本発明は野菜や草花、苗木等の育種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) Seedlings The present invention relates to the structure of a seedling-growing container used for breeding vegetables, flowers, seedlings, and the like.
（従来の技術及びその課題）
近年、植物の育苗に使用されている容器は従来の素焼き

容器や紙、ピートモス製容器が用いられているが、通気
、通水性がなく、根腐さが発生したり、強度の問題或は
自然分解しないので環境汚染が発生するなどの欠点があ
る。(Prior art and its problems) In recent years, containers made of plastic, paper, and peat moss have been used instead of the traditional clay pots for raising plant seedlings due to their light weight and economic efficiency. However, it has disadvantages such as lack of ventilation and water permeability, root rot, strength problems, and environmental pollution because it does not decompose naturally.

が発生したり成長が遅くなる等の問題がある。Furthermore, as shown in JP-A No. 57-49225, there is also a seedling-raising container formed from a nonwoven fabric in which a thermoplastic synthetic fiber web is partially bonded by thermocompression. However, even if a container is formed without considering the side wall density of the container and the pore diameter of the porous body to be formed, the pore diameter and density formed in the side wall may be too large or too small than a certain value. Even if you water, the water evaporates rapidly and the soil dries up quickly, resulting in poor water retention (the planting material may wither, or the roots of the plant may come out and cause root breakage when transplanting). In addition, pests and microorganisms may invade and have a negative impact on plant growth.Also, if the pore size is too small and the density is too high, water permeability during irrigation will be poor and air permeability will be inhibited, causing problems such as root rot and slow growth. There is.

よりその課題を解消したものである。(Means for Solving the Problems) The present invention solves the above-mentioned problems by forming a molded container in which the side wall has fine pores with a diameter of less than 50 μm and is formed into a film by melting the thermoadhesive fibers contained therein. The ventilation rate is 10
Forming a porous wall of ~0.1 cc/cJ/sec,
This problem has been solved by obtaining a seedling-growing container whose bottom part has a rough fiber-bonded structure with a pore diameter of 50 to 500 μm, which is 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。Generally speaking, a container for raising seedlings must have good ventilation, but if the ventilation is too good, the water retention capacity will decrease and the medium inside the container will dry out quickly, making the planted plants more likely to wither. Irrigation is necessary and time-consuming every day.

り根腐れや成長に悪影響を及ぼすことになる。If it is less than /sec, air holes will be blocked during irrigation, drying will be slow and root rot will occur. In order to satisfy the above requirements,
The fibers used include polyolefin composite fibers (PP-PE) and polyester (PET-PE) with a density of 10 deniers or less.
Heat-adhesive fibers and synthetic fibers such as PE type, PET (low melting point PET), polyamide composite fiber (Ny66-Ny6),
For example, polyester, polypropylene, polyamide, acrylic, modacrylic, polyvinylidene chloride, etc., porous fibers or cellulose fibers thereof, preferably 0.1 to
A fiber with a fineness of 5 denier is used, and a card or random web is formed, or the fibers are lightly entangled by needle punching. The blending ratio of the thermoadhesive fibers in the web is desirably 30% (by weight) or more, and the thermoadhesive fibers constitute the porous side walls of the seedling growing container during thermoforming. Density is 0.3g/ct
When it is less than A, the moisture from the medium evaporates and dries quickly,
If the amount exceeds 0.8 g/-, water permeability and evaporation will be slowed down, causing root rot and growth to be adversely affected.

。The bottom of the container has a porous fiber-bonded structure with a pore diameter of 50 to 500 μm, preferably 100 to 500 μm, in order to have sufficient water permeability and prevent insects and microorganisms from entering. If the pore diameter is less than 50 μsh, water permeability will be insufficient, and it will take several days or more for excess water to drain from the container, and the planted plants will remain in excess water for a long time, causing root rot, which is not desirable. If it is, it will be expelled within a few minutes, and slugs and microorganisms will often invade.
