## Abstract

The present invention relates to a method for producing Cannabis sativa L. seed, and more particularly, to a method for producing Cannabis sativa L. seed for efficiently cultivating a low-narcotic Cannabis variety, and when Cannabis sativa L. seeds produced by the production method are used, it is possible to cultivate Cannabis female plants where female flowers are formed, and it is possible to improve the quantity of Cannabis female flowers. Further, when a Cannabis extract is prepared using the Cannabis female flowers, it is possible to prepare a low-narcotic Cannabis extract.

## Claims

### Claim 1

A method for producing Cannabis sativa L. seed capable of cultivating Cannabis female plants, the method comprising:
spraying a first fertilizer composition on soil before sowing Cannabis sativa L. seeds;
sowing Cannabis sativa L. seeds after tilling and preparing the soil on which the first fertilizer composition is sprayed;
inducing the formation of budding flowers by providing Cannabis sativa L. germinated from the Cannabis sativa L. seeds with light, wherein the light is provided under a photosynthetic photon flux density (PPFD) condition of 15 to 20 μMm−2s−1 for 5 to 16 hours for 15 to 30 days: and then providing light under a photosynthetic photon flux density (PFFD) condition of 30 to 40 μMm−2s−1 for 5 to 16 hours for 15 to 30 days;
inducing the formation of male budding flowers in Cannabis female plants by removing all Cannabis sativa L. male plants and retaining female plants where male budding flowers are formed by spraying a second fertilizer composition on Cannabis sativa L. female plants;
after the second fertilizer composition was sprayed the light is provided under a photosynthetic photon flux density (PPFD) condition of 10 μMm−2s−1 for 10 to 12 hours and;
producing seeds by fertilizing pollen in the male budding flowers formed in the Cannabis female plants with female flowers.

### Claim 2 (depends on 1)

The method of claim 1, wherein the first fertilizer composition comprises a nitrogen fertilizer, a phosphate fertilizer, a potassium fertilizer, and porous silica.

### Claim 3 (depends on 1)

The method of claim 1, wherein the second fertilizer composition comprises a nitrogen fertilizer, a phosphate fertilizer, a potassium fertilizer, and porous silica, and
the porous silica is a product in which a mixture of solvent, surfactant aminoethoxyvinyl glycine (AVG), α-aminoisobutyric acid (AIB), and an aqueous silver chloride (AgCl) solution is adsorbed.

### Claim 4 (depends on 1)

The method of claim 1, wherein the female flowers are used as a Cannabis extract by harvesting flowers and flower petals, and the Cannabis extract is low narcotic.

### Claim 5 (depends on 4)

The method of claim 4, wherein the low narcotic comprises tetrahydrocannabinol (THC) in an amount of 0.5 wt % or less in the ingredients of the total extract.

### Claim 6 (depends on 4)

The method of claim 4, wherein the low narcotic comprises cannabidiol (CBD) in an amount of 0.5 wt % or more in the ingredients of the total extract.
