Efficient fertilizer helpful for raising nitrogen utilization rate of spinach and preparation method thereof

Abstract

The invention discloses an efficient fertilizer helpful for raising nitrogen utilization rate of spinach. The efficient fertilizer comprises the following ingredients: melatonin, a water-soluble silicon fertilizer, humic acid, mannoproteins, yeast, soybean curb residue, alga residue, high temperature calcined oyster shell porous powder, nanometer black bone charcoal, oxidized sodium alginate, a proper amount of mineralized small molecular activated water, etc. By using melatonin, the water-soluble silicon fertilizer, mineralized small molecular activated water and nanometer black bone charcoal, a nitrogen utilization promoter is prepared. Small molecular water-soluble silicon powder participates in cell metabolism to promote synthesis of an amino acid substance from a nitrogen substance. Melatonin accelerates photosynthesis and metabolism of plants and promotes utilization of nitrogen and oxalic acid. Thus, enrichment of nitrogen and oxalic acid by spinach is minimized and efficient cultivation of spinach is realized. Meanwhile, in cooperation with a nutrient solution processed with mineralized small molecular activated water and main materials, the fertilizer of the invention has rich nutrients and can effectively minimize enrichment of nitrogen and oxalic acid in spinach and raise quality of spinach.

Description

technical field [0001] The invention relates to the technical field of vegetable fertilizers, in particular to a high-efficiency fertilizer that helps improve the nitrogen utilization rate of spinach and a preparation method thereof. Background technique [0002] Spinach is an important vegetable, and it is widely loved by the public because of its rich nutrition and delicious flavor. However, spinach can accumulate high amounts of nitrate, and it is also an oxalic acid accumulating vegetable. Excessive intake of NO3- by the human body can be reduced to NO2-, which can lead to methemoglobinemia, or combine with secondary amines to form strong carcinogens, and trigger the human digestive system. Oxalic acid is a toxin and anti-nutritional factor in vegetables. Long-term intake of human body will cause trace amounts of Deficiency of elements can lead to disease. Contents of the invention [0003] The object of the invention is to make up for the defects of the prior art, an...
