摘要
目的:比较5个茶用和药用菊新品种(系)‘苏菊6号’、‘苏菊9号’、‘CH7-12’、‘CH7-18’、‘CH7-32’的产量水平并筛选出适宜高产的定植期和摘心方案。方法:试验采用三因素裂区试验设计,三个主区为早、中、晚3个定植期,分别是5月7日、5月27日、6月13日,裂区为5个茶药菊新品种(系),裂裂区为4种摘心方案,分别为不摘心,早一次摘心,晚一次摘心,二次摘心,于盛花期测量株高、冠幅、单株花数、花径、单花鲜重和单株产量,比较不同栽培措施的差异。结果:‘苏菊9号’、‘CH7-12’和‘CH7-18’为高产品种(系),产量高于其余2个品种(系)。5月27日定植、生长期二次摘心处理下5个新品种(系)的生长、开花指标及单株产量显著优于其它处理。随着摘心时间的推迟,株高显著降低,二次摘心后冠幅、单株花数、单株产量和估算产量最高,较不摘心依次提高27.6%、50.4%、41.0%和50.0%,但株高较不摘心降低30.7%。结论:品种(系)、定植期、摘心方案三个因素对茶药菊生长性状和产量性状影响作用的大小依次为:定植期>品种>摘心。
Objective:To compare the yield levels of five new varieties of Chrysanthemum morifolium‘Suju 6’,‘Suju 9’,‘CH7-12’,‘CH7-18’,‘CH7-32’for tea and medicine,to select the suitable planting period and pinching schemes for high yield.Methods:A split-split plot designed field experiment was established.The three main zones were three planting dates:early,middle and late,which were May 7 th,May 27 th,June 13 th.The split-plot treatment was five new varieties of Chrysanthemum morifolium(lines)for tea and medicine and the split-split-plot treatment was four kinds of pinching schemes,which were no pinching,earlier one-time pinching,late one-time pinching and two-times pinching,respectively.Plant height,crown width,number of flowers per plant,diameter of flowers,fresh weight of single flower and yield per plant were measured at flowering stage to compare the differences of different cultivation measures.Results:The‘Suju 9’,‘CH7-12’and‘CH7-18’were high-yield variety(lines)and higher than that of the other two varieties(lines).Planting on May 27 th with two-times pinching,the growth,flowing index and yield of a single plant of the five new varieties(lines)were significantly better than those of other treatments.With the delay of the pinching,the plant height decreased significantly.The crown width,flower number per plant,yield per plant and estimated yield were the highest after two-times pinching,which increased by 27.6%,50.4%,41.0%and 50.0%,respectively compared with no pinching,but the plant height decreased by 30.7%compared with no pinching.Conclusion:The effects of varieties(lines),planting date and pinching scheme on the growth and yield traits of Chrysanthemum morifolium for tea and medicine is planting date>variety>pinching.
