Planting method of selenium-enriched calla palustris

Abstract

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.

Description

technical field [0001] The invention mainly relates to the technical field of aquatic planting, in particular to a planting method of selenium-enriched calla. Background technique [0002] Calla, a perennial aquatic herb, can detoxify, reduce inflammation, diuresis, and relieve pain; selenium is an essential trace mineral element to maintain human health. It has a strong antioxidant effect and can remove lipid peroxides and free radicals in the body to protect cell membranes and improve Body immunity, resist foreign harmful substances, inhibit cancer cells, delay aging, and promote children's growth and development; however, the selenium content of calla grown by traditional methods is extremely low, which cannot meet people's health needs. SUMMARY OF THE INVENTION [0003] In order to make up for the defects of the prior art, the purpose of the present invention is to provide a planting method of selenium-enriched calla. [0004] A method for planting selenium-enriched c...
