CCTV*** National Spring Ploughing and Spring Management has been launched from south to north. What is the impact of the ongoing cold wave, rain, snow and freezing weather on agricultural production and agricultural products, and how to deal with it? We followed the lens of the CCTV reporter of the main station and went to Henan, Shandong and Hunan, the main grain-producing areas, to see how all places coped.
He Yugang is the captain of the Zhongnong Lihua Henan Spring Ploughing Service Team, as a professional socialized service team, He Yugang and the team provide technical guidance to local farmers during the spring ploughing. After receiving the message for help, they immediately set off and rushed to Bianjia Village, Zhongmu County.
The one waiting in the field is Hu Shichao, a local farmer. In 2023, with the help of He Yugang's team, he will expand the planting area by more than 30 acres and plant high-quality varieties, but in the face of two consecutive large-scale snowfalls since the beginning of the year, especially this cold wave and freezing weather, he has no bottom in his heart.
The service team measured the snow thickness of the wheat field on the spot, and the deepest part of the snow was 15 cm, reaching the level of heavy snow or even blizzard. From the analysis of the current growth of wheat seedlings, the frost damage of the snowfall at the end of January in the early stage is not large, and it has a slight impact, and the degree of frost damage of this snowfall will continue to be observed. However, judging from the current temperature, it is much lower than the average temperature of the same period in previous years, so the service team suggested that farmers should increase patrols and take remedial measures in time in the days after the snow.
At present, the cold wave in Henan is coming to an end, but when the snow melts, it will absorb a lot of heat from the soil, and when the temperature in the ground drops, it will freeze some of the overwintering pests, and at the same time, the snow will also turn into water when it melts, replenishing water to the wheat roots.
Shandong: The greenhouse of scientific response facilities is "well protected from the cold".
The current cooling has no obvious adverse effect on the safe wintering of winter wheat, so how to deal with the rain, snow and freezing weather, how to scientifically manage the facilities and greenhouses in the northern region? Let's take a look at the reporter's visit in Shandong.
Lingcheng District, Dezhou City, Shandong Province is a national vegetable standardization production base, and the vegetable sowing area is stable at about 140,000 mu all year round, of which the facility vegetable sowing area is nearly 100,000 mu.
This is an agricultural demonstration industrial park located in Yidukou Town, Lingcheng District, with a total of 76 standardized greenhouses in the park. When the reporter came to the park, the growers were clearing the snow from the shed. The reporter found that although the snow on the ground did not pass the surface of the feet, there was not a lot of snow in the shed.
The snow was accompanied by strong winds, and the outside temperature dropped to minus seven or eight degrees, but when the reporter walked into the shed, there was a feeling of warmth like spring. The temperature on the monitor in the shed is 2211 degrees Celsius, more suitable for crop growth. The tomatoes were planted in October last year and have grown to a man's height and will be picked in a few days.
The expert also reminded farmers that in the management, special attention should be paid to the gradual unveiling of the quilt after the cloudy day is clear, and it must not be uncovered to prevent the plant from "drooping".
Unlike traditional solar greenhouses, the vegetable cultivation here is almost unaffected by the current rain and snow in this smart glass greenhouse, which is 20 kilometers away.
Staff Wei Chao told reporters that the environmental temperature and humidity, soil moisture, carbon dioxide and other sensing nodes distributed in the greenhouse can collect environmental information in the shed in real time, and transmit it to the computer terminal through the wireless communication network, which can grasp the growth environment of crops in real time.
Hunan: The intelligent trading system is guaranteed to regulate the "vegetable basket".
At present, the cold wave front has moved south into the sea, but the cold and freezing weather in Hunan Province continues. What is the situation of the local "vegetable basket" supply? Let's take a look at Hunan Province again.
Located in Changsha County, Hunan Province, Haijixing International Agricultural Products Logistics Park is the largest vegetable hub in the central and southern regions, where vegetables from more than 20 provinces are gathered, and more than 10,000 tons of vegetables are sent to Guangdong, Guangxi and other provinces and regions every day, ensuring the supply of vegetables for residents within 600 kilometers around. Although the temperature has dropped significantly in the past few days, there is still an endless stream of vehicles entering and exiting the logistics park.
The reporter learned that the entire park monitors the daily vegetable intake, sales and sales through the intelligent trading system, and through real-time comparison and analysis of data, timely deployment to ensure the adequacy and stability of the entire market. From the information on the origin of vegetables, the reporter saw that vegetables came from Guangdong, Yunnan, Fujian, Zhejiang and other places. At present, the delivery of vegetables is unimpeded.
This fully automated intelligent three-dimensional cold storage has a storage capacity of more than 30,000 tons, and through data monitoring, important information such as the weight, quality, origin, time, and storage location of vegetables can be dynamically grasped in real time.
At present, Haijixing International Agricultural Products Logistics Park also strengthens the liaison with the vegetable production base, does a good job in the connection of the vegetable production base in the province and surrounding provinces and cities, grasps the supply channels and markets, and signs the base of the emergency supply guarantee agreement to ensure that the goods in Changsha Haijixing Market are guaranteed in bad weather.
