The reporter learned from the Shandong Rural Professional Technology Association that a new type of degradable plastic film has been successfully developed in Shandong. It can completely replace traditional plastic film for agricultural production and effectively solve the “white pollution†problem that plagues agricultural production.
According to reports, this liquid film is made of natural polymer materials such as lignin, cellulose, soil improver, and soil water retention agent, which can be naturally degraded and converted into organic fertilizer, water, and carbon dioxide without manual recovery. "White pollution".
Traditional mulch requires artificial smashing to produce seedlings. This new type of mulching crop can naturally emerge, and it can also reduce fertilizer application. Compared with the use of plastic mulch, the workload is only 20% of the plastic mulch.
According to experts, this new type of plastic film also has a good effect of increasing production. Because of its strong permeability to water, it is conducive to the growth of crop roots. In field applications such as peanuts, potatoes, and cotton, it can promote root growth, enhance drought resistance, reduce disease occurrence, and significantly increase yield.
Pebbles are evenly distributed, hard in quality, bright and simple in color. They have the characteristics of compression resistance, wear resistance and corrosion resistance. They are an ideal green building material.
Pebbles are widely used in public buildings, villas, courtyard buildings, pavement (the pebble road paved in the park often has the effect of prolonging life), Park rockery, bonsai filling materials, garden art and other high-grade superstructure. It not only carries forward the ancient oriental culture, but also reflects the western classical, elegant and primitive artistic style.
