Abstract
Description
本発明は芋の栽培における施肥方法に関する。 The present invention relates to a fertilization method in cultivation of straw.
水稲栽培は機械化が進み、一般的には生産規模の拡大による収益性向上を目指している。対して、野菜生産においては、水稲栽培ほどの機械化が進んでおらず、収益性向上は主として単位面積当たりの収量の向上に向けられている。
単位面積当たりの収量を向上させることを目的として、作物毎に適切な栽培方法（土壌、温度、肥料、栽培器具等）が種々検討されている。例えば、特許文献１には特別な栽培器具を用いた山の芋を栽培方法が記載され、特許文献２にはジベレリン生合成阻害型植物生長調節剤を用いたサツマイモの増収方法が記載されている。
近年の作物生産において行われた肥料技術の改良の成果として、肥料成分を含有する粒状物を樹脂等で被覆した、所謂被覆粒状肥料が挙げられる。被覆粒状肥料はこれまで知られていた緩効性肥料よりも、肥効期間の調節がより自由に行えるようになり、施肥回数を軽減できる長所を有するものであった。
Paddy rice cultivation is becoming more mechanized and generally aims to improve profitability by expanding production scale. On the other hand, in medicinal production, mechanization is not progressing as much as paddy rice cultivation, and profitability improvement is mainly aimed at improving yield per unit area.
In order to improve the yield per unit area, various cultivation methods (soil, temperature, fertilizer, cultivation tools, etc.) appropriate for each crop have been studied. For example, Patent Document 1 describes a method for cultivating mountain straw using a special cultivation instrument, and Patent Document 2 describes a method for increasing sweet potato yield using a gibberellin biosynthesis-inhibiting plant growth regulator.
As a result of the improvement of the fertilizer technology performed in recent crop production, a so-called coated granular fertilizer in which a granular material containing a fertilizer component is coated with a resin or the like can be mentioned. The coated granular fertilizer has the advantage that the duration of fertilization can be adjusted more freely and the number of times of fertilization can be reduced than the slow-release fertilizer known so far.
本発明は、単位面積当りの芋の収量を増加させる、芋の栽培における施肥方法を提供することを課題とする。 This invention makes it a subject to provide the fertilization method in cultivation of a cocoon which increases the yield of the cocoon per unit area.
かかる状況下において、本発明者は芋の栽培における施肥方法について、鋭意検討を重ねた結果、肥料成分のうちの窒素肥料成分及び加里肥料成分を特定の方法で施用することにより、単位面積当りの芋の収量が増加し、更には収穫される芋の形状が良好となるという副次的な効果を有することを見出し、本発明に至った。 Under such circumstances, the present inventor conducted extensive studies on fertilization methods in the cultivation of persimmons, and as a result, by applying nitrogen fertilizer components and kari fertilizer components among the fertilizer components in a specific manner, The present inventors have found that it has a secondary effect that the yield of straw is increased and the shape of the harvested straw is good, and the present invention has been achieved.

次に、本発明を詳しく説明する。
本発明における芋とは、デンプン質を蓄えて肥大化した食用となる地下茎または根を有する作物であり、例えばナガイモ、イチョウイモ、ヤマトイモ、サツマイモ、ジャガイモ、サトイモ等が挙げられる。肥大化した地下茎または根の部分が芋である。
ナガイモ、サツマイモ等のように全体の形状が細長い芋において芋の形状が良好であるとは、芋の長さに対して十分な太さを有するもの、或いは曲がりの少ない形状であることを意味する。全体の形状が細長い芋において、形状が良好であることを数値的に表わす方法としては、例えば芋の単位長さに対する重量（以下、形状指数と記す。）を用いることができる。また、ジャガイモ、サトイモ等のように全体の形状が丸い芋において芋の形状が良好であるとは、表面の凹凸が少ないか、１個当たりの重さが重いことを意味する。同様に形状指数により、形状が良好であることを数値的に表わすことが可能である。
Next, the present invention will be described in detail.
The cocoon in the present invention is a crop having an underground stalk or root that is edible by storing starchy material, and examples thereof include potato, ginkgo biloba, yam potato, sweet potato, potato, and taro. The enlarged rhizome or root is a cocoon.
When the overall shape of the cocoon is long, such as a yam, sweet potato, etc., the cocoon shape being good means that the cocoon has a sufficient thickness with respect to the length of the cocoon or a shape with little bending. . As a method for numerically representing that the shape is good in the case where the overall shape is long and narrow, for example, the weight with respect to the unit length of the ridge (hereinafter referred to as shape index) can be used. In addition, when the overall shape of a potato, such as potato or taro, the shape of the ridge is good means that there are few surface irregularities or the weight per piece is heavy. Similarly, the shape index can numerically represent that the shape is good.
野菜等の作物においては、大きさ（重量）、形状などによる出荷規格があるが、例えばナガイモでは、大きさ（重量）の区分は一般に階級と言われ、２００ｇ刻みで小さい物から、Ｓ、Ｍ、Ｌ、２Ｌ等の階級に分類されている。Ｓ以下の階級の小さな芋は廃棄されるか、極めて安い価格で取引されるし、長さに対して十分な太さの無い芋は出荷用の箱に納まりきらずに、出荷が困難になる場合がある。出荷規格内の大きさ（重量）や形状の芋を生産することも、収量とともに重要である。 For crops such as vegetables, there are shipping standards depending on size (weight), shape, etc. For example, in Chinese yam, the classification of size (weight) is generally referred to as a class. , L, 2L, etc. Small cocoons of rank S or lower are discarded or traded at an extremely cheap price, and cocoons that are not thick enough for the length do not fit in the shipping box, making shipping difficult There is.

以下、本発明の方法を、青森県地区におけるナガイモの栽培を例として以下に詳しく説明する。
まず、ナガイモの植付け前の４月から５月にかけて圃場の耕起を行う。この際、通常は堆肥を全面施用し、土壌の状態に応じて土壌改良剤（例えば石灰、苦土炭酸カルシウム）を施用する。施用される堆肥の量は、通常１０ａ当り１〜４ｔ程度である。尚、圃場の耕起には、通常溝堀り機（トレンチャー）を使用して、幅約１５ｃｍ、深さ約１ｍ、即ち収穫されるナガイモに対して十分の深さまで耕起する。
Hereinafter, the method of the present invention will be described in detail below, taking as an example the cultivation of Chinese yam in Aomori Prefecture.
First, the field is plowed from April to May before planting the yams. At this time, generally, compost is applied over the entire surface, and a soil conditioner (eg, lime, calcium carbonate) is applied according to the state of the soil. The amount of compost to be applied is usually about 1 to 4 t per 10a. In addition, the plowing of the field is usually carried out using a trenching machine (trencher) to a width of about 15 cm and a depth of about 1 m, that is, a depth sufficient for a harvested Chinese yam.
次に、５月から６月にかけて種芋の植付けを行う。種芋には、むかご、一年子、２年子、切り芋等が使用することができる。好ましくは、ウイルス病徴のない植物体から採取された種芋を用いる。
通常の畝幅は１１０〜１２０ｃｍ、株間は１８〜２４ｃｍで、１０ａ当り４０００〜５０００本程度の植付けを行う。
元肥施用にて施肥される本被覆窒素肥料は、種芋の植付けの前でも後でもよいが、通常は種芋の植付け後の約１ヶ月前後に行われる。ナガイモ元肥施用により施肥される本被覆窒素肥料は、窒素肥料成分として通常１０ａ当り１０〜２０ｋｇである。この他に速効性の窒素を成分として５〜１０ｋｇ、燐酸肥料成分として２０〜８０ｋｇ、加里肥料成分として５〜２０ｋｇを通常施用する。
Next, planting seeds from May to June. As seed potatoes, mukago, first-year children, second-year children, chopped rice cakes, etc. can be used. Preferably, seed culm collected from a plant body free from viral symptoms is used.
The normal ridge width is 110 to 120 cm, and between the strains is 18 to 24 cm, and about 4000 to 5000 plants are planted per 10a.
The present coated nitrogen fertilizer to be fertilized in the original fertilizer application may be before or after seed planting, but is usually performed about one month after seed planting. The present coated nitrogen fertilizer to be fertilized by applying Nagai fertilizer is usually 10 to 20 kg per 10a as a nitrogen fertilizer component. In addition to this, 5 to 10 kg of quick-acting nitrogen as a component, 20 to 80 kg as a phosphate fertilizer component, and 5 to 20 kg as a potassium fertilizer component are usually applied.
ナガイモは６月から７月にかけての茎葉伸長期、７月から８月にかけての茎葉繁茂期を迎えるが、茎葉伸長期において新芋が形成され、茎葉繁茂期に芋は生長肥大する。ナガイモの育成においては、必要により圃場をマルチ被覆し、茎葉が伸長し始めた頃に、蔓を巻きつかせるようにネット等を設置する。また、この時期に必要により、殺虫剤、殺菌剤等を散布する。
慣行の施肥体系においては、７月から９月にかけて１〜４回の窒素肥料の追肥が行われる。本発明の方法においては、通常は茎葉伸長期から茎葉繁茂期において、１〜４回の本速効性加里肥料を追肥施用する。ナガイモの育成においては、本速効性加里肥料における加里肥料成分の量は、通常１０ａ当り５〜３０ｋｇである。
茎葉繁茂期の後期、９月以降にかけて、芋は成熟期を迎える。この時期における芋の生長により、収穫時の芋の大きさや形状がほぼ決定される。その後、１０月から１１月にかけて茎葉黄変期を迎えた後、芋を収穫する。
Chinese yam reaches the foliage growth period from June to July, and the foliage growth period from July to August. New foliage is formed in the foliage growth period, and the buds grow and grow during the foliage growth period. In growing yams, if necessary, the field is multi-covered and a net or the like is installed so that the vines can be wrapped around when the foliage begins to grow. If necessary, spray insecticides, fungicides, etc. at this time.
In the conventional fertilization system, nitrogen fertilizer is additionally fertilized 1 to 4 times from July to September. In the method of the present invention, usually, from 1 to 4 times, this fast-acting potato fertilizer is additionally fertilized during the foliage growth period to the foliage growth period. In the cultivation of Chinese yam, the amount of kari fertilizer component in this fast-acting potato fertilizer is usually 5 to 30 kg per 10a.
The buds reach maturity during the late stem and leaf growth period and after September. The size and shape of the cocoon at the time of harvest are almost determined by the growth of the cocoon at this time. After that, from October to November, the stems and leaves turn yellow.
以下、実施例により本発明をさらに具体的に説明するが、本発明はこれらに限定されるものではない。
