摘　　要：在成都地区进行了彩色大白菜最适播期的研究。结果表明,随着播期的推迟,彩色大白菜的生育期延长,开展度减小,株高呈先增后减的趋势,软腐病的发生率呈升→降→升的趋势。在不同的播期下,产量及经济效益均显著高于当地品种黄心白。成都地区彩色大白菜适播种期为8月下旬至9月上旬,最佳播种时间为8月底。Two varieties of color Chinese cabbage were sown at different dates to study the optimum sowing date in Chengdu region. The results showed that its growth period was prolonged, its canopy size was decreased, its plant height presented the trend of first increase and then decrease and the occurrence rate of soft rot disease presented a rise-fall-rise trend when sowing tlme was delayed. The yield and economic benefit of color Chinese cabbage varieties under different sowing dates were significantly higher than Huangxinbai （a local cabbage variety）. The suitable sowing dates for color Chinese cabbage was from the last ten-day period of August to the first ten-day period of September and the optimum sowing date was on 30th, August in Chengdu region.
