The invention belongs to the field of crop production and discloses a seasonal drought relieving and high yield ensuring compound agent for double cropping rice. The compound agent includes an early-season rice special type and a later-season rice special type. The early-season rice special type includes, by weight, 50% of hydroxyethylcellulose, 20% of amino acid raw powder, 15% of monopotassium phosphate, 10% of potassium fulvate, 2.5% of zinc sulfate, 2% of prohexadione calcium, 0.2% of compound sodium nitrophenolate, and 0.05% of abscisic acid; and the later-season rice special type includes, by weight, 30% of hydroxyethylcellulose, 30% of amino acid raw powder, 20% of potassium fulvate, 10% of monopotassium phosphate, 5% of Kang polyphenol, 4.8% of zinc sulfate, and 0.2% of sodium alpha-naphthylacetate. In the formula, comprehensive drought resistant capability of rice is improved through several ways. The compound agent is quick in effects, has long lasting time and has good effects. 本发明属于农作物生产领域，公开了双季稻季
