Description

Methods for improving the growing environment of greenhouse crops

[0001] The present invention relates to a method for improving the growth environment of house-grown crops, and more specifically, to a novel method for improving the growth environment of house-grown crops that can dramatically solve various problems such as high vulnerability to moisture, salt phenomenon, and weak root growth in crops grown indoors such as houses.

[0002] Crops grown indoors, such as in vinyl or glasshouses, often experience poor growing conditions due to poor ventilation. Furthermore, the frequent use of agricultural machinery in agricultural fields can compact the soil, creating a hard, compacted layer of soil approximately 20 to 40 cm deep. Because the soil pores in this layer are very small, this layer significantly reduces soil permeability and drainage, creating a poor growing environment for crops and ultimately leading to reduced crop yields.

[0003] Especially in soils with a hard, low-permeability layer of hard loam beneath the soil layer, water often pools and drainage is difficult, making indoor crops highly vulnerable to moisture damage. This also makes it difficult to supply oxygen to the soil, potentially leading to root system deprivation and a deteriorating growing environment.

[0004] Therefore, it is clear that the most important elements for crop growth are water and air, so it is very important to create an environment that provides the crops with an appropriate amount of water and oxygen.

[0005] Up until now, there have been various methods for supplying water to crops, such as furrow irrigation, hose irrigation, drip irrigation, fountain irrigation, sprinkler irrigation, mist irrigation, and subsurface irrigation, but all of these methods spray directly on the leaves of the crops or on the surface of the ground so that it flows down through the cracks in the soil and is supplied to the roots. Therefore, if water is sprayed on the crops or the surface of the ground while leaving the hardpan layer as it is, a lot of water is consumed due to evaporation. Above all, since the structure is such that the moisture comes into direct contact with the leaves or fruits of the crops, it creates an environment very suitable for mold and insects to live in. In addition, due to the high humidity, the epidermis of the fruit cracks or is damaged due to repeated expansion and contraction due to moisture, which causes a heat phenomenon.

[0006] Furthermore, in cases like the above, water usually exists only on the surface, so crop roots tend to turn toward the surface in search of water, preventing them from forming deep, wide roots. This hinders the stable growth of crops and negatively impacts fruit growth.

[0007] Moreover, the water remaining on the surface contains nutrients, which causes salinity problems, and the water that flows off the surface and drains into rivers can cause environmental pollution such as eutrophication.

[0008] Of course, among the water supply methods, there are also underground irrigation methods that supply water directly into the ground rather than on the surface. This method supplies water by placing a drip hose near the roots or forming a water pocket, but this has the disadvantage of causing unbalanced root growth due to uneven water supply.

[0009] Also, as mentioned above, what is important for crop growth is not only water, but also ensuring that the soil is sufficiently supplied with oxygen so that the roots can absorb enough oxygen, and also ensuring that the gaps between the soil and the pores are filled with enough oxygen, which increases the contact area between the roots and oxygen and enables a uniform supply of oxygen.

[0010] However, until now, organic and comprehensive research on the characteristics of water, oxygen, and soil has not been conducted for all indoor crop cultivation, so the growing environment for greenhouse crops has inevitably become poor, and as a result, it is impossible to expect improvements in crop yields, fruit yields, and sugar content.

[0013] 2. Republic of Korea Patent No. 10-1054882

[0014] The purpose of the present invention is to provide a method for improving the growth environment of new house-grown crops, in which the air supply pipe of a subsoil breaker is inserted into the ground around the crop while the crop is transplanted into the soil, and high-pressure air pressure is emitted at predetermined depth levels to finely break up the soil around the roots, thereby allowing oxygen in the air inside the room to flow into the ground, and sufficient pores are formed between the soils so that oxygen can remain in the pores for a long time, thereby supplying sufficient oxygen to the roots, and the air supply pipe of the subsoil breaker is removed, and a water pipe capable of supplying water is inserted into the formed through-hole, and then water flows from the bottom of the through-hole formed by the subsoil breaker to form a layer of water under the roots, so that there is almost no water inside the room and a certain layer of water exists only in the ground below the roots of the crop, thereby inducing the crop to send its roots toward the water under the roots and allowing the crop to send its roots deep into the ground, thereby ensuring stable growth of the crop and providing sufficient water, oxygen, and nutrients, and minimizing moisture in the air inside the room, thereby preventing insects, mold, The purpose is to create the most desirable environment for crop growth by enabling them to escape from heat and cold phenomena.

[0015] In order to achieve the above-described purpose, a method for improving the growth environment of house-grown crops according to an embodiment of the present invention comprises the steps of: using a subsoil crusher to finely break up the soil around the crop or the area where the crop is to be planted while the crop is transplanted into the soil or before transplanting, and using an air supply pipe or a through-hole drilling tool of the subsoil crusher to form a plurality of through-holes at even intervals deeper than the root depth of the crop around the crop or the area where the crop is to be planted; inserting a water pipe connected to a water tank into the through-holes so that it extends to the ground; and supplying water to the water pipe so that the water flows out from the bottom of the through-holes, thereby forming a wide water-accumulating layer under the roots.

[0016] According to an embodiment of the present invention, in the step of forming a through hole through the air supply pipe of the subsoil crusher, high pressure air is sequentially supplied to the air supply pipe at predetermined intervals from a shallow depth to a deep depth to form a through hole and at the same time crush the soil of the ground into small pieces to form many pores.

[0017] The above-described effects of the present invention include inserting the air supply pipe of the soil breaker into the ground around the crop while the crop is transplanted into the soil, and emitting high-pressure air pressure at predetermined depth levels to finely break up the soil around the roots, allowing oxygen in the indoor air to flow into the ground, and also forming sufficient pores between the soil so that oxygen can remain in the pores for a long time, thereby supplying sufficient oxygen to the roots.

[0018] In addition, the air supply pipe of the soil crusher forms a penetration hole while finely breaking up the soil, and when a water pipe capable of supplying water is inserted into the penetration hole and water is supplied, a water retention layer is formed under the roots, which guides the roots downward, causing them to grow deep into the ground.

[0019] In this way, the present invention is a very useful invention that can create the most desirable environment for crop growth by providing sufficient water, oxygen, and nutrients as well as stable growth of crops, and minimizing moisture in the indoor air, thereby preventing insects, mold, and heat-related phenomena.

[0026] Hereinafter, preferred embodiments of a method for improving the growth environment of house-grown crops according to the present invention will be described in detail with reference to the attached drawings.

[0027] FIG. 1 is a reference diagram showing a step of finely crushing the soil around the roots by firing high-pressure air pressure at predetermined depth levels using a soil crusher in the present invention, wherein (I) is a shallow depth, (II) is a middle depth, and (III) is a deep depth.

[0028] First, it should be noted that, among the drawings, identical components or parts are indicated by identical reference numerals, where possible. Furthermore, in describing the present invention, detailed descriptions of related known functions or configurations are omitted to avoid obscuring the gist of the present invention.

[0029] The method for improving the growth environment of house-grown crops of the present invention comprises the steps of: using a subsoil crusher to finely break up the soil around the crop or the area where the crop is to be planted while the crop is transplanted into the soil or before transplanting, and using an air supply pipe (113) or a through-hole drilling tool of the subsoil crusher to form a plurality of through-holes (140) at even intervals deeper than the root depth of the crop around the crop or the area where the crop is to be planted; inserting a water pipe (220) connected to a water tank into the through-hole (140) so that it reaches the ground; and supplying water to the water pipe (220) so that the water flows out from the bottom of the through-hole (140), thereby forming a wide water-pileup layer under the roots. At this time, the water pipes (220) may be formed in a plurality of forms spaced apart by a water supply pipe (210).

[0030] In the present invention, the step of using a soil crusher to finely break up the soil can be used even when the crop is transplanted into the soil, but the soil around the crop or the location where the crop is to be planted can also be finely broken up in advance using a soil crusher before the crop is transplanted into the soil.

[0031] At this time, a through hole (140) must be formed in the finely crushed ground to insert a water pipe (220). At this time, the through hole (140) can be formed using a separate through hole drilling tool, but it is preferable to form the through hole (140) using the air supply pipe (113) of the subsoil crusher. This is because the air supply pipe (113) of the subsoil crusher forms the through hole (140) simultaneously with the process of crushing the hard layer and finely splitting the soil, thereby increasing the efficiency of the work.

[0032] At this time, it is preferable that the penetration hole (140) be formed at a depth of at least 50 to 100 cm around the crop or the location where the crop is to be planted. At this time, the depth may be shallower than 50 cm or deeper than 100 cm. Naturally, this depth may vary depending on the crop.

[0033] It is preferable that the water pipe (220) inserted into the above-mentioned through hole (140) be inserted so that it reaches the bottom of the through hole (140). This is because water flows down from the end of the water pipe (220), and the height of the water pipe (220) must be the same or similar so that a water retention layer (W1) can be formed under the roots of the crop.

[0034] In the step of forming a through hole (140) with the air supply pipe (113) of the above-mentioned subsoil crusher, it is desirable to form the through hole (140) by sequentially supplying high pressure air to the air supply pipe (113) at predetermined intervals from shallow depth to deep depth, and at the same time, to finely crush the soil of the ground to form many pores so that the air inside the vinyl house or glass house can permeate well into the soil and remain in the pores for a long time. In this case, the predetermined interval varies depending on the condition of the soil, but is preferably 10 to 30 cm.

[0035] The subsoil crusher (110) used in the present invention comprises a compression body (111) having a handle (112) on the outer periphery and a space formed where compressed air is introduced and stored, an over valve (not shown) provided inside the compression body and discharging the compressed air into the interior of the compression body according to the pressure of the compressed air introduced through the air supply pipe, a flow control valve (not shown) for discharging the compressed air into the interior of the hardboard layer while controlling the amount of compressed air stored inside the compression body during subsoil crushing, a compressor (120) coupled to the flow control valve and inserted into the hardboard layer for subsoil crushing to supply compressed air to the soil, and an air supply line (130) connected to the compressor and connected to the over valve and the flow control valve to introduce air into the interior of the compression body. Of course, it is obvious that the subsoil crusher used in the present invention is not limited to the subsoil crusher having the structure mentioned above or the structure illustrated in the drawings.
