Abstract: The present disclosure belongs to the technical field of value-added urea preparation, and specifically relates to a two-component foam inhibitor and a preparation method thereof, and a method for reducing foaming in production of urea humate. In the present disclosure, a foam control agent in the two-component foam inhibitor lowers a pH value of a humate solution to reduce the production of ammonia in a urea melt, and can avoid condensation of the humate solution caused by lowering the pH value and a difficulty in adding the humate solution to the urea melt. A suspension adsorbent in the two-component foam inhibitor can adsorb free ammonia in the urea melt and ammonia generated after adding the humate solution. In summary, the two-component foam inhibitor can effectively reduce a foaming reaction during production of the urea humate, avoid powdering of urea humate particles, and improve a production efficiency.

Abstract: This invention relates to the field of genetic molecular breeding, specifically to a pig 50K liquid-phase chip based on multiple single nucleotide-polymorphism and its application. The probe design of the chip in this invention takes into account the distribution of captured SNP loci across the genome, the polymorphism of the loci, the quality of mSNP markers, and other issues, effectively avoiding problems such as uneven marker density and poor polymorphism.
