Eel grass root stem sterile culturing and engineering seedling fast reproducing method

Abstract

A method for the aseptic culture of vallisneria used for restoring the aquatic ecosystem and providing the good to fish, shrimp and crab and the spawning site for them, and the fast reproduction of its engineering seedlings is disclosed, which features use of tissue culture and enlarged reproduction.

Description

1. Technical field [0001] The invention belongs to the field of biotechnology, and relates to a method for rapidly propagating high-quality engineering seedlings of bitter grass. 2. Background technology [0002] Vallisneria natans (Vallisneria natans) is a submerged herbaceous plant belonging to the genus Vallisneria natans. It grows in waters such as rivers and lakes with high transparency, deep silt, and slow water flow. This species has strong water purification ability and high tolerance to water pollution. It is often used as a pioneer species to purify water quality in aquatic ecosystem restoration and reconstruction projects. This species also contains more nutrients, so it is also a common bait for fish, shrimp and crabs, and in the breeding pond, this species can provide the above-mentioned aquatic products with places for spawning, molting and refuge, so it can be widely used in fish, shrimp and crabs. farming. At the same time, this species is also a decoration...

Problems solved by technology

On the one hand, a large number of salvage can easily lead to the destruction of the original habitat; on the other hand, the bitter grass in the natural habitat often contains various algae and bacteria, which is likely to cause pollution of the transplanted habitat and errors in related physiological and ecological experiments, which is also not conducive to indoor viewing

Of course, at present, there are seeds of bitter grass to sow to make up for the lack of provenance, but this requires a suitable aquatic environment and a long time
