Abstract
The present invention provides a boron-containing synergistic urea and preparation method and application thereof, the boron-containing synergistic urea is a product obtained by mixing, dehydrating and pelletizing a mixed aqueous solution of polyaspartic acid chelated potassium (also referred to as 'polypeptide chelated potassium') and a borate amine salt together with molten urea, wherein the above three components are 0.04-0.12%, 0.08-0.24% and 99.64-99.88% by weight, respectively. The boron-containing synergistic urea provided by the present invention is obtained by effectively compositing polypeptide acid chelated potassium, borate amine salt and urea, which also can guarantee the application amount of effective boron, and meanwhile can help avoid excessive high local concentrations of boron, and achieve the purposes of prompting effective absorption of the plant to boron and of improving urea utilization rate.
