Embodiment Construction

[0016] The sea cauliflower community recovery method disclosed in the present invention is mainly aimed at the recovery and reconstruction of the sea cauliflower community in the lakeside area. It includes four steps: 1. seed collection and storage, 2. seed germination, 3. seedling cultivation and 4. field planting. Each step is specifically as follows: 1. Seed storage: collect sea cauliflower fruits (seeds) and store them at a temperature of 4±1°C and a humidity of >80%. 2. Seed germination: Take out the refrigerated fruit, remove the peel, take out the seeds, put them in a 60-mesh sieve, rinse with water for 15-30 minutes, and the water temperature is <30°C; then, put the seeds at a temperature of 25-30°C under light Under the conditions of 1000-5000Lux and light-to-dark ratio of 24h: 0 h to 12 h: 12 h, the rapid germination or germination can be promoted. Using the above germination method can improve the germination rate of seeds and can effectively control the germination...

Abstract

The invention has the following beneficial effects: by artificial collection of ottelia acuminate seeds, artificial acceleration of seed germination, artificial seedling culture and field planting, population is restored through artificial intervention to avoid damages to ottelia acuminate colonies caused by field environment deterioration; the vegetation in the lakes wherein ottelia acuminate islocated is restored while restoring ottelia acuminate, so that the population is richer; and besides, a restoring method disclosed by the invention is also suitable for restoring colonies of other submerged plants through proper adjustment.

Description

technical field [0001] The invention relates to a vegetation recovery method for submerged plants in a lakeside zone. Background technique [0002] Sea cauliflower is a kind of submerged plant, mainly distributed in lake water bodies in the southwest of my country. The phenomenon of sea cauliflower has evolved from bisexual flowers to unisexual flowers, and the number of stamens and styles has decreased, which is of scientific value for the study of the evolution of its family and genus. At the same time, the morphological variability and variability of the population are also very meaningful for the study of the correlation between ecological factors and morphogenesis. In addition, sea cauliflower also has high ornamental value and use value because of its unique appearance and delicious taste. However, due to water pollution and human destruction in recent years, the sea cauliflower community in the lake has seriously degraded, and some even disappeared. In order to prote...
