- 生物分解性フィルム (BF) は潜在的な代替品ですが,北東中国の黒土米システムでの有効性は十分に研究されていません.
研究 の 目的:
- PEフィルムとフィルムなしのコントロール (CK) に対して,異なる分解率 (45,60,80日) の3つのBFの性能を評価する.
- これらのマッチング材料が土壌の熱水条件,米の成長,収穫量,穀物の品質,灌用水の利用効率 (IWUE),土壌の炭素と窒素の動態に与える影響を評価する.
主な方法:
- フィールド実験では,PEフィルム,3つのBF (BF45,BF60,BF80) とコントロール (CK) の5つの処理を比較した.
- 測定には,土壌温度,土壌水分,米の収穫量,穀物の品質パラメータ,IWUE,土壌有機炭素 (SOC),総窒素 (TN),総炭素 (TC) が含まれていた.
主要な成果:
- すべてのマッチング処理は,CKと比較して土壌の温度と水分を上昇させた.
- PEフィルムにより,土壌の温度が最も高くなり,BFは同等またはわずかに低い温度を示した.
- PEとBFは,CKと比較して,米の収穫量とIWUEを大幅に増加させた. BF80は,BFの中で最大の可能性を示しました.
- BFは土壌の有機窒素,SOC,TNを改善し,BF80はTNとTCを減少させたPEとは異なり,最も顕著なポジティブな効果を示した.

The Nitrogen Cycle
60.7K
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...

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:

The Carbon Cycle
44.1K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

Carbon Skeletons

Life on Earth is carbon-based, as all macromolecules that make up living organisms contain carbon atoms. All organic compounds have a carbon backbone. Each carbon atom is tetravalent and can bond with four other atoms, making it an extraordinarily flexible component of biological molecules. Because carbon’s valence electrons are stable, it rarely becomes an ion. As the carbon chain increases in length, structural modifications such as ring structures, double bonds, and branching side...

The Periodic Table

As early chemists discovered more elements, they realized that various elements could be grouped by their similar chemical behaviors. One such grouping includes lithium (Li), sodium (Na), and potassium (K). All of these elements are shiny, conduct heat and electricity well, and have similar chemical properties. A second grouping includes calcium (Ca), strontium (Sr), and barium (Ba), which also are shiny, good conductors of heat and electricity, and have chemical properties in common. However,...
