本発明は液体肥料に関し、極めて溶液安定性の高い液体
肥料を提供することを目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid fertilizer, and an object of the present invention is to provide a liquid fertilizer with extremely high solution stability.
近年、施設園芸や、園芸作物の栽培が普及し、省力で合
理的施肥に適する液体肥料への期待は益々高まっている
。液体肥料はこれまで、肥料３要素を主体に、各種各様
のものが開発され、徴量要素を含む葵面散布用液体肥料

散布機等の目詰を起こす等の問題を内在していた。In recent years, greenhouse horticulture and the cultivation of horticultural crops have become widespread, and expectations are increasing for liquid fertilizers that are labor-saving and suitable for rational fertilization. Various types of liquid fertilizers have been developed so far, mainly containing the three fertilizer elements, and liquid fertilizers for spraying on hollyhock surfaces containing collecting elements have also been put into practical use. However, liquid fertilizers containing at least phosphoric acid, magnesium, and calcium precipitate crystalline substances during storage, resulting in the formation of crystalline substances at tank outlets, fertilizing pipes, etc.
This had inherent problems such as clogging of spreaders, etc.
この結晶性物質析出傾向は、環境温度の変化が激しい程
、また塩類濃度が高い程著しい。This tendency for crystalline substances to precipitate becomes more pronounced as the environmental temperature changes more rapidly and as the salt concentration increases.
このため、結晶性物質の析出を抑止する方法として、ク

問題点を解決すべく、種々検討を重ねた結果「りん酸、
マグネシウム、カルシウムイオンを含有せる液体肥料に
ヒドロキシ酢酸を共存せしめれば、全く結晶性物質の析
出を見ず、安定貯蔵可能なることを発見し、かかる知見
に基づき、本発明を完成したものである。For this reason, as a method to suppress the precipitation of crystalline substances, the addition of citric acid, tartaric acid, oxalic acid, acetic acid, EDTA, etc., or the use of dilute solutions, etc., have been used, but this has not sufficiently solved the problem. . Therefore, in order to solve this problem, the present inventors conducted various studies and found that ``phosphoric acid,
The inventors have discovered that if hydroxyacetic acid is made to coexist with a liquid fertilizer containing magnesium and calcium ions, stable storage is possible without any precipitation of crystalline substances.Based on this knowledge, the present invention was completed. .

に関する。That is, the first invention relates to a liquid fertilizer containing hydroxyacetic acid and at least a ion-donating substance of phosphoric acid, calcium, and magnesium, and the second invention relates to a liquid fertilizer containing hydroxyacetic acid and at least a ion-donating substance of phosphoric acid, calcium, and magnesium. Concerning liquid fertilizer made by coexisting substances.

らに限定されるものではない。Examples of the phosphate ion donating substance of the present invention include water-soluble phosphates such as pentaphosphoric acid, acidic potassium phosphate, acidic magnesium phosphate, acidic calcium phosphate, acidic ammonium phosphate, and ammonium sulfuric acid phosphate. Examples of the donor substance include water-soluble monolithic salts such as calcium chloride and calcium nitrate, and examples of the magnesium ion donor substance include water-soluble salts such as magnesium hydroxide, magnesium chloride, magnesium nitrate, and acidic magnesium phosphate. However, the flaw may be a substance that donates each ion alone or by reaction, and the present invention is not limited thereto.
本第２の発明に使用する硝酸イオン供与物質としては、
硝酸、硝酸アンモニウム、硝酸カリウム、硝酸ナトリウ
ム等の水熔性塩を例示することができる。The nitrate ion donating substance used in the second invention is as follows:
Examples include water-soluble salts such as nitric acid, ammonium nitrate, potassium nitrate, and sodium nitrate.
次に、本発明ヒドロキシ酢酸の液体肥料中の濃度に関し

重量％がよい。Next, regarding the concentration of the hydroxyacetic acid of the present invention in a liquid fertilizer, it varies depending on the concentration of salts in the liquid fertilizer and its type, the pH of the liquid fertilizer, and the environmental temperature, and cannot be determined unconditionally, but it is generally about 0.5. ~20% by weight, and the higher the salt concentration, the higher the pH, and the more severe the environmental temperature change,
Furthermore, it is desirable to use more hydroxyacetic acid as the amount of components increases. ``Although the concentration of nitrate ions in liquid fertilizer cannot be unconditionally determined as in the case of hydroxyacetic acid, it is preferably 20 to 6% by weight relative to hydroxyacetic acid.
