Embodiment Construction

[0013] Specific embodiments of the present invention will be described below.

[0014] A method for preparing and using a soil conditioner, comprising the following steps: (1) placing the bamboo outside for 5 to 7 days, and then stacking it in an earthen kiln. The earth kiln is heated from the kiln mouth by direct heating of fuel (wood), and the heat generated rises to the top of the kiln and diffuses into the kiln; (2) Control the temperature inside the earth kiln at 60°C to 100°C, Part of the bamboo in the bottom layer is used to generate flue gas in the earth kiln, and the bamboo put into the earth kiln is pre-dried for 3 to 5 days by smoking to remove volatile substances; (3) the earth kiln The temperature is controlled at 100°C to 150°C, and the bamboo is dried for 5 to 7 days; (4) The temperature in the kiln is controlled at 150°C to 270°C, and the bamboo is pre-carbonized for 5 to 7 days; (5) The temperature in the kiln is controlled at 270°C to 450°C, and the bamboo i...

Abstract

The invention discloses a preparation and use method of a soil conditioner, and relates to the field of soil improvement. The method comprises the following steps that bamboos are piled in an earth kiln to be heated; (2) the bamboos are subjected to smoking pre-drying treatment for 3 to 5 days; (3) the bamboos are subjected to drying treatment for 5 to 7 days; (4) the bamboos are subjected to pre-carbonization treatment for 5 to 7 days; (5) the bamboos are subjected to carbonization treatment for 5 to 7 days; (6) the bamboos are subjected to calcining treatment for 5 to 7 days; (7) bamboo charcoal obtained through calcining in the step (6) is taken out of the kiln and is smashed into bamboo charcoal powder with the diameter being smaller than 3mm; the bamboo charcoal powder and the soil are mixed according to a mass ratio of 1 to 15. The method has the beneficial effects that pure natural bamboos are used as raw materials; no any additives and lyotropic matters are contained; the prepared soil conditioner is a green environment-friendly product without corrosion, toxicity or public hazards; the water absorption, water retention and fertilizer maintenance performance of the soil can be enhanced; the PH value of the soil can be changed; meanwhile, the performance price ratio is high.

Description

technical field [0001] The invention relates to the field of soil improvement, in particular to a method for preparing and using a soil improver. Background technique [0002] Soil improvement is a common means of soil reuse. The existing soil improvement method is to add soil conditioner to the soil to change the relevant parameters of the soil. However, most of the existing soil improvers contain chemical additives, which are likely to bring other types of damage or pollution to the soil. Therefore need to produce a kind of pure natural harmless soil conditioner. Contents of the invention [0003] The invention provides a method for preparing and using a soil conditioner, aiming at solving the disadvantage that the existing soil conditioner contains many chemical additives and easily causes other damage or pollution to the soil. [0004] The present invention adopts following technical scheme: [0005] A method for preparing and using a soil conditioner, comprising th...
