Description

TECHNICAL FIELD [0001] The present invention relates to an effervescent silicate fertilizer composition for use in a water-

The present invention relates to a composition of a foamable silicate fertilizer for flood-prone fresh water crop cultivation using a water-leveling agent used for growing rice, and more particularly, to a composition of a silage fertilizer The silicate fertilizer is fertilized in a floated state floating on the water surface. When the silicate fertilizer is fertilized as described above, the spread of the silicate fertilizer is accelerated due to the floating property of the water, so that it is possible to produce a tablet which can uniformly apply the silicate fertilizer to the entire rice field.

Silicic acid fertilizer is an essential inorganic nutrient that absorbs large amounts of manure and crops such as rice, barley, and wheat. It increases potassium and lignin in the crop body to strengthen the stem to reduce the clothes, reduce total nitrogen and magnesium content, Reduces the incidence of disease and improves photosynthetic efficiency and building production efficiency and raises the maturity rate by maintaining the upright position of the leaves. In addition, the silicate component is known to increase the amylose content of rice, but it improves the quality by lowering the protein content. It improves the physicochemical characteristics of paddy soil, corrects the pH of paddy soil, increases the desorption rate of adsorbed phosphoric acid, Of phosphorus, and it has been known that it has the function of reducing the toxicity of iron and manganese by increasing the oxidizing power of roots.

Rice requires a very large amount of silicate compared to other crops, and the silicate content in the rice straw is 12 ~ 14 wt% in large quantity. The silicate ingredient is a component that can be absorbed only in the soil. In case of rice, Lt; RTI ID = 0.0 > a < / RTI > Although silicic acid is an indispensable element for the growth of rice, silicate content in domestic paddy soil is insufficient for use during the growth period of rice.

The soluble silicate content of paddy soils in Korea is usually 70 ~ 80ppm, which is low compared to 157ppm. Despite the fact that the rice silage absorbed in rice has to be reduced to the soil even only the rice straw, the rice straw is also supplied to the livestock farming farm in the form of silage, and the silicate content in the soil is gradually becoming insufficient and application of silicate fertilizer is continuously required have.

Therefore, in order to improve the growth of rice, silicate fertilizer should be fertilized so that silicate fertilizer can be continuously supplied to the rice growing season.

Korean Patent Registration No. 10-1064899

The present invention is directed to the production of foamable silicate fertilizers for water-borne flood-control crops with water-borne floating properties so that rice can be continuously absorbed by silage fertilizer over a period of time. In the rice cultivation, the foliar application of silicate fertilizer is generally the most hot summer season. Therefore, in order to fertilize the silicate fertilizer, the use of rice silage fertilizer is limited due to the difficulty in handling rice paddies with heavy sprayers or hoses.

Conventionally, in order to solve the problems of the existing silicate fertilizer, a foaming throwing type silicate fertilizer which is thrown from the river has been used. However, in this method, the silicate fertilizer tablets thrown in are put on the bottom of the rice paddy so that the foaming is not completed, There is a problem that it does not spread smoothly.

The present invention relates to a foamable silicate fertilizer for flood-prone fresh water crop cultivation in which a water surface floating function is added so that even when the foamed thrown type silicate fertilizer is thrown on a rice paddy, Thus, when the foamy silicate fertilizer floats on the surface of the water, the silicate component is uniformly discharged while flooding the surface of the rice so that the silicic acid component is continuously supplied during the growth period of the rice.

For this purpose, the present invention uses a water-borne flocculant in the foamable silicate fertilizer composition, and the water-borne float agent used in the present invention is borosilicate. When 4.5% by weight of borosilicate was mixed with the expandable silicate fertilizer composition, the silicate fertilizer tablets floated well in the paddy, but when the mixture was mixed at 3% by weight or less, the tablets did not float. Therefore, it was judged that the optimum content of borosilicate required for the production of the foamable water surface silicate fertilizer was 4.5 wt% or more.

The composition of the foamable tablet type silicate fertilizer using the water surface-suspending agent of the present invention comprises 5 to 50 wt% of silicate, 30 to 70 wt% of foamable agent, 10 to 15 wt% of binder, 5.5 to 15.5 wt% of excipient, 15% by weight.

In the present invention, 5 to 50% by weight of a silicate, 30 to 70% by weight of a foamable agent, 10 to 15% by weight of a binder, 5.5 to 15.5% by weight of an excipient and 4.5 to 15% by weight of a water- Make a composition of water-borne silicate fertilizer for flood-prone freshwater crop cultivation.

When rice is cultivated in paddy fields, fizzy silicate fertilizer is thrown from the paddy field and fertilized. However, when the flocculent silicate fertilizer for flooding the water-floodable fresh water crop of the present invention is thrown, the silicate fertilizer floats on the water due to its floating nature, and the silicate fertilizer component is uniformly supplied to the rice field to dramatically increase the spreadability of the fertilizer .

In addition, the silicate fertilizer is uniformly supplied throughout the entire growing period of the rice, so that the rice grows healthy.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, preferred embodiments of the water-swellable foam-diffusing silicate fertilizer of the present invention will be described in detail with reference to the accompanying drawings. It is to be understood that the present invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, It is provided to inform.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a diagram of a silicate fertilizer thrown point for testing the diffusibility of silicate fertilizer in the interior of the present invention.

The present invention relates to a method for producing a foamable silicate fertilizer for flood-prone fresh water crop cultivation, wherein a foamable silicate fertilizer is floated on the surface of a rice paddy while being thrown from a paddy field using a water leveling agent so that diffusion can be smoothly performed.

When rice is cultivated in the rice field, foliar silicate fertilizer is thrown in the rice paddies in the fresh water state. The surface of the soil is very viscous, so if the silicate fertilizer weighs a lot, It gets stuck on the floor. Thus, when the silicate fertilizer tablet is stuck to the bottom of the rice paddy, the foaming does not proceed to the end, so that the concentration of the silicate fertilizer differs in the rice paddy and the spread of the fertilizer ingredient is not constant.

In order to solve such a problem, the present invention is to increase the diffusion property so that the silicate fertilizer component can be uniformly supplied to the rice field by floating the foamable silicate fertilizer having the property of sinking below the water surface on the rice.

The inventive foaming silicate fertilizer for the water-swellable freshwater crop cultivation of the present invention was invented by mixing the silky fertilizer manufactured by the method of manufacturing foamable silicate fertilizer of the present invention (Korean Patent No. 10-1064899) A water leveling agent such as soda lime borosilicate glass was used as the water leveling agent used in the invention.

When the borosilicate is mixed with the expandable silicate fertilizer, the specific gravity is lowered and floated in water. Such borosilicate may exist in various forms such as rods, spheres, and plates. The borosilicate used in the present invention is a white powder of light hydrophobic microcrystals having an aspect ratio of 0.05 to 0.3, preferably 0.1, which facilitates the floatation of the tablet upon mixing with the expandable silicate fertilizer. When the amount of the borosilicate mixed with the expandable silicate fertilizer is less than 3% by weight, it can not float on the surface of the artificial lake. If the amount of the borosilicate is 15% by weight or more, the proportion of other ingredients decreases and molding becomes difficult. The optimum borosilicate content used in the present invention is 4.5 wt% to 10 wt%.

In order to make the foaming silicate fertilizer have the property of surface flotation, a conventional surfacing agent such as borosilicate is added to the foamable silicate fertilizer composition. In this case, selection of the raw material and optimization of the content and ratio are necessary.

In the present invention, 5 to 50% by weight of a silicate, 30 to 70% by weight of a foamable agent, 10 to 15% by weight of a binder, 5.5 to 15.5% by weight of an excipient and 4.5 to 15% by weight of a water- Make a composition of water-borne silicate fertilizer for flood-prone freshwater crop cultivation.

The silicate used in the preparation of the foamable silicate fertilizer for water-borne floating freshwater crop production is selected from at least one of potassium silicate and sodium silicate, and the foamable preparation is prepared by mixing carbonate and organic acid at a ratio of 1 to 2.5: 1 do.

The carbonate is prepared by selecting at least one of sodium carbonate, sodium bicarbonate, potassium carbonate, potassium bicarbonate, calcium carbonate, ammonium carbonate, ammonium bicarbonate, and magnesium carbonate, and the organic acid is selected from citric acid, malic acid, tartaric acid, maleic acid, phthalic acid, adipic acid , And succinic acid.

Polyethylene glycol (PEG6000) was used as the binding agent.

As the excipient, a sustained release base material and a diluent were used to suppress the direct reaction between the silicate and the organic acid.

At least one component selected from cellulose acetate phthalate (CAP), polyvinyl acetate phthalate (PVAP) and hydroxypropylmethyl cellulose phthalate (HPMCP) may be selected as the sustained release substrate, and at least one of lactose and talc may be selected as a diluent .
