Problems solved by technology

[0004] In the experimental research of aquatic plants, it is more common to use the top 10-15cm of the plant to germinate into new plants, but so far there has been no report at home and abroad on the rapid propagation of P. spicanus using a single node

Embodiment Construction

[0018] In September 2004, the provenance of Foxtail algae was collected from Jiangpu County, Nanjing, cleaned, and the branches 5-30cm away from the tip were selected. On the basis of keeping the complete leaves, they were cut off by single node, and the upper end of each node kept the stem 0.5-1.0cm long, 1.5-2.0cm reserved at the lower end. These joints were transplanted in the substrate that the lower part is lake mud and the upper part is sand subsequently, and the cultivation container is a small plastic pot, and the water depth is kept at 3 cm. Provide artificial light, the intensity is 6000lx, the light time is 14 hours / day, and the temperature is about 25°C. Change the water every 2 days during this period. After observation, new shoots germinated after 2 days, and some new roots grew out. After 7 days, the number of new shoots sprouted from 240 nodes was 284, and the number of new plants was 206. Most of the shoots were 1-2cm long. 118%, and the single node germinat...

Abstract

The present invention is characterized by that said invention utilizes the characteristics of that myriophyllum spicatum has stronger germination capability, under the natural condition said invention has no need of using hormone and chemical drug to make treatment, and can make plant implement monomerous success germination and be grown into health engineering seedling.

Description

1. Technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a method for rapidly producing high-quality engineering seedlings of P. spicanus. 2. Background technology [0002] Myriophyllum spicatum Linn. is a perennial aquatic herbaceous plant of Myriophyllum spicatum Linn., which is widely distributed in lakes, rivers, reservoirs, ditches or rice fields. The plant has a high tolerance to water pollution, and is often used as a water purification tool species and a vegetation restoration pioneer species in eutrophic water ecological restoration projects. The plant is also widely planted in fish, shrimp and crab ponds for bait and to provide necessary shelter and spawning grounds. In addition, the plant is also a commonly used landscaping material in the process of indoor ornamental aquaculture. [0003] At present, there is a great demand for the seedlings of P. spicanus in the market. However, the researches on P. sp...
