CCTV News: Yesterday (December 17), the Ministry of Agriculture and Rural Affairs launched a Level IV emergency response to agricultural low-temperature rain, snow and freezing disasters in Beijing, Hebei, Shandong, Henan, Guangxi and other provinces, requiring all localities to pay close attention to weather changes, strengthen the investigation of potential safety hazards in agricultural facilities, and carefully organize winter agricultural production.
At present, all winter wheat has entered the overwintering period. What impact will the recent cold wave have on the safe wintering of winter wheat, and what countermeasures have been taken in the main producing areas? Let's take a look at the reporter's report.
Henan is the largest province in the mainland for winter wheat planting, and at present, more than 85 million mu of winter wheat has all entered the wintering period. In Zhoukou Xiangcheng, the main producing area, the city organized 16 agricultural technology expert groups to go deep into the fields of various towns and towns to guide farmers to scientifically do a good job in field management of low temperature weather to ensure the safe wintering of winter wheat.
Through on-the-spot inspection, experts believe that the rain and snow cooling weather has little impact on the first and second types of seedling wheat fields, which can increase the soil temperature and humidity of such wheat fields and ensure the safe wintering of winter wheat. At the same time, it can also kill some winter wheat insect pests and reduce the pressure for next year's pest control and control.
Han Jinghong, Director of the Plant Protection Station of Xiangcheng Agriculture and Rural Bureau, Henan Province: For the Wangchang wheat field and these three types of seedlings and weak seedlings, there is a possibility of frost damage. Next, for these three types of seedlings and prosperous wheat fields, foliar fertilizer should be sprayed in time to increase frost resistance.
In Wudi County, Binzhou, Shandong Province, more than 500,000 acres of winter wheat are covered by heavy snow, experts believe that this round of snowfall can replenish soil moisture, alleviate the possible drought of winter wheat, but also sink the soil, maintain soil temperature, and increase the stress resistance of wheat. At the same time, experts reminded that the cooling caused by the snowfall is a cliff-type cooling, which may have a certain impact on the wheat seedlings that grow vigorously before winter and the winter wheat varieties with poor frost resistance.
Liu Guoli, Agricultural Technology Extension Researcher, Agricultural Technology Extension Center, Wudi County, Shandong Province: After the snow melts and the temperature rises, we need to hoe and suppress the wheat field in time to increase temperature and moisture, promote weak seedlings to become stronger, enhance the tillering ability of wheat seedlings, and improve the basic number of wheat seedlings.
Strengthen the protection of facility agriculture and animal husbandry to reduce adverse impacts
The recent low temperature, rain, snow and freezing weather have also had a certain impact on the greenhouse vegetables and other facility agriculture and animal husbandry, and all localities have taken targeted measures to strengthen the protection of facility agriculture and animal husbandry to minimize the adverse impact.
In the past two days, more than 20,000 vegetable greenhouses in Feixiang District, Handan City, Hebei Province have all been covered by heavy snow, and nearly 1,000 vegetable greenhouses have been damaged to varying degrees. The local organization of agricultural technicians at all levels subcontracted to households, targeted guidance to vegetable farmers to clear the snow, strengthen the shed, reduce losses.
Huaxian County, Henan Province is an important vegetable production base, with a vegetable area of 148,000 mu in the county, covering spinach, celery, cucumber, pepper and other varieties. In Shigu Village, Chengguan Street, Huaxian County, more than 1,200 acres of celery here are in the growth stage, and agricultural technicians provide production guidance to growers from the aspects of cold protection and heat preservation, and increasing vegetable nutrition.
Gao Jun, Senior Agronomist of Huaxian Agricultural Technology Extension Center, Henan Province: Thermal insulation measures such as two membranes or multi-layer membranes should be added in the shed, and the light should be increased in the case of continuous cloudy days, heaters should be installed, and reasonable ventilation should be used to reduce humidity and prevent the occurrence of pests and diseases.
Since December 13, Inner Mongolia has ushered in a super cold wave weather process, which has brought great challenges to agricultural and animal husbandry production, especially animal husbandry. In Ordos, the local government issued the "Technical Guidance on Animal Husbandry to Cope with Cold Wave and Blizzard Weather" to help farmers and herdsmen cope with extreme weather. Up to now, more than 11.6 million yuan of disaster prevention subsidies have also been disbursed.
Qiao Yuan, first secretary of Ulanjilin Village, Etuoke Banner, Ordos City, Inner Mongolia: In response to the cold wave and snowfall, it is very important to coordinate the reserve of sufficient forage, which can increase the ability of livestock and poultry to withstand the cold. At the same time, the snow should be cleared in time to reduce the load-bearing capacity of the shed, and straw curtains or plastic film should be added to the livestock and poultry shed to improve the temperature of the shed.
