Sowing depth significantly affects ginger (Zingiber officinale Roscoe) yields, and sowing depth can affect rhizosphere community structure through root exudates. However, the relationship between the reaction process in root zone and ginger rhizome development is unclear. In this study, we investigated the rhizome and root development and rhizosphere environment at different sowing depths (2 cm (SD2), 5 cm (SD5), and 10 cm (SD10)). It was found that SD10 significantly increased ginger yield, which is related to the development of vascular bundles and the expression of aquaporin. PLS-PM analysis found that root length, root absorption capacity, and soil enzymes have the strongest correlation with yield, while root diameter is negatively correlated with yield. Under SD10, the increase of auxin and ethylene content together with the expression of ARF7, LBD16, and PIN1 promoted the development of lateral roots. In addition, SD10 increased the secretion of root organic acids, amino acids, and carbohydrates, which in turn promoted the development of rhizosphere bacteria. The promotion of SD10 on nitrogen cycle and nitrogen fixation ability in turn promoted the development of ginger.

播种深度显着影响生姜（ Zingiber officinale Roscoe）产量，播种深度可通过根系分泌物影响根际群落结构。然而，根区反应过程与生姜根茎发育之间的关系尚不清楚。在本研究中，我们调查了不同播种深度（2 cm（SD2）、5 cm（SD5）和10 cm（SD10））下的根茎和根发育以及根际环境。研究发现SD10显着提高生姜产量，这与维管束的发育和水通道蛋白的表达有关。 PLS-PM分析发现根长、根吸收能力和土壤酶与产量的相关性最强，而根直径与产量呈负相关。 SD10下，生长素和乙烯含量的增加以及ARF7、LBD16和PIN1的表达促进了侧根的发育。此外，SD10还增加了根部有机酸、氨基酸和碳水化合物的分泌，从而促进了根际细菌的发育。 SD10对氮循环和固氮能力的促进反过来又促进了生姜的发育。
