概括
多种类的剑与豆类和草药可以减少草原的氧化 (N2O) 排放. 一种多年生麦草,红叶三叶草和强化植物混合物 (PRP) 改善了干物质产量和土壤健康,同时降低了N2O排放.
科学领域:
- 农业科学 农业科学
- 环境科学 环境科学
- 农业学是一种农业学.
背景情况:
- 草原生态系统是温室气体 (GHG) 排放的重要来源,特别是氧化 (N2O).
- 与草原单一种植相比,多种类的剑 incorporating 豆类和各种草药提供了减轻N2O排放和改善土壤健康的潜力.
- 保持或提高干物质 (DM) 产量对于畜牧业生产至关重要.
研究的目的:
- 为了评估日益复杂的多种剑对干物质产量,料质量,温室气体排放 (N2O和甲) 和土壤健康的影响.
- 为了比较这些剑与受精的多年生麦草单种植.
主要方法:
- 进行了为期一年的情形研究,比较了五种剑草类型:多年生麦草和红三叶草 (PR),PR + 增强植物 (PRP),PR + 增强植物 + 鸟脚三叶草 (PRPB),PR + 增强植物 + 鸟脚三叶草 + 烧 (PRPBB) 和受精多年生麦草 (Pfert).
- 干燥物质的产量和质量在两次切割后被评估.
- 在整个研究过程中,对氧化和甲排放进行了监测.
主要成果:
- 在更复杂的剑 (PRP,PRPB,PRPBB) 中,干物产量最高,PRP的产量明显高于Pfert和PR.
- 与受精多年生麦草单种植 (Pfert) 相比,所有多种剑的平均N2O排放量都明显较低.
- PRP刀剑显示了更高的代谢能量和持续的土壤健康指标,包括物理结构和土种群.
结论:
- 多种多年生草,红三叶草和植物 (PRP) 的多种草可以比受精多年生草单一栽培获得更高的干物质产量.
- 通过减少N2O排放,PRP刀具有助于缓解气候变化,并通过改善土壤健康和料质量,为乳制品系统提供适应效益.

The Roles of Bacteria and Fungi in Plant Nutrition
34.8K
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.

Overview of Nitrogen Metabolism
7.8K
Nitrogen is a very important element for life because it is a major constituent of proteins and nucleic acids. It is a macronutrient, and in nature, it is recycled from organic compounds and stored in the form of ammonia, ammonium ions, nitrate, nitrite, or nitrogen gas by many metabolic processes. Many of these metabolic processes are carried out only by prokaryotes.

The Nitrogen Cycle
51.3K
Nitrogen atoms, present in all proteins and DNA, are recycled between abiotic and biotic components of the ecosystem. However, the primary form of nitrogen on Earth is nitrogen gas, which cannot be used by most animals and plants. Thus, nitrogen gas must first be converted into a usable form by nitrogen-fixing bacteria before it can be cycled through other living organisms. The use of nitrogen-containing fertilizers and animal waste products in human agriculture has greatly influenced the...

Key Elements for Plant Nutrition
18.6K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

The Soil Ecosystem

Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:

Overview of Metabolism
29.2K
Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...
