覆盖种植介导了叶系微生物健康和水稻产量的调节
Cover Cropping-Mediated Regulation of Phyllosphere Microbial Health and Rice Yield.
摘要(中文译文)
尽管覆盖作物是可持续农业的重要组成部分，但其对水稻病害管理和产量的具体影响仍知之甚少。本项为期2年的田间研究（2023—2024年）评估了冬季覆盖作物［冬季休耕、意大利黑麦草（Italian ryegrass，IR）和光叶紫花苕（smooth vetch，VV）］对夏季水稻叶际微生物群落组装及产量的影响。与休耕相比，VV和IR处理下的蒸腾速率分别提高了31.6%和25.3%，净光合速率分别提高了25.0%和23.9%（P < 0.05）。覆盖作物富集了潜在有益类群（如 和 ），并降低了潜在病原菌库 的相对丰度。此外，VV和IR提高了功能性真菌属（ 、 和 ）的丰度。与休耕相比，VV和IR处理分别使籽粒产量提高了26.77%和21.26%。推荐采用VV和IR进行冬季覆盖种植，以实现可持续的高产水稻生产。
Abstract
Although cover crops are integral to sustainable agriculture, their specific impacts on rice () disease management and yields remain poorly understood. This 2-year field study (2023-2024) evaluated the effects of winter cover crops [winter fallow, Italian ryegrass (, IR), and smooth vetch (, VV)] on summer rice phyllosphere microbial assembly and yield. Compared to fallow, transpiration rates under VV and IR increased by 31.6% and 25.3%, while net photosynthetic rates increased by 25.0% and 23.9%, respectively ( < 0.05). Cover crops enriched potentially beneficial taxa (e.g., and ) and reduced the relative abundance of , which is a potential pathogen reservoir. Furthermore, VV and IR enhanced the abundance of functional fungal genera (, , and ). Compared to fallow, the VV and IR treatments increased the grain yield by 26.77% and 21.26%, respectively. Winter cover cropping with VV and IR is recommended for sustainable, high-yield rice production.
