Method for improving germination rate of zoysia japonica seeds

The invention relates to the technical field of plant cultivation, in particular to a method for increasing the germination rate of zoysia japonica seeds, seeds which are full and healthy and free of defect wounds are selected, in the step (3), glass dishes are laid in a constant-temperature and constant-humidity incubator in a dispersed mode, the germination conditions are that the relative humidity is 80%, the temperature is 25 DEG C, and germination is conducted in a dark place, and in the step (2), the germination rate of the zoysia japonica seeds is increased. The used treating fluid is a solution containing a binder with the mass fraction of 0.02%-0.1%, a water-retaining agent with the mass fraction of 0.1%-0.5% and NaOH with the mass fraction of 0.05%-1%. The method has the advantages of improving the seed coat permeability and water absorption and water retention capacity of the zoysia japonica, improving the seed vigor and enabling the zoysia japonica seeds to rapidly reach a high germination rate st
