The invention provides a method for cultivating
selenium-enriched organic purple
water lily. In the method, the purple
water lily is used as a cultivated variety, a cultivation tank is established, a special culture medium is prepared, the
water lily is planted in the cultivation tank, the production
management process of the water lily is executed according to an
organic production technological regulations for agricultural products, and biological
selenium agents are sprayed on the water lily in the growing process of the water lily and are converted into organic
selenium in flowers of the water lily under the systemic action of the water lily, wherein the organic selenium is combined with
biopolymer matter; consequently, the water lily which has the advantages of being good in quality, high in security and rich in active substance, namely selenium and having more flowers is produced. Through the method, the water lily is not limited to be planted in a
pool, and the randomness of a cultivation field is high; because the prepared culture medium is high in
fertilizer efficiency, the water lily is free of chemical
fertilizer in the whole growing process and grows well, more flowers are grown, and the flowers are excellent in quality; the biological selenium
fertilizer is sprayed on the water lily at appropriate time, so that the value of nutritional ingredients of the water lily is substantially increased; walkways are arranged in the cultivation field so that people can go deep into the flowers in the appreciation process and can pick the flowers conveniently.
