Kumquat is very sweet and has no normal moisture. According to relevant information, kumquat is very sweet, and water shortage is caused by water shortage of fruit trees. The leafy branches have strong ability to absorb nutrients and are prone to overnutrition (too much nitrogen). Excessive potassium causes nutritional imbalance and hinders the absorption of magnesium, calcium, manganese and zinc. Kumquat is mainly produced in China, Hainan and Viet Nam. However, due to climate and variety problems, Vietnamese fruits are not as good as Hainan kumquat in taste and quality. Hainan kumquat is an evergreen shrub with dense branches and leaves, beautiful and elegant crown branches, white and bright flowers and petite fragrance. Kumquat is characterized by eating the peel and pulp together. After chewing, I feel my throat moist and fragrant.
