Fertilizer storage to achieve "six defenses"
In high temperature and rainy season, chemical fertilizers should be mainly stored in warehouses. The Kunei should be ventilated, cooled, and protected from rain and moisture. Fertilizers are stored in warehouses in both bulk storage and bag storage.
For nitrogen fertilizers with strong hygroscopicity, such as ammonium, no matter whether they are stored in large piles or stored in bags, in order to avoid agglomeration, the heights of bulk piles and stacks should be controlled, such as large bags of 25 to 40 kilograms, with 20 bags. Heap is moderately high.
If you choose to store the shed, the place to be stacked should be in a place with high ground, flat ground, and no water, bunk beds or plastic film. After the fertilizers are stacked neatly, the plastic film is used to cover them, and at the same time, roofs are erected, covered with tarpaulins and other measures to prevent rain.
Here, we must especially remind that the "six defenses" should be implemented for the storage of chemical fertilizers.
A volatile ammonia, ammonium bicarbonate is very volatile, so be sealed when stored. Nitrogen fertilizers and superphosphate are also prohibited from being mixed with alkaline substances such as lime and grass ash to prevent chemical reactions, causing nitrogenous chemical fertilizers to evaporate and reduce the fertilizer efficiency of phosphate fertilizers.
The two moisture-proof ammonium, lime nitrogen and calcium superphosphate are easy to agglomerate after moisture absorption, which affects the application effect. After ammonium bicarbonate absorbs moisture, the nitrogen is volatile, and it must be tightly sealed to avoid contact with air. Therefore, these fertilizers should be stored in a dry, cool place.
The three anti-corrosion calcium superphosphate is corrosive and should be prevented from contacting the skin and metal utensils. The ammonia water is strongly corrosive to copper and iron and should be stored in ceramics, plastics, and wooden containers. In addition, chemical fertilizers should not be piled up with seeds, and do not use chemical fertilizers in bags to avoid affecting seed germination.
Four high-temperature nitrogen fertilizers exposed to the sun, nitrogen will accelerate the loss of volatilization; ammonium will break down oxygen in the event of high temperatures, which will cause fertilizer failure.
5. The fire retardant ammonium, potassium, etc. are flammable and must not be stored together with flammable materials such as kerosene, gasoline, straw, wood chips, etc. to avoid fire.
Six anti-metal ammonium, potassium and other metal powders mixed with copper, iron, etc., once the friction impact, it will cause an accident. Therefore, after the hardening of these fertilizers, do not use metal objects and smash them with heavy objects.

Apple are native to central and southeastern europe, central and western asia, and xinjiang in china.later, the romans began cultivation and grafting.in the 18th century, j.b. Montessori and t.a. Used natural hybridization to select and breed seedlings and gradually promoted cultivation.
Apples are native to central and southeastern Europe, Central and western Asia, and Xinjiang in China.In Europe, m. P.Cato recorded varieties of apple in 300 BC.Later, the Romans began cultivation and grafting.In the 18th century, J.B. Montessori and T.A. used natural hybridization to select and breed seedlings and gradually promoted cultivation.After the discovery of the New World, European immigrants brought apples to America, where many new varieties were bred.Japan introduced apples from Europe and America during the Meiji Restoration.Since then, Oceania, Africa have also been introduced into the apple.Over the past hundred years, the world's five continents have apple cultivation.The earliest Europeans had eaten, improved and bred apples, some of which were seen more than 2,000 years ago, and hundreds of varieties were known in Europe before the colonization of the Americas.With the wave of immigrants to North America, seedling apple varieties spread everywhere, becoming itinerant ambassadors for local legends who played a major role in the spread of the apple
