preparation example Construction

[0022] Some embodiments of the present invention also provide a preparation method of the above-mentioned acidified and compacted soil remediation bacterial agent, which includes: microbial bacterial agent, oyster shell powder, nano-microelectric energy materials, mineral humic acid, amino acids, enzymatic alginic acid and Anionic polyacrylamide mixed evenly.

[0023] Further, in some embodiments, the preparation of the microbial inoculum comprises the following steps: inoculating the strains of the microbial inoculum into the medium for liquid fermentation culture, preferably, the inoculation amount is 0.1-0.3%; fermenting the collected The solution is mixed with diatomaceous earth for adsorption, dried and pulverized. Wherein, the mass ratio of diatomaceous earth to fermentation broth may be 7-9:1, preferably 8:1.

[0024] Specifically, in some embodiments, the carbon source of the culture medium includes at least one of sucrose, starch, glucose and lactose. Preferably at ...

Embodiment 1

[0045] The preparation method of a kind of acidified compacted soil remediation bacterial agent provided by the present embodiment comprises the following steps:

Abstract

The invention discloses an acidified hardened soil restoring bacterial agent as well as a preparation method and application method thereof. The acidified hardened soil restoring bacterial agent is mainly prepared from the following ingredients in parts by weight: 10 to 30 parts of microbial agents used for obtaining exopolysaccharides through secretion, 10 to 25 parts of oyster shell powder, 2 to5 parts of nanometer micro electric power materials, 5 to 25 parts of mineral humic acid, 5 to 10 parts of amino acid, 5 to 10 parts of enzymatically hydrolyzed alginic acid and 2 to 5 parts of anionic polyacrylamide. The acidified hardened soil restoring bacterial agent is obtained through compounding various raw materials according to a specific proportion; the soil acidification and hardeningproblems can be effectively improved or prevented; soil is loosed and ventilated; the breath and growth of microbes and plant root systems in the soil are facilitated; meanwhile, the buffer capabilityof the soil is improved; the health and sustainable utilization of the soil can be promoted; and a great significance on the sustainable development of agriculture is realized. The preparation methodof the acidified hardened soil restoring bacterial agent is simple in process, and is applicable to large-scale production.

Description

technical field [0001] The invention relates to the field of soil remediation agents, in particular to an acidified compacted soil remediation bacterial agent and a preparation method thereof. Background technique [0002] Soil acidification refers to the process in which the pH value of the soil decreases continuously and the exchangeable acidity of the soil increases continuously. It is a natural process accompanied by the occurrence and development of the soil. It mainly produces hydrogen ions (H + )drive. The natural acidification process of soil is relatively slow, but due to the impact of high-intensity human activities in recent decades, the process of soil acidification has been greatly accelerated, causing serious harm to the ecological environment and agricultural production, especially in tropical and subtropical regions in southern my country. The impact of human activities on acidification mainly includes atmospheric acid deposition and inappropriate agricultur...
