概括

堆肥的叶子和院子废物 (LAT) 改善了植被机构的土壤肥力. 生物固体 (BAT) 增强了芽生长,但阻碍了根部的发育,而木 (MAT) 则缺乏足够的气来培育草.

科学领域:

环境科学环境科学
土壤科学土壤科学
园艺园艺园艺园艺

背景情况:

干扰土壤和人工地表土通常缺乏成功植被建立的特性.
城市有机废物产品,如土,堆肥和生物固体,被用作改善土壤状况的修正物.
评估土壤特性 (pH,可溶盐,营养物质) 和植物生长对于确定修改效果至关重要.

研究的目的:

调查三种有机修订物 (木,堆肥的叶子和院子废物,生物固体) 对土壤肥力,草生长和营养损失的影响.
为了比较这些修改与对照 (未经修改的土壤) 的有效性.

主要方法:

制造的表土被用作控制和修改处理的基础.
处理包括未经修改的控制 (CUT),木 (MAT),堆肥的叶子和院子废物 (LAT) 和生物固体 (BAT).
监测了土壤特性 (pH,C:N比率,NPK,可溶盐) 和植物生长 (根和芽).

主要成果:

堆肥的叶子和院子废物 (LAT) 显著改善了土壤的肥力,营养含量 (N-P-K),并保持了有利的pH和可溶盐水平.
生物固体 (BAT) 促进了芽生长,但对根部发育产生了负面影响,表明过度的应用.
由于含含量低,单独的木覆盖面 (MAT) 不足以用于草草的建立.

结论:

堆肥的叶子和院子废物是改善土壤肥沃性和支持草草的有利修正案.
生物固体可以作为一个有效的肥,如果应用在推的速度,以防止根抑制和泄漏.
木需要额外的补充,以便在干扰的土壤中成功建立草草.

关键词:

The Soil Ecosystem

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:

Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Overview of Nitrogen Metabolism

Overview of Nitrogen Metabolism

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 largest pool of nitrogen available in the terrestrial ecosystem is gaseous nitrogen (N2) from the air, but this...

The Roles of Bacteria and Fungi in Plant Nutrition

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.
