Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graft success / failure determination device for grafting seedlings of different varieties to a seedling being raised and determining whether or not the grafting process is successful.

[0002]

2. Description of the Related Art When a seedling planted in a nursery pot or the like is grafted with a scion of another variety, when the grafting work is successful, water is absorbed from the rootstock side to the scion side and grows. The stem diameter of the rootstock and that of the scion are expanded according to the above, but conventionally, it was determined by visual inspection by the operator whether or not the joints were adhered.

[0003]

However, when a rootstock of a seedling is grafted with a scion, when the joint is in a bonded state, that is, when the grafting is successful, the stem diameter of the rootstock side and the scion side The stem diameter is enlarged and contracted repeatedly, and the stem diameter is sequentially expanded.

This is because the diameter of stems of the seedlings increased during the daytime and showed the maximum diameter after noon, and in the evening, water absorption from the roots did not catch up with active transpiration from the leaves and the water content in the plants was too low. This is because the stem diameter shrinks and the seedling grows at night with a constant or slight increase.

Therefore, when it is determined by visual inspection by the operator whether or not the grafting work is successful, after the grafting work,
Only after a considerable period of time had passed, the judgment could not be made, and the work could not be performed efficiently.

Further, since the success or failure of the grafting work is determined by visual observation, the measurement cannot be performed accurately and the productivity is lowered.

[0007]

Therefore, according to the present invention, the diameter of the stem on the rootstock side of the seedling that has undergone the grafting process and the diameter of the stem of the scion are enlarged.
It is intended to provide a success / failure determination device for a graft, which is provided with a measuring device capable of measuring a change in contraction and a control device for comparing the measurement results to determine the success / failure of the graft.

EXAMPLE An example of the present invention will be described in detail with reference to the drawings. In FIGS. 1, 2 and 3, reference numeral 1 is a rootstock of a seedling A being grown, and a stem portion of the rootstock 1. 2 is cut obliquely and the stem portion 4 of the scion 3 is grafted to the rootstock 1. 2-1 is a cutting portion of the stem portion 2 on the side of the rootstock 1, 4-1 is a cutting portion of the stem portion 4 on the side of the scion 3, and both cutting portions 2-1, 4-1 are in contact with each other. The outer peripheral portion of the stem is wrapped with tape 5 and held integrally.

Reference numeral 6 is a seedling raising pot for growing the rootstock 1, which is made of paper or synthetic resin and has a root portion 8 of the rootstock 1 in the soil 7 inside.
Are planted.

Reference numeral 9 is a moving means for placing the seedling raising pot 8 and moving it intermittently in sequence, and comprises a support base 10 and a rotating roller 11.

Reference numeral 12 is a measuring device having a semiconductor laser type sensor for measuring the stem diameters of the stem portion 2 of the rootstock 1 and the stem portion 4 of the scion 3, and two light emitting side stem diameter measuring sensors 12- It is composed of 1,12-2 and two light receiving side stem diameter measuring sensors 12-3,12-4. Further, the measuring device 12 can be intermittently measured while being provided on the moving path of the moving means 9.

Reference numeral 14 is a control device for comparing and processing the measured values of the stem diameter by the measuring device 12. Then, the measuring device 12
While configuring the graft success / failure determination device 13 with the control device 14 and the like, the rootstock 1 and the stems 2 and 4 of the spikelets 3 of the seedling-growing pot 6 that move in an intermittent manner are measured. The measurement is performed when the grafting is performed, the result is stored, and the measurement is performed after a predetermined time has passed in the second step.

In this case, the measured value D2 of the second stage is larger than the measured value D1 of the stem diameter on the side of the rootstock 1 on the first stage, and the stem on the side of the scion 3 is large. When the measured value D5 of the second stage is a value D6 which is larger than a certain value with respect to the measured value D4 of the diameter, it is judged that the grafting has succeeded.

On the contrary, the measured values D1 and D of the first stage
If the measured value of the second stage is smaller than 3, the grafting is judged to be unsuccessful.

In the figure, reference numeral 15 is a sorting means that operates at the time of the second-stage measurement, and the sorting means 15 selects a seedling-raising pot 6A whose grafting is unsuccessful in cooperation with the control device 14 out of the row. Is configured.

Numeral 15-1 is a hydraulic cylinder for taking out the seedling raising pot 6A from which the grafting has been unsuccessful, and 15-2 is a mounting table for placing the seedling raising pot 6A which has been taken out of the line. Reference numeral 15-3 is a solenoid valve connected to the control device 14, and 15-4 is a hydraulic pump.

Reference numeral 16 denotes a drive unit for driving the rotating roller 11, 16-1

Further, in FIG. 4, 20 is a rootstock 2 and a scion 3.
Is a graft clip for integrally holding and holding a notch portion 22 in a cylindrical holding portion 21, and bifurcated knob portions 23, 23 are provided on the opposite side of the notch portion 22 to extend the knob portion. 23,23
The notch 22 is elastically opened by pressing. Further, since the graft clip 20 is integrally formed of soft synthetic resin, the cost is low.

Further, the grafting clip 20 can be easily manufactured by integrally forming it in a longitudinal shape and cutting and separating it into an appropriate width, and the grafting work can be automated. Further, the same graft clip may be made of a shape memory alloy.

Further, as a means for measuring the shrinkage / enlargement of the rootstock and the scion, it may be possible to judge the success or failure of the grafting by causing the tape to discolor to cause discoloration.

As a method of judging the success or failure of the grafting, the water poured into the nursery pot side is colored distinctively,
It may be determined whether or not it has been sucked up by the ear.

FIG. 6 is a graph showing the variation of the stem diameter of the seedlings during the growth. It slightly increases in the relatively stable state from the evening to about 8 am, but the amount of solar radiation increases during the day. The diameter of the stem is enlarged and becomes the maximum diameter before noon.

Then, in the evening, transpiration from the leaves is activated, water absorption from the roots cannot catch up with transpiration, and the water content in the plant becomes too small, causing the stem diameter to temporarily contract.

Therefore, if the grafting is successful, enlargement and contraction of the stem diameter of the rootstock and the scion are repeated in synchronization, whereas if the grafting is unsuccessful, the stem diameter of the scion side is increased. Is one that contracts continuously.

The embodiment of the present invention is constructed as described above. Therefore, the rootstock 1 is planted in the seedling-growing pot 6 and grown for a certain period. Then, when grafting is performed on the rootstock 1, the stem portion 2 is cut obliquely. Next, the stem 4 on the side of the spike 3
Is obliquely cut, and the tape 5 is wrapped around the outer periphery while adhering the two cut portions 2-1 and 4-1, and the grafting is completed.

Next, the seedling pot 6 in the state where the grafting is completed is placed on the moving means 9 and sequentially moved, and at the same time, the stem diameter of the stem portion 2 of the rootstock 1 and the stem of the grafted scion 3 are simultaneously moved. The stem diameter of the part 4 is measured by the measuring device 12 and stored.

After a certain period of time, the seedling raising pot 6 is again placed on the moving means 9 and is intermittently moved.

Then, the stem portion 2 of the rootstock 1 is measured by the measuring device 12.
And the stem diameter of the stem portion 4 of the spike 3 is measured, and the stem diameters of both are synchronized and repeatedly enlarged and shrunk to make it larger than the previous measurement, that is, the grafting process succeeded. Existing seedling pots and seedling pots whose stem diameter is smaller than at the previous measurement, that is, those for which grafting work is unsuccessful are selected, and this result is output to the selection means 15 for unsuccessful grafting. Nursery pot 6A
To select out of line.

As described above, according to the above-mentioned embodiment, the measuring results are compared with the measuring device 12 capable of measuring the change in the expansion / contraction of the stem diameter of the graft stock 1 and the stem diameter of the scion 3. Since it is the graft success / failure determination device 13 provided with the control device 14, it is possible to make an early judgment of the success / failure of the graft, and if the grafting work is unsuccessful, it is possible to start growing seedlings again at an early stage. is there.

Further, since the change in the stem diameter of the scion 3 for grafting can be measured directly or indirectly, the measurement work can be performed accurately, and therefore the work can be carried out efficiently while the overall structure is simple. Is what you can do.

In the above-mentioned embodiment, the grafted seedling A is placed on the moving means 9 which moves intermittently, and the change in stem diameter of the seedling A on the rootstock side and the scion side is automatically measured. Since the measurement result is accurate, the yield of grafted seedlings is greatly improved.
