Method for culturing potamogeton crispus by compound substrate

Abstract

The invention relates to a method for culturing potamogeton crispus by a compound substrate. The problems of potamogeton crispus culture and water quality purification effect improvement can be effectively solved. The method comprises the following steps of collecting potamogeton crispus with roots, stems, leaves and tender shoots from an artificial lake to be used as potamogeton crispus plants tobe cultured; flushing dirt on the potamogeton crispus plants and silt and zooplankton and phytoplankton attached onto the plants by tap water; performing habituated culture in distilled water; preparing a culture device; firstly installing a supporting layer; then, uniformly arranging Lanzhiwang (special soil) onto the supporting layer; next, uniformly arranging rainbow stones onto the upper layer of the Lanchiwang; planting the potamogeton crispus plants onto the junction of the Lanzhiwang and the rainbow stones, so that the stems and the leaves maintain the extending state; adding artificial lake water; performing habituated culture; then, transplanting the plants into rivers and lakes to grow for water quality purification. The method provided by the invention is novel and unique; themethod can be effectively used for potamogeton crispus habituated culture; the water purification capability of the potamogeton crispus is improved; the water quality of the river and the ecological environment can be favorably protected; the economic and social benefits are huge.

Description

technical field [0001] The invention relates to plant cultivation, in particular to a method for cultivating smilax with a composite substrate. Background technique [0002] Scallop grass, also known as: shrimp algae, shrimp grass, wheat yellow grass. Eyeletaceae, eyelet genus. Monocotyledons. Latin name: Potamogeton crispus. Perennial submerged herb. Born in ponds, lakes, streams, there are many still water ponds or ditches, the stems are flat and round, with branches. Leaves lanceolate, apex obtuse, leaf margin wavy and serrated. With petiole, without petiole. Inflorescences spicate. It germinates in autumn, grows in winter and spring, blooms and bears fruit from April to May, and gradually declines and rots after June in summer. At the same time, it forms scaled branches (winter buds) to survive the uncomfortable environment. The winter buds are hard, with teeth on the edge, shaped like a pine cone, and begin to germinate and grow when the water temperature is sui...

Problems solved by technology

However, there are few public reports on the research on which substrate the growth of Smilax is most conducive to the reduction of nitrogen and phosphorus content in the water body.

[0004] And in recent years, the eutrophication of rivers and lakes has caused widespread concern from all walks of life, especially the pollution of water quality. How to improve the water quality purification effect by using S. In order to purify water quality, it is necessary to cultivate a weed with good growth and good water purification effect, and the key to the cultivation of weed lies in the culture substrate. How to combine the culture medium with the growth of weed has not been publicly reported so far.
