Embodiment 1

[0044] A preparation method of acidic soil conditioner for tea gardens, comprising the steps of:

[0045] 20 parts of dolomite powder, 60 parts of modified biochar, 10 parts of humic acid, 10 parts of vermicompost, and 10 parts of pig manure were stirred and mixed, and then dried to obtain a mixture; then 12 parts of compound bacteria agent, 8 parts of Parts of dicyandiamide and 15 parts of lignin-based superabsorbent resin are added to the mixture, and the soil conditioner is obtained after mixing evenly.

[0046] Wherein, the preparation method of described modified biochar comprises the following steps:

[0047] (1) washing the tea branches, drying and pulverizing to obtain granular raw materials, and then keeping the granular raw materials at 800°C for 2 hours under a nitrogen atmosphere, and taking them out after cooling to obtain biochar;

[0048] (2) Add the biochar (80 parts) obtained in step (1) into 400 parts of 2mol / L NaOH solution, mix and stir for 1 hour, then ad...

Embodiment 2

[0057] A preparation method of acidic soil conditioner for tea gardens, comprising the steps of:

[0058] 10 parts of dolomite powder, 40 parts of modified biochar, 5 parts of humic acid, 5 parts of vermicompost, and 5 parts of cow dung were stirred and mixed, and then dried to obtain a mixture; One part of 3,4-dimethylpyrazole phosphate and 10 parts of lignin-based superabsorbent resin are added to the mixture, and the soil conditioner is obtained after uniform mixing.

[0059] Wherein, the preparation method of described modified biochar comprises the following steps:

[0060] (1) washing, drying and pulverizing the distiller's grains to obtain granular raw materials, and then keeping the granular raw materials at 700° C. for 4 hours under a nitrogen atmosphere, and taking them out after cooling to obtain biochar;

[0061] (2) Add the biochar (40 parts) obtained in step (1) into 200 parts of 2 mol / L NaOH solution, mix and stir for 3 hours, then add 10 parts of chitosan, and...

Embodiment 3

[0070] A preparation method of acidic soil conditioner for tea gardens, comprising the steps of:

[0071] 15 parts of dolomite powder, 50 parts of modified biochar, 8 parts of humic acid, 8 parts of vermicompost, and 8 parts of chicken manure were stirred and mixed, and then dried to obtain the mixture; Add 1 part of 2-chloro-6-(trichloromethyl)pyridine and 12 parts of lignin-based superabsorbent resin into the mixture, and mix well to obtain the soil conditioner.

[0072] Wherein, the preparation method of described modified biochar comprises the following steps:

[0073] (1) washing the tobacco stalks, drying and pulverizing them to obtain granular raw materials, and then keeping the granular raw materials at 750° C. for 3 hours under a nitrogen atmosphere, and taking them out after cooling to obtain biochar;

[0074] (2) Add the biochar (60 parts) obtained in step (1) into 300 parts of 2mol / L NaOH solution, mix and stir for 2 hours, then add 12 parts of chitosan, and condu...

Abstract

The invention discloses a tea garden acidic soil conditioner and an improvement process, and the soil conditioner is prepared from the following raw materials in parts by weight: 10-20 parts of dolomite powder, 40-60 parts of modified biochar, 5-10 parts of humic acid, 5-10 parts of wormcast, 5-10 parts of an organic fertilizer, 6-12 parts of a complex microbial inoculant, 3-8 parts of a nitrification inhibitor and 10-15 parts of lignin super absorbent resin. The soil conditioner can effectively improve the fertility of soil, solve the problem of insufficient water retention capacity of the soil, and inhibit the reduction of the soil base saturation; meanwhile, through the soil improvement process provided by the invention, soil acidification can be further relieved, and the soil microenvironment of the root microcell can be improved, so that the tea quality is improved.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to an acidic soil improver for tea gardens and an improvement process. Background technique [0002] Soil pH is considered to be the most critical indicator in soil because it directly affects the growth of plants. Soil acidification can negatively affect the sustainability of agricultural systems. Tea tree is an important economic crop in subtropical regions and is deeply loved by local farmers. As a special crop, tea tree likes acidic soil, and the pH value of the soil is generally required to be in the range of 4.0-6.5. Soil pH affects the growth and development of tea trees, and the growth and development of tea trees affects the change of soil pH. Soil roots secrete various organic acids in their metabolism, which is one of the reasons for the acidification of tea garden soil. Soil acidification will gradually deepen with the growth of planting years. St...
