The invention mainly relates to the technical field of aquatic planting, and discloses a planting method of
selenium-enriched
calla palustris. The planting method of the
selenium-enriched
calla palustris comprises a
seedling period, a tillering period, a
bulb formation period, and a mature period. The method is simple and easy for operation, the yield of the
calla palustris reaches 4633kg / mu, andthe
selenium content reaches 7.42 [mu]g / 100g, so that the yield and the quality of the calla palustris are significantly improved; during the
seedling period, blackfish is stocked to a calla palustrisfield, so that
temperature difference between day and night is reduced, and
oxygen content and
organic matter content of soils are increased, thereby promoting the survival and growth of the calla palustris, besides, the blackfish has a high selenium enriching ability, and metabolites of the blackfish can provide rich organic matters for the calla palustris, so that the absorption of the calla palustris is promoted, and the selenium content of the calla palustris is improved; and meanwhile, a
growth promoting fertilizer is spread to the calla palustris, so that
nutrition is balanced, coordinating absorption of external nutrients by the calla palustris and the blackfish is promoted, and the organic selenium content in the calla palustris is improved; and during the tillering period, plantash is regularly spread to the calla palustris field, so that diseases and pests can be killed, and sufficient nutrients are provided for the calla palustris, thereby accelerating the growth of callapalustris plants.
