Biofertilizer - "good head" of organic agriculture
"A crop of flowers depends entirely on fat." Today, as China's accession to the WTO, agricultural production attaches importance to the development and promotion of the use of biological fertilizers, breaking through the "green fortress" encirclement, has become a top priority. Paying attention to the application of biological fertilizers is an inevitable historical development. In the middle and late 20th century, global fertilizer fever appeared in less than 30 years. In particular, the abuse of chemical fertilizers increased production costs, resulting in soil compaction and reduced fertility, so that the fruits were not fragrant beets. What's more, it pollutes the environment. Apart from causing a significant increase in nitrate and nitrite content in strong carcinogens in the soil, it has also become an important cause of water eutrophication, climate warming, excessive levels of groundwater and drinking water carcinogens. Therefore, with the growing demand for environmental protection and return to nature, vigorously promoting the application of biological fertilizers has become the mainstream. The so-called biological fertilizer refers to the use of bioengineering technology to make certain bacteria with special functions into "fertilizers". These "fertilizers" themselves have no fertilizer effect, but after they enter the soil, they can continue to grow and reproduce. Phosphorus and potassium minerals that cannot be used in agricultural crops that exist in large quantities in the soil are decomposed, and the nitrogen that is released from the atmosphere is fixed and becomes nitrogen, phosphorus, and potassium nutrients that the crop can absorb and use. At the same time, these bacteria in the metabolism process will also produce many extraordinary metabolites - enzymes, such as fiber enzymes can be straw in the long-term cellulose will be broken into sugar and finally into humus; dissolved protease can make The protein in plant residues becomes an essential amino acid for crop growth... In addition, the activity of bacteria also loosens the soil in the plant rhizosphere, promotes root growth, and degrades the lead, kun, and mercury in soil due to the long-term application of fertilizers and pesticides. , chromium and other heavy metals and nitrite, so that the crop to achieve high quality and high yield. Therefore, after World War II, as the use of bacteria turned from warfare to peace, biological fertilizers have received increasing attention, such as the use of bacteria to ferment sawn in Canada, Japan's use of yeast, actinomycetes to ferment rice husks, and human and animal waste. Biological organic fertilizers and so on. Scientific research shows that the biological fertilizer effect is high and low, and the decisive factor lies in the availability, high efficiency, genetic stability, and adaptability to various ecological factors of the bacterial strains. In particular, the effective combination of various strains has always been to improve the quality of biological fertilizers. The essential. After years of hard work, in 2000, under the support of experts from the Chinese Academy of Military Medical Sciences and other experts, Guangxi Lida Agricultural Development Industry Co., Ltd. used modern biological engineering technology and special techniques to successfully combine 15 strains of special bacteria and achieved New breakthroughs in bio-fertilizer technology. According to scientific experiments and multi-field experiments conducted by Daejeon, the 15 strains in Lida Bio-fertilizer are not only highly-targeted, but also complementary, capable of efficiently and rapidly exerting nitrogen fixation, phosphate release, and potassium release, and at the same time The production of more than 10 highly active biological enzymes can accelerate the decomposition of lignin, cellulose, proteins and polysaccharides, transforming the formation of a large number of organic acids such as humic acid, gibberellic acid, etc. It is an ideal growth regulator for plants. These bacteria can also degrade the toxic substances in soil and the chemical fertilizers and pesticide residues in agricultural products, and categorize and catalyze different types of organic substances, especially the artificial induced transformation of humus, thus showing good fertile soil, clean soil, and environmental protection. High-yield, high-quality, low-consumption effects, promote the transformation of agricultural products from inorganic to organic. At present, the biological fertilizer has been included in the National Spark Program development product by the Ministry of Science and Technology. Therefore, not long ago in our district, “a seminar on the promotion and application of bio-fertilizers in the production of pollution-free agricultural productsâ€, experts agreed that in order to quickly change the overuse of chemical fertilizers in agricultural production in our district, excessive pollution of harmful substances resulted in a decrease in output and quality. The problem must pay attention to promoting the use of Lida Bio-organic fertilizer.
