Organic fertilizer containing humus and amino acid and preparation method thereof

Abstract

The invention provides an organic fertilizer containing humus and amino acid. The fertilizer comprises the following raw materials: potassium fulvate, peat, ursolic acid, Chinese medicine residue, tofu residue, humus, amino acid, 4-menth-1-en-4-ol, unsaturated polyester resin powder, Vulpia myuros plant, coal cinder, a Poria cocos extract, salt tolerant Rhodopseudomonas capsulata, and Halobacterium cutirubrum. The invention also provides a preparation method of the fertilizer. The fertilizer prepared by the method provided by the invention has an effective living bacteria number of 0.74-0.76billion cfu / g, a total nitrogen content of 3.3-3.5wt%, a total phosphorus content of 2.4-2.5wt%, a total potassium content of 3.4-3.6wt%, an organic matter content (on a dry basis) of 45.6-46.3wt%, a water content of 20.4-20.7wt%, pH of 5.56-5.63, a particle size (1-3mm) accounting for 98.7-98.9%, and a mixed bacteria rate of 2.3-2.5%.

Description

technical field [0001] The invention relates to an organic fertilizer containing humus and amino acid and a preparation method thereof, and belongs to the technical field of saline-alkali soil improvement fertilizer. Background technique [0002] Organic fertilizers are rich in organic matter and nutrients needed for crop growth. They can not only provide the nutrients needed for crop growth, improve the soil, but also improve crop quality, increase crop yield, promote high and stable crop yields, maintain soil fertility, and increase fertilizer efficiency. Utilization rate, reduce production cost. The full and rational use of organic fertilizers can increase crop yields, improve soil fertility, improve the quality of agricultural products, and increase the effectiveness of soil nutrients. Therefore, the promotion and application of organic fertilizers in our country is in line with the requirements of "accelerating the construction of a resource-saving and environment-frie...

AI Technical Summary

Problems solved by technology

[0006] (1) There are no effective microorganisms or there are low effective bacteria content and excessive bacteria, and some manufacturers add inappropriate amounts of chemical fertilizers or other additives to biological fertilizers, so that the nitrogen, phosphorus, and potassium content of chemical fertilizers in fertilizers are too high Lead to the death of effective bacteria, and lose the role of biological fertilizer, high heavy metal content;

[0007] (2) It cannot effectively reduce the salinity and soil pH of the soil at the same time; reduce the soil bulk density, increase the content of water-stable aggregate structure in the soil; increase the air permeability of the soil, and increase the number of microorganisms in the soil, and improve the water absorption and release of the soil Water rate; increase nitrogen, phosphorus and potassium content in soil ponds;

[0008] (3) Cannot reduce the heavy metal content in saline-alkali land;

[0009] (4) For soybean planting in saline-alkali land, the survival rate of soybean is low; the yield per mu is low, and the content of calcium and iron in soybean is low;

[0010] (5) It is used for soybean planting in saline-alkali land, and has no control effect on weeds Commelina and Cuscuta in soybean planting;
