通过增强有益的土壤微生物和营养素,薄膜-草双重覆盖显著提高了番茄的产量和生长. 这种可持续的做法可以改善土壤的特性,从而改善作物生产.

科学领域:

农业科学农业科学
土壤微生物学土壤微生物学
植物科学植物科学

背景情况:

农业料对于作物生产至关重要,但它们对土壤微生物群落的确切影响以及对番茄生长的后续影响需要进一步阐明.
了解这些机制对于优化可持续农业的土策略至关重要.

研究的目的:

调查不同覆处理 (塑料薄膜,草和双薄膜草) 对土壤特性,微生物群落组成和番茄生长的影响.
确定覆盖土壤影响土壤健康和作物产量的机制.

主要方法:

一个为期三年的实地实验,比较了塑料薄膜覆盖 (SBF),草覆盖 (SM),薄膜-草双覆盖 (SBFSF) 和对照 (CK).
系统地评估土壤特性,微生物群落结构 (细菌和真菌),以及番茄生长参数 (产量,干物质,根形态).
统计分析包括部分最小平方路径建模 (PLS-PM) 以阐明因果关系.

主要成果:

所有的覆盖处理都提高了番茄产量,SBFSF显示了最高的改善 (50.17%).
SBFSF最大限度地提高了植物干物质,根部发育,改善了土壤水分和温度调节.
SBFSF选择性地丰富了参与营养循环的有益细菌 (Firmicutes,Lysobacter,Bacillus) 和真菌 (Ascomycota,Mortierellomycota,Trichocladium),而SM和SBF增加了致病性真菌.
护对土壤有机碳,总,可用的和可用的产生了积极的影响.

结论:

薄膜-草双覆盖 (SBFSF) 是一种优秀的农业实践,可以提高番茄的产量和生长.
覆盖实践调节土壤微生物群落和属性,间接影响作物表现.
这些发现支持优化土技术,以实现可持续农业和改善土壤健康.

The Roles of Bacteria and Fungi in Plant Nutrition

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Microorganisms in Agriculture and Food industry

Microorganisms play a crucial role in agriculture and the food industry, contributing to soil fertility, crop protection, and food production. Their functions range from nitrogen fixation and biopesticide production to fermentation and food preservation, making them indispensable to sustainable farming and food safety.Role in AgricultureNitrogen-fixing bacteria, such as Rhizobium (symbiotic) and Azotobacter (free-living), convert atmospheric nitrogen into ammonia through biological nitrogen...
