Tungsten Oxide

Nitrate nitrogen refers to the nitrate fertilizer contained in nitrate, which is mainly used in fruit trees. It can stop the development and deformity of fruit. It is one of the main fertilizers for crop growth and prolonging crop growth and harvesting period,it plays a crucial role in the growth of crops. However, the use of nitrate nitrogen is a double-edged sword, on the one hand, nitrogen fertilizer can improve the yield of crops, on the other hand, the excessive use of nitrogen fertilizer will also pollute the rivers and lakes, soil and underground water, resulting in major rivers appear eutrophication, algal growth, leading to ecological extinction. How can you find a balance between efficiency and the environment? Scientists have been trying to find the answer. Some scholars think of sodium tungstate . Sodium tungstate has been widely used because of its low toxicity, no harm to environment, human body and crops, and no breeding of microorganisms. Some scholars have add...
