First, it can provide rich nutrients for the soil. The young stems and leaves of various green manures are rich in nutrients. Once they are decomposed in the soil, they can greatly increase the organic matter and nitrogen, phosphorus, potassium, calcium, magnesium and various trace elements in the soil. Every thousand kilograms of green manure, generally available for nitrogen 6.3 kilograms, phosphorus 1.3 kilograms, potassium 5 kilograms, equivalent to 13.7 kilograms of urea, 6 kilograms of superphosphate and 10 kilograms of potassium sulfate. The roots of green manure crops are well developed. If there are 1,000 kilograms of fresh grass on the ground, there will be 150 kilograms of underground roots, which will increase soil organic matter, improve soil structure, and increase soil fertility. Legume green manure crops can also increase nitrogen in the soil. It is estimated that 2/3 of the nitrogen in legume green manure comes from the air. Second, can make the soil insoluble nutrient conversion, in order to facilitate the absorption and utilization of crops. The secretion of green manure crops during the growth process and the organic acids produced by decomposition after overturning can convert the insoluble P and K in the soil to the availability of phosphorus and potassium for crops. Third, can improve the physical and chemical properties of the soil. After the green manure is turned into soil and continuously decomposed under the action of microorganisms, in addition to releasing a large amount of effective nutrients, humus is also formed. The combination of humus and calcium enables the soil to be cemented into agglomerate structure. The soil with aggregate structure is loose, breathable, and retains water. Maintaining strong fertility, regulating the performance of water, fertilizer, gas, and heat is conducive to crop growth. Fourth, to promote soil microbial activity. After the green manure is applied to the soil, fresh organic energy substances are added, so that the microorganisms can rapidly reproduce and the activity can be enhanced, and the formation of humus and the efficient use of nutrients can be accelerated, and the soil can be matured.
For our uv light application
1.The uv light use for HVAC system
This products emits germicidal ultraviolet(UV-C) lights to help disinfect the cooling coil,drain pan,and internal surfaces of HVAC systems for improved indoor air quality.,also use for applications in the food processing and beverage industries as well as medical and laboratory sterilization applications.
2.The uv light use in kitchen
Ultraviolet (UV) treatment is also being incorporated into new kitchen ventilation
design. UV light breaks down grease molecules into smaller harmless compounds
carbon dioxide and water vapor, which are carried out with the exhaust airflow.
Mainly use High Ozone UV Lamp, we have GPH1630T5VH/HO
GPH1630T5VH,GPH1680T5VH/HO,GPH1680T5VH,GPH865T5VH/HO,GPH865T5VH
3.The uv light use in water treatment.
