Why do citrus have sun nuts? What is the sun fruit in the citrus orchard?

Citrus sunfruit is also called sunburn fruit, generally the fruit with few branches and leaves or the top fruit is not easy to be blocked, the sunfruit is more likely to appear, and the fertilization management, partial nitrogen fertilizer, insufficient calcium, and fragile peel tissue are also the reasons for the appearance of sunfruit. In July and August every year, we should start to do a good job of prevention, control nitrogen fertilizer in nutritional management, supplement calcium fertilizer, spray micro covering force on the foliar surface many times, directly supplement calcium to the fruit, and also wrap a layer of calcium film on the fruit surface to effectively reduce the sun fruit.

It is a vegetable stewed swallow with sun fruit.

Ingredients: 1 sun fruit, 50 grams of high-grade official swallow, appropriate amount of honey. Production:

Pour the honey into the fruit and steam it for 15 minutes, after the official swallow flies the water, dry the water and put it into the fruit, put in coconut water, almond milk, condensed milk, rock sugar, etc. according to the taste, and stew for 10 minutes before eating. Flavor: The flesh and the swallow complement each other, which is very suitable for fashionable women.

Sun fruit pulp.

1.Steam the pork belly first (15 minutes); Then untie the knife into a square; 2.Mix the sauce and cook with the pork belly for 20 minutes, remove and set aside.

3.Cut the sunberries and steam them. Put the pork belly in the fruit.

The juice is buried and ready to eat. Features: It can lower blood lipids, suitable for all seasons, and is the most suitable in autumn.

The taste has the fragrance of osmanthus, and the pork belly meat melts in the mouth.

Citrus sunfruit generally occurs in July and September every year, due to the high temperature and strong light exceeds the carrying capacity of citrus, and once it enters the summer, the temperature can reach more than 35, and the temperature on the surface of the citrus peel even reaches more than 40-45. This leads to the destruction of the cell wall of the pericarp, causing the breakdown of chlorophyll, which can lead to the drop of the sunfruit.

It should be that some trees have mutated, and the fruit produced has become the sun fruit, so this is the case.

Citrus sunfruit is also called sunburn fruit, simply put, because of the high temperature weather, long-term exposure to the sun only, change the fruit, this often reduces our benefits, the general solution is to reduce the peel sunshine intensity to avoid direct sunlight or the idea of improving fruit thickness and stress resistance.

Many of us commonly spray sunscreen directly, but some have a certain impact on the taste and quality of the fruit, and there is a way that everyone may know, but do not pay attention, that is, to control nitrogen fertilizer, pay attention to the use of calcium and boron fertilizer, so as to improve the stress resistance of the fruit by improving the hardness, thickness and toughness of the peel tissue, in addition, the use of boron-calcium foliar fertilizer containing organic acid helps to promote the thick green growth of citrus leaves, and also helps to reduce citrus sunburn fruit through the protective effect of leaves.

Sichuan Mr. Chen planted a lot of mandarin oranges, these two years has been foliar spraying organic acid calcium boron foliar fertilizer, every year said, their citrus sun fruit is very few, much less than the surrounding people, basically the same fertilization management, just a few more times to play organic acid boron calcium foliar fertilizer is a lot better, and from the early stage of the use of citrus leaves thick green and more, which also plays a certain role in protecting the fruit, of course, comprehensive management is very important, this needs to pay attention to.

For the prevention of citrus sun fruit, calcium and boron are not good, and other measures are relatively keeping up, and the effect is still very good, especially the quality and taste of the fruit can also be supplemented and kept up, which is still good.

It is possible to bring bags for citrus when they have grown to a certain extent, which will prevent sunfruits.

1. Starting from the young citrus fruits, each spray should appropriately add calcium, potassium, magnesium and other elements, about product selection, it is recommended to choose functional products such as leaf Shuo calcium chili, potassium chili, magnesium chili.

2. Choose a suitable spraying time to avoid high-temperature spraying, especially from 11 a.m. to 3 p.m.

3. If there is high temperature and drought from July to September, irrigation should be carried out in time, combined with the high-yield and disease-resistant nutrition program of Yeshuo citrus to prevent yellow trees and yellow leaves to protect trees, and scientifically distribute fertilizer.

Summary. Sunfruit is a physiological disease caused by high temperature and long-term direct sunlight, and it is most likely to occur during the fruit expansion period from July to September every year. At the beginning of sunburn, the surface of the peel will turn yellow with small gray-brown spots; In the later stage, the burned area will become a dry scar, become hard and rough, and the fruit will also lose water and lose its commercial value, so it can only be removed.

Citrus sunburn, once formed, cannot be restored and therefore can only be prevented.

Sun fruit is a physiological disease caused by high temperature and long-term direct sunlight, and it is most likely to occur during the fruit expansion period from July to September every year. At the beginning of sunburn, the surface of the peel will be yellowed and dismantled, and small gray-brown spots will appear. In the later stage, the burned area will become a dry scar, become hard and rough, and the fruit will also lose water and lose its commercial value, so it can only be removed. Once citrus sunburn is formed, it cannot be recovered, so it can only be pre-traveled.

Is it that citrus varieties of fruit trees will have fewer sunberries than orange varieties.

The main thing has a lot to do with the weather.

High temperature and little rain are easy to bleed.

How to prevent it. 1. Pay attention to pruning, cultivate a three-dimensional staggered tree and roll slag-shaped crown, so that the middle and lower parts and the inner hall can hang more fruits, and at the same time, at the end of June, put some late acres of quiet summer tips to shade the sun, so as to reduce the late sun exposure.

2. For Maogu mandarin, mandarin orange and other easy-to-scorch jujubes, the fruit surface is whitened or labeled in advance for protection. Painted white, with light calcium carbonate (putty powder) and glue smearing, the ratio of powder and glue is generally 1:2 or; Stickers, which can be done with the help of double-sided tape.

3. To cultivate a stable tree potential, fertilizer and water should be sufficient, especially calcium, magnesium, potassium, silicon, boron, old zinc and other elements can not be missing, so as to enhance the resistance of the tree, the thickness and toughness of the fruit family's bright bark.

The use of citrus film, citrus special sunscreen whitening agent, can effectively prevent sun fruit.

The fish citrus film is a colloidal calcium fertilizer, which has been fully verified by the actual use of Maogu mandarin and mandarin orange in Guangxi, Guangdong, Yunnan and other places. The plant sunshade will form a delicate and viscous protective film on the surface of the fruit, which can reflect ultraviolet rays for a long time, protect the fruit surface, and can physically prevent red spiders and embroidery ticks. This product is safe, environmentally friendly and residue-free for citrus.

You can use a fish orange film to protect against the sun and apply it white.

"Fish citrus film" colloidal calcium fertilizer, barrel, total calcium content of 20%, is the fifth generation of plant sunshade, through Guangxi, Guangdong, Yunnan and other places Maogu orange, mandarin orange practical use, anti-sunburn effect has been fully verified. The plant sunshade will form a delicate and viscous protective film on the surface of the fruit, which can reflect ultraviolet rays for a long time, protect the fruit surface, and can physically prevent red spiders and embroidery ticks.

Reasonable pruning, retain a certain number of branches and leaves, reduce fruit damage caused by direct sunlight, comb the fruit to stay low but not high, ensure that the land is moist in the high temperature stage, and sufficient moisture will reduce the occurrence of scorched fruit.
