Description

TECHNICAL FIELD The present invention relates to a slow-acting fertilizer to be applied to plants to be planted on the slopes of roads, etc., and is particularly manufactured by applying a waterproof coating to the fertilizer components. Therefore, it relates to a fertilizer capable of maintaining fertility over a long period of time.

(Prior art) Conventionally, a road constructed by cutting other mountains is sloped,
Or, in order to prevent the soil on the slope from flowing down on the sloped part of the residential land development site, or from an aesthetic point of view, affix a lawn or sow seeds such as grass and perform greening work. Is generally done. In the sloped part formed by cutting other mountains or filling up as mentioned above, the fertilizer retention is not good even when lawn is pasted, especially when there is a lot of rain such as the rainy season. As the fertilizer sprayed dissolves in water and flows out more frequently, it is necessary to frequently supplement the fertilizer.

This is because, in particular, microorganisms that decompose fertilizer components act vigorously in a water-rich state to let out effective fertilizer components to grass and the like. Therefore, in the conventional slope greening work, various methods such as using a method in which the fertilizer component is stored in a bag impregnated with asphalt and the fertilizer component etc. gradually goes out of the bag for a long period of time, are used. The method of was devised, and it is effective as it is.

(Problems to be Solved by the Invention) However, the conventional method for supplying fertilizer to slopes as described above requires a relatively large amount of time and labor, and in particular, the fertilizer components and the like are stored in a bag. Construction work such as sticking to the slope in this state is very inefficient. Further, as described above, setting the fertilizer application period to be short and increasing the number of fertilizer applications has a large effect, but it requires a great deal of manpower and further If it rains immediately after that, the fertilizer will flow out, and there are many drawbacks such as the maintenance cost for slope greening is very high.

On the other hand, instead of using the fertilizer component alone,
Encapsulating the fertilizer component in a microcapsule or the like, or coating a waterproofing agent around the fertilizer component can be considered, but when such a means is used, the production cost of the fertilizer increases significantly, It is difficult to develop a technique for freely controlling the delayed effect. In other words, organic fertilizers and inorganic fertilizers have many problems such as different materials of capsules, effects of microorganisms and bacteria in the soil, effects of sunlight etc. in different regions. There may be problems such as not being able to use the same fertilizer in different areas.

(Object of the Invention) The present invention eliminates the drawbacks of the slope greening work that has been conventionally used as described above. The fertilizer component is impregnated with a waterproofing agent and a fungicide, and the fertilizer component is added. It is an object of the present invention to provide a fertilizer which can be sprayed in a state coated with a chemical having a waterproof property and the fertilizer component is eluted over time.

(Means and Actions for Solving Problems) The slow-acting fertilizer of the present invention comprises a waterproof component such as a metal soap component or silicon, a fungicide component such as paraffin or an acrylic resin, and a petroleum solvent such as xylene. It is manufactured by dispersing it into a fertilizer component, dispersing and mixing the drug into a fertilizer component, and then permeating the drug into the fertilizer component. Further, in the present invention, an organic fertilizer as a fertilizer component or a compound fertilizer can be used as a target, and the fertilizer component is sprayed with a drug having permeability and waterproofness, and is produced by stirring. be able to. Furthermore, in the present invention,
It is also possible to adjust the effective period of the fertilizer by changing the mixing ratio of the components contained in the drug.

Therefore, when the slow-acting fertilizer of the present invention is used for slope greening, the active ingredient as a fertilizer is gradually eluted over a long period of time, and water or moisture is supplied and microorganisms or bacteria in the soil are supplied. As a result, the drug coating the fertilizer component is decomposed and effectively acts on the lawn on the slope, and the effect of the fertilizer component continues for a long time.

(Example) The slow-release fertilizer of the present invention is a fertilizer produced by mixing inorganic fertilizer components such as chemical fertilizers, organic fertilizers such as compost fermented very well, or by mixing them. It is possible to use the manufactured fertilizer and the like. When the above-mentioned fertilizer components are sprayed on lawns or the like, they are decomposed by the water supplied by rain or the like and the activities of microorganisms, bacteria and the like in the soil to produce effective components for plants. The presence of water is indispensable for the production of such fertilizer components, and under dry conditions, microorganisms, bacteria, etc. cannot act, so the fertilizer components remain as they are. .

Therefore, even if you spray fertilizer as a lawn curing agent on an inclined slope, if the environment is a dry area, the fertilizer will not immediately have any effect, but when it rains, microorganisms etc. will start their activities. Therefore, the effect of spraying fertilizer is exerted after it rains.

However, when fertilizer is sprayed on the slope, as mentioned above, the fertilizer component rarely penetrates into the soil after rain, and the decomposed active ingredient flows on the slope surface. It is easy to cause an inconvenient situation that the grass is not effectively absorbed. This is particularly prominent in chemical fertilizers and the like that have immediate effects, and waste is easily generated in the applied fertilizer.

In order to solve such an inconvenient state, the present applicant has conducted extensive studies, and as a result, by mixing a water-proof component and a drug containing a component capable of coating and holding the fertilizer component with the fertilizer component, It was found that a slow-acting fertilizer can be obtained. In the slow-acting fertilizer of the present invention, a component exhibiting waterproofness, and a component for coating the fertilizer component, metal soap, a waterproof / water-repellent component such as silicon, paraffin, a surface protective action of acrylic resin, etc. A chemical prepared by dispersing the antifungal component in xylene or an aliphatic solvent and mixing a solvent such as isopropyl alcohol or an aliphatic solvent is used. And
The slow-acting fertilizer of the present invention is manufactured by mixing the above-mentioned chemicals with the fertilizer component and coating the fertilizer component with a nonuniform size. The chemicals containing the waterproof / mildew-proofing ingredients as described above,
It can also be applied to the surface of bamboo, grass, wood to protect them and keep them aesthetically pleasing, and other materials that have the property of coating such surfaces. It is also possible to use drugs.

In addition, the above-mentioned chemicals generally have a waterproof property and also contain a component that forms a film on the surface of the applied object. Then, by applying a drug having such properties to the surface of wood or the like, the component contained in the drug penetrates into the wood, and after evaporation of the solvent component in the drug, the surface of the object to be treated and It forms a film by a chemical reaction along the capillaries, and has the effect of blocking the activity of microorganisms and bacteria.

In the delayed-release fertilizer of the present invention, a drug containing another coating component similar to the above-mentioned contained components, or a drug having a waterproof property having an effect equivalent to that of the drug can be used. Then, when the fertilizer is produced, the chemicals having the above-mentioned components are mixed in the fertilizer and stirred to form a coating on the surface of the mass while the chemicals penetrate into the mass of the fertilizer component. , Even when sprayed on the soil,
Allows long-term fertility. In addition, the fertilizer produced as described above forms a film on the surface of the lump, so that moisture does not rapidly penetrate into the large and small lumps, and mold and other microorganisms grow in the fertilizer. The antifungal property can be exhibited without any need, and the active ingredient of the fertilizer can be retained as it is.

For example, when considering the waterproofness of fertilizer, if the rate of the fertilizer components not dissolving in water when the water is added after the waterproofing treatment is taken as the waterproof rate, the waterproof rate is actually 70- 90%
It has been found that setting to 0 gives good results.

Therefore, in the slow-acting fertilizer of the present invention, when a chemical fertilizer is used, when the components of the three elements of nitrogen, phosphoric acid, and potassium fertilizer are mixed, the fertilizer components are sufficiently stirred and mixed, and then the fertilizer is used. And 0.03% of the drug is sprayed and thoroughly stirred to allow the drug to be impregnated into the fertilizer component. As a result, the fertilizer has a waterproof property of about 90%, and the fertilizer component is impregnated with the waterproof component and the like by the mixing and stirring in the manufacturing process, and the fertilizer component covers the surface thereof. Furthermore, when using the above-mentioned agents, it is possible to change the waterproof property by changing the mixing ratio with the fertilizer, and thereby the fertilization period can be arbitrarily controlled. .

Therefore, in the slow-acting fertilizer produced as described above, the fertilizer component is not immediately decomposed, and a part of it is immediately decomposed by the activity of microorganisms in the soil, but other main components. The part remains, and over a long period of time, the fertilizer component flows out as the drug component naturally loses its effectiveness, and it is decomposed by microorganisms or bacteria in the presence of water, and And will work effectively.

Incidentally, the drug mixed in the fertilizer of the present invention is not limited to the specific drug as described above, in addition, the solvent, as long as it is harmless to plants, other components It is also possible to use drugs that have. Furthermore, the agent that exerts the waterproof property or the property of covering the surface that is dissolved in the solvent is not limited to the specific product as described above, and has an equivalent property that is generally commercially available in the past. It is also possible to use drug components.

(Effect of the invention) Since the slow-acting fertilizer of the present invention is produced as described above, it becomes possible to easily adjust the fertilizing period, and thus the target plant and slope It is possible to provide a fertilizer that works effectively according to the condition and the like.

Further, the slow-acting fertilizer containing the waterproof component of the present invention, the waterproof component loses the effect of waterproofing and surface coating under the natural environment, so that the fertilizer component is gradually supplied to the plant over a long period of time. be able to. Further, in the present invention, since the state of forming a film on the surface of the fertilizer using the waterproof component, it is possible to suppress the growth of mold and unnecessary microorganisms, the fertilizer gradually as the water is supplied. Since the components are dissolved in water and decomposed by microorganisms, bacteria, etc., they are not washed away immediately by rain or the like, and their efficacy can be maintained for a long time. Therefore,
By using the slow-acting fertilizer of the present invention, the number of times the fertilizer is applied to the slope can be reduced, and the maintenance cost for greening slopes and the like can be reduced.
