Problems solved by technology

[0002] Corn is an important economic crop in my country, and the input of fertilizer plays a vital role in the yield of corn. However, in the actual planting process of corn, there have been problems of single and excessive fertilization for a long time, and the average utilization of fertilizer The rate is very low, the main reason is that the fertilizer is quick-acting and volatile and easy to lose
The corresponding measures are to use slow-release coated fertilizers to improve the utilization rate of nutrients, but the strength of the single-layer coating is low, the proportion of slow-release nutrients is fixed, and it is not targeted, and does not meet the constraints of crops' nutrient requirements in different periods. own development

Abstract

The invention discloses green and environment friendly slow-release fertilizer synergist used for corn. The fertilizer synergist comprises, by weight, 1-2 parts of borax, 14-16 parts of potassium humate, 1-2 parts of aluminium potassium sulfate, 6-8 parts of sea-foam stone powder, 23-25 parts of peanut shell coarse powder, 27-29 parts of furfural residue, 8-10 parts of charcoal, 2-4 parts of slow-release microbial zones, 4-5 parts of slow-release microelement chelation layers, 6-9 parts of slow-release sitallization powdered rock phosphate coating layers and a defined amount of water. According to the fertilizer synergist used for the corn, the release rate of effective constituents is consistent with that of fertilizer requirement laws of the corn, meanwhile, the content of absorbable nutrients in the soil is increased, the effective nutrient utilization rate of combined application fertilizer is improved, the randomness and blindness of fertilization are overcome, the waste of fertilizer is reduced, the production cost is reduced, and a path for developing green corn plantation industry and protecting ecological environment is provided.

Description

technical field [0001] The invention relates to the technical field of fertilizer synergists, in particular to a green and environmentally friendly slow-release fertilizer synergist for corn and a preparation method thereof. Background technique [0002] Corn is an important economic crop in my country, and the input of fertilizer plays a vital role in the yield of corn. However, in the actual planting process of corn, there have been problems of single and excessive fertilization for a long time, and the average utilization of fertilizer The rate is very low, the main reason is that the fertilizer is quick-acting and volatile and easy to lose. The corresponding measures are to use slow-release coated fertilizers to improve the utilization rate of nutrients, but the strength of the single-layer coating is low, the proportion of slow-release nutrients is fixed, and it is not targeted, and does not meet the constraints of crops' nutrient requirements in different periods. own ...
