The invention relates to a method for planting Chinese trumpet creepers in paddy fields. Forty-centimeter rice stubble is reserved, 2.5kg Chinese trumpet creepers are sowed per mu, 3 kg ammonium sulfate is used per mu, 20 kg calcium superphosphate is adopted per mu, at least 5 kg of potassium chloride is used per mu, 0.5 kg zinc sulfate is used per mu, and 0.02 kg ammonium molybdate is adopted per mu; shorter rice stubble can be reserved for dwarf rice varieties, after rice is harvested, the Chinese trumpet creepers are evenly scattered in the fields, and meanwhile phosphate fertilizer and potassic fertilizer are broadcasted to promote growth of the Chinese trumpet creepers. The method has the technical advantages that crawling growth of the Chinese trumpet creepers is balanced to achieve spatial development, and growth of the Chinese trumpet creepers is facilitated; after the Chinese trumpet creepers are turned over and pressed, C and N are balanced, and fertilizer needed in the growth period of rice is balanced; the stubble height of rice is increased, the yield of fresh grass of the Chinese trumpet creepers can be increased, soil is fertilized, rice yields are improved, and economic benefits of the Chinese trumpet creepers and the rice are increased.
