Description

На некоторых почвах, как, например, на подзолистых, красноземах, суглинках и других больший прирост урожа  получаетс  при внесении фосфорного удобрени , РЮз которого находитс  в цитратно-растворимой усво емой форме.On some soils, such as, for example, podzolic, red soils, loams, and others, a greater yield increase is obtained when applying phosphorus fertilizer, which is in a citrate-soluble assimilable form.

Ранее выпускалс  в качестве удобрени  преципитат, в котором вс  фосфорпа  кислота находитс  в цитратпо-растворимой форме, однако ввиду сложпости пропессов его получени  и дороговизны ом в насто щее врем  не производитс .Earlier, precipitate was produced as a fertilizer, in which all phosphorus acid is in citrate-soluble form, however, due to the complexity of the process, its production and high cost are not currently being carried out.

Предлагаетс  простой способ получени  удобрени , РЮ.; которого находитс  в цитратно-растворимой форме. Способ заключаетс  в следующем . Обычный камерный суперфосфат подвергают нагреву в течение 0,5-1,5 час. нри-температуре около 200°, при этом вс  фосфорна  кислота переходит в цитратно-растворимую форму. Полученный продукт обладает хорошими физическими свойствами и повышенным содержанием питательных вешеств, не слеживаетс  и доступен растени м.A simple method for producing fertilizer, PJ; which is in citrate-soluble form. The method is as follows. Conventional chamber superphosphate is heated for 0.5-1.5 hours. at a temperature of about 200 °, with all the phosphoric acid becomes a citrate-soluble form. The resulting product has good physical properties and a high content of nutrient substances, is not caking and is available to plants.

Дл  определени  цитратной растворимости Р2О5 в удобрении примен ют известный дл  высушенных суперфосфатов метод анализа с предварительной гидратацией, перед осаждением, содержащейс  в выт жке РЮз минеральной, например сол ной, кислотой.To determine the citrate solubility of P2O5 in fertilizer, the well-known pre-hydration method used for dried superphosphates is used, which is contained in a mineral, for example hydrochloric acid, before precipitation.

1. Способ получени  фосфорного удобрени , содержащего РЮз в цитратно-растворимой форме, отличающийс  тем, что, с целью улучшени  физических свойств удобрени  и повышени  в нем содержани  питательных веществ, камерный суперфосфат подвергают нагреву при температуре около 200° в течение 0,5-1,5 час.1. A method of producing phosphate fertilizer containing RLH in citrate-soluble form, characterized in that, in order to improve the physical properties of the fertilizer and increase its nutrient content, chamber superphosphate is heated at about 200 ° for 0.5-1. , 5 hours № 116222- 2 -No. 116222-2 - 2. Способ поп 1,отличающийс  тем, что, с целью определени  цитратной растворимости Р2О5 в удобрении, примен ют известный дл  высушенных суперфосфатов метод анализа с предварительной гидратацией , перед осадедением, содержащейс  в выт жке РЮз минеральной, например сол ной, кислотой.2. A method of pop 1, characterized in that, in order to determine the citrate solubility of P2O5 in fertilizer, the method of analysis with preliminary hydration, known for dried superphosphates, is used, before precipitation, contained in a mineral mineral, for example hydrochloric acid.
