Description

A kind ofly carbonize environment-friendly fertilizer that stalk is combined with biogas waste residue and preparation method thereof

Technical field

The invention belongs to the Technology field of fertilizer, be specifically related to a kind ofly carbonize environment-friendly fertilizer that stalk is combined with biogas waste residue and preparation method thereof.

Background technology

Peasant grabs farming season to rob, crop straw burning of having to, and crop straw burning pollutes the Sustainable development having had influence on Chinese agriculture and national economy, becomes serious socioeconomic problem and the hidden danger of traffic accident.Straw charring is by stalk drying or dries, pulverizes, and then in equipment for preparing charcoal, the operations such as drying, destructive distillation, cooling, make the process of charcoal by loose stalk.Due to the core process that destructive distillation is straw charring, so also have people with stalk destructive distillation acute pyogenic infection of finger tip straw charring, the charcoal produced by straw charring can be described as straw charcoal or straw charcoal.Because straw charring is different from traditional charcoal method, it take mechanical workout as Main Means, and thus straw charcoal is otherwise known as machine-processed straw charcoal or machine-made charcoal.Because straw charring has expanded the raw material sources of charcoal production, so there is people that the charcoal produced by mechanical destructive distillation for raw material with the biomass such as stalk, timber is referred to as biomass charcoal, referred to as charcoal.

Gac a kind ofly has special microlitic structure, flourishing nanometer level microporous, specific surface area up to 1000m ^2Hthe good adsorbent of/more than g and catalyzer, by the widespread use of each field.

Compound manure can provide most nutriment of plant-growth, be basic three large key elements mixing stone flours or organic tunning with N, P, K be that basic bed material produces, be widely used in the cultivation of various farm crop, essential, and more and more trend towards industrialization along with agricultural, fertilizer abuse and irrational use, not only contaminate environment, more cause the unnecessary wasting of resources, against the theory of Sustainable development.

Fertilizer of the present invention will accomplish Rational Application, become the fertilizer with certain slow release effect essential, fertilizer is splashed to crop surface, with slowly cracking after making moist, the effect nutritive element of release the inside, coating is conducive to the speed of fertilizer cracking, be unlikely to immediately pulverizing and cause leakage, the coating agent of stone flour of simultaneously adulterating can prevent from luming because making moist between fertilizer, the gac that simultaneously inner charing stalk obtains has the ability of absorption nutritive element, be unlikely to run off too fast with current, save fertilizer, increase operation rate, utilize stalk for raw material simultaneously, not only alleviating energy crisis, more protection of the environment.
