Problems solved by technology

The following problems still exist in the process of preparation and application of organic fertilizers: 1. There is no strict control of size, particle size, carbon-nitrogen ratio, temperature, and moisture content, which makes the parameters and component content of biomass organic fertilizers fluctuate widely. , the quality is unstable; 2. Only the supply of main nutrients such as nitrogen fertilizer, phosphorus fertilizer, and potassium fertilizer is considered, and other nutrients and trace elements that can improve soil fertility and functions are not considered, and the ingredients cannot be made through scientific and reasonable processes. There is a synergistic effect between them, and the improvement of the rooting, transplanting, and growth capabilities of trees and crops needs to be improved; 3. During the application process, it is usually necessary to mix it with a large amount of decomposed manure before applying it, which will increase the heavy metal content in the soil. The method is harmful to the soil, trees and crops, and it is necessary to study a method of applying organic fertilizers with little harm and a wide application range.

Embodiment 1

[0035] The present embodiment provides a kind of biomass-based organic fertilizer preparation process, comprising the following steps:

[0036] S1. Mixing: In parts by weight, take 16 parts of walnut kernel skin, 29 parts of grape skin, 7 parts of peat moss, and 46 parts of straw, and mix and stir evenly to obtain the mixture a; the straw is made of corn stalk and wheat straw according to the mass ratio of 1 :2 mixed. The walnut kernel skin needs to be pretreated. The specific process is: soak the walnut kernel skin in clean water, air-dry and crush it into powder, put it into a vacuum dryer, heat it up to 115°C under a negative pressure of -10KPa, and dry it for 1.2 Hours; when the temperature is lowered to 46°C, the material is discharged, and sieved to obtain particles with a particle size of 60-80 mesh.

Abstract

The invention discloses a biomass-based organic fertilizer preparation technology and an application method. The preparation technology comprises the following steps: mixing, expansion and activation,hydrothermal carbonization, fermentation and granulation. Technological parameters such as moisture, temperature, etc. are strictly controlled such that the wrapping effect of peat moss and straw onwalnut kernel shell and grape skin substances is strengthened, and macromolecular carbon chains in the molecules are also cracked into small-molecular carbon under the impact of high-pressure nitrogen. The product of the invention has fertilizer impartiality, contains rich elements, is long-acting and efficient, and has a good synergistic effect with soil. According to the application method, fourfertilization methods including seedling transplantation, hole fertilization of a base fertilizer, spraying of leaf surface and seedbed fertilization are selected. Organic content of the organic fertilizer of the invention reaches 46.2%, total nutrient content reaches 5.7%, number of fecal coliforms is 18 / g, and mortality of ascarid eggs is 98.7%. By applying the organic fertilizer to fertilization of fruit trees, fruiting season is advanced for 15 days, the maturation period is advanced for 17 days, and the yield growth rate reaches 8.4%.

Description

technical field [0001] The invention relates to the technical field of biomass organic fertilizers, in particular to a preparation process and application method of biomass-based organic fertilizers. Background technique [0002] In the production process of biomass organic fertilizer, the raw materials can be selected from various livestock and poultry manure and various wastes, and the content of the basic formula varies with different types and equipment. Micro-ecological theory believes that inoculation of a large number of beneficial microorganisms and the rhizosphere of crops may play a comprehensive role in regulating ecological balance; plant growth-promoting rhizosphere bacteria theory believes that inoculation of a large number of beneficial bacteria in the roots of crops can promote growth is the result of comprehensive effects , is not a single action of nitrogen fixation, phosphorus solubilization, potassium solubilization, inhibition of pathogenic bacteria, or ...
