LEDER technology`s LED pool light is specifically designed to replace incandescent bulbs in swimming pool underwater light fixtures. Installing a 12 Volt bulb into a 120 Volt socket may permanently damage your pool's lighting system. The brightness of colors is up to 2x brighter than other cheaper bulbs. All colors can fill the whole pool. Multiple lamps can be synchronized to change color. 16 color mode: 7 brilliant fixed colors, 9 dazzling light show press the button in the remote controller to directly select the color you want.
LED pool light is used for swimming pools, water sports fields, ocean activity areas and so on.We insist on independent design, independent research and development.LED pool light is a much required lighting solution.

Nitrogen is the “big boss†in fertilizers, with the widest range of applications and the largest application rate, so the effect is also the greatest. However, utilization is often the lowest. In order to reduce the loss of nitrogen fertilizer, the application techniques should be paid attention to. For example, ammonium fertilizer should be used in rice, especially ammonium chloride and urea. Corn, wheat and other cereal crops are preferably applied with ammonium nitride fertilizer (such as ammonium bicarbonate, ammonium sulfate, ammonium chloride, urea) or nitrate fertilizer (such as ammonium nitrate). For potato and sweet potato, ammonium nitride fertilizer should be used. Different crops have different requirements for nitrogen. Leafy vegetables, tea leaves and other crops with green leaves for harvesting purposes require more nitrogen fertilizer, while soybeans, peanuts and other legume crops need only be applied in the early stage of growth, when the nodule has not yet functioned. Nitrogen fertilizer. In summer, it is hot and rainy, and the application of ammonium nitrogen fertilizer can reduce the loss. In saline-alkaline soil areas, it is not advisable to apply ammonium chloride with more chloride ions to avoid increasing soil salinity.
The effective utilization of phosphorus is also very low, often only 25%, on the one hand because they are easily converted into insoluble state in the soil and are fixed, on the other hand, improper application, such as excessive application and not according to crop needs Amount is applied. Legume crops (soybeans, peanuts), sugar crops (beets, sugar cane), fiber crops, potato crops (potato, sweet potato), melons, and fruit trees are “his phosphorus†crops, requiring more phosphorus and increasing the effect of phosphate fertilizer. it is good. Seasonal crops can only absorb a small portion of the applied phosphate fertilizer, most of which is left in the soil for absorption and utilization by the lower crop. Therefore, in the plots with more phosphorus fertilizer, there is no need to apply phosphorus every year, and it is not necessary to apply phosphorus in the season to avoid waste.
Potassium is called the “quality element†of crop growth. The potassium content in plants generally accounts for 0.2%~4.1% of the dry matter weight, second only to nitrogen. In general, crops containing more carbohydrates, such as tobacco, potatoes, sweet potatoes, sugar beets, watermelons, fruit trees, etc., require a large amount of potassium, so they are called "hot potassium" crops. However, these potassium-producing crops have the characteristic of “avoiding chlorineâ€. If potassium chloride is applied to these potassium-free chlorine crops, it will not only affect the effectiveness of potassium, but also lead to a decline in yield and quality. Potassium chloride is also not suitable for long-term application on saline soil. It can be used as a base fertilizer or top dressing on non-chlorinated crops, but it is not suitable for seed fertilizer. Potassium sulphate is suitable for various soils and crops and can be used as base fertilizer, seed fertilizer, top dressing and foliar fertilizer.
Micro and medium elements (boron, molybdenum, silicon, sulfur, chlorine)
Rapeseed and cotton, peanuts, fruit trees, etc. belong to the favorite boron crop, which is very sensitive to boron. Boron deficiency will lead to “flowers and unrealityâ€, which seriously affects crop yield.
Molybdenum fertilizer is suitable for legume crops such as peanuts and soybeans, and cruciferous crops such as broccoli and rapeseed. Applying molybdenum fertilizer on these crops can effectively increase yield and improve quality.
Silicon is called the “fourth largest nutrient element†of rice. Applying silicon fertilizer can not only improve the plant height, effective panicle number, grain number per panicle, 1000-grain weight and other biological characteristics, but also apply silicon fertilizer to promote the thickening of rice stems. The grain weight of the grain is yellow, which enhances the ability of drought resistance and pest resistance, improves the utilization of nitrogen in the later stage of rice, accelerates the accumulation of nitrogen transport, and promotes early maturity of rice. Especially in the newly changed paddy fields and acidic soils, the effect is more obvious. When applying the base fertilizer, the calcium and magnesium-containing silicate can be used as a silicon fertilizer to be mixed with other fertilizers.
Potatoes, soybeans, peanuts, rapeseed, etc. are “sweetened†crops. The use of “calcium†(calcium, magnesium and phosphate) is better than “heavy calcium†(heavy calcium perphosphate) because “calcium†contains calcium sulfate. "Heavy calcium" does not contain calcium sulfate. “Heavy calcium†is used for the sulfur-free crops to achieve the effect of sulfur application.
Ammonium chloride contains up to 61% chlorine and cannot be used on “chlorine-free†crops (such as tobacco, potato, sugar cane, sugar beet, melon, tea, citrus, grapes, etc.), but chlorine can increase the toughness of the fiber. Pulling force, suitable for cotton, hemp and other crops.
"Three elements" (nitrogen, phosphorus, potassium)
