The policy of banning straw burning in rural areas has lasted for more than a decade, and although it seems to be conducive to reducing air pollution, it has not had much impact on the overall environmental pollution. Compared to the emissions of vehicle exhaust, industrial exhaust, animal exhaust and swamp gases, the pollution caused by straw burning is very limited. Although the soot produced by burning straw will be emitted in a concentrated manner at a certain point in time, the total amount is relatively small, and the impact on the atmosphere is short-lived. In contrast, emissions from other sources are enormous, and their devastating effects on the atmosphere and climate change as a whole are more severe. Therefore, compared with other sources of pollution that comprehensively control environmental pollution, the impact of the ban on straw burning is insignificant, and it can even be said that the cart is turned upside down. The state's ban on straw burning brings far fewer benefits than disadvantages in controlling environmental pollution and protecting the environment.
Although a ban on straw burning can reduce PM2 in the atmosphere5. Carbon dust and carbon dioxide gas have a certain alleviating effect on haze weather, but the harm they bring is also very serious. First of all, a large number of straw returning to the field has a great impact on cultivation, it is difficult for seeds to germinate, and it is difficult for crop roots to take root, which is easy to cause drought and death of seedlings and increase the occurrence of pests and diseases, which eventually leads to a decline in grain production and seriously threatens food security. Secondly, when farmers deal with a large number of straws, they tend to pile up indiscriminately, which seriously affects environmental sanitation, and some of the straws will even drift away with the wind and fall into canals, ponds and rivers, and produce sewage after rotting, threatening the safety of drinking water for people and animals. In addition, this waste straw can also block waterways and flow into streams and valleys, increasing the risk of flooding during the flood season. Finally, in the dry autumn and winter, the straw piled up indiscriminately is easy to cause fires and become a major hidden danger of fires.
To sum up, the disadvantages of banning straw burning far outweigh its benefits. The ban on straw burning has seriously affected agricultural production, threatened food security, damaged the ecological environment, and led to many floods and droughts.
According to ** report, China's policy adjustment and changes on straw burning have brought some good news. At present, a number of provinces have begun to implement the conditional straw burning policy, and strive to cancel the straw burning ban nationwide. This is very good news for agricultural production and farmers.
The policy of conditional straw burning takes into account the balance between the actual situation and the environmental impact. The policy stipulates that farmers can only burn straw for a specified time and range to reduce the impact on the atmospheric environment. Through standardized management and control measures, large-scale and disorderly pollution caused by straw burning can be avoided. In the specific implementation process, the relevant departments will strictly manage and monitor the time, place and quantity of straw burning to ensure that it is limited to a certain range and the impact on the environment is controllable.
The implementation of this policy will bring benefits in many ways. First of all, farmers are given the right to burn straw within a certain range, which reduces their burden. The previous ban on burning made it impossible for farmers to dispose of large quantities of straw, increasing the difficulty and economic burden of farming. The current policy can give farmers the opportunity to burn straw under specified conditions, reducing the difficulty of straw disposal, and improving farmers' farming efficiency and food production.
Second, the policy of conditional straw burning can also promote the sustainable development of agricultural production. The ash residue after straw incineration can be used as organic fertilizer, which can be returned to farmland, increase soil fertility, promote crop growth, and improve the quality and yield of agricultural products. In addition, straw burning can also effectively control the spread of pests and diseases, reduce crop losses, and improve farmers' economic income.
Finally, the implementation of the policy of conditional straw burning can also improve the environmental health situation in rural areas. Under the standardized management of the policy, the time and place of farmers' straw burning are limited, which reduces the environmental pollution caused by indiscriminate stacking of straw. At the same time, it will also increase the supervision of the straw burning process to ensure the safety and environmental protection of the incineration process.
In short, the implementation of the conditional straw burning policy not only takes into account the actual needs of farmers, but also takes into account the requirements of environmental protection. The implementation of this policy will bring many benefits, such as alleviating the burden of straw burning on farmers, promoting the sustainable development of agricultural production, and improving environmental sanitation in rural areas.
It is imperative that the ban on straw burning be lifted. With the implementation of conditional straw burning policies in several provinces and the progress towards lifting the ban on burning nationwide, we can see that the state is actively taking steps to solve the problems that have plagued farmers and agriculture for a long time. The lifting of the ban on straw burning has a positive impact on agricultural production, grain production, and the increase of farmers' economic income.
Lifting the ban on straw burning can alleviate the difficulties and economic burden of farmers in disposing of straw. Allowing farmers to burn straw within a specified time and range reduces the difficulty of straw disposal and improves farmers' farming efficiency and grain production. In addition, the ash residue after burning straw can be used as organic fertilizer to return to farmland, increase soil fertility, promote crop growth, and then improve the quality and yield of agricultural products.
Lifting the ban on straw burning could also improve rural sanitation. The implementation of the conditional straw burning policy will standardize the time and place of straw burning by farmers, and reduce the environmental pollution caused by indiscriminate stacking of straw. **Increasing the supervision of the incineration process can ensure the safety and environmental protection of the incineration process. This will effectively solve the problems of straw drifting in the wind and piling up into rivers, and reduce the threat to water sources and the safety of drinking water for people and animals.
However, lifting the ban on straw burning also requires caution. After the ban on straw burning is lifted, strict management and supervision measures are needed to ensure that farmers do not over-burn or pile up indiscriminately when burning straw, so as not to cause greater environmental pollution and fire hazards. ** The protection and management of farmland should also be strengthened, to prevent damage to farmland caused by straw burning, and to ensure the balance and sustainable development of agricultural ecology.
In addition, the lifting of the ban on straw burning must have a set of supporting measures, combined with other environmental governance measures. Only through comprehensive treatment and reducing the discharge of multiple pollution sources can we truly achieve environmental improvement and protection.
To sum up, lifting the ban on straw burning is a significant measure. It can not only ease the burden on farmers and promote the development of agriculture, but also improve the environmental sanitation situation in rural areas. However, before the ban on straw burning can be lifted, strict management and monitoring measures need to be put in place and combined with other environmental governance measures to ensure the sustainable development and protection of the environment.
