Problems solved by technology

However, the organic matter of the above-mentioned carbon-based fertilizer mainly comes from animal manure, and the nutrition is single. When it is actually applied to bamboo forests, due to the heat generated by the fermentation of manure, it will cause damage to the roots of bamboo forests and affect the output of bamboo shoots.

Embodiment 1

[0035] A special biochar-based fertilizer for bamboo forests, including 30kg of biochar, 45kg of inorganic fertilizer, 10kg of organic waste aerobic fermentation fertilizer, and 1kg of binder. The binder can use cyclodextrin or modified starch, preferably cyclodextrin . The biochar-based fertilizer has an effective nutrient weight percentage of 25 wt%, a total C content of 35 wt%, and a pH of 7.0.

[0036] In this embodiment, the inorganic fertilizer can be any one or more of urea, potassium sulfate, and diammonium phosphate, and the particle size of the biochar-based fertilizer is 4mm. The organic waste aerobic fermentation fertilizer can be prepared by the method of step B in Example 4. Biochar can be any one or several of corn straw, rice straw, wheat straw, and sorghum straw. Carbonized biochar.

Embodiment 2

[0038] A special biochar-based fertilizer for bamboo forests, comprising 40kg of biochar, 35kg of inorganic fertilizer, 20kg of organic waste aerobic fermentation fertilizer, and 2kg of binder, wherein the binder is selected from modified starch. The biochar-based fertilizer has an effective nutrient weight percentage of 32%, a total C content of 45 wt%, and a pH of 6.0.

Abstract

The technical field of carbon-based fertilizer, and relates to special biological carbon-based fertilizer for a bamboo forest, a preparation method and an application of the special biological carbon-based fertilizer. The biological carbon-based fertilizer comprises the following ingredients: biological carbon, inorganic fertilizer, organic waste aerobic fermentation fertilizer and an adhesive agent. The preparation method comprises the following steps of: A, collecting organic crop biomass, after drying, putting the organic crop biomass in a biological carburization furnace for high temperature calcination, obtaining biological carbon after carbonization, B, grinding, extruding and dehydrating organic waste, putting in a fermentation bin for fermentation for above 24h, removing a fermented material from the fermentation bin, performing second composting, obtaining the organic waste aerobic fermentation fertilizer after drying, and C, uniformly mixing and stirring the biological carbon, the organic waste aerobic fermentation fertilizer, the inorganic fertilizer and the adhesive agent for granulating to form the special biological carbon-based fertilizer for the bamboo forest. According to the fertilizer, the method and the application, the compatibility is reasonable; since the organic waste aerobic fermentation fertilizer is added, the cost of the fertilizer can be effectively lowered; and both bamboo nutrient requirements and slow release of the organic fertilizer are considered.

Description

technical field [0001] The invention belongs to the technical field of charcoal-based fertilizers, and relates to a special biochar-based fertilizer for bamboo forests, a preparation method and an application thereof. Background technique [0002] Charcoal-based fertilizer is an eco-friendly fertilizer formulated with biochar as the substrate, based on soil texture, crop growth characteristics and scientific fertilization principles, adding organic matter or / and inorganic matter. Carbon-based fertilizers are divided into three basic types: carbon-based organic fertilizers, carbon-based inorganic fertilizers, and carbon-based organic-inorganic compound fertilizers (compound fertilizers). Carbon-based organic fertilizer refers to the ecological fertilizer formed by the reasonable combination of biochar powder and organic fertilizer; carbon-based inorganic fertilizer refers to the ecological fertilizer formed by the reasonable ratio of biochar powder and inorganic fertilizer; c...
