百子莲无土栽培营养液配方的研究

为提高百子莲的生产效率和花朵品质,降低百子莲的生产成本,促进百子莲的推广应用。本研究以两年生百子莲组培苗为材料,以无土基质配比组合(玉米秸秆∶百子莲腐叶∶炉渣=1∶2∶1)为栽培基质。试验营养液是在改良Hoagland营养液配方基础上,分别从浓度、铁盐含量和pH三个因素的三水平入手,按正交组合方法进行设计。从各营养液对百子莲形态及生理等指标的影响进行对比分析。结果表明:pH 6.5的0.5倍浓度添加1.2倍铁盐含量的无土基质栽培百子莲植株生长健壮,干物质积累迅速,抗外界胁迫能力强,是百子莲无土基质栽培的最佳的营养液处理配方。

The nutrient formula for soilless cultivation of Agapanthus praecox ssp.orientalis cv.Big Blue

To improve the production efficiency and the quality of flower,reduce the cost of production and promote the process of popularization and application of Agapanthus praecox,we chose 2-year-old seedlings of Agapanthus praecox from tissue culture as the material and screened the combination of soilless media in pre-experiments(corn stalk∶rotted leaf of Agapanthus∶slag=1∶2∶1) as growing media.Based on the modified Hoagland nutrient solution,the test was designed by the orthogonal combination method from the three factors of the concentration,ferric salt and pH at three levels respectively.The effects of different nutrient solution on the morphology and physiological index of Agapanthus praecox were analyzed.The results indicated that Agapanthus praecox poured in the nutrient solution composed of 0.5 times concentration of Hoagland solution added with 1.2 times of ferric salt at pH 6.5 grew robustly,showing rapid accumulation of dry matter and strong resistance to outside stress,which was supposed to be the best formula for soilless cultivation of Agapanthus praecox ssp.Orientalis cv.Big Blue.
