Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fertilization method and fertilization device for fertilizing simultaneously with rice planting work.

[Prior art]

As a conventional technology of this kind, Utility Model Application No. 57-82111
As shown in the publication, there is a fertilization device that applies fertilizer at the same time as planting seedlings at a shallow position near and to the side of the shoots that are planted by the seedling planting device.

[Problem to be solved by the invention]

In the conventional example, the planted seedlings grow smoothly due to the effect of fertilization in the early stage after planting, but as the seedlings grow, the effect of fertilization disappears, and additional fertilization is required. .

[Means to resolve the problem]

In order to solve the above-mentioned problem, the first invention is to simultaneously plant seedlings in a shallow position near and to the side of the shoots A to be planted by the seedling planting device 4 and at a deep position in the middle between the shoots. The second invention is a fertilization method for applying fertilizer, and the second invention is a method for applying fertilizer to a fertilizer application pipe 10',
A lateral fertilization device that applies fertilizer into a shallow groove a formed by a groove cutting body 14 on the side near the seedling A to be planted by the seedling planting device 4 guided by the seedling planting device 4 and a fertilizer hopper 9. A fertilization device comprising a deep fertilization device that guides the fertilizer delivered from the fertilization pipe 10 through a fertilization pipe 10 and applies fertilizer to a deep position b in the middle between the seedlings A and 4, which are planted in the seedling planting device 4. It is.

[Operation and effect of the invention]

The present invention provides a fertilization method and a fertilization device for fertilizing at the same time as planting seedlings at a shallow position on the side near the seedlings I planted by the seedling planting device 4 and at a deep position in the middle between the shoots. Seedlings planted with fertilizer near and to the side of the shoots grow smoothly after planting, and when the seedlings grow and their roots extend deep to the depths between the shoots, they grow in the middle part between the shoots. Continue to grow smoothly by fertilizing at deep locations. Therefore, by performing shallow side row fertilization and deep fertilization at optimal positions simultaneously with rice transplanting, work efficiency can be significantly improved.

〔Example〕

Hereinafter, one embodiment of the present invention will be specifically described based on the drawings.

First, we will discuss its configuration.

The vehicle body 1 is equipped with an engine 2 at the front, and a seedling planting device 5 consisting of a seedling tank 3 and a seedling planting device 4 at the rear.
It is equipped with a float 6 attached to the bottom.

7 indicates a handle.

The wheels 8 are mounted on shafts at the intermediate portion of the vehicle body 1, and are driven by rotational power from the engine 2, so that the vehicle body 1 can be propelled.

The fertilizer hopper 9 is attached to the vehicle body 1 above the wheels 8, and has several fertilizer pipes 10, 10', 10'' attached thereto so as to be able to store fertilizer.

The fertilizing pipe 10 is provided with its fertilizing port 11 located at the front side in the forward direction of the wheels 8 and opened. In addition, other fertilization pipes 10', 1
0'' is provided at the rear of the vehicle body 1 by opening near the seedling planting device 4.The fertilizer hopper 9, its delivery portion, the fertilizer pipe 10, and the wheels 8 constitute a deep fertilization device, 9, its delivery portion, fertilization pipes 10', 10'', and the working body 14 constitute a side-row fertilization device.

In addition, 12 shows an auxiliary seedling tank, and 13 shows an auxiliary float.

Next, its effect will be explained.

First, fertilizer is supplied to the fertilizer hopper 9, seedlings are placed in the seedling tank 3, and work is started.

The rotating parts of the vehicle body 1 are driven by rotational power from an engine 2, and the seedling planting device 4 plants seedlings in a field while moving forward by wheels 8.

During such work, the fertilizer sent from the fertilizer hopper 9 to each of the fertilization pipes 10, 10', 10'' is dropped onto the field from the fertilization port 11 thereof.

Then, the fertilizer dropped to the front side of the wheel 8 through the fertilization pipe 10 is stepped into the field by the rotating wheel 8, and as the rotation progresses, it is pushed down deeper and the fertilizer is applied to the deep layer of the field.

On the other hand, the fertilizer falling from the fertilization pipes 10' and 10'' is applied to the shallow layer of the field.

To illustrate this relationship, as shown in FIG. 2, fertilizer is applied to the shallow layer and deep layer of the field, respectively.

Generally, in the above-mentioned fertilization work, a fast-acting fertilizer is applied to the shallow layer of the field, and a slow-acting fertilizer is applied to the deep layer, so that the two work together to maintain a relatively long fertilizing period.

Therefore, by applying fast-acting fertilizer in a shallow position near and to the sides of the seedlings to be planted in the field using the seedling planting device 5, the planted seedlings can grow smoothly after being planted. By applying a slow-release fertilizer deep in the middle between the shoots, the effect of the quick-release fertilizer described above is about to wear off (when the seedlings have grown and their roots have grown deep between the shoots). When the slow-release fertilizer takes effect, the seedlings continue to grow smoothly. Therefore, even if you do not perform additional fertilization after planting seedlings with a rice transplanter (for farmers who fertilize multiple times after rice planting, the number of times of additional fertilization can be reduced), the seedlings will grow smoothly, making the work much more effective. can be improved.

In addition, the wheels may be driving wheels or driven wheels,
In short, any device that tramples the fertilizer that has fallen on the front side as it rotates and pushes it into the deep layer will suffice. Furthermore, if the wheels are configured in the shape shown in FIG. 3, the stepping action will be larger and more effective.
