Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application) The present invention relates to a method for transplanting seedlings and an apparatus therefor, and more particularly to a method for growing and transplanting a large number of seedlings and an apparatus used therefor.

(Prior Art) Conventionally, when growing seedlings in a wide seedbed and directly burying them, the roots of adjacent seedlings are planted at certain intervals so that they do not affect each other. Next, when the need for transplantation arises during the growing process of seedlings (for reasons such as growing the seedlings to a certain quality and strength), the seedlings are dug up each time and transported to the transplanting location without damaging the seedlings. Burial implantation is being carried out. In addition, for the purpose of intensively managing seedlings on small plots of land, immature plants planted in small plastic sheet pots are densely laid out in seedbeds for intensive management.
When it becomes necessary to transplant the seedlings as they grow, the seedlings can be directly buried in another large nursery at a distance that will not hinder the growth of the seedlings, or the grown adult trees can be dug up to make it easier to grow them on the ground. Methods such as burying the plant in the soil via a transplant packaging bag have been implemented.

However, this method requires not only a space for transplanting the seedlings but also a work space for the transplanter to grow a large number of seedlings. The drawback is that it requires a great deal of labor and time to load soil, supply water, etc., which increases the cost of cultivation.

(Problems to be Solved by the Invention) An object of the present invention is to provide an effective method for transplanting and cultivating a large number of seedlings, which eliminates the drawbacks of the prior art as described above, and an apparatus for use in the method.

(Means for Solving Problems) The seedling transplanting method of the present invention involves arranging a plurality of seedling pots, planting seedlings in the pots in advance, supplying soil from above with a soil supply device, and then It consists of showering water over the pot.

Furthermore, the seedling transplanting device of the present invention for use in the method of the present invention includes a chute with a vibrator for supplying soil by gently dropping from the top of the transplanted seedling approximately in the center of the pot, and a metering device for supplying the required amount of soil. The pot is equipped with a hopper and a water supply means for allowing the soil to flow throughout the pot.

The method of the present invention is generally used for the purpose of mass production and centralized management when seedlings planted in small vinyl sheet pots and grown in a dense nursery are transplanted during the growing process.

The pots for seedlings used in the method of the present invention preferably have a strength that allows repeated use without deformation when a plurality of pots are arranged, and any material may be used as long as it has such strength.

The size and shape are also not particularly limited as long as they do not interfere with or damage neighboring mature trees when they reach a predetermined mature size and allow the necessary rooting for growth, but are usually about 20 cm in diameter, Preferably, the height is about 12 cm. A small hole for draining water is also provided at the bottom of the pot. A plurality of these pots for transplanting seedlings are sequentially arranged in rows and columns in a nursery bed such as a flat area with a predetermined section or a bed for laying seedling pots raised with earth mounds or other means. Insert mature seedlings.

Next, soil is supplied by a soil supply device as described later.

This soil has an apparent density of 0, which has been mixed and measured in advance to a predetermined ratio.
．． Light culture soil of 5 g/cnr or less is preferable, and is usually poured slowly from the top of a plurality of pots laid out in rows at the same time. Then, shower with an appropriate amount of water and evenly distribute the soil into the seedling pot. This showering of water serves to uniformly fill the soil and to supply the moisture necessary for the growth of seedlings. Next, the soil supply device is moved to the position of the potted seedlings arranged in the row adjacent to the above, and soil and water are sequentially supplied in the same manner as described above.

In this way, a large number of seedlings can be transplanted in a short time and with a minimum amount of labor by inserting seedlings into the pots arranged in large numbers in rows and columns, and then continuously supplying soil and water. Can be done.

Next, the present invention will be explained based on the drawings.

Figure 1 is a cross-sectional view of an immature seedling placed in a transplant pot, Figure 2 is a perspective view of a plurality of potted seedlings shown in Figure 1 placed in vertical and horizontal rows in a nursery bed, and Figure 3 is a cross-sectional view of an immature seedling placed in a transplant pot. FIG. 4 is a side sectional view showing the state in which the soil supply device is supplying soil and water to potted seedlings arranged in vertical rows in the nursery bed, and FIG. 4 is a front view of FIG. 3.

As shown in FIG. 2, a plurality of the above-mentioned transplanting pots 2 having small holes 4 for draining water at the bottom are arranged in columns and rows as shown in FIG. It is preferable that the bottom of the pot and the seedling bed be separated by about 2 to 3 barrels, rather than being in close contact with each other. This is to prevent root rot by draining excess rainwater during rainfall, and to slow down the drainage of excess water during transplant showering, thereby promoting the effect of increasing soil distribution and uniformity of root compaction. Transplant immature seedling 3 approximately in the center of the pot. These plants are placed and transplanted by hand, but because they are placed and transplanted sequentially from the front row on the seedbed, no work space is required for the transplanter, and transportation is carried out before the supply of soil and water, making it lightweight and easy to use. Handling work can also be carried out easily.

Next, soil and water are supplied by a soil supply device as shown in FIGS. 3 and 4. That is, a predetermined amount of soil is prepared in the soil hopper 5, and the soil is transferred from there to the weighing hopper 7 via the tonosho adjustment grid 6, where it is stirred by the bridge breaker 8 to prevent discharge clogging, and the soil is quantified depending on the rotation speed. A measuring device 9 having a function of weighing in portions measures a fixed amount, and a vibrator 10 distributes the amount and supplies it to the pot 2. Immediately after supplying the soil, water is sprinkled with a shower from the water supply port 11 to uniformly fill the soil around the seedlings and to supply water necessary for root tightening and growth. In this way, soil is poured in one operation cycle for each divided section,
When molding and water supply are completed, the device is moved to the next divided section and the same operation is repeated.

In the above, once the soil is supplied to the pot 2, a space is created above the weighing hopper 7, and as the soil pressure decreases, the soil passes through the soil pressure adjustment grid 6 and reaches the soil in the soil hopper. 7, and the amount of soil in the weighing hopper 7 is maintained at a constant amount. The soil in the weighing hopper 7 is constantly stirred by the bridge breaker 8, eliminating fluctuations in the amount of soil sent to the measuring device 9, and the amount of soil transferred from the measuring device 9 can be fixed and stable.

The amount of soil transferred from the measuring device 9 is mainly determined by the rotation angle of the rotating measuring device 9 and the positional relationship of the adjusting plate 12, but it changes depending on the particle size, mixing ratio, moisture content, etc. of the soil.

To explain more specifically the behavior of the soil transferred from the weighing Wi 9, the soil guided and transferred to the lower part by the guide cylinder 13 falls into the shooter 14 divided into the number corresponding to the number of pots in one row. The fall adjustment plate 17 stops the soil once, and the attached vibrator 10 gently and evenly disperses the soil so that it falls almost to the center of the sapling 3, and continues to fall on the branches or leaves of the sapling 3. It passes through the gap and falls in a circular shape in the center of 2 and in the vicinity of the seedling 3, and is deposited.

At this time, the vibrator 10 has the function of preventing the soil from adhering to and accumulating on the wall of the chute 14 and forming bridging when the soil passes through the chute 14, and also has the function of smoothing the fall of the soil.

With most of the desired amount of soil deposited in the pot 2 or a portion of the soil on the branches or leaves of the seedling 3,
Water is sprinkled with showers from the number of water supply ports corresponding to the number of shooters, and the soil accumulated on the branches or leaves of the seedlings 3 is washed down by the water force of the water spray, and watering is continued. The soil piled up in the shape of a suribachi mountain inside 2 is made to have a substantially flat surface while increasing its density by the water flow or flow force of watering, and the seedlings 3 are stabilized. Furthermore, excess water is drained out through several drainage holes provided at the bottom of the pot 2.

After the operation for one row thus divided, a suitable drive mechanism, such as the moving wheel drive handle 15, is rotated a predetermined number of times to move the device to a fixed position by means of the moving wheels 16, and then fixed with a stopper.

In the above example, a transplanting method was shown in which transplant pots were placed on a nursery bed, but seedlings transplanted into seedling root packaging bags of other species can also be planted by digging holes in the ground in predetermined vertical and horizontal rows. However, soil and water may be sequentially supplied in accordance with the above.

(Effects of the Invention) The method and device of the present invention make it possible to reliably and continuously fill a pot with a fixed amount of soil, reduce the production cost of seedling products, and raise seedlings of stable quality with no variation in the amount of soil filled. can produce products.

In the present invention, each seedling is planted in a pot one by one, so there is no chance that the roots of adjacent seedlings will interfere with each other.
It is possible to centrally manage and grow a large number of seedlings on a small amount of land.

By using transplanting pots that are strong enough to be used repeatedly without deforming when multiple transplants are placed, and that are shaped and sized to suit the rooting and leaf shaking required for mature trees, they can be transplanted in rows and rows on the nursery. Because the spacing can be naturally regulated and the placement stability is good, soil can be easily removed using a soil supply device.
Water supply can be completed in a short time with minimal effort. The conventional method was limited to about 200 pieces per day per person, but according to the present invention, it is possible to achieve an efficiency increase of more than 10 times to 2500 pieces per day per person.

In addition, by using a funnel-shaped pot, mature trees can be easily removed from the pot at the time of shipping without damaging the branches and leaves around the roots, and the remaining pot can be used for the next generation of immature seedlings. It can be used to grow transplants, reducing the cost of growing transplants.

As described above, the present invention has many excellent effects as a transplanting and growing system for seedlings for mass cultivation.
