There are many ways to reduce the nitrogen fertilizer, but except for the volatilization loss of nitrogen, it is produced by nitrification. Therefore, the improvement of nitrogen fertilizer utilization rate is mainly to prevent ammonium nitrification. 1. Deep fertilization. The ammonium nitrogen fertilizer or urea is deeply applied to the reducing layer of 3-5 cm depth, and the ammonium ion is adsorbed by the soil colloid, and is kept in the reducing layer to prevent the fertilizer from being nitrified in the oxide layer to improve the utilization rate of nitrogen. Deep fertilization can be divided into deep application of ball fertilizer, deep application of deep layer and deep application of liquid fertilizer. 2. Nitrogen fertilizer synergist. Also known as nitrification inhibitors, the use of chemical agents to inhibit the denitrification of soil microbes in rice fields to reduce the loss of nitrogen. At present, China's main nitrogen fertilizer synergists include cetyl and pyridine. This article URL: How to improve the utilization rate of nitrogen fertilizer in paddy fields Our pp foil combined cap is widely used in the hospital and clinical infusion issue.The main working procedures such as injection molding, assembly, inspection, inner packing and outer packing will go under a series of regular management system. During the whole procedures,firstly, we use the injection molding machinery to form a cap with a hole in its head,then we will embed a gasket into the hole and then use a pressing slice to fix the cap and the gasket, at last, we will seal the combined cap with a suitable film on it. We will check the sealing ability to prevent the leakage in application before we ship the cargo. If you are interested in our this type product, your detailed inquiries will be great.
