Composite functional soil repair microbial agent and preparation method thereof

Abstract

The invention discloses a composite functional soil repair microbial agent and a preparation method thereof. The microbial agent comprises, by weight, 10-15 parts of lactobacillus, 3-7 parts of saccharomycetes, 7-15 parts of antinomycetes, 2-8 parts of soy peptone, 1-5 parts of carrageen, 1-5 parts of gelatin, 10-20 parts of potassium fulvate, 5-8 parts of humic acid ore powder, 2-9 parts of tea seed meal, 1-3 parts of tobacco stalk powder, 3-6 parts of powdery sodium silicate and 2-4 parts of zeolite powder. By combining potassium fulvate, gelatin and high-quality organic matter, acidic soilcan be improved and regulated effectively, crop rhizosphere soil micro-ecological environment can be improved remarkably, nutritional ingredients can be provided for plant growth, and impact of a soilconditioner on strain activity is avoided; the microbial agent can utilize surplus nutrient deposited in soil for fermentation, so that the soil is enabled to be balanced and reasonable in element, and soil hardening is improved.

Description

technical field [0001] The invention relates to the technical field of soil remediation bacterial agents, in particular to a composite functional soil remediation bacterial agent and a preparation method thereof. Background technique [0002] my country has a large population and a small arable area. The land has been under excessive use for a long time, and unscientific farming methods have caused serious problems in my country's arable land, such as soil pollution, nutrient loss, hardening and acidification. Among them, soil acidification has a particularly serious impact on the growth and yield of crops. Most crops are grown in slightly acidic or slightly alkaline soils. An overacid environment will make the roots of crops unable to absorb and secrete substances normally, resulting in insufficient root nutrition. In general, crops grow slowly and are prone to diseases. When this happens, a large amount of inorganic fertilizers and irrigation are often used. The low absorp...

Problems solved by technology

Among them, soil acidification has a particularly serious impact on the growth and yield of crops. Most crops are grown in slightly acidic or slightly alkaline soils. An overacid environment will make the roots of crops unable to absorb and secrete substances normally, resulting in insufficient root nutrition. In general, crops grow slowly and are prone to diseases. When this happens, a large amount of inorganic fertilizers and irrigation are often used. The low absorption rate of inorganic fertilizers leads to the deposition of a large number of elements, and irrigation will cause the loss of some easily soluble elements. Elemental imbalance

[0003] At present, there are still some deficiencies in the existing composite functional soil remediation bacterial agents, for example; Plant growth provides nutrients, which can easily lead to the impact of soil amendments on the activity of bacteria, and bacteria agents cannot use the excess nutrients deposited in the soil for fermentation
