Abstract

The invention relates to the field of special fertilizers for barbadosnut. The special fertilizer for barbadosnut comprises the following components in parts by weight: 20-30 parts of urea, 20-30 parts of calcium superphosphate, 6-10 parts of potassium sulphate, 10-15 parts of sulphur and 30-35 parts of borax. The special fertilizer for barbadosnut is applied in the growing period of a barbadosnut plant. In the first year of the growing period of the barbadosnut, 160-200g of the special fertilizer for the barbadosnut is applied in a position 25-35cm away from the barbadosnut plant; in the second year of the growing period of the barbadosnut, 350-400g of the special fertilizer for the barbadosnut is applied in a position 45-55cm away from the barbadosnut plant; and in the third year or later of the growing period of the barbadosnut, 550-630g of the special fertilizer for the barbadosnut is applied in a position 45-55cm away from the barbadosnut plant. The invention provides the special fertilizer which promotes the increase of increment, fruit yield and economical benefit of the barbadosnut, and provides an applying method for the special fertilizer.
