The invention discloses a method for reducing the early bolting of Chinese angelica. The method includes selecting black soil and heilu soil with excellent conditions to perform sowing, the period ofcrop rotation being more than 3 years, performing shallow ploughing for one time before sowing, applying well-rotted farmyard manure, urea, diammonium phosphate and potassium sulfate before the soil is turned up, and killing pests; then transplanting seedlings, and selecting soybean seeds to perform dibbling; performing sterilization on the seedlings before transplanting, and performing air-dryingwhile performing soaking; performing transplanting in mid-to-late March, performing covering with wide films to perform dibbling, and planting one row of soybeans and three rows of Chinese angelica after mulching; during the transplanting of the Chinese angelica, respectively planting one seedling on the two sides of each hole, the distances of the terminal bud on the heads of the seedlings of the Chinese angelica from the mulching films being 2-3 cm, performing compacting with fine soil, and tightly sealing broken gaps; and during the dibbling of the soybeans, putting 2 soybean seeds in eachhole, performing compacting with the fine soil, and tightly sealing the broken gaps. The bolting rates after the intercropping of the Chinese angelica and the soybeans are lower than that of the monoculture of the Chinese angelica; the influence of different intercropping ratios on the bolting rates is different; when the Chinese angelica is intercropped with the soybeans in a ratio of 3:1, the bolting rate of the Chinese angelica is the lowest, which is only 26.06%; and the annual growth rate of the Chinese angelica can reach up to 66%.
