| 摘 要： | 为探讨从不同品种菊花根际土壤中分离的两株芽孢杆菌对茶用菊生长和品质的影响,以茶用菊红心菊为试验材料,研究对照(CK)、接种解淀粉芽孢杆菌处理(Ba)、接种枯草芽孢杆菌处理(Bs)、接种解淀粉芽孢杆菌和枯草芽孢杆菌混合处理(Ba+Bs)对茶用菊红心菊各生育期生理指标的影响。结果表明,苗期菌剂对各生理指标的促生效果显著高于生长期和花期;花期时,菌剂接种处理均不同程度地促进了茶用菊红心菊收获时品质和产量的提高,其中绿原酸、木犀草苷、3,5-二咖啡酰基奎宁酸含量与CK相比平均提高20%左右,且三组接种菌剂处理之间无显著差异,而Ba+Bs处理后红心菊的黄酮含量最高,比CK提高15.64%,同时该处理红心菊的估产量也最高,比CK、Ba和Bs分别提高了152.00%、64.12%和33.61%。综上所述,在茶用菊苗期栽培土壤中混合接种解淀粉芽孢杆菌和枯草芽孢杆菌(Ba+Bs)可以显著提高红心菊外观品质、花期产量以及茶用品质。本研究结果为今后茶用菊功能微生物有机肥研发奠定了良好的基础。

| Abstract: | In order to investigate the growth promoting effect of two Bacillus strains on the tea chrysanthemum, Hongxinju was used as experimental material to study the effect of control (CK), Bacillus amyloliquefaciens inoculation treatment (Ba), Bacillus subtilis inoculation treatment (Bs), Bacillus amyloliquefaciens and Bacillus subtilis mixed inoculation treatment (Ba+Bs) on the physiological indexes of Hongxinju. The results at different growth periods showed that the promoting effect at the seedling stage were significantly better than those at the growth stage and flowering stage. The results of flowering stage showed that the quality and yield of the Hongxinju were improved after inoculated with Bacillus strains in different degrees. Compared with the CK, the contents of chlorogenic acid, luteolin and 3,5-dicaffeoylquinic acid were increased by about 20% on average, and there were no significant differences among the three inoculation treatment groups. The flavonoid content of Ba+Bs treatment were the highest, and it was increased by 15.64% compared with the CK. The estimated yield of Hongxinju treated with Ba+Bs was the highest, and it was increased by 152.00%, 64.12% and 33.61%, compared with CK, Ba and Bs trestment group respectively. In conclusion, at the seeding stage, mixed inoculation with Bacillus amyloliquefaciens and Bacillus subtilis (Ba+Bs) treatment could significantly improve appearance indexes, flowering production and tea quality of Hongxinju. The results of this study lay a good foundation for the research and development of functional microbial organic fertilizer for tea chrysanthemum. |
