Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a horticultural fertilizer having a beautiful appearance and excellent quality.

Today, chemical fertilizers formed into granules are available on the market, and because they are easy to apply and odorless, they are particularly suitable for indoor gardening and balcony gardening.

However, while liquid fertilizers (concentrated liquid fertilizers) and water-soluble fertilizers (powder dissolved in water) seep into the soil and disappear visually after application, the above-mentioned molded fertilizers themselves Because it has a shape that gives the impression of a foreign body that does not blend in with the soil, it is an eyesore when fertilized, and there is a risk that it will spoil the beauty of flowers and plants.

This drawback is particularly noticeable in bonsai, potted plants, planters, etc. indoors or on balconies that are often touched on a daily basis.

The inventors of the present invention have conducted various studies to provide a gardening fertilizer that does not have the above-mentioned drawbacks, and have found that when a chemical fertilizer mixture containing dissolved phosphorous fertilizer is molded into crushed stone, a product similar to decorative sand made from crushed marble is produced. is obtained, and it has a beautiful appearance when fertilized.
It was discovered that there is no risk of damaging the beauty of flowers.

The present invention was completed based on this knowledge, and consists of compressing a chemical fertilizer mixture containing dissolved phosphorus fertilizer and at least one other poorly soluble fertilizer into flakes with a thickness of 4 to 6111711, and then crushing the mixture. 8 have a sieve size of 1.8 to 4.8 mm.
This is a gardening fertilizer that has a cosmetic sand-like appearance and is made by sizing the particles to have a coefficient of 0 or more.

As mentioned above, the present invention contains dissolved phosphorous fertilizer as an essential component, and the amount thereof is preferably about 5 to 30%.

In contrast to other chemical fertilizer ingredients, which are almost white, dissolved phosphorous fertilizer has a dark green color derived from its raw material, such as serpentine, so by incorporating it, the product fertilizer becomes white. Dark green particles such as serpentinite contained in melted phosphorus fertilizer are scattered among the crushed stone pieces, giving it an interesting appearance as if it were crushed natural marble.

Dissolved phosphorous fertilizer is sparingly soluble, but the present invention requires at least one other sparingly soluble fertilizer.

As a result, the fertilizer of the present invention is slow to disintegrate during irrigation and can maintain the above-mentioned crushed stone appearance for a considerable period of time even after application.

Examples of this poorly soluble fertilizer include formaldehyde-processed urea fertilizer, IB (isobutyraldehyde-processed urea fertilizer), and CDU (acetaldehyde-processed urea fertilizer).
Nitrogen fertilizers such as are suitable, and potassium fertilizers such as potassium silicate can also be used.

Horticultural fertilizers often tend to be over-applied;
Concentration problems may actually inhibit plant growth, but such dangers can be avoided by using poorly soluble fertilizers.

In addition to the above-mentioned poorly soluble fertilizers, easily soluble fertilizers may be blended in the present invention as required, examples of which include ammonium sulfate, ammonium phosphorus, lime superphosphate, potassium sulfate, potassium chloride, and the like.

In order to maintain the fertilizing effect evenly from the early stage of plant growth to the late stage of plant growth, it is rather practical to use both the slightly soluble fertilizer and the easily soluble fertilizer described above in combination.

Forming the fertilizer mixture into flakes and then pulverizing can be carried out using, for example, a conventional roller compactor, flake breaker, etc.

By defining the thickness of the flakes and the grinding particle size as described above, a crushed stone appearance is obtained.

The present invention is carried out as described above, and according to this, a fertilizer with an appearance that closely resembles a decorative frame made of crushed marble can be obtained, so it does not look strange to plants and can be used for bonsai, potted plants, etc.
Not only is there no risk of spoiling the aesthetic appearance of planters, etc., but it has the effect of enhancing the appearance of these items.

Examples are shown below.

Example 1 Form nitrogen 13.2%, ammonium sulfate 19.2%, ammonium phosphorus 6.5%
%, dissolved phosphorous fertilizer: 15.0%, peroxide phosphoric acid lime: 25.3%, and potassium sulfate: 20.8%, and the mixture was mixed well with a roller compressor at a roller pressure of 3 to 4 t/cIIL.

It was molded into flakes with a thickness of 4 to 6 mm under a roller rotation speed of isrpm.

Next, the flakes were crushed using a flake breaker and sized using a sieve of 1.8 to 4.8 mm.

The particle size distribution of this material is 4.80 to 4.00 mm:
18.5%, 4.00-2.83mm: 35.4%
, 2.83-2.00712m: 31.9%, 2.
00 to 1.80%: 10.9%, and it was a beautiful product with an appearance similar to decorative sand made from crushed marble.

When this material was applied to the topsoil of a No. 5 pot containing Akadama soil and watered every day, the crushed stone state was maintained without crumbling for three months.

Further, when a fertilization test of this product was carried out using pansies planted in a No. 4 pot, it was found that the appropriate amount is 2 to 4 g, and no concentration disorder occurs unless the amount is 5 times or more.
