Abstract：The planting density has significant efects on the yield of fresh corn.The appropriate planting density can optimize the population structure of fresh corn，facilitating the coordination between asufficient population and strong individual plants，ultimately enhancing yield.This studywasconducted in thecold regionof Taibai Mountain，using the locally planted fresh corn variety Jinguan 218‘as the test material. Five diferent planting densities were set，and intercropping with baby Chinese cabbage was tested.The agricultural traits of fresh corn，along with the yields of both fresh corn and baby Chinesecabbage，were compared，and the comprehensive economic benefits were analyzed.The results indicated that the best intercropping patern for fresh corm and baby Chinese cabbage was a planting density of 3 4OO plants/667 m2 with intercropped baby Chinese cabbage，which obtained the highest economic benefits and total output.This study established the optimal planting density for intercropping fresh corn with baby Chinese cabbage，providing technical guidance for increasing the yield and efficiency offresh corn cultivation and for growing baby Chinese cabbage in the region.
