preparation example Construction

[0026] The invention provides a kind of preparation method of blasting biochar, comprising the following steps:

[0027] (1) Mechanically pulverize the tobacco stalk into 2-3cm;

[0028] (2) Place the pulverized tobacco rod in a steam blaster, heat it to 2.0-2.5MPa with 120-260°C saturated steam, and keep it for 5-10min;

[0029] (3) Rapid decompression to atmospheric pressure within 1 / 100s to achieve instantaneous blasting;

[0030] (4) After drying at 45-60°C, crush and sieve to prepare explosive biochar.

preparation example 1

[0032] The preparation method of explosive biochar comprises the following steps:

[0033] (1) mechanically pulverize the tobacco stalk into 2cm;

[0034] (2) Place the pulverized tobacco rod in a steam blaster, heat it to 2.0MPa with 120°C saturated steam, and keep it for 10min;

[0035] (3) Rapid decompression to atmospheric pressure within 1 / 100s to achieve instantaneous blasting;

[0036] (4) After drying at 45°C, crush and sieve to prepare explosive biochar P1.

[0037] The prepared explosive biochar P1 has a pH of 7.75, a total carbon content of 45.30%, a total nitrogen content of 2.35%, and a specific surface area of ​​1.47m 2 / g.

preparation example 2

[0039] The preparation method of explosive biochar comprises the following steps:

[0040] (1) mechanically pulverize the tobacco stalk into 3cm;

[0041] (2) Place the pulverized tobacco rod in a steam blaster, heat it to 2.5MPa with 260°C saturated steam, and keep it for 5min;

[0042] (3) Rapid decompression to atmospheric pressure within 1 / 100s to achieve instantaneous blasting;

[0043] (4) After drying at 60°C, crush and sieve to prepare explosive biochar P2.

[0044] The prepared explosive biochar P2 has a pH of 8.05, a total carbon content of 45.73%, a total nitrogen content of 2.50%, and a specific surface area of ​​1.64m 2 / g.

Abstract

The invention relates to a special tobacco fertilizer for improving the water retention capacity of tobacco planting soil. According to the technical scheme, on the basis of biomass charcoal, the water storage and moisture conservation capacity of soil is improved; by compounding polyacrylamide and zeolite, the moisture absorption capacity of the soil is improved; then N, P and K elements are supplemented through ammonium nitrate, monocalcium phosphate and potassium sulfate respectively; therefore, the purposes of efficiently utilizing limited water resources and improving the water retentioncapacity of tobacco planting soil are achieved.

Description

technical field [0001] The invention belongs to the technical field of tobacco planting, in particular to a special tobacco fertilizer for improving the water retention performance of tobacco planting soil. Background technique [0002] Soil moisture is the foundation of tobacco growth. The life activities of tobacco can only be carried out smoothly under the ecological conditions with suitable water. However, tobacco is mostly planted in mountainous and hilly areas. Due to the limitation of terrain conditions, the irrigation conditions are generally poor. When it is exposed to water, it will affect the metabolic activities of the tobacco plants, inhibit the growth and development, and seriously affect the yield and quality of tobacco leaves. Therefore, efficient use of limited water resources and improvement of soil water retention in tobacco planting are crucial for the sustainable development of high-quality tobacco leaves. [0003] Biochar is a solid product of bio-orga...
