number of measures to ensure the safety and stability of vegetable production**.
Comments made by netizens on this: 1"The timely guidance of agricultural technicians and the emergency response of the agricultural department are really for the sake of crops, and I hope that the impact of this cold wave on crops can be minimized. ” 2."I was really touched to see the agricultural technicians working so hard to strengthen the greenhouse, and I hope that their hard work will pay off. ” 3."The agricultural work in winter is really not easy, and I hope that more attention and support can be given to **.
Through the response to this cold wave event, not only the protection of crops has been strengthened, but also the emergency response ability of agricultural technicians and the agricultural sector has been demonstrated, which has had a positive impact on agricultural production and stability. At the same time, it also reminds us to pay attention to weather changes at any time in agricultural production and take countermeasures to ensure the growth and development of crops.
