The appearance of potassium sulfate is white or colored crystal or granule, which is characterized by low moisture absorption, is not easy to agglomerate when stored, and is easily soluble in water. Suitable for a variety of crops, can be used as base fertilizer, top dressing, and top dressing. Potassium is generally adsorbed by the soil and will not be lost. However, the principle of “small meals†should be adopted on sand with poor fertility. Generally used in potato, melon and other potassium crops, the best effect. The appearance of potassium chloride is white or light yellow crystal, sometimes containing iron salts in red. Soluble in water, it is a high-soluble quick-acting potash. As basal fertilizer, fertilizer use, appropriate use of relatively small potassium sulfate, a special focus on chlorine sensitive crops such as grapes, watermelon, potatoes, sweet potatoes, tomatoes, peppers and other crops used with caution to avoid "harmful chlorine." Further, potassium chloride saline soil does not apply, but where the green potassium chloride ions promote photosynthesis and fiber formation effect on cotton, hemp and other fiber crops are particularly suitable. To accurately distinguish and use these two kinds of fertilizers, it should be noted that when purchasing potassium fertilizer, first look at whether the appearance meets the above explanation; secondly, look at the bag identification and implementation standards, and the potassium sulfate is executed by the original Ministry of Chemical Industry HG/T3279-1990 The implementation of potassium chloride is international GB6549-86 ; in addition, the price cannot be considered simply, mainly depending on the nutrient content.
LED street light has revolutionized outdoor lighting, offering numerous advantages over traditional lighting technologies. With their energy efficiency, long lifespan, and superior performance, LED street lights have become the preferred choice for illuminating roads, pathways, and public spaces. However, not all Outdoor Adjustable Street Light Fixture is created equal. There are various classifications and types of LED street lights available in the market, each designed to meet specific requirements and deliver optimal lighting solutions.One of the primary classifications of Outdoor LED Street Lights is based on their wattage or power consumption. LED street lights are available in a range of wattages, typically ranging from 20 watts to 400 watts or more. The wattage determines the brightness or lumen output of the Outdoor LED Street Light, and different wattages are suitable for different applications. Lower wattage LED street lights are often used for residential areas, pedestrian pathways, or small parking lots, while higher wattage lights are more suitable for major roads, highways, and large parking areas.
Another important classification of LED street lights is based on their optical design and light distribution patterns. LED street lights are available in various beam angles, including wide, medium, and narrow beams. The beam angle determines the spread and concentration of light, allowing lighting designers to choose the most appropriate option for specific applications. For example, a wider beam angle may be preferred for illuminating large open spaces, while a narrower beam angle may be more suitable for focusing light on specific areas or reducing light pollution.
