In the autumn, fruit growers use a lot of fertilizer. During the storage and transportation of fertilizers, the following ten points need to be guarded against: One is to prevent open storage. Fertilizers cannot be piled up in the open air. For example, when ammonium bicarbonate is placed outdoors at an air temperature of 20°C, the ammonia loss rate is 8.8% for 1 day, 48% for 5 days, and 74% for 10 days. Therefore, the fertilizer should be placed in a cool and dry place in the house. Second, prevent moisture. Nitrate and ammonia will lose water after “drainingâ€, and the superphosphate will form a hard block and become insoluble. Therefore, chemical fertilizers are tightly packed with plastic or linoleum, and it is better to avoid contact with wet sources. Three against heat. The higher the temperature is, the more volatile and agglomerate the fertilizer becomes (the worse the stability is). Therefore, timely adjust the temperature of the storage house and keep it below 30°C. When the temperature outside the house is low, you should open the doors and windows to reduce the room temperature. Better not in the kitchen with heat. Four anti-volatilization. Ammonium carbonate is poor in stability and easily decomposes and evaporates. When the temperature is higher than 20°C, it will decompose into ammonia, carbon dioxide and water and cause loss. Therefore, it is necessary to check whether the package is damaged, how to use it, and how much to use. Five against fire. Ammonium nitrate, potassium nitrate, etc. are flammable and must not be stored together with flammable materials such as kerosene, gasoline, straw, wood chips, etc. to avoid fire. Six explosions. Ammonium nitrate, potassium nitrate, etc. are prone to explosion. If they are mixed with metal powders such as copper and iron, they can cause explosion accidents if they are rubbed. Therefore, after the hardening of these fertilizers, do not use metal objects and smash them with heavy objects. Seven anti-corrosion. Superphosphate contains free acid, which has a corrosive effect on storage equipment and human skin. It should not be stored in direct contact with the product or exposed in metal containers, nor should it be placed together with crop seeds and clothing so as not to affect the germination rate. And corrosive articles. Eight anti-mixing. Fertilizers are acidic and alkaline and should be classified and placed according to place of production, type, and nature so as not to reduce fertilizer efficiency. Nine anti poisoning. When handling poisonous and corrosive fertilizers, such as ammonium bicarbonate, there are obvious irritating odors that volatilize a toxic substance, cyanamide. It is best to wear a mask, gloves, goggles to prevent poisoning, and to wash exposed skin after handling. Ten prevent misuse. Fertilizer can not be mixed with pesticides, human and animal drugs, food items (such as sugar, salt), etc. to avoid misuse. In particular, children should be prevented from playing and eating in the storage area so as not to cause undue accidents. China Agricultural Network Editor
