Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for fertilizing soil around a plant (such as a fruit tree).

[0002]

BACKGROUND ART When growing plants such as fruit trees in a stationary manner, nutrients in the soil may be depleted and the soil may become thin, and even when nutrients are not depleted,
Sometimes you want to actively promote plant growth. In such cases, fertilize the soil before planting the plant,
After that, fertilizer must sometimes be applied to the soil.

[0003] Fertilization of soil has been carried out, for example, by spreading fertilizer on the surface of the soil, or by cultivating the soil and mixing the fertilizer into the soil. In such fertilization work, it is necessary for an operator to carry a fertilizer bag and wander around a place to be fertilized while carrying a fertilizer bag, or to carry a hoe or the like with the fertilizer bag and mix the fertilizer while plowing the soil.

[0004] Such fertilization work is heavy labor even when it is performed on flat ground, but on flat ground, labor can be reduced by using agricultural machines. However, since agricultural machines are expensive, it is disadvantageous in terms of cost if fertilizer application is not performed frequently. Trees such as tangerines and peaches (fruit trees) and trees for timber are sometimes grown on sloping lands. However, it is difficult to work with agricultural equipment on sloping lands. There is. Fertilization on sloping land is more labor intensive than on flat terrain. Therefore, there is a demand for a method that can easily perform fertilization work on a slope.

The present invention has been conceived in view of the above circumstances, and can provide sufficient nutrition to plants, and can perform fertilizer application operations in a cost-effective and simple manner. That is the subject.

[0006]

DISCLOSURE OF THE INVENTION In order to solve the above problems, the present invention employs the following technical means.

[0007] That is, the fertilizer application block provided by the first aspect of the present invention is characterized in that a fertilizer containing a mineral-eluting component is held in an internal storage space of a water-permeable block main body.

This fertilizer application block is used by burying the block body in soil. When the block main body is buried in the soil, since the block main body has water permeability, moisture and rainwater in the soil enter the accommodation space. Since fertilizers containing mineral-eluting components are held in this storage space, minerals gradually elute from the fertilizer into the water, and are given to the soil together with the water, and are sucked up from the roots of the plants. It is consumed as nutrients for plants.

Therefore, if the soil is rich in minerals, it is absorbed from the roots of the plant and becomes a nutrient source for the plant. Therefore, by using the fertilizer block of the present invention, it is expected that the growth of plants will be good, and that fruits having a high sugar content will be obtained in fruit trees and the like.

[0010] By the way, in Japan, which has a lot of rain, calcium and magnesium in the soil are apt to flow out, so that acidification of the soil is likely to occur due to lack of calcium and magnesium, and the amount of minerals given to plants is reduced. Sometimes.

For this reason, if minerals such as calcium and magnesium are actively given to the soil as in the present invention, acidification of the soil is suppressed. Moreover,
Since the elution of minerals from the fertilizer occurs when rainwater or the like is supplied into the storage space, the amount of minerals eluted increases with an increase in rainfall. For this reason, in the fertilization block of the present invention, the mineral component is eluted from the fertilizer according to the amount of the mineral component flowing out of the soil, so that the mineral component is given more than necessary and the alkalinity of the soil is required. The acidity of the soil can be appropriately suppressed without becoming higher than the above.

Here, minerals include calcium, potassium, magnesium and iron. Examples of the components that elute such minerals (mineral-eluting components) include crushed oyster shells, crushed bones,
Pulverized coral, pulverized charcoal, and the like can be given. Of the mineral-eluting components exemplified, crushed oyster shells and bone meal are preferably used in consideration of cost and availability.

The fertilizer may further contain a microbial material. Examples of the microbial material used in this case include plant nutrients such as nitrogen compounds and carbon compounds by decomposing fallen leaves and carcasses of insects. Examples of the cells include produced cells, cells that secrete organic substances such as proteins derived from nitrogen compounds and carbon compounds, and cells that decompose organic substances that cause deterioration of water quality.

If such microbial material is included in the fertilizer, the water supplied to the storage space is purified and then flows out into the soil. If the microbial material is supplied together with the water into the soil, the water in the soil is removed. Water can be purified, or fallen leaves in the soil can be actively decomposed, so that the plant can easily absorb nutrients.

In the fertilizer, in addition to mineral-eluting components and microbial materials, oil residue (oilseed, soybean, cottonseed, flax, peanut, etc.) squeezed residue (oil cake), manure and sludge dry matter, etc. May be included.

The fertilizer is held in the storage space of the block main body, for example, in a lump or sand form. If the fertilizer is in the form of lump, replenishment of the fertilizer only needs to be put into the accommodating space, and the work becomes easy. Further, the fertilizer may be stored in the bag body, and the fertilizer may be replaced together with the bag body. In this case, the operation is easy. Further, even in the case of using the fertilizer in a lump, the fertilizer may be stored in a bag and the fertilizer may be replaced together with the bag. When bags are used, unnecessary fertilizers are removed together with the bags, so unnecessary fertilizers remain and accumulate in the accommodation space due to repeated replenishment of fertilizer. Can be avoided.

Here, various forms such as a sphere (ball), a rectangular parallelepiped, or a cubic can be cited as the form of the block. Further, as the bag, a bag having water permeability is used in order to ensure elution and outflow of other components such as mineral components and microbial materials. More specifically, those obtained by sewing nonwoven fabric, linen cloth, or cotton cloth or the like are preferably used, but when microbial materials are included in fertilizer, the bag is not corroded by the microbial materials. It is necessary to form a bag with such a material.

The block body is not particularly limited as long as it has water permeability. The block body is made of, for example, a mixture of cement and water mixed with crushed oyster shell or pumice stone. When crushed oyster shells are mixed, when entering and exiting water with the storage space,
Mineral content elutes from the ground oyster hulls and is provided to the soil. Further, since the crushed oyster shells and pumice stones have a small specific gravity, if these are used as materials, the weight of the block body can be reduced, and the burden of burying the block body can be reduced. Further, in order to increase the water permeability of the block body, a foam material may be mixed to form the block body.

Since such a block main body can be manufactured at a low cost by a known method, when the frequency of fertilization is low, it is obviously more costly to use a fertilizer block than to purchase and use an agricultural machine. It is economically advantageous.

According to a second aspect of the present invention, there is provided a method for fertilizing soil using the fertilizing block described in the first aspect of the present invention, wherein the method comprises the steps of: A fertilization method is provided, wherein the fertilizer is sequentially charged into a storage space while the block main body is buried in soil.

In performing this fertilization method, it is necessary to first bury the block body in the soil. This embedding work requires digging up the soil, accommodating a part or all of the block main body therein, and then burying the surroundings of the block main body with the soil, so that a complicated work is required. However, once the block main body is buried in the soil, the fertilization operation can be repeatedly performed by a simple operation such as putting fertilizer into the accommodation space. That is, since it is not necessary to dig up the soil or to spread the fertilizer after performing the fertilization work, the fertilization work after the block main body is buried is significantly simplified.

Moreover, the block body once buried is
If a material that does not easily corrode is used as a material for manufacturing the block main body, the block main body can be used for several decades without burying the block main body again. Therefore, when viewed comprehensively over a long span, it can be said that the fertilization method of the present invention has high workability. In particular, since the work of applying fertilizer to the soil around trees on sloping land is complicated, the fertilization work after burying the block body can be done by extremely simple work such as putting fertilizer into the storage space. Is big.

Other features and advantages of the present invention will become more apparent from the detailed description given below with reference to the accompanying drawings.

[0024]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be specifically described below with reference to the drawings.

One example of the fertilizer application block according to the present invention is shown in FIG. The fertilizer application block 1 shown in this figure has a block main body 2 and a fertilizer ball 3.

The block main body 2 has a columnar appearance, and has an accommodation space 21 having an opening 21 a in the upper surface 20.

The block body 2 is made into a slurry by mixing, for example, crushed oyster hulls 22, cement and water, and, if necessary, pumice crushed materials, gravel, pottery dust or fly ash. Thus, it is formed porous and has water permeability.
In order to increase the water permeability of the block body 2, the block body 2 may be formed by mixing a foaming material to form a slurry and molding the slurry. In addition, if a low specific gravity component such as pumice is mixed, the weight of the block body 2 can be reduced, and the burden of burying the block body 2 can be reduced.

The fertilizer ball 3 has a literally ball-like shape, and is made into a lump for easy handling. The fertilizer ball 3 is formed by mixing, for example, a mineral-eluting component, a fertilizer component, a microbial material, and other materials into a solid state. It has been.

Examples of the mineral-eluting components include crushed oyster shell, crushed bone, crushed coral, and crushed charcoal. When the mineral-eluting components exemplified above are used alone or in combination, when the mineral-eluting components come into contact with water, minerals such as calcium, potassium, magnesium and iron are eluted. In addition, among the exemplified mineral-eluting components, it is preferable to use a combination of crushed oyster shell and bone meal in consideration of cost, availability, and mineral-eluting properties.

Examples of the fertilizer component include known fertilizer materials such as oily residue (oil cake), manure, and dried sludge of oil and fat crops (rapeseed, soybean, cottonseed, flax, peanut, etc.). , There are no special restrictions on the type,
What is necessary is just to determine according to the kind of plant which grows in the soil used as a fertilization object, and soil condition.

Examples of the microbial material include microorganisms that decompose fallen leaves and carcasses of insects to produce plant nutrients such as nitrogen compounds and carbon compounds, and organic substances such as proteins derived from nitrogen compounds and carbon compounds. Or secretory cells that degrade organic substances that cause deterioration of water quality.

As shown in FIGS. 2 and 3, the fertilizer block 1 surrounds the plant such as the tree 4 with the block body 2 and aligns the upper surface 20 of the block body 2 with the surface of the soil 5 as shown in FIGS. It is buried in the soil 5 and the accommodation space 21
It is installed by storing the fertilizer ball 3 in the inside. More specifically, it is installed by digging up the soil 5, inserting the block main body 2 therein, filling the periphery of the block main body 2, and further charging the fertilizer balls 3 into the accommodation space 21.

When the fertilizer application block 1 is installed on the soil 5, since the block main body 2 itself has water permeability, the rainwater and the water retained in the soil 5 can enter the storage space 21. The water in the storage space 21 seeps into the soil 5 from the block main body 2.
In this case, if the crushed oyster shell 22 is included in the block body 2, minerals are eluted from the crushed oyster shell 22 when water passes into and out of the storage space 21. In addition, since the fertilizer balls 3 are stored in the storage space 21, the fertilizer balls 3 come into contact with moisture. When the fertilizer ball 3 comes into contact with water, at least a part of the fertilizer ball 3 is dissolved, so that the mineral eluting component, the fertilizer component, and the microbial material are dispersed in the water.

Further, minerals such as calcium are dissolved from the mineral-eluting components, and nutrients such as nitrogen compounds are dissolved from the fertilizer. Such minerals, nutrients, and microbial materials exude simultaneously when water exudes from the housing space 21 to the outside of the block body 2. If the diameter of each hole in the block main body 2 is large, the mineral-eluting components and the fertilizer components will seep into the soil 5 as they are, and the nutrients and mineral components will be dissolved in the soil 5.

In this way, nutrients, minerals and microbial materials are provided in the soil 5, and the nutrients and minerals are absorbed from the roots 40 of the tree 4. When the soil 5 is acidic, a part of the mineral is used for the soil 5 reforming. On the other hand, the microbial material given to the soil 5 has different functions depending on its kind, but it decomposes the fallen leaves and dead insects that constitute the soil 5 and turns it into nutrients. Secretes organic matter of origin or purifies water retained in soil.

Therefore, the fertilizer application block 1 of this embodiment
It is expected that the effect of enriching the soil 5 to make the growth of the trees 4 and the like healthy and to increase the sugar content of the fruits will be exhibited.

By the way, the fertilizer balls 3 housed in the housing space 21 are dissolved by water, and the constituents such as mineral eluting components, fertilizer components and microbial materials are consumed, so it is necessary to replenish the fertilizer balls 3 sequentially. However, such work only requires re-feeding the fertilizer balls 3 into the storage space 21.

As described above, the fertilizer application block 1 of the present embodiment
In the fertilization method using the soil, first, the block body 2 is
Relatively complicated work such as burying the block inside is forced, but once the block body 2 is buried in the soil 5,
Thereafter, the fertilizer application can be repeatedly performed by a simple operation such as re-feeding the fertilizer balls 3 into the storage space 21. That is, since it is not necessary to dig up the soil or sprinkle the fertilizer every time the fertilizing operation is performed, the fertilizing operation after the block main body 21 is buried is significantly simplified.

Moreover, the block body 2 once buried
If a material that is hard to corrode is used as a material for manufacturing the block body 2, the block body 2 can be used for more than several decades.
Can be used without being buried again. Therefore, when viewed comprehensively over a long span, it can be said that the fertilization method of this embodiment has high workability. In particular, since the work of applying fertilizer to the soil around the trees 4 and the like planted on the sloping land is complicated, the fertilization work after the block body 2 is buried is performed in the storage space 2.
There is a great merit that the fertilizer application operation can be performed by an extremely simple operation such as putting the fertilizer balls 3 into the fertilizer balls 1.

Next, another example of the fertilizer application block and the fertilizer application method will be described with reference to FIGS.

The fertilizer ball may be enclosed in the bag 30 'as in the previous embodiment. However, the use of the bag 30' facilitates the handling of fertilizer and the like. It is simpler to enclose in the inside of 30 'because it saves the trouble of forming into a ball shape. This bag body 30 'is connected to the lid 2B' via a string, a rope 6, or the like.
0 ′ is removed from the block body 2A ′,
It is configured so that the bag body 30 'and, consequently, the fertilizer 3' can be taken out from the bag 1 '.

The fertilization block 2 'may be installed on the soil so as to surround a tree planted on a slope or the like, as in the previous embodiment.
And may be arranged as shown in FIG. In the arrangement shown in these figures, only a lower end portion of each block main body 2A 'is embedded so that a plurality of floc main bodies 2A' are arranged in an annular shape in the original soil 5A '. An embankment is inserted into a region of each block main body 2A 'surrounded by a portion protruding from the original soil 5A' to form a growing soil 5B ', and a tree 4 is planted in the growing soil. To each block body 2A ', a lid 2B' to which a zipper fertilizer 3 'is connected by a string 6 or the like is attached so as to close the opening 20a'.

When the fertilizing block 1 'is arranged in this manner, minerals, fertilizers, microbial materials and the like are given to the cultivated soil 5B' by the action of rainwater and the like as in the above-described embodiment. And the growing soil 5B 'is enriched. Then, nutrients and the like in the growing soil 5B 'are absorbed from the roots 40' of the tree 4 ', which contributes to healthy growing of the tree, and suppresses acidification of the growing soil 5B'.

In the present embodiment, the block body 2
Since the cover 2B 'for closing the opening 20a' of A 'is provided, there is no possibility that soil or fallen leaves may accidentally enter the accommodation space 21'. Further, in the present embodiment,
Since the fertilizer and the like are stored in the storage space 21 'as the zipper fertilizer 3', the input of the fertilizer and the like is performed by a simple operation such as replacing the previously used zipper fertilizer 3 'with a new one. Performed and unnecessary fertilizers are stored in bag 3
