Abstract
The invention relates to a soil conditioner, in particular to a soil conditioner specially used for alkali-resistant salt-inhibiting rice of saline-alkali land and a processing method thereof. The soil conditioner is characterized by comprising the materials based on the weight percentage: 45-55% of furfural slag, 17-20 % of weathered coal, 10-25% of straw powder and 10-15% of organic fertilizer. The processing method comprises: the furfural slag, the weathered coal, the organic fertilizer and the like are dried by air and have the water ratio being less than 10%; then, according to the formulation requirements for producing conditioners with different mixture ratios, all the materials are mixed and ground quantificationally according to the proportion and screened to lead the particle size to be reduced to below 2nm, and then the mixture is evenly mixed with the straw powder and the like and enters a double-roller extrusion type granulator to be extruded and shaped under the assistance of bonding agent; after that, the product is weighed for subpackage, treated by quality testing and sealed to leave factory; the invention can simultaneously neutralize soil alkaline, inhibit uprise of salt, improve physicochemical property of the soil and provide rich nutriment for crops.
Description
Technical field
The present invention relates to a kind of soil improvement agent, especially relate to a kind of improver special for alkaline land alkali-resistant salt-restricting rice and working method thereof.
Background technology
Salt and alkali component in the soil is too much, and the one, be unfavorable for that rice root absorbs moisture, thereby cause paddy rice dehydration, the underproduction, in addition dead; The 2nd, too much salt and alkali component can suppress soil microorganisms activity, nutrient between soil inside, soil and the paddy rice is transformed hindered, to have a strong impact on paddy growth.Using soil improvement agent is the novel method that is different from traditional soil improvement method that grows up on the basis of modernization industry, the soil improvement agent physicochemical character of can improving the soil to a certain extent, can increase the soil nutrient deposit, improve available nutrient, alleviate nutrient imbalance, can reduce soil pH value and specific conductivity simultaneously.Along with the widespread use of soil improvement agent in agricultural and ecotope, the product innovation of soil improvement agent is also more and more both at home and abroad.As notification number is that CN1377936A, denomination of invention are: utilize waste gypsum plate to produce the method and products thereof of saline-alkali soil conditioner and use, it is with the exchangeable sodium in the displacement of the calcium ion in the calcium sulfate soil, so it can only solve the too high problem of Na ion concentration, and the source of waste gypsum plate is also limited.In addition, the factor that the saltings is not suitable for plant growth is not only that exchangeable sodium in the soil is too much, also has features such as " sticking, plates, thin ", can obtain better effect so add effect such as some nutritive ingredients.Notification number is that CN1487052, denomination of invention are: soil salinization modifying agent, it also is the exchangeable sodium in the calcium sulfate displacement soil, also added a certain amount of macroelement and trace element in addition, but its main component terra alba and anhydrous calciumsulphate cost are higher, so be difficult for promoting.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of and can realize sweetening of the soil alkalescence simultaneously, suppress salinity and rise, improve the salt affected soil physicochemical character, a kind of alkaline land alkali-resistant salt-restricting rice special-purpose soil modifying agent of rich nutrient substances is provided for crop.
Another object of the present invention provides the working method of this alkaline land alkali-resistant salt-restricting rice special-purpose soil modifying agent.
The present invention realizes in the following way:
A kind of improver special for alkaline land alkali-resistant salt-restricting rice is characterized in that: it comprises following raw materials in percentage by weight: 45%-55% furfural dregs, 17%-20% weathered coal, 10%-25% straw powder and 10%-15% fertilizer;
Described weathered coal is the coal that is exposed to the face of land or is positioned at shallow surface;
The content of humic acid is greater than 30% in the described weathered coal;
Ash content in the described weathered coal is less than 15%;
Described straw powder is a stalk, grass powder;
Contain the zinc fertilizer that weight percentage is 1-3% in the described raw material, the zinc fertilizer main component is a zinc sulfate;
Contain the iron fertilizer that weight percentage is 1-3% in the described raw material, the main component of iron fertilizer is a ferrous sulfate;
The working method of described nutritive soil improver special for salt alkali land is that described furfural dregs, weathered coal, fertilizer is air-dry; make its water ratio less than 10%; then described furfural dregs, weathered coal, fertilizer are mixed by described weight percentage and pulverize; sieve; granularity is reduced to below the 2mm, after mixing with the straw powder of described weight percentage etc. again, enter in the pair roller extruding type tablets press extrusion molding under the assistance of tackiness agent; weighing packing is then sealed after the quality inspection and is dispatched from the factory.
The present invention has following effect:
When alkali-affected soil pH 〉=8.5, have in addition greater than 10, suppressed the growth of paddy rice to some extent.Modifying agent main raw material furfural dregs provided by the invention belongs to acid modifying agent, and its pH is 1.7～4.5, to a great extent sweetening of the soil basicity.Evidence, the application of the invention can make the ESP of intensity alkali-affected soil be reduced to below 15%, the pH value can be reduced to below 8.5, help the abundant absorption of rice root like this, also help the conversion of nutrient between rice root and the soil, make its growth not be subjected to the salt alkaline stress moisture.
Simultaneously, the main raw material furfural dregs and the weathered coal of modifying agent provided by the invention contain a large amount of humic acid materials, has stronger ion-exchange performance, surface adsorption performance and tactosol effect, the soil microaggregate is increased, improve physical propertiess such as the soil weight, porosity and soil compaction, Soil structure is rationalized, and effectively suppress the rising of salinity.By using this soil improvement agent, can make the unit weight of heavy salinized soil reduce by 0.2～0.5g/cm3, porosity increases by 3.2～8.6%.This all helps the growth of rice root and to nutrient absorbing.
In addition, in the soil improvement agent provided by the invention organic content greater than 22%, total nitrogen content greater than 0.25%, phosphorus content greater than 0.15%, potassium content is greater than 0.27%, makes soil break away from the bad characteristics of " thin ", makes paddy growth that competent nutrient be arranged.Simultaneously, paddy growth is responsive to zinc and iron, so this modifying agent has added trace element zinc and iron, can make rice yield improve 7～11% like this.
The present invention can realize sweetening of the soil alkalescence simultaneously, suppress that salinity rises, soil physico-chemical property improves, provide abundant nutrition material and working method simple for crop.
