Liquid compound fertilizer

Abstract

The invention discloses a liquid compound fertilizer. The liquid compound fertilizer is prepared from the following raw materials in parts by mass: 0.1-0.5 part of glycine, 10-50 parts of glycerin, 30-45 parts of wheat malt slurry, 20-25 parts of corn oil, 10-25 parts of diammonium hydrogen phosphate, 10-50 parts of maifanite powder and 10-35 parts of a microbial liquid; and the bacterial liquid is prepared by mixing of a bacillus megaterium bacterium liquid obtained by fermentation of bacillus megaterium, a bacillus subtilis bacterium liquid obtained by fermentation of bacillus subtilis, a bacillus licheniformis bacterium liquid obtained by fermentation of bacillus licheniformis, a bacillus mucilaginosus bacterium liquid obtained by fermentation of bacillus mucilaginosus, and a streptomyces Jingyangensis bacterium liquid obtained by fermentation of streptomyces Jingyangensis according to a mass ratio of (1-4):(1-3):(1-2):(2-6):(1-2). The liquid compound fertilizer provided by the invention has a reasonable formula, and diversified and long-lasting fertilizer effects; because the wheat malt slurry and the maifanite powder are added, absorption of the chemical fertilizer by crops can be improved, and meanwhile soil hardening conditions caused by the fertilizer can be avoided; and the beneficial microorganisms are added, and therefore the fertilizer has good effects of nitrogen fixation and phosphate solubilization, germ resistance, and the ability of enhancing soil fertility and stimulating crop growth.

Description

technical field [0001] The invention relates to the field of chemical fertilizers, in particular to a liquid compound fertilizer. Background technique [0002] Chemical fertilizers have the characteristics of high nutrient and rapid fertilizer efficiency, and are widely used in agricultural production, becoming an indispensable substance to increase crop yield. [0003] Existing liquid chemical fertilizers have the following deficiencies: low fertilizer utilization rate; nitrogen is extremely volatile; fertilizer rate is released quickly, and crops do not have enough time to absorb and utilize; it is greatly affected by natural conditions, such as fertilization when there is drought, little rain and no irrigation conditions. Then the fertilizer effect will be difficult to bring into play. When the soil moisture content is too high, fertilization will easily produce leaching and cause waste and environmental pollution. If the amount of fertilizer applied is too low and canno...

[0003] Existing liquid chemical fertilizers have the following deficiencies: low fertilizer utilization rate; nitrogen is extremely volatile; fertilizer rate is released quickly, and crops do not have enough time to absorb and utilize; it is greatly affected by natural conditions, such as fertilization when there is drought, little rain and no irrigation conditions. Then the fertilizer effect will be difficult to bring into play. When the soil moisture content is too high, fertilization will easily produce leaching and cause waste and environmental pollution. If the amount of fertilizer applied is too low and cannot meet the needs of the entire growth period of the crops, topdressing in stages will not only cost a lot of labor and financial resources, but also many chemical fertilizers are not suitable for topdressing, so the expected effect cannot be achieved
