Problems solved by technology

Too many harmful microorganisms will crowd out the living space of beneficial microorganisms, and the beneficial microorganisms will gradually decrease, which will make the roots of crops prone to diseases, restrict the growth of crops and even cause sudden death

preparation example Construction

[0034] Wherein, the preparation method of described bacillus subtilis and bacillus amyloliquefaciens inoculum comprises the following steps:

[0035] (1) Strain activation: Inoculate the low-temperature-preserved Bacillus subtilis and Bacillus amyloliquefaciens strains on the plate medium respectively, and culture them at 28-39°C for 24-26 hours; then pick a single colony and inoculate them on the slant medium and cultured at 30-39°C for 24-26 hours, then washed the surface of the medium with sterile water, and the eluate was used as the inoculum;

[0036] (2) Preparation of seed solution: add the inoculation solution prepared in step (1) into the liquid medium according to the volume percentage of 1-10%, shake and cultivate at 26-36° C. for 12-18 hours to obtain the seed solution;

[0037](3) Fermentation culture: the seed solution obtained in step (2) is inserted into the corn flour bean cake powder medium according to the volume percentage of 3-10%, and the temperature is 2...

Embodiment 1

[0039] A method for improving soil through the joint action of mixed bacterial agents and chemical fertilizers, comprising the steps of:

[0040] Step 1: Put the corn stalks into the pulverizer for crushing, crush the corn stalks to a length of less than 5 cm, then thermally crack the corn stalks at 500°C under anaerobic conditions, and continue the thermal cracking for 3 hours , prepared into biochar after natural cooling;

[0041] Step 2: Apply the mixed bacterial agent to the soil at a rate of 200 kg / mu evenly 30 days before the farmland is cultivated, and fully mix the soil in the plow layer with the mixed bacterial agent. The mixed bacterial agent is composed of the following components: 1500 The biochar of weight part and the composite microbial bacterial agent of 10 weight parts, described composite microbial bacterial agent is made up of Bacillus subtilis, Bacillus licheniformis, Bacillus lateral sporosum, Bacillus megaterium, Bacillus amyloliquefaciens, Trichoderma ha...

Abstract

The invention belongs to the field of farmland soil improvement, and particularly relates to a method for improving soil through the combined action of a mixed fungicide and a chemical fertilizer. The method comprises the following steps: crushing corn straws in a crusher, carrying out thermal cracking on the corn straws, and naturally cooling to prepare charcoal; uniformly applying the mixed bacterial agent into farmland soil according to the proportion of 200kg / mu; when the base fertilizer is applied during farmland cultivation, the application amount of the chemical fertilizer is 30%-50% of the conventional application amount, the application amount of the normal sorghum per mu is 30 kilograms, and the application amount of the compound fertilizer per mu is 9-15 kilograms. The method disclosed by the invention is simple and easy to implement, and needs to supplement a mixed microbial agent once every year, which relieves farmland soil hardening and acidification, improves farmland soil fertility, reduces soil bulk density, promotes farmland soil organic matter accumulation, is beneficial to growth of farmland soil microbial flora, improves crop rhizosphere environment, reduces farmland chemical fertilizer consumption, reduces crop diseases and insect pests, and improves the fertilizer utilization rate.

Description

technical field [0001] The invention relates to the technical field of agricultural waste recycling and farmland soil improvement in the environmental protection of agricultural resources, in particular to a method for improving soil through the joint action of mixed bacterial agents and chemical fertilizers. Background technique [0002] Soil acidification refers to the process of leaching and loss of calcium, magnesium and other basic ions in the soil after being replaced by exchangeable hydrogen and aluminum ions. It is mainly manifested in the dispersion of soil particles and the destruction of the water-stable aggregate structure of the soil; Changes in the mineralization environmental conditions of the soil, especially the aggravation of the mineralization release ratio of various elements in the soil, eventually lead to soil compaction, and a sharp decline in crop yield and quality. [0003] Soil compaction means that the soil has poor permeability and low oxygen cont...
