Abstract

PURPOSE:To simultaneously embed many seeds in the optimal positions of a connected medium material by employing belt-like materials each prepared by folding a sheet-like material not giving any inhibitory action on the germination and rooting of the seeds and to the subsequent growth of the generated seedlings and subsequently disposing many seeds in the valley of the folded sheet-like material. CONSTITUTION:Notches 8 are formed over the whole length of sowing-scheduled positions of a connected medium material 11 composed of inorganic or organic porous molded products 7 and belt-like materials are inserted into the notches 8, respectively, for the objective sowing, the belt-like materials each being prepared by folding a sheet-like material 2 substantially not giving any inhibitory action on the germination and rooting of plant seeds 1 and on the subsequent growth of the generated seedlings in the length direction and subsequently disposing many seeds 1 in the formed valley portion 3 at approximately constant intervals.

盤目状の連接培地材に加工されていることがある。Normally, when producing plants using an inorganic or organic porous molded body as a medium, the porous molded body is generally used for seed germination and seedling raising, and then transplanted and cultivated. In that case, the porous molded body is provided with holes or notches for burying the seeds, and furthermore, slits are provided to separate the plants into individual plants after germination. It is sometimes processed into a base grain-like continuous medium material consisting of small prismatic or cubic block medium materials, leaving a part of the sides intact.

、露地に移植され通常の栽培に用いられもする。With the continuous culture medium constructed in this way, seeds are sown in the holes or notches, or if no holes are provided, they are sown directly on the top of the medium to germinate and raise seedlings, and then the seeds are sown on the sides. It can be divided into plant parts and used for hydroponic cultivation, or it can be transplanted into open ground and used for regular cultivation.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

を各ブロックの穴や切り込みの中、或いは穴等のない場
合はブロック上面を指などで凹ませ埋め込むか、又は種

物によっては播種機で行うこともある。In this case, the seed shape differs depending on the plant, so the method of sowing will differ depending on the plant, but - for boat fishing, the seeds are manually placed into the holes or notches of each block, or if there are no holes, the seeds are placed on the top of the block. Seeds may be sown one by one by embedding the seeds indented or by simply placing the seeds on the top surface, or depending on the plant, this may be done with a seeding machine.

しかし一般に行なわれる人手による播種の場合には当然
膨大な作業時間を必要とする問題があった。However, in the case of manual sowing, which is generally carried out, there is a problem in that it requires an enormous amount of work time.

従って本発明の目的とする所は、播種作業の省力化、効
率化を可能とし、且つ十分な発芽と生育を可能とする種
子の播種方法を提供することにある。Accordingly, an object of the present invention is to provide a method for sowing seeds that enables labor-saving and efficient sowing work, and also enables sufficient germination and growth.

〔課題を解決するための手段〕[Means to solve the problem]

即ち本発明は無機又は有機の多孔質成型体で構成された

り込みを設けると共に、植物種子の発芽、発根とその後
の生育に実質的な阻害作用を及ぼさないシート状体を長
さ方向に折り曲げて生ずる谷部にほぼ一定間隔て種子を
設置してなる帯状体を前記切り込みに挿入することを特
徴とする播種方法である。That is, the present invention provides a continuous medium material made of an inorganic or organic porous molded material with incisions in advance over the entire length of the fixed position of the sowing seeds, and also has a substantial inhibiting effect on the germination, rooting, and subsequent growth of plant seeds. This seeding method is characterized by inserting into the notch a belt-shaped body in which seeds are placed at approximately regular intervals in the valleys formed by folding a sheet-shaped body that does not affect the grain in the length direction.

以下本発明の詳細な説明する。The present invention will be explained in detail below.

先ず本発明で種子が設置されるシート状体は、種子及び
発芽した苗に阻害作用を有する成分を実質的に溶出せず
、苗から伸長する根が容易に貫通する材質のものであれ
ばいずれでもよく、たとえば天然または合成繊維からな
る布、紙、セルロースフィルム、合成樹脂などが考えら
れるが、実用的見地から水や微生物による分解性を有す
る紙が、砺格や加工性からも優れている。First, the sheet-like body on which the seeds are placed in the present invention may be any material as long as it does not substantially elute components that have an inhibitory effect on the seeds and germinated seedlings and is easily penetrated by roots extending from the seedlings. For example, cloth made of natural or synthetic fibers, paper, cellulose film, synthetic resin, etc. can be considered, but from a practical standpoint, paper that is degradable by water and microorganisms is superior in terms of its strength and processability. .

またシート状体の折り曲げ部の形状としては、Ｖ形、Ｗ
形いずれでもよく、種子の大きさや形状、性質に合わせ
て選択すればよい。このように折り曲げることによって
帯状体に形成された谷部に種子を設置するわけであるが
、この場合、種子間隔は連接培地材の基盤目の幅とほぼ
一致するようにすれば良い。In addition, the shape of the bent portion of the sheet-like body may be V-shaped or W-shaped.
Any shape may be used, and the choice can be made depending on the size, shape, and properties of the seeds. By bending the strip in this way, the seeds are placed in the valleys formed in the strip. In this case, the seed spacing may be made to approximately match the width of the base mesh of the continuous medium material.

また、シート状体に種子の発芽及び生育にとっても好都
合な種々の加工、処理を施すことも必要に応じて行えば
よい。たとえば折り曲げたシート状体の一部を一定間隔

良いし、接着方法も化学的接着、物理的接着のいずれで
も良い。さらにはシート状体に吸収剤や肥料、農薬等を
塗布したり、或いは前述の種子の部屋の中に設置しても
良い。In addition, the sheet-like material may be subjected to various processes and treatments that are advantageous for seed germination and growth, as necessary. For example, by gluing parts of a folded sheet at regular intervals, seed chambers can be created in the strip. This ensures that the seeds are always spaced at regular intervals. Of course, the shape of the room mentioned here may be round, square, box-shaped, etc. with respect to the direction of the folded portion, and the bonding method may be either chemical bonding or physical bonding. Furthermore, the sheet-like material may be coated with an absorbent, fertilizer, agricultural chemical, etc., or may be placed in the aforementioned seed room.

さらにシート状体の種子周辺部に針穴程度の穴から２〜
５　ｍｍ程度の穴もしくは切れ目を入れることにより、
伸長する根の通過をより容易にすることも可能となる。Furthermore, there are 2 to 2 needle-sized holes around the seeds of the sheet-like material.
By making a hole or cut of about 5 mm,
It also becomes possible to more easily pass the elongating roots.

ただしここで言う穴もしくは切れ目の寸法あるいは長さ
は、用いる種子が脱落しない程度の寸法あるいは長さで
ある必要があることは言うまでもない。However, it goes without saying that the size or length of the hole or cut mentioned here needs to be such that the seeds used will not fall out.

シート状体の大きさは特に規定がない。この場合、種子

手方向の長さは特に規定はないが、育苗に使用する多孔
質成型体の大きさに一致していることが、実用上好まし
い。There are no particular regulations regarding the size of the sheet-like body. In this case, since the seed sowing depth varies depending on the type of plant, the length from the end of the sheet-like body to the bending line, that is, the width of the belt-like body, may be set to the optimum depth for the seeds of the plant to be cultivated. On the other hand, the length in the longitudinal direction is not particularly limited, but it is practically preferable that the length corresponds to the size of the porous molded body used for raising seedlings.

ある。Next, the inorganic or organic porous molded body used as the continuous medium material in the present invention may be any type as long as it is hydrophilic and does not elute substances harmful to plants during germination and seedling raising. Examples include rock wool fibers, glass fibers, ceramic fibers, carbon fibers, polyester fibers, cellulose fibers such as rayon, PvA
Fibers, inorganic or organic fibers such as wood fibers, or granular cotton, foamed ceramics, perlite, vermiculite, foamed fired clay, foamed phenolic resin, foamed urea resin,
There are inorganic or organic porous molded materials such as polyurethane foam.

適なように切り込みを作ればよい。In addition, in the present invention, in order to insert the strip with seeds, a notch is provided in advance over the entire length of the continuous medium material at the fixed position of the sowing seed, but the shape, size, and depth of the notch are Since the size and shape of seeds differ depending on the type of plant, it is only necessary to make incisions that are optimal for the seeds to be sown and raised.

Seedling management after this can be done in the usual way.

その例を見なかった優れた効果がもたらされる。By inserting the strips with seeds embedded in them into the notches in the continuous medium material, it is possible to sow large quantities of seeds in areas that could not be obtained using conventional methods, without the use of any particular machinery. As a result, it is possible to save labor and improve the efficiency of sowing work, and to achieve sufficient germination and growth, an unprecedented advantage that has not been seen before. This will bring about a positive effect.
