Ten defenses in the process of chemical fertilizer storage and transportation

One is to prevent stacking in the open air. Can not open dumps fertilizers, such as ammonium bicarbonate is placed at open air temperature of 20 ℃, ammonia loss rate is 8.8% one day, 5 days 48% 10 days 74% loss. Therefore, the fertilizer should be placed in a cool and dry place inside the house.

 

Second, prevent moisture. After the water is wet, the "water" is lost, and the superphosphate will form a hard block and become insoluble. Therefore, the application of chemical fertilizers or linoleum is strict, and it is best to leave the wet source without overhead.

 

Three defenses are heated. The higher the temperature, the more the deliquescent volatilization and agglomeration of the fertilizer (the worse the stability ) , so it is necessary to adjust the temperature of the storage house in time to keep it below 30 °C. When the temperature outside the room is low, the door and window should be opened to lower the room temperature. Good not to be in the kitchen with heat.

 

Four anti-volatile. The ammonium carbonate has poor stability and is easily decomposed and volatilized. When the temperature is higher than 20 °C, it will be decomposed into ammonia gas, carbon dioxide and water to cause loss. Therefore, check if the package is damaged, handle it lightly, and use as much as you can.

 

Five to prevent fire. Ammonium nitrate, potassium nitrate, etc. are flammable. They should not be stacked together with flammable materials such as kerosene, gasoline, straw, wood chips, etc. during storage to avoid fire.

 

Six anti-explosion. Ammonium nitrate, potassium nitrate, etc. are easily exploded. If they are mixed with metal powders such as copper and iron, they may cause an explosion if they are rubbed. Therefore, after these chemical fertilizers are hardened, do not use metal objects to slam them. Use heavy objects to crush them.

 

Seven anti-corrosion. The superphosphate contains free acid, which has corrosive effect on storage utensils and human skin. It should not be directly contacted during storage, or placed in a metal container, or placed together with crop seeds and clothing, so as not to affect the germination rate. And corrosive items.

 

Eight anti-mixing. Fertilizers are acidic and alkaline, and should be classified and stored separately according to the place of origin, type and nature, so as not to reduce the fertilizer efficiency.

 

Nine anti-poisoning. When carrying poisonous and corrosive chemical fertilizers, such as ammonium bicarbonate has a pungent odor, it will volatilize a toxic crop - cyanamide fertilizer, it is best to wear a mask, gloves, goggles to prevent poisoning, and should wash the exposed skin after handling .

 

Ten anti-ingestion. Fertilizers should not be mixed with pesticides, human and animal drugs, or food items ( such as sugar, salt, etc. ) to avoid misuse. In particular, children should be prevented from eating and eating in storage places to avoid undue accidents.
