Problems solved by technology

[0002] In the current agricultural activities, due to the frequent use of chemical fertilizers or pesticides on the soil, some of these chemical fertilizers are single fertilizers that only contain a large amount of inorganic compounds, which can achieve a certain effect in a short period of time, but after one or a few times , will cause soil agglomeration, which greatly reduces the soil quality, which is very unfavorable for the next planting on the used land
[0003] At the same time, due to the increase in the use rate and amount of pesticides, a large amount of heavy metals, organic phosphorus, etc. will be left in the soil. Harmful substances to the human body, such soil poses a great threat to the environment
[0004] However, if pesticides and chemical fertilizers are not used, a variety of microorganisms harmful to crops may grow in the soil, such as root-knot nematodes that attack the roots of crops, affect the growth of crops, and may even cause the death of crops. have adverse effects

preparation example Construction

[0017] The preparation method of above-mentioned anti-disease microbial soil restoration agent comprises:

[0018] The carrier was pulverized and sieved to obtain the first sample. Before the carrier is pulverized, a soil conditioner is preferably added therein. The soil conditioner is preferably chemical substances such as maleic acid, polyacrylic acid, and polyvinyl alcohol. The soil conditioner can increase the gap between the carrier molecules. In the subsequent steps, the bacterial agent can be more fully adsorbed; after crushing, sieve, preferably with a sieve hole of 0.1cm to 2cm, the carrier within this range has a good adsorption effect, and the sample particles will not be too small and inconvenient Next step.

[0019] Fermenting the microbial agent to obtain a second sample. When fermenting the microbial inoculum, the preferred method is to separately ferment different strains in the microbial inoculum to obtain a plurality of bacterial liquids, and then inoculate...

Embodiment 1

[0026] 100 kg of dried bentonite was weighed, 0.5 kg of maleic acid was added thereto and crushed, and passed through a sieve with a diameter of 0.5 cm to obtain a first sample.

[0027] Get Bacillus megaterium, jelly-like Bacillus, Paecilomyces lilacinus, Bacillus sporogenes and Bacillus subtilis each 10kg, in five petri dishes, the above five strains are respectively fermented, the present embodiment selects beef extract Agar medium; the temperature of the entire fermentation process is controlled at 33°C, and the existing intelligent temperature controller is selected to regulate and control the temperature of the entire fermentation process; at the beginning of the fermentation process, the pH of the fermentation environment is adjusted to 5.5 with citric acid. No further intervention or adjustment of the pH was carried out during the fermentation process. The whole fermentation process lasts continuously for 72 hours, and the bacterial liquid of each bacterial species is ...

Embodiment 2

[0031] Weigh 50kg of diatomaceous earth, 25kg of chicken manure and 25kg of duck manure and mix them, then add 0.5kg of polyacrylic acid and crush them, pass through a sieve with a diameter of 0.8cm, and obtain the first sample.

[0032] Get Bacillus megaterium, jelly-like Bacillus, Paecilomyces lilacinus, Bacillus lateralis and Bacillus subtilis, each 10kg of Bacillus licheniformis, in six petri dishes, above six bacterial classifications are fermented respectively, this implementation For example, pea agar medium is selected as the culture substrate; the temperature of the entire fermentation process is controlled at 36°C, and the existing intelligent temperature controller is selected to regulate and control the temperature of the entire fermentation process; at the beginning of the fermentation process, malic acid is used to adjust the pH of the fermentation environment Adjusted to 6, no pH intervention or adjustments were made during the remainder of the fermentation. The...

Abstract

The invention provides a disease-resistant microbial soil remediation agent and a preparation method thereof, and relates to the field of agriculture. The disease-resistant microbial soil remediation agent is prepared by fermenting a microbial agent and inoculating the fermented microbial agent to a carrier, the microbial agent comprises bacillus megatherium, bacillus mucilaginosus, paecilomyces lilacinus, bacillus laterosporus and bacillus subtilis, and the weight ratio of the microbial agent before fermentation and the carrier is 1:(1-5). The disease-resistant microbial soil remediation agent can effectively increase the yield of crops, improve the quality of the crops, prevent and treat diseases and pest damage which possibly occur in the crop growth process and also can maintain or improve the soil quality. In addition, the invention relates to the preparation method of the disease-resistant microbial soil remediation agent. The preparation method is simple, the raw materials are easy to obtain and reasonable in price, and industrial large-scale production is easy to achieve.
