Description

  The present invention relates to a method for preserving seedlings of the genus Euphorbiaceae.

  As the plant of the genus Euphoridae, there are known Lipia nodiflora, Lippia canescens, and improved species thereof.

  As a method for preserving such a plant, after allowing the stem to grow on the water-permeable sheet, the sheet is cut at a predetermined width, the cut sheet is wound into a roll, and the temperature is 0 to 1 degree Celsius, It is known to be placed in an environment where the humidity is 90% to 100% (see, for example, Japanese Patent Laid-Open No. 2002-330626, paragraphs [0023] to [0025], FIGS. 1 and 3).

  However, in the conventional storage method, since the stem itself proliferated on the sheet is stored, the storage amount per unit volume is small as compared with the case of storing the seedling obtained by cutting the stem. Further, since the stem itself is stored together with the sheet, a large storage space is required. In addition, when the seedling obtained by cutting the stem is placed in an environment where the temperature is 0 ° C. to 1 ° C. and the humidity is 90% to 100%, water vapor in the air forms ice crystals on the surface of the seedling. It is highly probable that frost will dry out due to condensation, so that even if it is returned to room temperature during use, sufficient growth cannot be obtained thereafter.

JP 2002-330626 A

  An object of the present invention is to provide a method for preserving seedlings of the genus Euphorbiaceae, which can increase the amount of storage per unit volume and can obtain sufficient growth after storage. is there.

  In order to solve the above-mentioned problems, the present invention provides a container that is sealed after adding a seedling of a plant of the genus Euphorbiaceae and a moisture regulator, with a temperature of 2 to 7 degrees Celsius and a humidity of 20 to 50%. Provided is a method for preserving the seedling, characterized by being placed in an environment.

  According to the preservation method of the present invention, since the seedling obtained by cutting the stem is preserved, the preservation amount per unit volume can be increased compared to the conventional method of preserving the stem itself before harvesting. It becomes possible. Moreover, since it is the structure which preserve | saves a moisture adjusting material with a seedling, compared with the conventional method which preserve | saves stem itself with a sheet | seat, a big preservation space is not required. Furthermore, since the seedlings are stored in an environment where the temperature is 2 to 7 degrees Celsius and the humidity is 20% to 50%, the seedlings are not frosted and the frost does not dry out. Growth can be obtained.

  In the preservation | save method which concerns on this invention, the seedling of the plant of the genus Oleaceae Iwadaresou is made into the preservation | save object. Here, as the plant of the genus Euphoridae, the genus name “S Hitoshi” (variety registration No. 12041), which is an improved species of Lipida nodiflora, Lippia canescens, and improved species thereof, for example, Registered on March 15, 2004).

  Since the plant of the genus Euphorbia roots from a node, the seedling is obtained by cutting a stem into a predetermined length so as to include the node.

  As a method for collecting seedlings, the stems of the genus Euphorbia have the property of extending so as to crawl on the ground, and thus a method of cutting and collecting the stems extending in the horizontal direction in this way is common. In the present invention, seedlings collected by such a collection method are not excluded, but such collection methods have the following problems.

  That is, a large cultivation area is required to extend the stem. Further, since the roots are rooted from each node in the process of extending the stem, there is a problem that the seedlings are easily damaged and the collected seedlings are also large. Further, since the stem grows while bending, it is difficult to collect a straight seedling.

  Therefore, as a method for collecting seedlings, a method is preferable in which a stem hanging from a seedbed installed at a predetermined height is cut to a predetermined length and collected. In this method, as shown in FIG. 1, a seedbed 20 is set at a predetermined height, and seedlings of the genus Euphorbia plant 10 are planted on the seedbed 20. The stem 30 extending from the seedling planted on the seedbed 20 overflows from the seedbed 20 and grows in the vertical direction. And at the time of seedling, the stalk 30 extending vertically from the nursery bed 20 is cut into a predetermined length so as to include a node, and the seedling is collected.

  According to this sampling method, since the stem 30 extends in the vertical direction, there is an advantage that a large cultivation area is not required to extend the stem 30. In addition, the stem 30 hanging from the seedbed 20 exists in the air and has very little rooting from each node, so that it is possible to collect small, high-quality seedlings without rooting. Moreover, since the stalk 30 extending in the vertical direction extends straight compared to the stalk extending in the horizontal direction, it is possible to collect a straight seedling with less bending. Further, since the nodes are easy to see when the stem 30 is cut, the cutting operation is easy. Also, the seedling obtained by cutting the stem 30 falls after the cutting, so the seedling collecting operation is easy.

  Note that, for example, a plurality of nurseries 20 can be installed in a staircase shape as shown in FIG. 2A, or a plurality of nursery beds 20 can be installed in a hierarchical shape as shown in FIG. 2B. . If the seedbed 20 is installed in this way, a large amount of cultivation can be performed in a smaller area, and more seedlings can be collected.

  The moisture adjusting material can retain moisture necessary for the survival of the seedling, and supplies the retained moisture to the seedling and also absorbs moisture released from the seedling. The moisture adjusting material is not particularly limited as long as it can perform such a function. For example, it is a kind of wood waste, bark fiber (wood waste, coconut shell, cedar skin, etc.) or earth (including organic matter). Or a mixture thereof can be used. The moisture adjusting material is not limited to a natural material, and may be an artificial material.

  The container may contain a seedling and a moisture adjusting material and can be sealed or can be in a state close to sealing. As the container, for example, a plastic bag, specifically, a bag made of a material such as vinyl, polyethylene, or polypropylene can be used, and a container having antifogging properties is preferable. By using a container with antifogging properties, it is possible to effectively prevent the seedling from being spoiled by dripping water droplets adhering to the inner surface of the container onto the seedling.

  In the preservation method according to the present invention, the seedling of the genus Euphorbia and the moisture adjusting material are placed in a container, and then the container is sealed. Here, the seedling is about several centimeters in size, but if the seedling collected by the above-described collection method is used, there is no rooting and the shape is straight, so it can be accommodated in a large amount in a container. it can. Therefore, the storage amount per unit volume can be increased. Further, the amount of the moisture adjusting material to be put into the container is sufficient if the weight ratio mixing ratio with respect to the seedling is 10% to 30%. When the weight ratio of the moisture adjusting material is less than 10%, the moisture necessary for the survival of the seedlings cannot be retained, and the moisture released from the seedlings cannot be sufficiently absorbed. On the other hand, when the weight ratio mixing ratio of the moisture adjusting material exceeds 30%, excess moisture is stored and the storage amount of the seedling is reduced. Therefore, it is preferable to adjust the amount of the moisture adjusting material within the above range. In this invention, since it is the structure which preserve | saves moisture adjustment materials, such as a wood chip, with a seedling in this way, there exists an advantage that a big storage space is not required.

  The container that is sealed after the seedling and the moisture adjusting material are placed is placed in an environment where the temperature is 2 to 7 degrees Celsius and the humidity is 20 to 50%. By placing the seedlings in such an environment, the seedlings can be stored in a alive state while suppressing the growth of the seedlings. Further, since the humidity is as low as 50% or less and the temperature is adjusted to 2 degrees to 7 degrees Celsius, the seedlings are not frosted, and therefore frost can be prevented. The illuminance is preferably adjusted within a range of 0 lux to 700 lux. By adjusting the illuminance within such a range, the growth of the seedling is moderately suppressed.

  As a more preferable environment for storing seedlings, the following environmental conditions were found as a result of experiments. That is, (1) a container that has been sealed after adding seedlings and a moisture regulator is placed in an environment where the temperature is 2 to 7 degrees Celsius and the humidity is 20 to 50%, or (2) the container is Place in an environment with a temperature of 3 to 6 degrees Celsius and a humidity of 20 to 40%. Under any of the environmental conditions, the seedlings were not frosted, and therefore the seedlings were not frosted, and the seedlings could be preserved in a viable state while suppressing the growth of the seedlings. The growth of seedlings after storage was also good.

  Examples of the present invention will be described below, but the present invention is not limited to the examples described below.

In the present example, first, seedlings were collected from the genus Euphorbia plant 10 cultivated using the cultivation apparatus shown in FIG. That is, the seedling to be preserved is obtained by cutting the stem 30 hanging from the nursery bed 20 installed at a predetermined height into a predetermined length.
Wood chips were used as the moisture adjusting material. The container used was a vinyl bag having antifogging properties.

  First, the mixture of the seedling and the moisture adjusting material was put in a container. At this time, the mixing ratio of the moisture adjusting material to the seedling was 10% to 30%. Next, after adding a suitable water | moisture content to the moisture adjusting material, the container was sealed. The sealed container was placed in an environment where the temperature was 2 to 7 degrees Celsius and the humidity was 20 to 50%, and stored for 6 months. The illuminance was adjusted within the range of 500 lux to 700 lux.

  After storage, the container was opened, and the seedlings were taken out and observed. As a result, there was no frost-drying and rooting was suppressed. When the seedlings were planted, the rooting condition was good and the subsequent growth was also good.

  According to the present embodiment, seedlings can be stored in good quality for a period of 6 months or longer, so that it is generally possible to supply seedlings even when it is difficult to collect seedlings or during fallow periods. . Further, there is an advantage that a storage space is small and a large amount of high-quality seedlings can be stored.

  In this embodiment, the environmental conditions for placing the container containing the seedling and the moisture adjusting material are different from those in the first embodiment. That is, in this example, the sealed container was placed in an environment where the temperature was 3 to 6 degrees Celsius and the humidity was 20 to 40% and stored for 6 months. The illuminance was adjusted within the range of 0 lux to 10 lux.

  After storage, the container was opened, and the seedlings were taken out and observed. As a result, there was no frost-drying and rooting was suppressed. When the seedlings were planted, the rooting condition was good and the subsequent growth was also good.

  According to this example, as in Example 1, seedlings can be stored in a good quality state for a period of 6 months or longer, so that seedlings can be removed even when it is generally difficult to collect seedlings or during fallow periods. It becomes possible to supply. Further, there is an advantage that a storage space is small and a large amount of high-quality seedlings can be stored.

  According to the present invention, high-quality seedlings can be stored over a long period of time, so that it is possible to supply seedlings even at times when it is generally difficult to collect seedlings or during fallow periods.
