【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、植物の生育に用いられる液状肥料又は培養
液に関する。Description: TECHNICAL FIELD The present invention relates to a liquid fertilizer or a culture solution used for growing plants.
近年、農業の近代化に伴い、水耕栽培、ロックウール
栽培等の新しい養液栽培と呼ばれる施設園芸が普及しつ
つある。In recent years, with the modernization of agriculture, facility horticulture called new hydroponic cultivation such as hydroponics and rock wool cultivation is becoming widespread.
これらの栽培方法では、植物の養分は大部分を液状の
溶液として根から吸収させている。In these cultivation methods, most of the nutrients of the plant are absorbed from the roots as a liquid solution.

で粉末から調製して混ぜ合わせていた。In conventional soil cultivation, calcium, which is an essential component, is applied to the soil in a form that is hardly soluble in water, such as masonry lime, superphosphate lime, quick lime, slaked lime, but in hydroponic cultivation in the form of an aqueous solution. Needed to supply. For this reason, conventionally, an aqueous solution of calcium nitrate was prepared from powder in situ and mixed with a nutrient solution in which other fertilizer components were dissolved.

の場で粉末から調製して葉面散布することが一般に普及
している。On the other hand, in the cultivation of tomatoes and melons, it is common practice to prepare an aqueous solution of a calcium salt such as calcium chloride or calcium formate from powder in situ and spray it onto the leaves as a measure against ass rot caused by calcium deficiency. Widespread.
これら従来からのカルシウム塩の利用方法は、いずれ
も粉末状の薬剤をその場で水に溶かして用いるようにな
っていた。In all of these conventional methods of using calcium salts, powdered drugs are dissolved in water on the spot and used.

溶性の炭酸カルシムウを生成して沈澱するなどの問題が
あったためである。This is because calcium salts have problems such as precipitation of crystals during storage in a high-concentration aqueous solution and formation of insoluble calcium carbonate by absorbing carbon dioxide gas in the air.
しかし、本来は養液栽培、葉面散布共、水溶液の形の
方が、溶解の手間が不用で、計量、希釈共に容易で好ま
しいのである。However, the form of an aqueous solution for both nutrient cultivation and foliar spraying is originally preferred because it does not require dissolving labor and is easy to measure and dilute.
