Description

  INDUSTRIAL APPLICABILITY The present invention is one of the ground cover plants used for environmental greening, and a method for efficiently mass-producing the seeds of the genus Rhinoceros and Yablanc, which has been particularly evaluated in recent years, and the greening using the method It relates to the construction method.

  At present, land cover greening is generally performed by spraying Zhang turf or Western turf. Representative of the ground cover plants used for such greening are wild grass turfgrass such as wild buckwheat, koraishiba and bermudagrass (Tiftonshiba), and bentgrass as cold grass turfgrass (winter turf). Other ground cover plants such as grasses, bluegrass, fescues, ryegrass, etc. are mainly used as ground cover herbs, dwarf shrubs, vines and the like.

  These ground cover plants range from A to D in terms of management intensity as seen from the number of trimmings, and when additional cultivation management such as weeding and fertilization is added, the annual maintenance cost is 4,000 yen per square meter (A class) It is ~ 500 yen (D class), which is expensive. Reasons for this include cutting management (several to 150 times a year), fertilization, root removal, manual work, grass collection, loading, carrying out disposal, and sometimes disinfection / insecticing to prevent plant damage or landscape deterioration In the midst of labor shortages and high unit prices, man-made management must be carried out. In addition, root disposal and cutting of grass are difficult to incinerate locally from the environmental point of view. Because.

  In addition, there is a danger of the above-mentioned ground cover work, for example, lawn curing work on the embankment can be a hot work, work in an unreasonable posture on the slope, the risk of heat stroke, falling, sliding down, etc. It has been pointed out that there are many issues that need improvement in construction and maintenance management that depend on human power.

  In addition, the current general land cover planting requires a huge amount of money for its construction and subsequent management. Under the direct control of the Ministry of Land, Infrastructure, Transport and Tourism and the River Bureau, annual river levee mowing and lawn mowing costs 19.9 billion yen each year. We have ordered maintenance work. In addition, the situation is the same in each prefecture and each municipality. Considering spending reductions, reductions in public works, and reductions in annual maintenance costs, there is a need for a method that allows construction at low cost and requires little maintenance costs. However, it is difficult to innovate only the maintenance management technology in the current situation of the greening work by the existing ground cover plants, and it is desired to change the ground cover plant varieties themselves.

  Therefore, in recent years, interest in Ryu no beard and Yablanc has increased as ground cover plants. The characteristics of the Ryu no beard and Yablan are fertile and do not require the trouble of pruning, etc. and have good rooting, so they are excellent in greening, helping to prevent the growth of high stem weeds, prevent fires, protect the slope, etc. It is also effective in preventing surface erosion caused by rainwater on shoulders and slopes. It is also strong against shade and dryness, is evergreen throughout the year, and is effective in improving the winter landscape. Furthermore, once it grows up, it has many excellent effects in terms of management costs, such as requiring little maintenance. Due to these benefits, Ryu no beard and Yabulan are used for dike vegetation, forest zone greening, slope greening instead of lawn, as well as vegetation on roadside mediates, shoulders, and paddy shores. Very widely expected.

  However, the conventional method for producing Ryu no beard and Yablanc seedlings is based on the stock split, and it has been difficult to produce in large quantities all at once. That is, as a reason for the seedling production of Ryu no beard and Yablanc, there is a feature that it does not germinate easily when sown normally. In addition, according to the stock split, it is also easy to breed. Therefore, there is a reason why the breeding technology did not develop from the stock split and the seedling technology did not develop.

Therefore, in the greening work using such Rhino beard and Yablanc seedlings, it is necessary to artificially plant the planted pot seedlings (planting work). It is necessary to see the construction example of land cover planting by Ryunohige and Yablanc while having the characteristics that the workability is inferior and the overall cost is high, and the superiority of post-management is extremely high I could hardly do it. Therefore, production of rhododendron and Yablanc seedlings by seedlings from seeds is desired, but the production method has not been established until now, and it is not used as a seed for ground spraying method.

  The present invention is capable of producing a large amount and stably at any time regardless of the season by seedling seedlings by managing and treating Ryu no beard and Yablanc seedlings under certain conditions. The biggest feature is the realization of a seedling production method, and a cell seedling obtained by the method, or a ground cover planting method using a mixed culture obtained in the process. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for producing seedlings of Ryu no beard and Yablanc according to the present invention and a ground cover planting method using the method will be described below with reference to the drawings.

  FIG. 1 is a flowchart showing a method for producing seedlings of Ryu no beard and Yablanc according to the first embodiment of the present invention. In the seed and seedling production method, first, a temperature adjustment process is performed for a predetermined period of time under a predetermined temperature condition on the seeds of Ryu no beard and Yablanc. The seeds after such temperature adjustment treatment are immersed in the seeds for a day and night so that the seeds absorb moisture, and then the molting treatment is performed on the seeds. Thereafter, the seeds are sown on a predetermined culture medium or an arbitrary medium filled in a seedling container or a vegetation mat, thereby finally producing seedlings of rhubarb and Yablanc from the culture medium.

  Regarding the temperature adjustment treatment, conventionally, a method for making seeds experience a dormant state by low temperature treatment and feeling the season to activate the seed activity is widely known. From the viewpoint of improving the germination rate by such low-temperature treatment, in the temperature adjustment treatment according to the present invention, the temperature adjustment treatment is performed under the conditions shown in Table 1 and Table 2 below in order to determine the optimum temperature condition and period. The germination rate for 45 days after sowing was verified for the seeds.

  As shown in Table 1 and Table 2, the germination rate when the temperature condition is 3 ° C. or less is about 20% in all periods for both Ryu no beard and Yablanc. It is speculated that the moisture contained in the seeds may have been frozen, thus affecting germination. In addition, if the temperature condition is 11 ° C. or higher, the seeds do not enter a dormant state without being subjected to a low temperature treatment. Therefore, no stimulation is given to the seeds, and the germination rate is about 50% in all periods as in the case of untreated seeds. On the other hand, when the temperature conditions are 4 ° C., 7 ° C. and 10 ° C., the seeds do not enter the dormant state when the period is 3 days, and the germination rate is about 50% without changing to the untreated seeds. If the period is 7 days or longer, the seed becomes dormant, and the germination rate is dramatically improved to around 80%. Therefore, in the temperature adjustment process according to the present invention, it is most desirable that the temperature condition is 4 ° C. to 10 ° C. and the period is 7 days or more.

  The seed subjected to the temperature adjustment treatment is subsequently immersed for one day and night so that the seed absorbs moisture, and thereafter the seed is molted. In adopting such a molting treatment, in order to verify its effectiveness, comparison verification with the effect of performing various other treatments as shown in Table 3 and Table 4 below was performed. In addition, at the time of comparative verification, the germination rate for 75 days after sowing was verified for seeds that had been washed with water and soaked overnight for a day.

  As shown in Tables 3 and 4 above, the germination rate after 75 days after sowing for both rhododendron and Yablanc is about 55% for untreated (with skin), about 80% for molting, and sandy rice As a result, the treatment was about 25%, and the sand padding treatment + germination accelerator was about 35%. In addition, it is estimated that mold | fungi have generate | occur | produced from the early stage about the sand blasting process and the sand blasting + germination promoter process, and it has been estimated that it had influenced the germination greatly. From the above results, it was found that the molting treatment effectively acts on the germination rate of Ryu no beard and Yablanc.

  Next, by mixing the rhododendron and yaburan seeds that have undergone the above-mentioned treatments in a predetermined culture soil, a mixed culture soil of soil and seeds is obtained. Such culture is not particularly limited, but in order to determine the optimal culture for the seed production method according to the present invention, as shown in Table 5 and Table 6 below, comparative verification of germination rates in various cultures is performed. went.

  As shown in Table 5 and Table 6, the germination rate after 130 days after sowing for both rhododendron and Yablanc is about 60% for hydrous cotton, about 80% for the agar medium, and about 40% for bark compost. , Raising seedling soil (using soil mainly made of peat moss and vermiculite) is composed of around 60% conifer bark with a mass ratio of about 50%, organic soil conditioner with a mass ratio of about 30%, and red soil with a mass ratio of about 20%. As a result, cultivation soil was less than 90%. In bark compost, nearly half of the seedlings died after germination. From the above results, as a suitable soil for the seed and seedling production method according to the present invention, a soil composed of soft bark with a mass ratio of about 50%, an organic soil improving material with a mass ratio of about 30%, and a red soil with a mass ratio of about 20% is Ryunohige. In addition, it is effective for the germination rate of Yablanc, and it is desirable to employ such a culture soil. In addition, as a reason for selecting such soil cultivation ingredients, red soil is effective in order to maintain a high water retention capacity for about 60 days from seeding to germination for about 45 days after sowing, and conifer bark is used to ensure water permeability after germination. This is because it is effective to use. In addition, such a coniferous bark is advantageous in terms of cost because it can use waste materials discharged at the time of wood production or the like, and further exhibits an excellent effect on the stability of the culture medium after ground cover construction described later. And about mixing of organic soil improvement material, it is because it works effectively for nutrient supply to seeds and seedlings, growth promotion, and rooting promotion. Such an organic soil improving material is not particularly limited, and examples thereof include grass charcoal, bark compost, and a mixture thereof.

  It is also conceivable to add a moisture retention additive having a mass ratio of 3% to 5% to the above soil. Examples of the moisture retention additive include Kanuma soil. The Kanuma soil has a nodule structure, and since the nodule has many pores, it is easy to pass water and air and has a property of easily holding moisture. The water in the agglomerates is invaded by capillary tension, but water retention is also performed by the adsorption force of silty clay. It is said that the content of allophane (the main clay mineral of volcanic ash soil) contained in silty clay contributes greatly to this, but the allophane content of Kanuma soil is about 50% or more, and the water content ratio is Because it is expensive, Kanuma soil is effective as an additive.

  It is also conceivable to add carbon powder having a mass ratio of about 2 to 5% to the above-mentioned soil. Although there is no particular limitation on such charcoal powder, vegetable charcoal powder such as charcoal powder or bamboo charcoal powder is desirable in consideration of compatibility with soil. Such charcoal powder has a sterilizing effect on soil and further has a property of adsorbing harmful components.

  By seeding the seeds of Ryu no beard and Yablanc on the above-mentioned soil filled in a seedling container or a vegetation mat or an arbitrary medium on which the above-mentioned culture soil is laid, seeds of Ryu no beard and Yablanc will be allowed to grow. In addition, when seedling Ryu no beard and Yabulan seedlings, seedlings of Ryuno Beard and Yablanc which have been subjected to the above-mentioned management and treatment in advance are mixed with the above-mentioned culture soil to obtain a mixed culture soil, and this mixed culture soil is grown in a seedling container by pressure injection An embodiment of conceiving seedlings of Ryu no beard and Yablanc seedlings by spraying and fixing to a vegetation mat or an arbitrary medium can be considered. By spraying and fixing to a seedling container, vegetation mat or any medium, it is possible to eliminate the need for filling and laying the culture medium in the seedling container, vegetation mat, or any medium, and in particular, In this case, it is excellent in the convenience of the juxtaposition work to the construction site in the ground cover work and contributes to the improvement of work efficiency.

  At this time, about the said seedling container, the aspect which uses a cell tray can be considered. The cell tray refers to a seedling raising container in which a large number of bowl holes that can be divided one by one are connected in a tray shape and a plurality of bowl holes are provided in a predetermined frame (for example, about 30 cm in length × about 60 cm in width). In general, pots of plastic pots are generally used for seedlings of rhododendron and Yablanc seedlings, but they need to be cultivated in a larger area than cell trays. Bulkiness and growth tend to vary. On the other hand, according to the cell tray, it is possible to cultivate in a small area, the land cost and the distribution cost are low, and it is possible to make the growth uniform.

  In order to verify the optimum water content in the seedling production method according to the present invention, the following Table 7 and Table 7 are used to verify the water content of the soil or mixed soil sowed with the seeds of Ryu no beard and Yablanc. As shown in FIG. 8, the comparative verification of the germination rate 2 months after sowing in each soil water content was performed.

  As shown in Tables 7 and 8 above, the germination rate after 2 months of sowing for both rhubarb and Yablanc is around 20% when the water content of the seed soil or mixed soil is 35%. When the moisture content is 40%, it is around 75%, when the moisture content is 50%, it is similarly around 75%, when the moisture content is 60%, it is also around 75%, and when the moisture content is 65%, 10%. The result was slightly over. In addition, the% display of moisture content is a mass ratio with respect to the culture soil or mixed culture soil which seed | inoculated the seed of the rhino beard and the yaburan. The germination rate when the moisture content is 35% is considered to be due to the lack of moisture, and the germination days require 120 days. The germination rate when the moisture content is 65% is considered to be due to excessive moisture, and nearly half of the germinated seedlings withered, and the seeds that did not germinate were emulsified and decayed. Oops. From the above results, as the optimal moisture content according to the present invention, a mass ratio of 40% to 60% is effective for the germination rate of rhubarb and yablanc, and it is desirable to adjust and manage the moisture so that the moisture content is such a content. .

  Furthermore, when seedling seeds of Ryu no beard and Yablanc, seedling management or mixed soil sowed with seeds of Ryu no beard and Yablanc can be managed as seedlings under the temperature conditions of 13 ° C. to 20 ° C. at night and 20 ° C. to 30 ° C. in the daytime. desirable. The typical seed germination temperature is around 15 ° C., but if it is less than 13 ° C. at night, it takes too many days for the seed to germinate, and it is 31 ° C. or more in the daytime. In addition, the moisture content of the mixed soil will be reduced too much due to evaporation, so it will be necessary to spray water frequently, and in some cases, the moisture absorption state of the seeds will not be maintained and germination will be affected. Because there is a possibility.

  In addition, when providing a temperature difference between daytime and nighttime and managing seedlings as described above, it is desirable to provide a set temperature difference of at least 7 ° C. between the highest temperature in the daytime and the lowest temperature at nighttime. Ryu no beard and Yabulan have a prominent nature around May, and the temperature difference between the highest and lowest temperatures in May in nature is approximately 7 ° C or higher. Therefore, it will play a role in promoting germination of Ryu no beard and Yablanc.

  FIG. 2 is a flowchart showing a method for producing seedlings of Ryu no beard and Yablanc according to the second embodiment of the present invention. In the seed and seedling production method, first, a temperature adjustment process is performed for a predetermined period of time under a predetermined temperature condition on the seeds of Ryu no beard and Yablanc. The seeds after such temperature adjustment treatment are immersed in the seeds for a day and night so that the seeds absorb moisture, and then the molting treatment is performed on the seeds. Then, the seeds after the molting treatment are dried to a moisture content of about 8%. Next, the seeds after the drying treatment are subjected to a cooling treatment for at least 7 days in a cooling state of 4 to 10 ° C., and the seeds after the cooling treatment are submerged for about 3 to 5 days to absorb moisture, and the seeds are molted. It is restored to the state immediately after the treatment (before the drying treatment). Thereafter, the seeds are sown on a predetermined culture medium or an arbitrary medium filled in a seedling container or a vegetation mat, thereby finally producing seedlings of rhubarb and Yablanc from the culture medium.

  In the seed and seedling production method according to the second embodiment, the process from the temperature adjustment process to the molting process is the same as that of the first embodiment. The seeds subjected to the molting treatment are subsequently subjected to a drying treatment until the water content becomes around 8%. Such drying treatment is performed in order to stop seed growth (germination) activity. However, if the seeds are completely dried to a moisture content of 0%, the seeds may be killed. Therefore, the drying process should be stopped at a moisture content of around 8%, which is the minimum necessary for maintaining the life of the seeds. It becomes.

  The seed subjected to the drying treatment is then subjected to a cooling treatment in a cooling state of 4 to 10 ° C. and for a period of at least 7 days. Such a cooling process is performed for the same purpose as the temperature adjustment process for the seeds performed earlier. Therefore, based on the data (Table 1 and Table 2) subjected to comparative verification in the temperature adjustment process, the temperature and period Is set. That is, as shown in Table 1 and Table 2 above, the germination rate when the temperature condition is 3 ° C. or less is about 20% in all periods for both Ryu no beard and Yabulan, and the temperature condition is If it is 11 ° C. or higher, the germination rate is about 50% in all periods. On the other hand, when the temperature conditions are 4 ° C., 7 ° C. and 10 ° C., the seeds do not enter the dormant state when the period is 3 days, and the germination rate is about 50% without changing to the untreated seeds. If the period is 7 days or longer, the seed becomes dormant, and the germination rate is dramatically improved to around 80%. Therefore, in the cooling treatment according to the present invention, it is most desirable that the temperature condition is 4 ° C. to 10 ° C. and the period is 7 days or more.

  Restoration for restoring the seed to the state immediately after the molting treatment (before the drying treatment) by submerging the seed after the cooling treatment for 3 to 5 days and allowing the seed to absorb moisture. Processing is performed. The seed thus restored is then sown in a predetermined culture medium or an arbitrary medium filled in a seedling container or a vegetation mat as in the first embodiment, or the seed is mixed with the culture medium. By obtaining a mixed culture and spraying and fixing the mixed culture to a seedling container, a vegetation mat or an arbitrary medium by pressure injection, seedlings of Ryu no beard and Yablanc will be obtained.

  In addition, in 2nd embodiment mentioned above, it is the same as that of 1st embodiment except the process (culture etc.) peculiar to this embodiment.

  By performing the second embodiment as described above, it is possible to store the seeds for a long time in a state of molting the seeds according to the time of sowing. That is, in the first embodiment, it was necessary to work backwards by calculating the number of days spent according to the sowing time, but in the second embodiment, the cooling treatment state is 3 to 5 days before the sowing time. It would be enough if the seeds were submerged.

  In addition, as a result of comparative verification, it has been found that the above-described second embodiment is not only performed because it has a temporal advantage in work but also exhibits an effect on the germination rate and germination speed. The verification results are shown in Table 9 and Table 10 below. In addition, in the comparison verification, the germination rate was verified for 75 days after sowing for the seed according to the first embodiment (first) and the seed according to the second embodiment (second).

  As shown in the above Table 9 and Table 10, the germination rate after 50 days, 60 days, 70 days, and 75 days after sowing for both Ryu no beard and Yabulan, the second embodiment is more than the first embodiment. As a result, the germination rate exceeded. Therefore, it was found that performing each treatment in the second embodiment effectively acts on the germination rate of Ryu no beard and Yablanc.

  Next, the ground cover method using cell seedlings obtained by the seedling production method of Ryu no beard and Yablanc using a cell tray as a seedling container will be described. The ground cover planting method is a method of using a cell tray as a seedling container in the above-mentioned method for producing seeds of Ryu no beard and Yablanc, planting the cell seedling obtained from the cell tray in an arbitrary medium, and fixing the seedling so that the seedlings of Ryu no mustache and Yablanc are grown. is there.

  Cell seedlings are approximately 2 cm in diameter, whereas conventional pot seedlings are approximately 9-12 cm in diameter. Therefore, when planting cell seedlings in an arbitrary medium, planting hole drilling is small, so that work efficiency is dramatically improved and the work period is shortened, and material costs and transportability are also contributed.

  Next, the ground cover planting method using the mixed culture soil obtained in the process of the above-described method for producing seeds of seeds and seeds of Ryu no beard and Yablanc will be described. FIG. 3 is a schematic explanatory diagram showing a work example of the ground cover greening method according to the present invention. The ground cover planting method is a method for spraying the mixed soil obtained in the process of the above-mentioned rhododendron and yaburan seedling production method onto an arbitrary medium by pressure injection, and fixing the soil on the spot to achieve seedling.

  When the medium to be ground cover is a medium in which weeds such as new sandy soil are difficult to grow, the mixed soil is applied to the medium from the seed sprayer or the high pressure pump tank car 1 via the spray hose 2. Direct spraying completes the ground cover planting method using Ryu no beard and Yablanc vegetation. In addition, when the medium to be greened is a medium in which weeds are likely to grow, rather than spraying the mixed soil directly on the medium, spraying a herbicidal mulching germination promoting material on the medium in the previous stage. After that, it is desirable to spray the mixed soil from the seed sprayer or the high pressure pump tank tank 1 onto the herbicidal mulching germination promoting material through the spray hose 2.

  In the above-mentioned ground cover greening method, a mode in which a mixed soil is further mixed with at least one of fertilizer, viscosity, and water and sprayed onto an arbitrary medium by pressure injection can be considered. The fertilizer is for promoting the germination and growth of rhododendron and Yablanc, and the viscosity is for preventing the collapse of the mixed culture soil, particularly when the medium to be ground cover is an inclined surface. This is because water promotes germination and growth of Ryu no beard and Yablanc as well as fertilizer.

  In consideration of the characteristics, the demands of Ryu no beard and Yabulan are expected in many scenes in the future, and according to the method for producing the seed of Ryu no beard and Yablanc according to the present invention, the seedlings of Ryu no beard and Yablanc have been difficult until now. Therefore, it is sufficiently possible to supply a large amount of demand because it can be mass-produced at any time regardless of the season. In addition, according to the ground revegetation method using the mixed soil obtained in the process of the seed and seedling production method, the seedlings of rhododendron and Yablanc can be similarly produced. Land cover planting can be done with a simple task of spraying mixed soil with Ryu no beard and Yablanc seeds and soil. is there.
