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.

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 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

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.

【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

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】そこで、この発明は、野菜の成長時には生
育に必要な硝酸塩を充分に供給でき、野菜の収穫時には
硝酸塩を充分に低下させることができる水耕栽培方法を
提供することを目的とするものである。[0008] Therefore, an object of the present invention is to provide a hydroponic cultivation method capable of supplying a sufficient amount of nitrate necessary for growth when growing vegetables, and sufficiently reducing nitrate when harvesting vegetables. Is.

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.
