Problems solved by technology

The shortcomings of organic fertilizers are that there are few types of nutrient elements, uncoordinated nutrient ratios, limited effects and functions, and cannot meet the needs of crop growth and development.
These products still have disadvantages: high production cost, complicated process, which can cause secondary pollution; few nutrients in fertilizer, unable to fully supply the nutrients needed for crop growth and development, so the potential for increasing production is limited

Abstract

The invention relates to an organic mineral fertilizer (rare earth-silicon-calcium-magnesium fertilizer), which is prepared from medical stone, phosphorous slag containing rich lanthanum rear earth, silicon, calcium and magnesium, organic matters and humic acid. Besides the components of conventional organic fertilizers, the organic mineral fertilizer also contains scores of nutritive elements needed by crops for growth and development such as silicon, calcium, magnesium, iron, copper, manganese, zinc, molybdenum, boron, selenium, titanium, sodium, vanadium, nickel, iodine, aluminum, chromiumand phosphorus. The elements have complementary advantages and respective functions. The organic mineral fertilizer mainly has the functions of increasing organic matter content, promoting the decomposition of organic matter, activating solid phosphorus in soil, modifying soil, relieving soil hardening, degrading residual pesticides and harmful materials in soil, balancing the acidity and basicity of the soil, purifying soil environment, improving the resistance of plants to natural disasters, improving fertilizer utilization rate and validity period and improving quality of agricultural products.

Description

technical field [0001] The invention relates to an organic mineral fertilizer (rare earth silicon calcium magnesium fertilizer) suitable for crops. Background technique [0002] Due to long-term excessive or unreasonable use of chemical fertilizers, the proportion of nutrients in the soil is imbalanced, the atmosphere, soil and groundwater are polluted, the organic matter content in the soil decreases, the compaction intensifies, the quality of agricultural products decreases, and the agricultural ecological environment deteriorates. [0003] At present, there are many types of organic fertilizers on the market, mainly organic matter, amino acids, humic acids or a combination of several types of fertilizers, and some varieties also add a small amount of chemical fertilizers. The advantages of organic fertilizers are that they can increase the organic matter content in the soil, increase the soil aggregate structure, improve soil physical and chemical properties, and relieve ...
