Rapid eelgrass herb culture method

Abstract

The invention discloses a rapid eelgrass herb culture method which includes the steps: culturing eelgrass herb corms; screening rapidly grown varieties in a fixed excellent culture environment; takingrapidly grown eelgrass herbs as initial culture seedlings in each generation; continuing to culture the initial culture seedling in the fixed excellent culture environment; collectively acceleratingculture of the eelgrass herbs from gene natures and environments.

Description

technical field [0001] The invention relates to a kind of bitter grass cultivation, in particular to a quick cultivation method of bitter grass. Background technique [0002] Bittergrass is a submerged herbaceous plant of the genus Bitterwort in the family Hydrochariaceae. There are 5 species found today, including Bitterwort, Bittergrass densely toothed, Bittergrass thorns, Bittergrass Asia and Bittergrass. Bitterweed is widely used in many types of water bodies in my country It can survive in any medium and has a wide range of tolerance to water environments. Bittergrass is often used as a bait resource for artificial breeding of fish, shrimp and crabs. It is also commonly used for aquarium viewing. As a higher submerged plant, Bittergrass is one of the primary producers in the aquatic ecosystem. It has water purification and The ability to slow down the release of nutrient salts has an allelopathic effect on algae and can inhibit the growth and reproduction of algae. In ...

AI Technical Summary

Problems solved by technology

At present, the materials of bitter grass are obtained directly from rivers, lakes, reservoirs, and breeding ponds, or indirectly through winter buds, seeds, and tissue culture. At present, wild resources have been depleted in large quantities; however, the tissue culture technology of Erythrina fragrans has limitations such as high cost, long cycle, and high operation requirements.

With the gradual maturity of aquatic ecological technology, the rapid increase of successful engineering cases, and the increasing demand for technology promotion, the demand for bitter grass will show a blowout growth. The current availability of bitter grass resources will not be able to meet future engineering applications.
