Description
Technical Field
The invention relates to the field of compound fertilizers, in particular to a boron-magnesium fertilizer and a preparation method thereof.
Background
Magnesium plays an important role in the growth and development process of animals and plants. Magnesium is a cofactor for many enzymes such as atpase, an important substance for stabilizing cell membranes, an essential element for maintaining the structural integrity of many proteins in the body, and an important intracellular signaling molecule.
For humans, inadequate magnesium intake can lead to a number of physical problems, such as angina, adrenal fatigue, anxiety, arteriosclerosis and calcium deposits, asthma, hypertension, arthritis, and the like. The magnesium nutrition required by human body every day is mostly needed to be supplemented from diet, namely from animals and plants. Among them, magnesium is taken in from plants in a very large proportion.
Magnesium is a constituent of plant chlorophyll, is also essential for many enzymes, and can enhance photosynthesis, promote growth, promote fruit sugar accumulation, and the like. In plants lacking magnesium, a number of problems arise, such as: green leaves, reduced photosynthesis, hindered growth, reduced disease resistance and stress resistance, less sugar accumulation, slow fruit color change, etc. In long-term planting activities, very much magnesium has been removed from the soil, but little magnesium is supplemented to the soil every year. According to the investigation of authorities, the magnesium deficiency of 53 percent of soil in China is serious. Therefore, it is of great significance to supplement sufficient magnesium element to the soil in time to complement the needs of plant growth.
The potassium and magnesium containing ore or slurry is usually granulated or evaporated and crystallized to obtain the product. In patent cn201210323130.x potash magnesium sulphate fertilizer and its preparation method, a preparation method of potash magnesium sulphate fertilizer is provided: crushing and mixing the potassium magnesium sulfate, the clay and the trace elements according to a proportion, adding water, and obtaining the potassium magnesium sulfate fertilizer through extrusion, drying and cooling. In patent CN200810232285.6 "method for extracting potash magnesium sulphate fertilizer by separation of solid ore containing potassium", a preparation method of potash magnesium sulphate fertilizer is provided: the potassium-containing sulfate mine and magnesium chloride saturated brine obtained by solarization and evaporation of salt lake brine and a salt pan are used as raw materials, potassium in the salt mine is leached by salting out of magnesium chloride brine to obtain a potassium saturated solution, the potassium saturated solution is added into the salt pan to be evaporated to obtain a low-sodium magnesium sulfate and carnallite mixed ore, and the potassium sulfate magnesium fertilizer is obtained by decomposition and conversion.
The product obtained by the technology has high content of most potassium and low content of magnesium element, and cannot meet the requirement of crops on magnesium. And most products obtained by the technology can not reach full water solubility and can not be used in water and fertilizer integrated facilities.
Disclosure of Invention
Aiming at the problems, the invention provides a boron-magnesium fertilizer which comprises the following components in parts by weight: 90-95 parts of magnesium sulfate heptahydrate, 1-2 parts of urea, 4-8 parts of boric acid and 1-5 parts of zinc phosphite.
