The Central Meteorological Observatory predicts that due to the impact of the cold wave, there will be strong winds and cooling weather in central and eastern my country, and sandstorms in some areas in the north. The Central Meteorological Observatory issued a warning for cold waves, strong winds, sandstorms and strong convective weather on the 27th. At present, more than 35 million mu of food have been sown in spring nationwide. The wheat in Shaanxi and Shanxi has entered the festive period, and the Northeast region has also entered a busy season for preparation for farming.

The geometry of this cold wave weather on spring plowing and spring management

Let's take a look

Strong convective weather is coming

Many places have launched emergency plans

Starting from the 26th, Jiangxi ushered in strong cooling and strong convective weather. The Jiangxi Provincial Meteorological Bureau launched a level 4 emergency response to major meteorological disasters (strong winds). Many places quickly launched emergency plans to guide farmers to take relevant prevention and response measures.

At present, more than 9 million acres of rapeseed in Jiangxi have entered a critical stage of pod formation. Before the arrival of strong convective weather, many places have organized agricultural technicians to go deep into the fields to guide farmers to respond well. In Taihe County, Ji'an City, agricultural technicians were divided into 23 groups to rush to each village to manage the rapeseed field.

Deputy Director of Taihe County Agricultural Technology Promotion Center Peng Zhongliang: Once water accumulates, the rapeseed roots are prone to hypoxia and rot, so clearing and draining ditches should be done in time. In addition, spray some germlin in advance to prevent the spread of the disease.

Last night, strong convective weather such as thunder, strong wind, heavy rain and hail occurred in Wuning County, Jiujiang City, and some houses and crop greenhouses in Qingjiang Township were seriously damaged.

The reporter learned from the Jiangxi Provincial Meteorological Department that this round of heavy cooling and strong convective weather process will last until the 28th. During this period, the weather changes violently, strong winds and hail are at high risk of disasters. The minimum temperature in the province will drop to 7~9℃, and strong winds of level 8 to 10 will occur in some areas. Relevant departments should strengthen inspections and pay attention to prevention.

Beware of late spring cold

Reduce the impact of disasters on agriculture

The current time is when spring plowing is prepared in various places, with significant temperature rise and cooling alternately occurring. What is the impact on spring plowing and spring management? Let’s see the expert analysis.

In February this year, the national average temperature was minus 2.3℃, which was 0.3℃ lower than the same period last year. Since March, especially last week, temperatures have increased significantly in most parts of my country's Middle and Northeast China. Experts said that early spring from February to March is a season of alternating cold and warm weather, and the weather is hot and fluctuating temperatures are the norm, and it has little impact on agricultural production.

It is expected that in the next week, due to the cold wave, there will be a significant cooling in the central and eastern regions. Due to the significantly high temperature in the early stage, the cooling will have little impact on winter wheat and rapeseed in most areas.

·Wheat in central Shaanxi and southern Shanxi has a risk of mild to moderate frost during the jointing period;

·Rapan in southern Shaanxi, northern Chongqing, northeastern Yunnan, and northwestern Hubei has a risk of mild frost damage.

Researcher at the Institute of Agricultural Environment and Sustainable Development, Chinese Academy of Agricultural Sciences: In the future, in April, we must also pay attention to whether the temperature will further drop and cause some situations of late spring cold, implement disaster prevention and reduction measures, and reduce the impact of disasters on agriculture.
