Experts believe that burning straw is particularly harmful to the environment. On the other hand, the weather temperature rises slowly, and burning straw is easy to cause mountain fires. All localities have also begun to implement the policy of prohibiting rural farmers from burning straw. Suining Town, Yongning County, Yinchuan City, Ningxia Hui Autonomous Region has issued a notice on printing and distributing the Implementation Plan for Banning Burning Crop Straw in Suining Town in 2023.
It is clearly emphasized that in order to further improve environmental quality, ensure air quality and effectively prevent and control air pollution. The whole town completely banned the burning of straw, thoroughly cleaned up the accumulated crop straw, and completely eliminated the hidden danger of burning, so that the burning of straw in the area under its jurisdiction was zero during important holidays and spring ploughing production, and the slogan of "no fire and no smoke" was shouted throughout the town.
Disadvantages of straw burning
When burning straw, the three pollution indexes of sulfur dioxide, nitrogen dioxide and inhalable particulate matter in the air all reached the peak, in which the concentration of sulfur dioxide was 1 times higher than usual, and the concentration of nitrogen dioxide and inhalable particulate matter was three times higher than usual. The smoke from straw burning will reduce the visibility and visual range of the air, directly affect the normal operation of civil aviation, railways and highways, easily lead to traffic accidents and endanger personal safety.
Burning straw can easily ignite the surrounding flammable materials, leading to "burning camp". Once a fire breaks out, it is often difficult to control and cause economic losses. Especially near the mountain forest, the consequences are even more unimaginable. When straw is burned into the ground, microorganisms on the surface are burned to death, and humus and organic matter are mineralized. Burning straw in the field destroys the balance of this biological system, changes the physical properties of soil, intensifies soil hardening, destroys soil fertility and threatens the sustainable development of agriculture.
