Method for improving yield of tsaoko amomum fruit by spraying sucrose solution

The invention discloses a method for improving the yield of tsaoko amomum fruit by spraying a sucrose solution, and belongs to the technical field of tsaoko amomum fruit cultivation. The method comprises the following steps: spraying a sucrose solution with a certain concentration to inflorescences of tsaoko amomum fruit in a full-blossom period of tsaoko amomum fruit, and artificially increasing flower-visiting rewards of insects to ensure that the attraction to pollinating insects can be increased and the retention time of the pollinating insects on the inflorescences can also be increased, and thus the pollination probability of tsaoko amomum fruit plants can be increased, the fruit setting rate of tsaoko amomum fruit can be improved, and the yield of tsaoko amomum fruit can further be improved. The method disclosed by the invention is simple and convenient, is easy to master, and has significant yield-increasing effects; after a 25% sucrose solution is sprayed by using the method disclosed by the invention, the fruit setting rate of the tsaoko amomum fruit plants can be significantly increased; and compared with a tsaoko amomum fruit group which is not subjected to sucrose solution spraying, the fresh weight of inflorescence fruits can be increased by 69% compared with that of a comparison group, and the dry weight can be increased by 72% compared with that of the comparison group.
