Problems solved by technology

[0007] In fact, before the invention of chemical fertilizers, humans have used organic fertilizers such as human feces and grass ash to fertilize and grow crops. However, due to the slow decomposition of traditional organic fertilizers, which are slow-acting fertilizers, it is easy to cause insufficient fertility and the grain output is still not high. Soil improvement and fertilization are indispensable

Embodiment 1

[0027] In this embodiment, the biogas slurry of the biogas digester is selected, and after 7 days of aeration and oxygenation aging, the solid biogas residue is removed with a filter screen; diatomite with a weight ratio of 10%, food flavor with a weight ratio of 0.5%, and biological bacteria are added Until the biological bacteria content reaches more than 5 billion / ml; add 15% by weight nitrogen fertilizer, 3% by weight phosphate fertilizer, and 3% by weight potassium fertilizer, stir evenly, and pack in plastic barrels to obtain the finished product. The nitrogen content of the product in this embodiment is relatively high, and it is especially suitable for fertilizing crops that require well-developed roots, such as peanuts, tobacco, fruit trees, and vegetables.

Embodiment 2

[0029] In this embodiment, the biogas slurry of the biogas digester is selected, and after 7 days of aeration and oxygenation aging, the solid biogas residue is removed with a filter screen; diatomite with a weight ratio of 10%, food flavor with a weight ratio of 0.5%, and biological bacteria are added Until the biological bacteria content reaches more than 5 billion / ml; add 5% nitrogen fertilizer, 13% phosphate fertilizer, and 3% potassium fertilizer by weight, stir evenly, and pack in plastic barrels to obtain the finished product. The product of this embodiment has relatively high phosphorus content, and is especially suitable for fertilizing crops that require flowering and fruiting, such as tomato.

Embodiment 3

[0031] In this embodiment, the biogas slurry of the biogas digester is selected, and after 7 days of aeration and oxygenation aging, the solid biogas residue is removed with a filter screen; diatomite with a weight ratio of 10%, food flavor with a weight ratio of 0.5%, and biological bacteria are added Until the biological bacteria content reaches more than 5 billion / ml; add 5% nitrogen fertilizer, 3% phosphate fertilizer, and 15% potassium fertilizer by weight, stir evenly, and pack it in a plastic bucket to obtain the finished product. The potassium content of the product of this embodiment is relatively high, and it is especially suitable for fertilizing crops that require well-developed stems, such as sugar cane, fruit, tea, and tobacco.

Abstract

The invention relates to the field of agricultural fertilizers and discloses an organic compound fertilizer which is prepared by adding biogas residues or biogas slurry which is oxygenated and matured into 20-25 weight percent of compound fertilizer and 5-15 weight percent of infusorial earth and then removing smell, stirring and packaging. The organic substance of the organic compound fertilizer can stimulate the roots of plants to accelerate the plants to absorb the compound fertilizer and fully embody the quick effective character of the compound fertilizer; the organic substance component in the biogas slurry is degraded in soil, thereby increasing the fertility of the soil and preventing the soil from leanness and hardening; and the active bacteria contained in the biogas slurry and the added bio-bacteria can accelerate the degradation of the compound fertilizer remained in the soil, thereby preventing the soil from acidifying.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to an organic compound fertilizer made from biogas slurry or biogas residue. Background technique [0002] Agriculture belongs to the primary industry, which solves the fundamental needs of human survival. With the growth of population, the requirements for food production are getting higher and higher to meet the needs of human survival. In order to increase production, humans invented hybrid rice and chemical fertilizers, providing food for more than 6 billion people in the world. However, the excessive use of pesticides and chemical fertilizers pollutes the food itself and the land, making the land barren and hardened. Developed countries have long banned or restricted the use of chemical fertilizers. For example, the United States has made strict regulations on the use of chemical fertilizers through legislation. According to the theory of soil fertilizer, when applyin...
