Long-acting fertilizer containing mixing fodder and its production method

Abstract

The re-mixed feed is produced through adding long-acting ammonium bicarbonate in 6-12 wt% or long-acting urea in 3-6 wt% into air dried stalk or mixed feed, and the long acting chemical fertilizer is chemical fertilizer with dicyandiamide added in 0..5-1 wt%. In addition, the nutritious re-mixed feed of slowly releasing urea may have proper amount of coarse protein, starch, zeolite powder and mineral matter, such as salt, phosphate, potassium, sulfur, iron, manganese, etc. added.

Description

technical field [0001] The invention provides a compound feed containing long-acting chemical fertilizers and a production method thereof, in particular a compound feed containing long-acting ammonium carbonate or urea and a production method thereof. Background technique [0002] The cellulose part contained in plant straw can be digested and utilized by ruminants such as cattle and sheep, while the lignin part cannot be digested and utilized basically. The main function of ammonification is to use ammonia to react with straw, destroy the ester bond connecting lignin and polysaccharide, and make it easy for digestive enzymes to contact with it, thereby increasing the enzymatic hydrolysis speed of straw and promoting the digestion of straw. Rate. The non-protein nitrogen in ammoniated straw can meet the metabolic needs of microorganisms in the rumen and promote the synthesis of microbial proteins. After these protein-containing microorganisms enter the small intestine, und...

Problems solved by technology

Therefore, the long-term test results show that the amount of urea feed used should not exceed 2% of the total dry matter in the daily ration, and even if the amount of urea fed is 2%, the decomposition and utilization rate of ammonia is only 50%-60%. About % can not be used by microorganisms
