Which fertilizers should not be applied to vegetables?

Some fertilizers can improve their quality and yield after being applied to vegetables. However, although some fertilizers can increase the yield after being applied to vegetables, they will cause pollution to vegetables and cause poisoning to consumers.
Ammonium nitrate and other nitrate nitrogen fertilizers are generally not suitable for application to vegetables. When the nitrate nitrogen fertilizer is applied to the vegetable field, the nitrate content in the vegetable is doubled. The nitrate is easily reduced to nitrite in the human body. The nitrite is a highly toxic substance and is extremely harmful to the human body.

Centrifugal Glass Wool Pipe

Yu Ou Nuo centrifugal glass wool pipe shell are specially used for the thermal insulation of various pipes (including: freezing, hot water, steam) systems. They can work normally at an ambient temperature of -4℃-454℃, and can be exposed or concealed.

Because the pipe covering of this material has the characteristics of waterproof, anti-corrosion, mold-free, and insect-free, it can effectively prevent condensation and prevent pipeline freezing. It is widely used in civil buildings, heating pipelines, air conditioning, and refrigeration equipment. Thermal insulation, energy saving effect can be increased by 15-30%.
