Description
Изобретение относитс к получению веществ , подавл ющих нитрификацию аммонийного азота в почве.The invention relates to the production of substances that suppress the nitrification of ammonium nitrogen in the soil.
Цель изобретени - повышение эффективности ингибитора и упрощение процесса .The purpose of the invention is to increase the effectiveness of the inhibitor and simplify the process.
Пример. 100 г органического носител агримуса или гидролизного лингина с влажностью 40% в течение 1-3 мин обрабатывают водным раствором активного производного пиразола из группы: 3(5)-метил-пиразол (МП), 1-карбомоил-3(5}-метилпиразол (КМП), 1-гид- роксиметил-3(5)-метилпиразол (ГМП), и тщательно перемешивают до образовани пастообразной массы. Затем массу сушат до воздушно-сухого состо ни и используют в качестве ингибитора нитрификации. При этом носителем сорбируетс 5-10% активного производного пиразола.Example. 100 g of an organic carrier of agrimus or hydrolysis lingin with a moisture content of 40% is treated with an aqueous solution of an active pyrazole derivative from the group: 3 (5) -methyl-pyrazole (MP), 1-carbomoyl-3 (5} -methylpyrazole ( CMP), 1-hydroxymethyl-3 (5) -methylpyrazole (GMP), and mix thoroughly until a pasty mass is formed. Then the mass is dried to an air-dry state and used as a nitrification inhibitor. % active derivative of pyrazole.
Эффективность ингибитора провер ли в лабораторных услови х на черноземе (Нг -0.89мг-экв на 100 г почвы, гумус (по Тюри- ну)-5,84%. P20s (по Чирикову)-9,31 мг наThe effectiveness of the inhibitor was tested in laboratory conditions on chernozem (Hg -0.89 mg-eq per 100 g of soil, humus (according to Tyurin) -5.84%. P20s (according to Chirikov) -9.31 mg per
100 г почвы рН солевой выт жки-6,6. N общ -0,28%).100 g of soil pH of saline extract is 6.6. N total -0,28%).
Опыты на ингибирующую активность проводили по следующей схеме: вариант 1 почва + фон, вариант 2 почва + фон + удобрение , вариант 3 почва + фон + удобрение + ингибитор.Experiments on the inhibitory activity were carried out according to the following scheme: option 1 soil + background, option 2 soil + background + fertilizer, option 3 soil + background + fertilizer + inhibitor.
Карбамид и ингибитор вносили в почву, Почву помещали в сосуды емкостью 500 мл. Масса воздушно-сухой почвы 500 г на сосуд. Доза N, PaOsn K20 200мг на 1 кг почвы, доза ингибитора 5-10% от количества азота карбамида . Повторность 4-кратна . Компосты помещали в термостат с температурой 28- 30°С. Влажность почвы поддерживали на уровне 60% от полной влагоемкости.Urea and the inhibitor were applied to the soil, the soil was placed in 500 ml vessels. The mass of air-dry soil 500 g per vessel. Dose N, PaOsn K20 200 mg per 1 kg of soil, dose of inhibitor 5-10% of the amount of urea nitrogen. Repetition 4-fold. Composts were placed in a thermostat with a temperature of 28-30 ° C. Soil moisture was maintained at 60% of full capacity.
Через недели после закладки опыта определ ли содержание нитратного азота в почве путем анализа водной выт жки с помощью дисульфофеноловой кислоты.A week after the start of the experiment, the content of nitrate nitrogen in the soil was determined by analyzing the aqueous extract with disulfophenolic acid.
Результаты опытов представлены в таблице .The results of the experiments are presented in the table.

Сравнение эффективности предложенного ингибитора было проведено с извест- ным ингибитором нитрификации, полученным на основе целлюлозосодержа- щего носител , а также с носител ми, не содержащими производных пиразола.A comparison of the effectiveness of the proposed inhibitor was carried out with a known nitrification inhibitor obtained on the basis of a cellulose-containing carrier, as well as with carriers that do not contain pyrazole derivatives.
Из представленных данных видно, что ингибитор нитрификации азотных удобре- тений позвол ет повысить процент ингиби- ровани нитрификации по сравнению с целлюлозосодержащим носителем с 65-70 до 73-87% при значительно более простом способе его получени .From the presented data, it is evident that the nitrification inhibitor of nitrogen fertilizers allows to increase the percentage of inhibition of nitrification as compared with the cellulose-containing carrier from 65-70 to 73-87% with a much simpler method of its preparation.
