A method of planting seedlings in a field, a method of partially cultivating a field with a narrow width, and planting seedlings in the cultivated portion are known.

[0003]

Of the above-mentioned known planting methods, the first method is a method which is conventionally and conventionally performed most often, and after a field is roughened by a rotary tillage device, In the dry field state or flooded state, the soil is crushed by the rotary tillage device, and thereafter, flooding the field and scratching the entire cultivated layer requires a great deal of labor, and the soil is kneaded to a deep layer. Together, there was no void in the soil and the planting operation had to be done separately. The second method is
In the field at the time of planting, there are traces of crawlers and pits of the combine at the time of harvesting, which lacks uniformity, and because there are many old plants and weeds, these are obstacles, and they are extremely deep or shallow plants. Floating seedlings and poor growth occur. Furthermore, the third
In the method of (1), it was difficult to stand and maintain the planted seedlings because the soil in the cultivated portion of the planting site was not sticky.

[0004]

The present invention SUMMARY OF THE INVENTION may, for waterlogging and soil caused the field plowing while the膨軟, shallow surface layer of 該土 soil

The fertilizer tank 40 comprises a rotating disk 39 which is inclined forward of the discharge port and has a lower part that penetrates into the mud to form a fertilizing groove.
1 is connected via an indicator to the pump 35 which sucks in the paste-like fertilizer through a suction hose 42 and pumps it.

[0011] Next, a description will be given of the sowing and planting. After harvesting the rice in the previous year, plowing with a rotary tilling device attached to a tractor in the autumn, or plowing in the next year if the work is convenient. I do. This eliminates the crawler marks and other irregularities of the combine at the time of harvesting, and the straw that has been shredded and spread by the cutter at the time of harvesting is thrown in together with the weeds. Then, when the soil is absorbed and becomes soft and soft by allowing the cultivated field to be flooded at the time of planting and allowing it to pass for two to three days, a simultaneous scratching planting machine is introduced into the field, and planting is performed. When the attachment device 8 and the substitute rotor 21 are driven and driven to travel, the substitute rotor 21 advances in a state of shallow penetration into the soil while rotating, and at this time, each of the ridges 22. The mud is pushed diagonally to one side with the slope going to one side, and the following slope going to the other side pushes the mud diagonally to the other side,
Since such reverse lateral extrusion is repeated, the surface layer portion of the softened soil is crushed and crushed, and the cultivated soil is kneaded well within a shallow range and properly tackified and replaced. At the same time, weeds, straw, old plants, etc. are pushed into the mud and the soil surface is leveled. The cash掻幅is the disc (blocking member) of the two side portions for receiving the mud shall be the as extruded to the side 21a, is divided by 21a, the extent to which Dai掻unit content is less wrap in the next step. Also,
Layers deeper than the scraped portion remain in the plowed state.

Immediately after such substitution, the planting device 8
Of the seedling 14 in the seedling mounting table 15 is scraped one plant at a time and planted in the scraped portion, on the side of which the rotating disc 39 forms a fertilizing groove, A nozzle 40 fertilizes the soil with the pasty fertilizer pumped by the pump 35 into the fertilizing groove. The fertilizer is not limited to the paste fertilizer, but may be a granular fertilizer. Weeds, old plants, straw, etc. are pushed into the mud during the above-mentioned shallow rubbing, and the rubbed surface soil has appropriate stickiness. And the growth of weeds can be suppressed, and the layer below the shallow soybean layer is plowed and has a large number of small voids, so the supply of oxygen to the roots and the elongation of the roots are good. The growth of seedlings is encouraged. In addition, substitute scratch rotor 2
Reference numeral 1 denotes reverse rotation (the lower surface rotates forward) or normal rotation.

[0013]

According to the present invention, omitting the Harrow process by a tractor or the like was essential to the conventional cash掻時, while Push the surface Dai掻one step weeds, the veteran or the like during mud, Harrow soil surface portion Since the soil can be muddy and leveled, and the planting work is performed at the same time as the surface layer scraping, the work efficiency can be further enhanced. By planting the seedlings on the muddy surface layer, the standing and holding of the seedlings is stabilized, so that the seedlings do not become floating seedlings or lack of stock as in the non-tilling planting method, The leveling also makes the planting depth of the seedlings uniform.
In addition, the rotor is about to be pushed to the side by the rotor.
Mud is blocked at both ends of the substitute rotor.
Planted adjacent to the side as it is received by the body
It will not push down the seedlings. In addition, the deeper layer than the scratched surface remains in the plowed state, so there are many voids, the oxygen inhalation into the soil is good, and the growth of seedlings is good. Weeding is controlled by scraping. Furthermore, the simultaneous scraping and planting machine for performing the above-mentioned scraping and planting can be achieved by a very simple device in which the conventional rice transplanter is slightly improved, and has an advantage that it can be provided at a low cost.
