Biological enzyme soil improver and preparation method thereof

Abstract

The invention provides a biological enzyme soil improver and a preparation method thereof. The invention provides the biological enzyme soil improver capable of adjusting the alkalinity and acidity of soil and the preparation method of the biological enzyme soil improver. The biological enzyme soil improver is prepared from the following components in parts by mass: 25 to 35 parts of lactic acid bacteria, 8 to 12 parts of nitrogen-fixing bacteria, 8 to 12 parts of actinomyces, 3 to 8 parts of silicate bacteria, 6 to 10 parts of bacillus subtilis, 2 to 5 parts of beauveria bassiana, 2 to 5 parts of metarhizium anisopliae, 3 to 8 parts of paenibacillus polymyxa, 3 to 8 parts of trichoderma viride, 8 to 12 parts of saccharomycetes, 3 to 8 parts of photosynthetic bacteria and 0.7 to 1.1 parts of a biological enzyme, wherein the concentration of effective living bacteria is 10billion / mL to 20billion / mL. According to the biological enzyme soil conditioner provided by the invention, various beneficial microorganism florae are scientifically proportioned; meanwhile, a novel amino acid state chelating agent is utilized and the growth and the proliferation of complex flora are accelerated; meanwhile, the chelating capability on microelements is enhanced in the presence of ultrasonic waves, the utilization rate is greatly improved and the yield increasing effect is very remarkable.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a biological enzyme soil improver and a preparation method thereof. Background technique [0002] Due to the difference in climate between the north and the south of my country, the south is humid and rainy, and the soil is mostly acidic, while the north is dry and rainless, and the soil is mostly alkaline. The partial (over)acidity or partial (over)alkalinity of the soil will reduce the availability of soil nutrients to varying degrees, and the specific performances are as follows: (1) The availability of phosphorus in the soil is obviously affected by the acidity and alkalinity, When the pH value exceeds 7.5 or is lower than 6, phosphoric acid and calcium or iron and aluminum will form a slow-acting state, which will reduce the effectiveness; calcium, magnesium and potassium are easily replaced and leached in acidic soil. The solubility is low in alkaline soil, and th...

Problems solved by technology

The partial (over)acidity or partial (over)alkalinity of the soil will reduce the availability of soil nutrients to varying degrees, and the specific performances are as follows: (1) The availability of phosphorus in the soil is obviously affected by the acidity and alkalinity, When the pH value exceeds 7.5 or is lower than 6, phosphoric acid and calcium or iron and aluminum will form a slow-acting state, which will reduce the effectiveness; calcium, magnesium and potassium are easily replaced and leached in acidic soil. The solubility is low in alkaline soil, and the effectiveness is reduced; trace elements such as boron, manganese, copper, etc., are greatly reduced in availability in alkaline soil, and the precipitation of molybdenum and free iron and aluminum in strong acidic soil reduces the effectiveness (2) There are more hydrogen and sodium in strong acidic soil and strong alkaline soil, but lack of calcium, it is difficult to form a good soil structure, which is not conducive to crop growth; (3) the most suitable pH value for soil microorganisms is generally between 6.5 and 7.5 In the neutral range, over-acid or over-alkali will seriously inhibit the activities of soil microorganisms, thereby affecting the transformation and supply of nitrogen and other nutrients; (4) general crops are most suitable for growth in neutral or near-neutral soil, sugar beet , alfalfa, and red clover are not suitable for acidic soil; tea requires strong acidity and acidic soil, and neutral soil is not suitable for growth; (5) If the soil is too acidic, it is easy to produce free Al3+ and organic acids, which directly harm crops

When the soluble salt in alkaline soil reaches a certain amount, it will directly affect the germination and normal growth of crops, and the alkaline soil containing more sodium carbonate will be more toxic to crops

[0003] Existing soil improvers have single effects, most of which are aimed at increasing soil nutrients, and rarely involve adjusting soil acidity and alkalinity, and do not fundamentally solve soil problems, so the improvement effect is not obvious
