Are combined in a front-rear arrangement. At this time, the steel mat 32 is formed by joining a large number of metal blade pieces in a planar shape, and the whole of the steel mat 32 slides on the ground while following the ground, and acts to level the fluid soil on the ground. This includes, for example, what are called multiple blades.

Next, usage examples and operations of the apparatus according to the present invention configured as described above will be described.
The height of the vertical rotary disk 8 with respect to the grooving claw 11 is adjusted to the optimum state, and the height of the gauge ring 13 with respect to the grooving claw 11 is adjusted to the optimum state. Further, for example, about 70 kg to 80 kg of organic soil y is accommodated in the container 14.

  About the content of organic soil y, it will be effective mainly by garbage compost and sludge compost by investigating the local soil. Mix organic and non-organic components that can be transformed. For example, if the amount of fertilizer is low, fertilizer such as chicken manure or cow manure compost, conversely if excessive fertilizer is used, use zeolite or a porous improver, etc., especially if caking is a problem, rubber chips, etc. In case of poor drainage, mix drainage material such as coarse sand.

The organic soil y used here includes pellets, granules, powders, sands, or composts, but does not include liquids or pastes.
Further, the organic soil y is preferably composed mainly of garbage compost or sludge compost containing actinomycetes that antagonize the pathogenic fungi (filamentous fungi) of the lawn. It is strengthened and the disease prevention effect by actinomycetes is improved.

  After this state, the operator gets on the tractor T, lowers the entire device, grounds the gauge wheel 13, and moves forward at about the walking speed to operate each part. While the entire apparatus is moving forward, first, a number of longitudinally rotating discs 8 are transmitted from the engine of the tractor T and rotated forward (rotation in the arrow direction f2) to deepen the lawn without disturbing the surroundings. It cuts smoothly and continuously in about 2 cm to 3 cm. As a result, the total thickness of the rhizome layer s1 of the lawn g shown in FIG.

  Immediately behind each longitudinally rotating disk 8, the groove claw 11 is moved forward by the tractor T while transmitting the rotation of the engine and rotating backward (rotation in the direction of the arrow f 1). A plurality of grooves k1 having a depth of about 5 cm to 15 cm and a width of about 10 mm to 25 mm are formed by excavating k cutting lines of the cutting rotary disk 8 without causing excessive damage to the rhizome layer s1, and a groove pitch in the left-right direction. It is formed continuously so that p is about 10 cm to 25 cm. At this time, the power required for the rotation of the groove claw 11 is relatively small due to the presence of the cutting line k. After the groove k1 is formed in this way, the groove k1 extends over almost the entire range of the depth of the irregular root n of the turf, and the soil g1 dug up during the formation of the groove k1 rises to the left and right portions of the opening of the groove k1. It will be in a state that exists.

  In addition, at a position that is directly behind each longitudinally cut rotary disk 8 on the rear side of the groove cutting claw 11, the lowermost part of the two soil guide rotating disks 22 and 22 corresponding to the part is the opening of the groove k1 corresponding thereto. So that the soil guide rotating disks 22 and 22 are moved forward by the tractor T so as to be rotated by applying a rotational force by friction with the ground g so as to follow the opening of the groove k1. Moved. On the other hand, the feeding roll 20 is rotated at a constant speed appropriately adjusted in a specific direction by the DC motor 21, and the organic soil in the container 14 is passed through the nutrient soil pumping groove d at a suitable constant flow rate through the hole c <b> 1. The organic soil y that has been fed out in this way passes through the drop guide tube 16 to the upper portion of the inclined guide plate 23 in the front half range of the corresponding portion between the two soil guide rotation discs 22 and 22. It is dropped and then moved to the lowermost part between the two soil guide rotating disks 22 and 22. At this time, the rotation of the two soil cultivation guide rotating disks 22 and 22 promotes the downward movement of the organic soil cultivation y, and the inclined guide plate 23 moves the organic farming forward of the two soil cultivation guide rotating disks 22 and 22. The soil y is prevented from scattering and is caused to flow downward by the gravitational action toward the lowermost part of the two soil culture guide rotating disks 22 and 22. In this way, most of the organic soil y that has reached the lowermost part of the location between the two soil guide rotating disks 22 and 22 falls into the groove k1 due to gravity.

  Within the rear half of the location between the two soil guide rotation discs 22 and 22, the corresponding soil suppression and rotation disc 27 is identified by the support force by the ground contact of the two soil guide rotation discs 22 and 22. The two soils are supported while being pressed at the upper surface of the organic soil y that has fallen into the groove k1 while being supported at a height and the lowermost part is fitted in the corresponding groove k1. It is moved forward by the tractor T in the same shape as the guide rotating disks 22, 22, and during this movement, a rotational force is applied by contact resistance with the ground g and the organic soil cultivating y, and it is rotated. The rotation of the soil suppression pressure rotating disk 27 contributes to the movement of the organic soil y in the lower part of the location between the two soil guiding rotation disks 22 and 22 into the groove k1. Thus, the soil supply unit 3 is moved forward by the tractor T while supplying the organic soil y in the container 14 to each groove k1 at a specific flow rate, and the corresponding soil-containing pressure reducing rotary disk 27 supplies the organic matter in each groove k1. The upper surface of the soil culture y is continuously compressed so as to have a specific depth (for example, about 1 cm to 3 cm).

  The steel mat 32 is moved forward by the tractor T while following the ground g on the rear side of the soil-crushing rotary disk 27. During the forward movement, the steel mat 32 is dug up by the grooving claws 11 and is shown in FIG. As shown in FIG. 7, the soil g1 that is raised on the ground g is spread with a large number of blade pieces to a thickness of about 2 mm to 5 mm to form a grass soil, and the organic matter in the groove k1 as shown in FIG. It will be in the state which covered the soil y and the ground g.

  In the above embodiment, the vertical cutting disk 8 and the supporting mechanism and driving mechanism related thereto can be omitted, and when this is omitted, there is damage to the grass in the groove forming process by the groove cutting claw 11. As the power increases, the required power tends to increase, but the work is not impossible.

  Further, the spread leveling means 28 may be omitted. In this case, after the organic soil is supplied to the lawn, only the leveling process of the soil g1 as the joint soil is performed separately. When the moisture of the soil is excessive when the groove k1 is formed, it may be better to separately perform the leveling treatment after the soil is sufficiently dried.

The turf applied with about 500 g of dry chicken manure per 1 m ² as a soil by the implementation of the method of the present invention has a noticeable green color on a shorter day (about 1 week) compared to the turf that was not applied. Even if fertilizer application was omitted, it grew vigorously.

  In late-May and mid-September, 500g of sludge compost per square meter was applied as a soil for observation on a lawn habitat where leaf rot (Rhizoctonia large patch) occurs. However, in spring and autumn, no outbreak was found, and in places where it was not applied, normal occurrence was seen.
