What is the current drought?How does it affect autumn grain?How to deal with harvest?

Relevant departments and localities are fully fighting high -temperature grasping fields and saving watering and solid.

It is more than a month to harvest in the large area of ​​autumn grain. It is the critical period of the growth and development of autumn grains and the formation of yield. Affected by high temperature and drought weather, the main producing area of ​​the south was heavier, and local waterlogging in the main production area in the northern part of the northern part was threatened to the production of autumn grain. On August 22, the four departments of the Ministry of Agriculture and Rural Affairs, the Ministry of Water Resources, the Ministry of Emergency Management, and the China Meteorological Administration jointly issued an emergency notice, requiring the relevant areas to not relax and grasp the various tasks of disaster prevention and mitigation, and go all out Droughts to defend the bumper harvest of autumn grains.

What is the current drought?

Meteorological drought continues to develop, and the catastrophe crops are mainly medium rice, summer corn, soybeans, etc.

"In the summer, there are rain eighteen rivers, and the river is not broken in the summer. This drought is almost burnt corn." Dingxi Green Agricultural Company, Fuquan City, Guizhou Province, has circulated 1,000 acres of cultivated land this year to promote soybean corn band -shaped planting model. In the case of severe drought, the person in charge Luo Canjiang was sweaty, and the farmers were organizing farmers to quickly water the crops.

Hydrogen drought has been seen only for many years. According to the data released by the Ministry of Water Resources, as of August 17, the water level in the Yangtze River and Dongting Lake and Poyang Lake were 4.85-6.13 meters lower than the same period of the year. Meteorological drought is heavier compared to the same period of the same year. Since late June, the Yangtze River Basin has high temperature weather, especially the east to the middle and lower reaches of the Yangtze River in the east of the Sichuan Basin. Most of the regions have less precipitation than the same period of the year. The Central Meteorological Observatory continued to issue meteorological drought orange warnings on August 26. It is expected that there are medium to heavy rain in some areas of Henan, Anhui and other places, which will be beneficial to the relaxation of meteorological drought. Essence

Agricultural drought has a lagging effect. It is often after a period of time when the meteorological drought occurs, and the insufficient soil moisture will cause crops, grasslands and pastures to be expressed. For the southern rice, the dumping period is the most sensitive to temperature. If it encounters drought during this period, it will have a great impact on the subsequent strong rate. According to the agricultural situation of the Ministry of Agriculture and Rural Affairs, as of August 22, the southern crops were 45.24 million mu due to high temperature heat and drought. The catastrophe crops are mainly grain crops such as medium rice, summer corn, soybeans, as well as economic crops such as vegetables and fruit trees.

The relevant person in charge of the China Meteorological Administration said that in general, this year, the southern drought is characterized by high temperature time, absolute temperature value, and wide coverage. At the same time, the less rainfall has led to an increase in the amount of evaporation in the field and exacerbating the influence of drought.

How does drought affect autumn grain?

Did not change the fundamental aspect of stability of food production

"Autumn grain is the big head of a bumper harvest. The more drought, the more we need to strengthen the field management. This high -yield corn, water and fertilizer, can't do whatever you do." The corn that has been scrambled. According to the agricultural situation of the Ministry of Agriculture and Rural Ministry, the dual -season late rice in the south is currently in the extraction period of pregnancy, and the medium rice is pumping and flowing flowers and grouting. The northern spring corn began to grout, and summer corn began to pump the maxoli, and the soybeans entered the flowering pod period. This year, the area of ​​autumn grains in the country has increased steadily, and autumn grain crops in most areas have grown well. Although the current autumn grain production is facing challenges such as high temperature and drought weather, it is still conditional and foundation for the harvest of the autumn grain.

On the one hand, there are triads to open up drought -resistant water sources, and crop irrigation water is guaranteed.

A few days ago, on the main irrigation river in Daming Village, Huangsha Street, Yueyang County, Hunan Province, volunteers lifted their trousers and stood in the muddy canal, risen in the heat, rented excavators, and used tools such as hoe and iron. , Dredging the water canal, and also organized villagers to use small pumps to pump water to irrigate farmland. A total of more than 10 kilometers of water canal, an effective irrigation area of ​​more than 1,000 acres.

The Ministry of Water Conservancy stated that the current irrigation water sources and urban and rural water supply of large and medium -sized irrigation areas are guaranteed. Drought cultivated land is mainly distributed at the end of the irrigation area and "Wangtiantian" without irrigation facilities; The stream is a decentralized water supply project of water source. Considering that the current peak of agricultural irrigation water, if the situation of dry water continues to develop, it may affect some agricultural irrigation of some along the river irrigation district.

On the other hand, the impact of drought on the production of autumn grain is partial, and it does not change the fundamental fundamentals of stability of food production.

According to the relevant person in charge of the Ministry of Agriculture and Rural Ministry, any natural disaster will affect the normal growth process of crops. Severe drought will have an impact on the production of autumn grain, but from the perspective of the overall situation, the area of ​​autumn grains has increased steadily. At present, it is only local areas that are affected. Some regions with irrigation conditions in the south have sufficient light and heat, and the crops are better. In addition, some disasters or unique areas in the south can make up for the losses caused by the disaster by replenishing crops such as beans, potatoes.

How to deal with drought and ensure the harvest of autumn grains?

Work together to carry the responsibility, combined with actual detailed measures

Work together and take a lot of measures to take the harvest.

In the Yankou Town of Shouxian County, Anhui Province, a drilling machine supported the red parasol. Several staff members were busy wearing straw hats. Provide watering sources. As of 18:00 on August 20, agricultural technicians have been arranged to conduct a total of 219,600 people on the spot of agricultural technicians, with an irrigation area of ​​83.857 million acres. In the hot sun, in Shuangzi Hall Village, Shidong Town, Shidong Town, Suining District, Sichuan Province, villagers sprayed soy seedlings with the help of drought -resistant service vehicles. The relevant person in charge of the Agricultural and Rural Bureau of Mianyang City, Sichuan Province said: "Since the drought, we have established 9 agricultural disaster prevention and mitigation emergency teams to penetrate the heavy drought, salt pavilion, Ziyi and other places, and guide them in the fields. Farmers scientific drought resistance. At the same time, the city also comprehensively inspected and maintained irrigation facilities such as spray irrigation and drip irrigation.

The party and government are responsible for the safety of the safety of food.

The four departments such as the Ministry of Agriculture and Rural Affairs issued an emergency notice on August 22, requiring agricultural rural areas, water conservancy, emergency, meteorological and other departments at all levels to continue to carry out catastrophic weather, especially high -temperature drought forecasting, and timely issue early warning information. Refine the impact of high temperature heat and drought in the county, classification, and crop science, and sort out proposal measures for disaster and disaster mitigation.

The water conservancy department strengthened the scientific dispatch management of water sources such as rivers, rivers, lakes, and libraries, strived to ensure the demand for agricultural irrigation water, dynamically adjust the water engineering scheduling plan, accurately connects each irrigation area, and carefully calculates each party's water to ensure the critical period of crop growth. Use water. Preparation and improvement of drought resistance plans, adopting measures such as emergency water adjustment, new water sources, temporary rack pumps, and peak wheel irrigation should be adopted to ensure drought -resistant emergency water. Emergency departments have timely initiated the adjustment of emergency response, preset the force of emergency offices and flood control materials and equipment, organize the development of water and water delivery and the living assistance of the affected people to ensure the safety of the people drinking water. The meteorological department has timely transfer operations to the arid and disaster -stricken areas, prepares feathers such as rainfall rockets, and guides all places to carry out artificial rainfall operations in a timely manner.

Division conditions are implemented to implement anti -high temperature and heat -harmful drought measures, and measures and increase in production and increase in production are stable and increasing.

The relevant person in charge of the Ministry of Agriculture and Rural Affairs said that at present, we must go all out to the high temperature grasp of the field tube, keep watering and solidify, and consolidate the foundation of autumn grain harvest.

On the one hand, in areas with irrigation conditions, according to the development of the drought, we will implement key measures such as deep water cooling, small water diligence, and flowing heat dissipation. In areas such as hilly house, "Wangtiantian", and the end of the irrigation area, water sources should be sent through machinery, machine wells and other water lifting water to seize the opportunity to carry out artificial rainfall. Drought resistance and water retention agents and other operations; for the heavy or even harvested plots, it is necessary to replace the late autumn crops such as sweet potatoes and miscellaneous grains in a timely manner, and a suitable region can be cut into regenerative rice.

On the other hand, the medium rice that causes a decline in high temperature and heat damage, closely linked to farm, seized the limited grouting time, scientifically increased spike fertilizer, sprayed leaf fertilizer, enhanced photosynthesis and grouting rates, and worked hard to increase granules to make up for it to make up for it to make up for it. Decreased losses. Double -season late rice is in the period of extracts on dulbin. It is necessary to focus on preventing possible Fuqiu and drought, make a planning plan for drought resistance in advance, dispatch the water source in advance, increase the gestational fertilizer in a timely manner, and implement large water pregnancy ears, water pumping, inch water promotion to promote Suitable measures such as spikes and moist grains to promote growth and development.
