Abstract

The invention relates to a fertilizer, in particular to a selenium urea formaldehyde roller pelleting compound fertilizer and a production method thereof. After selenium urea formaldehyde is added into the compound fertilizer, agricultural products enriched in selenium cannot only be produced; because a nitrogen element and a selenium element in the selenium urea formaldehyde are chelated, the selenium urea formaldehyde roller pelleting compound fertilizer has a certain release function, and the fertilizer efficacy time is long so as to improve the yield of the crops. On the other hand, the compound fertilizer adopts circulation cooling in the production process and the cooling process, so that fertilizer particles are fully cooled, along with the adhesion of the selenium urea formaldehyde, so that the particle hardness of the compound fertilizer product is high, less water content is introduced into the production without drying, so as to greatly save energy sources.

Description

technical field

[0001] The invention relates to a fertilizer, in particular to a selenourea-formaldehyde roller granulated compound fertilizer and a production method thereof. Background technique

[0002] In the current technical field of producing chemical compound fertilizers, in addition to nitrogen, phosphorus, and potassium, common whole-element fertilizers also contain trace elements such as zinc, copper, boron, and molybdenum, but they do not contain selenium, so they cannot produce selenium-enriched fertilizers. of agricultural products. As we all know, selenium is an indispensable trace element for human life activities. It is an important component of glutathione peroxidase, an antioxidant in red blood cells. Sufficient selenium can promote glutathione peroxidase to effectively convert hydrogen peroxide into water in the human body; selenium is also the dismutation of peroxide Components of enzymes, which can eliminate free radicals and maintain normal levels of...
