In view of the above situation, the author believes that there are the following main reasons: 1 productivity level, low technology level. 2 The industrial structure is unreasonable. 3 people's understanding is not in place. 4 Straw itself has a small density, which is the most important and direct cause, and has long plagued us. The natural density of straw is usually 0.03~0.05, which is not conducive to transportation and storage, which seriously affects the deep processing or secondary development and utilization of straw. Therefore, the first high-density compression of straw is the key to solving its transportation, storage and deep development. Only high-density compression can create favorable conditions for the circulation and deep development of straw. At present, in the field of straw development and utilization, there is still huge potential in resources (3.4 billion tons of idle resources per year); there is still a lot of room for development in technology, especially in terms of biotransformation; and the market demand is large and exists. With unlimited business opportunities (there are hundreds of millions of tons of resources every year, there are hundreds of millions of tons of products, there are billions of yuan or billions of wealth).
In recent years, some domestic manufacturers have used mechanical means to compress straws to varying degrees (usually 0.1 provincial-level scientific research projects. After several years of efforts, they have opened up a new way for straw to use, which is to compress straw at a high density. It is a block-shaped feed. It is made from straw such as corn and is compressed into high-temperature and high-temperature compression into a block feed. The main innovation is high density (0.71 tons/m3, which is very convenient for storage, circulation, non-flammable, sterilization and sterilization). Insects, and long-term preservation does not degenerate. The processed block-shaped feed is matured, has a paste-like aroma, improves palatability, has no additives, and has a good color. It is a pure natural green feed. Feeding is safe and convenient, and nutritious. The feeding rate can reach 100%, which is good for digestion and absorption, and can meet the requirements of crude fiber for ruminants. After testing, the nutrient level of corn stalk briquette feed is comparable to that of Leymus chinensis.
This straw briquetting feed, if used in combination with an effective microbial preparation, will improve its nutritional quality and level, which is a good thing.
In order to produce this straw briquetting feed, in recent years, Hebei Huaxing Haoyu Agriculture and Animal Husbandry Technology Co., Ltd. has absorbed domestic and foreign experience and developed the “Lutong†brand series of straw (grass) compression complete sets, specifically 3000, 2000 and 1500. Type, 800 type. After several years of trial operation, the sound is technically advanced and mature in technology. Since its inception, it has been recognized and welcomed by users. The straw feed or briquetted grass that is compressed by this sound is now in China or abroad. In short supply, this project has attracted the attention of relevant government departments. This set of sound is especially suitable for the construction of factories with rich resources, convenient transportation, power and sound, and also brings opportunities for the adjustment of industrial structure of township enterprises. The deer copper brand series straw stalks are used to compress and set the sound. Generally, the investment can be recovered in the same year, and each production line can provide employment opportunities for 10 to 50 people. Production of 10,000 tons of briquetting feed for aquaculture is available for 3000. ~4000 cattle for 1 year of roughage consumption. At the same time, the feed is digested and absorbed by the cattle to absorb the abdomen, most of which form feces, which are used to make biogas for people to use. The rest becomes about 10,000 tons of organic fertilizer. Farmland, reducing the input of chemical fertilizers, developing ecological agriculture, reducing straw burning and optimizing the environment. The project is popular among farmers, herders, urban and rural residents, and can drive planting, aquaculture, manufacturing, processing, and transportation. Good projects such as benign development. Especially the "Lutong" brand 800 type sound, can produce about 0.5~0.8 tons per hour, more suitable for one household or one village to organize production, but also less investment, less risk, A good project that works quickly (as shown).
It can be seen from the above analysis that the technology of “Deer Copper†brand straw (grass) compressing sound and its briquetting feed is a good project with significant economic, ecological and social benefits. From a macro perspective, it can improve the quality of life of our people, alleviate the pressure of land and food in China and the pressure on natural pastures, and solve the big problem of food and animal competition. It fully conforms to the spirit of the "Three Rural Issues" and the scientific development concept of the "16th National Congress" and should be promoted as soon as possible to satisfy the society and benefit the people.
