Abstract
Description
Изобретение относится к ингибиторам нитрификации азотных удобрений в почве и может быть использовано в сельском хозяйстве.The invention relates to inhibitors of nitrification of nitrogen fertilizers in the soil and can be used in agriculture.
Ингибиторы нитрификации ограничивают деятельность почвенных бактерий, превращающих аммонийные и амидные формы азота удобрений в нитратные, которые быстрее удаляются из почвы благодаря вымыванию и разложению с образованием газообразных продуктов.Nitrification inhibitors limit the activity of soil bacteria, which convert the ammonia and amide forms of nitrogen fertilizers into nitrate, which are more quickly removed from the soil due to leaching and decomposition with the formation of gaseous products.
Известно применение различных гетероциклических соединений в качестве ингибиторов нитрификации азотных удобрений в почве (GB 1592516, A01N 43/56, 1981; SU 1113379, C07D 231/12, C05G 3/08, 1984; SU 1488291, C05G 3/08, 1989; SU 1673579, C05G 3/08, 1991; RU 2083538, C05G 3/08, 1997).The use of various heterocyclic compounds as inhibitors of nitrification of nitrogen fertilizers in soil is known (GB 1592516, A01N 43/56, 1981; SU 1113379, C07D 231/12, C05G 3/08, 1984; SU 1488291, C05G 3/08, 1989; SU 1673579, C05G 3/08, 1991; RU 2083538, C05G 3/08, 1997).
Наиболее близким к изобретению является известное применение 4-амино-1,2,4-триазола в качестве ингибитора нитрификации азотных удобрений в почве (GB 1217547, A01N 7/00, 1970). Однако синтез этого соединения достаточно сложен и связан с взрывоопасностью получаемого продукта, связанной, по-видимому, с присоединением аминогруппы к атому азота триазольного цикла (http://chemister.ru/Database/properties.php?dbid=1&id=929; RU 2036912, C07D 249/08, 1995).Closest to the invention is the known use of 4-amino-1,2,4-triazole as an inhibitor of nitrification of nitrogen fertilizers in soil (GB 1217547, A01N 7/00, 1970). However, the synthesis of this compound is quite complicated and is associated with the explosiveness of the resulting product, apparently associated with the addition of an amino group to the nitrogen atom of the triazole ring (http://chemister.ru/Database/properties.php?dbid=1&id=929; RU 2036912 C07D 249/08, 1995).
Техническая задача, на решение которой направлено изобретение, состоит в увеличении доступности ингибитора нитрификации.The technical problem to which the invention is directed is to increase the availability of a nitrification inhibitor.
Для решения этой задачи предложено применение 3.5-диамино-1,2,4-триазола и его солей с неорганическими кислотами в качестве ингибиторов нитрификации азотных удобрений.To solve this problem, the use of 3.5-diamino-1,2,4-triazole and its salts with inorganic acids as inhibitors of nitrification of nitrogen fertilizers is proposed.
Неожиданно оказалось, что 3.5-диамино-1,2,4-триазол и его соли обладают более высокой способностью к ингибированию нитрификации азотных удобрений, чем 4-амино-1,2,4-триазол, несмотря на принципиальные различия в структуре - аминогруппы 3.5-диамино-1,2,4-триазола присоединены не к атомам азота, а к атомам углерода триазольного цикла.It turned out unexpectedly that 3.5-diamino-1,2,4-triazole and its salts have a higher ability to inhibit the nitrification of nitrogen fertilizers than 4-amino-1,2,4-triazole, despite the fundamental differences in the structure of the amino group 3.5 -diamino-1,2,4-triazole attached not to nitrogen atoms, but to the carbon atoms of the triazole ring.
3.5-диамино-1,2,4-триазол известен и используется в качестве исходного вещества для синтеза ряда высокоэнергетических и биологически активных соединений, полимеров, красителей и фотоматериалов; при этом его синтез осуществляется с помощью достаточно простого способа, не связанного с какими-либо производственными опасностями (В.А, Таранушич. Прямой синтез амино- и нитропроизводных 1,2,4-триазола из гидразина и дициандиамида // В сб.: Химия, химические технологии и химическое машиностроение: Тез. докл. отчетной конференции "Совершенствование организации научных исследований по тематическим планам высших учебных заведений министерства образования России" за 1999-2001 годы/ РХТУ им.

A, Taranushich. Direct synthesis of amino and nitro derivatives of 1,2,4-triazole from hydrazine and dicyandiamide // Sat: Chemistry , Chemical Technologies and Chemical Engineering: Abstract of the report conference "Improving the organization of scientific research on the thematic plans of higher education institutions of the Ministry of Education of Russia" for 1999-2001 / RCTU named after DI Mendeleev, Moscow: 2002, h. 1, p. 32-37; http://ch.em21.info/page/0070682380780680630931 55031079026035073058032255 /).
Сущность изобретения иллюстрируется приведенными ниже примерами.The invention is illustrated by the following examples.
Пример 1. В шесть сосудов емкостью по 500 мл помещают по 500 г воздушно-сухой почвы - в три сосуда серозем и в три сосуда чернозем. В два сосуда с сероземом и в два сосуда с черноземом добавляют по 215 мг карбамида (содержание амидного азота 200 мг/кг почвы). В один сосуд с сероземом и один сосуд с черноземом, куда был добавлен карбамид, добавляют по 1 мг 3,5-диамино-1,2,4-триазола (1% по отношению к азоту карбамида). Затем увлажняют почву до 60% от полной влагоемкости и выдерживают сосуды в термостате при 28-30°С в течение 30 дней, после чего определяют во всех сосудах содержание нитратного и нитритного азота по ГОСТ 26951-86.Example 1. In six vessels with a capacity of 500 ml are placed 500 g of air-dried soil - in three vessels of sierozem and in three vessels of chernozem. In two vessels with serozem and in two vessels with chernozem, 215 mg of carbamide (amide nitrogen content 200 mg / kg of soil) is added. 1 mg of 3,5-diamino-1,2,4-triazole (1% with respect to urea nitrogen) is added to one vessel with serozem and one vessel with chernozem where urea was added. Then the soil is moistened up to 60% of the total moisture capacity and the vessels are kept in the thermostat at 28-30 ° С for 30 days, after which the content of nitrate and nitrite nitrogen is determined in all vessels according to GOST 26951-86.
Степень ингибирования нитрификации /, %, вычисляют по формулеThe degree of inhibition of nitrification /,%, calculated by the formula
где а - содержание нитратов и нитритов после испытания в образце почвы, куда внесен карбамид без ингибитора;where a is the content of nitrates and nitrites after testing in a soil sample, where urea was added without an inhibitor;
b - содержание нитратов и нитритов после испытания в образце почвы, куда внесен карбамид с ингибитором; b - the content of nitrates and nitrites after testing in a soil sample, where urea with an inhibitor is introduced;
с - содержание нитратов и нитритов в контрольном образце почвы, куда карбамид не вносили. c is the content of nitrates and nitrites in the control soil sample, where urea was not added.
Результаты испытаний по этому и последующим примерам приведены ниже в таблице.The test results for this and subsequent examples are shown in the table below.
Пример 2. Испытания проводят аналогично примеру 1 с тем отличием, что вместо 3,5-диамино-1,2,4-триазола в сосуды с почвой вводят его гидрохлорид в количестве 1 мг (в расчете на 3,5-диамино-1,2,4-триазол).Example 2. Tests are carried out analogously to example 1 with the difference that instead of 3,5-diamino-1,2,4-triazole, its hydrochloride is introduced into vessels with soil in an amount of 1 mg (based on 3,5-diamino-1, 2,4-triazole).
Пример 3. Испытания проводят аналогично примеру 1 с тем отличием, что вместо 3,5-диамино-1,2,4-триазола в сосуды с почвой вводят его сульфат в количестве 1 мг (в расчете на 3,5-диамино-1,2,4-триазол).Example 3. Tests are carried out analogously to example 1 with the difference that instead of 3,5-diamino-1,2,4-triazole, its sulfate is introduced into vessels with soil in an amount of 1 mg (calculated as 3,5-diamino-1, 2,4-triazole).
Пример 4. Испытания проводят аналогично примеру 1 с тем отличием, что вместо 3,5-диамино-1,2,4-триазола в сосуды с почвой вводят его фосфат в количестве 1 мг (в расчете на 3,5-диамино-1,2,4-триазол).Example 4. Tests are carried out analogously to example 1 with the difference that instead of 3,5-diamino-1,2,4-triazole, its phosphate is introduced into vessels with soil in an amount of 1 mg (based on 3,5-diamino-1, 2,4-triazole).
Пример 5 (сравнительный). Испытания проводят аналогично примеру 1 с тем отличием, что вместо 3,5-диамино-1,2,4-триазола в сосуды с почвой вводят 4-амино-1,2,4-триазол в количестве 1 мг.Example 5 (comparative). The tests are carried out analogously to example 1 with the difference that instead of 3,5-diamino-1,2,4-triazole, 1-mg-1,2,4-triazole is introduced into the soil vessels.
Как видно из таблицы, при использовании 3.5-диамино-1,2,4-триазола и его солей с соляной, серной и фосфорной кислотами степень ингибирования нитрификации возрастает на черноземе на 5-15% и на сероземе на 3-10% по сравнению с использованием 4-амино-1,2,4-триазола. Это позволяет повысить степень использования азотных удобрений в почве и сократить их расход.As can be seen from the table, when using 3.5-diamino-1,2,4-triazole and its salts with hydrochloric, sulfuric and phosphoric acids, the degree of inhibition of nitrification increases on chernozem by 5-15% and on serozem by 3-10% compared with using 4-amino-1,2,4-triazole. This allows you to increase the degree of use of nitrogen fertilizers in the soil and reduce their consumption.
