Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for cultivating long fruit using a trencher.

More specifically, the present invention relates to the process of planting and growing long vegetables in a cultivation bed that is formed by digging and backfilling a trench using a trench excavator, and the process of planting and growing long crops at the base of the cultivation rows. , by repeating the harvesting process in which a trench is excavated and shaped using a trench excavation machine, and the roots of long plants are dug out in the trench, and the process in which the excavation trench is backfilled is repeated. This invention relates to improvements in the method of cultivating long crops in continuous cultivation.

[Prior Art] As shown in Fig. 1, cultivation of long grains is usually carried out using an endless chain type excavation device 1 attached to a machine body a that is towed by a tractor or self-propelled.
Using a trench excavator A equipped with By running the machine a so that the downward stroke side 10a of the machine 10 faces forward in the traveling direction (the direction indicated by the double line arrow in Fig. 1), the excavation chain 10 is moved as shown in Fig. 2. We excavate in a deep groove shape with a width corresponding to the excavation width of that,
In addition, the excavated soil is sent directly into the groove W formed at the rear in the direction of movement of the excavation device 1 by the excavation chain 10 and backfilled (first
3), as shown in FIG. 3, a cultivation bed B is formed which is deeply cultivated in a groove shape with a width corresponding to the working width of the excavation device 1, and then the cultivation bed B is Wall surface b of groove W when long seedlings are planted, fertilized and grown, and groove W is excavated using excavator 1 to form cultivation bed B for long seedlings R.
Then, when the long root R has grown to a predetermined size, a trench excavator with a wide excavation width is used to excavate the long root R. As shown in FIG. 5, a worker who excavates a trench Y with a width wider than the trench W forming the cultivation bed B, and who enters the trench Y, cuts the roots R into the trench Y. A trench excavator that harvests by digging inside, and excavates and shapes the trenches Y used for this harvesting work along the long cultivation rows. During the return stroke, as shown in FIG. While dredging the excavated soil S that has been dug up on the side of trench Y into trench Y by switching the
Backfilling is performed by pressing with the running wheels 12 installed on the body a of the trench excavator A. By repeating each of these steps, continuous cultivation is carried out over a long period of time.

[Problems to be Solved by the Invention] By the way, in this method of cultivating long vegetables using a trench excavator, a cultivation bed for long plants to be cultivated in the next year is formed in the field using a trench excavator. When the cultivation bed overlaps with the area where the excavation trench Y excavated for harvesting in the previous year is backfilled, the long potatoes planted on the lapped cultivation bed become irregularly shaped. It grows thick and thick,
Not only does it have no commercial value even if it is harvested, but when a trench is dug next to the planting row for harvesting, it gets caught in the drilling chain of the drilling equipment and breaks up. There is a problem with growing too much food and not being able to harvest it.

The present invention was made in order to solve this problem, and the cultivation bed formed using a trench excavator backfills the excavation trench formed in the previous year for harvesting long grains. Even if the long potatoes are planted and grown in the cultivation bed, they will grow into straight rod shapes with high commercial value, and a groove excavation machine will be used to dig trenches at the roots of the planting rows. The purpose of the present invention is to provide a new method for cultivating long materials that does not get caught in the excavation chain of the trench excavation machine and crushed during excavation and shaping.

[Means for Solving the Problems] The present invention has been completed based on knowledge obtained through various studies and tests in order to solve the above-mentioned problems.

In other words, when a cultivation bed is formed using a trench excavator to plant long crops, the cultivation bed wraps around the area where the excavation trench that was dug and shaped for the harvest of long crops was backfilled in the previous year. The problem mentioned above is that the excavated soil returned to the excavated trench is compressed tightly into the trench by the wheels of the trench excavator or the wheels of the tractor that pulls the trench excavator. Even under such conditions, the compaction due to treading pressure is limited to about 30 mm from the soil surface at most, and in areas deeper than that, the excavated soil remains in the swollen and soft state it was in when it was put into the excavation trench. In addition, if a cultivation bed is formed in the backfilled excavation trench by using a trench excavation machine to excavate the trench and backfilling with excavated soil for planting long crops, There is a hard wall surface at the top end of the cultivation bed, but from the middle part to the bottom end in the depth direction of the cultivation bed, where the main part of the roots of long plants grows and enlarges, there is a hard wall surface that guides the elongation of the roots of long plants. It was found that this occurs because the roots are free to extend in all directions due to the absence of a hard wall surface. From this, the excavation trench that was excavated and formed during harvesting work is dug by the soil removal plate or soil removal auger installed on the machine body, using the operation of the trench excavator on the return stroke. When backfilling the soil, do not backfill in one step, but only half or three times the amount.
The excavated soil is backfilled in several steps at a rate of approximately 1/2 of the amount, and at each backfilling step, the excavated soil is compacted back into the trench using a compression wheel installed on the machine. When the trench was backfilled and a cultivation bed was formed the following year using a trench excavator, long potatoes were planted, cultivated, and fertilized.The long potatoes grew into a predetermined straight rod shape. This is due to the fact that even if a sampling groove is excavated at the location, there are no long pieces that can be crushed by getting caught in the excavation chain.

From this, in the present invention, as a means to achieve the above-mentioned object, a process of planting, growing and fertilizing long crops on a cultivation bed formed in a field by digging and backfilling a trench with a trench excavator. , a harvesting process in which a trench for digging is formed by a trench excavator at the root edge of the cultivation row for long grains, and the roots of the long grains are dug into the trench, and the trench for digging is carried out several times. The present invention proposes a method for cultivating long vegetables, which is characterized by cultivating long plants by repeating the backfilling process of dividing and sequentially backfilling, tightening, compacting, and backfilling.

[Example] Next, an example of implementation will be described in detail with reference to the drawings.

First, put the trench excavator A into the field where long potatoes are to be cultivated, and as shown in FIG.
By moving the soil toward the front in the direction of travel, the groove is excavated and the excavated soil is backfilled into the groove to form a cultivation bed B as shown in Fig. 3, and long seedlings are planted in the cultivation bed B. .

Next, when this long root R has grown as shown in FIG. The machine A excavates a trench Y for digging as shown in Fig. 7, and a worker enters the trench Y and excavates the roots R of long plants into the trench Y to harvest.

Next, when this harvesting process is finished, either use the soil removal auger 11 installed on the body of trench excavator A, or use the auger 11 installed on the front end of the body of trench excavator A as shown in Figure 8. Adjust the elevation of the earth removal plate 2,
Adjust the height to the height at which about half to one-third of the excavated soil S accumulated on the sides of the trench Y will be dredged into the trench Y, and in this state, run the machine as shown in Figure 8 to remove the excavated soil. S is returned to the groove Y, and at the same time, half to one-third of the excavated soil returned to the groove Y is tightened using a compression wheel 3 equipped on the machine, and then the same operation is performed. Then, the remaining excavated soil is sequentially returned to the trench Y, compacted and compacted, and this operation is repeated to backfill the excavation trench Y.

Next, in the following spring, a long seedling cultivation bed B is formed using a trench excavator A as shown in FIGS. 1 to 3, and long seedlings are planted there and fertilized and grown.

[Function] As mentioned above, when cultivating long plants according to the method of the present invention, the long plants that have been planted and grown on the cultivation bed B, which is formed by digging and backfilling the trench W with a trench excavator, are placed next to the roots of the long plants. , a groove Y for excavation is excavated and formed by a groove excavator, and the groove Y for excavation is harvested.
When the cultivation bed B was formed by backfilling the area while excavating the groove W with a trench excavator, the cultivation bed B came to have hard walls b on the left and right sides, and the roots of the long ones R will grow into a straight rod shape.

[Effects of the Invention] As explained above, according to the method of the present invention, the excavation groove Y excavated by a trench excavator to dig out the roots R of long things, after harvesting the roots R of long things,
By backfilling the excavation trench Y to the bottom firmly, it is possible to shape it by backfilling while excavating the trench with a trench excavator for cultivating long crops in the next year. Even if a cultivation bed B is formed in a position that overlaps with the excavation trench Y formed and backfilled in the previous year, the cultivation bed B will have a wall surface b of the trench W when forming the cultivation bed B. As the roots R of the long plants planted on the cultivation bed B grow into a straight rod shape, the cultivation bed and the trench for digging are made using a trench excavator. In addition to the cultivation mode of shaping, it is now possible to continuously cultivate long potatoes in the same field and grow their roots into straight rod shapes.
