であり、植物の成長に最も重要な肥料となっている。2. Description of the Related Art Generally, when cultivating a plant, the three major components such as nitrogen (nitrogen), phosphorus, and potassium, among the components necessary for growing the plant, tend to be particularly deficient, so that they must be provided as fertilizers sufficiently. Moreover, plants obtain chisso among these three major elements from chisso compounds (chisso source) such as inorganic compounds such as nitrates and ammonium salts. This chisso is a constituent element of organic compounds such as proteins, nucleic acids, and chlorophyll that play important roles in the living body of plants, and is the most important fertilizer for plant growth.

It is used for growing leaves.
【０００４】一方、野菜の土壌栽培では、例えば連作障

野菜全体の生育が遅れたり、土壌の老朽化による収量の
低下等種々の問題がある。近年、この様な問題を解消す
る栽培方法として野菜の水耕栽培方法が着目され、種々
の装置が開発されている。On the other hand, in soil cultivation of vegetables, for example, continuous cropping failure occurs, root elongation is suppressed due to soil hardness, growth of the whole vegetables is delayed, yield deterioration due to soil deterioration, and other various causes. There's a problem. In recent years, a hydroponic cultivation method for vegetables has attracted attention as a cultivation method for solving such a problem, and various devices have been developed.
【０００５】この水耕栽培では上記三大要素や他の要素

野菜の根をこの水耕肥料溶液に浸漬して、この水耕肥料
溶液から成長に必要な成分を野菜に吸収させるようにし
ている。In this hydroponic cultivation, an aqueous solution containing the above-mentioned three major elements and inorganic salts of other elements is used as a hydroponic fertilizer solution. Then, while making the hydroponic fertilizer solution containing oxygen flow in the cultivation container (hydroponic cultivation bed),
The roots of vegetables are dipped in the hydroponic fertilizer solution so that the vegetables absorb the components necessary for growth.
【０００６】[0006]
【発明が解決しようとする課題】ところで、水耕栽培の
野菜類は土壌栽培のものに較べ、硝酸塩含有量が著しく
多い。この硝酸塩は、野菜の苦み成分となるばかりでな
く、動物生体内で発癌物質を生成するものとして、最近
大きな問題となっている。By the way, compared with soil-cultivated vegetables, hydroponic vegetables have a significantly higher nitrate content. This nitrate has become a big problem not only as a bitter ingredient of vegetables but also as a carcinogen in the living body of animals.
【０００７】この水耕栽培によって栽培された野菜のう
ち例えばホウレンソウ等の葉菜類に硝酸塩の含有量が多
い。この葉菜類に硝酸塩が多いのは水耕肥料溶液の成分
によるもので、水耕肥料溶液では土壌栽培肥料に較べア
ンモニア態窒素に対する硝酸窒素の比率が多いためであ
る。Among vegetables cultivated by the hydroponic culture, leaf vegetables such as spinach have a high content of nitrates. The reason why the leaf vegetables have a large amount of nitrate is that they are due to the components of the hydroponic fertilizer solution, and the hydroponic fertilizer solution has a large ratio of nitrogen nitrate to ammonia nitrogen as compared to the soil fertilizer.
【０００８】また、水耕栽培の葉菜類は、土耕栽培のも
のに較べ生育が速い反面、上述のような原因により硝酸

た。特に、硝酸塩は、野菜の苦み成分となるばかりでな
く、動物生体内で発癌物質を生成するものとして最近大
きな問題となっている。Further, hydroponically grown leafy vegetables grow faster than soil-cultivated ones, but on the other hand, due to the above-mentioned causes, the content of nitrate is high and the content of water is high. Low in fiber and vitamin C. For this reason, there has been a problem that hydroponic leafy vegetables are inferior in quality such as watery, strongly bitter, less sweet, easy to break, and poor in nutrition. In particular, nitrate has become a big problem not only as a bitter ingredient of vegetables but also as a carcinogen in the living body of animals.
【０００９】これに対して、収穫前に植物への肥料溶液

無しに単に絶対量を制限するのみであったため、野菜の
生育が著しく阻害されると共に、溶液制御が難しく、
又、硝酸塩をあまり減少させることができないという問
題があった。On the other hand, methods for limiting the supply of the fertilizer solution to the plants before harvesting or giving stress to the plants such as inhibition of absorption of the fertilizer solution to improve the quality of vegetables have been proposed. Since it simply limited the absolute amount without changing the overall fertilizer component mixing ratio, it significantly hindered the growth of vegetables and made solution control difficult,
In addition, there is a problem that nitrates cannot be reduced so much.

を提供することを目的とするものである。Therefore, according to the present invention, it is possible to supply a sufficient amount of nitrate necessary for growth when growing vegetables, to sufficiently reduce the amount of nitrate when harvesting vegetables, without causing damage to the growth of vegetables. It is low in content, high in sugar, fiber and vitamin C, and watery,
An object of the present invention is to provide a method for hydroponic cultivation of vegetables, which can eliminate the causes of quality deterioration such as strong bitterness, low sweetness, easy breakage, and poor nutrition.

とする。In order to achieve this object, the present invention is to hydroponically cultivate vegetables with a hydroponic fertilizer solution containing nitrate nitrogen, to grow the vegetables to some extent, and then to add the vegetables. Remaining within the vegetables by hydroponically cultivating the vegetables with a hydroponic fertilizer solution having little or no nitrate nitrogen content for 2 days to several days within a certain period before harvesting The method is characterized in that a method of hydroponics of vegetables is further cultivated for one day or more after consuming most of the nitrate nitrogen.

Use until the vegetables have almost no nitrate content. Moreover, hydroponics is carried out as it is for one day or more from the time when the content of nitrate is almost exhausted. The fixed period does not necessarily have to be 2 weeks, and may be longer or shorter than 2 weeks depending on the type of vegetables.

Very low content of crystalline nitrogen. As a result, in the latter stage of growth, the vegetables 4 make amino acids based on the nitrate nitrogen taken into the body in the earlier stage of growth and utilize them for the growth of roots, stems, leaves and the like. That is, it grows while consuming the nitrate nitrogen in the vegetables, and consumes most of the nitrate nitrogen in the body at the time of harvesting the vegetables. In this way, even if the content of nitrate nitrogen is made small in the latter stage of growth, the nitrate in the vegetable body can be remarkably reduced without causing physiological damage to the vegetable 4.

During the week, when the second solution of (2) was grown for 7 days, the result as shown after the treatment of (b) of (3) was obtained. still,
Before (a) treatment in (3), the case where only the first solution in (1) is grown is shown.

By hydroponically cultivating the vegetables with a hydroponic fertilizer solution having little or no nitrate nitrogen content for 2 to several days, most of the nitrate nitrogen remaining inside the vegetables is consumed. After that, since the cultivation is continued for more than one day, it is possible to sufficiently supply the nitrates necessary for the growth of the vegetables without causing the growth failure of the vegetables. Moreover, by such cultivation, it is possible to reduce the water content and increase the sugar, fiber and vitamin C.
