【摘要】 为使非洲菊鲜切花延长瓶插寿命和提高保鲜质量,以非洲菊品种‘特拉维撒’为试验对象,以0、0.2、0.4、0.6mL洗洁精和0、15、30、45m L的鲜橙多果汁交叉组合,再分别加入1%Na Cl与3%白砂糖混合溶液组成的100 mL保鲜液中,研究了16种保鲜剂对非洲菊鲜切花的花径变化、瓶插寿命和瓶插观赏值的影响。结果表明,果汁含量为300 mL/L的处理可以延缓瓶插切花开放的状态,保鲜效果较好;在果汁含量相同的条件下,洗洁精含量为0.4 mL/L的处理比含量为0、2和6 mL/L的处理对切花的保鲜效果更佳。处理为300 mL/L果汁+4 mL/L洗洁精+1%盐溶液+3%糖溶液最有利于改善鲜切花的保鲜效果,为较为理想的家庭自制保鲜剂。更多还原

【Abstract】 In order to extend the vase life and improve the preservation quality of gerbera cut flowers, 16 kinds of preservatives’ effects on the flower diameter change of gerbera fresh cut flowers, vase life and bottle insertion viewing values were studied with‘Travisa’ gerbera variety as an example by adding 0,0.2,0.4,0.6 mL detergent in 100 mL preservative solution and 0,15,30,45 mL of fresh orange juice cross combination, and adding 1% NaCl and 3% white sugar mixed solution. The results showed that the treatment with the juice content of 300 ml/L could delay the opening of the cut flower, and the fresh-keeping effect was better.Under the condition of the same juice content, the fresh-keeping effect of edetergent of 0.4 mL/L was better than that of 0,2 and 6 mL/L. Treatment with 300 mL/L of juice+4 mL/L detergent+1% salt solution+3% sugar solution was the most beneficial to improve the fresh-keeping effect of fresh cut flowers, and was an ideal home-made preservative.更多还原
