Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for growing soybeans in a field.
[0002]
[Prior Art and Problems to be Solved by the Invention]
Recently, in soybeans cultivated in the field, the soybean seeds are harvested by, for example, threshing the soybeans while cutting the fields from the field by using a self-propelled self-removing combine described in Patent Document 1. It is carried out by a combine method in which only soybean seeds are sieved and harvested.
[0003]
At the time of harvesting soybean seeds by this combine, in order to ensure that the harvesting can be performed at a high yield and reliably, during soybean cultivation, in order to reduce the dropout of the soybean seeds, from the ground to the beans. It is necessary to increase the height of the soybeans and to ensure that the soybeans do not fall over the ground in order to allow reliable cutting. Furthermore, in order to make the cutting more preferable, it is necessary to make the soybeans uniform in height from the ground to the uppermost end.
[0004]
An object of the present invention is to provide a method for cultivating soybeans in such a form that preferable threshing and harvesting of soybean seeds by a combine can be easily realized.

[Means for Solving the Problems]
In order to achieve this technical object, claim 1 of the present invention provides
"When the soybeans sown and germinated in the fields or seedlings in the fields grow to the stage before flower buds grow or grow to the time of flowering, the top end of the stem in this soybean is pruned. . "
It is characterized by:
[0007]
Claim 2 of the present invention
"When a large number of soybeans that are sown and germinated in a field or planted in a field grow up to the time before flower bud formation, or grow to the time of flowering, the top end of the stem in each soybean Is pruned so that the height of the soybeans from the ground is the same. "
It is characterized by:
[0008]
Furthermore, claim 3 of the present invention
"In the above-mentioned claim 2, pruning of a large number of soybeans is performed by a clipper-type cutting blade mechanism supported so as to extend in a horizontal direction on a wheel that touches the ground."
It is characterized by:
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
When soybeans are sown and germinated or planted in a field, the soybean grows up to the time before flower bud formation in the soybean, or when it grows up to the time of flowering, the uppermost end of the stem in the soybean Pruning greatly enhances the growth of the stalk in soybeans compared to not pruning the tip in the soybean.
[0010]
Due to the significant growth of the stem, the main stem of the portion of the stem that is planted from the ground grows thicker and longer.
[0011]
Due to such growth of the main stem, when the soybean is grown to a state where soybean seeds can be harvested, the height from the ground to the legumes is greatly increased, while the main stem becomes thicker, so that it is difficult to fall down Therefore, falling down due to wind or the like can be greatly reduced.
[0012]
On the other hand, the above-mentioned pruning grows up to the time before flower buds are formed, or is performed at the time of growing up to the time of flowering, so that pruning can be formed by this pruning and the number of flower buds increases, There is no reduction in the fruit set in soybeans due to the pruning.
[0013]
Next, FIG. 1 and FIG. 2 show a traveling pruning machine 1 used for simultaneously pruning a large number of soybeans in a field.
[0014]
The traveling pruner 1 is configured as follows.
[0015]
That is, a pair of right and left support frames 2 each having a large-diameter front wheel 3 and a small-diameter rear wheel 4 at the lower end are disposed. The horizontal frame 5 is provided with a clipper-type cutting blade mechanism 6 extending in the horizontal direction on the lower surface of the horizontal frame 5, while the blower fan 7, the blower fan 7, and the cutting blade are provided on the upper surface of the horizontal frame 5. The engine 8 for driving the blade mechanism 6 is mounted.
[0016]
The traveling type pruner 1 travels forward in the direction of arrow A while holding and pushing a handle 9 extending obliquely upward from the horizontal frame 5 in this direction. In this state, the clipper-type cutting blade mechanism 6 is By driving the engine 8, the uppermost end of the stem of each of the many soybeans B growing in the field can be pruned so that the height H of the soybeans B from the ground C is substantially constant. .
[0017]
By this pruning, a large number of soybeans B grow so that the plant height from the ground C to the top end is substantially the same.
[0018]
The traveling type pruning machine 1 is configured so that the horizontal frame 5 can be moved up and down by turning a screw shaft 10 provided on each of the two support frames 2 with a handle 11 so that the cutting height H can be increased or decreased. It is configured.
[0019]
The tread T between the left and right wheels slides a bracket rod 12 projecting from one of the support frames 2 (a support frame located on the left side in the forward direction of the pair of left and right support frames) with respect to the horizontal frame 4. It is configured such that it can be adjusted up and down by movably inserting it.
[0020]
Furthermore, the stems or leaves cut by the clipper-type cutting blade mechanism 6 generate the wind generated by the blower fan 7 driven by the engine 8 through the duct 13 and the plurality of nozzles 14. It is configured such that it is blown off by this wind by spouting onto the upper surface side of the clipper-type cutting blade mechanism 6.
[0021]
【The invention's effect】
As described above, according to the present invention, when soybeans sown and germinated by seedling in a field or seedlings cultivated in the field grow up to the time before flower bud formation, or when they grow up to the time of flowering, the stem in this soybean By pruning the top end of the soybeans, soybeans can be cultivated in such a form that preferable threshing and harvesting of soybean seeds by a combine can be easily realized without reducing the yield of soybean seeds.
[0022]
Also, by pruning the top end of the stem of each of the many soybeans so that the height of the ground from the ground in each of the soybeans is uniform, the height of the top of the many soybeans from the ground to the top is almost the same. As a result, the seeds can be cultivated in such a manner that preferable threshing and harvesting of soybean seeds by the combine can be more easily realized.
[0023]
Furthermore, as described above, the pruning of a large number of soybeans is performed by a clipper-type cutting blade mechanism supported so as to extend in the horizontal direction on a wheel that touches the ground, thereby greatly improving the workability of the pruning. There are advantages that can be improved.
