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 added a small amount of tungstate to the nitrate nitrogen in citrus cultivation, but a small change has resulted in unexpected returns.
Studies have shown that in citrus cultivation, the addition of a small amount of tungstate can promote the plant to better absorb nitrate nitrogen fertilizer useful elements, this is because the nitrate reductase (NR) is the key enzyme in the process of nitrate nitrogen action and rate limiting enzyme, this is because the nitrate reductase (NR) is a key enzyme in the process of nitrate nitrogen action and rate limiting enzyme, its activity reflects the ability of plants to restore and transform nitrate nitrogen, and is closely related to the ability of plants to absorb and accumulate nitrate nitrogen, the enzyme is a water-soluble molybdenum protein, with the same poly-subunit protein.
Each subunit contains three auxiliary: Flavin adenine dinucleotide (FAD), cytochrome (Cytc), and molybdenum cofactor (MoCo), each auxiliary group is a redox process in which molybdenum atoms (Mo) act as an important component of the enzyme and participate in the reduction of nitrate nitrogen to ammonium. The properties of tungsten atom (W) in sodium tungstate (Na2WO4) are similar to that of molybdenum atoms, which can directly replace molybdenum in the nitrate reductase complex, in short, sodium tungstate can play a role in inhibiting reductase activity, so that the plant water to absorb nutrients, and the nutrients just right to pass on the fruit, rather than overeating caused by loss of nitrogen fertilizer to the soil, this is also the secret of citrus fruit being more sweet and full catalyzed by sodium tungstate.
To sum up, adding appropriate amount of sodium tungstate can promote the better absorption of nitrogen fertilizer plants, so as to enhance the efficiency of nitrate use, while improving crop quality while reducing the amount of nitrogen fertilizer, in order to achieve efficiency and environmental balance.
