Description

[Technical field]

[0001] The present invention relates to a method for cultivating Moss Phlox, in which shoots consisting of stems and leaves but no roots are grown into seedlings in a seedbed, and the method for cultivating Moss Phlox. Use This article relates to the cultivation method of Moss Phlox. [Background technology]

[0002] In recent years, planting large numbers of Moss Phlox over large areas of land has become common in parks and other areas for the purpose of improving the scenery for tourism, and on river banks, rice ridges, and slopes for the purpose of protecting the topsoil.

[0003] Incidentally, when planting Moss Phlox, as mentioned above, the plant is not fertilized by its own pollen, i.e., it has strong self-incompatibility, making it difficult for seeds to be produced, and even if seeds are produced, they are difficult to germinate. Therefore, it is common to first plant seedlings that have already grown to a certain size in flower beds in parks and other locations where they will be planted.

[0004] For the planting, in order to facilitate the rooting and transportation, the seedlings themselves separated from grown Moss Phlox plants, or shoots consisting of only stems and leaves, are planted in multiples in 10-inch pots or cell trays consisting of finely divided cells together with culture soil, and the roots bite into the culture soil and intertwine to take the shape of the pot or cell; potted seedlings or cell seedlings (hereinafter referred to as "pot seedlings, etc.") are used, propagated vegetatively so as to form a so-called root ball.

[0005] However, Moss Phlox grows very slowly, and even fully grown Moss Phlox has a short height, so it is weak in competing with weeds during the growth process. Therefore, it is important to carry out weed control to eliminate the weeds that grow around the Moss Phlox throughout the entire cultivation period, but there is a problem in that the management effort and expense required for this is enormous. Therefore, for example, potted seedlings are densely planted to eliminate gaps between seedlings that may cause weeds to grow. However, if the land area in which the potted seedlings are to be planted is large, the number of potted seedlings corresponding to the land area to be planted becomes huge, which causes high costs and also causes the planting work itself to be very large. Furthermore, if pot seedlings are cultivated by oneself, it takes 4 to 6 months for the pot seedlings to grow, and the labor and expense of water management and other management work during that time is enormous. In addition, if pot seedlings are purchased from outside, it is necessary to purchase a large number of pot seedlings, which causes problems such as huge purchasing costs and unclear disease and pest control measures at the place where the pot seedlings are purchased. In other words, if stem nematode disease, especially caused by the nematode Nematode, is brought in through the purchased pot seedlings, it is a difficult-to-control infectious disease and there is a risk that it will spread to the surrounding Moss Phlox and cause the entire planted area to wither and die, and since the pathogenic nematode remains in the soil, even if new Moss Phlox is planted, it will also be infected, so there is a risk of huge damage, such as the need for soil disinfection and soil-dressing work in order to plant Moss Phlox in the planted area.

[0006] In addition, in order to suppress the overgrowth of weeds, a method is also used in which the planting area is covered with a weed control sheet, and then planting holes of about 10 cm in diameter in the weed control sheet, which corresponds to the outer diameter of a normally used three-inch pot, are opened in the weed control sheet, and potted seedlings, etc. are planted through the planting holes. However, there is a problem in that gaps are formed between the planted potted seedlings, etc. and the planting holes opened in the weed control sheet, and weeds can grow through the gaps. but there were.

[0007] Thus, one method has been devised in which a sheet-like weed-control substrate is laid over the construction surface where planting will take place, and an inverted cone-shaped planting pot with an open bottom and containing the desired plant, such as Moss Phlox, is inserted so as to pierce the weed-control substrate from the apex side (see Patent Document 1); another method is where mulch with weed suppression effect is applied to the construction surface, and the mulch is cut into an inverted T shape, holes are opened, and cell seedlings are planted (see Non-Patent Document 1).

[0008] However, when a planting pot having an inverted cone shape with an open bottom and containing a plant such as Moss Phlox is inserted from the apex side into the weed-control substrate laid on the application surface, there is almost no gap between the weed-control substrate on the application surface and the planting pot inserted into the weed-control substrate, so although the overgrowth of weeds from the application surface can be reliably suppressed, the inserted planting pot itself has an open top, so the overgrowth of weeds above the planting pot cannot be suppressed, resulting in the problem that extra management work such as weeding is required.

[0009] Furthermore, when the mulch covering the construction surface is cut into an inverted T shape to open holes and then cell seedlings are planted, large holes are created in the mulch covering the construction surface, making it impossible to suppress the overgrowth of weeds, and there is a problem that a great deal of maintenance work such as weeding is required.

[0011] [Non-Patent Document 1] Hiroshima Prefectural Technology Research Institute Agricultural Technology Center Research Report / September 2007 Summary of the Invention [Problem to be solved by the invention]

[0012] Therefore, the present invention is directed to cultivating Moss Phlox by reliably suppressing the overgrowth of weeds during the seedling raising stage, when shoots grow into seedlings, while enabling the raising of as many shoots as possible for a given seedbed area, shortening the seedling raising period, and reducing the burden of management work such as weeding, and by reliably suppressing the overgrowth of weeds during the planting stage, when seedlings that have grown to a certain extent are allowed to grow further, thereby reducing the burden of management work such as weeding. [Means for solving the problem]

[0013] The first feature is, During the seedling stage, when the Moss Phlox grows from shoot to seedling, (a) Installing weed-control sheets on seedbeds, (b) forming a plurality of linear slits in the stretched weed control sheet; (C) A plurality of shoots are planted linearly along each of the plurality of slits formed in the weed-control sheet in a seedbed.

[0014] For this reason, a weed control sheet is stretched over the seedbed, multiple linear slits are formed in the weed control sheet, and multiple shoots are planted in a straight line through each slit, so that the slits formed in the weed control sheet communicate with the seedbed with a minimum of gaps and are deformable, and even if a shoot is inserted into the slit, the shoot is planted in a straight line along the slit, so the slit only opens to the extent of the cross section of the shoot, which is thin, so the slits and the shoots fit tightly together and the overgrowth of weeds can be suppressed. At this time, if the weed control sheet is elastic, the slits will close due to the elasticity of the weed control sheet, so they will fit tightly against the surface of the shoots and the gaps in the slits will become smaller, making it possible to more reliably suppress the overgrowth of weeds. Furthermore, by planting multiple shoots in one slit formed in the weed control sheet, the number of shoots that can be planted per seedbed area can be increased, enabling efficient seedling cultivation.

[0015] When each shoot grows and takes root, the roots grow in a direction where there are no obstacles, so they do not become entangled with each other, and the culture soil that forms the seedling bed hardly adheres to them, so the roots do not bite into the culture soil and become entangled to form a root ball. Therefore, the seedling raising period can be shortened while reducing the seedling raising work. Moreover, after multiple shoots planted in one slit grow and take root to become seedlings, even if the roots of the seedlings are somewhat entangled, they do not form a root ball, so they can be easily separated into individual seedlings, and the workload for the planting work, which is the next work after this seedling raising work, is not increased.

[0016] The second feature is, During the seedling stage, when the Moss Phlox grows from shoot to seedling, (a) Installing weed-control sheets on seedbeds, (b) forming a plurality of linear slits in the stretched weed control sheet; (c) forming recesses in the seedbed parallel to the slits through each of the multiple slits formed in the weed control sheet; (D) Inserting a plurality of shoots linearly along the recesses provided in the seedbed into each slit formed in the weed-control sheet; (e) Planting the weeds by piling up soil around the base of a shoot inserted into a recess in the seedbed within the weed control sheet laid out on the seedbed; (F) The above operations (C), (D) and (E) are carried out for all of the multiple slits formed in the weed control sheet laid out on the seedbed, Furthermore, the third characteristic is, The recess provided in the seedbed is a hole or a groove.

[0017] Therefore, by providing a recess, such as a hole or a groove, in advance in the seedbed below the slit, the work of planting shoots in the seedbed can be simplified. If the recess provided in the seedbed is a hole, the shoots can be planted in the seedbed at an accurate interval through the slit, and if it is a groove, even if the position of the shoot shifts when planting it in the seedbed, the position of the shoot can be corrected and the shoot can be planted in the correct position in the seedbed.

[0018] Furthermore, 4 The characteristics of the above First feature ~ The third feature A seedling grown by any one of the methods for growing Moss Phlox seedlings described above, As shown below A method for cultivating Moss Phlox used in planting Moss Phlox, comprising the steps of: In planting the Moss Phlox, (a) Installing weed-control sheets in planted areas, (b) forming a plurality of T-shaped or cross-shaped slits in the stretched weed-control sheet so that a single Moss Phlox seedling or a bundle of Moss Phlox seedlings each containing two to five seedlings can be inserted into the weed-control sheet; (c) Insert a single Moss Phlox seedling or a bundle of Moss Phlox seedlings into each intersection of the multiple slits formed in the weed control sheet and plant it in a planting area. It is something the law of nature , Also, Fifth feature As, the above First feature ~ The third feature A seedling grown by any one of the methods for growing Moss Phlox seedlings described above, As shown below A method for cultivating Moss Phlox used in planting Moss Phlox, comprising the steps of: In planting the Moss Phlox, (a) Installing weed-control sheets in planted areas, (b) forming a plurality of T-shaped or cross-shaped slits in the stretched weed-control sheet so that a single Moss Phlox seedling or a bundle of two to five Moss Phlox seedlings can be inserted; (c) inserting a rod-shaped object through the intersections of a plurality of slits formed in the weed-control sheet to make planting holes in the planting area; (D) Inserting a single Moss Phlox seedling or a bundle of two to five Moss Phlox seedlings into a planting hole drilled in a planting area through each slit formed in the weed control sheet; (e) Planting the seedlings by piling up soil around the base of the seedlings inserted into the planting holes in the weed-control sheet stretched over the planting area; (f) The above operations (c), (d) and (e) are carried out for all of the multiple slits formed in the weed control sheet stretched over the planting area. .

[0019] Therefore, The fourth and fifth featuresAs described above, after the multiple shoots planted in one slit grow and take root to become seedlings, even if the roots of the seedlings are somewhat entangled, they do not form a root ball, so they can be easily separated into individual seedlings, and the workload for planting is not increased. Naturally, by providing T-shaped or cross-shaped slits in the weed control sheet stretched over the planting area, the opening is the smallest, the roots of the seedlings are not damaged during planting, and since a single Moss Phlox seedling or a bundle of Moss Phlox seedlings consisting of two to five seedlings is inserted into the intersection, the seedlings can be easily inserted into the position to be planted, and the workload for planting can be reduced. The slit into which the seedlings are inserted is in close contact with the seedlings, so the gap at the slit is minimized, and the overgrowth of weeds in the planting area can be reliably suppressed. Furthermore, if planting holes are provided in advance at the intersections of the T-shaped or cross-shaped slits, the workload for planting the seedlings can be further reduced.

[0020] And especially , The fourth feature is, If only one Moss Phlox seedling is inserted through the intersection of the slits, and that one Moss Phlox seedling is missing in the planting area, it may become necessary to repair the missing part by planting another Moss Phlox at a later date, rather than trying to make the planting area bloom like a carpet of Moss Phlox. On the other hand, however, in the planting area, the slit into which the seedling is inserted is firmly attached to the seedling, so the gap with the slit is minimized, and the overgrowth of weeds in the slit can be reliably suppressed. Furthermore, if there is only one seedling, there will be no other seedlings to plant in the same slit, so the growth of the Moss Phlox is promoted, the roots in the planting area become stronger, and it can be planted reliably in the planting area. Furthermore, if multiple Moss Phlox seedlings, i.e., two to five seedlings, are inserted through the intersections of the slits and planted as a seedling bundle, the presence of the other seedlings inserted at the same time makes it difficult for each seedling to grow thicker after it has grown, but even if one seedling is missing, the other seedlings in the bundle will grow, so that when attempting to have a carpet of Moss Phlox covering the planting area, it is not necessary to repair the missing seedling by planting another Moss Phlox. And even if a gap forms between the bundle of seedlings and the slits, the leaves of each bundle of seedlings reliably close the gap in the slit and provide a shading effect, thereby suppressing the overgrowth of weeds. However, if the number of seedlings in a bundle is six or more, the number of Moss Phlox seedlings required for a certain area of ​​planting land becomes very large, and the economic efficiency of Moss Phlox seedlings, which are expensive per seedling, decreases. Moreover, the seedlings are planted too densely at the intersection of one slit, increasing the risk of poor growth of each seedling in one bundle, and as in the case of a missing sapling, it becomes necessary to repair the poorly grown area at a later date by planting another Moss Phlox. Therefore, when planting Moss Phlox seedlings in a bundle, the appropriate number is two to five.

[0021] Regarding the size of the slits in the weed-control sheet that is stretched over the planting area, it is appropriate for the length of one side to be between 1 cm and 3 cm. That is, if the length of one side of the slit is less than 1 cm, it is difficult to insert the seedlings or the bundle of seedlings, and when piling up soil around the roots of the inserted seedlings, fingers or tools cannot be moved freely within the slit, resulting in insufficient piling up of soil and the risk of damaging the seedlings to be planted with fingers or tools, resulting in missing stalks. Also, if the length of one side of the slit is more than 3 cm, the slit is likely to roll up even after the seedlings or the bundle of seedlings are planted in the planting area, and gaps are created there, making it impossible to suppress the growth of weeds.

[0022] Furthermore, The fifth feature is,By forming planting holes in the soil below the intersections of the T-shaped or cross-shaped slits in advance, the burden of planting seedlings can be further reduced. Effect of the Invention

[0023] The present invention relates to a cultivation method for Moss Phlox in which seedlings are grown from shoots inserted into a seedbed, then transplanted into a permanent planting site, and grown in the permanent planting site, in which the surfaces of the seedbed and the permanent planting site are covered with a weed-control sheet, and slits are formed in the weed-control sheet through which a plurality of shoots are planted in a straight line in the seedbed, and a single seedling or a bundle of Moss Phlox seedlings consisting of two to five seedlings are planted in the permanent planting site.Since the slits formed in the weed-control sheet only form very narrow gaps and can be deformed, the shoots or seedlings are securely held in close contact with the slits, and the surfaces of the seedbed and the permanent planting site are not unnecessarily exposed to the outside, thereby providing the excellent effect of reliably suppressing the overgrowth of weeds in the seedbed and the permanent planting site.

[0024] Furthermore, a work tool such as a scraper or plastic stake can be inserted through slits formed in the weed-control sheet stretched over the surface of the seedbed and planting area to create recesses such as holes or trenches in the seedbed, and planting holes can be drilled in the planting area. After shoots or seedlings are inserted into the holes, trenches or planting holes, soil can be piled up, and the surface of the seedbed and planting area can be sealed with the weed-control sheet, thereby reducing the burden of planting or planting the shoots or seedlings, and also facilitating subsequent maintenance work, thereby providing the excellent effect of reducing the burden.

[0025] In particular, multiple shoots can be planted in each slit formed in the weed-control sheet covering the seedbed, which increases the number of shoots that can be cultivated per seedbed area and makes seedling raising more efficient. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] In a method for cultivating Moss Phlox, a plurality of shoots are arranged in a straight line and grown in a seedbed covered with a weed-control sheet, and seedlings that have grown to a certain extent are bundled together (one or two to five seedlings) and planted in the planting position through slits formed in the weed-control sheet laid out in the planting area. EXAMPLES

[0028] Figures 1 to 10 show a schematic diagram of a Moss Phlox cultivation method according to the present invention, which comprises a Moss Phlox seedling raising method in which shoots 4 are grown into seedlings 5 ​​after a certain degree of growth as shown diagrammatically in Figures 1 to 4, and a Moss Phlox planting method in which the seedlings 5 ​​after a certain degree of growth are planted in a planting site as shown diagrammatically in Figures 5 to 10. The Moss Phlox seedling raising method and the Moss Phlox planting method will be described below.

[0029] First, the method for raising Moss Phlox seedlings at the seedling raising stage in which the shoots 4 are grown into seedlings 5, as shown in Figs. 1 to 4, is as follows. In the cultivation method of Moss Phlox, in the seedling raising stage where the shoot 4 is grown into a seedling 5, First, a highly rigid weed-control sheet 2 made of polypropylene is stretched over the surface of the seedbed 1 in which the shoots 4 are planted, to suppress the overgrowth of weeds and the like. As a result, the entire surface of the seedbed 1 is sealed and covered with the weed-control sheet 2, so that the overgrowth of weeds in the seedbed 1 can be reliably suppressed. Secondly, multiple linear slits 3 of about 10 cm are formed at intervals of about 5 cm on the entire weed control sheet 2 stretched over the surface of the seedbed 1 to prevent slack between the slits 3 (see Fig. 1). When planting a certain number of shoots 4 in the seedbed 1, if the intervals between the slits 3 are too wide, it is uneconomical because a large area is required for the seedbed 1, and if the intervals are too narrow, the weed control sheet 2 itself will slacken and the weed control sheet 4 will not be able to adhere securely to the seedbed 1, and a gap will be created between the slit 3 and the shoot 4 inserted therein, reducing the effect of suppressing the overgrowth of weeds. In particular, in adjacent slits 3, 3 with the same tear direction, if the tear direction of the slit 3 expands when a shoot 4 is inserted into one slit 3, it may connect with the other adjacent slit 3. In this case, even if multiple shoots 4 are inserted between the connected slits 3, 3, unnecessary gaps will be created, reducing the effect of suppressing the overgrowth of weeds. Therefore, the optimum distance between the slits 3 is about 5 cm. In addition, as for the length of each slit 3 itself, if the length of the slit 3 is increased, there is a problem that the adhesion between the chute 4 and the end face of the slit 3 becomes poor when the chute 4 is inserted, so the optimum length of each slit is about 8 cm to 12 cm. Thirdly, a scraper is inserted into the soil through the slits 3 formed across the entire weed control sheet 2 stretched over the surface of the seedbed 1, and an insertion groove 1a 5 cm deep required to hold the shoot 4 firmly is provided in the culture soil of the seedbed 1, parallel to the slits 3. At this time, the slits 3 have a gap large enough to insert the scraper, so the slits 3 do not interfere with the operation of the scraper, and the insertion groove 1a can be provided accurately. Fourthly, six shoots 4 are inserted linearly into the insertion groove 1a arranged in the seedbed 1 through the slits 3 formed in the weed control sheet 2 stretched over the surface of the seedbed 1. In this embodiment, six shoots 4 are inserted, but since the length of one slit 3 is optimally about 8 cm to 12 cm as described above, the number of shoots 4 to be inserted is also determined based on the length of the slit 3. That is, if a large number of shoots 4 are inserted into one slit 3, the number of shoots grown per given area of ​​the seedbed 1 can be increased, but the shoots 4 will be too close together, hindering their smooth growth. Therefore, the shoots 4 inserted into the slits 3 also need to be spaced apart to some extent for smooth growth, and therefore, considering the length of the slit 3, the appropriate number of shoots 4 to be inserted into one slit 3 is 6 to 10. Furthermore, even when the shoots 4 grow into seedlings 5 ​​during the seedling raising stage, the slits 3 in the weed-control sheet 2 deform and no unnecessary gaps are formed between the shoots 4 or between the grown seedlings 5, so that overgrowth of weeds can be reliably suppressed. By inserting the shoots 4 through the slits 3 formed in the weed control sheet 2, even if the insertion position of the shoot 4 is misaligned, the shoot 4 can be slid along the insertion groove 1a to be inserted into the correct position of the insertion groove 1a, so that the shoots can be easily and reliably planted in the seedbed 1. When planting the shoots 4 in the seedbed 1 through one slit 3, by evenly arranging multiple shoots 4 in the slit 3, the whorled leaves of the shoots 4 cover and shade the gaps that are generated when the shoots 4 are planted through the slits 3, thereby eliminating room for weeds to grow (see Figures 3 and 4). Fifthly, in the weed control sheet 2 stretched over the seedbed 1, the roots of the shoots 4 inserted into the insertion grooves 1a arranged in the seedbed 1 are planted in the seedbed 1 by pressing down the soil from the surface of the weed control sheet 2 with hands or the like. Note that instead of pressing down the soil by hands or the like, Metal spatulaEven if a soil-piling tool such as a piling tool is inserted diagonally through the slits 3, there is a gap in the slits 3 for inserting the soil-piling tool, so the soil can be easily and reliably pushed up to the base of the chute 4 and the operation of the soil-piling tool is not impeded. Moreover, even when the soil is piled up, the slits 3 in the weed control sheet 2 have only a minimum gap, so the slits 3 formed in the weed control sheet 2 and the chutes 4 are reliably in close contact, and the overgrowth of weeds through the slits 3 formed in the weed control sheet 2 can be reliably suppressed. Sixthly, the third, fourth and fifth operations are carried out for all of the slits 3 formed in the weed control sheet 2 (see FIG. 2).

[0030] As shown in Figure 2, shoots 4 are planted through slits 3 in a weed-control sheet 2 that is provided over the entire seedbed 1, and during the seedling raising stage of the shoots 4 planted in the seedbed 1, watering is performed about once every 2 to 3 days to prevent the soil from drying out for 2 weeks to 1 month until roots 5a sprout from the shoots 4 and become established, and water management can be omitted for the following 1 to 3 months. Therefore, the weed-control sheet 2 covering the seedbed 1 suppresses the growth of weeds and reduces the management work at the seedling raising stage. The seedling raising period may be six months as in the past, but since the roots 5a of the seedlings 5 ​​do not form a root ball and can grow freely, the roots 5a will be sufficient to develop even in a seedling raising period of about two to four months, so the seedling raising period can be reliably shortened.

[0031] Next, the method of planting the Moss Phlox seedlings 5 ​​in the planting ground, which is shown in Figs. 5 to 10, is as follows. In the cultivation method of Moss Phlox, in order to plant a seedling 5 that has rooted from a shoot 4 and grown to a certain extent in a flower bed 6 as a permanent planting site, First, a highly rigid polypropylene weed-control sheet 2', which is also used at the seedling raising stage, is stretched over the surface of the flower bed 6 into which the seedlings 5 ​​grown to a certain extent by the above-mentioned Moss Phlox seedling raising method are planted. As a result, the entire surface of the flower bed 6 is sealed and covered with the weed-control sheet 2', which reliably suppresses the overgrowth of weeds. Secondly, a plurality of T-shaped slits 3' consisting of linear slits are formed at regular intervals in the weed control sheet 2' stretched over the entire surface of the flower bed 6 (see FIG. 5). The length of each side of the T-shaped slit 3' formed in the weed control sheet 2' is set to 1 cm to 3 cm so that when a single seedling 5 is planted through the slit 3', the slit 3' will be in close contact with the base of the seedling 5. If only one seedling 5 is to be planted, it is more appropriate to set each side of the slit 3' to 1 to 2 cm (however, conversely, when a bundle 5' of five Moss Phlox seedlings 5 ​​is planted, it is more appropriate to set each side of the slit to be close to 3 cm). The interval between the T-shaped slits 3' is appropriate to be 15 to 30 cm so that the grown Moss Phlox will cover the entire flower bed 6 evenly. Furthermore, by making the slits 3' T-shaped, the weed-control sheet 2' can be expanded by the slits 3', so that when the seedlings 5 ​​are planted in the flower bed 6, damage to the roots 5a of the seedlings 5 ​​caused by the expansion of the weed-control sheet 2' can be prevented. In this embodiment, the shape of the slit 3' is an exact T-shape, but the shape of the slit 3' does not have to be an exact T-shape as long as it can be expanded without damaging the roots 5a of the seedlings 5 ​​when planting. This is also true when the shape of the slit 3' is a cross shape. Thirdly, through each T-shaped slit 3' formed in the weed control sheet 2' stretched over the surface of the flower bed 6, planting holes 6a with a depth of 10 cm required for holding the seedlings 5 ​​or seedling bundles 5' in the flower bed 6 are drilled with a plastic stake from the intersection of each side forming the slit 3'. At this time, since the slit 3' is T-shaped and the intersection can be easily deformed, the movement of the plastic stake is not hindered and the planting holes 6a can be drilled accurately (see Figure 6). Fourthly, the seedlings 5 ​​are inserted one by one into the planting holes 6a drilled in the flower bed 6 using fingers or a plastic stake through a T-shaped slit 3' formed in the weed control sheet 2' stretched over the surface of the flower bed 6. By inserting the seedlings 5 ​​into the planting holes 6a through the T-shaped slits 3' formed in the weed control sheet 2', the seedlings 5 ​​are accurately inserted into the planting holes 6a drilled in the flower bed 6, and the seedlings 5 ​​can be planted in the flower bed 6 simply and reliably (see Figure 7). Incidentally, when the Moss Phlox seedlings 5 ​​to be planted in the planting area are planted as a seedling bundle 5' consisting of two to five seedlings, the seedling bundle 5' is arranged as shown in Figures 9(b) to (e) if the slit 3' is T-shaped, or as shown in Figures 10(b) to (e) if the slit 3' is cross-shaped, so that the gap between the seedling bundle 5' and the slit 3' is minimized when the seedling bundle 5' is inserted into the T-shaped or cross-shaped slit 3' formed in the weed control sheet 2' stretched over the planting area. Moreover, since multiple Moss Phlox seedlings 5 ​​are integrated into the seedling bundle 5', the planting work, such as inserting the seedlings into the slit 3' and piling up soil on the seedling bundle 5', can be handled in the same way as in the case of a single seedling 5. Furthermore, unlike potted seedlings, the roots 5a of the seedlings 5 ​​grown from the shoots 4 in the seedbed 1 do not become entangled with each other to form a root ball. Therefore, at the stage where the shoots 4 planted in a straight line in one of the slits 3 of the weed control sheet 2 stretched over the seedbed 1 have grown into seedlings 5, even if the series of seedlings 5 ​​appears to be in a bundle, the series of seedlings 5 ​​can be easily separated one by one, and the task of planting the seedlings 5 ​​in the flowerbed 6 is not burdensome. Fifthly, in the weed-control sheet 2' stretched at the time of planting, a metal spatula, which is a tool for piling up soil, is inserted obliquely through the T-shaped slit 3' and then turned vertically around the base of the seedling 5 inserted in the planting hole 6a drilled in the flower bed 6, to pile up soil. Therefore, by inserting the metal spatula for piling up soil through the T-shaped slit 3', the slit 3' is easily deformed because of its T-shape, so the movement of the metal spatula is not hindered, and soil piling can be performed easily and reliably. Moreover, even after the soil piling up is performed, the T-shaped slit 3' of the weed-control sheet 2' returns to its original state, so the T-shaped slit 3' formed in the weed-control sheet 2' and the seedling 5 are reliably in close contact with each other, and the weed-control sheet 2' stretched over the flower bed 6 can reliably suppress the overgrowth of weeds. Sixth, the above third, fourth and fifth operations are carried out in all of the T-shaped slits 3' formed in the weed control sheet 2'. As described above, the seedlings 5 ​​are planted throughout the flower bed 6 (see Figure 8). The seedlings 5 ​​planted in the flower bed 6 are watered about once every 2-3 days to prevent the soil from drying out for two weeks until the roots of the seedlings 5 ​​take root. Once the seedlings 5 ​​are established, watering is no longer necessary, so that the overgrowth of weeds can be reliably suppressed even at the planting stage, and the management work can be reduced.

[0032] As described above, by consistently carrying out the above-mentioned seedling raising method in the seedling raising stage in which shoots 4 grow into seedlings 5, and then planting the seedlings 5 ​​that have grown to a certain extent in a permanent planting site, the method reliably suppresses the overgrowth of weeds not only in the seedbed but also in the flower bed where the seedlings are planted, reduces the burden of the overall management work including weeding, and also ensures thorough sanitary management against diseases and insects. [Industrial Applicability]

[0033] The present invention can be applied to wide areas of land, such as parks, river banks, ridges, or slopes, in order to plant greening plants while suppressing the growth of weeds. [Explanation of symbols]
