Pine tree is a treasure, its trunk is a very versatile wood, and it is also a high-quality raw material for papermaking. The resin liquid of pine trees can be used to make rosin and turpentine, but pine needles were basically allowed to rot or burn in the past cutting process, which not only wasted forest resources, but also easily caused forest fires, soil acidification and pests and diseases. Although there is turpentine in pine bark, collecting turpentine will pay a heavy price and get little benefit. A pine tree can only collect turpentine once a year, and the turpentine collected after bark girdling can only be sold for 2 yuan RMB, and it can only be sold for 20 RMB in ten years. Pine trees whose bark has been cut can't become wood, and will die within 8- 10 years because of lack of nutrition, so destructive cutting can only cause resource exhaustion and waste. The collection of pine needles belongs to nondestructive collection (only once a season 1/3- 1/4, or in pieces), which has no influence on the growth of pine trees and can turn waste into treasure. Pine leaves not only have the medicinal value of preventing and treating hypertension, coronary heart disease, diabetes, stroke and Alzheimer's disease, but also have the health care function. Pine needles are rich in amino acids, various fat-soluble and water-soluble vitamins, more than 40 macroelements, various trace elements and crude fiber, which can be used to develop a variety of health foods, drinks and wines that enhance immunity, promote hair growth, reduce blood fat, soothe the nerves and delay aging, as well as skin care products, shampoos and bath products. The residue without pollution and chemical additives in the cooking process is also valuable, which can be used as feed additives and organic fertilizers, and can also be used to cultivate mushrooms, activate a series of industrial chains, revitalize industries such as medicine, health care, aquaculture and chemical beverages, and give play to the role of science and technology in promoting industrial development.
