It also relates to a rice cultivation method (also referred to as groove cultivation here) in which rice seeds, seed cords (seed tapes) or seedling cords are placed at the bottom of the groove.
- a rice cultivation method also referred to as groove cultivation here
- rice seeds, seed cords (seed tapes) or seedling cords are placed at the bottom of the groove.
- paddy rice transplanting cultivation is widely practiced in which seedlings are once prepared and transplanted to the field because of a stable yield and an established cultivation system.
- the preparation of the nursery has a large burden of securing equipment for that purpose, labor, cost, etc., and the burden of labor generated from the weight of the nursery when transplanting the seedlings is also large.
- the structure of the machine becomes a limiting factor, and it is common to plant several plants per plant so that stock shortages do not occur.
- Non-Patent Document 1 So-called direct sowing cultivation (Non-Patent Document 1), in which rice paddy is sown directly in the field and cultivated with the aim of reducing the burden of adjusting the seedlings and preventing damage to the seedlings during planting and transplanting one plant per plant. Cultivation methods using seed tapes (Patent Documents 1 and 2, Non-Patent Documents 2 and 3) have become widespread. However, these methods have problems in poor germination, floating seedlings, fallen seedlings, low seedling rate, high lodging rate, and low yield as compared with transplant cultivation.

本発明に使用する種子紐は市販されているものを利用した((株)常総農興より購入)。綿100%の不織布(商品名:メッシュロン)にイネ(コシヒカリ)の種籾を、4cm間隔で封入したシードテープを使用した。直径5cmの塩ビ管(VU40)の円筒形の支持部材の周囲に(厚さ:約0.5cm、直径:31cm)の骨組みのみの円形スケルトン構造を有する第1及び第2の支持部材を内幅3cmの距離で固定されているリールを作成し、上記シードテープ約600m分を巻き取った。上記リールに巻き取ったシードテープを6日間、室内暗所で浸種(平均気温:15.2℃)し、その後、9日間自然光の下で催芽~緑化(平均気温:21.9℃、有効積算温度151.7℃)した。プラスチック製の箱型桶に6%次亜塩素酸ナトリウムを1000倍希釈した水(水と紐の腐敗、種籾由来の病害を防ぐ目的で使用)を入れ、発芽・緑化の間、縦方向に設置したリールの下半分が浸るようにし、1日当たり5~10回反転させ、苗紐全体が均一に水、光、空気及び重力に晒されるようにして、1.4葉期の苗紐を調製した。
直径37cm及び長側面長103cmのプラスチック製の円柱状のローラーの外周に、内周直径39cm、外周直径42cm、幅2.6cm及び外周面に深さ1.0cmの凹みを有する自転車のリム状のリングを上記円柱の外周にはめ込む形で長側面方向に30cm間隔で4本装着した溝置用ローラーを作成した。よく代掻きをした湛水水田面(水位は0~0.5cmであった)上を、上記溝置用ローラーを転がすと同時にリング上の凹みに沿わせて苗紐及び催芽処理をしたシードテープを導入し、作溝すると同時に苗紐及びシードテープを幅約2.5cm及び深さ約2cmの溝の底部に設置した(溝置したともいう)(
条間30cm、株間4cm、1株1本植え)。溝の底部に設置された苗紐及びシードテープは目視することができ、溝の埋め戻りは起きていなかった。並行して苗紐及びシードテープを水田表面に定置し栽培した(条間30cm、株間4cm、1株1本植え)。その後通常の栽培管理(代掻き時に施肥(一発かんた君(15-15-15-4)を30kg/10アール)、一般防除(溝置/定置から5日後にサンバード粒剤(3kg/10アール)、シクロパック粒剤(600g/10アール)、8日後にクリンチャージャンボ(1kg/10アール)、25日後にアクト粒剤(1kg/10アール)を施用した))をし、溝置/表面定置から43日目に苗立ち数の調査、生育程度の調査をし、穂数、1穂籾数、倒伏程度の調査は収穫適期行った。溝置/表面定置から約7か月後に収量構成要素の詳細な調査を行った。試験は5反復行った。
円柱状のローラーの後ろにプラスチック製の溝の断面形状を有する板を配置した作溝装置を作成した。よく代掻きをした湛水水田面(水位は1~2cmであった)上を、上記溝置装置を引いてローラーが田面を平準化した後に、作溝装置で作成した幅2cm及び深さ2cmの溝の底部に苗紐を定置した(溝置したともいう)。試験Aと比較して溝の崩壊(土の戻り)が速く、苗紐が土中に埋没し又は水中に浮遊したものがあった。また、溝置後の強い風雨により浮苗が頻発した。並行して鉄コーティング種子の水田表面播種による栽培(条間30cm、株間18cm、1株5~8粒撒き(4kg/10アール))、慣行稚苗移植栽培(条間30cm、株間18cm、1株4~7本)を行った。溝置、播種又は移植後は通常の栽培管理(苗紐及び慣行稚苗移植苗には溝置/移植後2日目に一発かんた君(15-15-15-4)(25kg/10アール)を、43日後に一発かんた君(15-15-15-4)(15kg/10アール)を施肥し、鉄コーティング栽培には側条施肥し、80日後にすべての試験区にN-K化成(15-15)(15kg/10アール)を施肥した)、一般防除(全試験区で溝置/播種/移植日にサンバード粒剤(3kg/10アール)、13日後に忍フロアブル(500ml/10アール)を施用し、鉄コーティング種子は種子に殺虫剤を施用し、苗紐と慣行稚苗移植苗には溝置/移植日にトレボン粒剤(3kg/10アール)を水面施用)をした。溝置/播種/移植日から冠根数の測定、23日目に苗立ち数の調査、生育程度の調査及び倒伏程度の調査は随時行った。溝置/播種/移植から約7か月後に収量の調査を行った。
各調査項目の評価方法は以下のとおりである。

プランター(縦27cm、横17cm、高さ10cm)の高さ5cmまで水田土壌を満たし、10cm間隔で縦方向に幅2cm深さ2cmの溝を掘り、底部に苗紐を定置した。プランターを、水を張った直径50cmのタライの中心部に置き、ネットゲージで覆った。苗紐定置17日後にヒメトビウンカ(採取したもの)雌成虫10頭+雄成虫5頭を各試験区に接種し、接種後31日目に寄生幼虫数及び寄生成虫数を計測した。
殺虫効果試験1に記載の方法に準じて、無処理、種子コーティング、浸漬処理区の苗紐を溝置して、58日後茎葉部を採取し、7cmにカットしてシャーレに入れ、ニカメイチュウ(感受性系統)2齢幼虫をシャーレあたり10頭接種した。接種6日後の生存する幼虫数を計測した。

催芽籾と緑化針苗の植付深度の許容性を比較する為に人工的に還元状態の水田条件を作り、その条件下で土壌表面、土壌表面下1cm、土壌表面下3cmの位置に植え付けたときの苗立ちを比較した。乾燥し篩にかけた水田土壌1.3kgあたりに2gの米ぬかを添加し、プラスチック容器内で代掻きし、3日温室に静置した。この容器に所定の土壌深度に鳩胸状態の催芽籾あるいは1.3葉期の緑化針苗を1容器当たり30粒播種あるいは定植した。播種・定植14日後に土壌表面から出現している芽の数(発芽数)を計測した。結果を表10に示す。
1.3葉期の緑化針苗を湿った状態でビニール袋に密封し、10℃で保存した。25日の保存後に、定植2日前に水田土壌を入れて代掻きをしていた容器内に150粒を土壌深度1cmに定植した。定植2週間後にすべての苗が健全に生育していることを確認した。
