The method for producing the pure female seeds of industrial hemp pure female seeds comprises the following steps that 1, conventional maintenance is carried out after field planting of female plants; 2, colloidal silver-containing male inducing solution is prepared; 3, the colloidal silver-containing male inducing solution is sprayed to the female cannabis hemp in the flowering phase; 4, after 7-14 days, the plants subjected to male inducing treatment become male plants, the pistil and calyx parts start to grow pollen sacs, and when the pollen is mature and the calyx is opened, the pollen is collected; and 5, the pollen is sprayed to flowering parts of female plants, the seeds are mature 4-5 weeks after pollination, and the industrial hemp pure female seeds are obtained. According to the method for producing the pure female seeds of industrial hemp pure female seeds by using the colloidal silver-containing male inducing solution, components for improving the water-retaining property, the stability and the permeability are added into the colloidal silver-containing male inducing solution, so that the seed yield and the female rate are improved, and the germination rate of produced female seeds is higher.
