Problems solved by technology

At present, there have been some reports on fungi, bacteria, and actinomycetes that can promote the growth of economic crops such as bananas, but many studies have shown that a single application of a certain strain can rarely achieve a good growth-promoting effect; in addition, these growth-promoting bacteria need Add soil to a suitable carrier. Without a suitable carrier, it is difficult to survive after adding the soil, resulting in poor results

Embodiment 1

[0020] Preparation of bacterial solution

[0021] Taking the rhizosphere soil of the banana garden as the research object, Bacillus jelly jelly and Rosemonospora obtained after isolation and purification were screened. After activation, one ring of activated colonies was picked respectively, and inoculated into 1L LB culture medium at 30°C. In a constant temperature shaking incubator, culture at 130 rpm for 24 hours to form a bacterial liquid.

[0022] Prepare several Erlenmeyer flasks with a capacity of 500mL, pour 200mL of PDA (pH value adjusted to 7.0) culture solution into the 500mL Erlenmeyer flasks, and carry out high-temperature sterilization after sub-packaging, and set aside.

[0023] The two cultured bacterial solutions were inoculated into a 500mL Erlenmeyer flask containing 200mL of PDA culture solution according to the volume ratio of the bacterial solution and the culture solution at a ratio of 1:100, and then cultivated at 33°C for 48h at a shaker speed of 100rp...

Embodiment 2

[0025] 1. Preparation of bio-organic fertilizer 1

[0026] (1) Raw material preparation: first mix the raw material molasses fermentation liquid and pumice, and then mix with the raw material cow dung, traditional Chinese medicine slag, crushed fruit peel, potassium ore powder, and phosphate rock powder;

[0027] The mass ratio of dry matter mixed with cow dung, traditional Chinese medicine residue, peel crushed material, potassium ore powder, phosphate rock powder, molasses fermentation liquid and pumice is 55:20:30:20:6:7.5:15;

[0028] The traditional Chinese medicine dregs are composed of herbaceous root dregs, pyrethrum dregs, eucalyptus dregs and Luoxing herbal dregs; the composition dry matter mass ratio is 1:1~1.3:1.5~2:0.8~1.0;

[0029] Pumice is granular solid, 0.01cm<particle size≤0.5cm;

[0030] The solid matter content of the molasses fermented liquid is 50%-60%.

[0031] (2) Primary fermentation: After the above-mentioned materials are mixed evenly, add 1% to 3...

Embodiment 3

[0074] field test

[0075] 1. Materials and methods

[0076] The tested banana variety was Brazilian banana.

[0077] Bio-organic fertilizers for testing: sample bio-organic fertilizer 1, bio-organic fertilizer 2, bio-organic fertilizer 3, bio-organic fertilizer 4, bio-organic fertilizer 5, organic fertilizer 6 and conventional fertilizer for testing.

[0078] Test site: Lvxin Banana Planting Base, Luoxu Town, Wuming District, Nanning City. Seven treatments were set up in the test area, with 10 rows for each treatment and 20 plants in each row. A total of 200 plants were planted with a row spacing of 2m×2.5m. Fertilization was applied for the first time on March 27, 2017 in the test area, and for the second time on August 2.

[0079] 2. Experimental design

[0080] The experimental design consists of 7 treatments, namely:

[0081] Treatment 1: sample bio-organic fertilizer 1 (fertilization twice), hereinafter referred to as F1.

[0082] Treatment 2: sample bio-organic fer...

Abstract

The invention relates to the technical field of agricultural soil fertilizers, and particularly discloses a cow dung bio-organic fertilizer as well as a preparation method and application thereof. Thecow dung bio-organic fertilizer is prepared by the following method: mixing cow dung, traditional Chinese medicine residues, pericarp, potassium ore powder, phosphate ore powder, molasses fermentation liquor and pumice according to a dry matter mass ratio of (50-55): (20-25): (20-30): (15-20): (4-6): (7.5-10): (10-15), and composting and fermenting to prepare a semi-finished organic fertilizer; inoculating the semi-finished organic fertilizer with a composite bacterial agent composed of Bacillus mucilaginosus and Micromonospora roseopurpurea; and preparing the cow dung bio-organic fertilizerthrough secondary fermentation. The high-quality bio-organic fertilizer disclosed by the invention can improve banana growth soil, promote nutrient utilization rate and increase banana yield.

Description

technical field [0001] The invention belongs to the technical field of agricultural soil fertilizers, in particular to a cow dung bio-organic fertilizer and its preparation method and application. Background technique [0002] Organic fertilizers have complete nutritional elements. Reasonable application of organic fertilizers can not only reduce the discharge of pollutants such as livestock and poultry manure, the random discarding and stacking of wastes such as medicinal residues and fruit peels, reduce the use of chemical fertilizers, but also improve the quality of agricultural products and promote organic food production. production and increase farmers' income. Therefore, the development of the organic fertilizer industry is in line with the national agricultural development orientation and is of great significance to environmental protection and sustainable agricultural development. At the same time, adding growth-promoting microorganisms to organic fertilizers can h...
