Description
Technical field
The present invention relates to a kind of soil improvement agent, especially a kind of is the composite soil modifier of basic raw material with the coal dust, and the manufacture method of this soil improvement agent.
Background technology
Soil is made up of mineral substance, organic matter and microorganism three parts, is the basis of crop growthing development.Soil mineral is the main body of soil constitution, is the matrix of plant-growth, is again the main source of plant inorganic nutrients; Organic matter is fertilizer provision from soil, protects fertile important substance basis, is again the necessary composition that forms soil aggregate and keep soil from packing together; Soil fertility such as microorganism is the organism of living in the soil, and formation and decomposition, the nutrient that it participates in conversion, the soil ulmin of soil material and energy directly discharges, nitrogen is fixing form and growth course.Soil improvement agent is the active substance that adds in order to the shortage that solves some component in the soil, and soil improvement agent exists that water retention property is poor, kind is single, nutrient easily runs off, can't satisfy problems such as the long-acting fertility of requirement, soil of all kinds of soil and various crops is low at present.
Summary of the invention
The purpose of this invention is to provide problems such as a kind of composite soil modifier is poor in order to the product water retention property that solves prior art, kind is single, nutrient easily runs off, the long-acting fertility of soil is low.
Another object of the present invention provides the manufacture method of this composite soil modifier.
Composite soil modifier of the present invention, the weight proportion of raw material is as follows:
Coal dust 20～100
5～25 weight % highly basic or strong acid solution 150～300
Super strength water absorbent 1～10
In, micro-salt 0.007～0.01
The methyl alcohol immersion liquid 1～10 of 1: 3 cottonseed or boll hull
Starch 1～30
Composite fungus agent 0.001～0.007;
Coal dust is through highly basic or strong acid treatment post neutralization, filtrate and super strength water absorbent, in, the methyl alcohol immersion liquid of micro-salt and cottonseed or boll hull mixes, and adds the starch mixing of heating again, the cooling back adds composite fungus agent, drying-granulating forms.
Wherein coal dust is more than 200 orders, is selected from weathered coal, mud coal, peat composed of rotten mosses and brown coal; Highly basic is selected from sodium hydroxide and potassium hydroxide; Strong acid is selected from nitric acid, sulfuric acid, hydrochloric acid and phosphoric acid; Super strength water absorbent is selected from the commercially available prod, as the LPA-1 of u s company's production; Moderate-element is selected from silicon, copper and boron; Trace element is selected from zinc, iron and germanium, also can design according to the contained middle micro-situation of the regional soil of dispensing product of the present invention; The methyl alcohol immersion liquid of cottonseed or boll hull is cottonseed or boll hull and methyl alcohol by weight 1: 3 leaching liquid; Starch is selected from W-Gum, potato starch; The trade name of composite fungus agent is a Fu Er phosphorus potassium microbial inoculum, be that Beijing Shuanglong Ams Science ﹠ Technology Co., Ltd. produces, its Ministry of Agriculture's registration card is: microorganism fertilizer (2002) faces word (0201) number, and it includes silicate bacteria, thiobacillus, pseudomonas, root nodule bacterium, genus bacillus, Arthrobacter.
The humic acid that coal dust in the composite soil modifier raw material of the present invention generates through reaction, sulfenyl salt provide suitable nutrient for all kinds of soil and crop.Contain the super strength water absorbent of some amount in the raw material, thereby strengthened the water retaining function of product.In having added in the raw material, trace element, can increase various nutrients in the soil.Gossypol in cottonseed or the immersion liquid of boll hull methyl alcohol in the soil, trace element has chelating, adsorption and enrichment effect, can prevent that nutrient runs off because of drip washing.A considerable amount of microbial spores have been thrown in the raw material of the present invention, they are respectively silicate bacteria, thiobacillus, pseudomonas, root nodule bacterium, genus bacillus, Arthrobacter, potassium in order to potassium felspar sand sand grains in offices and men's earth is peeled off out, the required ion sulphur of plant is made in nutrition with sulfenyl, absorb the nitrogen in air and the soil, too much deleterious salt, alkali in the soil are converted into other form materials that plant can be born, macromolecular material in the soil improvement agent is degraded, thereby improved the long-acting fertility of soil.
Composite soil modifier manufacture method of the present invention comprises the steps:
(1) in coal dust, adds highly basic or strong acid solution, stirred 5～40 minutes, soak reaction 2～48 hours, filter;
(2) filtrate is concentrated into original volume 1/2～1/5, adds the neutralization of acid or alkali, filters, and is cooled to below 60 ℃;
(3) add super strength water absorbent, in, the methyl alcohol immersion liquid of micro-salt, cottonseed or boll hull, stirring reaction 2～8 hours;
(4) starch is put into mixed solution, heat 40～100 ℃, mixing postcooling to 20～30 ℃ are put into composite fungus agent wherein mixing, granulation.
Method of the present invention obtains coal dust more than coal dust can being broken to 200 orders, or directly adopts commercially available coal dust.
Method of the present invention can be measured the content of humic acid in the coal earlier, to determine strong acid or alkaline consumption.
Method of the present invention can be with below the granulating and drying temperature control to 40 ℃, and dry granular moisture content is controlled in 10%, and the upright footpath of grain is in 3mm.The product pack can be sealed after the granulation.
Compared with prior art, the present invention has following advantage:
1. product of the present invention contains the super strength water absorbent of some amount, and stronger water retaining function mainly solves the problem that arid area lack of water and plant are kept normal growth; The soil that annual rainfall is 150 millimeters in theory every mu can accept 66 tons of water, if there is 50% rainwater to be absorbed by product of the present invention, then but retaining is 33 tons, product of the present invention will be under 25～30 ℃ of temperature after the suction slow release 150 days, this keeps normal growth and is absolutely necessary for those high temperature, dry regional plant, and accomplish this point, need only be 33 kilograms of every mu of ground dispensing products of the present invention just.
2. product of the present invention contains the sequestrant of some amount, it in the soil, trace element has chelating, absorption, inrichment, prevents that nutrient runs off because of drip washing.
The present invention utilize coal through reaction generate humic acid, sulfenyl salt, can improve the crumb structure of soil, improve the fertility of soil; Because of humic acid has stronger ion-exchange capacity and adsorption, positively charged ion in the soil and negatively charged ion are had very strong exchange capacity, kept the acid base equilibrium in the soil, increase the surge capability of soil, improvement acid soil and saltings.
4. having thrown in a considerable amount of microbial spores in the product of the present invention, increased the activity of soil, reduced the fertilizer amount in farmland, kept soil from packing together, promoted the benign cycle of soil fertility, is the composite biological fertilizer that " green food " produced.
