To explore the effects of common silicon fertilizer and nano-silicon fertilizer on the population structure of endophytic fungi in flue-cured tobacco,Yunyan 99 was used as test material, common silicon and nano-silicon were sprayed at vigorous growth,budding and dome stages.The treatments were set as follows: CK (water), T5 (common silicon,0.17 kg/hm2), T8 (nano-silicon,0.32 kg/hm2).The effects of different silicon fertilizer on the diversity, composition, structure, chemical composition and aroma substance of endophytic fungi in flue-cured tobacco were studied. Compared with CK, T5 and T8 treatment could effectively improve the community diversity,composition, structure and the content of chemicals and aroma substances. Compared with CK, the diversity of endophytic fungi increased under T8 treatment and decreased under T5 treatment.Compared with CK, the relative abundance of Basidiomycota under T5 and T8 increased by 58.14% and 37.35%, respectively,at the same time, the relative abundance of Flobasidium increased by 113.17% and 417.07%, respectively.Among them, T8 treatment increased the species of endophytic fungi, among which,31 species were more than CK treatment. The correlation analysis was based on chemical composition, aroma substances of tobacco leaves and endophytic fungal community composition.The contents of nicotine,soluble protein,Maillard reaction products and aroma substances were significantly related to the community composition of endophytic fungi in tobacco leaves. The diversity of endophytic fungi in tobacco leaves could be increased by spraying nano-silica fertilizer on leaf surface,and the content of chemicals and aroma substances of tobacco could be changed.It is meaningful for human to produce high quality flue-cured tobacco. 相似文献

研究不同比例的蚯蚓粪有机无机复混肥对土壤有机碳含量以及烤烟品质的影响,为陕南烟区土壤改良和施肥管理提供科学依据。田间试验设5个处理,以CK(单施氮磷钾复合肥)为对照,设置4种不同比例的有机无机复混肥处理即OIF1(含蚯蚓粪1 800 kg/hm2)、OIF2(含蚯蚓粪2 400 kg/hm2)、OIF3(含蚯蚓粪3 000 kg/hm2)、OIF4(含蚯蚓粪7 500 kg/hm2),测定成熟期土壤的有机碳含量、分布以及烤烟品质特性指标。结果表明,蚯蚓粪有机无机复混肥可显著提升有机碳含量,OIF2处理对全土有机碳含量、>1.00～2.00 mm、>0.50～1.00 mm、≤0.25 mm粒径的团聚体有机碳含量提升效果显著。适宜比例蚯蚓粪复混肥对烤烟物理特性、经济性状、化学成分协调性及烤烟香气物质均有不同程度的提升作用,OIF2的经济效果指数(ECI)值最大,产量、产值、均价与上等烟比例均有显著提升,各处理的糖碱比、氮碱比均在适宜值范围内,钾含量以OIF2处理最高,OIF3处理和OIF2... 相似文献
