PURPOSE: A manufacturing method of dried seaweed culturing agent and dried seaweed culturing agent are provided to improve quality of dried seaweed and to increase quantity thereof by using nutrients which include phosphorus, magnesium, zinc, and nitrogen. CONSTITUTION: A dried seaweed culturing agent comprises 80-90 weight% of amino acid liquid fertilizer, 8-19 weight% of magnesium sulfate, and 0.1-2 weight% of effective Microorganisms(EM). A manufacturing method of the amino acid liquid fertilizer comprises the following steps: mixing 80-90 weight% of water, 3-10 weight% of raw milk, 1-5 weight% of microorganism, and 1-5weight% of molasses； and aging the mixture at 25-35 deg. Celsius for 14-20 days. The microorganism is more than one or two kinds selected from Bacillus licheniformis, Bacillus pumilus, or Bacillus subtilis. The molasses has component formation of 23.50% of moisture, 4.21% of crude protein, 4.21, 0.05% of crude fat, 0.06% of crude fiber, 6.53% of coarse ash, and 65.65% of carbohydrate. A manufacturing method of the dried seaweed culturing agent comprises the following steps: mixing 80-90 weight% of amino acid liquid compost, 8-19 weight% of magnesium sulfate, and 0.1-2 weight% of effective microorganism； and aging the mixture at humidity of 40-45% and temperature at 40-50 deg. Celsius for 5-7 days.본 발명은 김 양식제에 관한 것으로서, 더욱 상세하게는 아미노산 액체비료와, 액상 황산마그네슘와, 유용미생물의 혼합으로 조성된 김 양식제에 관한 것이다.
