The invention provides a planting method of
selenium-rich
sugar oranges. The planting method comprises the specific steps of 1, choosing seeds and conducting pretreatment; 2,

selenium-rich
sugar oranges, the
sugar oranges cultivated through control over conditions of seed choosing,
sowing and
seedling growing, planting field treatment, the arrangement of field planting and choices of water, temperature and illumination in the field management are uniform in fruit bearing, the fruit shape size and the mature degree are identical, the fruit is big in size and sweet in pulp, the
mouthfeel is good, the diseases of fruit russeting,
cracking fruits, malformed fruits and the like and various spotted
disease phenomena caused by fungi are effectively prevented, and
disease-resistant, drought-resistant and chilling-damage-resistant abilities are remarkably improved; in addition, according to the planting method, by adding the
selenium-containing
fertilizer in the planting field treatment and applying the organic selenium solution in the flowering stage, the combination of the selenium-containing
fertilizer and the organic selenium solution makes the produced sugar oranges high in selenium content, and make ordinary sugar oranges become extremely characteristic functional fruits.
