Straw burning is not banned in the United States.
One of the reasons straw burning is not banned in developed countries such as the United States and Japan is that the benefits of burning straw are well recognized. Burning straw can burn out the seeds of weeds and insect eggs in the soil, thus reducing the incidence of weeds and pests in crops. In addition, the straw ash produced by burning contains large amounts of potassium and phosphorus, which are natural fertilizers that can improve soil fertility.
Countries such as the United States and Japan have implemented a strict management system for straw burning and are equipped with specialized straw burning machinery and equipment. These equipments are characterized by high efficiency and low pollution, which can effectively control the emission of soot and harmful substances and reduce the risk of pollution to the environment. In addition, these countries have also strengthened the regulation and enforcement of incineration activities to ensure the safety and compliance of the incineration process.
Analysis of China's straw-burning ban policy:
For a geographically large country like China, a one-size-fits-all straw-burning ban policy does not apply to all regions. There are north-south, east-west and developmental differences in different regions, with some places having greater difficulty in environmental management and others having relatively less.
For the less industrially developed and sparsely populated areas, a moderate liberalization of the straw burning ban can reduce the burden on farmers, motivate them to farm, and contribute to the development of the local economy.
However, the importance of environmental protection and people's health still needs to be taken into account when adjusting the policy. Policies should be implemented according to local conditions and management measures should be formulated in the light of the actual situation. The emission of pollutants in the incineration process can be reduced by strengthening management and promoting new technologies and equipment.
