Is Zizania latifolia useful?

More than half of the products of crop photosynthesis exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, and is a valuable biological resource. It may be a good organic fertilizer to mix the crushed straw of Zizania latifolia with livestock manure. There are 24 agricultural states in the United States, and a large number of straws need to be treated every year. In some places, straw is used as building materials, and the whole bundle of straw is extruded with high intensity and filled into the walls of new houses. According to media reports, an international patent technology in Germany mixes composite industrial and agricultural wastes and recycled materials, and makes them into light, efficient and energy-saving building materials through special treatment, with high thermal insulation efficiency, strong fire resistance and good sound insulation performance; In China, the production of clay brick consumes more than 70 million tons of standard coal every year, and the energy consumption of building air conditioning using traditional brick materials is also greatly increased, so replacing clay brick with straw is undoubtedly a good method of environmental protection and energy saving. In addition, straw can also be used to make rayon and rayon, furfural, maltose and alcohol. According to the research results of renewable clean energy laboratory of China University of Science and Technology last year, straw can also be used to produce bio-oil. The oil yield is over 50%, and the price is only 43.2% and 63. 1% of diesel oil and heavy oil.
