The invention provides an
astragalus sinicus single-season rice high-yield efficient seed reservation method which comprises the following steps: a, selection of
astragalus sinicus seeds: before
sowing, selecting the same variety of
astragalus sinicus so as to prevent other varieties of
astragalus sinicus from being planted in a range within 2 kilometers; b, treatment of the
astragalus sinicus seeds: before
sowing, insolating the
astragalus sinicus seeds in the sun for half a day to one day, then peeling, selecting the astragalus sinicus seeds through a salt soaking method, and finally washing away the salt on the astragalus sinicus seed with
clean water; c,
sowing: before sowing, digging a perimeter
ditch in a field, and then sowing uniformly; d,
field monitoring before harvesting of seeds: performing prevention and control on weeds and
disease and
insect damage; e, harvesting of the seeds: harvesting by virtue of manual power or a
combine harvester, wherein harvesting is performed when the black
legume rate of the astragalus sinicus is up to 85% during manual harvesting, and harvesting is performed when the black
legume rate of the astragalus sinicus is up to 90-95% during harvesting based on the
combine harvester. The method has the characteristics of being high in seed yield, promoting the rapid
recovery and development of southern
green manure crops, improving the
soil fertility, reducing the application amount of fertilizers, protecting the
ecological environment and the like, and can be used for not only improving the double-
cropping index of the rice field and improving the income of farmers, but also achieving a
soil fertility effect.
