Embodiment 1

[0050] Present embodiment provides the microbial inoculant containing Trichoderma aculeatus spore powder and preparation method thereof, and the method comprises the steps:

[0051] 1), the preserved bacterial classification is first received on the PDA medium plate, activated and cultivated at 28°C until sporulation, and the resulting spore powder is sieved (200 mesh), to obtain the Trichoderma aculeatus spore powder;

[0052] Take the spore powder and make it into a concentration of 1×10 11 spore / mL suspension to obtain the first microbial liquid inoculant.

[0053] Wherein, the configuration method contained in the PDA medium mentioned above is as follows: Weigh 200g of potatoes, wash, peel and cut into small pieces, add 1000ml of water to boil for half an hour, filter with gauze, add 10-20g of glucose, fully dissolve Dilute to 1000ml and sterilize at 121°C for 30min.

[0054] 2) Take Bacillus stearothermophilus strains, pick a ring of strains and insert them into a 100ml...

Embodiment 2

[0060] In this example, the preparation operation is the same as in Example 1. The difference from Example 1 is that in this example, in addition to adding Bacillus stearothermophilus and Acremonium acremonium, Lactobacillus plantarum, Li Trichoderma, Lactobacillus delbrueckii, Micrococcus methanophilus, Thermoanaerobacillus metalophilus, Actinomyces albicans, the above strains are composed according to the ratio of 3:3:7:7:3:3:3 After adding the compound bacteria solution, the total amount of each bacteria added was 1×10 11 CFU / mL.

Embodiment 3

[0062] This embodiment provides a solid bacterial agent and a preparation method thereof, specifically comprising the following steps:

[0063] The liquid bacterial agent prepared in the above-mentioned Example 2 is added to the talcum powder according to the ratio of 20 grams of talc powder (as a solid carrier) per 1 kg of liquid bacterial agent, and fully stirred and mixed, filtered, dried, and pulverized to obtain a solid bacterial agent. agent.

Abstract

The invention relates to a microbial agent. The agent contains trichoderma asperellum WL, bacillus stearothermophilus viable spores and scopulariopsis acremonium. Organic wastes are composted by usingthe composite microbial agent, so that the material decomposition degree is improved, and the agent has the complexing action on heavy metal ions for changing the states of the heavy metal ions and also has excellent tolerance. The invention further relates to an organic waste desertified soilremediation agent. The organic waste desertified soil remediation agent is prepared by mixing a fermentation product and an organic waste preparation, wherein the fermentation product is prepared by fermenting the microbial agent and the organic wastes and auxiliary materials; and the preparation methodof the organic waste preparation comprises the following steps: removing impurities, crushing, soaking with water for 10-14 hours, stirring into paste in an environment with the pH value of 9-10, andadding a vinyl monomer to carry out a graft copolymerization reaction. The soil remediation agent solves the desertification problem, and is capable of remediating heavy metal contaminated soil.

Description

technical field [0001] The invention relates to the technical field of microbial application, in particular to a microbial bacterial agent, an organic garbage desertification soil remediation agent and a preparation method and application thereof. Background technique [0002] 43% of the land on the earth's surface is distributed in arid regions, and more than 110 countries are affected by desertification, which causes a huge loss of 82 billion U.S. dollars every year in the world. my country has a large area and wide distribution. The national desertification land area reaches 1.743 million square kilometers, accounting for 18% of the national land area, involving 841 counties (banners) in 30 provinces (autonomous regions, cities) across the country. The eight major deserts and the four major sandy lands are the main sand sources in my country, and there are sporadic sandy lands along the rivers, rivers, and seas in the south. The national area of ​​mobile sand dunes is 42...
