Research and Introduction:
According to research, many people who eat an apple a day have a small chance of getting sick, and their physical condition is better, but there are many types of apples, and the varieties of apples that everyone likes to eat are different, just like some people prefer to eat black diamond apples. Because its taste tastes sweet and meets the taste of most people.
Black diamond apple:
Black diamond apple, listen to the name to know that it is very extraordinary, and our ordinary apple is certainly different, can be said to be the top existence of apples, but it is also a variety of flower cow apple, after its fruit is ripe, its skin will turn dark purple, can also be said to be black, not that it is missing any elements to cause this color.
It grows on a plateau with an average altitude of more than 3,000 meters, and because it has been exposed to sunlight for many years, its skin is deep purple-red, and it has its own natural fruit wax, which has a strong fresh texture. The temperature difference between day and night is very large, and the ultraviolet rays are also very strong, which creates its unique appearance and sweet taste.
When it is plucked from the tree in the orchard, it is still a dusty pearl. When you wipe the fruit powder on its surface, you will reveal a deep purple-black coat, which is too special and looks very eye-catching, flashing like a black diamond, showing a different high-grade texture, making people unable to take their eyes off.
Nutrients amount:
Black diamond apples are very high in nutrients, and it is also a high-end fruit in fruit stores. After all, it is nutritious and the taste is good. Black diamond apples are relatively suitable for the elderly at home, because most of the elderly people do not digest well, and it just has the effect of promoting digestion.
Black diamond apple its adaptability is also very good, whether it is high altitude or China's plain area, it can adapt well. And its disease resistance is much stronger than that of other varieties of apples, planting black diamond apples, under normal circumstances, three to five years can hang fruit. Its cold resistance effect is particularly strong, and in the weather of about minus ten degrees, black diamond apples can still grow normally.
Fertilization:
During planting, be sure to remember to fertilize it. You can choose organic fertilizer, and after it grows fruit, you must add fertilizer to supplement nutrients, so that the fruit tree can grow healthier and the taste of the fruit will be better.
Every year, loose land is given around the fruit trees. Because loose soil allows the roots of fruit trees to absorb more nutrients, speeding up its growth.
The nutrients contained in black diamonds are far beyond the reach of other fruits, for example, the VC contained in its body is many times higher than that of ordinary apples, and the peel is rich in anthocyanins. Among health fruits, it is one of the few fruits that can be consumed. Its price is much more expensive than ordinary apples, can exceed ten times, and won the first prize in China's competition to select new varieties.
Nutritious food for health:
If there is an open space at home, plant a few trees quickly, so that you can eat such delicious and nutritious food, because its yield is particularly high, and the whole family will have endless fruits to eat. You can give it to friends and family, and this all-natural fruit is very handy, or you can sell it in the market, and you can also get a good income.

Storage temperature:
The best storage temperature for apples is 0-2 °C, requiring humidity between 80%-95%, mechanical storage can perfectly solve this environmental condition, can extend the storage time of apples to 6 months, but the power consumption will be relatively large.
Another side while storage:
In addition to the apple itself slowly aging and decaying, the timing of picking will also have a great impact on apple storage. Picked too early, the apples are sour and small, and during storage, they are prone to diseases such as tiger skin, bitter bean disease and water loss and atrophy; However, if it is picked too late, the apple enters the respiratory transition period, and it will be easy to rot and deteriorate. In addition, avoid rubbing during the picking process to avoid being rained.
At the same time, apples are also respiratory leap fruits, and there is a period of sudden increase in respiration rate between the cessation of growth and the beginning of aging. At this time, apples will begin to synthesize ethylene in large quantities, which will accelerate the respiration rate of apples, promote the synthesis of proteases and amylase, and allow apples to mature and age rapidly. Ethylene will also further damage the cell structure of apples, causing fruit rot, so inhibiting respiratory metabolism and removing ethylene is a key factor in extending the storage time of apples.
All in all, apples are delicious, but also delicate, the English "palm pearl" is the apple of one's eye, fruit farmers like pearls pamper!
So, what kind of preservation process do apples go through after careful picking?
Chemical Storage /The "chemistry" here is not the use of chemicals on apples. Previously, fruit farmers did use carbendazim and methyltobutazine and other chemical preservation to disinfect and sterilize apples and extend the shelf life of apples, but these preservatives will penetrate into the pulp of apples and cause residues, so fruit farmers have gradually adopted a new "chemical" preservation technology - film preservation.
To put it bluntly, it is to wear a layer of clothing for apples, of course, the apple itself also has a fruit wax body, fruit farmers will apply a layer of chitosan to apples on the basis of fruit wax, which can effectively reduce the respiration of apples and the production of ethylene gas, and also prevent the reproduction of microorganisms on the surface of apples.
There is a modified atmosphere warehouse specially built for storing apples, and the gas composition, temperature and humidity in the storage are precisely regulated through automatic gas analysis and control equipment to ensure a low oxygen and low carbon dioxide environment. General oxygen accounts for 3%-4%, carbon dioxide is 1.5%-2.8%, and apples in the modified atmosphere library can be stored for 10 months or more.
