Abstract

The invention discloses a selenium-rich ecological water-soluble fertilizer and a preparation method thereof and belongs to the field of fertilizer. The fertilizer is prepared from, by weight, 20-30 parts of urea, 10-15 parts of mono potassium phosphate, 3-6 parts of urea phosphate, 3-8 parts of calcium superphosphate, 3-8 parts of zinc sulfate, 5-10 parts of magnesium sulfate, 1-3 parts of manganese sulfate, 1-3 parts of sodium selenite, 0.5-1 part of a microbial agent, 0.5-1 part of an accelerant and 1-3 parts of modified silica gel. The fertilizer can provide rich nutrient elements for crops, particularly the selenium element; meanwhile, by adding a gel substance, heavy metal elements in the soil can be effectively adsorbed and immobilized, the absorption of the crops for the heavy elements is reduced, the crop quality is improved, and the crop yield is increased.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a selenium-enriched ecological water-soluble fertilizer and a preparation method thereof. Background technique [0002] Our country's soil is facing the threat of serious pollution. The excessive use of chemical fertilizers and pesticides has led to the decline of soil fertility and serious environmental pollution, which not only endangers the safety of food crops, but also seriously damages the ecology. The data show that the amount of chemical fertilizers used in my country ranks first in the world. Excessive use of chemical fertilizers has led to a decline in the quality of ecological elements in agricultural production. In many areas, the content of organic matter in farmland has dropped from 50-70% before liberation to 1%. The amount of pesticides used in my country has reached 1.3 million tons, which is 2.5 of the world's average level, but the actual utili...
