With the use of timing with the use of The production of potassium permanganate solution is best to use cold boiled water, because its chemical properties are unstable, high water temperature will make it quickly decompose failure. The prepared aqueous solution usually can only be stored for about 2 hours. When the solution turns brown purple, it will lose the disinfection effect. Therefore, it is best to use it when it is ready for use. When it is used, it should be backlit. It should be performed outdoors before 9:00 AM or in the evening. The cloudy day must be changed at noon. The dosage is suitable for safe use The use of concentration is not only related to fish species, size, physical condition, severity of illness, bath density and other factors, but also closely related to the environmental conditions of the water, such as potassium permanganate to increase the amount of organic matter in the water when it is high . Under seawater conditions, the potassium permanganate has a stronger redox ability, so it can be used to reduce the concentration in seawater. The amount of drug should not exceed the safe concentration range, and can not be used for a long time to prevent damage to the tissues of aquatic animals and acute poisoning. The bath concentration is usually 10 mg/L to 20 mg/L for 15 minutes to 30 minutes, and the total splash concentration is 4 mg/L to 7 mg/L. Rational mix of drugs and efficient use In order to enhance the bactericidal effect, potassium permanganate can be mixed with other drugs, such as fumigation with formaldehyde, and potassium permanganate can also be mixed into a 1.1% hydrochloric acid solution. Drugs must be dissolved or diluted before they can be mixed. But with the attention to physical or chemical compatibility taboo, potassium permanganate and organic substances such as glycerin, alcohol, tannic acid, etc. will be reduced, decolorization failure, and ammonia and its preparation was floccular precipitation failure, and glycerin, medicinal charcoal The tannins can explode when ground. 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.
Potassium permanganate, due to its strong oxidizing ability, can prompt the bacteria or other organics to immediately release new ecological oxygen. It can kill bacteria by oxidizing the active genes in the bacteria, killing protozoa, monoprotozoa, and anchors. Parasites have significant effects and are traditional disinfectants with low toxicity, small side effects, and small amounts. When using potassium permanganate, pay attention to:
