Problems solved by technology

These methods can solve the problem on the surface, but simply adjusting the ratio of several materials cannot form a stable and long-lasting high-end product; acidification of irrigation water with inorganic acids can easily lead to water pollution; waste of EC value is improved by leaching water resources
This kind of solution is relatively large investment, high cost, easy to pollute the environment, and the effect duration is short, easy to cause damage, not a long-term solution
Because the current composting technology is not up to standard, the product quality is uneven, the cost is high, and sales are difficult, so it is impossible to form a large-scale and industrialized operation model

Embodiment 1

[0054] 1. Pretreatment of agricultural and forestry waste raw materials

[0055] 1-1) Use a pulverizer to pulverize the branches of garden waste (the pruned branches of willow, locust tree, poplar, etc.), and pass through a sieve with an aperture of 2 cm to make waste particles with a particle size of ≤ 2 cm;

[0056] 1-2) Add urea to the waste granules, adjust the C / N ratio of the waste granules to 30:1, and make compost fermentation granules.

[0057] In the present invention, in addition to using urea to adjust the C / N ratio of waste particles, livestock and poultry manure (such as cow manure, chicken manure, horse manure, etc.) can also be used to increase the nitrogen content of waste.

[0058] During the fermentation process, the fermented granules selected by the present invention are fermented substrates with a particle size of 20-50 mm. The fermented granules within this particle size range are the most suitable initial particle size range for efficient fermentation o...

[0083] 1. Pretreatment of agricultural and forestry waste raw materials

[0084] 1-1) Use a pulverizer to crush the branches of garden waste (the pruned branches of willow, locust tree, poplar, etc.), pass through a sieve with an aperture of 5 cm, and make waste particles with a particle size of ≤ 5 cm;

[0085] 1-2) Add urea to the waste granules, adjust the C / N ratio of the waste granules to 20:1, and make compost fermentation granules.

[0086] 2. Preparation of fermentation catalyst

[0087] 2-1) Preparation of humic acid solution

[0088] Add humic acid into alkaline solution (concentration is the sodium hydroxide solution of 0.15mol / L), stir, dissolve evenly, make humic acid solution, wherein the concentration of humic acid solution is 1.5g / L, be about to 1.5g of humic acid is dissolved in 0.15mol / L sodium hydroxide solution, and fixed to 1L, that is to say, the ratio of the weight of humic acid in the humic acid solution to the volume of the alkaline solution is 1.5:1...

[0102] 1. Pretreatment of agricultural and forestry waste raw materials

[0103] 1-1) Use a pulverizer to crush the branches of garden waste (the pruned branches of willow, locust tree, poplar, etc.), pass through a sieve with an aperture of 2.5cm, and make waste particles with a particle size of ≤2.5cm ;

[0104] 1-2) Add urea to the waste granules, adjust the C / N ratio of the waste granules to 25:1, and make compost fermentation granules.

[0105] 2. Preparation of fermentation catalyst

[0106] 2-1) Preparation of humic acid solution

[0107] Add humic acid into alkaline solution (concentration is the sodium hydroxide solution of 0.25mol / L), stir, dissolve evenly, make humic acid solution, wherein the concentration of humic acid solution is 0.5g / L, be about to 0.5g humic acid is dissolved in 0.25mol / L sodium hydroxide solution, and fixed to 1L, that is to say, the ratio of the weight of humic acid in the humic acid solution to the volume of the alkaline solution is 0.5:1...

Abstract

A method of preparing a plant cultivation medium by utilizing agriculture and forestry waste and the prepared cultivation medium are disclosed. The method includes 1) spraying the agriculture and forestry waste with water to adjust the water content of the agriculture and forestry waste, and 2) adding a fermentation catalyst, a microbe agent and brown sugar into the agriculture and forestry waste, fully stirring and fermenting. The plant cultivation medium is balanced in nutrition, high in nutrient contents, reasonable in structure, stable in physical properties, and convenient for plant absorption, meets plant growth needs and increases the survival rate of plant cultivation and ornamental effects.

Description

technical field [0001] The invention relates to a method for utilizing agricultural and forestry waste, in particular to a method for composting agricultural and forestry organic waste and the composting of agricultural and forestry waste prepared by the method. Background technique [0002] Compost is a kind of organic fertilizer, which is rich in nutrients and has a long and stable fertilizer effect. Containing a single nutrient and long-term single use of chemical fertilizers are likely to cause soil compaction, water retention and fertilizer retention performance decline. Compost is an organic fertilizer made by composting and decomposing various plant residues (crop straw, weeds, leaves, peat, garbage and other waste, etc.) as the main raw material, mixed with human and livestock manure and urine. Because the composting materials, composting principle, and composition and properties of manure are similar to those of barnyard manure, it is also called artificial barnyar...
