JP 2004-051434 A Japanese Patent Laid-Open No. 2001-240483

家庭園芸向けに販売されている希釈タイプの高濃度液体肥料は、製剤全体に対する窒素成分(Nとして)−リン成分(Pとして)−カリウム成分(KOとして)の割合が5(質量%)−10(質量%)−5(質量%)、あるいは6(質量%)−10(質量%)−5(質量%)等、リン成分が窒素、あるいはカリウムに対し多い場合が多い。これは、従来窒素量を増大させた複合肥料を散布した植物の花数は一般的に減少すると考えられたためである。しかし、本発明者らは実験を繰り返した結果、このような従来知識は必ずしも正しくなく、窒素成分添加濃度は植物の生育に影響が大きく、液体肥料を同倍率で希釈した場合に窒素成分添加濃度が高濃度であるほど植物の生育が良く、一方、リン成分は、必要以上に高濃度であっても一般植物の生育はあまり向上しないことを知見した。すなわち窒素の含量を増大させると共にリン含量を減少させた肥料は植物の生育を促進するのみならず、植物体の花数を増大させ得るとの驚くべき新知見を得た。
比較的高濃度の窒素成分、リン成分、カリウム成分を含み、その他にマグネシウム、マンガン、ホウ素、鉄、カルシウム、銅、亜鉛、モリブデン等の微量金属元素を添加した希釈タイプの高濃度液体肥料は、経時変化や紫外線暴露、あるいは低温時に結晶、沈殿を生じやすく、そのため液体肥料としての効力が低下するという問題があった。そこで、本発明は、製剤的に長期保存に対して安定な希釈タイプの高濃度液体肥料組成物(以下、単に液体肥料組成物ともいう。)、特に、高濃度の3大栄養素、肥料保証成分および微量金属元素を含有する使用時水で希釈するタイプの液体肥料組成物であって、経時的な変化、または紫外線暴露下や低温時に結晶や沈殿の生成が抑制された新規液体肥料組成物を提供することをも目的とする。
The dilution type high-concentration liquid fertilizer sold for home gardening has a ratio of nitrogen component (as N) -phosphorus component (as P 2 O 5 ) -potassium component (as K 2 O) to 5 ( In many cases, the phosphorus component is larger than nitrogen or potassium, such as (mass%)-10 (mass%)-5 (mass%), or 6 (mass%)-10 (mass%)-5 (mass%). This is because the number of flowers that have been sprayed with a complex fertilizer with an increased amount of nitrogen is generally considered to decrease. However, as a result of repeating experiments, the present inventors have found that such conventional knowledge is not always correct, and the concentration of nitrogen component addition has a large effect on the growth of plants, and the concentration of nitrogen component addition when liquid fertilizer is diluted at the same magnification It has been found that the higher the concentration of, the better the growth of the plant, while the phosphorus component does not significantly improve the growth of general plants even when the concentration is higher than necessary. That is, a surprising new finding has been obtained that a fertilizer having an increased nitrogen content and a reduced phosphorus content not only promotes the growth of the plant but also increases the number of flowers of the plant body.
Diluted type high-concentration liquid fertilizer containing a relatively high concentration of nitrogen, phosphorus, potassium, and other trace metal elements such as magnesium, manganese, boron, iron, calcium, copper, zinc, molybdenum, There was a problem that crystallization and precipitation were likely to occur at the time of change, exposure to ultraviolet rays, or low temperature, and therefore the effectiveness as a liquid fertilizer was reduced. Therefore, the present invention is a diluted high-concentration liquid fertilizer composition (hereinafter also simply referred to as a liquid fertilizer composition) that is stable for long-term storage in terms of formulation, and in particular, high-concentration three major nutrients and fertilizer assurance components. A new type of liquid fertilizer composition that is diluted with water when used and contains trace amounts of metal elements, and which suppresses the formation of crystals and precipitates under time-dependent changes or exposure to ultraviolet light or at low temperatures. It is also intended to provide.

本発明者らは、上記課題を解決するため鋭意研究を行い、下記[1]の解決手段により上記課題が解決され得ること、さらには植物の3大栄養素のうち窒素量、特に硝酸態窒素量とアンモニア態窒素量の調節、リン量の調整、pHの調整、肥料保証成分の配合量および微量金属元素の添加量並びにキレート剤の選択とその添加量の調節により上記課題を特に有利に解決できることを見出し、さらに検討を重ねて本発明を完成した。   The present inventors have intensively studied to solve the above-mentioned problems, and that the above-mentioned problems can be solved by means for solving the following [1]. Further, among the three major nutrients of plants, the amount of nitrogen, particularly the amount of nitrate nitrogen The above problems can be solved particularly advantageously by adjusting the amount of ammonia nitrogen, adjusting the amount of phosphorus, adjusting the pH, adding the fertilizer guarantee component, adding the trace metal element, and selecting the chelating agent and adjusting the added amount. As a result, the present invention was completed.

本明細書において、「肥料」とは、植物に養分(元素)を与えるために、植物の例えば葉や茎または根、あるいは植物育成用養液若しくは植物育成用培土に施す物質のことをいう。植物の生育に必要な養分(元素)は、10数種類あるが、そのうち、大量に補給を要する元素は、窒素、リンおよびカリウムの3大栄養素で、次いでマグネシウム、マンガンおよびホウ素等の肥料保証成分、並びにカルシウム、鉄、銅、亜鉛およびモリブデン等の微量金属元素等である。
「高濃度液体肥料」とは、水等の溶媒に前記元素が高濃度に溶解している肥料をいい、特に窒素、リンおよびカリウムの合計量が約19.5質量%以上水等の溶媒に溶解している肥料をいう。
In this specification, “fertilizer” refers to a substance applied to a plant, for example, a leaf, a stem, or a root, or a plant-growing nutrient solution or a plant-growing soil to provide nutrients (elements) to the plant. There are more than 10 types of nutrients (elements) necessary for plant growth. Among them, the elements that need to be replenished in large quantities are the three major nutrients, nitrogen, phosphorus and potassium, followed by fertilizer guaranteeing components such as magnesium, manganese and boron, And trace metal elements such as calcium, iron, copper, zinc and molybdenum.
“High-concentration liquid fertilizer” refers to a fertilizer in which the above elements are dissolved in a high concentration in a solvent such as water. In particular, the total amount of nitrogen, phosphorus and potassium is about 19.5 mass% or more in a solvent such as water. Refers to dissolved fertilizer.

上記肥料の3大栄養素のうち窒素は、タンパク質の合成、細胞の分裂、増殖、花芽形成、根の発育、養分の吸収、あるいは同化作用の促進に必要な元素である、窒素としては、硝酸態窒素、アンモニア態窒素および尿素態窒素等が挙げられる。   Among the three major nutrients of the fertilizer, nitrogen is an element necessary for protein synthesis, cell division, proliferation, flower bud formation, root development, nutrient absorption, or promotion of anabolism. Nitrogen, ammonia nitrogen, urea nitrogen and the like can be mentioned.

硝酸態窒素とは、硝酸イオンのように酸化窒素の形で存在する窒素のことをいう。硝酸態窒素源となりうる化合物としては、例えば硝酸、硝酸アンモニウム、硝酸カルシウム、硝酸カリウム、硝酸ナトリウム、硫硝安(硝酸アンモニウム+硫酸アンモニウム)、硝安石灰(硝酸アンモニウム+炭酸カルシウム)またはカルウレア(硝酸カルシウム+CO(NH)等が挙げられるが、これらに限定されない。これら化合物は、1種または2種以上を混合して用いることもできる。 Nitrate nitrogen refers to nitrogen that exists in the form of nitric oxide, such as nitrate ions. Examples of the compound that can be a nitrate nitrogen source include nitric acid, ammonium nitrate, calcium nitrate, potassium nitrate, sodium nitrate, ammonium nitrate (ammonium nitrate + ammonium sulfate), ammonium nitrate lime (ammonium nitrate + calcium carbonate), or calurea (calcium nitrate + CO (NH 2 ) 2 ) And the like, but is not limited thereto. These compounds may be used alone or in combination of two or more.

アンモニア態窒素とは、アンモニア水、アンモニウム塩、アンモニウムイオンを構成する窒素のこという。アンモニア態窒素源となりうる化合物としては、例えば硫酸アンモニウム、塩化アンモニウム、硝酸アンモニウム、第一リン酸アンモニウム、第二リン酸アンモニウム、水酸化アンモニウム、ホウ酸アンモニウム、硫硝安(硝酸アンモニウム+硫酸アンモニウム)またはアンモホス(硫酸アンモニウム+第二リン酸アンモニウム)等が挙げられるが、これらに限定されない。これら化合物は、1種または2種以上を混合して用いることもできる。   Ammonia nitrogen means nitrogen constituting ammonia water, ammonium salt, and ammonium ion. Examples of the compound that can be an ammonia nitrogen source include ammonium sulfate, ammonium chloride, ammonium nitrate, primary ammonium phosphate, secondary ammonium phosphate, ammonium hydroxide, ammonium borate, ammonium sulfate (ammonium nitrate + ammonium sulfate) or ammophos (ammonium sulfate + Dimmonium phosphate) and the like, but is not limited thereto. These compounds may be used alone or in combination of two or more.

尿素態窒素とは、尿素や加水分解により尿素になりうる窒素をいう。尿素態窒素源となりうる化合物としては、尿素、カルウレア(尿素+硝酸カルシウム)またはカルシウムシアナミドが挙げられるが、これらに限定されない。これら化合物は、1種または2種以上を混合して用いることもできる。   Urea nitrogen refers to urea or nitrogen that can be converted to urea by hydrolysis. Compounds that can serve as a urea nitrogen source include, but are not limited to, urea, calurea (urea + calcium nitrate), or calcium cyanamide. These compounds may be used alone or in combination of two or more.

本発明における窒素量は、硝酸態窒素、アンモニア態窒素および尿素態窒素(Nとして)の合計量として、組成物全体に対し約7.5質量%以上、好ましくは約7.5質量%以上約9.0質量%以下、さらに好ましくは約7.5〜8.5質量%程度である。
硝酸態窒素、アンモニア態窒素および尿素態窒素の含有比率に特に制限はないが、硝酸態窒素1質量部に対して、アンモニア態窒素が約3〜4.5質量部、尿素態窒素が約2.4〜3質量部程度が好ましい。
なお、硝酸態窒素の含有比率が大きいと、寒冷地等の低温(約−30〜4℃程度)環境下によっては例えば硝酸カリウム等の化合物の結晶が析出することがある。このため、組成物全体に対する硝酸態窒素(Nとして)は約0.5質量%以上約1.5質量%未満(例えば、硝酸カリウムの量として、約36.1g/Kg以上、約108.3g/Kg未満である。)、好ましくは約0.9〜1.3質量%とするのが好ましい。
アンモニア態窒素は、尿素態窒素に比べ速効性窒素形態であるので、尿素態窒素より含有比率が高い方が好ましい。しかし、アンモニア態窒素の含有量が高くなりすぎると、液体肥料組成物のpHが高くなりすぎ、安定性が悪くなる。このため、アンモニア態窒素(Nとして)は、組成物全体に対して約1.5〜6.75質量%とし、好ましくは約3.3〜4.8質量%とするのが好ましい。
尿素態窒素は、硝酸態窒素およびアンモニア態窒素の量並びに窒素の合計量から換算して組成物全体に対して約1.2〜4.5質量%が好ましく、約2.3〜3.5質量%がより好ましい。
The amount of nitrogen in the present invention is about 7.5% by mass or more, preferably about 7.5% by mass or more and about 7.5% by mass or more, based on the total composition, as the total amount of nitrate nitrogen, ammonia nitrogen and urea nitrogen (as N). It is 9.0 mass% or less, More preferably, it is about 7.5-8.5 mass%.
The content ratio of nitrate nitrogen, ammonia nitrogen and urea nitrogen is not particularly limited, but ammonia nitrogen is about 3 to 4.5 parts by mass and urea nitrogen is about 2 with respect to 1 part by mass of nitrate nitrogen. About 4 to 3 parts by mass is preferable.
In addition, when the content ratio of nitrate nitrogen is large, a crystal of a compound such as potassium nitrate may be precipitated depending on a low temperature (about −30 to 4 ° C.) environment such as a cold district. For this reason, nitrate nitrogen (as N) based on the whole composition is about 0.5 mass% or more and less than about 1.5 mass% (for example, the amount of potassium nitrate is about 36.1 g / Kg or more, about 108.3 g / Less than Kg.), Preferably about 0.9 to 1.3% by weight.
Since ammonia nitrogen is in a fast acting nitrogen form compared to urea nitrogen, it is preferable that the content ratio is higher than that of urea nitrogen. However, if the content of ammonia nitrogen becomes too high, the pH of the liquid fertilizer composition becomes too high and the stability becomes poor. For this reason, ammonia nitrogen (as N) is about 1.5 to 6.75 mass%, preferably about 3.3 to 4.8 mass%, based on the entire composition.
The urea nitrogen is preferably about 1.2 to 4.5% by mass based on the total amount of nitrate nitrogen and ammonia nitrogen and the total amount of nitrogen, preferably about 2.3 to 3.5. The mass% is more preferable.

本発明の液体肥料組成物には、上記の他、窒素として、例えばアミノ酸態窒素やタンパク質態窒素等を含有してもよい。   In addition to the above, the liquid fertilizer composition of the present invention may contain, for example, amino nitrogen or protein nitrogen as nitrogen.
