Embodiment 1

[0024] Acquisition of bacterial fluid

[0025] After isolation and purification from the soil, Lactobacillus crispatus and Bacillus cohesin were obtained by screening. After activation, the activated colonies were picked respectively, inserted into 1L LB culture medium, placed in a constant temperature shaking incubator at 30°C, and cultivated at 200rpm for 24 hours. bacteria liquid.

[0026] Place the obtained bacterial liquid in the fermenter and cultivate it in the PDA culture medium, so that the target bacterial strain in the fermenter reaches 1×10 8 ~1×10 9 cfu / ml.

[0027] The two cultured strains were mixed according to the colony forming unit number ratio of 1: (0.8~1) to obtain a composite bacterial liquid.

Embodiment 2

[0029] 1. Preparation of Liquid Bioorganic Fertilizer 2

[0030] (1) Preparation of decomposed compost products

[0031] Using 60 parts of pig manure, 30 parts of medicinal dregs and 25 parts of fruit peel as raw materials, the decomposed compost product was obtained by composting and fermenting for 7 days after inoculating yeast.

[0032] The medicinal residues are a mixture of medicinal residues from Dacha root and yellow sunflower, and the mass ratio is 1:1.

[0033] The peel is banana peel.

[0034] The yeast inoculum was 1×10 5 cfu / g.

[0035] (2) Mix the decomposed compost product with water, the mixing ratio is 1:12, and filter through a 100-mesh sieve to obtain the decomposed compost filtrate;

[0036] (3) Mix the decomposed compost filtrate with the molasses fermentation liquid, and inoculate the microbial complex bacterial liquid, and the inoculum amount of the complex bacterial liquid is 1×10 5 cfu / ml;

[0037] The solid content of the molasses fermentation li...

Embodiment 3

[0046] 1. Preparation of Liquid Bioorganic Fertilizer 3

[0047] (1) Preparation of decomposed compost products

[0048] Using 50 parts of cow manure, 40 parts of medicinal dregs and 20 parts of fruit peel as raw materials, the decomposed compost product was obtained by composting and fermenting for 5 days after inoculating yeast.

[0049] The medicinal residues are a mixture of medicinal residues from Dacha root and yellow sunflower, and the mass ratio is 1:1.2.

[0050] The peel is orange peel and grapefruit peel.

[0051] The yeast inoculum was 1×10 5 cfu / g.

[0052] (2) Mix the decomposed compost product with water at a mixing ratio of 1:15, and filter through a 100-mesh sieve to obtain the decomposed compost filtrate;

[0053] (3) Mix the decomposed compost filtrate with the molasses fermentation liquid, and inoculate the microbial complex bacterial liquid, and the inoculum amount of the complex bacterial liquid is 1×10 5 cfu / ml;

[0054] The solid content of the mo...

Abstract

The invention relates to the technical field of agricultural soil bio-fertilizers, and particularly discloses a liquid bio-organic fertilizer for preventing root rot as well as a preparation method and application thereof. The liquid bio-organic fertilizer is prepared by mixing molasses fermentation liquor in thoroughly decomposed compost product filtrate, then inoculating a compound bacteria solution consisting of lactobacillus crispatus and ensifer adhericida, and carrying out aerobic fermentation. The liquid bio-organic fertilizer provided by the invention realizes good prevention and control of crop root rot, reduces pollution of pesticides to the ecological environment, has an obvious soil improvement effect and a good crop growth promotion effect, and can obviously improve the crop yield.

Description

technical field [0001] The invention belongs to the technical field of agricultural soil bio-fertilizer, in particular to a liquid bio-organic fertilizer for preventing root rot and its preparation method and application. Background technique [0002] Agricultural crop production provides an important guarantee for people's basic living materials. In agricultural production, in order to ensure that crops can go on the market smoothly and improve the economic return of crops, farmers often need to use a large amount of chemical fertilizers and chemical pesticides to promote crop growth and prevent pests and diseases. to ensure crop yields. The long-term and frequent use of these substances has brought new problems to agriculture: first, the long-term use of chemical fertilizers has caused serious imbalances in plant nutrients, soil compaction and aging; second, long-term use of chemical pesticides has greatly increased the cost of planting , Residual chemical pesticides brin...
