【発明の詳細な説明】 （産業上の利用分野） 本発明は野菜や草花、苗木等の育苗に利用する育苗容器
の構成に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a structure of a seedling raising container used for raising seedlings of vegetables, flowers, seedlings and the like.

ある。(Prior art and its problems) In recent years, as containers used for raising plants, plastic containers, paper, and peat moss containers have been used in place of conventional unglazed pots because of their light weight and economy. However, there are drawbacks such as lack of ventilation and water permeability, root rot, strength problem, or environmental degradation due to non-natural decomposition.

発生したり成長が遅くなる等の問題がある。In addition, as shown in JP-A-57-49225, there is also seen a seedling raising container formed by a non-woven fabric in which a thermoplastic synthetic fiber web is partially thermocompressed and bonded. However, even if the container is formed without considering the side wall density of the container and the pore size of the porous body to be formed, the size and density of the hole size formed on the side wall is too large or too small as compared with a certain value. When the water is irrigated, the water will evaporate rapidly and the soil will dry out immediately, resulting in poor water retention and the planting material will die, or the roots of the plant will come out and cause root breakage during transplantation. , Pests and microorganisms invade and adversely affect the growth of plants. On the other hand, if the pore size is small and the density is too high, there is a problem that water permeability is poor at the time of irrigation, air permeability is impeded, root rot occurs, and growth slows down.
（課題を解決するための手段） 本発明は上記問題点の解決に当り、成型された容器の側
壁が直径50μｍ未満の微細な孔を有し、かつ含有する熱
接着性繊維の溶融によりフイルム化した通気度が10〜0.
1cc/cm2/secの多孔質壁体を形成し、底部は上記側壁よ
りも大きな50〜500μｍの孔径を有する粗なる繊維結合
構造とした育苗容器を得ることによりその課題を解消し
たものである。(Means for Solving the Problems) In solving the above problems, the present invention has a sidewall of a molded container having fine pores with a diameter of less than 50 μm, and is formed into a film by melting the heat-adhesive fiber contained therein. The air permeability is 10-0.
The problem is solved by obtaining a seedling container having a coarse fiber-bonded structure having a porous wall of 1 cc / cm 2 / sec and a bottom having a pore size of 50 to 500 μm larger than the side wall. .
一般に育苗容器としては通気性に優れていることが不可
決であるが、通気度が良すぎると保水性が低下して容器
内の培地が急激に乾燥する結果植込んだ植物が枯れ易く
なり、毎日潅水を欠かすことが出来ず手数がかかる。In general, it is indeterminable that the container for raising seedlings has excellent air permeability, but if the air permeability is too good, the water retention will decrease and the medium in the container will suddenly dry, and the plant that has been implanted will easily die, Irrigation is indispensable every day, and it is troublesome.
従って本発明の容器側壁の通気度としては10〜0.1cc/cm
2/sec、みかけ密度は0.3g/cm3〜0.8/cm3であることが望

m3未満になると培地からの水分の蒸発乾燥が速くなり、
又0.8g/cm3をこえると水分の透水性、蒸発が遅くなり根
腐れや成長に悪影響を及ぼすことになる。Therefore, the air permeability of the container side wall of the present invention is 10 to 0.1 cc / cm.
It is desirable that the apparent density be 2 / sec and the apparent density be 0.3 g / cm 3 to 0.8 / cm 3 . If the air permeability exceeds 10 cc / cm 2 / sec, the medium will dry faster and the water retention will decrease, and if it is less than 0.1 cc / cm 2 / sec, air holes will be blocked during irrigation and the drying will be slow and root rot will occur. appear. To meet the above requirements, 10 fibers are used.
Polyolefin-based composite fibers with denier or less (PP-PE
Type), polyester type (PET-PE type, PET-low melting point PE)
T), heat-adhesive fibers such as polyamide-based composite fibers (Ny66-Ny6) and synthetic fibers, such as polyester, polypropylene, polyamide, acrylic, modacrylic, polyvinylidene chloride and the like, or porous fibers or cellulosic fibers thereof,
Preferably, a fiber having a fineness of 0.1 to 5 denier is used, and a card or a random web is formed, or a fiber in which fibers are lightly entangled by a needle punch is used. It is desirable that the blending ratio of the heat-adhesive fiber in the web is 30% (weight) or more, and the heat-adhesive fiber is melt-pressed at the time of thermoforming of the seedling raising container to form a film on the side wall, and the pore diameter is 50 μm or less. With an apparent density of 0.3
Constitute the porous sidewalls of 0.8 g / cm 3. Density 0.3g / c
When it is less than m 3 , evaporation of water from the medium becomes faster,
On the other hand , if it exceeds 0.8 g / cm 3 , water permeability and evaporation will be delayed, which will adversely affect root rot and growth.
また容器の底部は通水性が十分であり、虫・微生物が侵
入しがたい構造とする為、孔径が50〜500μｍ好ましく

物がいつまでも水分過剰となりて根腐れを起すので好ま
しくなく、また500μｍ以上であると数十分で排出さ
れ、ナメクジや微生物の侵入が多くなる。In addition, the bottom of the container has a sufficient water permeability and a structure in which insects and microorganisms are hard to invade. Therefore, the porous fiber-bonded structure having a pore diameter of 50 to 500 μm, preferably 100 to 500 μm was used. If the pore size is less than 50 μm, the water permeability will be insufficient, it will take several days or more for the excess water to be drained from the container, and it will be unfavorable because the planted plants will always have excess water and root rot, and it is also 500 μm or more. It is discharged in tens of minutes, and the invasion of slugs and microorganisms increases.

る。Also, in order to make it easier to pass the roots of the plant as it grows and to make it easier to remove the roots from the container at the time of transplantation, adjust the pressure during thermoforming so that the fiber density is 0.01 to 0.2 g / cm 3, and weaken the bonding force between fibers. To form. Example 1 of the present invention will be described in detail below.

力の弱い（0.8kg/2cm巾）育苗容器が得られる。The fiber sheet was thermoformed at a mold temperature of 120 ° C., a pressure of 2 tons, and a pressure time of 80 seconds. The obtained seedling container has a weight of 10 g, a wall thickness of 0.8 mm, a height of 80 mm, an opening diameter of 90 mm, and a bottom diameter of 65 mm. As shown in the drawing, the side wall (2) of the container (1) is heat-adhesive fiber. Is melt-pressed to form a film, which has fine pores with a density of 0.5 g / cm 3 and a pore size of 30 μm or less.
20-100 pieces have a uniformly distributed air permeability of 0.9 cc / cm 2 / sec. Also, the bottom part (3) is not made into a film by adjusting the gauge of the male and female dies, and the density is 0.1 g / cm 3 and the pore size is 50 to 200 μm.
A seedling-growing container having a weak interfiber binding force (0.8 kg / 2 cm width) in which 100 to 300 holes (4) are evenly dispersed can be obtained.
