Effects of biodegradable Film Mulching on Yield, Grain Quality, and Soil Metabolic Characteristics of Water-Saving and Drought-Resistant Rice

ABSTRACT: This study investigates the metabolic changes in paddy soil subjected to three different rice cultivation treatments: non-flooded unmulched cultivation (UM), non-flooded biodegradable film mulching cultivation (BM), and traditional flooding cultivation (TF). Untargeted metabolomics analysis was performed on rhizosphere soil samples collected at harvest stage using liquid chromatography-tandem mass spectrometry (LC-MS/MS) in both positive and negative ionization modes. Raw data were acquired on a SCIEX mass spectrometer (wiff format). Soil metabolites were annotated using the Human Metabolome Database (HMDB) and KEGG pathways. This study is part of a larger investigation into the effects of biodegradable film mulching on yield, grain quality, and soil metabolic characteristics of water-saving and drought-resistant rice (variety Hanyou 73).
