Tsaoko amomum fruit fertilization method

The invention discloses a tsaoko amomum fruit fertilization method comprising the following steps: step I, at the end of October, fertilizing for the first time when new roots of tsaoko amomum fruit begin to develop and grow and flower buds and branch-leaf buds of the next year begin to form on basal stems, digging a semicircular shallow trench of which the width is 6-8cm and the depth is about 5cm by taking the stalk as a circle center at an upslope surface of a tsaoko amomum fruit bush with a distance of 15-20 cm away from the stalk, and covering the trench by using surface soil or withered and rotten leaves after performing fertilization in the trench; step II, in early April in the next year, removing the surface soil by taking the stalk as the circle center at the upslope surface of the tsaoko amomum fruit bush with a distance of 15-20 cm away from the stalk when new stems begin to develop and flowers begin to gradually bloom, performing arc fertilization for the second time, and then covering by using the surface soil or the withered and rotten leaves; and step III, in early July in the next year, fertilizing for the third time by using the same method as the step II in a fruit developmental period of tsaoko amomum fruit. By adopting the tsaoko amomum fruit fertilization method disclosed by the invention, the growth conditions of tsaoko amomum fruit plants, the yield of tsaoko amomum fruit and the volatile oil content of tsaoko amomum fruit can be improved.
