摘要：

为研究栽培措施对贡菊生长与产量的影响，采用早、中、晚 3个定植期（分别是5月1日、5月20日、6月10日），设不摘心、1次摘心、2次摘心3种摘心方案，在盛花期调查统计株高、冠幅、单株花数、花径、单花鲜重和单株产量，比较不同栽培措施对贡菊产量的影响。结果表明，5月20日定植、生长期2次摘心处理下贡菊的生长、开花指标及单株产量显著优于其他处理；5月20日定植2次摘心后冠幅、单株花数、单株产量最高，较不摘心依次提高26.39%、8.76%和14.86%，但株高和单花鲜重较不摘心分别降低16.97%和8.76%。适合贡菊高产栽培的措施为定植期为5月20日、摘心次数为2次，该栽培措施能够提高贡菊的产量。

Abstract:

To study the influence of cultivation measures on the growth and yield of Chrysanthemum morifolium ‘Gongju’, three planting dates (respectively May 1, May 20 and June 10) were adopted by setting no topping, one time topping and two times topping as the treatments. The plant height, crown width, number of flowers per plant, flower diameter, fresh weight of single flower and yield per plant of C. morifolium ‘Gongju’ were counted during the flowering period, and the effects of different cultivation measures on the yield of C. morifolium ‘Gongju’ were compared. The results showed that: under the treatment of planting on May 20 and two times topping, the growth, flowering indexes and single plant yield of C. morifolium ‘Gongju’ were significantly better than those of other treatments; the crown width, the number of flowers per plant and the yield per plant of planting on May 20 and two times topping were the highest, increased by 26.39%, 8.76% and 14.86%, respectively, compared with those of no topping, but the plant height and the fresh weight of single flower decreased by 16.97% and 8.76% respectively. In summary, planting on May 20 and two times topping is the suitable cultivation measure which can improve the yield of C. morifolium ‘Gongju’.
