Bark, from the perspective of economic value, is also a "treasure," and it is a pity to discard or burn it. Some people calculate that the bark accounts for about 10% of the xylem of various trees. Researchers believe that the bark can be fermented into fertilizers or substrates. However, due to its strong antibacterial properties, it is not easily impregnated with water and rot, so it is one of the organic materials that are difficult to ferment. Generally, the fermentation auxiliaries are difficult to deal with (fermented bark fermentation aids, etc.), affecting the fermentation of materials. The most important factors of speed and temperature are: dosage of fermentation aids, nutrient content, moisture content, start-up temperature, air permeability, pH, material fineness and so on. To speed up the fermentation, increase the fermentation temperature, in addition to properly increase the amount of Golden Bark bark fermentation additives, but also should pay attention to the following points: 1, adjust the carbon and nitrogen ratio. Can improve the nutritional structure of pine bark carbon and nitrogen ratio is generally 135:1, need to add more nitrogen source, can be added fresh chicken manure, urea water, brown sugar water, phosphate rock powder, etc.; 2, increase nutrition. Appropriate urea water, brown sugar water, rice bran can be added. Because brown sugar water can increase nutrition and sticking ability to bark bark fermenters and rice bran; increase the amount of rice bran so that rice bran is not only used as a diluent, but also allows it to participate in fermentation as an auxiliary material. The nutritional properties of rice bran are good. It is easy to fill the gap between the pine bark particles. After the brown sugar water is added, the mixture of rice bran and goldfish fermentation aids can be affixed around the bark particles, which increases the number of functional microorganisms per unit surface area, and also provides the microbial strains. With better nutrition, water retention, nutrition, and fermentation opportunities are greatly improved at the same time, so the fermentation intensity will be greatly increased, and the temperature will rise faster, more intensely and violently. 3, pay attention to water conservation. In order to increase the bark moisture content and water retention performance, should be soaked before fermentation for more than 24 hours, the general principle is to allow the water to fully penetrate the inner core of the granules, so that the bark is fully wetted to ensure the microbial fermentation of the moisture requirements. The addition of brown sugar water and rice bran can also improve the water retention performance. During the fermentation process, pay attention to the nutritional effect of thin brown sugar water. In addition, it should be properly covered. The bark can be covered with a breathable cover such as straw or straw to preserve moisture and humidity. Because the strains of Golden Bark bark fermentation aids are aerobic microorganisms, the oxygen content of the fermentation materials must be sufficient, and attention should be paid to overturning and increasing ventilation. When necessary, oxygen supply measures should be taken, such as setting up vent holes in the material pile, turning over, natural ventilation, and forced ventilation of the bottom blower.

Stevia
Stevia sweeteners are derived from the leaves of the Stevia rebaudiana (Bertoni) plant, an herbal shrub native to South America. The stevia plant has been used for food and medicinal purposes for hundreds of years, and its leaves and crude extracts have been sold as dietary supplements. Purified extracts of the sweet substances found in the stevia leaf, called steviol glycosides, are considered to be generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA). However, whole stevia leaves and crude leaf extracts are not permitted to be sold as sweeteners in the U.S. because there is not enough toxicological information on these products, according to the FDA. Stevia sweeteners are made by extracting steviol glycosides from the leaves of the stevia plant and purifying them to remove some of the bitter attributes found in the crude extract.
