The application of humic acid in agriculture China is a big country in agriculture, but with the continuous increase of population and the deterioration of arable land, the per capita possession of land is decreasing, and it is urgent to strengthen agricultural development. One of the material foundations for the development of agriculture is the development of the fertilizer industry. Therefore, the chemical fertilizers will come out on stage, which not only solves the food problem of more than one billion people, but also brings huge economic benefits to humanity. As everyone knows, a large number of chemical fertilizers have been used, resulting in a decline in the quality of cultivated land and adverse effects on the ecological environment. The 21st century is a time of green revolution. It is very important to develop and produce green and environmental-friendly fertilizers. In recent years, through the joint efforts of numerous scientific research institutions and famous humic acid companies, the use of humic acid fertilizers to improve the soil and improve the fertilizer efficiency have achieved great results. Progress. The scientific and rational application of humic acid in agriculture and the development and production of humic acid products are practical and feasible ways for the development of organic-inorganic compound fertilizers in China. Practice has shown that the use of humic acid produced compound fertilizer to increase fertilizer utilization, improve the soil, increase the resistance of the crop and improve the quality of agricultural products has been gradually people's attention, is known as the third-generation chemical fertilizer. The application of several products will be described below. (1) Biologically Active Additives This product is the original powder of humic acid. It is a natural polymer organic polymer with a complex structure and contains a large number of active groups such as carboxyl, sulfhydryl and phenolic hydroxyl groups. Adding the product to the compound fertilizer has the following effects: improving the low-yield soil; increasing the utilization rate of the chemical fertilizer; stimulating plant growth and development; increasing the resistance of the crop; improving and improving the quality of the agricultural product. The general dosage is 15 kg compounded production per ton of compound fertilizer. (2) Nitrohumic humic acid This product is prepared by oxidation and nitration of preferably active raw coal and nitric acid. The product has stronger biological activity than pure humic acid. The humic acid compound fertilizer prepared by using this product is 10-20% higher than that of other differentiated fertilizers. It is called "enhancing agent" in foreign countries and is called "synergist" in China. (3) Ammonium Humate for Agricultural Use This product is called ammonium hydroxide for short, and it is a kind of multifunctional organic nitrogen fertilizer produced by ammoniating higher raw coal with high humic acid content. Contains humic acid, available nitrogen and a variety of trace elements. Application in agriculture can promote crop growth for a long time, give full play to the "joint effect" of multi-nutrient elements, increase the utilization of nitrogen, phosphorus and potassium, increase soil fertility, stimulate crop growth, enhance the resistance of crops, improve China's fertilizer production and The situation of severe imbalance in the proportion of NPK in use. Farmers generally believe that the effect of ammonium bicarbonate is “burst, fierce, and short”, while the effect of ammonium sulfate is “slow, steady, and long”. Because humic acid contains carboxyl groups, phenolic hydroxyls and other acidic functional groups, it has strong ion exchange capacity and adsorption capacity, which can reduce the volatilization loss of ammonia nitrogen and improve the utilization rate of nitrogen fertilizer. It is a new type of organic fertilizer with great promise and promotion value. (4) Sodium humate for agricultural use This product is produced by reacting raw coal with good activity and sodium hydroxide. This product is combined with nitrogen and phosphorus needed by crops to become a multi-functional high-efficiency compound fertilizer, which has the advantages of buffering acid and alkali, ion substitution, improving soil, warming seedlings, regulating growth, and improving quality. It is used as soil acidifying agent, plant growth stimulating hormone, fertilizer improving agent, and crop nutrient spraying liquid. This product can be diluted spray or mixed application, can also be matched with other fertilizer compound production. (5) Potassium humate for agricultural use This product is a non-homogeneous aromatic hydroxy acid salt with black appearance or powdery solid. It is easily soluble in water and the aqueous solution is alkaline. It is rich in carboxyl, hydroxyl, phenolic hydroxyl, sulfhydryl, methoxy and other active groups. After applied to the soil, it can react with soil minerals through complexation, chelation, and adsorption to improve soil structure and activate soil nutrients. Improve soil fertility and water retention. The improvement effect on low-yielding fields, acid soils, albic soils, saline-alkali soils, sand-alkali lands and sandy lands is significant, and more prominently, it can increase the content of soil available potassium (especially water-soluble potassium) and reduce the fixation of potassium in the soil. Promote the release of insoluble potassium, improve the supply of soil potassium, increase crop absorption of potassium. Combined with nitrogen and phosphorus needed by plants, it can be used as a multifunctional compound fertilizer, as a soil improver, as a plant growth stimulator, as a fertilizer enhancer, and as a crop nutrient spray. (6) Potassium nitro-humate This product is compared with pure humic acid potassium: its biological activity is stronger. Improvement of saline-alkaline soil, albic soil, red soil and rice nursery bed soil; increase the utilization rate of nitrogen, phosphorus and potassium in fertilizers; stimulate the growth and development of crops; enhance the drought resistance, cold resistance and disease resistance of crops; Quality. Japan has promoted this product as a potash for commercial use and achieved good results. This product can be diluted spray or mixed application, can also be matched with other fertilizer compound production. Application of Humic Acid in Livestock Husbandry Humic acid substances, used in animal feed additives, have been widely used in many countries such as the Soviet Union, Japan, and Europe and the United States. Adding a small amount of humic acids to the feed can make the fat in the feed difficult to use. Oxidation reduces bad odors and promotes rapid decomposition of feed in digestive organs. Can improve the activity of digestive enzymes, so that the animal's appetite increased, weight gain, the incidence decreased. At the same time, the detoxification of ammonium poisoning caused by the addition of urea and ammonium salt to the protein source can speed up the conversion of non-protein nitrogen into amino acid and protein nitrogen in the feed. After many years of efforts, our factory was approved by the Provincial Bureau of Animal Husbandry and Veterinary in 1994. We learned from previous experience that we successfully produced compound cobalt chloride, feed humic acid sodium and aquaculture by using humic acid as carrier. Effective agent. The detailed performance is as follows: (1) Compound Cobalt Chloride This product, also known as "Corrosive Cobalt Powder," is made up of a variety of trace element polymer chemical agents.
