Abstract

PURPOSE:To improve the crops situation at a low cost and carry out the water supply for the growing in a greenhouse by collecting and storing rain fell onto the greenhouse in underdrains under the ground of the greenhouse, supplying the water to the soil in the greenhouse, occasionally draining the water in the underdrains and utilizing natural rainwater as in the case of raising in the open field. CONSTITUTION:Rainwater fell onto a greenhouse 1 is led to a headrace 2 with a trough and a water drain pulp 10 is operated to feed the rainwater to an underdrain 7 with a drain pipe 11. The rainwater is collected and stored in the underdrain 7 and simultaneously naturally made to flow down into underdrains 4, installed under the ground in the greenhouse and communicating with the underdrain 7. The rainwater permeates from through-holes 5 thereof into the ground to be sucked into a plant 12. Thereby, the water is supplied to soil 6 in the greenhouse 1. On the other hand, the drain pump 8, as desired, is operated to drain the water in the underdrain 7 from a drain pipe 9. As a result, the water is discharged to the outside of the site before or during the rainfall to always supply fresh water. Furthermore, the drain pipe 9 is extendedly installed on the outside of a cutoff film 3 or to a drain ditch, etc., to prevent the water from penetrating into the soil 6 in the greenhouse 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply method and device for greenhouse cultivation.

[0002]

2. Description of the Related Art Conventionally, in so-called greenhouse cultivation, it has been a common practice to install an underdrain corresponding to a ridge for water supply.

However, it is a common point that the pattern will drop if the greenhouse cultivation is continued, and as a measure against that, during the period of non-use, the ceiling part such as vinyl constituting the house is removed and exposed to rain. How to be done.

[0004]

However, due to the widespread use of materials such as hard plates and 5-year tension instead of vinyl in recent years, it has become impossible to open the ceiling part even in the summer when it is not used,
It was no longer possible to expose it to rain, and it was no longer possible to provide natural wind and rain to the soil in the house.

[0005]

Therefore, in the present invention,
The rainwater that collects on the house is collected by using the underdrain that is usually installed in the house, and this is supplied to the soil to improve the crop design. While storing and supplying the rainwater to the soil in the house by the underdrain provided in the basement of the house, the water in the underdrain is drained when desired. Secondly, a rainwater conduit is installed outside the house. At the same time, it is connected to the connecting part underground in the house, and while installing the underdrain at a desired position, a water supply mechanism to the underdrain connecting part is provided in the headrace, and a drainage mechanism is provided in the underdrain connecting part respectively. To do.

[0006]

The present invention will be described in detail below with reference to the embodiments shown in the drawings. 1 is a greenhouse used for so-called greenhouse cultivation such as a vinyl greenhouse, which may be a temporary facility or a permanent facility. 2 is a water conduit such as rainwater, is arranged facing one side of the house 1 in advance so as to be water guide the conductor waterway 2 by rainwater gutter that falls on house 1 (not shown). 3 is a blocking film, which can be buried in the ground outside the house 1 to block the inflow and outflow of water from other ground.

Numerals 4, 4, ... Are culverts buried in parallel in the house 1 at appropriate intervals, and desired ones such as unglazed clay pipes and pipes with through holes 5, 5 ,. To be done. The culverts 4, 4, ... Are installed under or along the ridges 6 or the like normally formed in the house 1 , but are not limited thereto.

The underdrains 4, 4, ... Are connected by an underdrain 7 which is embedded so as to intersect with them. The underdrain 7 the installation may be a house 1 out even within house 1, but if installed outside Howe <br/> scan 1 culvert 4,4, it is necessary to extend installed ...... 1 outside house. The underdrain 7 need not be an underdrain, but may be an open groove.

A drainage pump 8 is installed in the underdrain 7,
The drain pipe 9 is provided outside the blocking film 3 or to a drain groove or the like. 10 is a drainage pump provided in the water conduit 2.
The drainage pipe 11 reaches the underdrain 7. It is also possible to provide the water conduit 2 on the ground without providing the drainage pump 10 in the water conduit 2, and to conduct water to the underdrain 7 through the passage.
12 is a plant to be cultivated.

Next, the method and operation will be described. The rainwater that falls on the house 1 is introduced into the water conduit 2 by the gutter. The drainage pump 10 is operated to send the rainwater to the underdrain 7 through the drainage pipe 11. Alternatively, the rainwater in the headrace 2 is caused to flow down into the underdrain 7 through the passage.

The rainwater sent to the underdrain 7 naturally flows down to the communicating underdrain 4, 4, ..., seeps through its through holes 5, 5, ... or unglazed pores and permeates into the ground. Go, plant 1
2,12, ... However, the rainwater in the underdrain 7 and the underdrain 4, 4, ... Is sucked by the plant 12 or gradually lost due to transpiration to the ground.

Before it rains, the drainage pump 8 is activated,
Drain rainwater in the underdrain 7 and underdrain 4, 4, ... It rained, and the house 1 guided the gutters to the headrace 2
When the rainwater accumulates in the water, or when the rainwater reaches a certain amount, the drainage pump 10 is operated, or the rainwater is naturally caused to flow into the underdrain 7 by the passage. This rainwater flows into the underdrain 4, 4, ... Connecting to the underdrain 7, where it will leach into the ground.

Regarding the operation of the drainage pump 10 and the drainage pump 8, for example, when the water in the underdrain 7 is likely to rain, the drainage pump 8 is automatically operated by a push button or by detecting precipitation. The drainage pump 10 is activated when it rains and the headrace 2 reaches a certain amount of water, and continues until the water level does not rise to a predetermined position. The operation control can be controlled including automation. Of course it is.

[0014]

EFFECTS OF THE INVENTION According to the present invention as described above, firstly, the rain falling on the house is collected and stored, and the rainwater is supplied to the soil in the house by the underdrain provided in the basement of the house. Water is drained when desired, and secondly, a rainwater conduit is installed outside the house, while it is connected to a connecting part underground in the house, and a culvert is expanded and installed at a desired position.
Since the headrace was equipped with a water supply mechanism to the underdrain connection and a drainage system was installed in the underdrain connection, rainwater, and also fresh rainwater, was supplied to the soil in the house, and it was used for placing it in the open field for cultivation. It is possible to supply rainwater in a close condition, the pattern is significantly better than any improver, yield is increased, resistance to pests and diseases is prevented, and the damage can be prevented. ..

Of course, the facility can be used at a low price because the existing installation can be used and the investment cost can be suppressed by simply providing a water supply system for a normal house with a water conduit and a water passage mechanism such as a gutter. It is highly practical because it can be manufactured at low cost.
