Is the material of wheat straw pp?
Straw, also known as straw grass in ancient times, refers to the remaining stems and leaves of gramineous crops such as rice, wheat and corn after ripening and threshing. The straw of rice is usually called straw and rice, and the straw of wheat is called straw.
Before industrialization, farmers used straw in a variety of ways, which were very rich.
For example, in the south of China, people dry rice stalks and store them, which can be used as firewood, weaving cushions, mattresses, brooms and other household items, laying animal pens, feeding livestock, composting, and even making roofs in simple houses, and are rarely directly wasted.
Due to the popularization of coal, electricity and natural gas and the richness of various industrial products in China in the past two decades, the demand for straw in rural areas has decreased, and the treatment of a large number of straw has become a serious social problem. Although it is forbidden by law, farmers in many places still burn straw directly in the fields, causing air pollution, fire and planes can't take off and land normally.
The burning of straw has also caused pollution in Taiwan Province Province, which has always caused public grievances. The Environmental Protection Bureau pointed out that burying straw immediately during harvesting will not only cause air pollution, but also be a better fertilization method. ?
