在第八届花博会室内展区中,一个由澳大利亚木本切花布置的展位特别引人注目,他们一改以百合、红掌和蝎尾蕉等草本切花为主调的高等级插花的面貌,而是以澳大利亚本土的帝王花、蒂罗花、针垫花、木百合、蜡花等高档木本切花为主调的插花来布置展位,令人耳目一新。澳大利亚木本切花大都来自能适应干旱气候条件的植物,因止瓶插期都很长,而且容易养护,有些品种甚至可维持3个月。 相似文献

Application of a 5-day dark treatment during the most active period of shoot growth of the tulip induced rapid elongation of the first internode. This treatment has been shown to be potentially useful for obtaining taller tulips for commercial cut-flower production. This treatment does not affect either the flowering date or other plant characteristics such as leaf length, flower length and colour, stem diameter or the total plant shape.Neither small light leaks, short periods of lighting, nor slight temperature fluctuations lessened the dark effect. Chemical treatments such as an application of gibberellins may also be combined with dark treatment as a forcing technique. 相似文献

施肥对三种切花百合钾素吸收动态的影响 总被引：1，自引：0，他引：1
通过盆栽土培试验方法,研究了施肥与不施肥(对照)条件下东方百合、麝香百合和亚洲百合3个切花百合品种的钾素吸收规律.结果表明:随着生育期进展,各品种的切花百合地上部各器官含钾量均逐渐降低,地下部器官根和鳞茎则依品种和施肥的不同而表现出差异.鳞茎中的钾素支撑切花百合的前期地上部生长的钾素需求,经历的时间3个品种基本一致,均为47 d.钾素快速吸收期品种之间存在差异,东方百合由花芽分化至切花,历时81 d;麝香百合由花芽分化至切花,历时50 d;由亚洲百合10月6日至切花,历时25 d.施肥均提高了3个品种后期整株的钾积累量,但出现时期因品种而不同,东方百合最早、麝香百合次之、亚洲百合最迟. 相似文献

Sustainable agriculture has become a concern, due to the pressures of the “energy crisis” and issues of “environmental protection”. The use of organic fertilizer made from agricultural waste regenerates natural resources and reduces the consumption of fossil energy as well as phosphorus (P) and potassium (K) deposits. There is scant information available concerning the use of organic fertilizer as the sole source of nutrients in flower production, especially in the cultivation of flowers in a soilless condition. The objective of this study was to develop an organic fertilization management system to replace the chemical fertilization management of the cut flower production of Anthurium andreanum Lind. cultivated under soilless conditions. Four fertilization treatments were carried out consisting of two chemical fertilizers [controlled release fertilizer (CRF) and a chemical nutrient solution (CNS)], and two organic fertilizers [pea and rice hull compost (PRHC) and cattle dung with tea leaf residue compost (CDTC)]. The effects of the various fertilizations on A. andreanum were evaluated based on plant growth, nutrient uptake, and cut flower quality during the 1-year experimental period. The results show that the growth, yield, and cut flower quality of plants receiving PRHC were the same as those receiving CNS and CRF, indicating that PRHC can substitute for CRF and CNS as a nutrient source for cut flower production of A. andreanum cultivated in soilless condition. The plants that received the CNS and PRHC treatments had a significantly increased leaf number and new leaf growth area than those that received the CRF and CDTC treatments. The plants receiving the CDTC showed the lowest increase in leaf area and number of flowers. The retardant growth of plants treated with CDTC has been explained as being due to less carbon (C) being assimilated, most likely as the result of an insufficient supply of nitrogen (N) and manganese (Mn) toxicity. The petiole and peduncle length of the plants receiving the CRF were the shortest, which might be due to the low level of potassium (K) accompanying the magnesium (Mg) deficiency. Even though there were significant differences in the N and K concentrations of the plants among the different treatments, no significant differences were observed in the cut flower quality. In short, the organic fertilizer PRHC can meet the nutrient requirements of A. andreanum cultivation for the cut flower production under soilless conditions. 相似文献

The main object of the investigation was to attempt the separation of effects of photoperiod and total incident light energy in controlling flower initiation in the glasshouse carnation, variety White Sim.Low light intensities delayed flower initiation. The delay was associated with reduced rates of growth in terms of dry weight, reduced rates of leaf initiation and increased number of leaves formed below the flower. Short days also delayed flower initiation and increased the number of leaves formed below the flower. Photoperiod, however, had no appreciable effect on growth in terms of dry weight or on rates of leaf initiation, but internode length was greater in long days than in short days. A period of illumination given in the middle of the night was more effective in promoting flower initiation than an equivalent period given to extend the day. Internode length was similar in these treatments. Effects of night temperature were less consistent than those of light intensity or daylength but, under most of the conditions tested, high night temperatures (minimum 65° F. (18° C.)) delayed flower initiation and increased the number of leaves formed below the flower. Low temperature treatment of plants at 40° F. (4.5° C.) for one month promoted subsequent flower initiation and reduced the number of leaves formed below the flower. 相似文献
