PVC High Speed Door are designed for indoor use and ensure rapid handling operations between different areas that should remain separated. These safe and efficient industrial doors are made of a shaped steel frame and covered with PVC. These high speed doors are safe and efficient and consist of a shaped steel frame covered with PVC. Safety is ensured by their photocells and barriers.
High speed doors protect us from harm, save energy and help us to separate processes for optimal productivity. A high speed door's most important job is to simply open and close quickly and safely every time you need it.
The high speed pvc roll shutter door require high strains, caused by the high operating speed and the frequency of openings, have to be taken into account during construction. In the same way, basic conditions like size and installation location add up to considerable requirements regarding safety and control technique.

Ammonium molybdate is a commonly used molybdenum fertilizer, which is generally used as a seed fertilizer, and can also be used as a foliar spray fertilizer. For seeding, use 2 g of ammonium molybdate per kg of beans, first dissolve it in 5 times of hot water, stir well, and mix with water after cooling. For foliar spray application, spray 0.05% to 0.1% ammonium molybdate solution at the initial flowering stage, generally 30 to 50 kg per mu.
Molybdenum is not easily leached and lost in the soil. In the soil where molybdenum is excessively applied or molybdenum is often applied, molybdenum accumulation is likely to occur, and a long time will cause molybdenum poisoning in soybean plants. Therefore, the application of molybdenum should not be excessive, and it should not be applied in the same field for years.
Why do soybeans apply molybdenum fertilizer?
Molybdenum is a trace element, and soybeans require 100 times more molybdenum than other crops. Molybdenum can promote the formation and growth of soybean nodules, increase the number of nodules, increase the volume of nodules, and improve nitrogen fixation capacity, which in turn increases the chlorophyll content and photosynthetic capacity of soybean leaves. Molybdenum also promotes the growth of soybean roots and enhances its ability to absorb nutrients and drought resistance. Therefore, molybdenum has obvious promoting effects on soybean growth and development, pod growth and grain weight increase.
