Description

The present invention relates to natural moss (Nagaimo, Ginkgo biloba, Dioscorea opposita Thunb), Dioscorea (Dioscorea).
aponica Thunb), etc.) belongs to the technical field related to the method of growing the baskets that occur as side buds of leaves.

  Mukago is harvested and used as a foodstuff itself, and also used as a seed for planting natural pods, etc., but because it is a small lump, its product value as a foodstuff is low and it grows to a size that allows natural potatoes to be shipped. It takes years to make it happen. Therefore, development of a growing method for enlarging the basket into large blocks has been demanded.

  Conventionally, as a method for growing a basket, for example, a method described in Patent Document 1 is known.

  Patent Document 1 describes a method for growing a basket in which, when a basket is generated in a grown natural moth, the root is absorbed from the basket by covering the basket with soil, and the basket is grown as a natural moth. .

  The method for cultivating a basket according to Patent Document 1 is intended to shorten the number of years for growing a natural basket etc. to a size that can be shipped by immediately cultivating the generated basket like a seed pod of a natural basket.

JP 2009-247259 A

  In the method for cultivating a basket according to Patent Document 1, the basket is cultivated like a planted seed pod such as a natural basket, and therefore, there is a problem that the basket itself cannot be harvested as food. In addition, a nursery for covering the basket with soil must be formed, and the soil covering state for the basket must be managed.

  The present invention has been made in consideration of such problems, and an object of the present invention is to provide a method for growing a basket that can enlarge the basket as it is into a large lump without taking time and effort.

  In order to solve the above-described problems, the basket growing method according to the present invention employs means described in each of the claims.

  That is, according to claim 1, when a flower that has bloomed in a grown natural moth is withered, the stem and leaves are excluded except for light, and the temperature is 15 to 50 ° C. and the humidity is 60% or more for 7 to 100 days. It is characterized by nurturing.

  With this means, by controlling the temperature and humidity by shading, the generated basket can be covered with soil in the same manner as the basket growing method according to Patent Document 1, and a part of the shading can be prevented. By avoiding this, the generated basket can be supplied with starch by photosynthesis of the leaves.

  Further, according to claim 2, in the method for growing a basket of claim 1, when a flower basket that has blossomed in a grown natural moth has withered and the basket has grown, it is shielded from light until the basket grows to a diameter of 5 mm at the latest. , It features a humidity environment.

  With this means, shading or the like can be performed not only immediately after the flowers that have grown on the grown natural moths have withered, but before the basket has developed and has reached a certain size.

  Further, according to claim 3, in the method for cultivating the cage of claim 1 or 2, when the flower that blooms in the natural pods that have been planted and grown on an outdoor plantation dies, the stem and leaves are partially covered. It is characterized in that the basket is shielded by covering with a material to avoid a sudden change in temperature environment and humidity environment, and the covering material is removed at the beginning of autumn after the summer.

  In this means, when growing outdoors, a covering material is selected as a means for performing light shielding and a means for managing temperature and humidity.

  Moreover, in Claim 4, in the growing method of the basket of Claim 3, the sheet | seat which has a light shielding rate of 20 to 80% is used as a coating | covering material, The upper end part and lower end part of the sheet | seat which covered the stem and the leaf It is characterized by narrowing down with a string material.

  In this means, a covering processing work generally performed in farm work is performed by covering with a covering material made of a sheet and a string material.

  In the basket growing method according to the present invention, the generated basket can be covered with soil in the same manner as the basket growing method according to Patent Document 1 by shielding light and controlling the temperature and humidity. By avoiding a part of the shading, the generated basket can be supplied with starch by photosynthesis of the leaves, so that the basket can be enlarged as it is into a large lump. Moreover, since troublesome work such as covering the basket with soil is unnecessary, there is an effect that the implementation is not troublesome.

  Furthermore, as claimed in claim 2, since it is possible to carry out shading etc. not only immediately after the flower that has blossomed in the grown natural moths has withered but until the size of the basket has reached a certain size, depending on the varieties of natural moths There is an effect that a suitable execution time such as shading can be selected.

  Further, as claimed in claim 3, when growing outdoors, a covering material is selected as a means for performing light shielding and a means for managing temperature and humidity.

  Further, as claimed in claim 4, since the covering is performed with the covering material made of the sheet and the string material, the covering processing work is generally performed in the farm work, and therefore, there is an effect that the implementation is easy.

BRIEF DESCRIPTION OF THE DRAWINGS It is a side view of the natural pod which grew of the 1st example of the form for implementing the cultivation method of the basket which concerns on this invention, (A) shows the growth state of a natural pod as it is, and (B) shows the growth state of a natural cocoon. A state in which the coating process is performed is shown (including a partially enlarged cross section). It is a calendar which shows the time of implementing the covering process of Drawing 1 (B). It is the photograph of the basket raised by FIG. It is side surface sectional drawing of the cultivation equipment of the 2nd example of the form for implementing the cultivation method of the basket which concerns on this invention.

  Hereinafter, the form for enforcing the basket growing method concerning the present invention is explained based on a drawing.

  1 to 3 show a first example of an embodiment for carrying out a basket growing method according to the present invention.

  In the first example, the one applied to the outdoor cultivation of the natural basket 5 is shown.

  As shown in FIG. 1 (A), natural pods die so that the white flowers that bloomed in early summer will turn yellow when stems 3 grow from seed pods 2 planted on cropland 1 in early spring and leaves 4 grow. As a side bud of the leaf 4, a small basket 5 is generated.

  In the first example, the stem 3 is attracted upward by an upright support for the growth of natural pods. Preferably, a net is stretched to facilitate the covering of the covering material 6 described later, and the side stems (children) of the stem 3 are stretched. Avoid attracting vines to the side.

  When the basket 5 is generated in the grown natural pod (until the diameter of the basket 5 grows to about 5 mm at the latest), as shown in FIG. 1 (B), the lower part of the stem 3 (main stem, side stem) is removed. It is covered with the covering material 6 together with the leaves 4 so as to be bundled. At this time, the stem 3 hanging downward is covered with the covering material 6 so as to be pulled up. As a result, the basket 5 is also covered with the covering material 6. In addition, a certain degree of basket 5 is exposed and left in the upper part of the stem 3 not covered with the covering material 6.

  In addition, in the varieties that normally do not generate the basket 5 as a side bud, the covering material 6 is coated when the flower is dead. Moreover, also in the varieties in which the basket 5 as a side bud is generated, the coating material 6 can be coated when the flower before the basket 5 is generated is withered. In either case, the basket 5 is generated by the light shielding by the covering material 6. Therefore, it is possible to select a suitable execution time such as shading according to the natural varieties.

  The covering material 6 has a light shielding property (light shielding rate is 20 to 80%) in which a black aluminum foil backing 6b is laminated on a white surface material 6a made of, for example, a synthetic resin material, a cloth material, or a paper material. It consists of a sheet | seat (refer FIG.1 (B) enlarged cross section). About the covering material 6 which consists of a sheet | seat, it is preferable to have waterproofness and heat insulation. The covering material 6 made of this sheet is suitable for covering so as to wrap the stem 3 and the leaf 4. A covering material 6 made of a sheet covering the stem 3 and the leaves 4 is held at its upper end and lower end by being tied with a string material 7. The string material 7 restricts the upper and lower ends of the covering material 6 so as not to damage the stems 3 and leaves 4, thereby suppressing the inflow of outside air into the covering material 6. The covering with the covering material 6 and the string material 7 made of such a sheet is a covering operation generally performed in farm work. Therefore, it is easy to implement without requiring a special work technique.

  The height b of the lower part of the stem 3 covered with the covering material 6 is set shorter than the height a of the upper part of the stem 3 not covered with the covering material 6. Preferably, the height a to the height b is about 2 to 1. In addition, since the basket 5 is not generated only on the main stem, the covering material 6 is not covered on the stem 3 having a height c of about 40 to 50 cm from the cropping 1.

  Covering with the covering material 6 is continued during the summer.

  Then, the covering material 6 is removed at the beginning of autumn when the sunshine time is shortened and the temperature is lowered so that the growth of the basket 5 cannot be expected, and the basket 5 covered with the covering material 6 is harvested as necessary. become.

  As shown in FIG. 3, the harvested basket 5 is a spherical small lump that is enlarged into a bowl-shaped large lump. FIG. 3 shows a state in which the covering 6 made of a sheet is opened, and it is confirmed that a plurality of baskets 5 are growing on the stem 3 extending vertically. Compared to the case where the covering 6 is not applied, the basket 5 is enlarged to a size two to three times larger. As is clear from FIG. 3, the leaves 4 covered with the covering material 6 are withered or yellowed.

  The enlargement of the basket 5 is shaded as if it were covered with soil as in the basket growing method according to Patent Document 1 to enhance the starch accumulation function (however, since there is no medium, the absorption root and the storage root are generated). The roots are only slightly seen), and it is thought to be realized by the fact that the starch produced by the photosynthesis of the leaves 4 in the upper part of the stem 3 can be fully fed through the stem 3. In addition, prevention of a sudden change in the temperature and humidity around the basket 5 by the covering of the covering material 6 is also helpful in providing an environment covered with soil. That is, it has been confirmed that if the height a of the upper portion of the stem 3 not covered with the covering material 6 is shortened, the basket 5 is not sufficiently enlarged. Moreover, when the shading rate of the covering material 6 is less than 20%, the color of the basket 5 becomes green instead of white having a high commercial value, and the starch accumulation function is lowered and the basket 5 is enlarged. It has been confirmed that crystallization is reduced. Moreover, when the shading rate of the covering material 6 exceeds 80%, the stem 3 and the leaf 4 are suddenly withered, the supply of starch through the stem 3 is hindered, and the enlargement of the basket 5 is reduced. It has been confirmed.

  Furthermore, it has been confirmed that the harvested basket 5 is hardly damaged by pests (A. suzukiella, Acrolepiopsissnagaimo, etc.).

  In order to avoid harming the insects in the basket 5, some roots of the cage 5 are covered with the covering material 6 under the same temperature and humidity conditions as the ground, but the roots of the basket 5 are rooted. It is thought that substances etc. are influencing. In addition, when the covering material 6 made of a sheet has heat insulation properties, it is possible to prevent the temperature around the basket 5 from becoming unnecessarily high during the daytime in the summer and to surround the basket 5 at the night in the summer. The decrease in temperature can be reduced.

  Furthermore, if the covering material 6 made of a sheet has waterproofness, unnecessary water wetting of the basket 5 covered with the covering material 6 can be prevented during a long rain. Further, the lower end portion of the covering material 6 is a string material 7 and a stem 3. Since it is narrowed down with a small gap so as not to damage the leaves 4, even if rainwater flows into the inside of the covering material 6, it is discharged from the lower end portion without stagnation inside. Therefore, the basket 5 is not deposited in the rainwater stagnated inside the covering material 6.

  According to the first example, it is possible to harvest the basket 5 that has been enlarged in the shape of a bowl-shaped lump at the beginning of autumn, and it takes years to grow the basket 5 to a size that can be shipped with high commercial value as a food ingredient. Disappear. Moreover, the productivity of the basket 5 is improved by avoiding the harmful insects of the basket 5 being harvested.

  As the covering material 6 used in the first example, a single-layer sheet avoiding black, red and brown colors can be used. Moreover, it is also possible to use a container-shaped body that can cover the stem 3 and the leaf 4 with a single touch as the covering material 6.

  FIG. 4 shows a second example of an embodiment for carrying out the basket growing method according to the present invention.

  In the 2nd example, what is applied to indoor raising of the basket 5 of a natural selection is shown.

  The second example includes a house 8 having a light-shielding property surrounding a natural fence planted on the plantation 1, an air conditioner 9 having a temperature adjustment function and a humidity adjustment function, and an illuminator 10 attached to the house 8. Use breeding equipment. In addition, as the illuminator 10, one having directivity (straightness) like an LED light is selected.

  In this growing facility, as in the first example, when the flowers wither, the entire stem 3 and leaves 4 are shielded from light by the house 8, the temperature inside the house 8 is 5 to 50 ° C., and the humidity is 60% or more. Such an environment is maintained, and illumination by the illuminator 10 is applied only to the upper stem 3 and leaves 4.

  As a result, it becomes possible to harvest the basket 5 that has been enlarged into a large lump by growing for 7 to 100 days. In addition, if the humidity is 60 to 80% that approximates the humidity of the soil and the temperature is maintained near 30 ° C., the basket 5 that is enlarged to some extent in 7 days can be obtained. Further, to obtain the same enlargement as the first example, it is necessary to grow for 100 days close to the first example. Incidentally, in order to obtain the basket 5 having a high commercial value such as taste and texture in addition to enlargement, it is preferable to maintain the temperature at 25 to 30 ° C.

  As described above, in addition to the examples shown in the drawings, it is possible to shield the light other than the lower part of the natural selection and remove the light other than the upper part of the natural selection.

  When the above-described method for carrying out the basket raising method according to the present invention is carried out in the plains of Tochigi Prefecture, the seedling 2 is planted on the plantation 1 around April 10th, and the basket 5 is generated. Will be around July 20th. And removal of the covering material 6 will be around September 15th.

  The method for cultivating a basket according to the present invention can be widely applied to a natural cage that can generate a cage other than a natural cage.
