In the development of modernization,The inevitable agriculture has been deeply integrated into it。Active agriculture with modern production technology has always been the most important development path of agricultural modernization。Facing the impact of climate change,The power of science and technology to the transformation of agriculture is really amazing: Egypt is artificial rainfall、The help of artificial fertilizer and agricultural chemistry,Large -scale planting early cooked potatoes in sandy soil on the west bank of the Nile,All jobs are generally performed like a pipeline,Large agricultural equipment、huge irrigation pipes,Maximum reduction of the impact of drought and high temperature on crops。So how does agriculture cope with climate change? How does climate change affect the development of agriculture?。

Looking at the main food producer in the world,The high degree of modernization seems to be more in line with the standard of agricultural modernization。So,The impact of modern production methods on agriculture can also be seen in the case of Aiwa, USA。Aiova adopts a typical integrated agricultural production method,85%of the land is used for agricultural production。Poultry and animal feces are used for pouring farmland。This sounds seem to meet the requirements of green development,But in fact this seemingly "green" approach triggered a series of environmental problems。For example,Land poured through dung water,Through crack、The dung ditch is finally discharged bet365 best casino games into the Mississippi River,Excessive nitrate contained in wastewater contained in fecal water and agricultural production and life causes the flood of algae and microorganisms,and fish groups and other marine creatures die largely。Climate change means more for some areas including Aiwa、More violent rainfall,The organic matter and nitrate in the soil are more、Rush away faster。This also means the saline alkaliization of the soil and the pollution of water resources,This also affects humans -water that exceeds the standard nitrate will cause great health hazards to the human body。That is to say,When we think we are engaged in green organic agriculture,Large -scale intensive modern production methods are actually on the soil、Water source、Ocean、The creature caused a series of hazards for interrelated interrelated。The same example has been widely appeared in Europe、South America and other countries,Coffee、cocoa、Fruit and other planting areas。The pictures described in "Silent Spring" are common,Even more complicated situations appear,Not only affects the survival of the growers,It also affects the development of the entire world agriculture。
Climate change is a huge challenge for all agricultural areas,Aiovana in the United States faces the crisis of soil salinization and water pollution,Early precocious potatoes in Egypt are also facing the risk of depleting groundwater resources。From the floods or high temperature weather in many places,The impact of climate change has arrived。From the United States、Examples of Egypt can be seen,Big mechanized agriculture based on modern technology cannot continue to cope with climate change and other environmental crises,The agricultural population is sharply bet365 best casino games reduced、Agricultural income is too low、Excessive application of chemical fertilizer pesticides、Frequent replacement seeds、Whees of soil quality、Environmental problems such as water resources are constantly emerging,The problem of this series is actually interlocking。Just send hope in the new rice、corn、Soybean varieties,It is unrealistic to send hopes to be able to withstand that they can withstand water and drought disasters or increasingly toxicity.,Short success is often a more intense environmental problem.。
Multiple measures around soil protection to deal with climate change
For modern agriculture,Coping climate change is not just low -carbon reduction,It does not mean that simply reducing carbon emissions through technical means。The situation facing agricultural response to climate change is complex,It is not simply reducing carbon emissions to solve。In general,Agricultural response to climate change,Pay attention to three aspects of problems。
First, by effectively improving the quality of the soil to cope with extreme weather and pests in extreme weather such as heavy rainfall brought by climate change。This has been confirmed in international experience,High -quality soil can better cultivate water、Resistance to extreme climate,At the same time, the rich microbial system can ensure that the crop has better insect resistance,Reduce dependence on pesticides。Beida Wilderness is a pioneer in the protection of cultivated land,There was a rotation system in the agricultural reclamation area half a century ago,The concept of protecting black land is deeply rooted in people's hearts,has formed a richer black land protection experience。As agricultural technology is widely used in agricultural production,New Fertilizer bet365 Play online games Technology、New farming models are endless,But soil protection is a complex system engineering,Need to cause time、Land、Because of crop、Develop comprehensive supporting measures due to different characteristics such as weather,Improvement of soil quality is not a day's work,There is also support for other factors except technology,If farming methods and social concepts。
The second is to rethink the farming method。Current,Great mechanization is indeed a general trend,It is also necessary,Mechanized agriculture can increase income by reducing costs,But the contribution to sustainable green agriculture is still limited by technology。Although it can be reduced or restricted of chemical fertilizer pesticides through the precise measurement of technology,But there is no mechanical machine that can accurately remove weeds and diseases and insect pests,It is unrealistic to completely abandon fertilizer pesticides。If the concept of pure green organic is cultivated,can only adopt the fine cultivation method of small farmers,This undoubtedly requires a lot of labor。Fewer and fewer agricultural practitioners are currently increasing、In the background of low agricultural income,Ready cultivation lack of implementation conditions。Improve the quality of the soil to achieve more sustainable agricultural development,It may be reduced due to the dependence of fertilizer pesticides, and the output will be reduced within a few years,It is difficult to see income,It is impossible for small farmers,It is also unsustainable。This is the bottleneck that currently restricts green organic agricultural development。To improve soil quality,Develop green organic agriculture,It is necessary to find more possibilities Bet365 app download between mechanization and fine cultivation,It is not enough to rely on the dedication and effort of agricultural practitioners。
Third is to change the concept。As mentioned earlier,It is not enough to rely on the efforts of agricultural practitioners,Copy climate change,To ensure the stability and development of agriculture requires the attention of the whole society。So,The so -called transformation concept,On the one hand, it is to change the public for modern agriculture、Cognition of the concepts of green organic。People are always cognitive with organic green and non -chemical fertilizer agriculture、The concept of the use of straw back to the field is related。For example,Many public opinion reports talk about 100%of straw back to the field is still a proud gesture,It seems that this is a victory in circular agriculture。But in fact,The more the straw is returning the field, the better the better,Some agricultural experts have passed many years of experiment that the best return rate of straw is about 60%。At present, new technologies have achieved the crushing of straw on the upper layer of the soil,Ensure that it can be completely rotted into organic matter,Complete prohibition of incineration, although it is helpful for air pollution,But for soil and crops, there are strong side effects。Because,If you do not pass the incineration,Worm eggs still survive in the soil,Planting in the second year requires more and stronger pesticides,Long this time,Pepbledown and Cordyceps will appear more and more serious。"Silent Spring" may come at any time,Related policies and the public's environmental knowledge, especially agricultural knowledge, should keep pace with the times。On the other hand, it involves the question of environmental bet365 best casino games protection cost,If you want to improve the soil、Practice such as changing farming methods to adapt to climate change,Make sure we have stable food sources in the future,Then you must find a way to give the agricultural practitioners a reward for funds,To offset them to try green organic agriculture、Change farming method、Reduce and even refuse to use fertilizer pesticides、The risk and negative income of the reduction of the output brought by the soil and other aspects。This is not an industrial feeding agriculture、Urban nurturing rural areas or rewards for environmental protection in agricultural practitioners,but the responsibility for the future development of the entire agriculture and the safety of food safety and food safety,This should become the consensus of the whole society。
People's understanding of agricultural modernization is still in the scene of large bet365 Play online games mechanized production,When people imagine the endless field, only one person operates several mechanical homework in the computer program,The amazing and excitement brought by it. In the past two hundred years ago, people stood in front of the rolling factories in the steam engine.。However, the time of transit was relocated,Humanity has spent great energy and financial resources to change the serious consequences brought by "rolling smoke"。So can you foresee the future,If we do not make changes,Whether it takes the same effort to improve the soil、What about the elements of other humans such as water source? From this perspective,Climate Change、Low -carbon reduction、Green organic is an opportunity for agriculture。On the basis of ensuring food safety,Basis of Agriculture -the protection of soil should be attached more attention,In addition to the large mechanized production method,Other forms of planting methods should be tried。The whole society should support green、sustainable、Organic agriculture,Only this,Agriculture can better cope with the challenges of climate change。
