CN106045755A - High-efficiency natural mineral soil conditioner and preparation method thereof - Google Patents

Abstract

The invention discloses a high-efficiency natural mineral soil conditioner and a preparation method thereof. The soil conditioner is prepared from the following raw materials in parts by weight: waste dried wood, a 6-10% dilute sulfuric acid solution, a 3-5 mmol/g sodium sulfite solution, glauconite, chitin, forsterite, bamboo charcoal, Chinese herbal medicine powder, candy pomace, actinolite, humic acid powder, peat, chinaberry bark, wormwood straws, bamboo fibers, an azotobacter microbial inoculant, vermiculite and a proper amount of water. The treated natural-mineral-rich stones can not supply nutrients to crops instantly, but can stably supply nutrients for a long time. After the stones are calcined, the metal cations contained in the stones are cracked into oxides, the oxides are further cracked in the hardening process and enter the soil; as time goes on, ions are gradually formed; and the ions belongs to natural minerals without any side effect, thereby further protecting the soil structure.

Description

A kind of efficient natural mineral soil conditioner and preparation method thereof

Technical field

The invention belongs to the Technology field of plantation, be specifically related to a kind of efficient natural mineral soil conditioner and Preparation method.

Background technology

Lignin is the macromolecular compound by the link of polytype key, key of different nature, different merits Can be connected on construction unit cause the difference of the chemical property of lignin structure unit by base, therefore, each in lignin macromole The chemical reactivity at position is inhomogenous.

The ins and outs that lignin has are that the C5 on the phenyl ring in structure does not has substituent group, i.e. likely react on phenyl ring The free room (ortho para of phenolic hydroxyl group) of crosslinking, can further crosslinking curing, thus time lignin there is glued spy Property, its structure make lignin have stronger sequestering and colloidal property, no containing a certain amount of phenolic hydroxyl group and carboxyl etc. Only such, substantial amounts of phenolic hydroxyl group, carboxyl and carbonyl, relatively low dissolubility, and the existence of different oxygen-containing group makes wooden Element has adsorptivity, is especially suitable for doing adsorbent and uses.

Lignosulfonates produce in sulfurous method or modified sulphite pulping process, the conduct of lignin own Flocculant effect is not ideal enough, and current lignin flocculant mainly includes cationic, anionic and amphoteric flocculant etc. Three classes, and sulfonic group modified on xylonic acid can be with Liquidity limit and heavy metal ion.

One of reason of soil compaction is exactly long-term chemical fertilizer application, and farm manure deficiency causes the organic decline of soil, Humus can not be supplemented timely, causes hardening and chapping of soil, chemical fertilizer apply so that soil alkalescence enhancing, micro- Biology is killed, and causes the activity reduction of microorganism, and easily and negative root ion forms slightly solubility for the calcium in soil, magnesium plasma Inorganic salt, destroys soil granular mechanism, and the potassium ion displacement performance in potash fertilizer is strong, has replaced the polyvalent cation in soil, And itself not there is key bridge effect, and destroy the crumb structure of soil, reducing use chemical fertilizer is also to reduce soil compaction, changes One big method of kind environment.

Summary of the invention

According to the relevant knowledge in background technology, the invention reside in and industrial waste wood is used, through processing Afterwards, for the protection of soil, have keep soil from packing together, Liquidity limit and the effect of heavy metal ion, simultaneously from figure The micelle characteristic become is conducive to the rooting development of crop:

A kind of efficient natural mineral soil conditioner, it is characterised in that be made up of the raw material of following weight portion: discarded seasoned wood 30 ~ 40,6 ~ 10% dilution heat of sulfuric acid 25 ~ 30,3 ~ 5mmol/g sodium sulfite solution 100 ~ 120, glauconite 20 ~ 30, forsterite 25 ~ 35, bamboo charcoal 6 ~ 10, herbal powder 20 ~ 28, sugar slag 10 ~ 16, Actinolitum 6 ~ 10, humic acid powder 3 ~ 6, peat 14 ~ 20, neem bark 12 ~ 18, Folium Artemisiae Argyi straw 30 ~ 35, bamboo fibre 5 ~ 8, nitrogen-fixing bacteria microbial inoculum microbial inoculum 1 ~ 2, Vermiculitum 12 ~ 16 and appropriate water；

The preparation method of a kind of efficient natural mineral soil conditioner, it is characterised in that include following step:

(1) by discarded seasoned wood through pulverizing, selecting crude drugs with winnower goes out the granule of grain of rice size, by wooden of 6 ~ 10% dilution heat of sulfuric acid moistening The surface of grain, naturally blots rear secondary moistening, continuously wetting 3 ~ 5 times, naturally dries under room temperature；

(2) (1) gained wood substance grain deionized water soaked filtration 2 ~ 3 times and be vacuum dried, joining 3 ~ 5mmol/g sulfurous In acid sodium solution, processing 1.5 ~ 2.0h under the conditions of microwave 600 ~ 800W, process is incubated, and finally washing after drying obtain modified Wood substance grain；

(3) mixing glauconite, forsterite, Vermiculitum and Actinolitum, is placed in rotary kiln high temperature 1000 ~ 1200 DEG C calcining 40 ~ 50min Obtaining grog, then a small amount of the most repeatedly trickle carries out hardening, and crushing grinding becomes powder；

(4) mixing neem bark, Folium Artemisiae Argyi straw and other following residual components being not directed to, add water for ball milling and become homogenate, then in 200 ~ 250 DEG C of drying, add the modified wood substance grain described in bamboo charcoal, bamboo fibre, (2) and (3) gained powder, mix.

Timber is made up of cellulose and lignin two parts mostly, and invention thinking is to utilize acid-precipitation method to obtain alkali lignin to become Point, before this industrial waste wood was pulverized and cut, and obtained granular timber, be then dried, then soak At certain density dilution heat of sulfuric acid, (sulfuric acid solution can hydrolyze the cellulose in timber to stain, makes polysaccharose substance, sugar Class is dissolved with current, comes off from timber, and the existence that lignin portion is relatively stable, form distinct framing structure, fiber The part that element dissolves leaves hole, increases specific surface area and exposes lignin portion, and the amount of appropriate control acid adding can be suitable Retain a certain amount of cellulose, the beneficially stability of particle space structure), use and be dried Hydrolyze method, treat that dilute sulfuric acid moistening is done When wood substance grain about 70 ~ 80%, pull out and be dried, both can guarantee that acid solution permeates uniformly, simultaneously the change of controlled quentity controlled variable, On the one hand cellulose consumes too much, causes wood substance grain loosely organized, also at gelled acid solution when wood substance grain is dried when, After concentration reaches to a certain degree, cellulose limit starts profit and rises, cell wall rupture, cellulose dissolution, percent hydrolysis be up to 90% with On.

The wood particle obtained now becomes the granule of a kind of porous, mostly exposes lignin component in aperture simultaneously, At this moment add to certain density sodium sulfite solution, react under certain temperature conditions, can be by pore interior Lignin portion carries out sulfonation, becomes xylonic acid sulfonate component, and the microwave of invention employing 600 ~ 800W is as condition, microwave one Aspect can promote temperature and meet reaction condition, and microwave vibrations simultaneously can promote that solution penetrates into hole, reduces liquid table The impact of surface tension.

Beneficial effects of the present invention: the building stones that will be enriched in natural minerals in invention process, although can not be instant carry For crop nutrition content, but nutrient can be supplied steadily in the long term, through calcining make containing metal cation be cracked into oxide, Crack further during hardening, enter passage in time after soil, gradually form ionic forms, this belong to natural Mineral, have no side effect, further soil protection structure.
