摘要
就影响盆栽八仙花促成栽培花期和品质的因素进行了研究和探讨,试验结果认为选择早花品种及2 a生苗龄是保证准确调控促成栽培花期的关键;其次种苗的营养状况、花芽分化的状态、不同品种的低温需冷量及催花期的温度和光照是影响八仙花促成栽培花期和品质的重要因素。不同品种所需低温量为Leuchtfeuer(红色)44 d,Lavbla(蓝色)和Adria(粉色)37 d,Snowball(白色)30 d。为缩短八仙花冷藏周期,为促成栽培后期提供足够的生长时间,保证定时、准确上市提供参考。
The factors which influencing blooming stage and qualities of potting Hydrangea macrophylla Ser. in forcing culture were investigated in this paper. The results are as following： firstly, the varieties with early flower and the seedling cultivated 2 years are the key factors. Secondly, the main factors also include nutrition condition of the seedling , state of differentiation of floral bud, chilling requirement of the varieties, the temperature and illumination of flower induction and so on. Chilling requirement for different varieties is Leuchffeuer with 44d; Lavbla and Adria with 37d; Snowball with 30d respectively. So that the cold storage period and commerce time could be decided exactly.
