Description

DETAILED DESCRIPTION OF THE INVENTION 1-1 The present invention relates to a method of applying slow-release fertilizer, particularly a method of applying it to a slope, and materials used therein.

Recently, as more and more civil engineering works such as roads, railways, and land reclamation have been carried out in mountainous areas, large-scale slope construction has become more common.
Planting vegetation on slopes became popular due to aesthetic and slope protection requirements.

Although it varies depending on the region, geology, weather, and other conditions, it takes at least three years, sometimes five years, for native plant species to take root on the slope.

A necessary condition for vegetation construction is to protect the slope until the native species become established.

In general, there is less nutrients on slopes, and given the local conditions, it is best to add fertilizer later.

Recently, slow-release fertilizers that are effective over a long period of 2 to 3 years have been developed, and there are also appropriate application methods.

The most excellent material and method at present is published in the published patent publication No. 56.
It is a slow-release fertilizer mainly consisting of isobutylidene diurea solidified into large particles as in No. 61716, and is applied to the slope as uniformly as possible. The effectiveness of this fertilizer has been proven for 2 to 3 years.

The present invention aims to provide a method that uses a similar slow-release fertilizer and exhibits a longer-term fertilizer effect.

Embodiments of the invention will be described in detail with reference to the drawings.

FIG. 1 shows a case in which slow-release fertilizer (1) solidified into large particles is individually enclosed using a water-permeable plastic net (21) and connected in a straight line.

Figure 2 shows similar slow-release fertilizers individually sealed with a thin, water-impermeable polyethylene film (3) and connected in a straight line.

In addition, slow-release fertilizer solidified into large grains is particularly defined as a fertilizer containing imbutylene diurea manufactured by Mitsubishi Chemical Industries, Ltd. as its main component, and usually containing 5 or 5 or It is shaped like a dowel or a disc.

As the packaging material used in Fig. 2, plastic films such as polyethylene, polypropylene, and soft PVC are suitable, and the thickness thereof is generally 0.01~001wn.
Preferably, it is in the order of 0.02 to 0.05. It is preferable that these films do not contain antioxidant II agents or ultraviolet absorbers to prevent embrittlement.

In the construction of the present invention, as shown in Figure 3, one wire sealed with a plastic net and one wire sealed with a plastic film are combined, and one to two wires are placed on the slope.
Place them in a striped pattern at m intervals and fix them using skewers (4), etc.

Plastic film is durable and water-resistant, so the slow-release fertilizer sealed inside won't be washed away by rainwater or come into direct contact with the roots of plants, making it ineffective. However, polyethylene and polypropylene films are degraded by ultraviolet rays, and soft PVC films lose their plasticizer and become brittle, so even if they are covered to some extent by soil and plants, they are left outdoors and exposed to the wind and rain, resulting in high temperatures. As it undergoes repeated changes every day, it becomes brittle and eventually becomes punctured or torn by plant roots, stems, and soil. 0.02~0.
When a film with a thickness of 05111111 is used, the slow-release fertilizer that has been sealed is exposed for one to several years, depending on the conditions under which it is left, and exhibits its fertilizing effect.

Since the present invention is configured as described above.

Immediately after fertilization, rainwater and anything that comes into direct contact with the roots exerts its fertilizing effect for two to three years, and during that time, the slow-release fertilizer sealed in a plastic film gradually comes into direct contact with the outside and exerts its fertilizing effect. ζ Recommended.

Since the fertilizer starts to work later, it can continue to be effective until later in the day, and it is very convenient because it allows plants to flourish between the soil until native species take root, reducing the cost of adding fertilizer. The significance of the present invention is significant when considering the risks such as slope collapse in the case of dynamic movement.

In this example, we used a plastic film that was sealed in a plastic film 5 and connected in a straight line because it was easy to apply uniformly and labor-savingly on the slope, and because it was more efficient to wrap it continuously using an automatic packaging machine. I used it.

The gist of the present invention is to apply a fertilizer that exhibits fertilizing effect immediately after fertilization, and at the same time apply a fertilizer whose effect is delayed for one to several years, so it is not necessarily necessary to use linked fertilizers. As shown in Figure 4, slow-release fertilizer (1) solidified into large particles may be sealed one by one in a plastic film, or polyolefin in a molten or suspended state, acrylic in vinegar, etc. The effect of fertilizer may be delayed by coating the surface with a thin layer of plastic.

As shown in Figure 5, one original slow-release fertilizer and one fertilizer sealed in a plastic film were alternately sealed in a water-permeable plastic net (2) and connected in a straight line. The storage area is convenient for application to slope surfaces.

Claims (3)

[Claims] (1) Solidified into large particles, some of which are directly exposed to rainwater, and some of which are sealed with water-resistant materials such as polyethylene film, but which become brittle if left outdoors for long periods of time. This method of fertilization is characterized by applying slow-release fertilizer at the same time. (2) The entire surface is thinly coated with a plastic material that is water resistant but becomes brittle if left outdoors for long periods of time.
Or solidified slow-release fertilizer in large pellets sealed with a thin plastic film. (3) Large pellets of solidified slow-release fertilizer that are individually sealed and connected in a straight line at appropriate intervals to materials such as polyolefin films that are water resistant but become brittle if left outdoors for long periods of time.
