High temperature in the north!Southern rainstorm!Influence on the production of "Sanxia"?

At present, the work of summer harvest and summer species is nearing the end. The Central Meteorological Observatory predicts that in the next week, the main rain belt will be in the north, and there will still be high temperature weather in Huanghuai and other places in North China.

How does this affect agricultural production?

What is the overall meteorological conditions during the "San Xia" production period?

Li Sen, a senior engineer of the National Meteorological Center, interpreted this.

Preliminary situation

High temperatures of rainfall are entangled in the north and south

Not conducive to agricultural production

Recently, the Central Meteorological Observatory issued high temperature and rainstorm early warning. Since June 15, Henan, Shandong, northern Anhui, central Jiangsu, Shanxi, southern Shanxi, southern Hebei, southern Shaanxi and other places have appeared in large -scale high temperature weather. Inner Mongolia, Xinjiang, Gansu, Ningxia, Shandong, Shanxi, Jiangsu and other places have 26 national meteorological stations, the highest temperature of the day breaks through the historical value of the local June, and Henan's high temperature is particularly prominent. On the 16th, the highest temperature of 59 national meteorological stations in Henan Province reached or exceeded 40 ° C, of ​​which 11 stations exceeded 41 ° C.

The continuous high temperature and rain caused the soil bias in North China, Huanghuai and other northern summer broadcast areas. The drought in Henan and other places has continued or developed, which has a certain adverse effect on the timely sowing and seedling growth of summer corn and summer soybeans.

Since June, many rounds of heavy rainfall have appeared in many places in the south. In some areas, extreme heavy rainfalls that exceed the historical extreme value have brought adverse effects on agricultural production.

Continue to strengthen the weather in the water, which is not conducive to the growth and development of rice, corn, cotton, open field vegetables, and economic forests. The process of early rice fertility is delayed; A suitable temperature and high humidity environment is conducive to the occurrence of pests and pests.

Future prediction

Meteorological conditions during summer harvest are generally better

According to the scheduling of the Ministry of Agriculture and Rural Affairs, as of June 21, the large -scale wheat collection of the main producing area of ​​the Xialiang main production area has basically ended, and the wheat harvest has been a foregone conclusion; nearly 90 % of the summer species in the country (excluding double -season late rice) The progress is slightly slower year -on -year.

Li Sen introduced that during the summer harvest, there were so clear weather in the wheat harvest area, and there was no large -scale continuous precipitation process. It was very beneficial to the maturity of wheat. The progress of wheat was fast and the quality was high. However, during the summer species, the rain was late, and the sentiment was poor, and the seedlings were not conducive to the timely summer of the summer.

In order to do a good job of "San Xia" meteorological services, the Central Meteorological Observatory releases a special report of summer and summer meteorological services every Tuesday and Friday to send out the objective product one by one. Remote sensing monitoring winter wheat mature harvesting information to improve the degree of refinement of services; the meteorological departments in various places have issued services and early warning information to do a good job of "Sanxia" weather interpretation and popular science.

For the first time, the China Meteorological Administration and the Ministry of Agriculture and Rural Ministry jointly issued an early warning of the risk of agricultural meteorological disasters to prevent the adverse effects of disasters such as hot air and drought; the two departments further strengthened business research and judgment, and shared meteorological information in a timely manner and information about summer and summer.

Defense suggestion

Subsequent precipitation for the northern sow

The south needs to prevent waterlogging

The Central Meteorological Observatory predicts that from June 26th to 29th, the rain belt is mainly located in the northeast, North China, Huanghuai, Jianghuai, and eastern part of the southwestern region. From the 25th to 27th, the Meteorological drought areas such as Henan, central and western Shandong, northern Jiangsu and Anhui, northern Hubei, and eastern Gansu, and Ningxia will appear more obvious rainfall process, which is more beneficial to alleviate local meteorological drought.

In addition, on the 25th, high -temperature weather in southern Shanxi, central Hebei, Henan, Shandong, and northern Anhui still continued; intermittent high temperature weather in the eastern and eastern parts of South China will appear.

Li Sen analyzed that the northern precipitation process will effectively improve the soil sentiment, which is very beneficial to the growth of seedlings and spring crops in summer. All localities should seize the opportunity to speed up sowing, and the broadcast areas should pay attention to checking seedlings. The weather in the south has weakened the weather, which is conducive to the growth and development of local crops. We must do a good job of clearing ditch drainage, topical medicine, and prevention and control of pests; strengthen early rice management, promote grouting, premature precocations, preventing high temperature, flood prevention, disease -proof, and disease -proof insects. Premature premature aging.
