摘要
根据多年的生产实践,从科学育苗、栽培管理、售前处理和病虫害防治等方面综合总结了叶子花的规模化矮化促成生产技术措施:选择泥炭土、蛭石和黄沙按3:2:1比例混合均匀的扦插基质,采用半木质化当年生枝条,剪成5～10cm长的2～3叶节一段,沾染1%自制生根粉的扦插育苗较组培育苗成本低,成活率高;结合修剪用2～5g/L的多效唑进行叶面喷洒能有效控制生长,矮化植株;选择2.5～4.0的丁酰肼叶面喷洒和每天保持不多于11h的短日照处理,能有效促进开花;销售前全株喷洒脱50mg/L NAA可延长花期20天左右;整个生产过程加强肥水管理、温湿度控制和环境清洁能有效防治病虫害发生.
According to several years practice, comprehensively sum up measures of forcing culture technology of scale and dwarf on potted Bougainvillea as: a propagation of cuttage, which choose a mixture of 50%peat, 33% vermiculite and 17 sharp sand as cutting soil, and choose a semi-wooden shoot cut into 5~10cm length with 2~3 leaves as cuttings then touch 1% AA root powder (made by ourselves), is lower cost and higher survival rate than that of tissue culture; Bougainvillea growth can be efficaciously regulated by pruning and using 2~5g/L PP333; bougainvillea can be induced to flowers by spraying 2.5~4.0g/L B9 and administering no more 11 hours daylight every day continuously; the florescence can be more prolonged about 20 days by spraying 50mg/L NAA while selling; and prevention and cure of pest and disease, etc.
