Problems solved by technology

Due to excessive fertilization, it also pollutes the environment, causing soil compaction and physical structure damage
In addition, the fertilizer utilization rate in my country is not as good as that in developed countries, mainly because the structure of the soil changes and the ability to store water and fertilizer decreases.
Although agricultural compost and organic fertilizer can completely avoid the above problems, the simple application of organic fertilizer is not feasible in modern agricultural production.

Embodiment 1

[0028] Example 1 A biological organic-inorganic compound fertilizer (granular product), the raw material components and parts by weight are as follows: lignin 30, chicken manure 20, ammonium bicarbonate 25, diammonium phosphate 32, potassium chloride 15, EM bacteria powder 0.2, subtilis Bacillus bacteria powder 0.2.

[0029] The preparation method steps are:

[0030] 1. Dry the fermented organic fertilizer with a dryer, reduce the moisture to below 15%, remove the sundries, and then use an organic fertilizer grinder to crush it to more than 60 mesh;

[0031] 2. Mix the crushed organic fertilizer, nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, EM powder, Bacillus subtilis powder, and lignin powder in proportion, stir them evenly and send them to the granulator for granulation, 30-50°C (Lignin) bio-organic-inorganic compound fertilizer products are obtained after drying under high temperature.

Embodiment 2

[0032] Example 2 A kind of bio-organic-inorganic compound fertilizer, the preparation method is the same as that of Example 1, but the components and parts by weight of each raw material are as follows, lignin 20, cow dung 10, urea 15, calcium magnesium phosphate fertilizer 38, potassium sulfate 5, EM bacteria powder 0.1 , Bacillus subtilis powder 0.1.

Embodiment 3

[0033] Example 3 A kind of bio-organic-inorganic compound fertilizer, the preparation method is the same as in Example 1, but each raw material component and parts by weight are as follows, lignin 28, pig manure 18, ammonium bicarbonate 22, calcium magnesium phosphate fertilizer 30, potassium nitrate 12, EM bacteria Powder 0.18, Bacillus subtilis powder 0.18.

Abstract

The invention discloses biological, organic and inorganic compound fertilizer. The biological, organic and inorganic compound fertilizer comprises, by weight, 20-30 parts of lignin, 10-20 parts of organic fertilizer, 15-25 parts of nitrogen fertilizer, 30-40 parts of phosphorus fertilizer, 5-15 parts of potassium fertilizer, 0.1-0.2 part of EM (effective microorganisms) fungus powder, and 0.1-0.2 part of bacillus subtilis powder. Therefore, microenvironment of soil can be improved evidently, activity of beneficial microorganisms in soil is facilitated, and releasing of phosphorus in soil is facilitated.

Description

technical field [0001] The invention belongs to the field of soil fertilizer technology, and in particular relates to a bio-organic-inorganic compound fertilizer and a preparation method thereof. Background technique [0002] China is a large agricultural country, and its agricultural water consumption ranks among the highest in the world. With the excessive exploitation of groundwater and farmers' excessive reliance on chemical fertilizers, the degree of secondary salinization of the soil has increased year by year. At present, agricultural production is too dependent on chemical fertilizers. The production and use of chemical fertilizers in my country ranks first in the world, and excessive fertilization exists in most areas. According to statistics, in the past few years, the use of chemical fertilizers in my country has increased by 36.9%, but in fact the total grain output has only increased by 4.7%, that is, the input has increased but the output has not increased.
