A kind of cultivation method of selenium-enriched organic purple water lily

Abstract

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.

Problems solved by technology

[0009] In the traditional water lily cultivation method, the layout of the water lily is unreasonable during the planting process, and the growing leaves cover each other, which affects the light and effect, and the growth of the water lily is poor.

In the process of production management, in order to keep the water lilies growing well, chemical fertilizers need to be applied, and the quality of the harvested water lilies is poor

At the same time, a large area of ​​water lilies is planted in the pond, and the process of picking water lilies is troublesome.

In addition, the nutritional content of conventional water lily flowers is not distinctive
