FERTILIZER FOR CORN CONTAINING GLYCINEBETAINE AND POLY ASPARTIC ACID TO REDUCE THE USE OF FERTILIZER USAGE

摘要

PURPOSE: A corn fertilizer containing polyaspartic acid and glycine betaine is provided to maintain the growth and the quantity of crops using the nutrient absorption promoting effect of glycine betaine and the ion absorbing capability of the polyaspartic acid. CONSTITUTION: A corn fertilizer includes 0.75-1 parts by weight of complex fertilizer, 0.005 parts by weight of polyaspartic acid, and 0.0015 parts by weight of glycine betaine. The complex fertilizer includes nitrogen, phosphorus, and potassium. The content of the nitrogen in the complex fertilizer is 12 weight%. The content of the phosphorus in the complex fertilizer is 5 weight%. The content of the potassium in the complex fertilizer is 9 weight%.
