Method for cultivating vallisneria natans seedlings

Abstract

The invention discloses a method for cultivating bitter weed seedlings, which comprises the following steps: digging the seedbed to a depth of 8 to 10 centimeters, breaking the soil blocks, adding 0.3 to 0.5 kilograms of humus per square meter of the seedbed, stirring evenly, and then feeding the seedlings Add water to the field, and add bleaching powder to the water for disinfection; choose bitter grass with a plant height of 15 to 20 cm as seedlings, put them in the disinfection pool and soak them for 6 to 10 minutes; The seedlings are one-pot, spray the hormone combination solution on the seedbed, and then cover the seedlings with a film; control the water temperature in the nursery field to be 15 to 30 degrees, and when the seedlings are transplanted into the nursery field for 48 to 52 days, the new growth formed by the rhizomes will form. The bitter grass seedlings will grow to a plant height of 10 cm; remove the film covering the bitter grass seedlings, add water to the seedbed, keep it for 9 to 11 days, and move the seedlings out of the nursery field to obtain the bitter grass seedlings. The method of the invention breaks the season limitation of Erytheria galerica planting, and overcomes the disadvantages of high cost, long period and high operation requirements in its tissue culture technology.

Description

technical field [0001] The embodiment of the present invention relates to a method for cultivating plants, in particular to a method for cultivating bitter grass seedlings. Background technique [0002] Vallisneria natans (Vallisneria natans) is a submerged herbaceous plant of the genus Vallisneria genus in the family Hydrochariaceae. There are currently 5 species found, including Vallisneria natans, Vallisneria natans, Vallisneria natans, and Vallisneria natans. Vallisneria natans is widely distributed in my country. It can survive in many types of water bodies 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 ...

AI Technical Summary

Problems solved by technology

[0005] 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.
