Abstract
The present invention is one kind of soil nutrient amendment and its preparation process. The soil nutrient amendment consists of turf, humate, botanical water retainer, trace elements, etc. in the weight proportion properly altered based on the soils and/or crops. It may be prepared into different forms, powder, pellet, etc. It has integrated functions of improving soil structure, nourishing, saving water and reducing pesticide consumption.
Description
Technical field
The invention belongs to soil fertility amendment and preparation method thereof, be specifically related to a kind of soil fertility amendment of forming by peat, sapropel, humic acids, big moderate-element and biomass water-holding agent.
Background technology
Fertility such as desertification, desertification, degeneration are low in order to improve, the soil type of unreasonable structure, and various soil improvement agents are developed and developed in countries in the world.
According to the type of improving the soil, soil improvement agent is divided into coventional type and tailored version.The former means the modifying agent that is applicable to multiple soil type; The latter refers to be specially adapted for a certain class or a certain geographic soil, has very strong specific aim.
According to the employed raw material of improving the soil, soil improvement agent can also be divided into inorganic type, organic type and organic-inorganic composite.Inorganic type means various inorganic fertilizers of simple use or various inorganic material, carries out soil improvement as Attapulgite, wilkinite, zeolite etc.; Organic type refers to use various organic materialss merely, as poultry manure, peat, wood chip, cotton seed hulls, straw, castor seeds etc.; Organic-inorganic composite refers to the soil improvement agent that organism and inorganic material are used.
The soil improvement agent of tailored version development at present is very fast.For the improvement of lean soil such as desertification, desertification, a kind of soil fertility amendment that utilizes of Xinjiang Inst. of Ecology and Geography, Chinese Academy of Sciences's invention.Said preparation is characterised in that and includes following composition by weight: 250 to 500 parts the peat composed of rotten mosses or weathered coal, 100 to 500 parts barnyard manure, 5 to 20 parts urea, 2 to 5 parts threeflod calcium superphosphate fertilizer, 0 to 10 part calcium bentonite or saponite or zeolite or vermiculite, 0 to 15 part black alum or ferrous sulfate, 0 to 5 part vitriolate of tartar, 0.5 to 1.5 parts zinc sulfate, 0.05 to 0.2 part ammonium molybdate, 0.17 to 0.5 part boric acid.It is a kind of composite organic-inorganic fertilizer, is again the compound soil improvement agent of a kind of organic-inorganic, is mainly used in improvement sandy soil, desert soil.This soil fertility amendment has been obtained certain effect on western desert soil, desert soil, but said preparation is for water supply in desert soil, the desert soil with for the hormesis effect of crop shortcoming.
Summary of the invention
The object of the present invention is to provide a kind of integrate improve the soil, nutrition, stimulation and the composite efficient degradable soil modifying agent of economizing on water and preparation method thereof.It is the compound soil improvement agent of a kind of organic-inorganic, is again a kind of composite organic-inorganic fertilizer.Be mainly used in desertification, desertification, degeneration and the dead soil improvement.
Be used to realize the composite efficient degradable soil nutrition amendment of the object of the invention, its characteristics are that it contains different components such as peat, humate, biomass water-holding agent, sapropel and big-and-middle trace element.
Component A: peat also claims the peat composed of rotten mosses.It is a kind of organic substance of pure natural, also is the good carrier of the natural bacterium of soil, contains various nutrient elements such as N, P, K and Ca, Mg, B simultaneously, has been acknowledged as the good modifying agent of aeolian sandy soil, desert soil.
B component: humate.It is sylvite, sodium salt or the ammonium salt that extracts from peat or weathered coal or brown coal etc. with basic metal or alkaline-earth metal.It belongs to water-soluble macromolecular organic compound, is the chief component of soil aggregate, has the functions such as transformation efficiency of stimulating plant growth, raising utilization rate of nitrogen fertilizer and phosphate fertilizer.It can also improve crop quality, improves the seed quality.
Component C: biomass water-holding agent.Be the biodegradable super absorbent resin of a kind of high-hydroscopicity that from corn, adopts one-step synthesis to generate of Northeast Normal University's development, have performances such as preserve moisture and fertility, drought resisting, and can the natural degradation (patent No.: 03127061.1).
Component D: sapropel.It is organic ooze of piling up under the backwater condition, contains certain organic matter, clay mineral and tiny shale, chiltern particle, has certain effect for conciliation Soil structure, increase soil organism tool.The used sapropel of the present invention be a kind of organic matter more than 3%, meet the fresh water sapropel of pollutent control criterion in the agricultural mud (GB 4284-84).
Component E: inorganic fertilizer.Comprise inorganic single fertile or its composite fertilizer of nitrogen phosphorus potassium, and at least a or several fertilizer of calcic, magnesium, sulphur, boron, chlorine, copper, iron, manganese, molybdenum, zinc element.
Component F: soda acid is adjusted agent.It can be sulfuric acid, hydrochloric acid, phosphoric acid or sodium hydroxide, potassium hydroxide, ammoniacal liquor etc.
The inorganic part that organic moiety of being made up of said components A, B, C, D and component E form constitutes the main component of soil fertility amendment, and component F is its ancillary component.
Each set of dispense ratio of soil fertility amendment should be considered concrete soil type or crop species, carries out suitable adjustment, particularly fertilizer type and the ratio among the component E.
Soil fertility amendment can be made powdered, directly applies on the modified soil; Also can carry out granulation behind the mixing, form the soil nutrient particle.
The powdered soil fertility amendment is one to realize goal of the invention according to the methods below.
Method one:
Component A, B, C, D, E are crushed to below the 1mm, by weight part, 60～95% component A, 1～3% B component, 0.1～3% component C, 0～45% component D, 1～5% component E, mix, use component F, its pH value is adjusted to about 6～8, and component A, B, C, D, E weight percentage sum are 100%.
Granular soil fertility amendment is realized goal of the invention according to method two.
Method two:
Component A, C, D, E are crushed to below the 1mm, mix, adjust the pH value 6～8 with component F according to component A, 0.1～3% component C, 0～45% component D, 1～5% component E by weight 60～95%.Deliver to granulating disc, the B component 1～3% of spraying liquid above the material bed that rolls, granulation 3～15min.Drying is 20～30 minutes under 80～150 ℃.Send the particle below the 2mm back to blender, again granulation.The specification of finished product is: circularity 2～3mm, intensity 15～30N, moisture 1～10%.
This soil fertility amendment, be with peat, humic acids, biomass water-holding agent, sapropel as main raw material, added that azophoska in the inorganic fertilizer and middle trace element make.It is a kind of integrate improve the soil, nutrition, stimulation and the organic-inorganic composite of economizing on water, degradable soil modifying agent.After using on aeolian sandy soil, the desert soil, greatly improve the structure of poor soil, make can well grow on it crop, vegetables or herbage; Use on the soil of degenerating, growing crop or vegetables can match in excellence or beauty with the like product on the rich soil; Use on the soil preferably in fertility, can replace chemical fertilizer 1/4～1/3, water saving 1/3～1/2 can reduce the use of agricultural chemicals simultaneously.
