摘　　要：以飞寒樱为研究对象,研究大量元素水溶肥、中量元素水溶肥和微生物菌剂(艾加生物公司)等产品的不同用量和配施处理对樱花开花及叶绿素含量的影响。结果表明,不同处理对樱花开花各指标及叶绿素含量的促进效果是不同的。对芽鳞开裂率、露红率、产生花苞率、初花率、开花率、平均每株开花数和叶片叶绿素含量等指标进行归一化处理,采用主成分分析法(PCA)构建樱花开花及叶绿素含量的评估模型,结果表明,促进樱花开花及叶片叶绿素含量较佳的肥料配施方案为大量元素水溶肥100 g·株^(-1),微生物菌剂50 mL·株^(-1),中量元素水溶肥10 g·株^(-1)。Taking oriental cherry as the research object,this study has investigated the effects of different dosages and combinations of macroelement water-soluble fertilizer,secondary element water-soluble fertilizer,and microbial inoculants(Aijia Biological Company)on flowering and chlorophyll content.The results have indicated that different treatments have different promoting effects on various indicators of flowering and chlorophyll content.We have normalized the indicators of bud scale cracking rate,red exposure rate,flower bud production rate,initial flower rate,flowering rate,average number of flowers per plant,and leaf chlorophyll content and used principal component analysis(PCA)to construct an evaluation model for flowering and chlorophyll content.The results have showed that the optimal fertilizer combination for promoting flowering and chlorophyll content in leaves was macroelement water-soluble fertilizer of 100 g per plant,microbial inoculants of 50 mL per plant,and secondary element water-soluble fertilizer of 10 g per plant.
