Description
本発明は、茎菜類(アスパラガス、等)、根菜類(ジャガイモ、サツマイモ、ショウガ、等)、菜豆類(大豆、小豆、等)、落葉果樹(ブドウやイチジク、等)の糖度又は収量を増加させる方法に関する。 The present invention relates to the sugar content or yield of stem vegetables (asparagus, etc.), root vegetables (potato, sweet potato, ginger, etc.), vegetable beans (soybeans, red beans, etc.), and deciduous fruit trees (grape, figs, etc.). It relates to how to increase.
茎菜類のアスパラガスを例に取ると、4月中旬から9月頃まで芽が出て採取できるが、それ以後は休眠期にはいる。従来我が国では、アスパラガスの産地は北海道、長野地方を始めとする冷涼地域であったが、近年需要の拡大や栽培技術の向上により、2月、3月に早出し、秋までに長期間収穫することを目指して西日本での生産が行われている。 Taking asparagus, an example of stem vegetables, buds can be collected from mid-April to September, but after that it is in the dormant period. Traditionally, in Japan, asparagus was produced in cool areas such as Hokkaido and Nagano, but in recent years, due to growing demand and improvements in cultivation techniques, it started early in February and March, and harvested for a long time by autumn. Production is being done in western Japan with the aim of doing this.
しかし、アスパラガスは正常な生育のためには一定期間の休眠は必須であるにも関わらず、近年の暖冬化現象により、早出し栽培では十分な休眠時間が得られないので、大幅な収量低下や品質の低下が起こることがある。 However, asparagus must be dormant for a certain period for normal growth, but due to the recent warm winter phenomenon, sufficient dormancy time cannot be obtained in early-stage cultivation, resulting in a significant drop in yield. Or quality degradation may occur.
この問題を解決するため、下記特許文献1では、メチオニンをアスパラガスが栽培されている畑地に施用することを特徴とするアスパラガスの栽培方法が提案されている。
特許文献1によれば、メチオニンは、単独で又は必要に応じて適当な担体と混合して施用してもよく、或いは土壌に施用される肥料混合物に含ましめて施用することも可能である。施用量は0.5kg/10a(培地)〜 50kg/10a(培地)である。「メチオニンの施用量が、この範囲以下に少量の場合には効果が少なく実用的とは言い難い」(第2頁右上欄10−12行)と記載されている。 According to Patent Document 1, methionine may be applied alone or in combination with an appropriate carrier as necessary, or may be applied in a fertilizer mixture applied to soil. The application rate is 0.5 kg / 10a (medium) to 50 kg / 10a (medium). “If the amount of methionine applied is less than this range, the effect is small and it is difficult to say that it is practical” (page 2, upper right column, lines 10-12).
本発明は、上記範囲よりも遙かに少ない施用量のメチオニンを葉面散布することにより、収量の増大や糖度の向上に成功したものである。 The present invention has succeeded in increasing yield and improving sugar content by foliar application of methionine at a much lower application rate than the above range.
本発明は、アスパラガスに対して、60g/10a〜 100g/10aのメチオニンを葉面散布により施用することを特徴とする、アスパラガスの貯蔵根糖度を高める方法である。
The present invention is, with respect to asparagus, which comprises applying a methionine 60g / 10a~ 100g / 10a by foliar application, a method of increasing the storage root sugar degree of asparagus.
後記実験結果に記すように、本発明を早出し栽培のアスパラガスについて実施したところ、屈折糖度計による貯蔵根の糖度計測で従来20〜23%程度であった糖度が30%近くまで改善された。貯蔵根の糖度の理想は30%以上といわれるから、それにはやや届かなかったが、従来の栽培方法と比べると大幅な向上である。一般的な概算収量方程式(糖度×親株茎数×株重×株数)のうち、糖度以外は事前に決定されているので、糖度向上は収量増大に直結するのが明らかである。 As described later in the experimental results, when the present invention was carried out for asparagus grown early, the sugar content of the storage root measured by a refractometer was improved from about 20 to 23% to nearly 30%. . It is said that the ideal sugar content of stored roots is 30% or more, so it did not reach this level, but it is a significant improvement compared to conventional cultivation methods. Of the general approximate yield equation (sugar content × number of parental stems × strain weight × number of strains), it is clear that an increase in sugar content is directly linked to an increase in yield, except for the sugar content.
本発明が適用される茎菜類は、アスパラガス、等であり、根菜類は、ジャガイモ、サツマイモ、ショウガ、等であり、菜豆類は、大豆、小豆、等であり、落葉果樹は、ブドウやイチジク、等である。作物や品種によって効果に差があるものと推測されるが、全作物の全品種に適用可能である。 Stem vegetables to which the present invention is applied are asparagus, etc., root vegetables are potato, sweet potato, ginger, etc., vegetable beans are soybeans, red beans, etc., deciduous fruit trees are grapes and Fig, etc. It is estimated that there is a difference in effect depending on crops and varieties, but it is applicable to all varieties of all crops.
本発明に用いられるメチオニンは公知の方法によって工業的に製造されているものが用いられる。例えば、日本曹達株式会社製造の「DL−メチオニン」又は「L−メチオニン」を使用することができる。メチオニンが人畜に無害であることは、これが飼料添加物として広く使用され、かつ必須アミノ酸であることから明らかである。 As the methionine used in the present invention, those produced industrially by a known method are used. For example, “DL-methionine” or “L-methionine” manufactured by Nippon Soda Co., Ltd. can be used. It is clear that methionine is harmless to humans because it is widely used as a feed additive and is an essential amino acid.
実際には、前記「日本曹達DL−メチオニン」の場合、水で3000倍に稀釈して、10aの培地当たり150リットル〜250リットルの水溶液を葉面に対してスプレー散布する。その際、展着剤は必ずしも必要としない。散布頻度は、収穫の3〜5週間前に1回〜3回行うのが好ましい。 Actually, in the case of the “Nippon Soda DL-methionine”, it is diluted 3000 times with water and sprayed with 150 to 250 liters of aqueous solution per 10a medium on the leaf surface. At that time, a spreading agent is not necessarily required. The application frequency is preferably 1 to 3 times 3 to 5 weeks before harvesting.
以下、実施例により本発明を説明するが、本発明はこの実施例によって限定されるものではない。 EXAMPLES Hereinafter, although an Example demonstrates this invention, this invention is not limited by this Example.
雨よけハウスにおけるアスパラガス栽培では高い生産技術を持つ佐賀県三養其郡三根町において次の4つに実験区を分けて実験した。 In asparagus cultivation in the rain-proof house, the experiment was divided into the following four areas in Sane-cho, Sanyoso-gun, Saga Prefecture, which has high production technology.

実験方法
2004年11月25日に各4区10株のアスパラガスの株元を小型スコップで掘り、貯蔵根を5〜6g切り取り、すりつぶして、屈折糖度計(Atago Hand Refractometer No. 11832 Brix− 0〜32%)で糖度を測定し、10株の平均を算出した。
experimental method
On November 25, 2004, each of the four districts of 10 asparagus stocks was dug with a small scoop, 5 to 6 g of the storage root was cut and ground, and the refraction sugar meter (Atago Hand Refractometer No. 11832 Brix-0 to 32 %), The sugar content was measured, and the average of 10 strains was calculated.
その後、同日に、上記3種類の水溶液と対照区として水を各区のアスパラガスの地上茎葉に葉面散布した。各区は、間口6m長さ50mのハウスを用い、1区10mとし、各区の間には干渉を避けるため3m程度あけた。 Thereafter, on the same day, water was sprayed onto the above-mentioned ground foliage of asparagus in each of the three types of aqueous solutions and the control group. Each ward uses a house with a frontage of 6m and a length of 50m. Each ward has a length of 10m, with a space of about 3m between each ward to avoid interference.
2回目の採取・糖度測定と各区の葉面散布は2004年12月2日に行われた。 The second sampling, sugar content measurement and foliar spraying of each group were carried out on December 2, 2004.
3回目以降は、2004年12月9日、12月16日、12月23日、12月31日に行われたが、各区の葉面散布は行わず、採取・糖度測定のみを行った。 The third and subsequent tests were conducted on December 9, 2004, December 16, December 23, and December 31, but no foliar spraying was performed on each section, and only sampling and sugar content measurement were performed.
結果は下記表2及び添付の図1に示すとおりである。
この図より、メチオニン水溶液を葉面散布したアスパラガスの糖度が、対照区の水区では24%程度であったのが27.1%まで改善されているの分かる。ミラクルアミン水溶液を使用したものも25.9%に向上しているが、この差は誤差の範囲であり、メチオニンの有効性に変わりがない。 From this figure, it can be seen that the sugar content of the asparagus sprayed with a methionine aqueous solution on the foliage has been improved from about 24% in the control section to 27.1%. The one using miracleamine aqueous solution also improved to 25.9%, but this difference is within the error range, and the effectiveness of methionine remains unchanged.
