Description
шивать 7-10 мин. Готовый продукт содержит 69% мочевины и 11% уротропина .sew 7-10 minutes The finished product contains 69% urea and 11% hexamine.
Этим способом приготовл ют удобрение , содержащее 0,44 г мочевины и различные количества уротропина. Полученную смесь внос т в 1 кг карбонатной почвы и через 3; 10; 15; 30; 45 и 60 сут отбирают пробу и определ ют в ней содержание нитратного азота. Полученные результаты представлены в таблицеA fertilizer containing 0.44 g of urea and varying amounts of hexamine is prepared using this method. The resulting mixture is added to 1 kg of carbonate soil and after 3; ten; 15; thirty; 45 and 60 days take a sample and determine the content of nitrate nitrogen in it. The results are presented in the table.
что при содержании в предложенном удобрении 18-58% уротропина наблюдаетс уменьшение скорости нитрификации азота мочевины в почве по срав нению с известным удобрением. При ко центрации .уротропина менее 18% нитрификаци протекает интенсивно, увеличение концентрации уротропина выше 58% не целесообразно,, так как скорость нитрификации практически не из мен етс . Помимо указанного преимущества, заключающегос в меньшей скорости нитрификации при использовании предлагаемого удобрени , оно не токсично дл растений, животных и человека и благодар содержанию азота (около 40%) позвол ет сократить норму расхода -других азотных удобрений. Медленнодействующее азотное удобрение , содержащее мочевину и ингибитор нитрификации азота, о т л и чающеес тем, что, с целью уменьшени скорости нитрификации азота мочевины в почве, оно содержит в качестве ингибитора нитрификации уротропин при следующем соотношении компонентов, вес.%: Мочевина Уротропин Источники информации, прин тые во внимание при экспертизе 1.Nitrogen, 1972, № 80, с. 35. 2.За вка ФРГ № 2531962, кл. 16 е 3/08, 1977.that when the proposed fertilizer contains 18-58% urotropin, a decrease in the nitrification rate of urea nitrogen in the soil is observed as compared with the known fertilizer. When the concentration of .urotropine is less than 18%, nitrification proceeds intensively, an increase in the concentration of urotropine above 58% is not advisable, since the rate of nitrification remains almost unchanged. In addition to this advantage, which is a lower nitrification rate when using the proposed fertilizer, it is non-toxic to plants, animals and humans and, due to its nitrogen content (about 40%), reduces the consumption rate of other nitrogenous fertilizers. Slow-acting nitrogenous fertilizer containing urea and nitrogen nitrification inhibitor, which means that, in order to reduce the rate of nitrification of urea nitrogen in the soil, it contains urotropin as a nitrification inhibitor in the following ratio of components, wt.%: Urea Urotropin Information sources , taken into account in the examination 1.Nitrogen, 1972, No. 80, p. 35. 2. For the Germany of Germany No. 2531962, cl. 16 F 3/08, 1977.
