Problems solved by technology

[0005] Although microbial preparations play a certain role in soil improvement, the survival and reproduction of microorganisms have relatively high environmental requirements, and their mortality rate is high in the actual application process, so they cannot play a good role in soil improvement; in addition, microorganisms are not the source of plant growth. Nutrient elements, in different environments, the role of microorganisms is unstable, so the same microbial agent will appear, which has different effects in different regions, and cannot stably meet the nutritional needs of crops during the growth process

Embodiment 1

[0039] 1. Preparation of microbial agents

[0040] Bacillus subtilis, Bacillus jelly-like, Bacillus megaterium and Bacillus thuringiensis are respectively activated, and after activation, they are respectively inoculated into respective strain culture media to obtain the strain culture liquid of each Bacillus.

[0041] After expanding the culture medium of each Bacillus strain, inoculate them into their respective main fermentation tanks, and cultivate them at a temperature of 35-37°C, a pH value of 7.0-7.5, and a stirring rate of about 150r / min , Cultivate about 8-10h to reach the logarithmic growth phase, then add about 0.1ppm of micro-nano silicon (particle size is 100 nanometers-10 microns) to the fermentation broth of each bacillus, continue to cultivate about 30min, and then add each spore About 0.1 ppm of nano-carbon (with a particle size of 5-150 nanometers) was added to the fermentation liquid of the bacillus, and the culture was continued for about 20 hours to obtain...

Embodiment 2

[0051] 1. Preparation of microbial agents

[0052] Bacillus subtilis, Bacillus jelly-like, Bacillus licheniformis and Bacillus thuringiensis are respectively activated, and after activation, they are respectively inoculated into respective strain culture medium to obtain the strain culture liquid of each Bacillus.

[0053] After expanding the culture medium of each Bacillus strain, they were inoculated into their respective main fermentation tanks, and fermented at a temperature of 32-35°C, a pH value of about 6.5, and a stirring rate of about 200r / min. Cultivate for about 8-10 hours to reach the logarithmic growth phase, then add about 0.01ppm of nano-silicon material (particle size is 100 nanometers to 10 microns) to the fermentation broth of each bacillus, continue to cultivate for about 60 minutes, and then add each bacillus About 0.01ppm of carbon nanomaterials (with a particle size of 5-150 nanometers) were added to the fermentation liquid of the above-mentioned fermente...

Embodiment 3

[0063] 1. Preparation of microbial agents

[0064] Bacillus subtilis, Bacillus jelly-like, Bacillus licheniformis and Bacillus thuringiensis are respectively activated, and after activation, they are respectively inoculated into respective strain culture medium to obtain the strain culture liquid of each Bacillus.

[0065] After expanding the culture medium of each bacillus, they were inoculated into their respective main fermenters, and cultivated under the conditions of a temperature of 33-37°C, a pH value of 7-7.5, and a stirring rate of 120r / min. Cultivate about 8-10h to reach the logarithmic growth phase, then add about 1ppm of nano-silicon material (particle size is 100 nanometers to 10 microns) to the fermentation broth of each bacillus, continue to cultivate for about 30min, and then add to the fermentation broth of each bacillus About 1ppm of micro-nano carbon (particle size: 5-150 nanometers) is added to the fermentation liquid, and the culture is continued for about...

Abstract

The invention provides a composite soil modifying agent and a preparation method and application thereof. The composite soil modifying agent is prepared from the components, by weight, of 100 parts of microbial agent, 1-50 parts of micro-nano material and 0.1-50 parts of medium trace elements; the microbial agent is obtained by fermentation of bacillus, and the micro-nano material of 0.01-1 ppm is added in the fermentation process. According to the composite soil modifying agent, the usage amount of the fertilizer can be reduced, the soil is modified, the crop pest is reduced, and the yield and the quality of the crop are improved.

Description

technical field [0001] The invention relates to a soil conditioner, in particular to a composite soil conditioner and its preparation method and application. Background technique [0002] At present, due to the continuous application of chemical fertilizers, pesticides, insecticides and irrational use of land and many other factors, soil degradation is serious, which causes soil compaction and pollution, reduces soil productivity, crop yield and quality, not only for crops The safety has buried hidden dangers, and also polluted the water quality and the environment. [0003] Soil improvement is the process of taking corresponding physical, chemical or biological measures to improve soil properties, soil fertility, crop production, and the soil environment for human survival in response to the poor texture and structure of the soil. There are many kinds of soil improvers, mainly including lignite, lime, vermiculite, bentonite, perlite and other mineral improvers, straw, cell...
