Problems solved by technology

The operation of winter bud propagation is relatively simple, but there are fewer and fewer winter buds in natural lakes, which cannot meet the large demand at all.
It is difficult to propagate the cuttage method of the sarcocarpus, and the explants cannot grow roots and survive for a long time after direct cutting.

Embodiment example

[0033] Implementation case: a kind of breeding method of the present invention comprises the following steps:

[0034] 1. Collect the plants with good growth status and no pests and diseases.

[0035] 2. After collection, wash with clean water 3 times to wash off the attachments on the fresh plant surface.

[0036] 3. Cut the plants of S. chinensis into 10-15 cm long explants.

[0037] 4. Preparation of Hoagland culture medium. Hoagland's culture medium includes: Hoagland's basic elements, indole butyric acid 1mg / L, 6-benzylaminoadenine 1mg / L.

[0038] 5. Put the cut explants into Hoagland medium for culture. At a room temperature of 25°C and a day-to-night ratio of 1:1, culture for 15 days.

[0039] 6. After 15 days, the new root system is 2 cm long, and the lateral buds grow 5 cm. Take it out of the culture medium and rinse it with clean water once. Planted in nursery fields for cultivation.

[0040] 7. Keep the water depth at 40 cm, the water temperature at 15-30°C, c...

Abstract

The invention discloses a propagation method for submerged plant potamogeton pectinatus L, comprising the following steps: culturing the potamogeton pectinatus L in the Hoagland culture solution; inducing roots to grow when adding 0.5-2mg / L of indolebutyric acid; and inducing lateral buds to grow when adding 0.5-2mg / L of 6-benzylaminopurine. After being cultured for 15-20 days indoors, the potamogeton pectinatus L is transplanted to a seedling field to be cultured for 30-35 days; after the plant grows to 20-30cm, the potamogeton pectinatus L is transplanted to the target water. With simple operation and high survival rate, the propagation technology for potamogeton pectinatus L solves the problem that the explants of the potamogeton pectinatus L cannot root when being propagated.

Description

technical field [0001] The invention belongs to the field of biological technology, and in particular relates to a method for propagating submerged plant sargassum. Background technique [0002] Potamogeton pectinatus L is a perennial herbaceous submerged plant, which is distributed in all provinces of my country. Also known as: Red Thread Sprout, Longxuyan Zicai. Grate-toothed eye vegetable The eye vegetable belongs to the Potamogetonaceae family (Potamogetonaceae) and the genus Potamogeton. In recent years, with the aggravation of eutrophication in lakes, there are fewer and fewer submerged plants. In order to effectively curb the deterioration of water quality, people have adopted a series of engineering measures. Planting submerged plants to restore aquatic vegetation is a commonly used and effective engineering measure in China. Pteris chinensis is one of the commonly used species for restoring aquatic vegetation. [0003] At present, the propagation method of propa...
