Description

[Detailed Description of the Invention] In recent rice cultivation, in order to improve the drainage of rice fields and improve rice yields (deep drain pipes are installed in the soil layer of two rice fields),
Water is drained from the bottom of the rice fields to make them dry.

On the other hand, due to the frequent use of large agricultural machinery, the field surface becomes compacted and compacted, and the soil layer gradually becomes hard.

The upper part of this hardened soil layer is carried and plowed with a tiller (−
As this process is repeated, the two soil layers form a cultivated soil layer, a hard soil layer that has not been plowed and has been compacted, and a soft soil layer that retains the original soil quality below. Become.

The existence of this hard soil area makes it difficult for water to pass through, making it easy to produce five-colored water, and the air circulation to the soft soil area is also poor. ) Facilities should also reduce their effectiveness (-).

The present invention uses a drilling rod to forcibly penetrate the hard soil area that is unavoidably formed. At the same time, the soft soil of the dedication area was moved and discharged to the top of the Murakami area and a spot survey was carried out (in the two vertical holes or near the vertical hole (=fertilizer ItfM spread, bending water to the hard soil area and the dedication area). The purpose is to provide a deep plowing treatment method for rice fields that improves the aeration and fertilization effect to actively grow rice and improve yields.An example of implementation is shown below with reference to the attached drawings. That's right.

In the soil layer of the rice field, the upper tilled soil part (1), the middle layer hard soil part (2), and the lower layer soft soil part (3) penetrate through the hard soil part (2) from the rice field surface. The hard soil of the hard soil part (2) of the middle layer and the hard soil part (3) of the offering part (3) (= having the quality of reaching
) is used to sequentially reach the central and upper parts (3) (= The vertical holes (5) at the depth are drilled in a scattered state (two holes are drilled, and the perforated body (4) is pulled up (the hard soil in the hard soil part (2) and the soft soil in the soft soil part (3) are captured from the second one). Then pull the soil up to the upper part of the cultivated soil (1), which is hard and soft soil (double-moving soil removal), and at the same time (double vertical hole (5) or near the vertical hole (5) (2) apply appropriate fertilizer. It is characterized by dispersing.

The perforated body (4) in the drawing has a U-shaped cross section (opening rtj 4
At the same time, form a vertical hole (5) with a depth of about 2 crfL (= inside this U-shaped inner cavity (2) to be able to trap hard soil or soft soil, and - side (in the case of the drawing) is on the back)
The U-shaped opening of the is used as the earth removal part (4a), and the lower end
6), and a horizontal rod (7) that closes the opening (= right above the piercing blade (6)) is attached, and a cutting blade (8) is formed on the lower edge of this horizontal rod (7) to make a hole. Body (4) (= Good separation of hard and soft soil to be captured (2) is shown in the figure, but U-shaped (
The lower end of the pipe-shaped rod (
The upper back surface (two excavation parts (4a)
It is also possible to have a structure in which .

In short, it is sufficient to adopt a structure that can capture and remove soft soil effectively.

The fertilizer application device (d) in the drawing is equipped with a fertilizer storage chamber (9) and a perforator (C) (described later), and this fertilizer storage chamber (9) (two spreading pipes (II) are installed vertically, and two fertilizers are placed in the appropriate place). An adjusting device (11) is provided to drop the adjusting device (11) intermittently by an appropriate amount, and the lower end of the adjusting device αυ is positioned at the rear (=position) of the perforated body (4), and the traveling towing vehicle (
For example, the forward speed of step a) and the downward movement of the adjustment device are correlated so that, for example, granular fertilizer can be fed as much as possible through the vertical holes (5) (-
It is desirable to configure it so that it can fall directly into it.

The depth of cultivating the soil with a cultivator is usually 15 to 20 cIr.
Since the hard soil area (2) below this cultivated soil area (1) is approximately 10 to 20 cTL, if the vertical hole (5) is drilled to a depth of approximately 30 to 60 cIn from the river surface, it will be a sandy soil area. (2), so the length of the perforating rod (4) is approximately 30 to 60 cm.

Drilling work is carried out using a moving towing vehicle (a) such as a tractor or tracked vehicle.
) (2-3 point link mechanism or other supporting device (b) holds the drilling machine (C), and lifts and lowers the drilling rod (4) from the lifting device (2) of this drilling machine (C) during drilling. The drilling tool (2) is provided so that the drilling body (4) moves backward in the horizontal direction, and when the drilling body (4) is pulled up, it returns to its original position (2) and repeats the drilling operation again. Designed with

Figures 1 and 3 (the double arrow ■ indicates the lifting of the drilling rod (4) by the lifting device (second), the arrow ■ indicates the lifting of the drilling rod (4)
4) indicates the return movement to the original position, and the arrow mark indicates that the drilling operation is repeated again.

Recently, large agricultural machinery such as tractors, cultivators, rice transplanters, harvesters, and combines have been widely used.

For this reason, a hard soil section (2) is formed below the cultivated soil section (1) (as mentioned above, the hard soil section (2) is compacted by these agricultural machines, and its thickness is usually about 10 to 20 crrL). be.

This hard soil area (2) is only hard (2), resulting in a dense soil layer with extremely poor water flow and ventilation (2), and the growth of rice (2). 2), which results in poor establishment and growth, which causes the rice to fall over and become immature, significantly reducing the yield.

In other words, no matter how much you plow the surface tilled soil (1), as long as there is a hard top layer directly below it, you will not be able to expect a good harvest, and it is important to avoid the drawbacks of poor drainage in the underground drains installed to improve yields. I could not do it.

The present invention proactively (= solves) this drawback, and since the formation of hard soil parts is unavoidable, it is the opposite (= completed hard soil parts (
Forcibly using two perforation rods (Deep cultivation by drilling a large number of vertical holes, and at the same time fertilizing the vertical holes or the vicinity of the vertical holes.) As mentioned above, the soft soil part (3) (double vertical holes (5) of two consecutive depths are drilled through the hard soil part (2) directly under the plowed upper part (1)) of the drill rod ( 4) is used to drill holes from autumn to spring after harvest (two times scattered over the entire rice field (= hole is drilled first) (7)
), fresh air infiltrates straight to the bottom of the vertical hole (5), and this air flows through the vertical hole (5) into the soft cultivated soil (
1) and the soft soil part (3) as well as the hard soil part (2), making the air supply to the entire soil layer extremely good, and especially (
Bivalent upper part (2) (For two, air is supplied from the top, side, and bottom, so even if it is a hard layer, it is much better than the conventional one (
= good (two air supply is done (= becomes).

Of course, water flow is the same (very good), and underdrain drainage is also extremely effective.

In addition, the perforation rod (4) has a length that penetrates the hard soil part (2) from the rice field to reach the soft soil part (3). Since it is possible to capture soil and soft soil, when the drilling rod (4) that has completed the drilling work is pulled up upward C2, the captured hard and soft soil will be removed from the drilling rod (4). (
1) It will be pulled upwards.

In this case, if the length of the drilling rod (4) is short, the soft soil can be captured (
9) ■ may also be a small amount of C2.

This pulled up hard and soft soil can be easily moved (from the second soil removal section (4a) onto the cultivated soil section (1) (: the soil removed That (=
Become.

This is a hard soil area that could not be cultivated until now (2)
Since the hard and soft soil in the soft soil area (3) below is moved upward, the result is the same as plowing.

This deep plowing further promotes the aeration and water permeation effects mentioned above, which is an excellent feature that improves the yield accordingly.

In particular, soil removal from the drilling rod (4) is performed under various conditions (2). Body (4) 1

Become.

In the spring, the upper layer is cultivated, but the sandy soil below it (2) (
It is common for the two vertical holes (5) to be scattered (a good result is to increase the water permeability from below).

Next, irrigation water is introduced and rice is planted (= Even if the vertical hole (5) in the hard soil area (2) is blocked by mud, it is different from the original hard soil area (2). Therefore, it is necessary to maintain sufficiently good ventilation and water permeability.

Moreover, the roots of rice located in the vertical hole (5) (2) can extend out from the vertical hole (5) into the deeply cultivated soft soil area (3), which further ensures root growth and establishment. The rice will grow into rice that is easy to harvest and will not fall over even when the season comes.

These synergistic effects allow the rice to grow well and exhibit excellent features that can greatly improve yields.

This also applies to fertilizer application; when the perforating rod (4) perforates the vertical hole (5), the perforation rod (4) simultaneously pierces the vertical hole (5) or near the vertical hole (5) (= appropriate fertilizer is spread). Exactly vertical hole (5) EThe spread fertilizer is straight (two vertical holes (5)
) to the bottom of the slanted upper part (1) through the vertical hole (5).
Fertilization permeates not only the soil and soft soil areas (3) but also the hard soil areas (2), which was impossible in conventional methods, so the fertilization effect on the entire soil layer is extremely good.

At this time, the fertilizer is not spread just above the vertical hole (5), and the fertilizer is not spread just above the vertical hole (5).
5) Due to the presence of vertical holes (5), fertilizer seeps from the sloped upper part (1) even in the vicinity of the hard soil area (2) through the vertical holes (5).

Since it permeates into the soft soil part (3), the fertilization effect is spread throughout the soil layer, and the fertilizer is sufficiently absorbed by the expanding roots of the rice, which improves the growth of the rice and further enhances the synergistic effect. This is a deep-tillage treatment method that can improve yields in rice fields and has excellent features.
