Trichoderma longibrachiatum-based fertilizers promote Phoebe bournei seedling growth by regulating plant physiology, nutrients utilization, and the rhizosphere microbial community.

ABSTRACT:

Background

Phoebe bournei, a rare and endangered plant species in China, exhibits low seedling survival rates and slow growth. Although Trichoderma longibrachiatum-based organic fertilizer is beneficial, it remains unclear whether it can reduce chemical fertilizer dependence while promoting P. bournei growth. Here, P. bournei seedlings were treated with a combination of T. longibrachiatum-based organic fertilizer and reduced chemical fertilizer (designated as the HF treatment). This study was employed to investigate the synergistic mechanisms underlying growth promotion.

Results

Plant physiology, pedology, and amplicon sequencing were used to evaluate the growth of P. bournei seedlings. The HF treatment optimally promoted P. bournei seedling growth, with a 39.8% increase in
