Formulated Fertilization Apply nitrogen, phosphorus, potassium and trace elements together, called formula fertilization. According to the test, the utilization rate of nitrogen is 30%~38% for single application of urea, and the utilization rate of nitrogen can be increased to 58%~60% by formula application; the utilization rate of single application of phosphate fertilizer and phosphorus pentoxide is 12%~ 14%, the application of formula, the utilization rate increased to 35% ~ 38%; the utilization rate of single potassium chloride is only 31% ~ 35%, the application of formula, the utilization rate can be increased to 57% ~ 61%.
Deep application of nitrogen fertilizer with deep application of nitrogen fertilizer can effectively prevent nutrient loss and increase nitrogen utilization rate. According to the test: the ammonium bicarbonate is applied, the nitrogen utilization rate is 28.6%, and the deep application, the nitrogen utilization rate can be increased to 58.6%; the urea application, the nitrogen utilization rate is 42%, deep application, nitrogen utilization The rate can be increased to over 80%.
Centralized application The limited fertilizer is preferentially applied to low- and medium-yield fields. According to the test: the same amount of 5 kg of urea and potassium chloride are applied to the fields of high-yield, middle-yield and low-yield fields at the same time. The yield increase effect is very different. On average, 1 kg of urea is applied, and high-yield fields increase the yield of rice. 3.5 kilograms, the middle-yield field increased rice yield by 5.8 kilograms, and the low-yield field increased rice yield by 8.8 kilograms.
A dielectric mirror, also known as a Bragg mirror, is a type of mirror composed of multiple thin layers of dielectric material, typically deposited on a substrate of glass or some other optical material.Their coating is more durable making them easier to clean and more resistant to laser damage.Broad Band supplying from 350~400 nm, 400-750nm, 750-1100nm, 1280-1600nm
We offer dielectric laser mirrors for fixed, narrowband or broadband wavelength applications covering wavelength ranges from UV to IR.
Changchun Ruiqi has a wide selection of spherical concave mirrors with metallic or dielectric coatings that together span the 250 nm - 1000nm spectral range, with focal lengths from 9.5 mm to 500 mm.
