[0036] 1) crush the weathered coal to 120 mesh;

[0037] 2) 1 kg of weathered coal, 20 kg of water, and 200 g of composite flora are added to the reactor; wherein, the composite flora is a mixture of Trichoderma, Bacillus megaterium and Bacillus subtilis, and the mixing ratio is 1:1.5:0.5 by weight; Stir evenly at a stirring rate of 150r / min, add 200g of 0.3% sodium hydroxide aqueous solution and continue stirring; then add 10g of mixed amino acid salt and 20g of EDTA-zinc and stir for 0.5h; the mixed amino acid salt is sodium glycinate, sodium tyrosine and The mixing of sodium tryptophanate, the mixing ratio is 1:0.5:0.2 by weight;

[0038] 3) Filter the above mixture for 2 times. The filter adopts a CT barrel plate and frame filter produced by Haining Zhengxing Special Filter Equipment Manufacturing Co., Ltd., and then heat the supernatant to 120° C. for 3 hours, and concentrate until the solid content is 30%.

Embodiment 3

[0040] 1) crush the weathered coal to 150 mesh;

[0041] 2) 1 kg of weathered coal, 20 kg of water, and 200 g of composite flora are added to the reactor; wherein, the composite flora is a mixture of Trichoderma, Bacillus megaterium and Bacillus subtilis, and the mixing ratio is 1:1.5:1 by weight; Stir evenly at a stirring rate of 200r / min, add 500g of 0.3% sodium hydroxide aqueous solution and continue stirring; then add 10g of mixed amino acid salt and 20g of EDTA-zinc and stir for 0.5h; the mixed amino acid salt is sodium glycinate, sodium tyrosine and The mixing of sodium glutamine, the mixing ratio is 1:0.6:0.3 by weight;

[0042] 3) Centrifuge the above mixture. The centrifugal separation adopts the PQSB flat-panel full flip centrifuge produced by Zhangjiagang Leyu Electromechanical Equipment Factory, and then heat the supernatant to 120° C. for 4 hours, and concentrate to a solid content of 60%. .

Abstract

The invention provides a composite fertilizer synergist and a preparation method thereof. The synergist contains 15-18% of humic acid, 0.01-0.02% of zinc and 0.02-0.03% of boron, the pH of the synergist is 9-11, the ammonia volatilization inhibition rate is 10% or above, and the phosphorus fixation rate is reduced by at least 15%. The synergist can stimulate crop root meristems, increase secondary roots and improve nutrient absorption capacity. Vigorous growth of vegetative mass on the ground is promoted, and the biological yield is increased. Meanwhile, the synergist has the functions of improving soil, enhancing fertilizer efficiency, regulating crop growth, improving crop stress resistance, improving crop quality, increasing crop yield and the like, and also has the functions of supplementing and activating soil trace elements and the like.

Description

technical field [0001] The invention relates to a compound fertilizer synergist and a preparation method thereof, belonging to the technical field of chemical fertilizer synergists. Background technique [0002] The application of chemical fertilizers is an important measure to ensure high and stable grain production. In this century, 1 / 2 of the world's grain production per unit area and 1 / 3 of the total output come from the contribution of chemical fertilizers. If chemical fertilizers were stopped, global crop yields would drop by 50%. The contribution rate of chemical fertilizers to my country's grain production is as high as 40% to 60%. It is self-evident that chemical fertilizers play an important role in food security. At the same time, there have been problems such as irrational use of chemical fertilizers and unbalanced nutrients in my country for many years, which not only caused low nutrient utilization, waste of resources, increased agricultural input costs, and ...
