Embodiment Construction

[0014] A method for inducing cuttage propagation by chrysanthemum hormone, the specific implementation method is:

[0015] 1. Collect Smilax plants from irrigation canals, choose plants that grow vigorously and are free from diseases and insect pests, rinse them with clean water 3 times, and remove their surface attachments.

[0016] 2. Cut the cleaned scorpion grass into 10-15 cm long.

[0017] 3. Soak the cut Smilax stem section in distilled water containing 1 mg of naphthaleneacetic acid and 1 mg of 6-benzylaminoadenine for 1 hour.

[0018] 4. After soaking for 1 hour, rinse the Smilax chinensis with clean water once, and cut it into the seedling field.

[0019] 5. The row spacing of the cuttings of S. chinensis is 10 cm. Keep the water depth at 0.4 meters, cultivate for 30 days, the average water temperature is 20°C, and the culture survival rate is 89%.

[0020] 6. When the average length of the plants was 30 centimeters, they were transplanted into landscape lakes wit...

Abstract

The invention relates to a method for inducing radical buds to propagate potamogeton crispus L by using hormones, belonging to the biotechnology field. Roots are promoted to grow by using naphthylacetic acid and buds are promoted to grow by using 6-benzylaminopurine so as to improve cutting survival rate. The operation steps are as follows: (1), collecting stem sections for propagating; (2), preparing and processing stem sections processing drug; and (3), cutting stem sections and managing seedling fields. Compared with winter bud propagation and tissue culture propagation, the method provided in the invention has the advantages of simple operation, low culture condition demands, low investment cost, short propagation period and the like; the potamogeton crispus L propagation cost is greatly reduced; and the method meets the demand that a great number of potamogeton crispus L is needed when recovering aquatic vegetation.

Description

technical field [0001] The invention belongs to the field of biological technology, and in particular relates to a cutting propagation technology of the submerged plant Paleopsis chinensis. Background technique [0002] Potamogeton crispus L is a perennial submerged herb: it is also called shrimp algae and shrimp grass. Potamogetonaceae, Potamogeton. The life cycle of Smilax is different from most aquatic plants. It germinates in autumn, grows in winter and spring, blooms and bears fruit in April to May, and gradually decays and rots after June in summer. At the same time, it forms scales to survive the summer. [0003] With the aggravation of water pollution, it is rare to see the growth of large-scale Smilax in nature. It is of great significance to plant Smilax in aquatic vegetation restoration and water eutrophication control projects. In winter, other submerged plants such as bitter grass, black algae, and sunflower have withered and died in winter. The existence of w...
