| 种植密度对鲜食玉米产量具有显著性影响，适宜的种植密度可优化鲜食玉米群体结构，实现足群体和壮个体协同，进而提高产量。试验在太白高山冷凉地区，以当地主栽鲜食玉米品种金冠218为试验材料，设置5个种植密度，并间作娃娃菜，比较分析不同密度及间作栽培下鲜食玉米农艺性状、鲜食玉米与娃娃菜的产量和综合经济效益。结果表明，鲜食玉米种植密度为3 400株/667 m2下间作娃娃菜，经济效益及总产值最高，是最适宜太白县的鲜食玉米/娃娃菜间作模式。本研究明确了鲜食玉米间作娃娃菜的合理种植密度，为该地区鲜食玉米增产增效栽培和娃娃菜种植提供了技术依据。 |

| The planting density has significant effects on the yield of fresh corn. The appropriate planting density can optimize the population structure of fresh corn, facilitating the coordination between a sufficient population and strong individual plants, ultimately enhancing yield. This study was conducted in the cold region of Taibai Mountain, using the locally planted fresh corn variety 'Jinguan 218' as the test material. Five different 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 Chinese cabbage, were compared, and the comprehensive economic benefits were analyzed. The results indicated that the best intercropping pattern for fresh corn and baby Chinese cabbage was a planting density of 3 400 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 of fresh corn cultivation and for growing baby Chinese cabbage in the region. |
