Abstract
The invention provides a water-holding fertilizer manufacturing method and a water-holding fertilizer product. In the method, a water-holding fertilizer is prepared by mixing water-holding materials for producing the water-holding fertilizer in a preprocessor and by mixing fertilizer particles in a coating machine and coating water-holding material films on the fertilizer particles. The invention belongs to a novel manufacturing process and novel product of water-holding fertilizer.
Description
Technical field
The present invention relates to agricultural water storage material and fertilizer, particularly relate to a kind of manufacture method and product of novel water storage fertilizer.
Background technology
In agriculture production, be extensive use of various fertilizer, mainly be chemical fertilizer of simple substance for example urea, sulphur ammonium, Repone K, coarse whiting etc. and contain, the polyelement composite fertilizer of nitrogen, phosphorus, potassium and other nutritive element, these fertilizer all are the granulated fertilizers of making by certain technology and equipment.They can provide various nutrients to the growth of plant.Also made contribution for the increasing both production and income of peasant household.But the growth of plant also be unable to do without sunlight, these conditions of moisture except needs fertilizer nutrient, and especially in the arid area of little precipitation, the underproduction or total crop failure have been not news concerning us significantly because of lack of water causes farm crop.If we can provide the function of water storage water conservation again when providing fertilizer nutrient for farm crop, so a kind of fertilizer can provide bigger help for the increasing both production and income of peasant household.
The water storage material made from absorbent resin, various precipitation of retaining and rapid absorption or even neutral dew in a large number.Because the water of attracting deposit therein is difficult for by rapid evaporation, so can make soil in the long relatively time, keep certain wettability, therefore be particularly suitable for arid area short of rain, also can reach water-saving purpose to the area of lack of water not, its contour structures also has positive effect to the soil moisture conservation of soil simultaneously.The floss material also helps the procreation of microorganism in the ventilation property of soil and the soil very much, has the effect of significantly keeping soil from packing together and improveing soil property.But the water storage material that absorbent resin is made mostly is floss and powder body thing shape, and simultaneously proportion is also very light, and will to expend a large amount of manpower be very uneconomic and the poor effect method as directly use the water storage material in the land for growing field crops.
Make water storage fertilizer with existing fertiliser granulates and absorbent resin material, because the water storage material itself is that cotton-shaped elastomerics can't make itself and fertiliser granulates be combined into new product granulating.Therefore relevant water storage fertilizer does not appear in the newspapers.
Summary of the invention
The present invention is intended to overcome the defective that exists in the above-mentioned technology, a kind of manufacture method of water storage fertilizer is provided, it is to contain a kind of new-type fertilizer product that the needed nutritive element of farm crop has water storage drought resisting function again simultaneously, the production technique of this kind new-type fertilizer is simple, and reduces the energy consumption of production process and realize the production process three-waste free discharge.
This new-type fertilizer has very large difference with fertilizer is arranged now in appearance, and its profile is different fully with former manufacture method, and product particle is to be designed to a kind of lint spheroidal particle or smooth, spherical particle as required.
The invention has the advantages that:
A, this product have outside the fertilizer advantage, also have water storage drought resisting function;
B, product particle shape can be that the spherical or smooth spherical particle of lint has the market differentiation;
C, product particle do not lump, and have the higher market competitiveness;
D, good operational environment, three-waste free discharge belongs to process for cleanly preparing;
E, the simple less investment of processing unit.
The principle of the invention is, particulate material ratio is on demand mixed in coating machine, behind particle surface coating adhesives, the water storage material sprayed the particle surface that adds in the coating machine carry out coating, obtains water storage fertilizer.
Technical scheme of the present invention is as follows:
