Biomass charcoal-based fertilizer

Abstract

The invention provides a biomass charcoal-based fertilizer which comprises the following components in parts by weight: 20-25 parts of urea, 25-31 parts of a phosphate fertilizer, 16-28 parts of a potash fertilizer, 9-11 parts of biomass charcoal, 1-2 parts of fulvic acid, 1-7 parts of organic matters and 1-2 parts of a condiment, wherein the condiment is a mixture of an anti-caking agent, bentonite and a coating agent. Due to adoption of the organic matters and the fulvic acid, sufficient organic nutrients can be provided for crops to grow, and growth and development of plants can be promoted; due to adoption of the fulvic acid, on one hand, a synergetic effect on the urea, the phosphate fertilizer and the potash fertilizer in the biomass charcoal-based fertilizer can be achieved, and theutilization rate of the organic nutrients by the crops can be increased; with the combination of biomass charcoal, the fulvic acid and the organic matters, the fulvic acid and the organic matters canbe slowly released from the biomass charcoal, the fertilizer effect can be prolonged, the organic nutrients can be further enriched, and meanwhile the utilization rates of nutrients can be increased.

Description

technical field

[0001] The invention relates to the technical field of agricultural fertilizers, in particular to a biomass charcoal-based fertilizer. Background technique

[0002] As a means to increase crop yield, the application of chemical fertilizers plays an important role in my country's agriculture, but there are also a series of problems, the most important of which is the low utilization rate of chemical fertilizers. Excessive application of chemical fertilizers at one time exceeds the absorption capacity of the soil. Under the action of rainfall and irrigation, it penetrates downward into the groundwater, causing the loss of nutrients, causing soil barrenness and soil compaction, and the decline of fertility, which affects the growth of crops. Biomass charcoal can be formed by pyrolysis and carbonization of crop straw or kitchen waste. By combining biochar with inorganic fertilizers to produce organic and inorganic fertilizers, it can slow the release of chemical ...

Examples

Embodiment 1

[0018] This embodiment provides a kind of biomass charcoal-based fertilizer, including 20kg of urea, 25kg of monoammonium phosphate, 16kg of potassium sulfate, 9kg of biochar, 1kg of fulvic acid, 1kg of organic matter, and 1kg of small material, wherein the small material is anti-coagulation A mixture of block, bentonite and coating agent in equal parts by mass. Organic matter is obtained by mixing plant straw and peat soil at a mass ratio of 1:1, fermenting for 15 days, drying and crushing.

Embodiment 2

[0020] This embodiment provides a biomass charcoal-based fertilizer, including 25kg of urea, 31kg of monoammonium phosphate, 28kg of potassium chloride, 11kg of biomass charcoal, 2kg of fulvic acid, 7kg of organic matter, and 2kg of small materials. A mixture of caking agent, bentonite and coating agent in equal parts by mass. Organic matter is obtained by mixing plant straw and peat soil at a mass ratio of 1:1, fermenting for 20 days, drying and crushing.

Embodiment 3

[0022] This embodiment provides a biochar-based fertilizer, including 22kg of urea, 28kg of monoammonium phosphate, 22kg of potassium chloride, 10kg of biomass charcoal, 1kg of fulvic acid, 4kg of organic matter, and 1kg of small materials. A mixture of caking agent, bentonite and coating agent in equal parts by mass. Organic matter is obtained by mixing plant straw and peat soil at a mass ratio of 1:1, fermenting for 18 days, drying and crushing.
