Wheat is the most important crop of summer grain, and Shandong is an important wheat-producing province in China. After the snowfall, local agricultural experts were organized to go deep into the field to inspect the wheat seedlings to ensure the safety of winter wheat in winter.

Scientific guidance to ensure the safe wintering of winter wheat

Leling City is one of the important grain-producing counties and cities in Shandong, and the wheat planting area this year is stable at about 900,000 mu. The recent heavy snowfall and cold spell have caused the temperature to drop to around minus 20 degrees Celsius. After the snowfall, the Shandong Academy of Agricultural Sciences and local agricultural experts came to the fields in time to guide farmers to scientifically deal with possible wheat frost damage.

CCTV reporter Liu Cheng:This is the town of Kongzhen in Leling City, Shandong Province, and under the cover of snow, it is actually a large wheat field. Now the snow is almost as deep as my palm, like a thick "quilt" over wheat. This not only helps the wheat to survive the winter safely, but also provides a certain amount of moisture after the beginning of spring, allowing the wheat to thrive.

Li Shengdong, post scientist of the national wheat industry technology system:As the agricultural proverb goes, "Wheat seedlings are covered with snowflake quilts, and they sleep with steamed buns in the coming year." Because before this snowfall, the farmland had already shown signs of winter drought, and this snowfall replenished the moisture of the soil in time. Another thing is that this snowfall will play a very good role in delaying the occurrence of our pests, like the red spiders that appeared a few days ago, after this snowfall, it will delay their occurrence and will ensure our harvest next year.

Actively respond to the cold wave weather and do a good job in rape field management

At present, more than 9 million acres of rapeseed in Jiangxi have entered the seedling growth period, in order to cope with the adverse effects of cold wave and low temperature on the growth of rapeseed, Jiangxi Province sent hundreds of agricultural technician service teams to go deep into the field, guide farmers to spray nutrient solution and overwintering fertilizer to rapeseed, and solve the problem of rapeseed growth at low temperature.

In Tiehe Township, Xinjian District, Nanchang City, Jiangxi Province, Xiong Zhonghai, a large grain grower, seized the opportunity of the soil to be moist after the rain and organized farmers to apply overwintering fertilizer to rapeseed, so that the fertilizer could be directly dissolved in the soil, so that the rape could absorb faster, so as to promote the expansion of the taproot, the health of the seedlings, and ensure the safe wintering.

Xiong Zhonghai, a large grain grower in Tiehe Township, Xinjian District, Nanchang City, Jiangxi Province:The best way for rapeseed to safely overwinter is to cultivate strong seedlings and improve the resistance of rapeseed. Taking advantage of this rain, we sprinkled the overwintering fertilizer to allow the moist soil to quickly dissolve the fertilizer, so that the rape can better absorb nutrients from the soil and lay the foundation for a bumper harvest.

At present, 3.18 million acres of rapeseed in Jiangsu are in the pre-winter growth period, in order to cope with the cold wave weather, in the past few days, the Ministry of Agriculture and Rural Affairs organized a science and technology team to investigate the impact of the disaster in Yangzhou, and guide winter rape growers to do a good job in field management.

Wang Longjun, member of the Disaster Prevention and Mitigation Expert Steering Group of the Ministry of Agriculture and Rural Affairs and deputy director of Jiangsu Provincial Agricultural Technology Extension Station:For oilseed rape, its ability to tolerate low temperatures is relatively poor, so frost damage may have some effect. It is best to cultivate soil and roots, and if conditions permit, organic fertilizer can be applied to cover them to strengthen anti-freezing and seedling protection. For fields and weak seedlings with severe frost damage, some recovery fertilizer can be added to promote growth.

The facility greenhouse is turned on the "cold and warm" mode

Henan province's facilities greenhouse vegetable area of more than 4 million acres, in view of the continuous cold wave low temperature rain and snow weather process, local agricultural experts reminded that it is necessary to check the damage of the shed in time and clean the snow in the shed. For old sheds or greenhouses whose skeletons have been deformed, columns should be erected and reinforced, especially to prevent continuous snowfall at night, and the snow thickness on the shed can be quickly reduced by sprinkling snow melting agent and other methods to prevent the shed from collapsing.

Zhang Xiaowei, researcher at the Vegetable Research Institute of Henan Academy of Agricultural Sciences:All places that are susceptible to strong winds should be well reinforced, if there is light during the day, it is necessary to open the insulation quilt in time to see the light, and if possible, it is recommended to add a fill light to improve the photosynthetic efficiency. Increase the temperature in the shed to prevent freezing damage caused by vegetables.

In Xiajin County, Shandong Province, the recent heavy snowfall has brought the snow depth here to more than 20 centimeters. In order to alleviate the impact of heavy snowfall on facility agriculture, the local government immediately organized agricultural technicians to go deep into the towns and villages to guide agricultural production.

Yang Defeng, Director of the Vegetable Technology Station of the Agriculture and Rural Bureau of Xiajin County, Shandong Province:Do a good job of warming and insulation measures in the greenhouse, and hang double-layer or multi-layer film in the shed for heating. After the snowfall, the humidity in the shed is too high, which is very easy to cause diseases. In terms of prevention and control, powder and tobacco should be the mainstay, and carbendazim and chlorothalonil tobacco can be used for prevention and control.

In order to more effectively deal with the impact of low-temperature frost damage and rain and snow weather on facility agriculture, Lingbi County in Anhui Province has also given full play to the role of digital agriculture and used 5G Internet of Things technology to prevent low-temperature frost damage. In the fruit and vegetable greenhouses in Lingbi County, the newly used smart greenhouse digital agriculture planting monitoring technology has played a big role in the "cold and warmth" of fruits and vegetables.
