Abstract

To identify the high yield planting date and pinching pattern, we compared the yields of five new varieties (lines) of tea-applied chrysanthemum, the ‘Suju 10’, ‘Suju 12’, ‘Suju 13’, ‘CH1-44’ and ‘CH5-13’. A field experiment with split-split plot design was carried out. The main plot treatments including three (early, middle and late) planting dates, split-plot treatments including 5 new varieties (lines), and split-split-plot treatments including four different kinds of pinching schemes. The results showed that the yield of ‘CH5-13’ and ‘Suju 13’ was relatively higher among the five varieties (lines), followed by ‘CH1-44’ and ‘Suju10’, and ‘Suju 12’ showed the lowest yield. Among the five varieties (lines), planting date on May 27th and two-time pinching treatments showed the highest values of plant height, crown width, flower number, flower diameter, fresh mass, yield per plant and yield per unit area. Compared with the planting date on May 7th and June 13th, the above indexes increased by 16.0% and 19.0%, 18.0% and 22.8%, 36.7% and 42.2%, 11.1% and 2.3%, 13.0% and 4.0%, 47.8% and 36.6%, 48.5% and 36.7%, respectively. With the pinching time postponed, plant height decreased. Compared with the no pinching treatment, plant height of the two-time pinching treatment decreased by 50.2%, and values of crown width, flowers number, the flower fresh mass, the yield per plant and the yield per unit area were highest, with increases of 17.0%, 29.1%, 5.5%, 34.0% and 34.8%, respectively. The impact performance of three main factors on the growth and yield of the tea-applied chrysanthemum was in order of planting date>varieties>pinching time.

摘要

为确定高产种植日期和打顶方式,我们比较了五个菊花新品种(系)“苏菊10”“苏菊12”“苏菊13”“CH1 - 44”和“CH5 - 13”的产量。进行了裂区裂区设计的田间试验。主区处理包括三个(早、中、晚)种植日期,裂区处理包括5个新品种(系),裂区裂区处理包括四种不同的打顶方案。结果表明,在五个品种(系)中,“CH5 - 13”和“苏菊13”的产量相对较高,其次是“CH1 - 44”和“苏菊10”,“苏菊12”产量最低。在五个品种(系)中,5月27日种植且进行两次打顶处理的株高、冠幅、花数、花径、鲜质量、单株产量和单位面积产量最高。与5月7日和6月13日种植相比,上述指标分别提高了16.0%和19.0%、18.0%和22.8%、36.7%和42.2%、11.1%和2.3%、13.0%和4.0%、47.8%和36.6%、48.5%和36.7%。随着打顶时间推迟,株高降低。与不打顶处理相比,两次打顶处理的株高降低了50.2%,冠幅、花数、花鲜质量、单株产量和单位面积产量最高,分别增加了17.0%、29.1%、5.5%、34.0%和34.8%。三个主要因素对菊花生长和产量的影响表现为种植日期>品种>打顶时间。
