Abstract
The invention discloses a biochemical chelate fertilizer and a preparation method thereof, wherein the fertilizer consists of ammonium sulfate, monoammonium phosphate, urea, potassium sulfate, boric acid, ferrous sulfate heptahydrate, zinc sulfate heptahydrate, copper sulfate pentahydrate, bacillus natto fermentation products and a chelate stabilizer. Through a specific fermentation process, the polyglutamic acid compound is generated by fermenting bacillus natto, and is chelated with trace elements on line in the fermentation process, and then is granulated with major elements of nitrogen, phosphorus and potassium to obtain the product. The biochemical chelating agent in the product is degradable, ecological and environment-friendly. The product has balanced nutrients and easily absorbed nutrient elements, and can obviously improve the yield and quality of crops.
Description
Technical Field
The invention relates to the technical field of agricultural fertilizers, in particular to a biochemical chelate fertilizer and a manufacturing method thereof.
Background
China is a big agricultural country, and cultivated land which accounts for 7% of the world is used to cultivate 21% of the population of the world. The fertilizer is used as grain of grain, the grain yield is increased by 50% due to the contribution of the fertilizer, but soil heavy metal exceeding standard, soil hardening, secondary soil salinization and soil acidification in China are caused by unscientific and reasonable fertilization. The unreasonable fertilization mainly shows that the fertilizer is excessively fertilized, the fertilization method is improper, and the fertilization structure is unreasonable. In recent decades, in order to pursue high yield, people apply excessive chemical fertilizers, so that the fertilizer loss is serious, water quality eutrophication is caused, and nitrate exceeds the standard. The unreasonable fertilization structure mainly shows three-fold lightness: heavy fertilizer and light organic fertilizer; heavy nitrogen fertilizer, light phosphorus potassium; heavy major elements, light medium trace elements. Excessive administration of an element increases antagonism against the element, e.g. excessive administration of nitrogen causes calcium deficiency; excessive potassium can reduce the effectiveness of calcium, magnesium and boron; the excessive phosphorus can reduce the effectiveness of calcium, zinc and boron, cause crop nutrient deficiency, serious crop diseases and poor quality of agricultural products.
Soluble metal salt containing medium trace elements is added into the fertilizer, and certain components and certain medium trace elements generate coagulation reaction, so that the effectiveness of nutrients of the fertilizer is reduced. The medium and trace elements applied to the soil in the form of medium and trace element metal salts are not only quickly fixed and lost by the soil, but also some medium and trace elements are not easily absorbed by crops or even can not be absorbed (such as iron ions). According to literature reports, after being chelated, the medium trace elements can be obviously improved by 2-5 times, and the utilization rate of the fertilizer can be higher when the fertilizer is used with a large-amount element nitrogen, phosphorus and potassium formula according to the fertilizer requirement rule of crops and the fertilizer supply capacity of soil. At present, the chemical chelating agent is mainly used for chelating with trace elements at home, is not easy to degrade and remains in soil. Therefore, the research on the on-line chelating of trace elements by a chelating agent produced by a biological fermentation process is pollution-free/biodegradable, the process is a green ecological chelating fertilizer production process, and the biochemical chelating fertilizer which can obviously improve the fertilizer utilization rate and is safe and environment-friendly is one of important measures for improving the quality and the efficiency of agriculture and reducing the non-point source pollution of agriculture.
Disclosure of Invention
The invention aims to provide a biochemical chelate fertilizer and a manufacturing method thereof. According to the invention, the bacillus natto is fermented under a specific fermentation process to generate the chelating agent polyglutamic acid, trace elements are slowly added into a reaction system in the fermentation process, the following chelation is realized, the formed polyamino acid chelate is biodegradable along with the generation, the chelating capacity is strong, the polyamino acid chelate is not easily fixed by soil, is more easily absorbed by crops, the fertilizer utilization rate is higher, the fertilizer is not easily lost, the environmental pollution is reduced, and the bacillus natto-containing fertilizer is an environment-friendly novel fertilizer.
