As we all know, rice is the world's most widely grown crop with the largest yield. The annual rice production in China is about 180 million tons. Rice husk is the largest by-product of rice processing and accounts for about 20% of rice by weight. The annual output of rice in China from 1996 to 1997 was 260 million tons, and the annual output of rice husk was about 32 million tons, ranking first in the world. As a solid waste of agriculture and forestry, rice husk straw has been difficult to use for a long time, and its comprehensive utilization rate is currently less than 10%. How to process and use good rice husk? Studying the rational use of rice husks and turning waste into treasure is a significant task before us. Beijing Huaxia Kangyuan Science and Technology Co., Ltd. elaborately prepared the geostrophic soil nutrient soil auxiliaries to solve this problem. Fermented rice husks are high quality materials for flower seedlings and nutrient soils, especially with the development of new landscape trends such as “landless cultivationâ€, “vegetation nurseryâ€, “roof garden†and other modern landscape industries, their economic value has rapidly increased. So how does fermentation use rice husks? Food additives are compounds or natural substances added to food for the purpose of improving the color, aroma, and taste of food, as well as for the needs of anti-corrosion and processing technology. At present, there are 23 categories of food additives, with more than 2,000 varieties, including acidity regulators, anticaking agents, defoamers, antioxidants, bleaching agents, leavening agents, coloring agents, color retention agents, enzyme preparations, and flavor enhancers, nutritional fortifiers, preservatives, Sweeteners, thickeners, spices, etc. Erythritol, Sweetener, Pigment, XOS , Carotene, fish oil Xi'an Gawen Biotechnology Co., Ltd , https://www.ahualyn-bios.com
The main components of rice hull vary greatly in variety, origin, and processing method. Generally, the water content is about 12%, carbon content is 36%, nitrogen content is 0.48%, phosphorus content is 0.32%, and potassium content is 0.27%. The composition of rice straw is similar to that of rice straw, but rice husk has much higher silicic acid content than rice straw. The carbon-nitrogen ratio of rice hulls is as high as 75.6%, which is one of the organic materials that are difficult to ferment. The fermentation is very difficult, and it is difficult for general fermentation auxiliaries to “uniformize†them.
Therefore, rice husk fermentation should first use urea "ammonia" treatment, or use livestock urine mixed ammoniation treatment in order to obtain a better fermentation effect. The specific operation is as follows:
1. Prepare one ton of rice husk, 4kg of urea and 10kg of rice bran.
2, adjust the moisture content of rice hull moisture content, and then based on the required moisture content of 60% fermentation, 500kg of water per ton of material (soaking), stacked and placed more than 24 hours.
3. After 24 hours of ammoniating and stacking, when the moisture content of the rice hull reaches 60∼65%, 4kg of urea is mixed with 50kg of water to make urea water and evenly sprinkled on the rice husk pile.
4. After the “ammonia†treatment of condiments and bacteria is added, after 12 hours, 2kg of Tribolium microbial fermentation aids are mixed in 10kg rice bran, and then “dilutedâ€, and then evenly sprinkled on the rice husks and accumulated. The stacking height does not exceed 2m, and the area does not exceed 50m2.
5. Cover the cover immediately after the cover is tipped and piled up to achieve insulation and moisturization. Note: For rice husk accumulation and fermentation, we must shut down three levels of “heat preservationâ€, “Moisturizing†and “aerationâ€. Generally, the fermentation can be completed within 20∼25 days. The accumulated temperature of fermentation is 1000∼1200°C. The key technology to start the first week of fermentation is temperature control and management, especially the warming and moisturizing are the most important. When the fermentation temperature reaches 65∼70°C and continues for 36 hours, the first turning can be performed. After that, until the fermentation is completed, the “core†of the management during this period is to perform “ventilation†under the premise of “insulationâ€. "," "moisturizing" management.
In addition to the above urea ammoniation pretreatment, 200 kg of livestock excreta can also be used to blend in a certain amount of water and evenly mixed and mixed with a ton of rice husk. Other operations are the same as above. This is an alternative. Details can be consulted: Beijing Huaxia Kangyuan Technology Co., Ltd. Telephone Toll Free Hotline:
