Description

[Detailed description of the invention] The present invention relates to a soil disinfection device and the device.

−4. Every year in greenhouse cultivation of carnations etc.−
This requires so-called planting, which disinfects the soil from pathogens and other germs at least once.

This planting work is usually done by one of the following methods: steam disinfection, chemical disinfection, or hot water disinfection.

The steam disinfection method sterilizes and disinfects the soil by spraying steam onto the soil, and because it generates high-temperature steam and sprays it with a pump, it requires a large set of equipment and equipment. Therefore, it is not only expensive as a complete device, but also requires a lot of effort to move and spray the device during use, resulting in a lot of inconvenience and inconvenience as a whole.

In addition, the chemical disinfection method involves spraying or dropping a disinfectant solution onto the soil in the form of a mist, which causes significant chemical damage to workers and surrounding crops during the process, and the chemicals are also expensive and require large quantities. I need.

The hot water disinfection method involves embedding an endless metal pipe in the soil to circulate hot water, which heats the soil and disinfects it.
Because the disinfection is carried out on the moon, the greenhouse is hot and heavy pipes must be handled and buried underground, which not only requires labor and time to prepare for disinfection, but also takes a considerable amount of time to complete. It takes time, and furthermore, it requires time and effort to dig out and carry out the pipes after disinfection and leveling the ground afterwards, and it also costs a lot of money.

In view of the above circumstances, the present invention provides a disinfection method and a device therefor that can eliminate the drawbacks of the conventional methods described above. Soil that requires disinfection of high-temperature water spout pipe equipment! The method is characterized in that the inside of the soil is buried, and the high-hot water jetting pipe device is connected to a high-hot water supply source via a hose, and the high-hot water is discharged into the soil to perform heat disinfection at a high temperature.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to a high-temperature water ejection pipe device shown in the accompanying drawings.

First, the present invention provides soil disinfection equipment such as the one shown in the figure on soil that requires disinfection at a depth near the soil surface, for example, underground.
Bury at a depth of ~10 cIIL.

This soil disinfection device consists of several sets of four discharge pipes 1 having a required length, which can be connected by connecting short pipes 2.2 to both ends of each of them at regular intervals.

The width is appropriately determined so as to cover the required area, and the groups of these short tubes 2 are arranged into plate tubes 3 at regular intervals.
A manually operated valve 4 is interposed between the branch pipes 3, and a high-hot water supply connecting pipe 5 is connected to the branch pipes 3.

The discharge pipe 1 has discharge holes 9 formed downward at regular intervals.

A hose 6 such as a rubber hose is connected to the supply connecting pipe 5.
This hose 6 is connected to a high-temperature water supply source 8 such as a boiler via a drain extractor 7 .

Thus, the soil disinfection device, the hose 6, the drain extractor 7, and the high-temperature water supply source 8 can be separated for convenient transportation or burial work. At the same time, the high-hot water supply source 8 is driven to discharge high-hot water from the discharge hole 9 of each discharge pipe 1 into the soil for a certain period of time.

As a result, the high-temperature water infiltrates into the soil and kills diseased bacteria and other germs in the soil.

At the same time as this disinfection action (ξ As high-temperature water infiltrates into the soil and flows downward, salts and other residual components accumulated in the soil are washed away and penetrate deep into the ground, and such salts, etc. are Runoff from the soil.

The following table shows the implementation data of the present invention, and shows the greenhouse operated by the inventor (line soil area 112.5 m2, length 25 m, width 4
．． 5 m), the length of the discharge pipe 1 of the soil disinfection device is approximately 25 m, and the mutual interval is 20 m.The diameter of the discharge pipe 1 is approximately 2371 m.
m, the length of short pipe 2 is approximately 60α, and its diameter is approximately 2571 m.
The length and total width of each greenhouse is approximately 4.5 m, and the time elapsed in the center of each of 20 grid-like sections, which are made by dividing the soil in the greenhouse into 5 vertically and 4 horizontally. The results of subsequent soil temperature measurements are shown.

In Table 1, boiling water is spouted sequentially every 30 minutes by opening and closing the pulps 4, 4 for each set of short pipes 2 of the disinfection device,
Similarly, Table 2 is repeated twice every 20 minutes, and once again.
It was disinfected every 0 minutes.

According to this table, all results exceeding the disinfection temperature standard of 60°C were maintained even after about 6 hours.

According to the method of the present invention described above, when disinfecting the soil in a greenhouse for replanting, the disinfection is carried out using the most preferable boiling water without causing the gas damage caused by chemical disinfection method ζ, and the entire apparatus is relatively compact. Since it uses simple, small-diameter pipes, it is lightweight overall, making it extremely easy to transport and handle, and it is useful when replanting is required in a greenhouse during hot seasons. The lightweight and easy-to-handle device is buried in the soil, reducing the need for digging, and since hot water is released into the soil, soil disinfection is as direct as steam disinfection or chemical disinfection. This has the effect of cleaning salts and other fertilizer components accumulated in the soil.

Since the time required to disinfect the soil is extremely shortened, work efficiency is high, and fuel costs are also extremely reduced, resulting in savings.
