Occurrence characteristics of citrus floating fruit

There are many factors that cause citrus puffiness to occur. Such factors as weather, nutrient conditions, tree vigor, and storage will affect it.

● Related to the breed

Floluta fruit mainly occurs in the late stage of fruit ripening, and peeled broad-leaved citrus fruits such as Satsuma mandarin oranges, Amaranthus persicae (5), Echinococcus mutans disease, 20 milk extracts (D) frames, and 20 Chasing (5)? ​​MǔT Discarding female students? Immortals? Small (9) Parents?

● related to fruit size

The degree of occurrence of floating fruit is closely related to the size of its fruit. The bigger the fruit, the more severe the floating skin.

● Related to the situation of the tree

Strong fruits and young trees produce fruit with less fruit. Fruits with younger trees produce fruit. Fruits at the top of the crown, ascending fruit, and rough shank, have better nutrient conditions and become more coarse and large. Floats appear.

● related to fertilization

The application of strong fruit fertilizer is too late. Excessive nitrogen in the fruit tree not only affects the coloration and maturation of the fruit, but also promotes the secondary hypertrophy of the fruit, which contributes to the occurrence of floating skin.

● related to weather factors

Citrus strong fruit season drought, or fruit coloring period of rainfall, high temperature, high humidity, are prone to skin floating. While there is less rainfall during the mature period and the climate is drier, there is less floating fruit.

● related to nutrition

Calcium is the most important factor determining the hardness of fruit. Insufficient calcium in fruit enlargement period, loose connection between peel cells, poor toughness, it is easy to produce floating skin. The lack of boron in citrus causes calcium deficiency, which in turn promotes the occurrence of floating fruit. Citrus peel uneven, mostly caused by calcium deficiency, lack of boron.

● related to the use of growth regulators

If gibberellin is sprayed too early, the concentration is too large, or foliar fertilizers containing hormones are sprayed during fruit protection, the development of the mesocarp will be partially impaired, and floating fruit will appear during the ripening period of citrus.

● related to harvest time

Delayed harvest, skin aging, prone to skin. The later the harvest period, the more severe the floating skin.
