The biological properties of molybdenum are also important, as it is an essential trace element not only for plants but also for animals. Molybdenum is one of the main components of molybdenum flavin protease in nitrogen-fixing bacteria in plants; it is also one of the main components of plant nitrate reductase; it can also stimulate the activity of phosphatase, promote the synthesis and transportation of sugar and starch in crops; it is conducive to early maturity of crops . Molybdenum is one of seven important micronutrients. Molybdenum is also one of the basic components of xanthine oxidase and aldehyde oxidase in the liver and intestine of animals, and also the basic component of heparin sulfite oxidase. Studies have shown that molybdenum has obvious anti-caries effect, and molybdenum has a strong inhibitory effect on the formation of urinary stones. A healthy person weighing 70kg contains 9mg of molybdenum in the body. For humans, molybdenum is the only element known to be essential to humans among the second and third transition elements. Compared with similar transition elements, molybdenum has extremely low toxicity and can even be considered basically non-toxic. Of course, excessive ingestion also accelerates the oxidation of the elastic substance - plasmalogen - in the walls of human arteries. Therefore, in areas with high molybdenum content in the soil, the incidence of cancer is lower, but the incidence of gout and systemic arteriosclerosis is higher. Animals, especially long-horned animals, who eat forages containing excessive molybdenum are prone to stomach problems.

In the middle route of the South-to-North Water Transfer Project, the main channel has wide channels and large slopes, and the surface quality of the concrete lining is high. It is difficult to complete by manual or simple equipment. The large-channel lining equipment is developed to adapt to long-distance and large-section channel lining construction. An advanced and efficient equipment. It integrates machine, electricity and liquid, and can spread the cement at the bottom and slope of the channel of 5~25 meters width. It is reported that this prototype has been transported to the Jinan site in Shandong for further on-the-spot assessment.
