摘　　要：在裂区设计下,分析影响欧洲菊苣（Cichorium intybus cv.Europ）产量的7个因素,结果表明：播种季节对株高、产量有显著性影响;播种方式对株高、茎粗、密度、盖度、产量5个指标均有显著影响。进一步通过因子分析得出欧洲菊苣产量最佳组合为撒播、密度在50-59株·m-2、盖度为94%-100%。Factors which affected the production of Cichorium intybus under the split plot design were studied. The results showed that planting season had significant effect on plant height and yield. While, seeding method had significant impact on plant height, stem diameter, density, coverage and yield. Further by factor analysis found that the best combination of production for Cichorium intybus was broadcast sowing, a seedling density of 50-59 strain · m-2, and a coverage of 94%-100%.
