Technical field

The invention belongs to the Technology field of fertilizer, be specifically related to a kind of peanut cultivation water-retaining fertilizer and preparation method thereof.

Background technology

In view of the present situation of current China chemical fertilizers production application, since the eighties in 20th century, the a large amount of uses on Vegetable produce of chemical fertilizer, agricultural chemicals, cause soil compaction, degree of salinity is aggravated, to the serious threat that agroecological environment is formed, cause underground water to drink pollution simultaneously, landed property area is little per capita in China, how to utilize limited land resources, under the prerequisite ensureing soil sustainable utilization, the vegetables product of production high-quality, safety, becomes the important topic of various countries agricultural science and technology worker research.Based on above reason, people propose to use fertilizer additive, and to improve, utilization rate of fertilizer is low, the feature of the wasting of resources and Water Eutrophication.

Summary of the invention

A kind of peanut cultivation water-retaining fertilizer, it is characterized in that, be made up of the raw material of following weight part: the hydrochloric acid soln 40 ~ 60 of straw powder 10 ~ 15, the porous peat composed of rotten mosses 5 ~ 8, bagasse 15 ~ 20,0.1mol/L, quartzite 10 ~ 15, urea 15 ~ 20, trace element 2 ~ 5, potassium sulfate 20 ~ 30, primary ammonium phosphate 25 ~ 35, potassium humate 8 ~ 14, fertilizer additive 5 ~ 8 and appropriate water;

Described fertilizer additive is made up of following raw material: terra alba 10 ~ 15, oleum lini 4 ~ 6, vinylbenzene 10 ~ 12, sodium stearate 1 ~ 2, N hydroxymethyl acrylamide 2 ~ 3, ethanol 8 ~ 10 are appropriate water; Preparation method is: by ethanol and water with 1: 10 ratio dissolve each other after put into reactor, add vinylbenzene and N hydroxymethyl acrylamide, be heated to 70 ~ 80 DEG C, stirring and dissolving, mixing oleum lini and sodium stearate join in the water of 4 ~ 5 times of its total weight parts, bubble after stirring 10min, then join in aforesaid reactor, heating and thermal insulation, and stirring 0.5 ~ 2h carries out composite under the rotating speed of 300 ~ 500r/min, finally terra alba was finely ground to 200 mesh sieves to add in total material to stir and make emulsion, and was incubated for subsequent use and get final product.

A preparation method for peanut cultivation water-retaining fertilizer, is characterized in that, comprises following step:

(1) pulverized by quartzite, grinding and sieving net, must be the particle of 40 ~ 60 mesh sieves, the hydrochloric acid soln putting into 0.1mol/L stirs 10 ~ 15min, soaks quartzite particle washing 2 ~ 3 times after filtering out hydrochloric acid with clear water;

(2) be ground into powder by after bagasse drying treatment, then mixed straw powder and the porous peat composed of rotten mosses, add the water of its weight part 1/2 times, stir into uniform pasty state;

(3) mixing urea, trace element, potassium sulfate, primary ammonium phosphate, potassium humate and other following remaining component do not related to, add the paste-like material described in (2), stir;

(4) preheating fertilizer additive to 80 ~ 100 DEG C in coating machine, be sprayed at the quartzite particle surface described in (1) of rolling with the form of spraying, be added in (3) described total material after cooling under normal temperature, machinery rolling stirring 20 ~ 30min, adjustment water content to 22%, granulation.

The present invention is according to the root problem in fertilizer current generation, and namely utilization rate of fertilizer is low, and fertilizer efficiency is slow, nutrient supply is unstable and easily cause the shortcoming of body eutrophication, prepares a kind of concentrated fertilizer with fertilizer additive, completes by the following method:

Described fertilizer additive is a kind of with styrene resin alicyclic monomer, binding agent N hydroxymethyl acrylamide is coordinated to be a kind of high performance water-soluble material prepared by main body, wherein add the sliminess that plant oil oleum lini increases main body, add sodium stearate as surfactant, then oleum lini and the perfection of resene monomer agree with, form a kind of additive with high bonding characteristic, present gluing form, finally add terra alba, refining grinding, determine the granularity of terra alba, add as a kind of structural agent, make main body more stable.

This additive generally coordinates bigbore talc particles together to use, the rock particles with improvement soil characteristic is ground into the particulate state of certain particle size size, then acid or base extraction is used, make smooth powder particles surface irregularity, then fertilizer additive to 70 ~ 80 DEG C are heated, join the surface of aforementioned powder particles, stirring and evenly mixing becomes thickener, naturally cooling is also air-dry, again be crushed to fine particle agent after air-dry, coordinate Inorganic chemical composition and organic fermentation material composition etc. to make powder;

The object of such preparation is the bonding characteristic and the adsorption that utilize additive, effectively prevent the loss of fertilizer nutrient, combine with talc particles, in the process of fertilising, if need water fertilising, the fertilizer dissolved can discharge talc particles, talc particles precipitation enters soil, be attached near root system of plant, the scope internal adsorption ability of zonule is strengthened, and the factor of the useful plants growths such as attached microbial, mineral ion and organic acid is adsorbed, and can reach effective utilization rate of fertilizer, promote the absorption of fertilizer, and permanently effective.

Advantage of the present invention: the present invention is a kind of peanut cultivation fertilizer of water-maintaining, main raw material is by the quartzite powder of the peat composed of rotten mosses, stalk powder, bagasse and pulverizing, be conducive to sandyization soil layer construction, organic matter is form colloid form after main fiber system powder adds water simultaneously, there is the effect of bonding soil, prevent moisture penetration and moisture evaporation simultaneously, play the effect of moisturizing.
