摘要: 以湖北省地方特色资源桃叶橙(Citrus sinensis Osbeck cv.Taoye Cheng)为材料,设置生草栽培和清耕栽培2个处理,解析生草栽培和清耕栽培对桃叶橙根际土壤、微生物群落和果实品质的影响。结果表明,生草栽培的桃叶橙根际土壤有机质含量比清耕栽培提高了23.53%;在土壤营养元素方面,生草栽培桃叶橙根际土壤的磷、钾、钙、硼和锌含量均显著高于清耕栽培,而氮、镁和锰含量均显著低于清耕栽培。生草栽培的桃叶橙根际微生物群落多样性及丰度均显著高于清耕栽培,说明生草栽培能够有效丰富桃叶橙根际的微生物群落。生草栽培能够促进桃叶橙果实的生长和维生素C的合成。相关性分析表明,桃叶橙果实的横径、纵径、单果重和维生素C含量均与RB41、Pseudomonas呈显著正相关。

Abstract: This study used the local characteristic resource Taoye Cheng(Citrus sinensis Osbeck cv.Taoye Cheng) in Hubei Province as the material, and set up two treatments of grass cultivation and clearing cultivation to analyze the effects of grass cultivation and clearing cultivation on the rhizosphere soil, microbial community, and fruit quality of Taoye Cheng. The results showed that the organic matter content in the rhizosphere soil of Taoye Cheng cultivated with grass was 23.53% higher than that of clearing cultivation;in terms of soil nutrients, the content of phosphorus, potassium, calcium, boron, and zinc in the rhizosphere soil of Taoye Cheng cultivated with grass was significantly higher than that of clearing cultivation, while the content of nitrogen, magnesium, and manganese was significantly lower than that of clearing cultivation. The diversity and abundance of the rhizosphere microbial community of Taoye Cheng cultivated with grass were significantly higher than those of clearing cultivation, indicating that grass cultivation could effectively enrich the microbial community of Taoye Cheng rhizosphere. Grass cultivation could promote the growth of Taoye Cheng fruit and the synthesis of vitamin C. Correlation analysis showed that the transverse and longitudinal diameters, single fruit weight, and vitamin C content of the fruit of Taoye Cheng were significantly positively correlated with RB41 and Pseudomonas.

Key words: grass cultivation, clearing cultivation, Taoye Cheng, rhizosphere soil, microbial community, fruit quality
