Abstract
The invention relates to a soil conditioner, in particular to a soil conditioner specially used for sunflower of solonetzic soil. The soil conditioner is characterized by comprising the materials based on the weight percentage: 35-55% of desulfurization waste, 20-25% of furfural slag, 10-25% of organic fertilizer, 5-15 % of weathered coal and 10-15% of other components. A processing method of the soil conditioner 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 desulfurization waste and other components 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, and is environment-friendly and economical.
Description
Technical field
The present invention relates to a kind of alkali-affected soil modifying agent, especially relate to a kind of special improver for alkaline soil alkalinity reducing salt-restricting sunflower.
Background technology
The growth of exchangeable sodium harm Sunflower Receptacle in the alkali-affected soil.Reason is: the one, and the hydrolysis of exchangeable sodium produces carbonate, hydrocarbonate and the organic acid salt of a large amount of sodium, improves the pH value of the soil solution.In the ordinary course of things, saltiness is low more in the alkaline earth, and the hydrolytic action Shaoxing opera of this sodium is strong, and pH is also high more, has intensive alkalescence, and the effect of corrosion Sunflower Root is arranged.The solubleness of some nutritive element is reduced, can not satisfy the needs of Sunflower Receptacle.On the other hand, alkali-affected soil is under the influence of sodium ion, and the colloid high dispersing has worsened soil physical, and mire is waterproof when wet, and the face of land forms hard soil crust when doing, and influences that crop emerges and root elongation, thereby need be improved.Simultaneously, the fertility of alkali-affected soil is also very low.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: method of utilizing waste gypsum plate production saline-alkali soil conditioner and products thereof is saline soil with application, notification number for CN1487052A, denomination of invention, these technology all are the exchangeable sodiums that adopt in the calcium sulfate displacement soil, but its raw material sources are less or cost is higher, are affected so promote.Because it is that soil hardens easily that alkali-affected soil influences another major cause of crop, and simple chemical amendments can not improve the situation of hardening, therefore also need add the organic or inorganic material that improves Soil structure, add the trace element that helps plant growth but lack in the soil again, improved effect is better.
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, improve soil physical and chemical property and provide rich nutrient substances, environmental protection, economic alkali-affected soil Sunflower Receptacle special-purpose soil modifying agent and working method thereof for crop.
The present invention realizes in the following way:
A kind of special improver for alkaline soil alkalinity reducing salt-restricting sunflower is characterized in that: it comprises following raw materials in percentage by weight: other component of 35%-55% desulfurization waste, 20%-25% furfural dregs, 10%-25% fertilizer, 5%-15% weathered coal and 10-15%;
Described desulfurization waste is a flue gas desulfurization waste of fire coal;
The major ingredient of described desulfurization waste is CaSO
42HzO;
Described weathered coal is the coal that is exposed to the face of land or is positioned at shallow surface;
Described weathered coal content of humic acid is greater than 30%;
Described weathered coal ash content is less than 15%;
Described other component is sodium humate and boron fertilizer or zinc fertilizer, and the main component of boron fertilizer is a borax, and the main component of zinc fertilizer is a zinc sulfate;
The working method of described a kind of special improver for alkaline soil alkalinity reducing salt-restricting sunflower is: furfural dregs, weathered coal, fertilizer is air-dry; make its water ratio less than 10%; then various raw materials are mixed by above-mentioned weight percentage and pulverize; sieve; granularity is reduced to below the 2mm, after mixing with desulfurization waste, other component of described weight percentage 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
1) reduces soil pH value and ESP
Calcium ion in the desulfurization waste can be replaced the sodium ion in the soil, reduces the content of exchangeable sodium, and utilizes acid modifying agent, and furfural dregs pH 1.7～4.5 can reduce the ESP of soil, thereby improves the physicochemical character of soil.Wherein furfural dregs and weathered coal have bigger total surface area, can also strengthen the surge capability of soil to alkali like this.
The soil improvement agent that the application of the invention provides can make the ESP of intensity alkaline earth be reduced to below 13%, and the pH value can be reduced to below 8.5.Soil alkalescence reduces like this, the corrosion of Sunflower Root is weakened greatly, and help root system to moisture and nutrient absorbing.
2) improve Soil structure
By using this soil improvement agent, can make the unit weight of intensity alkali-affected soil reduce by 0.2～0.5g/cm3, porosity increases by 3.2～10.6%, has improved the permeability of soil, makes Sunflower Receptacle root system normal growth.
3) reduce rate of fertilizer, comprehensive, rich nutrient substances are provided
Fertilizer utilization ratio improves about 15% than the utilization ratio of common chemical fertilizer.And the invention provides great number of organic matters, nitrogen, phosphorus and potassium, guarantee that the Sunflower Receptacle growth has enough nutrients to absorb.
4) increase the responsive trace element of crop
Sunflower Receptacle is a happiness boron crop, and alkali-affected soil major part boron deficiency not only also lacks zinc, so this modifying agent has added boron fertilizer and zinc fertilizer, can make output improve 3～8%.
5) abundant, the environmental protection of raw material sources
The present invention is a main raw material with desulfurization waste, furfural dregs, fertilizer and stalk, and these all are agriculture and industry wastes, and the source is abundant, has reduced its pollution to environment, has improved alkali-affected soil again simultaneously, thereby has improved ecotope.
