What is the biggest natural disaster for rural crops?

For agricultural growers, their most important income in a year is the income obtained from the planting, growth, and sale of crops after maturity, generally speaking, the most important thing to grow crops is the climate problem, but the climate is very changeable as a relatively changeable thing, usually crops will also be affected by climate disasters, then rural crops are the biggest natural disasters.

Let's introduce what it is. <>

Due to the vast area of our country, it is divided into the south and the north, and the climate is also very different, so rice is usually grown in the south and wheat is usually grown in the north. So the biggest natural disasters for rural crops are usually droughts and waterlogging, with droughts usually occurring in the north and floods usually occurring in the south. When a place is exposed to high temperatures for a long time and there is no rain, the crops in the area may be affected by drought, and the soil will crack, and the crops will not be replenished with enough water, which will reduce the yield and even lead to the death of crops, resulting in no harvest for growers.

If it is in a place where there is abundant rainfall, and the rain is too abundant due to prolonged rainfall, and too much water accumulates in the rice field, and it is not discharged in time, then the crops may be affected by waterlogging, and the roots of the crops may rot at this time, resulting in reduced yield or even death. <>

In addition to the above two disasters, the locust plague.

It is also a very serious natural disaster, and the impact of locusts on crops is very bad. If a large-scale locust outbreak occurs, crops may be eaten by locusts in a short period of time, causing great losses to growers or even no harvest for a year. Although crops are more afraid of natural disasters, under the development of science and technology, there are some measures to deal with drought and flood and other natural disasters such as frost damage, so crops can also ensure yield to a certain extent.

With the development of modern agricultural science and technology, some natural disasters can be effectively prevented, crops will be protected accordingly, and the hard work of growers can be guaranteed to a certain extent.

I think the biggest natural disaster is flooding. Because the flood disaster affects a very wide area, sometimes the flood even passes through more than a dozen cities and counties. The damage caused by floods is not only for crops, but also for people and other property, and it can also disrupt public measures and directly affect the lives of people in most areas.

With the development of agricultural science and technology, the era of relying on the sky for food is gone, and the natural disasters suffered by agriculture now mainly include large-scale high temperature and drought, continuous heavy rain and floods, sudden strong winds and hail, continuous low temperature frost and persistent continuous rain are the main natural disasters for agriculture.

Hello dear, I'm glad to answer for you. <>

Common agricultural natural disasters include: meteorological disasters, such as floods, droughts, low temperatures, frosts, hurricanes, hail, lightning strikes, etc.; Biological disasters, such as crop diseases, insect pests, grass pests, forest diseases and pests, etc.; Geological disasters, such as debris flows, landslides, ground subsidence, soil erosion, land desertification, etc. These natural disasters often lead to reduced agricultural yields and even endanger people's lives.

Therefore, it is necessary to take active disaster mitigation and avoidance measures and post-disaster remedial measures to prevent the occurrence of natural disasters to the greatest extent and reduce the losses caused by disasters. In recent years, China's low-temperature frost damage, floods and droughts have occurred alternately, and disasters such as frost, hail, diseases and insects have also occurred frequently, which have caused great damage to agricultural production and people's lives. Almost every month there is the possibility of natural disasters, how to prevent and reduce disasters scientifically in the middle of the time, and take effective remedial measures after the disaster, in addition to continuously improving the level of disaster prevention, forecasting, and early warning of agricultural chain mountain disasters, and improving the emergency plan, it is very important and necessary to popularize the knowledge of disaster resistance and reduction, improve the emergency management ability to deal with disasters, and enhance the predictability, initiative and initiative of agricultural disaster prevention and relief work.

The above is mine, I hope it helps you.

<> meteorological disasters: mainly including floods, droughts, low temperature frost damage, strong winds, hail, sandstorms, etc., which cause large losses to agriculture. Ecological disasters:

These include overgrazing, deforestation, and reclamation, which are mainly caused by human activities. Biological disasters: including diseases, insects, rats, weeds, etc., there are many types, and they are common throughout the country.

Geological disasters: mainly **, landslides, debris flows, collapses, ground cracks, etc., the outbreak is relatively sudden, and the degree of destruction is greater.

China is a country with many natural disasters, and how to prevent natural agricultural sborts and disasters is the top priority in agricultural spike production activities. Natural disasters are scourges that bring adverse consequences to the survival and social development of human beings due to natural variation as the main cause. Agricultural natural disasters refer to natural disasters that affect the normal progress of agricultural production and destroy crop harvests.

Various natural disasters such as floods in the south and drought in the north, freezing rain and snow, typhoons, sandstorms and sandstorms have brought huge losses to people's lives and social and economic development.

In recent years, China's low temperature frost damage, floods and droughts have occurred alternately, and frost, hail, diseases and insects and other disasters have also occurred frequently, which have caused great damage to agricultural production and people's lives. Almost every month there is the possibility of natural disasters, how to prevent and reduce disasters scientifically in time and place, and take effective remedial measures after rapid response after disasters, in addition to continuously improving the level of agricultural disasters, forecasting, early warning, and improving emergency plans, popularizing disaster prevention and mitigation knowledge, improving emergency management capabilities in response to disasters, and enhancing the foresight, initiative, and initiative of agricultural disaster relief work is very important and necessary.

The monsoon that affects the annual precipitation in China is mainly the southeast monsoon from the Pacific Ocean and the southwest monsoon from the Indian Ocean in summer. Roughly bounded by the Daxing'an Mountains-Yinshan-Helan Mountains-Bayankala Mountains-Gangdis Mountains, China is divided into monsoon and non-monsoon regions, and the precipitation in China is mainly affected by the southeast monsoon and the southwest monsoon. Early or late arrival of the monsoon is prone to flooding.

The monsoon comes early and is prone to waterlogging. The late arrival of the monsoon is prone to drought. The non-monsoon area is not affected by the summer monsoon and belongs to the semi-arid and arid area, so the natural disaster that has the greatest impact on China's agricultural production is drought.

Drought is the most common, most common and most widely distributed climate disaster that has the greatest impact on China's agricultural production.

<> the area of agricultural acacia disaster refers to the sown area of crops reduced by more than 3 percent (including 3 percent) compared with normal years due to disasters such as floods and droughts. Area Affected:

It refers to the sown area of crops that have reduced the yield of crops compared with normal years due to disasters such as floods and droughts. Harvest-out area: refers to the sown area of crops that are reduced by 8 percent (including 8 percent) compared with normal years due to floods and droughts and other disasters.
