Technical field

The invention belongs to the Technology field of fertilizer, be specifically related to trace element fertilizer of a kind of rice terrace efficiency utilization 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 trace element fertilizer of rice terrace efficiency utilization, it is characterized in that, be made up of the raw material of following weight part: the hydrochloric acid soln 30 ~ 45 of Muscovitum 10 ~ 15,0.1mol/L, attapulgite 10 ~ 12, plant ash 4 ~ 6, urea 25 ~ 30, zinc chloride 1 ~ 3, potassium humate 5 ~ 8, trace element 8 ~ 10, diammonium phosphate 15 ~ 20, fertilizer additive 4 ~ 5 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 the trace element fertilizer of rice terrace efficiency utilization, is characterized in that, comprises following step:

(1) pulverized by Muscovitum, grinding and sieving net, must be the particle of 40 ~ 60 mesh sieves, the hydrochloric acid soln putting into 0.1mol/L stirs 5 ~ 10min, washs 2 ~ 3 times after filtering out hydrochloric acid with clear water;

(2) mixing urea, zinc chloride, potassium humate, trace element and bicarbonate of ammonia, be ground into pulvis with pulverizer, appropriate water spray wetted surface but do not dissolve;

(3) preheating fertilizer additive to 100 ~ 110 DEG C in coating machine, are then sprayed at the particle surface described in (1) of rolling, mix under normal temperature after cooling with the pulvis described in (2) with the form of spraying, machinery rolling stirring 10 ~ 15min;

(4) be added to after attapulgite and plant ash being mixed in the total material described in (3), stirring and evenly mixing, adds water to water content 20%, granulation in right amount.

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.

Beneficial effect of the present invention: the present invention is a kind of rice terrace plantation trace element fertilizer of efficiency utilization; fertilizer is mixed into by the talc particles of fertilizer additive coating; there is absorption, stick and the reserved function storing fertilizer; after being administered to rice terrace; be immersed near rice root; reduce loss and the body eutrophication of flow action, the paddy rice of plantation is a kind of paddy rice of rich trace elements.
