This paper briefly analyzes the comprehensive defense countermeasures of agro-meteorological disasters, and discusses the defense countermeasures of agro-meteorological disasters from the specific situation, emergency measures and long-term measures of agro-meteorological disasters at present in China.

Key words:

Agriculture; Meteorological disasters; Comprehensive defense countermeasures;

Introduction:

China's agricultural development has long been affected by meteorological disasters and other factors, and different degrees of meteorological disasters will have an inestimable impact on crop yield and quality. With the development of the world, meteorological disasters have become more and more frequent in recent years, such as global warming, extreme weather, drought, flood and drought, and farmers have little ability to take risks in planting. Therefore, the defensive countermeasures of agricultural meteorological disasters have become particularly important. Only in this way can the risks and impacts brought by meteorological disasters be minimized.

1, the specific situation of agro-meteorological disasters at this stage

Meteorological disasters refer to some unfavorable meteorological factors that will directly affect agricultural production. Since the reform and opening up in China, all aspects of the country have developed rapidly. For example, the speed of social development has gradually improved, and the level of urbanization and industrialization has also gradually improved. Because the development at that time was mainly an extensive economic route, only the benefits brought by this development were seen, and the impact of this development model on the environment was not noticed at all. Environmental pollution will become more and more serious in the future, which indirectly increases the probability of meteorological disasters and brings immeasurable economic losses to people. At the same time, it is also accompanied by food safety issues.

According to a survey, during the period from 1999 to 20 10, the agricultural development in China was very slow. Due to frequent meteorological disasters during this period, crops suffered from natural disasters such as drought, frost, low temperature and flood every year. It is estimated that about 500 million mu of farmland was affected by these natural disasters, and the country lost about 5 billion kilograms of grain. With the development of the country and society, the population is also growing rapidly. In order to avoid the recurrence of this kind of disaster and further affect the grain output, measures must be taken to curb this situation. Agrometeorological disasters were unpredictable at that time, so they would suddenly have a very big impact on crops. China is still in the primary stage of socialism, but with the continuous development of the country, the forecasting technology is becoming more and more perfect in the face of these meteorological disasters. At the same time, we can take some corresponding equipment to minimize or avoid the impact of agricultural meteorological disasters. Only in this way can we ensure the efficient production of agriculture and avoid the recurrence of food security problems.

2, emergency measures to prevent agricultural meteorological disasters

2. 1, timely and accurately forecast agrometeorological disasters.

In the process of crop planting, it is first necessary to predict agrometeorological disasters and ensure the timeliness and accuracy of the prediction. Only in this way can we do a good job of protection before meteorological disasters occur and minimize the impact of meteorological disasters on crops. When reporting meteorological disasters, the relevant meteorological disaster prediction departments should accurately report the occurrence time of meteorological disasters and relevant emergency countermeasures to help farmers resist meteorological disasters, thus ensuring the yield and quality of crops.

2.2, strengthen the defense technology of agricultural meteorological disasters.

Agrometeorological disasters have great influence on crop yield, yield and quality. In order to avoid the phenomenon of mending after the sheep is dead, it is necessary to strengthen some defensive countermeasures and technologies of agricultural meteorological disasters to ensure that farmers can prevent the impact of meteorological disasters on crops at the first time. Some common meteorological disaster prevention technologies focus on temporarily changing the climate environment in which crops grow. This defense technology is widely used, such as drip irrigation and smoking to change the growing environment of crops. Among them, drip irrigation can effectively prevent the impact of drought on crops; Smoking can effectively prevent the harm of early frost in the Spring Festival Evening and drought frost in autumn. Therefore, it is very important to adopt effective defense techniques and means in the process of defending agricultural meteorological disasters.

2.3, strengthen the cultivation technology of agricultural meteorological disasters.

On the premise of accurately predicting meteorological disasters, it is necessary to strengthen the cultivation techniques of agricultural meteorological disasters. Because once meteorological disasters occur, the preventive effect of meteorological disasters is considerable after taking measures in agricultural planting technology. The main operation methods include avoiding spring drought, sowing early in time, using reclaimed water to avoid spring drought and so on.

3. Long-term measures to prevent agrometeorological disasters

3. 1, production methods to avoid meteorological disasters

In order to reduce the harm of meteorological disasters to agriculture, it is necessary not only to study the disaster tolerance ability of crops as the main body, but also to formulate some agricultural production methods that can better avoid meteorological disasters, such as forest-friendly, agriculture-friendly and animal husbandry-friendly. In order to avoid forestry meteorological disasters, economic forests can be cultivated to reduce the degree of disasters. In order to reduce the impact of disasters on agriculture, methods such as growing vegetables in greenhouses can be adopted.

3.2, improve the agricultural production environment

Meteorological disasters occur because the environment is polluted by human beings. Therefore, when taking defensive measures to reduce the impact of meteorological disasters, the most important thing is to protect the environment and improve the agricultural planting and production environment. This is the most fundamental countermeasure for meteorological disasters. If the environment is better, the probability of meteorological disasters will be reduced. Specific measures include building terraces, building new water conservancy projects, drilling wells to prevent drought, planting trees and other measures, with the aim of reducing environmental pollution, thus reducing the occurrence of natural disasters.

3.3. Strengthen the research on stress resistance of crop varieties.

In addition to some measures to deal with meteorological disasters, it is also necessary to take precautions from the crops themselves. For example, enhance the resilience of crops, enhance the hardness of crops and reduce the impact of disasters. The specific measures are to study and test new varieties through forestry, agriculture and animal husbandry, and cultivate new varieties through common methods such as hybridization and breeding. This new variety should have drought resistance and cold resistance to enhance the disaster resistance of agriculture.

3.4, post-disaster agricultural meteorological disaster prevention countermeasures

Many times, the impact of meteorological disasters on agriculture is inevitable, so besides studying emergency measures and long-term measures, it is also necessary to study the situation after meteorological disasters in order to reduce economic losses in time. After-the-fact technical countermeasures refer to the remedial measures taken to reduce the impact of meteorological disasters on crops and ensure the rapid return of agricultural production to normal after the impact of meteorological disasters on agriculture. For example, in the event of hail and other disasters, water and fertilize the crops that are not dead in time to speed up the recovery of crops. This countermeasure can also greatly reduce the impact of meteorological disasters on agriculture.

4. Conclusion

To sum up, most meteorological disasters are caused by environmental pollution. These meteorological disasters have a great impact on crops, seriously affecting agricultural output and quality. The frequent occurrence of meteorological disasters requires timely and scientific countermeasures, and at the same time, it is necessary to improve the environment and reduce the probability of meteorological disasters.
