Description
본 발명은 비료 조성물, 그 제조 방법 및 사용 방법에 관한 것이다.The present invention relates to a fertilizer composition, a method for producing the same and a method for using the same.
일반적으로 비료로서는, 작물, 화훼류 등의 식물체의 성장에 필요한 성분을 보충하기 위해서 복수의 성분을 균형있게 배합한 복합비료가 이용된다. 고체상태인 채로 시비(施肥)하는 경우에는, 토양 중의 수분에 의해 용해되어 나오는 양분을 식물체가 이용하게 되지만, 양분의 과부족이 되거나 부분적으로 비료의 농도차이가 생겨 작물에 악영향을 주거나 염류 집적에 의한 연작 장해, 지하수 및 하천에의 비료 성분의 유출 등의 문제를 가지고 있다. 그 때문에 식물체에 필요한 성분량을 공급하기 쉬운 수용액으로 한 비료도 일반적으로 사용되고 있다. 이 비료는 액체 비료라고 칭해지고, 특히 식물체에의 시비 관리를 실시하는 양액(養液)재배법에 사용되고 있다.In general, as a fertilizer, a compound fertilizer in which a plurality of components are well-balanced is used in order to supplement the components necessary for the growth of plants such as crops and flowers. In the case of fertilizing in the solid state, the plant uses the nutrients dissolved by water in the soil, but it is caused by the lack of nutrients or partly due to the concentration difference of the fertilizer, which adversely affects crops or is caused by salt accumulation. It has problems such as serial disturbance, outflow of fertilizer components to groundwater and rivers. Therefore, the fertilizer made into the aqueous solution which is easy to supply the amount of components required for a plant is also generally used. This fertilizer is called liquid fertilizer and is especially used for the nutrient solution cultivation method which manages fertilization to a plant.
양액재배법으로서는, 자갈, 모래, 토탄(土炭), 질석(蛭石), 경석(輕石), 톱밥, 암면, 우레탄 등의 지지체에 식물체를 정식(定植)하고, 이 식물체에 액체 비료 를 공급하는 배지경법(培地耕法) 및 수경법, 토양에 정식된 작물의 근(根)권역에 액체 비료를 공급하여 비료 성분의 첨가와 관수를 동시에 실시하는 양액토경재배법등이 알려져 있다. 이러한 양액재배법은 시비량을 제어할 수 있어 적당량의 비료 수용액을 어느 작물에도 균등하게 줄 수가 있으므로, 유효한 재배 방법이다.In the nutrient cultivation method, plants are formulated on supports such as gravel, sand, peat, vermiculite, pumice, sawdust, rock wool, and urethane, and the liquid fertilizer is supplied to the plants. Medium culture method, hydroponic method, and nutrient solution soil cultivation method of supplying liquid fertilizer to the root area of crops planted in soil and simultaneously adding and fertilizing fertilizer components are known. This nutrient cultivation method is an effective cultivation method because it is possible to control the fertilization amount and to give an appropriate amount of fertilizer aqueous solution to any crop evenly.
비료 성분의 3대 요소는, 질소, 인산 및 칼륨이지만, 칼슘 등도 식물체의 성장에 빠뜨릴 수 없는 중요한 성분이다. 특히 배지경법, 수경법, 양액토경재배법등과 같은 근권역이 제한된 재배법의 경우에, 칼슘은 중요한 성분이 된다.The three major components of the fertilizer components are nitrogen, phosphoric acid and potassium, but calcium and the like are also important components that are indispensable to plant growth. In particular, in the case of cultivation methods in which the near-area is limited such as culture medium, hydroponics, nutrient solution farming, etc., calcium is an important component.
그렇지만, 인산 및 칼슘이 고농도로 공존하는 경우에는, 인산칼슘의 난수용성 물질이 형성되어 액체 비료 중에 침전물이 생긴다. 이 침전물은 양액재배에 대해 관수 시비 시스템 내의 필터 및 관수 튜브의 관수 구멍의 로딩을 생기게 하고, 혼입기 등의 펌프 기기류에 부하를 줄 뿐만 아니라, 필요한 비료 성분을 공급할 수 없게 되고, 그 결과, 시비 관리를 할 수 없게 되는 등이 사정이 생기는 경우가 있다.However, in the case where phosphoric acid and calcium coexist in high concentrations, a poorly water-soluble substance of calcium phosphate is formed, causing a precipitate in the liquid fertilizer. This deposit causes nutrient cultivation to cause loading of the irrigation holes in the filters and irrigation tubes in the irrigation fertilization system, not only loading the pumping equipment such as incorporators, but also being unable to supply the necessary fertilizer components, resulting in fertilization. The situation may be caused by the inability to manage.
칼슘의 침전이 생기지 않은 복합비료로서 인산 요소와 질산칼슘을 배합한 비료 조성물(특허 문헌 1), 인산 및 인산 1암모늄 또는 인산 1칼륨으로부터 이루어진 복염과, 질산칼슘 또는 인산칼슘을 배합한 비료 조성물(특허 문헌 2)이 제안되고 있다.A fertilizer composition comprising urea phosphate and calcium nitrate (patent document 1), a double salt made of phosphoric acid and ammonium phosphate or monopotassium phosphate, and a fertilizer composition containing calcium nitrate or calcium phosphate Patent document 2) is proposed.
그렇지만, 이러한 비료 조성물은 여러 가지의 결점을 가지고 있다. 예를 들면, 특허 문헌 1 에 기재의 비료 조성물과 같이, 질산칼슘과 인산염을 조합했을 경우에는, 비료 조성물이 대기 중의 수분을 흡수하여 유동성이 손상되는 등, 보관 안정성에 문제가 생긴다. 특히 고온 다습한 하절기에서는, 과도의 수분 흡수에 의해 일부 용해물이 되어, 비료 성분의 칭량이 곤란해지거나 철 등의 타성분과 물불용물을 형성해 버려, 본래의 목적을 달성하지 못하고, 실용적이지 않다. 또, 특허 문헌 2에 기재의 비료 조성물은 특히 인산칼슘을 배합하는 경우에는, 인산 성분 과다가 되어, 타성분과의 균형이 맞지 않고, 과잉의 인산 성분은 땅 속의 철, 아연 등의 식물체에의 흡수를 억제하는 우려가 있으므로 바람직하지 않다.However, these fertilizer compositions have various drawbacks. For example, like the fertilizer composition described in Patent Document 1, when calcium nitrate and phosphate are combined, problems arise in storage stability, such as the fertilizer composition absorbs moisture in the air and impairs fluidity. In summer, especially in high temperature and high humidity, it becomes a partial melt | dissolution by excessive moisture absorption, and it becomes difficult to weigh a fertilizer component, or forms other components, such as iron, and a water insoluble substance, and does not achieve the original objective and is not practical. not. In addition, the fertilizer composition described in Patent Literature 2, in particular, when calcium phosphate is blended, becomes excessive in phosphate components and is not balanced with other components, and excess phosphate components are absorbed into plants such as iron and zinc in the ground. It is not preferable because there is a fear of suppressing.
지금까지, 질산요소는, 질소의 함유율이 높기 때문에, 질소비료로서의 사용 가능성이 검토되고 있었다. 그렇지만, 질산요소는 식물체에 약해(藥害)를 일으키게 하는 등의 이유로써 실용화에 이르지 않고, 비료로서의 유효 이용은 실질적으로 행해지지 않았다.Until now, since urea nitrate has high nitrogen content, the possibility of using it as a nitrogen fertilizer has been examined. However, urea nitrate has not been put into practical use for reasons such as causing weakness to plants, and effective use as a fertilizer has not been practically performed.

In manufacturing a liquid fertilizer composition, it is more preferable to prepare a thick liquid in a 1st process, and to use it as the dilution liquid of a predetermined density | concentration in a 2nd process.
제1 공정의 농후액은 본 발명의 고체 비료 조성물을 3~20배 중량, 바람직하게는 3.5~15배 중량, 더욱 바람직하게는 4~10배 중량의 물에 용해시키는 것으로 조제할 수 있다.The thickening liquid of a 1st process can be prepared by dissolving the solid fertilizer composition of this invention in 3-20 times weight, Preferably it is 3.5-15 times weight, More preferably, 4-10 times weight water.

제2 공정의 희석액은 제1 공정으로 조제한 농후액을, 총사용수량으로서, 사용한 고체 비료 조성물에 대해서 200~5,000배 중량, 바람직하게는 300~3,000 중량, 보다 바람직하게는 500~2,000배 중량이 되도록 물을 첨가하고, 희석하는 것으로 조제할 수 있다. 희석을 수(數)단계로 나누고, 최종적으로 소정 농도가 되도록 할 수 있다.The dilution liquid of the 2nd process is 200-5,000 times weight, Preferably it is 300-3,000 weight, More preferably, 500-2,000 times weight with respect to the solid fertilizer composition which used the thick liquid prepared by the 1st process as total use quantity.

본 발명의 액체 비료 조성물에 의하면, 종래 약해가 생기기 때문에 실용화할 수 없었던 질산요소를 함유하고 있는 것에도 불구하고, 식물체의 근권역, 특히 식물체의 줄기 및 잎에 시용해도 약해가 생기는 우려가 지극히 낮다. 더욱, 시트르산염 용해성으로 분류되는 인산칼슘을 함유하는 것에도 불구하고, 물에 대해서 충분한 용해성을 부여할 수가 있다. 그 때문에, 본 발명의 액체 비료 조성물을 식물체에 시용하는 방법으로서는, 특별히 제한되지 않고, 재배 방법에 따라 적당히 설정할 수가 있다.According to the liquid fertilizer composition of the present invention, even though it contains nitrate urea, which has not been put to practical use because of the weakness of the prior art, there is a very low possibility that the weakness occurs even when applied to the near-zone of the plant, especially the stem and leaves of the plant. . Furthermore, despite containing calcium phosphate classified as citrate solubility, sufficient solubility in water can be imparted. Therefore, it does not restrict | limit especially as a method of applying the liquid fertilizer composition of this invention to a plant, According to a cultivation method, it can set suitably.
재배 방법의 일례로서는, 양액재배에 있어서의 시비 방법을 들 수 있고 수경재배법, 수기경재배(水氣耕栽培)법, 고형 배지경(培地耕)법 등의 순환식 또는 부어서 흐르게 하는 방식의 처리 방법, 고형 배양지 방법 또는 양액토경재배법의 관수 튜브를 이용하는 처리 방법 등을 들 수가 있다.As an example of a cultivation method, the fertilization method in nutrient solution cultivation is mentioned, The process of the circulating-type or pour-flow method of hydroponic cultivation method, hydroponic cultivation method, solid medium diameter method, etc. is carried out. The method, the solid culture paper method, the processing method using a watering tube of a nutrient solution soil culture method, etc. are mentioned.
양액재배법은 식물체의 생장 또는 상황에 맞추어 시비량의 관리를 실시하는 것이고, 그 때문에, 액체 비료 중의 침전물의 형성은 액체 비료 중 성분 농도의 균일화를 해치므로, 설정한 시비 관리의 방해가 된다. 또, 양액재배법에서는, 침전물은 시비 설비의 필터 및 관수 구멍의 폐색을 일으키고, 송액(送液) 시스템에 부하를 걸어 고장의 원인이 될 수 있다. 본 발명의 비료 조성물은 그 뛰어난 수용성이므로, 이들 문제를 회피할 수가 있으므로, 양액재배용 비료에 적합하다.The nutrient cultivation method manages the fertilization amount in accordance with the growth or the situation of the plant. Therefore, the formation of the precipitate in the liquid fertilizer impairs the uniformity of the component concentration in the liquid fertilizer, thus preventing the set fertilization management. In addition, in the nutrient solution cultivation method, the precipitate may cause clogging of the filter and the irrigation hole of the fertilizer, and may cause a failure by applying a load to the liquid feeding system. Since the fertilizer composition of this invention is excellent in water solubility, these problems can be avoided and it is suitable for fertilizer for nutrient solution cultivation.
또, 질산요소는 종자의 발아를 억제하거나 식물체의 엽부에 약해를 현저하게 주지만, 본 발명의 액체 비료 조성물에 의하면, 발아전, 발아 후 등의 식물체의 생육 단계를 불문하고, 특히 경엽에 시용해도 약해를 나타내지 않는다고 하는 뛰어난 효과를 발휘하기 때문에, 살수, 분무 등의 수단에 의해 경엽(莖葉) 처리가 가능하다.In addition, urea nitrate inhibits the germination of seeds or significantly damages the leaves of plants, but according to the liquid fertilizer composition of the present invention, regardless of the growth stage of plants, such as before germination and after germination, especially when applied to foliage Since it shows the outstanding effect that it does not show a weakening, the foliage treatment is possible by means, such as watering and spraying.

코마트나 「夏藥天」(타키이 종묘 주식회사)을 이용하여 재배 시험을 실시했다. 시험 기간은 10월 하순~11월 중순의 24일간으로 했다. 노이바 에르폿트(내경 11.3 cm, 높이 6.5 cm)에 배토(조합 애채(愛菜) 2호, 片倉 치카린 주식회사제) 500 ml 를 충전하고, 포트의 토양 수분량을 50~60% 가 되도록 상기에서 조제한 액체 비료 조성물 1, 비교 비료 1 및 비교 비료 2를 각각 첨가했다. 각 포트에 코마트나 종자 20알을 파종하고, 발아까지의 기간은 필요에 따라서 관수(灌水)했다. 발아 후는 액체 비료 조성물 1, 비교 비료 1 및 비교 비료 2(20~50 ml/일)를 윗쪽보다 엽면(葉面)에 걸리도록 물뿌리개를 사용하여 시용했다.A cultivation test was conducted using Komat or Takii Seedling Co., Ltd. The test period was 24 days from late October to mid-November. 500 ml of clay (combined peach No. 2, manufactured by Chikarin Co., Ltd.) was charged in a Noiba erpot (inner diameter 11.3 cm, height 6.5 cm), and the above-mentioned soil water content of the pot was adjusted to 50 to 60%. Liquid fertilizer composition 1, comparative fertilizer 1 and comparative fertilizer 2 were added, respectively. 20 seeds of coma and seeds were sown in each pot, and the time to germination was irrigated as needed. After germination, the liquid fertilizer composition 1, the comparative fertilizer 1, and the comparative fertilizer 2 (20-50 ml / day) were applied using the watering can so that it might hang on the leaf surface rather than the upper side.
파종 5일 후에 발아수를 세고 발아율(파종수에 대한 발아수의 비율)을 구했다. 또, 파종 14일 후에 약해의 상황을 눈으로 관찰하고, 파종 24일 후에 엽장(葉長) 및 5주 당의 생체중(生體重)을 측정했다. 또 비교 비료 2를 이용한 시험에 대해서는 파종 14일 후에 시험을 종료했다.Five days after sowing, the number of germinations was counted and the germination rate (ratio of germination to seeding number) was obtained. Moreover, 14 days after seeding, the condition of the weakening was visually observed, and 24 days after seeding, the leaf length and the live weight of 5 weeks were measured. Moreover, about the test using the comparative fertilizer 2, the test was complete | finished 14 days after sowing.
시험은 3련제(連制)로 행하고, 각 시험 결과의 평균치를 구하여 표 2에 나타냈다.The test was performed with three refiners, and the average value of each test result was calculated | required and shown in Table 2.
이상, 본 발명의 비료 조성물은 식물체에 대해서 약해를 일으키는 일 없이, 시판 비료와 동등 또는 그 이상의 비료 효과를 발현할 수 있는 것을 알 수 있다.As mentioned above, it turns out that the fertilizer composition of this invention can express the fertilizer effect equivalent to or more than a commercial fertilizer, without causing harm to a plant.
