Storage of fertilizers in the cold season should be "four defenses"

Some people think that in winter, the temperature is low, chemical fertilizers do not evaporate, and they are not corrosive. This is not the case.

Ammonium bicarbonate, ammonium sulfate and other nitrogen fertilizers are not non-volatile at low temperatures, but are slower in rate of volatilization and less volatile than summer and autumn high temperature seasons; the corrosiveness of superphosphate is not much related to the temperature, bag, As long as the sack is exposed to SSP, it will be corroded and the contents of the bag such as seeds, salt, soda, etc. will deteriorate. In addition, the nitrogen vapor after the evaporation of vapor encountered in the air, will be converted into a strong corrosive ammonium hydroxide, will cause seed embryos lose the germination force, so that food deterioration, pesticides failure.

In view of the above reasons, the “four preventions” are also required to store chemical fertilizers in the cold season.

Anti-volatilization of many nitrogen fertilizers, such as ammonium sulfate, ammonium bicarbonate, ammonium nitrate, etc., due to the extremely unstable nature, easily decompose and volatilize during storage, reducing fertilizer efficiency. Therefore, such fertilizers should be stored in airtight plastic bags or other sealed and corrosion-resistant containers.

Waterproof and moisture-proof nitrogen fertilizer is easy to agglomerate or lose water after being exposed to moisture or water, and it must be kept dry during storage and storage to prevent breakage of bags.

Anti-pollution ammonia fertilizer, etc. can not be placed in the bedroom, hall, so as to avoid volatile ammonia gas stimulate people's eyes, nose and respiratory tract, endangering health.

Anti-corrosion ammonium bicarbonate, superphosphate, etc. cannot be stored in sacks, sacks, and paper bags and should be stored in plastic bags or porcelain jars. All kinds of chemical fertilizers cannot be stored in a house with seeds, grain, oil, farm implements, etc.

Foot of ningxia hong xingda incense Organic Apple fruit suborbicular, fruit surface color yellow green, most with orange chardonnay fruit surface, covered with bright red stripes, pulp yellow-white, succulent crisp, sweet, rich fragrance, quality first-class; The fruit has a sugar content of over 15%, more than 4% of the national average, and the flesh is tight and crisp and sweet, which is widely loved by consumers all over the world. There is a longer optimal consumption date than any other apple, not even refrigerated. It can be kept for 4 months at normal temperature. If refrigerated, Fuji can be kept for 5--7 months.
Altitude: high altitude area light, clean air, environment close to original condition, no industrial pollution. With an average elevation of 1160-2900m, the central health center has a strong uv light, which produces the natural pollution-free apple, which conforms to the concept of a modern green diet.
Temperature: moderate temperature can avoid the chance of fruit tree encountering disease. The average temperature in ningxia is 8.4 degrees Celsius, which has an important influence on the growth, development, yield and quality of apple. The piedmont apple is thriving in such a good environment.
Humidity environment: moderate amount of rainfall provides necessary conditions for apple's growth. The annual rainfall in the central health region is 186 millimeters. The fruit is slow to grow and the fruit is hard and hard, which fully guarantees the fruit's sugar content and the relatively average size of apples.
Sunshine condition: apple is the fruit tree, the central health area of the whole year is nearly 3,800 hours, is beneficial to the Apple Fruit coloring. The piedmont apples are red and bright.
Temperature difference factors: ambassador apple nighttime respiration weak temperature gap between day and night, consume less organic matter, the accumulation of organic matter during the day more, that apple store down a large number of glucose sugar candy, etc have better taste. The average diurnal temperature difference between apple and apple is 14 degrees centigrade, and the larger diurnal temperature difference ensures the sweet and delicious characteristics of the apple.
Other factors: frost can make apple blossom and fruit, which can cause frozen flower jelly, which is bad for apple's production. The piedmont apple has been kept at least 167 days without frost for the whole year, which minimizes the influence of apple on yield and quality.
