The invention discloses a chemical regulation agent for corn growth. Each 1 kg of chemical regulation agent consists of the following materials: 18-22 mg of gibberellins, 10-20 g of potassium dihydrogen carbonate, 10-20 g of urea, 5-15 g of amino acid leaf fertilizer, 0.1-0.5 mg of brassinolide and the balance of water. According to the invention, the male and female interval of the tasseling stage and the silking stage of corn seedlings is shortened to improve the corn seedling pollination and the yield; besides, the chemical regulation agent facilitates the improvement on the grain filling rate, accelerates the fullness of grains, and is suitable for industrial production.
