Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a softening cultivation method for regenerating white young shoots from chicory roots.

(Prior art) Chicory is a plant belonging to the chrysanthemum family, and its softened white young shoots are often used in salads and the like.

To soften chicory and obtain white young shoots, sow the seeds in early summer, dig them out when the root diameter is appropriate, for example 3 cm or more, and place the seedlings with about 2 cm of leaves in a hole in a warm place such as a greenhouse. dig and bury. At this time, cover not only the roots but also the leaves with soil, protect them from sunlight, and warm them to 18 to 20 degrees Celsius to allow the leaves to regenerate.

(Problem to be solved by the invention) When chicory is covered with soil and softened, soil may enter the inside of the leaf, reducing its commercial value.

Chicory cultivation is carried out under warm conditions, so if pathogens are present in the soil where chicory seedlings are buried, they will be cultured and propagated, infecting a wide range of seedlings.

If you cut the leaves at about 2 cm from the roots and leave the leaf part other than the core bud, the remaining leaf parts often contain pathogenic bacteria, and the regenerated young buds may also become infected. be.

The present invention relates to a method for softening chicory cultivation, and aims to provide a method that does not use soil and is resistant to infection by pathogenic bacteria.

(Means for Solving the Problems) In the present invention, at least the area where leaves are to be regenerated of a chicory seedling from which leaves other than the core bud part have been removed is surrounded, and moisture is supplied from the roots without using soil. Regenerate leaves in the dark. The member surrounding the area where leaves are regenerated may be non-elastic;
It may be elastic.

In the present invention, the roots are also wrapped in a moisture-proof film except for the lower end.

In the present invention, chicory seedlings from which leaves other than the core bud have been removed, at least surrounding the area where the leaves will be regenerated, are arranged vertically in a container, filled with water, and placed in a dark place. Regenerate leaves.

(Action) Chicory roots can regenerate leaves by supplying water and keeping at a moderate temperature. By enclosing the area where the leaves are to be regenerated, as the young shoots grow, the enclosing member prevents them from spreading outward, resulting in young shoots with densely packed leaves. When the surrounding member is made of an elastic member, the shape of the young buds becomes better.

Leaves other than the young buds are often contaminated with pathogens, so remove them.

If chicory is grown in strong light, the leaves will turn green and the bitterness will be stronger, but if chicory is grown in the dark, the leaves will turn white and the bitterness will be weaker.

If you wrap all parts of the root except the lower end with a film that does not allow water to pass through, the film will not supply moisture to the part of the root, so hair roots will not form, and hair roots will only form at the lower end of the root. do.

(Example) Chicory seeds are sown in early summer and dug out when the root diameter is about 3 cm or more. Remove all parts of the leaves except the core bud. Chicory seedlings can be stored in a cool, dark place below 5°C, preferably near 0°C, without causing buds to grow.

Cut the lower end of the root 2 of the seedling, leaving the core bud 4, and root 2.
Set it to an appropriate length, for example, about 15 to 20 cm. The seedlings in this state are soaked in a calcium chloride aqueous solution overnight.
This is to replenish calcium, as seedlings grown in Japanese soil often lack calcium. For example, in the case of seedlings grown in calcareous soil like in Europe, calcium chloride No need to soak in aqueous solution.

After that, as shown in FIGS. 1 and 2,
The circumference of the root 2 and the upper part of the core bud 4 are wrapped with an elastic member 6. The space formed above the core bud 4 is an area where leaves are regenerated. As the elastic member 6, a sponge having a thickness of several mm to 1 cm, for example about 5 mm, can be wound.

Between the sponge 6 and the root 2, there is a lower end 2a of the root 2.
A resin film, such as a polyethylene film, which does not allow water to pass through, is wrapped around the film 8. The film 8 is preferably, for example, a so-called anti-fog film that has been treated to prevent water droplets from adhering to it.

Wrap the outside of the rolled sponge 6 with paper 10 to prevent it from loosening.

The chicory seedling wrapped in the sponge 6 is stood vertically so that the lower end 2a of the root is submerged in water, placed in a dark place, and kept at a temperature higher than 5°C, for example, 18 to 20°C. Fertilizer components may be dissolved in the water. As the fertilizer components, nitrogen, phosphorus, and potassium are used, and if necessary, boron, manganese, iron, copper, zinc, molybdenum, etc. may be dissolved in trace amounts.

Eventually, the core bud 4 grows and becomes a white young bud 4a, which becomes thicker than the inner diameter of the tube of the sponge 6, as shown in FIG. The leaves become tightly packed.

Moisture is not supplied to the part of the root 2 wrapped in the film 8, but only from the tip part 2a of the root, and hair roots 2b grow only in the tip part 2a.

If the film 8 is also wrapped around the part where the young buds 4a grow, the young buds 4a tend to grow thinner and longer.On the other hand, if the film 8 is not wrapped around the part where the young buds 4a grow, the young buds 4a tend to grow thinner and longer. They tend to grow thick and short.

In the state shown in FIGS. 1 and 2, the moisture-impermeable film 8 can also be omitted. In that case, water is supplied to the upper part of the roots 2 through the sponge 6, which is an elastic member, and hair follicles are generated over the entire roots 2.

The elastic member 6 is not limited to a sponge. Young bud 4
Any material may be used as long as it can prevent the young shoots 4a from spreading by applying pressure inward when the young shoots 4a grow.

Surrounding the area where leaves are regenerated is not limited to an elastic member. For example, it may be made of a plastic tube or may be made of paper wrapped in many layers.

The elastic member 6 and other surrounding members do not need to cover the entire root 2, but may surround only the area where leaves are regenerated as young shoots 4a, or only the area including the upper part of the root 2.

In addition, although chicory seedlings are wrapped around a sheet-like elastic member 6 in Figures 1 and 2, it is also possible to make a cylindrical body out of an elastic member or other material and cover the area where the leaves will be regenerated. It's okay.

The chicory seedlings shown in FIGS. 1 and 2, wrapped with an elastic member 6 such as a sponge, are stored upright in a container 14 as shown in FIG. 4, and the bottom part is filled with water. . 12 represents a chicory seedling wrapped with an elastic member. As the container 14, for example, a container called a tangerine container can be used. For orange containers, the bottom depth is 3.
It can store water up to about 1 cm.

The inside of the container 14 is divided by a frame 18 so that the wrapped chicory seedlings 12 do not fall down inside the container 14. It is convenient to avoid arranging the wound chicory seedlings 12 in one area 20 surrounded by the frame 18 so that the supply of water and the presence or absence of water at the bottom can be confirmed.

For example, with a container 14 as shown in FIG.
Assuming 30cm, let the length of the root of the seedling 2 be 15cm, and the height of the rolled chicory seedling 12 be 30cm. If the young shoots 4a grow and the tip reaches the upper end of the sponge 6, then they are shipped, which makes management easier.

At the bottom end of the thing 12 wrapped with chicory seedlings,
A cylinder 22 as shown in FIG. 5 may be fitted and arranged in the container 14 in this state. The tube 22 allows the chicory seedlings 12 to be vertically erected, eliminating the need for a frame 18 as shown in FIG. If the tubes 22 are square tubes, they can be arranged regularly, which is even more convenient. The cylinder 22 is made of plastic, for example.

If the length of the tube 22 is, for example, about 15 cm, the length of the root 2 is also about 15 cm, and the sponge 6 is mainly wrapped only around the root 2, the state shown in FIG. 6 will be obtained. In this case, the sponge 6 connects the root 2 to the tube 22.
This is a filling material for fixation within the container, and other materials such as old newspapers may also be used. In the state shown in FIG. 6, the top of the tube 22 is covered with a cap 24 that surrounds the area where young shoots are to be regenerated. As shown in FIG. 7, the cap 24 is provided with legs 26 for fitting into the tube 22. The cap 24 is made of plastic, for example, and holes are provided to prevent water vapor from accumulating inside. Good.

The cap 24 is S,
Prepare different sizes such as M and L and use them depending on the size of the mother plant (root). If the time point when the young shoots grow and reach the cap 24 is used as a guideline for the shipping point, the shipping point can be easily managed.

The tube 22 fitted in this way is, for example, the eighth
They may be arranged in the container 14 as shown in the figure. The tip of the cap 24 serves as the container 14.
If containers 14 are deep enough so that they do not come out, containers 14 can be stacked.

Chicory seedlings or chicory seedlings wrapped in sponge can also be grown in containers such as hydroponic beds. For example, as shown in Figure 9, a sponge 12 wrapped around the hydroponic bed 28
Alternatively, if you fit a tube into the bottom end of the bed to make it easier to line them up, supply water to the hydroponic bed 28, and cover it with a black sheet to prevent light from entering, you can leave it outdoors. .

A container such as a hydroponic bed 28 is covered with a lid 32 having a hole 30 as shown in FIG. 10, and a chicory seedling with a core bud left is inserted into the hole 30. Several types of holes 30 are prepared depending on the size of the roots 2 of the chicory seedlings. As shown in FIG.
A guide portion 34 for vertically supporting the root 2 is provided on the lower (or upper) side of the hole 30, and a cap 36 is placed over the top of the hole 30. Like the cap 24 shown in FIGS. 6 and 7, this cap 36 is also sized to meet shipping standards. Water 38 is put into the hydroponic bed 28.

Containers lined with chicory seedlings can be cultivated by placing them in a light-shielded greenhouse, for example.

(Effects of the Invention) In the present invention, the area where the leaves of chicory seedlings are regenerated is surrounded, and the young shoots are allowed to grow in a dark place while preventing them from spreading outward, compared to the method of covering with soil and softening it. The young buds that are regenerated by this process will not become contaminated with soil. If the surrounding member is made of an elastic material, the shape of the young bud will be improved.

In the present invention, since leaves other than the core bud portion are removed, there is no need to sterilize the seedlings, and there is no risk of contamination with fungicides.

In the present invention, cultivation is performed using water without using soil, so infection with pathogenic bacteria is less likely.

Wrapping the roots other than the lower end of the root with a film that does not allow moisture to pass through can prevent hair roots from growing outside the lower end of the root, increasing the commercial value of products with roots attached. . If the plant has roots, you can eat the young buds, and if you leave the new buds and keep them out of strong light, you can regenerate them at home and make them bloom.

Chicory seedlings wrapped in tubes can be moved by simply standing them up in containers such as tangerine containers or hydroponic beds, and the containers can also be stacked, eliminating constraints on cultivation space. There are also some advantages. If you line up chicory seedlings wrapped in elastic material in a container, you can easily see how the young shoots are growing. If the conventional softening method was to bury the buds in the soil, it would be difficult to manage them because it would be impossible to tell how the young buds were growing until they were dug up.
