Problems solved by technology

my country's fertilizer output and usage are the first in the world, but there are many problems in the use of fertilizers in my country: (1) The utilization rate of fertilizers is low, and the loss of fertilizers causes serious environmental pollution
Due to the excessive application of chemical fertilizers or the low utilization rate of fertilizers, soil water-soluble nutrients and other substances are leached into groundwater and rivers by rainwater and farmland irrigation, causing groundwater and river pollution in some areas, making groundwater, rivers and lakes rich. Nutritization makes the groundwater unhealthy, and fish and shrimp in some rivers and lakes often die
(2) Single or partial application of chemical fertilizers will cause serious damage to farmland soil nutrients, etc.
At present, there are few cases of applying slow-release magnetized compound fertilizers to wheat production

Abstract

A slow-release magnetized compound fertilizer specially used for wheat and a preparation method of same. The fertilizer is prepared from, by weight, 20-30 parts of urea, 4-10 parts of calcium superphosphate, 12-18 parts of potassium chloride, 3-5 parts of a humic fertilizer, 0.5-1 part of ammonium molybdate, 0.5-1 part of manganese sulfate, 2-3 parts of plant ash, 6-10 parts of a fertilizer additive, and 32-40 parts of a magnetic carrier. Iron-beneficiating tailing sand is compounded with the fertilizer to perform magnetizing treatment, so that the fertilizer can increase productivity and yield, improves soil environment, can retain nutrients and prevent nutrient loss, is greatly improved in utilization rate, comprehensively utilizes resources, is low in emission of water liquid, waste solid and waste gas, and has good environmental benefit.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a special slow-release magnetized compound fertilizer for wheat and a preparation method thereof. Background technique [0002] my country is the most populous country in the world, and it is also a big agricultural country. Grain production occupies an important position in agricultural production. The main way to increase the grain output per unit area is to use chemical fertilizers in agricultural production. my country's fertilizer production and usage are the first in the world, but there are many problems in the use of fertilizers in my country: (1) The utilization rate of fertilizers is low, and the loss of fertilizers causes serious environmental pollution. Although my country invests a large amount of fertilizers in agricultural production every year, the utilization rate of fertilizers is far behind that of developed countries. Compared with the 55% fertil...
