摘要/Abstract

摘要： 试验结果表明, 非洲菊7 个切花品种冬季无土栽培根际加温可促进其产花。根温为20 ℃时显著提高了切花的产量与质量, 单株产量、花茎长、茎粗、花重较对照分别提高了71. 34 %、19. 14 %、8. 5 %、23. 72 % , 但对花径的增大作用不显著。根温为15 ℃时可显著提
高切花产量, 较对照切花增产33. 21 %; 对花茎长、茎粗生长也有促进作用, 但对花径、花重
无显著影响。根际加温对不同品种增加产量与提高质量效果不同, 根际加温至20 ℃时, 品种
‘日’、‘签证’与‘莫尔’产量较高, 质量优良: 冬季84 d 产量可达9. 90、9. 56 与9. 30 支/株, 花径为10. 21、9. 92 与10. 05 cm , 花茎长为55. 10、53. 61 与54. 82 cm , 茎粗为0. 65、0. 63与0. 61 cm , 花重为21. 52、22. 68 与22. 50 g。

Abstract: The effects of rhizsphere heating on flower yields and quality of 7 species of Gerbera , which are grown under soilless condition , have been studied during winter time. The rhizosphere temperature is 20 ℃, 15 ℃and 7 - 11 ℃, respectively. The results showed that flower yield and quality were advanced by rhizosphere heating significantly , compared with no heating treatment . When it was heated to 20 ℃ at the rhizosphere , the increments of flower yield and stem length were 71. 34 % , 19. 14 % , respectively. The increased flower yield of rhizosphere heating were quite different among different cultivars of Gerbera tested. The most increments of flower yield and stem length were 90. 98 % , 28. 32 % , respectively.
