Problems solved by technology

[0003] In the current production, the soil generally lacks organic matter, and the physical and chemical properties of the soil continue to deteriorate. In the process of applying microbial fertilizers, the strains lose the basic conditions for reproduction due to the deterioration of the living environment, showing that the microbial fertilizer efficiency cannot play a role
These factors may cause the effect of microbial fertilizers to be unstable, and even cause losses to agricultural production.

Embodiment 1

[0025] From August 10, 2018 to June 10, 2019, the 10-year-old 'Cuiguan' pear under conventional planting conditions was used as the test material. The preparation of the present invention is homopolyamino acid (γ-polyglutamic acid) 50%, free amino acid (glutamic acid, glycine, aspartic acid, proline, valine, alanine) 28%, betaine 5% %, trehalose 8%, malic acid 4%, diatomaceous earth 5%. 8% added amount was mixed with microbial fertilizer, and 6 plants were treated with 3 repetitions. Pure microbial fertilizer (Bacillus ≥ 200 million / g) and blank (no bacterial fertilizer) were used as controls. Experimental results show that the preparation of the present invention cooperates with the microbial fertilizer to significantly improve the number of beneficial microorganisms in the rhizosphere soil.

Embodiment 2

[0033] From August 10, 2018 to June 10, 2019, the 10-year-old 'Cuiguan' pear under conventional planting conditions was used as the test material. The preparation of the present invention is homopolyamino acid (γ-polyglutamic acid) 40%, free amino acid (glutamic acid, glycine, aspartic acid, proline, valine, alanine) 30%, betaine 10% %, trehalose 10%, malic acid 5%, diatomaceous earth 5%. Mix and apply with 8% addition amount and microbial fertilizer, each treatment 6 plants, repeat 3 times. Take pure microbial fertilizer (bacillus ≥ 200 million / g) and blank (no bacterial fertilizer) as controls. The experimental results show that the preparation of the present invention cooperates with the microbial fertilizer to significantly improve the number of beneficial microorganisms in the rhizosphere soil.

Embodiment 3

[0041]From August 10, 2018 to April 8, 2019, under the conditions of greenhouse planting, watermelon seedlings inoculated with Fusarium wilt in nutrient bowls were used as test materials to study the degree of antagonistic disease. The preparation of the present invention is homopolyamino acid (γ-polyglutamic acid) 50%, free amino acid (glutamic acid, glycine, aspartic acid, proline, valine, alanine) 25%, betaine 8 %, trehalose 8%, malic acid 4%, diatomaceous earth 5%. Mix and apply 10% addition amount with microbial fertilizer, 10 plants in each plot, repeat 3 times. Commercially available compound microbial fertilizer (effective viable bacteria ≥ 200 million / g) and blank (no bacterial fertilizer) were used as controls. The experimental results show that the preparation of the present invention significantly improves the effect of microbial bacterial fertilizer to improve resistance to Fusarium wilt, and improves yield.

Abstract

The invention relates to the technical field of fertilizers, in particular to a microbial fertilizer synergistic preparation and a preparation method thereof. The microbial fertilizer synergistic preparation comprises 40-50% of homopolymerized amino acid, 25-30% of free amino acid, 5-10% of glycine betaine, 5-10% of trehalose, 1-5% of an organic acid and 1-5% of an auxiliary agent. When microbialfertilizer is applied in the growth period of fruit tree crops, the microbial fertilizer synergistic preparation (the dosage is 5-10% of the mass of the microbial fertilizer) is added in a mixed mode,the colonization efficiency and survival rate of functional strains in plant rhizosphere and soil after the microbial fertilizer is applied can be remarkably improved, rapid propagation of the functional strains is promoted, and the fertilizer action effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a microbial fertilizer synergistic preparation and a preparation method thereof. Background technique [0002] Microbial fertilizers (microbial agents, bio-organic fertilizers and compound microbial fertilizers) are key products for the development of the national bio-industry. At the national macro level, "weight loss and drug reduction", "zero growth of chemical fertilizers", "sustainable agricultural development" and "ecological agriculture" development It will play an active role in the process and has broad application prospects. Microbial fertilizer As a living fertilizer, functional strains need to be colonized and multiplied in the soil before they can function. [0003] In the current production, the soil generally lacks organic matter, and soil physical and chemical properties continue to deteriorate. In the process of applying microbial fertilizers, the strains lo...
