Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for cultivating cracked radish. This is used in the field of cultivation, where seeds of vegetables and the like are germinated and harvested at the stage of young plants.

[Prior art]

A variety of vegetables are available on the market, but in recent years, daikon radish is often found packed or in containers, as it is prized for its flavor. This radish is shipped to the market after the radish has grown to a height of, for example, about 12 cm.

Conventional methods for cultivating daikon radish include directly sowing seeds in seedbeds in fields and growing them, growing them in flat seedling boxes filled with soil, and growing them in small seedling pots. be. However, in order to increase production in response to the growth in demand for daikon radish, large areas of land and space are required, making it difficult to increase production.

In order to solve this problem, improvements were made to the cultivation method, and a cultivation method was developed that improved the productivity of cracked daikon radish, increased the product value, and made a group of young plants into one unit that was easy for consumers to use. has been done. As an example,
There is a plant cultivation method and apparatus described in Japanese Patent No. 15086. In cultivating daikon radish using this method, the seeds are soaked in water for about a day to absorb water, sown at the cultivation base of a seedling nursery box, and then grown in a dark room. Water and liquid fertilizer are added to the base of the plant to the extent that the sown seeds are lightly submerged, so the seeds will germinate the next day. When grown in a light-shielded room while supplementing the base with liquid fertilizer as the radish germinates, the daikon radish will be ready to be shipped in about 5 to 6 days. If the young plants in the seedling box are left in sunlight for just one day before shipping, the leaves at the tips will turn a fresh green color. This method is
Since it can be grown without using soil and bundles can be stored and shipped in containers, it is possible to increase the productivity and commercial value of daikon radish.

However, in the above-mentioned cultivation method, the daikon radish delivered to the market has the disadvantage that it has a relatively short shelf life because it is exposed to sunlight for only one day before shipping without exposing it to light until the day before shipping. In other words, after being shipped, daikon radish continues to grow to some extent when it is exposed to sunlight or lighting inside a retail store or store, but its shelf life is poor throughout the seasons, and it wilts and rots quickly, especially in the summer, and sellers We hear dissatisfaction from customers and consumers, and the amount of waste increases.

[Purpose of the invention]

The present invention has been made to solve the above-mentioned drawbacks, and its purpose is to provide sellers and consumers with a cultivation method that can supply long-lasting cracked radish throughout the year.

[Structure of the invention]

The characteristics of the method for cultivating daikon radish of the present invention will be explained with reference to FIG. 1. The steps include a step of absorbing water from radish seeds in a soaking tank 3 and a germination chamber 4, and after sowing the seeds in a seedling box 5. The process of germination in the light-shielded seedling nursery room 2 (2A, 2B) and the lighted shelf room 9 for seedlings about two days after sowing.
The method includes the step of cultivating the plants under indirect and direct sunlight until the date of shipment.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of a device suitable for carrying out the present invention will be described in detail below based on the drawings.

As shown in Figure 1, the cultivation room 1 for daikon radish is a large greenhouse. Its structure consists of each part of the building steel frame,
An aluminum sash inlaid with transparent glass is installed,
It allows sunlight and heat to enter. Further, the ceiling is provided with a plurality of automatically opened and closed skylights for adjusting the temperature of the cultivation room 1. Inside the cultivation room 1, seedling growing rooms 2A and 2B with a light-shielding structure are installed, and in the seedling growing room 2B, there is a dipping tank 3 for allowing the seeds of radish to absorb water.
A germination chamber 4 is provided for promoting germination of seeds soaked and absorbing water. In this example, seeds are sown every day and the seedling growing boxes 5 are stored in the seedling growing room 2 for two days with watering in between, so in order to clarify the classification, there are two seedling growing rooms 2A.

It is divided into 2B.

A conveyor 6 is installed in front of the seedling nursery room 2, and a seeding machine 7 and a watering machine 8 are installed on the conveyor 6, and both can sow seeds in the seedling nursery boxes 5 and water them after sowing. . The seedling raising box 5 described above is, for example, a rectangular box made of expanded polystyrene resin, and when a partition plate is inserted, for example, 20
Divided into separate sections. Each compartment is designed to grow a group of daikon radish, which will be shipped as a unit, and the bottom of each compartment has multiple shallow holes to store the liquid fertilizer needed to grow the seeds after sowing into young seedlings. A long groove is provided. In other words, care has been taken to enable cultivation using only liquid fertilizer without using soil, and to ensure that clean daikon radish can be shipped.

The shelf room 9 includes a plurality of rows, for example, six rows of seedling raising shelves 10A.

10B are installed to sandwich the roller conveyor IIA, and the seedling raising shelves 10 in each row are divided into, for example, four upper and lower stages, back to back. A seedling growing box 5 containing young seedlings immediately after germination is placed on each shelf, and the seedlings are exposed to direct or indirect sunlight until they are shipped.

A roller conveyor LLB for conveying the seedling growing boxes 5 is installed between the seedling growing room 2B and the shelf room 9, and is connected to the above-mentioned conveyor IIA at a bend. In addition, conveyor I
Each of the unit conveyors constituting the IB is fixed to the floor and connected to each other by connecting members. On the other hand, conveyor I
In the IA, each of the unit conveyors has a caster at the bottom and is connected to each other by a releasable connecting member. Therefore, when an operator carries out the seedling raising box 5 or sprinkles water, the worker can move freely between the seedling raising shelf 10A and the IOB by disconnecting the connecting part of the conveyor IIA and shifting one conveyor row. .

In parallel with the above-mentioned conveyor IIB, a shipping roller conveyor 12 is provided with a downward slope toward the backing workbench 13. Its structure is the same fixed type as conveyor 11B, and can send seedling boxes 5 from conveyor 11A to backing workbench 13.

In the cultivation room having such a configuration, the method for cultivating daikon radish of the present invention is carried out as follows.

Figure 2 is a time schedule showing the cultivation process of daikon radish. Prior to soaking, weigh the seeds that will be shipped on the 6th day after sowing based on the production plan, place that amount of seeds in perforated cloth or mesh bags that can be easily drained, and divide them into, for example, about 3 kg. . The seeds are soaked together with the bag in water at a temperature of 25° C. in the soaking tank 3 shown in FIG. 1 for about 7 hours, during which time the seeds absorb water and become swollen.

After the worker hangs the bag, drains it, and places it in a basket,
The bag is placed in a dark germination chamber 4 for 15 to 20 hours until the next morning, and the seeds are kept in a state where they are easy to germinate in the chamber whose temperature is adjusted to around 30°C.

Subsequently, the seeds taken out from the bag are put into the hopper of the seeding machine 7 shown in FIG. 1, and the empty seedling growing boxes 5 are sequentially placed on the conveyor 6. The seedling raising box 5 is conveyed under the seeding machine 7 by a belt, and approximately the same amount of seeds are sown in each section while passing under the seeding drum. Next, the seedling raising box 5 is conveyed under the watering machine 8, and the liquid fertilizer is evenly sprayed by the watering nozzle of the watering machine 8. The seedlings are stored in a light-shielded nursery room 2A at a room temperature of 25° C. in a stacked state of about 10 to 15 layers for 20 to 24 hours, and germinated. Before the next day's sowing and watering according to the schedule, the seedling boxes 5 of the two seedling rooms are placed on the conveyor 6.
The seedlings are placed on the seedlings, and are again sprinkled with water using the water sprinkler 8, and kept in the seedling growing room 2B at a room temperature of 25° C. for 5 to 6 hours. As described above, the seeds taken out from the germination chamber 4 are grown into seedlings of about 2 cg+ in light-shielded conditions over a period of about two days.

In order to grow the seedlings into young vegetables with a height of approximately 12 cm that can be shipped as split radish, the seedling raising box 5 is transported by a conveyor IIB to a well-lighted shelf room 9. At that time, the seedling raising box 5 is transferred from the conveyor IIB to IIA by being pushed by hand, and from there, the seedling raising rack 5 is placed on an appropriately selected seedling raising shelf 10.
It is placed on an empty shelf. The seedlings that have grown to about 2 cm are placed in a state where they are not shaded from light from the time they are placed on the seedling raising shelf 10, but since they require direct sunlight for about a day from the day before shipping, they are divided into four stages. The seedlings are placed on the first to third shelves from the bottom, which are partially shaded by the seedling boxes placed on the upper shelf, avoiding the topmost shelf that receives the most sunlight. Thereafter, the seedlings are kept in the same position until the day before shipping, and the seedlings are placed in sunlight for a while and are watered with liquid fertilizer a total of 9 to 10 times to carry out photosynthesis and grow into the above-mentioned young vegetables. In addition, watering is performed in a mist state when the seedlings are young, and in a shower state as the seedlings grow, depending on the degree of growth of the seedlings.

The young vegetables are exposed to direct sunlight one day before being shipped, and the leaves turn a bright green color. Therefore, by the afternoon of the day before shipping, that is, on the fifth day after sowing, each seedling raising box 5 is moved to the top shelf. The daikon radish is then shipped from the morning to the afternoon of the sixth day, but only those shipped in the afternoon receive watering for the 10th time. In this way,
Approximately two days after sowing, the seedlings are placed in a well-lit shelf room under indirect and direct sunlight until the day of shipment.

By the way, except for one week to 10 days in early autumn, when it is the best time for cultivation, daikon radish is shipped on the 6th day after sowing in all seasons, and as it grows quickly during the above mentioned period, it is shipped on the 5th day. Ru.

Shipping is performed as described below. First, the seedling growing box 5 on the top of the seedling growing shelf 10 is placed on the conveyor IIA, and is conveyed to the backing workbench 13 by the shipping conveyor 12. In one compartment of the seedling nursery box 5, a large number of daikon radishes of the same height are grown, and their roots are intertwined with each other and are also strongly attached to the bottom of the compartment. Therefore, the worker leans the seedling raising box 5 in a position that makes it easy to work, and
The cracked daikon radish in the plot is pulled out and packed into one polyethylene bank container with a shipping rate of one cracked radish.

Thereafter, the lid of the container is closed and secured in a section 15, the container is packed into a cardboard box and the bottom and top of the box are sealed in a section 16, and the cardboard box is stored in a cold storage 14. Ru. When the shipping containers arrive, the boxes are loaded and shipped to market in the evening.

〔Effect of the invention〕

As explained in detail above, the present invention comprises a step of absorbing water in a dipping tank and a germination room, a step of sowing the seeds in a seedling nursery box and germinating them in a light-shielded nursery room, and a step of allowing the seeds to absorb water in a soaking tank and a germination room, and a step of allowing the seeds to germinate in a light-shielded nursery room. We added a step to grow the young seedlings in a well-lighted shelf room in a well-lit shelf room until the day of shipping, as well as by watering them as appropriate, so the young seedlings were exposed to indirect sunlight for 2 to 3 days, and then for several days before being shipped. will be grown in direct sunlight. Therefore, the young seedlings can grow with sufficient sunlight for at least 3 to 4 days before shipping, and can be bathed for many days.As a result, the constitution and health condition of the daikon radish The result is stronger and better-quality fruits than those produced by conventional cultivation methods.For example, even in the harsh summer conditions, they can last for more than three days without wilting or rotting compared to other cultivation methods. We can provide people with high commercial value and economical use of daikon radish without waste throughout the year.In addition, daikon radish is grown in a healthy and clean manner, so after filling it in puncture containers, continues to grow and can be enjoyed as fresh food.
