Embodiment 1

[0019] The basic raw materials are respectively ground and passed through an 80-mesh sieve, mixed and kept at 50° C. and a relative humidity of 30% for 2 hours to obtain a mixture of basic raw materials. Among them, the mass ratio of basic raw materials includes: 20 parts of nitrogen fertilizer, 5 parts of potassium fertilizer, 15 parts of phosphate fertilizer, 1 part of humic acid, and 1 part of straw (wheat straw, rice orange stalk, Composed of corn stalks), 2 parts of soybean meal, 6 parts of rice husk powder, 3 parts of clay, 0.5 parts of medical stone, 4 parts of phosphate rock powder, 2 parts of peat soil, 1 part of zeolite powder, and 5 parts of vermicompost. Add 0.03 parts of strains to 0.2 parts of seaweed extract and mix evenly to obtain the additive. The additives are mixed and added to the mixture of basic raw materials, stirred and mixed evenly, and then granulated to obtain fertilizer granules. After the fertilizer granules are dried at 40°C until the moisture c...

Embodiment 2

[0022] The basic raw materials were respectively ground and passed through an 80-mesh sieve, mixed and then kept at 62°C and 40% for 3 hours to obtain a mixture of basic raw materials. Among them, the mass ratio of basic raw materials is: 25 parts of nitrogen fertilizer, 7 parts of potassium fertilizer, 22 parts of phosphate fertilizer, 3 parts of humic acid, 6 parts of straw (from corn straw and cotton straw with a mass ratio of 1:3:1 , sugarcane stems and leaves), 4 parts of soybean meal, 8 parts of rice husk powder, 10 parts of clay, 3 parts of medical stone, 8 parts of phosphate rock powder, 3 parts of peat soil, 2 parts of zeolite powder, and 7 parts of vermicompost. Add 0.1 part of strain and 0.5 part of chitin to a liquid material composed of 0.4 part of seaweed extract and 2 parts of acetic acid and mix evenly to obtain the additive. The additives are mixed and added to the mixture of basic raw materials, stirred and mixed evenly, and then granulated to obtain fertiliz...

Embodiment 3

[0025] The basic raw materials were respectively ground and passed through an 80-mesh sieve, mixed and kept at 56° C. and a relative humidity of 35% for 2.5 hours to obtain a mixture of basic raw materials. Among them, the mass ratio of basic raw materials includes: 22 parts of nitrogen fertilizer, 6 parts of potassium fertilizer, 18 parts of phosphate fertilizer, 2 parts of humic acid, 3 parts of straw (wheat straw, rapeseed orange stalk, tobacco Rod composition), 3 parts of soybean meal, 7 parts of rice husk powder, 7 parts of clay, 2 parts of medical stone, 6 parts of phosphate rock powder, 2.5 parts of peat soil, 1.5 parts of zeolite powder, and 6 parts of vermicompost. The additive is obtained by adding 0.06 parts of strains and 0.2 parts of chitin to a liquid material composed of 0.3 parts of seaweed extract and 1 part of acetic acid. The additives are mixed and added to the mixture of basic raw materials, stirred and mixed evenly, and then granulated to obtain fertilize...

Abstract

The invention provides a biological organic fertilizer. The biological organic fertilizer comprises the following raw materials in parts by mass: 20-25 parts of a nitrogen fertilizer, 5-7 parts of a potash fertilizer, 15-22 parts of a phosphate fertilizer, 1-3 parts of humic acid, 1-6 parts of straws, 2-4 parts of soybean meal, 6-8 parts of rice husk powder, 3-10 parts of clay, 0.5-3 parts of maifan stone, 4-8 parts of ground phosphate rock, 2-3 parts of peat soil, 1-2 parts of zeolite powder, 5-7 parts of earthworm feces, 0.03-0.1 part of strains, and 0.2-0.4 part of a seaweed extraction liquid. The biological organic fertilizer provided by the invention has the effective technical effects that proportioning of the above organic and inorganic components is performed according to a specialratio, the effective strains are added, so that industrial waste can be utilized in an environmentally-friendly manner; and in particular, the seaweed extraction liquid can make the strains stored for a long time, and the strains are uniformly dispersed into each inorganic component through mixing, so that the strains can better transfer beneficial components in the inorganic components, and thebiological organic fertilizer has high stability, high fertilizer efficiency, a long fertilizer effect, and lower costs.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a bio-organic fertilizer. Background technique [0002] Fertilization is an important technical measure in agricultural production. Reasonable fertilization can supplement soil nutrients and increase crop yield. However, unreasonable fertilization, especially large-scale and long-term use of chemical fertilizers, will easily lead to a decrease in organic matter content in the soil, soil acidification, compaction, imbalance of soil flora, increase of harmful bacteria and harmful substances, and decline of soil fertility. The abuse of chemical fertilizers and pesticides has also caused a large increase in chemical residues and other harmful substances in agricultural products, and the quality has declined, affecting human health and survival. Therefore, the production of organic agriculture and pollution-free agricultural products has attracted more and more attention, and bio...
