Abstract

The invention discloses a mineral source biochar soil conditioner and a preparation method thereof, and the soil conditioner is prepared by mixing the following components in parts by weight: 2-10 parts of mineral source biochar, 5-15 parts of corn straw decomposed powder, 5-10 parts of a compound microbial agent, 0.1-0.3 part of potassium fulvate, 1-5 parts of acetic bacteria fermented corn flour liquid, 0.3-0.5 part of potato whole powder and 4-10 parts of pea meal. The mineral-derived biochar soil conditioner is prepared from mineral-derived biochar, decomposed corn straw powder, a compound microbial agent, potassium fulvate, acetic bacteria fermented corn flour liquid, potato whole powder and pea meal as main raw materials through a scientific process, and has three significant soil conditioning properties of water retention, fertility increasing and ventilation. The mineral-derived biochar soil conditioner has the advantages that the mineral-derived biochar soil conditioner is prepared from the mineral-derived biochar, the decomposed corn straw powder, the compound microbial agent, the potassium fulvate, the acetic bacteria fermented corn flour liquid, the potato whole powder and the pea meal; nitrogen, phosphorus and potassium in soil are mainly adsorbed through the adsorbability of the mineral source biochar, nitrogen, phosphorus and potassium are decomposed through the compound microbial agent, and nutritional ingredients are released, so that the effect of conditioning the soil is achieved, the conditions of soil fertility loss, poor physical and chemical properties and the like are effectively solved, and the problems of soil hardening and salinization are effectively solved.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a mineral source biochar soil conditioner, and the invention also relates to a preparation method of the soil conditioner. Background technique [0002] Mineral biochar is a large amount of black gray slag and organic matter produced after dry distillation and crushing of oil shale, and is a solid combustible organic mineral with high ash content. China's oil shale reserves reach 329.89×10 8 t, Correspondingly, the amount of biochar produced from mineral sources is large, but the development and utilization are insufficient. Mineral-derived biochar is porous in microscopic form, with abundant pores and a huge surface area, which can absorb 5 to 6 times its own weight of water; it can absorb cations and anions, and has a high ion exchange capacity; its unique physical and chemical properties enable it to Exchange and adsorb fertilizers and soil nutrients to improve soi...
