There are many types of fertilizers, and their effects vary. Some fertilizers can improve the quality and yield of vegetables, while some will affect the quality and yield of vegetables. Some fertilizers can increase the yield of vegetables, but they will produce toxin pollution in vegetables, causing consumers. Poisoned.
1. Ammonium nitrate and other nitrate nitrogen fertilizers are generally not suitable for application to vegetable nitrate nitrogen fertilizer. When applied to vegetable fields, the nitrate content in vegetables is doubled. Nitrate is easily reduced to nitrite and nitrous acid in human body. Salt is a carcinogen and is extremely harmful to humans.
2, ammonium chloride, potassium chloride and other chlorinated fertilizers, should not be applied to tomato, potato, sweet potato and other chlorine-containing fertilizers in the soil decomposition, ammonium or potassium ions will be absorbed by the soil and absorbed by vegetables, when the concentration reaches a certain level It will poison the roots of vegetables and cause serious death of vegetables.
3. Nitrogen fertilizer should not be used for foliar application of leafy vegetables. Spraying nitrogen fertilizer on the foliage of vegetables, the ammonium ions are easily converted into acid ions and absorbed by the leaves after contact with air. Leafy vegetables have a short growth period and it is easy to accumulate nitrate in the leaves.
4, the application of micro-element fertilizers in vegetables can promote high-quality and high-yield vegetables, but vegetables require very little trace elements. Excessive application of trace element fertilizers not only causes waste, but also poisons vegetables and pollutes the environment. For example, the amount of ferrous sulfate should not exceed 3.25 kg, the amount of manganese sulfate and manganese chloride should not exceed 2.05 kg, the amount of copper sulfate should not exceed 2 kg, and the amount of borax and boric acid should not exceed 1.25 kg.

Magnetic Track
LED magnetic rail is an innovative lighting system that combines LED lighting technology and magnetic technology. It uses magnetic suspension to fix the LED luminaire on the track to achieve convenient installation and positioning.
LED Magnetic Track Lighting has unique advantages. First of all, as a light source, LED has the characteristics of high brightness, low energy consumption, and long life, which can provide energy-saving and environmentally friendly lighting effects. Secondly, the magnetic technology makes the installation and disassembly of the lamp very simple, just align the lamp with the magnetic channel, and it can automatically adsorb and maintain a stable position. This design facilitates the replacement and adjustment of lamps without the use of tools or cumbersome fixing operations.
The LED magnetic track system is suitable for the lighting needs of various places, such as commercial Spaces, home lighting, and office environments. It can be used to illuminate an entire space or highlight specific areas, providing comfortable and even light. Due to the flexibility of the magnetic wiring, the lamps can move and rotate freely along the track to adapt to different lighting angles and needs. In addition, the LED magnetic track also supports dimming and color temperature adjustment functions, and users can adjust the brightness and color of the light according to their needs, creating an ideal lighting atmosphere.Magnetic Rail,Magnetic Track Rail,Magnetic Track System,Magnetic Channel,Magnetic Wiring
