[Cultivation method]
The method for cultivating Brussels sprouts according to an embodiment of the present invention includes a cultivation step in which a culture solution is applied to the roots of Brussels sprouts and hydroponically cultivated. The method for cultivating Brussels sprouts may further include various steps until the non-headed Brussels sprouts are harvested, such as a seedling raising step, a secondary seedling raising step, and a planting step.

According to the method for cultivating Brussels sprouts according to an embodiment of the present invention, a novel harvest (new leaves generated from the cut end of lateral buds), which is difficult to obtain when hydroponically cultivating Brussels sprouts. ) Can be obtained stably and continuously. In addition, the lateral buds (Brussels sprouts) that are removed to obtain this new crop have the same quality that can be used in soil cultivation, so that more lateral buds are added on a continuous basis. It is possible to harvest. That is, according to one embodiment of the present invention, a new harvest product derived from non-heading Brussels sprouts can be brought about, which can contribute to the expansion of its use as a food material. In addition, it can contribute to the stable supply of lateral buds (non-Brussels sprouts).

<Non-heading Brussels sprouts>
As used herein, the term "Brussels sprouts" broadly refers to Brussels sprouts varieties whose lateral buds do not exhibit heading. Typically, it refers to a Brussels sprout variety whose lateral buds do not show heading, which is produced by crossing Brussels sprouts and kale. In this case, usually, Brussels sprouts are mated with maternal and kale as paternal. Examples of non-heading Brussels sprouts are Minivale No. 8 (variety registration No. 20651), Minivale No. 6 (variety registration No. 6145), and Minivale No. 3 (variety registration No. 5249) known as Petit Veil (registered trademark). No.), etc., but not limited to this, Petit Vert Rouge (trade name of Masuda Seed Co., Ltd.), Petit Vert White (trade name of Masuda Seed Co., Ltd.), etc. are also included.

In the present specification, Brussels sprouts are classified as Brassica oleracea L var. Gemmifera and mean plants whose lateral buds are heading. As used herein, kale means a plant classified as Brassica oleracea L var. Acephala or Brassica oleracea L convar. Acephala. In addition, non-heading Brussels sprouts are typically classified as Brassica oleracea L var. Gemmifera or as a hybrid of Brassica oleracea L var. Gemmifera and kale in terms of plant classification.

<Hydroponic cultivation>
As used herein, the term "hydroponics" means that non-heading Brussels sprouts are cultivated using a culture solution containing water and nutrients without using soil. Examples of the method for cultivating non-heading Brussels sprouts by hydroponics include a submerged hydroponics method (DFT) and a thin film hydroponics method (NFT). DFT is a method of cultivating at least a part of the roots (roots) of Brussels sprouts by immersing them in a deep culture solution. NFT is a method of cultivating non-heading Brussels sprouts by continuously flowing a shallow culture solution through the roots. Further, the method of cultivating non-heading Brussels sprouts by hydroponics may be a method of planting non-heading Brussels sprouts in a cultivation bed and immersing the cultivation bed in a culture solution for cultivation.

<Seedling>
As used herein, the term "non-heading Brussels sprouts seedlings" means seedlings of non-heading Brussels sprouts that have been raised for the purpose of transplanting (that is, planting) in the future. The seedlings of Brussels sprouts to be planted are not particularly limited, but may be preferably seedlings having one or more true leaves, four or more, or six or more true leaves. In addition, the seedlings of Brussels sprouts to be planted may preferably be seedlings having 10 or less true leaves, 8 or less, 6 or less, and 2 or less true leaves. ..

<Culture>
As used herein, the term "culture solution" means a liquid containing nutrients necessary for plant growth. More specifically, the nutrient component is appropriately selected from the essential elements of the plant (major element and trace essential element), but may contain elements other than the essential element. Examples of the components contained in the culture solution include nitrogen, phosphorus, potassium, lime, magnesium, manganese, boron, iron, copper, zinc, molybdate and the like. Examples of commercially available culture solutions used in one embodiment of the present invention are OAT House Fertilizer A Formulation, OAT House Fertilizer SA Formulation, Amino House No. 1, and Amino House S1 manufactured by OAT Agrio Co., Ltd. And so on.

The culture solution may be an inorganic culture solution containing an inorganic fertilizer as a nutritional component, or an organic culture solution containing an organic fertilizer (organic solution cultivation. For example, refer to Japanese Patent Application Laid-Open No. 2007-119260). May be good. The pH and electrical conductivity (EC) of the culture solution are not particularly limited as long as they are pH and EC capable of growing non-headed Brussels sprouts. EC (S / m) is an index of the amount of elemental ions eluted in the culture solution, and represents a guideline for fertilizer concentration. The culture solution used in one embodiment of the present invention preferably has a pH in the range of 5.5 to 6.5 and an EC in the range of 0.8 to 1.2.

<Cultivation floor>
As used herein, the term "cultivation bed" means a support used as necessary to retain the underground tissue (root) of Brussels sprouts in order to grow Brussels sprouts. ing. Typically, seeds or seedlings are planted on the cultivation bed. The type of cultivation bed is not particularly limited, but it is preferable that it contains a soil substitute, and examples thereof include artificial soil such as vermiculite and a support made of natural or artificial fibers such as rock wool and coconut husk. An example of a commercially available cultivation bed used in one embodiment of the present invention is a rock wool bed manufactured by Nippon Rock Wool Co., Ltd. The seedlings to be planted on the cultivation floor may be accompanied by the seedling raising mat used at the time of raising seedlings. In this case, the seedlings are planted on the cultivation floor together with the seedling raising mat. An example of a commercially available nursery mat is Culture Mat Clean manufactured by Nippon Rockwool Co., Ltd.

It is preferable that the seedling raising mat is provided with a plurality of holes (for example, 10 to 1000 holes, 100 to 500 holes, 200 to 500 holes, 300 to 500 holes, etc.) for sowing seeds. The number of seeds to be sown in each hole of the nursery mat is not particularly limited, but for example, 1 or more is 10 or less, and 1 or more is 5 or less, and 1, 2, or 3 Alternatively, the number is more preferably four. In order to save the trouble of thinning, the number of seeds sown in each hole of the cultivation bed is one. The seedling raising mat is preferably cut so that it can be divided into each seedling raised. As a result, the seedlings can be planted on the cultivation floor together with the divided seedling raising mats.

(Seedling raising process)
In the seedling raising step, the method of growing (raising) non-heading bud cabbage seedlings is not particularly limited. For example, non-heading bud cabbage seeds are sown on a seedling raising mat provided in a cultivation container, and after germination, a predetermined method There is a method of raising seedlings until they become a plant (seedling) of a size. In the seedling raising step, for example, seedlings are raised until the number of true leaves of Brussels sprouts is about 1 to 2.

When sowing seeds on a seedling mat, it is preferable to initially irrigate the seedling mat before sowing the seeds. Examples of the method of initial irrigating the seedling raising mat include a method of immersing the seedling raising mat in water and a method of watering the seedling raising mat by a shower or the like.

After confirming the germination of seeds, the non-heading Brussels sprouts are given a culture solution and cultivated in a nutrient solution. The culture solution may be, for example, absorbed from the bottom surface of the seedling raising mat in which the seeds are sown, or the culture solution may be applied from the upper surface of the seedling raising mat.

The seedling raising process may be carried out in a facility such as a vinyl house, a tunnel, or a greenhouse, or may be carried out in an outdoor environment, but from the viewpoint of enabling the seedlings to be constantly supplied throughout the year. It may be more preferable to do it in the facility.

The seedling raising step may be carried out using soil instead of the above seedling raising mat.

(Secondary seedling raising process)
In the secondary seedling raising step, in the seedling raising step, non-heading Brussels sprouts that have not grown to a size suitable for planting but have grown to a predetermined size may be transplanted for secondary seedling raising. In the secondary seedling raising step, for example, seedlings are raised until the number of true leaves of Brussels sprouts is 4 to 6. When the secondary seedling raising step is carried out using a cultivation container, the same type as the cultivation container used in the seedling raising step may be used, for example, a cultivation container provided with a seedling raising mat.

The hydroponic cultivation conditions and the seedling raising environment for secondary raising of non-heading Brussels sprouts are the same as those in the seedling raising process. However, in the secondary seedling raising step as well as the seedling raising step, soil may be used instead of the above-mentioned seedling raising mat.

(Planting process)
In the planting step, the seedlings of Brussels sprouts raised in the seedling raising step or the secondary seedling raising step are planted in a facility for hydroponics (for example, a cultivation container). The cultivation container used in the planting step is, for example, a cultivation container provided with a cultivation bed. Before planting the seedlings, the cultivation bed used in the planting step may be filled with a culture solution having an EC of 0.8 to 1.2 within a pH range of 5.5 to 6.5 and be in a saturated state. preferable. When the seedling raising process or the secondary seedling raising process is performed using the seedling raising mat, the seedling raising mat used for the seedling raising step or the secondary seedling raising process can be cut into each seedling and planted together with the cut seedling raising mat on the satiated cultivation bed. Good.

(Cultivation process)
In the cultivation process, the roots of Brussels sprouts are hydroponically cultivated by feeding a culture solution. In the cultivation process, non-heading Brussels sprouts are hydroponically cultivated until they become a plant of a harvestable size. In the cultivation step, as shown in FIG. 1 (a) described later, hydroponics may be carried out for each seedling.

After planting non-heading Brussels sprouts seedlings in the planting process, for example, for non-heading Brussels sprouts seedlings, for example, from October to March, which is the winter season in Japan, 0.8 L / day to 1.5 L / day per plant. Irrigate an amount of culture solution (for example, 1.2 L / day), and culture in an amount of 2.1 L / day to 3.5 L / day (for example, 2.8 L / day) from March to September, which is the summer of Japan. Irrigate the liquid and cultivate it hydroponically. In this way, by managing the seedlings of Brussels sprouts so that the water content is high, it is possible to promote the survival of the seedlings. The culture solution to be irrigated after planting is, for example, a culture solution having an EC1.2 within the pH range of 5.5 to 6.5.

The hydroponic cultivation conditions for cultivating non-heading Brussels sprouts are not particularly limited as long as the non-heading Brussels sprouts can be grown into a plant having a harvestable size. For example, the environmental temperature is 15 ° C. to 25 ° C. It is in the range of ° C., and the light period is in the range of 8 to 12 hours. For example, in a greenhouse set up in Nagano prefecture, it is preferable to keep the daytime temperature at 12 ° C or higher and the minimum temperature at night to 8 ° C in the cultivation environment in winter, and the temperature is 30 in summer. If the temperature exceeds ℃, it is preferable to sufficiently ventilate the cultivation environment and put up a blackout curtain to suppress the temperature rise of the cultivation environment.

The place of cultivation may be artificially controlled so as to have the above-mentioned cultivation conditions. The cultivation process may be carried out in a facility such as a greenhouse, a tunnel or a greenhouse, or may be carried out in an outdoor environment, but it enables non-heading Brussels sprouts to be harvested at all times throughout the year. From the point of view, it may be more preferable to do it in the facility.

In the cultivation step, it is preferable to carry out a leaf scraping step to scrape the leaves hidden from the upper part of the plant when the plant height of the non-heading Brussels sprouts reaches, for example, 30 cm to 40 cm. Then, when the lateral buds of Brussels sprouts grow to a length of about 1 cm, the leaf scraping step may be continuously performed so that the number of true leaves per plant is maintained at 15 to 20. .. In the leaf scraping process, for example, one or two leaves are scraped once a week. Since the leaf-shaved true leaves can be shipped as commercial products (for example, for green juice and smoothies), the leaf-shaved true leaves are also harvested.

The true leaf to be scraped is the true leaf that holds the lateral bud (immediately below the lateral bud). FIG. 1 shows a state in which the upper true leaves of the main shaft of Brussels sprouts are left without scraping, and the lower true leaves are scraped. In this way, the true leaves are mainly attached to the main axis of Brussels sprouts, but when the lateral buds are elongated to form side branches, the true leaves also refer to the true leaves attached to the side branches. If the height of the non-heading Brussels sprouts is high, the non-heading Brussels sprouts may fall down. Therefore, it is preferable to attract the non-heading Brussels sprouts when the plant height reaches a predetermined height.

The period during which the cultivation process is carried out is not particularly limited as much as possible, but the harvesting of Brussels sprouts, which will be described later, may be continued for at least 7 months, 8 months or more, and 9 months or more. The upper limit of the period for carrying out the cultivation process is not particularly limited, but is, for example, 12 months or less.

(1) Side bud collection step In the above cultivation step, a side bud collection step may be performed in which the side buds (synonymous with armpit buds) of Brussels sprouts are removed. In the side bud collection step, the side buds (first generation side buds) attached to the main axis of Brussels sprouts are mainly removed, but the first generation side buds are not removed and are extended to the side branches as they are, and the side buds attached to the side branches (second generation side buds). The side buds of the generation) may be removed. The side buds of the second generation or later may be extended to the side branch as it is without removing the side buds (side buds of the third generation or later) attached to the side branch.

Removal of the lateral buds is a step necessary for stable generation of non-heading Brussels sprouts, which will be described later, but the removed lateral buds may be shipped as a commercial product.

Removal of lateral buds can be performed by separating the lateral buds from the stems (spindle and lateral branches) of Brussels sprouts. As for the lateral buds of Brussels sprouts, all the lateral buds that have grown to a size suitable for harvesting at the time of harvesting in one plant may be harvested, or a part of the lateral buds of a suitable size for harvesting (for example, 30%). More than 50%, more than 60%, more than 70%, more than 80%, more than 85%, or more than 90% and less than 100%) may be harvested. When harvesting a part of the lateral buds having a size suitable for harvesting in one plant, it is preferable to harvest in a spiral shape with respect to the stem. By further cultivating the lateral buds after harvesting, the stems are further elongated, and further lateral buds are grown from the elongated stems. Therefore, the lateral buds may be further harvested.

(2) Harvesting process of non-heading Brussels sprouts In the above cultivation process, when non-heading Brussels sprouts from which side buds have been removed are continuously cultivated, side buds are shown in FIGS. 1 (a) and 1 (b). It produces outer leaves (called non-heading Brussels sprouts) that extend from the cut end of the Brussels sprouts, a phenomenon that is not observed in soil cultivation of non-heading Brussels sprouts. This outer leaf (non-heading Brussels sprout tree) is also edible and has high commercial value. FIG. 1A is a diagram for explaining a cultivation method according to an embodiment of the present invention, and FIG. 1B is an enlarged view of an elongated portion of a non-heading Brussels sprout treef.

In one embodiment of the present invention, the outer leaves of Brussels sprouts can be harvested as non-heading Brussels sprouts, and many non-heading Brussels sprouts can be continuously harvested. This contributes not only to the stable supply of non-Brussels sprouts (lateral sprouts) but also to the stable supply of non-heading Brussels sprouts, and also to the spread of non-heading Brussels sprouts.

<Non-headed Brussels sprouts>
As used herein, the "non-heading Brussels sprout" is an outer leaf extending from a cut end of a non-heading Brussels sprout. As shown in FIG. 1, non-heading Brussels sprouts grow from hydroponically grown Brussels sprouts. 2 (a) and 2 (b) are diagrams for explaining non-heading Brussels sprouts cultivated in the cultivation method according to the embodiment of the present invention. In the non-heading Brussels sprouts, unlike the lateral buds (a form in which a plurality of leaves are attached to one extremely short axis), each leaf develops independently of each other (see (a) in FIG. 2). As will be described later, these leaves are harvested one by one (ie, by leaf harvesting).

<Outer leaf cultivation process>
In the outer leaf cultivation step, non-heading Brussels sprouts from which at least one of the above side buds has been removed in the side bud harvesting step are hydroponically cultivated. This causes the non-heading Brussels sprouts to grow from around the cut end of the lateral sprouts. Since the outer leaf cultivation process is a part of the above-mentioned cultivation process and the cultivation conditions and cultivation environment are the same, detailed description thereof will be omitted.

<Outer leaf harvesting process>
The outer leaf harvesting step is a part of the above-mentioned cultivation process, and the outer leaves extending from the periphery of the cut end of the lateral buds are used as non-heading brussels sprouts, for example, one by one and harvested. The non-heading Brussels sprouts may be those extending from the cut end of the first-generation lateral buds that first grew at the site of the stem (also called the main shaft or main branch) of the non-heading Brussels sprouts. The 1st generation side buds may be elongated as they are without being cut (become the 1st generation side branch), and the 2nd generation side buds attached to the side branch may be elongated from the cut end. Of course, non-heading is obtained from the side buds of the 2nd generation or later (nth generation: n is an integer of 2 or more) to obtain the nth generation side branch, and the n + 1 generation side bud attached to this side branch is cut out. Brussels sprouts may be elongated.

The non-heading Brussels sprouts harvested can be substantially round or approximately elliptical in width and length. The harvested non-heading Brussels sprouts are not elongated like the true leaves of non-heading Brussels sprouts seedlings (so-called baby leaf), so the shapes of non-heading Brussels sprouts and baby leaf of non-heading Brussels sprouts are. Can be easily distinguished from.

The non-heading Brussels sprouts to be harvested are preferably those having a leaf width of 3 cm or more and 6 cm or less and a length of 3 cm or more and 6 cm or less. As shown in FIG. 2B, the non-heading Brussels sprouts have, for example, a leaf width of 5 cm or more (L size), a leaf width of about 4 cm (M size), and a leaf width. You may harvest about 3 cm (S size) and each size.

Harvesting of non-heading Brussels sprouts can be carried out by separating the non-heading Brussels sprouts from the stems (spindle and side branches) of the non-heading Brussels sprouts. As for non-heading Brussels sprouts, all of the plants grown to a size suitable for harvesting at the time of harvesting may be harvested, or a part of those having a size suitable for harvesting (for example, 50% or more). 60% or more, 70% or more, 80% or more, 85% or more, or 90% or more and less than 100%) may be harvested. After harvesting the non-heading Brussels sprouts, the non-heading Brussels sprouts grow one after another by continuously cultivating them. It may be repeated until no leaves grow. When non-heading Brussels sprouts are harvested from around the cut end of the lateral buds, new non-heading Brussels sprouts are generated from around the same cut end. Therefore, in the outer leaf harvesting step, one or more of the cycles are set as one cycle in which one or more leaves are extended from around the cut end of the lateral buds that have been removed and the leaves are harvested one by one. Can be done once.

In addition, for the harvested non-heading Brussels sprouts, if necessary, cut off unnecessary parts (yellowed parts, damaged parts, etc.), or use a bag, packaging film, wrap, etc. , Non-heading Brussels sprouts may be packaged. The non-heading Brussels sprouts are preferably treated in this way (particularly packaging). The vegetable package containing the non-heading Brussels sprouts may be a package of a plurality of non-heading Brussels sprouts, but preferably 10 grams or more, 20 grams or more, 30 grams or more, 40 grams or more. , Or 50 grams or more of vegetables (which may be non-heading Brussels sprouts alone) may be preferably packaged. Vegetable packages containing non-heading Brussels sprouts are 500g or less, 400g or less, 300g or less, 200g or less, or 100g or less (non-heading Brussels sprouts alone) for home use. It may be preferable to package the product. In the case of commercial use, the vegetable package containing the non-heading Brussels sprouts may be packaged with kilograms of vegetables (the non-heading Brussels sprouts may be a single item). Vegetable packages containing non-heading Brussels sprouts can also be used for raw consumption such as salads, such as baby leaf.

The vegetable package containing non-heading Brussels sprouts may be a mixed leaf package in which the non-heading Brussels sprouts and the leaves of a plant different from the non-heading Brussels sprouts are packaged together. Other plant leaves to be packaged with non-heading Brussels sprouts include, for example, leafy vegetables such as lettuce, arugula, brassica, spinach, and baby leaf thereof. The packaged product of the mixed leaf is preferably for raw consumption such as salad. For example, the packaged product of mixed leaf contains non-heading Brussels sprouts of 1% or more, 5% or more, 10% or more, 15% or more, 20% or more, 25% or more, and 30% or more of the total content (weight). It is packaged. In other examples, the mixed leaf package contains non-heading Brussels sprouts within a range of 1% or more and 25% or less of the total content (weight). The proportion of non-heading Brussels sprouts is, for example, 1% or more and 5% or less of the total content (weight), 1% or more and 10% or less, and 5% or more and 15% or less. Alternatively, it can be in the range of 15% or more and 25% or less. By changing the proportion of Brussels sprouts cabbage tree, it is possible to provide a package of mixed leaves according to the desired taste and color.

[Cultivation kit]
The non-heading Brussels sprout cultivation kit according to an embodiment of the present invention includes seedlings of non-heading Brussels sprouts. In addition, the cultivation kit for Brussels sprouts may further include a cultivation bed for hydroponically cultivating the seedlings.

According to the non-heading Brussels sprout cultivation kit according to the embodiment of the present invention, it is possible to harvest more non-heading Brussels sprouts and non-heading Brussels sprouts more continuously. Since the seedlings and cultivation beds of non-heading Brussels sprouts included in the cultivation kit of Brussels sprouts are the same as the seedlings and cultivation beds in the method for cultivating non-heading Brussels sprouts according to the embodiment of the present invention described above. The detailed description thereof will be omitted. When the cultivation kit for Brussels sprouts has a cultivation bed, the seedlings of Brussels sprouts and the cultivation bed may be included as separate bodies, or may be included with the seedlings planted on the cultivation bed. May be good.

The cultivation kit for Brussels sprouts may further include a culture solution to be given to the seedlings. The culture solution included in the cultivation kit for Brussels sprouts may be an inorganic culture solution or an organic culture solution, and the culture solution in the method for cultivating Brussels sprouts according to the above-described embodiment of the present invention. Since it is the same as the above, the detailed description thereof will be omitted.

The cultivation kit for Brussels sprouts may include an attracting means for preventing the Brussels sprouts from collapsing. The type of attracting means is not particularly limited, and examples thereof include a string (pulling the stem of Brussels sprouts from above the cultivation facility). According to the cultivation method according to the embodiment of the present invention, the plant height of Brussels sprouts is very high and the risk of falling is higher because the cultivation can be carried out for a longer period of time as compared with soil cultivation.

The cultivation kit for Brussels sprouts may further include a cultivation manual that describes a method for cultivating Brussels sprouts according to an embodiment of the present invention. In addition, the cultivation kit for Brussels sprouts may further include other components necessary for cultivation of Brussels sprouts, such as pesticides.

[Example 1]
(Seedling raising process)
Culture Mat Clean (manufactured by Nippon Rockwool Co., Ltd.) was set in a nursery box with a hole in the bottom and initially irrigated with tap water. One seed of Minivale No. 6 was dropped and sown in each hole provided in the irrigated culture mat clean.

This seedling raising box was placed in a vinyl house, and germination was carried out while appropriately irrigating while controlling the temperature inside the vinyl house. After germination, use OAT House Fertilizer A formulation (manufactured by OAT Agrio Co., Ltd.) with pH 5.5 to 6.5 and EC 0.8 to 1.2 as a culture solution and appropriately irrigate the leaves to about 3 true leaves. I raised seedlings until it became.

(Secondary seedling raising process)
When the number of true leaves reached about 3, the culture mat clean was cut off along the cut and divided, and each plant was transplanted into a 75 × 100 × 100 pot. The pot was used after the culture solution was saturated with water before transplanting the strain. Secondary seedlings were raised until the number of true leaves after transplanting reached 8 to 10. During the secondary seedling raising, the water content of the pot is controlled to 50 to 80% (weight: 360 to 570 g) using the above culture solution, and the pot is irrigated at least once a day, and the culture solution concentration does not change suddenly. I did. At high temperatures, the temperature was lowered by increasing the amount of irrigation of the culture solution and the number of irrigations.

(Planting process)
When the number of true leaves reached 8 to 10, the seedlings were planted in a rock wool bed and cultivated in rock wool (RW cultivation). Before planting, the rock wool bed used as a cultivation bed was saturated with the above-mentioned culture solution. Six seedlings were planted separately in rock wool at intervals of 30 cm. After planting, the water content of the cultivation bed was controlled to be high to promote the survival of seedlings. The amount of irrigation after planting was set at 1.2 L / strain from October to March and 2.8 L / strain from March to September per day. When the seedlings grew, the stems collapsed due to their own weight, so I attracted them.

When the plant height reached 30-40 cm, the overlapping leaves were scraped when the plant was viewed from above. When the lateral buds grew to about 1 cm, the number of true leaves was controlled to be 15 to 20, and 1 to 2 true leaves were scraped once a week.

(Harvest process)
The grown lateral buds were harvested spirally with respect to the stem. Cultivation was continued even after the lateral buds were cut, and as shown in FIG. 2 (a), non-heading Brussels sprouts (petit veil leaves) extending from the cut end of the harvested Brussels sprouts were harvested. Petit veil reefs were harvested 30 times in a row from March to November 2018. Table 1 shows a graph showing the yield at each harvest. For convenience of explanation, Table 1 does not show all the data at the time of harvest, but shows only a part. As shown in Table 1, the petit veil leaf could be stably harvested for 7 months or longer.

[Example 2]
RW cultivation, NFT cultivation, and DFT using the seeds of Mini Veil No. 6, Petit Veil Rouge (trade name of Masuda Seed Co., Ltd.) and Petit Veil White (trade name of Masuda Seed Co., Ltd.) Cultivated. The RW cultivation conditions were the same as in Example 1.

In NFT and DFT cultivation, Minivale No. 6 seedlings were transplanted into planting panels at intervals (30-60 cm) according to conventional methods. In NFT cultivation, a planting panel is installed on a hydroponic cultivation bed with a gradient of 1/80 to 1/100, and the roots of seedlings are immersed in a shallow culture solution flowing by the gradient of the hydroponic cultivation bed to spread the culture solution. Always circulated. In DFT cultivation, the planting panel was floated on a pool containing the culture solution, and the roots of the seedlings were immersed in the culture solution at a deep water depth.

In NFT cultivation and DFT cultivation, 375 g of Otsuka House No. 1 and 250 g of Otsuka House No. 2 were dissolved in 500 L of water as a culture solution. The EC of the culture broth was about 1.2 and the pH was 6-7. The culture broth decreased during cultivation was added as appropriate, and the culture broth was replaced when the EC changed drastically. In the early stage of cultivation, the leaves were not scraped, and when the plants became crowded, the number of true leaves was managed to be 15 to 20 and the leaves were scraped. The grown seedlings were attracted so that the stems would not fall.

The grown lateral buds were harvested spirally with respect to the stem. In addition, cultivation was continued even after the side buds were cut off, and petit veil leaves extending from around the cut end of the side buds were harvested. The harvesting conditions for the petit veil leaves were that the leaves of the side buds were harvested one by one and had frills. The results are shown in Table 2.

Numbers 1, 4 and 5 indicate the weight of the petit veil leaf harvested from RW cultivated mini veil No. 6. Number 2 indicates the weight of petit veil leaf harvested from RW cultivated petit veil white. Number 3 indicates the weight of Petit Vert Leaf harvested from RW-cultivated Petit Vert Rouge. Number 6 indicates the weight of the petit veil leaf harvested from NFT cultivated mini veil No. 6. Number 7 indicates the weight of Petit Veil Leaf harvested from DFT cultivated Mini Veil No. 6.

For numbers 1 to 3, the seedlings were transplanted on 9/8 and planted on 10/5. For No. 4, the seedlings were transplanted on 8/1 and planted on 8/31. Number 5 was transplanted on 10/12. Numbers 6 and 7 planted seedlings on 9/8. Numbers 1, 4 to 7 are the results of cultivating 10 strains, and numbers 2 and 3 are the results of cultivating 5 strains, respectively.

In Table 2, those having a petite veil leaf length of 5 cm or more were defined as L size, those having a length of 4 cm or more and less than 5 cm were defined as M size, and those having a length of less than 4 cm were defined as nonstandard. As shown in Table 2, many petit veil leaves could be harvested even in hydroponics other than RW cultivation and even if the varieties were different.

The present invention can be used in the agricultural field particularly relating to the cultivation of non-heading Brussels sprouts obtained by crossing Brussels sprouts and kale.
