Embodiment 1

[0012] A preparation method suitable for harmful microorganism soil conditioner, comprising the following steps:

[0013] 1) Preparation of modified biochar: Roast shell powder under oxygen-limited conditions, and the temperature of calcination is 120℃ for 6min; 200℃ for 12min; 400℃ for 10min; 620℃ for 100min; 400℃ for 45min; 200℃ Calcining for 25 minutes; calcination at 100°C for 40 minutes; shell powder contains 2% zinc borate, 3% magnesium hydroxide and 0.1% manganese acetate. The calcined shell powder was naturally cooled in a dry environment, modified by adding 12% hydrochloric acid solution, reacted at 70°C for 2.4 hours, centrifuged to collect the precipitate, washed with water until neutral, and dried to obtain modified biochar. The above modified biochars are sufficiently magnetic and rich in H + The surface of activated carbon is rich in active functional groups such as carboxyl groups and phenolic hydroxyl groups. These functional groups can enhance the adsorption ...

Embodiment 2

[0017] A most preferred preparation method for harmful microorganism soil conditioner, comprising the following steps:

[0018] 1) Preparation of modified biochar: Roast shell powder under oxygen-limited conditions, and the temperature of calcination is 100℃ for 7min; 210℃ for 10min; 410℃ for 10min; 610℃ for 100min; 410℃ for 40min; 200℃ Calcining for 25 minutes; calcination at 100°C for 40 minutes; shell powder contains 1% zinc borate, 2% magnesium hydroxide and 0.3% manganese acetate. The roasted shell powder was naturally cooled in a dry environment, modified by adding 12% hydrochloric acid solution, reacted at 68°C for 2.5 hours, centrifuged to collect the precipitate, washed with water until neutral, and dried to obtain modified biochar. The above modified biochars are sufficiently magnetic and rich in H + The surface of activated carbon is rich in active functional groups such as carboxyl groups and phenolic hydroxyl groups. These functional groups can enhance the adsorp...

Embodiment 3

[0022] A preparation method suitable for harmful microorganism soil conditioner, comprising the following steps:

[0023] 1) Preparation of modified biochar: shell powder was roasted under oxygen-limited conditions, and the roasting temperature was changed as 120°C for 6 minutes; 200°C for 12 minutes; 400°C for 10 minutes; 600°C for 120 minutes; 400°C for 45 minutes; 210°C Calcining for 20 minutes; calcination at 100°C for 40 minutes; shell powder contains 2% zinc borate, 3% magnesium hydroxide and 0.1% manganese acetate. The calcined shell powder was naturally cooled in a dry environment, modified by adding 12% hydrochloric acid solution, reacted at 70°C for 2.4 hours, centrifuged to collect the precipitate, washed with water until neutral, and dried to obtain modified biochar. The above modified biochars are sufficiently magnetic and rich in H + The surface of activated carbon is rich in active functional groups such as carboxyl groups and phenolic hydroxyl groups. These fu...

Abstract

The invention discloses a preparation method of a soil conditioner applicable to harmful microorganisms. The preparation method comprises the following steps: uniformly mixing 50 to 70 parts of modified biological charcoal, 10 to 20 parts of a fermentation solution and 1 to 3 parts of waterborne acrylic resin and drying to obtain the soil conditioner. The preparation method disclosed by the invention has the beneficial effects that all components in the conditioner have a mutual effect and the variety of bacteria in treated soil is relatively abundant; the relative abundance of acidobacteria is remarkably increased and the relative abundance of proteobacteria is reduced; the relative abundance of GAL15 and AD-3 is remarkably reduced and the relative abundance of chloroflexi, verrucomicrobia and gemmatimonadetes is remarkably increased; the relative abundance of planctomycetaceae is remarkably increased and the relative abundance of bacteroidetes is remarkably increased; the micro-ecology of the soil is improved and the occurrence probability of root diseases of plants is reduced.
