In winter, fruit farmers are often seen to be busy in the orchard, doing work such as cutting and scraping. The reason why fruit trees are to be scraped is because old skin is an important place for pests and diseases to survive winter. There are often a large number of germs or eggs that winter in this place. These will become an important source of pests and diseases in the orchard in the coming year. Therefore, in order not to affect the quality of the fruit next year, Therefore, the farming process of scraping the skin.
Fruit tree scraping is an important measure for winter orchard management. This is not only beneficial to the enhancement of tree potential, but also can prevent premature aging of trees, and it is also crucial to eliminate wintering pests and diseases in bark cracks. The role of the "do not apply pesticides, win pesticides" prevention and control effect, to meet the requirements of the more fiery and pollution-free fruits and vegetables in recent years.
The "five unfit" criteria for winter fruit tree scraping
Fruit tree scraping is actually very simple. It is mainly to scrape the trunk and the rough skin and the skin on the main branch during the winter management process. It sounds very simple, but if you ignore the following five requirements during the operation, then the skin is scraped. The effect will be greatly discounted.
First, it should not be too early
The general experts will say that the period of fruit tree scraping is mainly from the beginning of the fruit tree to the flowering, and the sooner the better. In fact, there is a mistake in this statement. It takes about a few months to fall into the middle of flowering. If we scrape the skin too early, it will easily cause the early young tissue to be exposed, plus the weather factor. It is easy to cause the loss of water, and the ability to remove the "coat" of the fruit tree will also reduce the cold resistance. It is recommended that the scraping is better before the fruit tree is germinated.
Second, should not be too deep
People rely on one face and the tree rests on a piece of skin. If we pull someone's face completely down, who will be willing, the fruit tree is the same. When the fruit tree is scraped, the depth of the skin should not be too deep. It is better to scrape off the body and knock out the skin. This way, on the one hand, the place where the pests and diseases are overwinter can be removed, and the other side will not cause the fresh protective tissue to be exposed and endangered. The safety of the fruit tree itself.
Third, should not be too thick
In the process of scraping the skin, most fruit farmers often only operate the trunk and main branch of the tree, and often ignore the branchlets of more than one year old. This makes it easier to miss the places where the following pathogens exist, so that the pathogens can not be removed in the winter orchard. The purpose of the place.
Fourth, should not be burned
Usually, in the process of clearing the orchard in winter, in most cases, the removed diseased branches and dead leaves are taken out of the orchard or burned in a concentrated manner, which is theoretically a waste of resources. A better measure is to collect the things scraped off such as the skin, and then dig a deep pit about 30 cm or more in the orchard for burial. With the later fermentation and decay, these things become the best in the orchard. Nutrient source.
Five, not suitable "still"
Fruit farmers usually stick to the principle that which agent has been used in the past and which one has been used. However, with the development of science and technology, most of the emerging drugs are now pollution-free products, which are superior to the high-residue and highly pathogenic agents in the past. Therefore, after scraping the skin, some gum or biofilm can be used for painting and spraying. The effect of this operation is better, and it is more in line with the development requirements of contemporary agriculture.
The above is about the "five unsuitable" of winter fruit tree scraping. Winter is the best time to rest, and the orchard is the same. After a year of flowering and fruiting, the fruit tree grows out of nutrients for one year. . Therefore, we can also apply some fertilizer, which is more conducive to the growth of fruit trees, but also to ensure the yield and quality of the fruit next year.
Anthocyanidin, also known as anthocyanin, is a class of water-soluble natural pigments, flavonoid compounds, widely found in plants. It is also the main coloring substance in plant petals, and most of the colorful colors of fruits, vegetables and flowers are related to it.Anthocyanins belong to the flavonoids (flavonoids) of the phenolic compounds.
Anthocyanins provide a variety of benefits to the human body. Fundamentally, anthocyanins are a powerful anti
oxidizer, which protects the body from damage caused by a harmful substance called free radicals. Anthocyanins also enhance the elasticity of blood vessels, improve the circulatory system and smoothness of the skin, inhibit inflammation and allergies, and improve the flexibility of joints.
Also used in cosmetics, such as red anthocyanins for lipstick. These commercial pigments (in addition to grape skin pigment) is a common feature of light, heat, oxygen stability, microbial stability. Generally soluble in water and ethanol, insoluble in vegetable oil.
There are over 300 different anthocyanins in nature. They come from different fruits and vegetables such as purple sweet potatoes, lingonberries, cranberries, blueberries, black goji berries, grapes, elderberries, blackcurrants, purple carrots, and red kale, ranging in color from red to blue. These anthocyanins mainly contain Delchindin, Cyanidin, Petunidin and Peonidin. Of these, blueberries contain the largest amount of anthocyanins and have the most nutritional value.
