Intercropping grapevine with <i>Solanum nigrum</i> enhances their cadmium tolerance through changing rhizosphere soil microbial diversity.

ABSTRACT:

Introduction

Cadmium (Cd), a toxic heavy metal, has increasingly impacted vineyard soils and grapevine (Vitis vinifera) production in recent years. Intercropping with the hyperaccumulator plant Solanum nigrum has emerged as a promising strategy to improve soil health and increase plant resilience to the Cd-contaminated soil.

Methods

This study investigated the effects of intercropping grapevine with S. nigrum (IntVVSN) on the soil enzyme activity and microbial community.

Results

Compared with the monocultures of S. nigrum and grapevine, IntVVSN increased the activities of soil sucrase, soil urease, and soil cellulase, and decreased the activities of soil amylase, and soil neutral phosphatase. The microbial community in IntVVSN showed higher
