The invention provides a method for improving the self-
reproduction capability and yield of naturally-growing stipa capillata seeds, and relates to the technical field of seed breeding, the method comprises the following steps: S1, investigating
a site, and selecting an area where natural stipa capillata grows
alopecia areata or grows unevenly; s2, supplementing water, namely supplementing water to the natural stipa capillata growth area by adopting arrow
insertion micro-spraying; s3, sunshade net blocks are laid, specifically, the sunshade net blocks are laid at the sparse or blank positions of the naturally-growing stipa capillata at the
plant row spacing of 50-70 cm; s4, compacting the middle and four corners of the sunshade net block; s5, when the stipa capillata above the sunshade net grows to 7-10 cm, the sunshade net blocks are removed; s6, management and protection; the lower ends of stipa capillata caryopses are as thin as needles, the surfaces of the stipa capillata caryopses are densely provided with inverted hairs, the caryopses are shaken, and the caryopses can be easily hung on the sunshade net block, penetrate through meshes and are inserted into ground soil, so that
seed implantation, rooting and
germination are realized, plants in a sparse area or blank land of natural stipa capillata are increased, and the
vegetation growth of the natural stipa capillata is recovered.
