Description
この考案は、水稲育苗における保水・保肥に関する育苗資材の積層構造に関するものである。 This device relates to a layered structure of seedling materials related to water retention and fertilization in paddy rice seedlings.
従来の水稲育苗法は、肥料が混じった床土を丸穴の空いた育苗箱（270mm × 570mm×30mm）に入れ、そこに種籾（１５０ｇ前後）播種し、更に覆土、灌水を加えて２０〜２５日を要して稚苗に生育させて水田に移植する。 The conventional paddy rice seedling method is to place fertilizer-mixed floor soil in a round holed seedling box (270mm x 570mm x 30mm), sow seed seeds (around 150g) there, and add soil covering and irrigation for 20 ~ It takes 25 days to grow into young seedlings and transplant to paddy fields.
しかし、この方法には以下の問題があった。
その一は、育苗箱の容積そのものが狭小、且つ、床土量も少なく、従って、期間中の必要保水量・保肥量の維持に難点があること。
However, this method has the following problems.
The first is that the volume of the seedling box itself is small and the amount of floor soil is small, so there is a difficulty in maintaining the required water retention and fertilizer retention during the period.
その二は、灌水時に水は上から下へと移行し、最終的には底穴から箱外へ流出し、同時に床土に含まれている肥料成分も連動して箱外に流亡してしまう。 Second, when watering, the water moves from top to bottom and eventually flows out from the bottom hole to the outside of the box, and at the same time, fertilizer components contained in the floor soil are washed away outside the box. .
その三は、一、二の現象により結果として、根量及び草丈も十分に伸張せず田植え時の初期活着の活力も弱含み傾向である。 As for the third, as a result of one or two phenomena, the root amount and the plant height are not sufficiently stretched, and the vitality of initial establishment at the time of rice planting tends to be weak.
その四は、市販床土の重量は、１袋２０ｋｇが一般的であり、これを育苗箱に分散した場合、１箱の床土重量は４ｋｇ程度で、更に移植直前の重量は育苗中の灌水量も加わり、実質は７ｋｇ程度まで増量するため、高齢者及び女性には負担の大きい作業と言わざるを得ないものであった。 The fourth is that the weight of commercially available floor soil is generally 20 kg per bag, and when this is dispersed in a seedling box, the weight of the floor soil in one box is about 4 kg, and the weight just before transplanting is irrigation during the seedling Since the amount is added and the actual weight is increased to about 7 kg, it must be said that the work is a heavy burden on the elderly and women.
尚、上記に鑑み、育苗箱を使用しない種籾埋込育苗マットは存在している。例えば、特許文献１のように。
In addition, in view of the above, there exists a seedling embedded seedling mat that does not use a seedling box. For example, as in
そこで、この考案の課題は、育苗箱内において、苗の根張り、コスト、重労働作業を軽減させることのできる水稲育苗における保水・保肥に関する育苗資材の積層構造を開発・提供することにある。 Therefore, an object of the present invention is to develop and provide a layered structure of seedling material related to water retention and fertilization in paddy rice seedling that can reduce seedling rooting, cost, and heavy labor work in a seedling box.
この考案の水稲育苗における育苗資材の積層構造は、
適宜な縦・横・深さ寸法を有し、上部を開口し、底部には小穴を複数形成した箱本体を設け、
該箱本体の底面には、保水紙を敷設し、
該保水紙の上に、育苗箱の容積の１／２程度の床土を敷設し、
該床土には、種籾を播種し、
播種された種籾の上部に、覆土を被せた
ことを特徴とする。
The laminated structure of the seedling material in the paddy rice seedling of this device is
A box body with appropriate vertical, horizontal, and depth dimensions, with an opening at the top and a plurality of small holes at the bottom,
On the bottom of the box body, lay water retaining paper,
On the water-retaining paper, lay a floor soil of about 1/2 the volume of the seedling box,
The floor soil is seeded with seed pods,
It is characterized by covering the top of the sowed seed potato with cover.
この考案によると、箱本体の底部に保水紙を敷設することにより、保水部材を構成する高吸水性のアクリル重合体が水と接触すると、速やかにこれを吸水し、多少の圧力では水を放出せず、箱底でアクリル系ポリマーによる膜を張り、灌水時においても水及び肥料分の箱外流出を大幅に抑制する等の効果を有する等の極めて有益なる効果を奏する。 According to this device, by laying water retaining paper on the bottom of the box body, when the highly water-absorbing acrylic polymer constituting the water retaining member comes into contact with water, it quickly absorbs water and releases water at some pressure. Without using a film made of an acrylic polymer on the bottom of the box, there is an extremely beneficial effect such as having an effect of significantly suppressing outflow of water and fertilizer out of the box even during irrigation.
また、この水、肥料の流出が大幅に抑制できることにより、床土量、肥料分も従来比でそれぞれ半減量（−５０％減、覆土量は慣行）で育苗は十分可能であり、従来の床土量コストの半減、運搬労力の激減が図れ、さらに、根張りが向上する等の極めて有益なる効果を奏するものである。 In addition, since the outflow of water and fertilizer can be greatly suppressed, the amount of bed soil and fertilizer can be reduced by half (-50% less, the amount of soil covering is conventional), respectively, so that seedlings can be grown sufficiently. The amount of soil cost can be reduced by half, the labor for transportation can be drastically reduced, and further, it can provide extremely beneficial effects such as improved rooting.
以下、この考案について詳細に説明する。尚、この考案においては、以下の記述に限定されるものではなく、この考案の要旨を逸脱しない範囲においては適宜変更可能である。 Hereinafter, this device will be described in detail. In addition, in this invention, it is not limited to the following description, In the range which does not deviate from the summary of this invention, it can change suitably.
先ず、この考案の一実施例を図面に基づいて詳述すると、適宜な縦・横・深さ寸法を有し、上部を開口し底部には小穴を複数形成した箱本体（１）を設け、該箱本体（１）の底面には、保水部材（２）を敷設し、該保水部材（２）の上に、育苗箱の容積の１／２程度の床土（３）を敷設し、該床土（３）には、種籾（４）を播種し、播種された種籾（４）の上部に覆土（５）を被せてなることを特徴とする水稲育苗における保水・保肥に関する育苗資材の積層構造から構成される。 First, an embodiment of the present invention will be described in detail with reference to the drawings. A box body (1) having appropriate vertical, horizontal, and depth dimensions, having an opening at the top and a plurality of small holes at the bottom is provided. A water retaining member (2) is laid on the bottom surface of the box body (1), and a floor soil (3) about half the volume of the seedling box is laid on the water retaining member (2). The seed material (4) is sown on the floor soil (3), and the seed material (4) is covered with the cover soil (5) on the top of the sown seed potato (4). It consists of a laminated structure.
尚、箱本体（１）は、既存の水稲用育苗箱を利用してよく、箱本体（１）の寸法は、その一例としては、幅５７０ｍｍ、奥行き２７０ｍｍ、高さ３０ｍｍ程度を基準とする。 The box body (1) may use an existing rice seedling growing box. The dimensions of the box body (1) are, for example, a width of about 570 mm, a depth of 270 mm, and a height of about 30 mm.
そして、前記保水部材（２）は、その一例を述べると、紙片（横５７０ｍｍ、縦２７０ｍｍ）２枚を重ね、この紙片の間に、粉末状の高吸水性のアクリル系ポリマー７ｇを播き、サンドイッチ状にして両紙片をカシメて構成し、これら紙片に一定間隔を隔てて、通穴（２ａ）を設けたものであり、高吸水性のアクリル系ポリマーは、水と接触すると速やかに水分を吸収し、少しの圧力ではこの水分を排出することはないものであり、紙片は高吸水性のアクリル系ポリマーと剥がれ、水稲の根の発育により細かく分断されやがて無くなるものである。 An example of the water retaining member (2) is as follows. Two pieces of paper (width 570 mm, length 270 mm) are stacked, and between these pieces of paper, 7 g of a powdery superabsorbent acrylic polymer is seeded, and sandwiched. Both paper pieces are crimped and formed, and through holes (2a) are provided in these paper pieces at regular intervals. A highly water-absorbing acrylic polymer absorbs moisture quickly when it comes into contact with water. However, this moisture is not discharged by a little pressure, and the piece of paper is peeled off from the highly water-absorbing acrylic polymer, and is finely divided by the growth of rice roots and eventually disappears.
また、床土（３）は、肥料成分を含んでおり、保水部材（２）の性質を利用すれば箱底にアクリル系ポリマーによる膜状を形成し、灌水時においても水及び肥料分の箱外への流出を大幅に抑制するものである。 In addition, the floor soil (3) contains a fertilizer component, and if the properties of the water retaining member (2) are used, a film-like film made of an acrylic polymer is formed on the bottom of the box. This greatly suppresses the outflow to
尚、箱本体（１）内に使用する覆土（５）の量は、慣行量に準じるものである。 In addition, the quantity of the covering soil (5) used in a box main body (1) is based on a customary quantity.
次に、下記の〔表１〕は、流出肥料の数値を測定した表であり、該表〕に基づいて説明すると、区分は、この考案の実施例（本考案区と称す）と、比較例（対照区と称す）を示したものであり、これらの数値（流出濃度ｐｐｍ）は、それぞれ灌水終了２０分後の流出水より検出したものである。 Next, [Table 1] below is a table in which the values of the spilled fertilizer were measured, and based on this table], the classification is an example of the present invention (referred to as the present invention section) and a comparative example. (Referred to as a control group), and these numerical values (outflow concentration ppm) are respectively detected from the outflow water 20 minutes after the end of irrigation.
また、灌水量は、それぞれ１回分が１リットル（但し、灌水日は毎日実施）であり、採集水日は、１日目、１０日目、１５日目、そして２０日目の４回行なったものである。
従って、４回分の灌水量は本考案区、対照区ともに、４０００ｃｃであり、流出水量は本考案区は１，１５０ｃｃ、対照区は１，６１０ｃｃであった。
The irrigation amount was 1 liter for each irrigation (however, the irrigation day was carried out every day), and the collection water was performed 4 times on the 1st, 10th, 15th and 20th days Is.
Therefore, the amount of irrigation for 4 times was 4000 cc in both the inventive zone and the control zone, and the amount of effluent was 1,150 cc in the inventive zone and 1,610 cc in the control zone.
次に、〔表１〕に基づいて、肥料の三大要素である窒素（Ｎ）、リン酸（Ｐ）、カリ（Ｋ）について、この考案である本考案区と、比較例である対照区との流出肥料の数値を比べると、窒素（Ｎ）は、２０日目の測定で、本考案のものが、１．１に対して比較例では０．２であり、リン酸（Ｐ）については、２０日目の測定で、本考案のものが、０．９に対して比較例では０．３であり、カリウム（Ｋ）に対しては、２０日目の測定で、本考案のものが、２．８に対して比較例では２．２であった。これにより、本考案では肥料の三大要素である窒素（Ｎ）、リン酸（Ｐ）、カリ（Ｋ）のすべてにおいて、比較例に勝ったものであり、肥料の流出が少ないことが判明した。 Next, based on [Table 1], for the three major elements of fertilizer, nitrogen (N), phosphoric acid (P), and potash (K), the present invention zone which is this device and the control zone which is a comparative example Compared with the numerical value of spilled fertilizer, nitrogen (N) is measured on the 20th day, the present invention is 0.2 in the comparative example compared to 1.1, about phosphoric acid (P) Is the measurement of the present invention on the 20th day, and is 0.3 in the comparative example against 0.9, and for potassium (K), the measurement of the 20th day However, it was 2.2 in the comparative example compared to 2.8. As a result, it was found that in the present invention, nitrogen (N), phosphoric acid (P), and potash (K), which are the three major elements of fertilizer, were superior to the comparative example, and there was little outflow of fertilizer. .
