摘要

为解析间作相生相克作物对香葱生长及抗性的作用机制，设置C：香葱单作处理、F：相克处理组合（香葱/豌豆间作）和H：相生处理组合（香葱/番茄间作），比较分析香葱间作不同作物对根系内生微生物群落组成的影响。结果显示：unclassified_f_Xanthomonadaceae、独岛杆菌属（

Dokdonella

）、黄杆菌属（

Flavobacterium

）、unclassified_f_Alcaligenaceae、德沃斯氏菌属（

Devosia

）细菌是香葱间作相生相克作物体系下香葱根系排名前5的共有优势内生细菌属；同时，嗜酸菌属（

Acidovorax

）细菌是相克处理组合：香葱/豌豆间作体系下，香葱根系中特有的优势内生细菌属。单镰刀菌属（

Fusarium

）、炭疽菌属（

Colletotrichum

）、

Plectosphaerella

、unclassified_o

_Helotiales

、新赤壳属（

Neocosmospora

）真菌是香葱间作相生相克作物体系下香葱根系排名前5的共有优势内生真菌属；赤霉属（

Gibberella

）和

Acrocalymma

属真菌是相生处理组合香葱/番茄间作体系下香葱根系中特有的优势内生真菌属；

Dactylonectria

和漆斑菌属（

Myrothecium

）真菌是相克组合处理（香葱/豌豆）间作体系下香葱根系中特有的优势内生真菌属。结果表明，香葱间作不同作物塑造了香葱根系相异的内生微生物群落，香葱间作相生作物体系中，香葱根系中形成了具有促进作物生长、提高作物抗性功能的内生微生物群落；而香葱间作相克作物体系中，香葱根系中形成了以病原微生物为主体的内生微生物群落，这可能是香葱间作不同作物产生相生相克现象的重要机制之一。

Abstract

Treatments including C （chives monoculture）， F （intercropping chives and pea）， and H （intercropping chives and tomato） were set to analyze the mechanism of intercropping allelopathic crops on the growth and resistance of chives. The effects of intercropping different crops with chives on the composition of endophytic microbial communities in the root system of chives were compared. The results showed that unclassified_f_Xanthomonadaceae

， Dokdonella， Flavobacterium，

unclassified_f_Alcaligenaceae

and

Devosia

were the top 5 dominant endophytic bacterial genera in the root system of chives under the intercropping allelopathic crops.

Acidovorax

bacteria were the allelopathic combination. There was the dominant endophytic bacterial genus unique to the root system of chives under F （intercropping chives and pea）.

Fusarium， Colletotrichum， Plectosphaerella，

unclassified

Helotiales，

and

Neocosmospora

fungi were the top 5 dominant endophytic fungi genera in the root system of chives under the intercropping allelopathic crops.

Gibberella

and

Acrocalymma

fungi were the dominant endophytic fungi unique to the root system of chives under H （intercropping chives and tomato）.

Dactylonectria

and

Myrothecium

fungi were the dominant endophytic fungi unique to the root system of chives under F （intercropping chives and pea）. It is indicated that intercropping chives with different crops shaped the composition of endophytic microbial communities in the root system of chives. In the intercropping system of chives， an endogenous microbial community with the functions of promoting crop growth and enhancing crop resistance is formed in the root system of chives. In the intercropping system of chives， an endophytic microbial community dominated by pathogenic microorganisms is formed in the root system of chives， which is one of the important mechanisms for intercropping allelopathic crops with chives as well.
