Problems solved by technology

However, this medicinal fertilizer is mainly applied on the surface of crops, and is used more as a medicine. It does not have the effect of improving soil structure, cannot solidify heavy metals in the soil, and cannot provide the soil with nutrients needed for long-term growth.

Embodiment 1

[0039] Embodiment 1 adopts the application experiment of the biological organic fertilizer of different plant growth regulators

[0040] The following plant growth regulator groups were used and bio-organic fertilizers were prepared according to the formula 1 in Table 1 and the above-mentioned preparation method. All raw materials were obtained from commercial purchases except waste white clay. The waste white clay was self-produced waste white clay with an oil content of about 13-14% ( The decolorized waste white clay containing 20-30% oil is obtained by physical pressing at normal temperature).

[0041] Plant growth regulator groups 1-7: brassinolide and cytokinin in mass ratios of 1:45, 1:50, 1:100, 1:200, 1:300, 1:350 and 1:380 ;

[0042] Plant growth regulator groups 8-12: brassinolide and thiadiuron mixed in a mass ratio of 1:0.8, 1:1, 1:5, 1:10, 1:11;

[0043] Plant growth regulator groups 13-19: brassinolide and gibberellic acid in mass ratios of 1:9, 1:10, 1:20, 1:3...

Embodiment 2

[0059] This example provides a kind of bio-organic fertilizer, its raw material formula is shown in Table 1 formula 2, wherein the oil content of waste clay is about 13-14%, and the plant growth regulator is brassinolide and cytokinin in a mass ratio of 1:100 Mix composition. Each component is individually packaged. Before use, make organic fertilizer according to the above-mentioned method of the present invention.

Embodiment 3

[0061] This example provides a kind of biological organic fertilizer, its raw material formula sees formula 3 in Table 1, wherein the oil content of waste clay is about 13-14%, and the plant growth regulator is brassinolide and thiadizuron in a mass ratio of 1:5 Mix composition. Each component is individually packaged. Before use, make organic fertilizer according to the method of the present invention.

Abstract

The invention provides a spent bleaching clay-based bio-organic fertilizer, the raw material formula of which includes the following raw materials in parts by weight: 50-70 parts of spent bleaching clay, 10-15 parts of humic acid, 0.5-2 parts of composite bacteria liquid, 0.5-1 part of complex enzyme, 5-10 parts of magnesium aluminum silicate and 0.01-0.1 part of plant growth regulator, wherein the composite bacteria liquid is prepared by mixing pseudomonas, bacillus subtitles, white rot fungi, bacillus cereus, and bacillus thuringlensis according to the volume ratio of nutrient solution being 1 to (1.3-1.6) to (0.5-1.1) to (0.3-0.6) to (0.2-0.4); the complex enzyme is formed by mixing amylase, lipase and ligninase according to the mass ratio of 1 to (1.4-1.6) to (0.3-0.8); and the plant growth regulator is a combination of brassinolide with one or more of cytokinin, thidiazuron, gibberellic acid, indoleacetic acid and naphthalene acetic acid. The bio-organic fertilizer has multiple functions of preventing soil pests, degrading pesticide and chemical residuals in soil, curing and stabilizing heavy metal ions in the soil, is excellent in comprehensive modification effect, has no root burning and seedling burning problems and is low in cost.

Description

technical field [0001] The invention relates to a bio-organic fertilizer based on waste white clay and its application. Background technique [0002] In agricultural planting, there are two common problems, one is the harm of root nematodes and soil-borne diseases to crops, and the other is the huge economic loss caused by the excessive use of chemical fertilizers and pesticides, which makes the chemical residues of agricultural products exceed the standard. In addition, due to the discharge of industrial "three wastes" and the migration of contaminated soil from sewage farmland irrigation and sludge agricultural areas due to urban development and construction, a large amount of calcium superphosphate fertilizers containing Cd impurities and animal manure with high Zn content have been used in large quantities. The accumulation of heavy metal pollutants such as Cd, Hg and Zn has exceeded the standard for a long time, and there are persistent organic pollutants in pesticides ...
