熟石灰-20KGhydrated lime
熟石灰（氫氧化鈣）在農業中有多種重要用途：Ca（OH）2
適用: 農業,
定期化驗, 品質達標可靠
改良土壤：熟石灰能中和酸性土壤，提高pH值，改善土壤結構，促進植物生長。
提供營養：它為植物提供鈣元素，有助於根系發育和果實形成。熟石灰在改良酸性土壤中的具體步驟如下：
準備材料：
將熟石灰（氫氧化鈣）磨碎，確保其細度達到80%-100%通過20-40目篩。
混合：
將磨細的熟石灰與碳酸鈣按照重量比3:0.8至1.2充分混合，製成酸性土壤改良劑。
施用：
在整地前，將混合好的改良劑均勻施加於土壤表層。
翻耕：
將施用的改良劑翻耕入耕作層（0-20cm），確保與土壤充分混合。
用量控制：
每公頃施用量建議為3500-4000kg，根據土壤酸度和作物需求進行調整。
監測效果：
施用後定期檢測土壤pH值，通常在30天內可將pH值從4.0提高至6.0-6.5，達到適宜作物生長的範圍。
通過以上步驟，熟石灰能夠有效改善酸性土壤的性質，提高土壤的肥力和作物的生長環境。
防治病害：熟石灰可用於消毒土壤，降低病原菌和害蟲的數量。
水質處理：在水稻田等濕地中，熟石灰能改善水質，促進有益微生物繁殖。

Calcium hydroxide, commonly known as slaked lime, has several important applications in agriculture, particularly in improving soil quality and health. Here’s an overview of its uses and the specific steps for its application in ameliorating acidic soils:
Key Uses of Calcium Hydroxide in Agriculture
Soil Improvement: Calcium hydroxide neutralizes acidic soils, raising the pH and enhancing soil structure, which promotes better plant growth.
Nutrient Supply: It provides essential calcium, aiding root development and fruit formation.
Disease Control: It can disinfect soil, reducing pathogens and pests.
Water Quality Improvement: In rice paddies and wetlands, it helps improve water quality and supports beneficial microbial growth.
Steps for Amending Acidic Soils with Calcium Hydroxide
Preparation of Materials:
Grind calcium hydroxide to a fine powder, ensuring it passes through a 20-40 mesh sieve (80%-100% fineness).
Mixing:
Combine the powdered calcium hydroxide with calcium carbonate in a weight ratio of 3:0.8 to 1.2 to create a soil amendment mix.
Application:
Before tilling, evenly spread the mixed amendment on the soil surface.
Incorporation:
Till the amendment into the topsoil (0-20 cm depth) to ensure thorough mixing with the soil.
Rate Control:
The recommended application rate is 3500-4000 kg per hectare, adjusted based on soil acidity and crop requirements.
Monitoring Effects:
Regularly test soil pH after application; typically, pH can increase from 4.0 to between 6.0 and 6.5 within 30 days, creating a suitable environment for crop growth.
By following these steps, calcium hydroxide effectively improves the properties of acidic soils, enhancing fertility and creating a conducive environment for plant development.
