Description

[0001]
BACKGROUND OF THE INVENTION
The present invention concentrates and applies fertilizers or pesticides to the root area of crops that are cultivated by raising straw, and the fertilizers or agricultural chemicals and soil are stirred so that the fertilizers or agricultural chemicals can be utilized without waste. The present invention relates to a belt stirrer.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is a well-known standing apparatus including a tilling rotary that extends in the horizontal direction and a pair of straw forming plates that are provided behind the tilling rotary and that form a pair of soil that has been cultivated by the tilling rotary. As shown in FIG. 7, when pesticides such as basic fertilizer and soil disinfectant are applied to the crop 18 that is cultivated with the ridge 19, using this ridger, the whole surface of the ground is spread before cultivating the field. Then, since it is cultivated by the rotary tillage and is set up, the agitation zone 20 of the fertilizer and the agrochemical is dispersed throughout the ridge 19.
[0003]
In such an application method, since fertilizers and pesticides to be applied are dispersed throughout the straw, only those in the rhizosphere 18a of the crop 18 are used, and fertilizers and pesticides distributed elsewhere are not used, The effect of fertilizers and pesticides is not necessarily high because they run out in the rain. This causes environmental problems such as increased application costs of fertilizers and pesticides and contamination of groundwater, rivers and lakes.
[0004]
For this reason, there is a need for a machine that increases the effects of fertilizers and pesticides and reduces the amount used by applying fertilizers and pesticides concentrated in the root zone of the crop. As a fertilizer applicator having such a purpose, various techniques for applying fertilizers locally in soil have been disclosed (see, for example, Patent Documents 1 to 8). In these prior arts, there is a problem that fertilizer is only applied locally in the soil, and initial growth is delayed in vegetable cropping.
[0005]
There is also prior art about a device that applies fertilizer to a flat ground while stirring (see, for example, Patent Documents 9 to 10). In the techniques described in these prior arts, the fertilizer is only applied to the flat ground while stirring, the stirring depth is constant, and cannot be applied to the root of the crop, that is, the crop rhizosphere. There was a problem.
In any of the above prior arts, only fertilizer is applied, and no mention is made of stirring application of agricultural chemicals such as soil fungicides.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be specifically described with reference to the accompanying drawings.
1 and 2, reference numeral 1 denotes a tilling rotary extending in the horizontal direction similar to a rotary tiller provided in a conventionally known tiller. The tilling rotary 1 is connected to a riding management machine (via a hitch unit 2). It is attached to the tractor 3 so as to be movable up and down. A rotary shaft 4 is rotatably mounted on the rotary rotary 1, and a plurality of tilling claws 5 project radially from the outer periphery of the rotary shaft 4 in a predetermined arrangement in the length direction. .
[0012]
The hitch portion 2 is provided with a transmission 6, and an input shaft projects from the transmission 6 so as to be rotatable forward. The input shaft is powered by a universal joint and a propeller shaft from the PTO shaft of the riding management machine 3. Is transmitted. The power shifted in the transmission 6 is transmitted to the rotary shaft 4 via the chain transmission system in the chain case 7, and the rotary shaft 4 is rotated in a predetermined direction to cultivate the soil in the field by the tilling claws 5.
[0013]
A connecting frame 9 is fixed to the main frame 8 of the tillage rotary 1, and a support column 10 is fixed to the connecting frame 9 downward, and the soil plowed by the tillage rotary 1 is placed on the lower end of the support column 10 behind. A saddle forming plate 11 is fixedly attached.
This saddle-molded plate 11 is composed of a pair of left and right, and in order to adjust the standing height by raising and lowering the support column 10, the connecting frame 9 and the support column 10 are fixed with bolts, etc., and the tightening is released and tightened. The structure can be changed easily.
[0014]
A hopper support 12 is erected on the left and right of the main frame 8 of the tillage rotary 1, and a hopper 13 for storing granular or powdered fertilizer or agricultural chemical is attached to the upper end of the hopper support 12. A feeding portion 14 driven by a motor is provided at a lower end portion of the hopper 13. An upper end of a hose 15 that is a discharge pipe is connected to the feeding portion 14, and the fed fertilizer and agricultural chemical fall through the hose 15 by its own weight and are guided to the spray port 16. The fertilizer and pesticide discharged from the spraying port 16 to the soil are sequentially sprinkled on the field scene as the management machine 3 moves forward.
[0015]
On the other hand, two pairs of left and right disks 17 and 17 are fixed to the rotary shaft 4 symmetrically at a predetermined interval. Between the discs 17 and 17, the spray port 16 of the hose 15 is faced, and the tilling claws 5 of the tillage rotary 1 are interposed, so that the fertilizer and agricultural chemical discharged between the discs 17 and 17 can be removed. The discs 17 and 17 are stirred with the soil. The diameter of the disk 17 is set to be slightly larger than the diameter R of the rotary outer periphery of the tilling rotary 1. The distance between the discs 17 and 17 is adjusted by moving the mounting position with respect to the rotary shaft 4 in the axial direction. For this reason, the disc 17 and the rotary shaft 4 are fixed with bolts or the like so that the distance can be easily adjusted. Yes. The pair of left and right ridge forming plates 11, 11 are disposed behind the disks 17, 17. The inner band-shaped stirring applicator of the present invention is configured as described above.
[0016]
Then, as the riding management machine 3 travels forward, the fertilizer or pesticide sprayed in a streak shape from the spray port 16 between the pair of disks 17 and 17 is stirred by the tillage claws 5 between the disks 17 and 17. Then, as shown in FIG. A ridge 19 is formed by the ridge forming plates 11, 11 adjusted to the necessary ridge width and ridge height behind the disks 17, 17. The fertilizer or pesticide agitated with the soil is laid so as to come to the center of the ridge 19 as a fertilizer / pesticidal agitation zone 20. The crop 18 is cultivated in the fertilizer / pesticidal agitation zone 20, the fertilizer is absorbed from the root zone 18a, and the agricultural chemical acts on the root zone 18a of the crop.
[0017]
When the belt-like stirrer and applicator according to the present invention was prototyped and mounted on the riding management machine 3 and fertilization or simultaneous application of the fertilizer was performed in the field, a width of 15 mm to 30 mm at an arbitrary depth in the rod 19 was obtained. It was confirmed that a fertilizer or pesticide could be applied in a belt shape and a fertilizer / pesticidal stirring zone 20 was formed, and there was almost no dispersion of fertilizer or pesticide in the soil other than the purpose (fertilizer / pesticide stirring zone 20).
[0018]
Yield (effect) when cultivating summer cropping cabbage is shown in FIG. 4 and the graph of the yield (effect) when performing fertilizer local application using the belt inner stirrer of the present invention and cultivating summer crop cabbage. ) Is shown in FIG. Furthermore, it shows in FIG. 6 the graph of the effect when pesticide (nevidin) local application is carried out using the inner strip-shaped stirring applicator of the present invention and cabbage is cultivated.
[0019]
When cabbage and Chinese cabbage were cultivated by the two fertilization methods, the conventional fertilizer application method (see FIG. 7) for applying fertilizer to the entire culvert 19 and the inner strip-shaped stirring fertilization method (see FIG. 3) according to the present invention, both fertilization methods If both were standard fertilization amounts, the yield was statistically apparently higher in the case of the cocoon strip fertilization (see FIGS. 4 and 5). In the case of agitation in the cocoon strip, even if 50% fertilizer was reduced from the standard fertilizer application amount, there was no statistical difference in yield compared to the case where the standard fertilizer application method was used.
[0020]
In addition, when cabbage was cultivated by two methods, the conventional method of applying a soil disinfectant to the entire culm 19 and the inner strip-shaped agitation method according to the present invention, the concentration of the standard specified for both methods was obtained. There was no difference in the effect on soil diseases when the amount was applied (see FIG. 6). According to the method for stirring and applying a band in a sputum according to the present invention, since the range of stirring and applying in a band is small, it was found that the amount of agricultural chemicals used in the entire field was reduced to 1/3 to 1/4. In the above-described embodiment, only one fertilizer / pesticidal stirring area 20 is formed on the ridge 19, but a plurality of fertilizer / pesticidal stirring areas 20 are formed on the heel 19. It is good.
[0021]
【The invention's effect】
As explained above, since the inner strip-shaped stirrer of the present invention has the configuration according to claims 1 to 3, a small amount of fertilizer can be effectively absorbed by the crop. Moreover, soil diseases can be suppressed with a small amount of pesticide. Thereby, the fertilizer cost or the agricultural chemical cost can be reduced, and the environmental conservation type agriculture in which the fertilizer is hardly lost and the usage amount of the agricultural chemical is suppressed can be realized.
