Problems solved by technology

However, in the past, people planted Nymphium plants mainly by transplanting plants. This method has a low survival rate and high planting costs due to factors such as water-free transportation and cutting planting difficulties.

Embodiment Construction

[0009] Waternucks and honeysuckle have seed propagation and efficient vegetative propagation systems. The lake survey found that Nymphaeum seeds have a large amount of occurrence, are easy to collect, and have a high germination rate; Nymphium and honeysuckle populations have large biomass, and the tubers of Nymphium and honeysuckle buds are easy to fish for. Nymphaeum and honeysuckle populations usually grow in waters with a water depth less than 2.2m.

[0010] The seeds of Nymphaeum do not need to undergo complicated treatment, and raising the temperature can promote its germination, and the germination rate is high. From June to October every year, the seeds are collected in the growth area of ​​the water lily cluster. Use a boat to paddle to the growth area of ​​Nymphaeum clumps, select the inflorescences with mature fruits, cut them off, pick off the fruits, pack them in plastic bags or woven bags, bring them back, and soak them in 0.1% mercury for 7-15 minutes The frui...

Abstract

The invention provides a method for planting nymphoides plants of nymphoides peltata and nymphoides indica and aquatic vegetation for restoring the wetland, which can form community scale and comprises the following steps of: collection of seeds and tubers of nymphoides peltata, propagation and cultivation of seedlings of nymphoides peltata, collection of brood buds of nymphoides indica and propagation and cultivation of seedlings. The method is characterized in that a seed propagation method or a tuber propagation method is adopted for planting the nymphoides peltata in water body; and the brood buds of nymphoides indica, namely 'chicken toe buds' are adopted for planting the nymphoides indica in water body.

Description

technical field [0001] The invention relates to controlling water body pollution and protecting the ecological environment, in particular to a method for planting waterweed plants to restore wetland aquatic vegetation. Background technique [0002] At present, most water bodies in my country are hyper-eutrophic, and cyanobacteria blooms are serious. The transparency of many water areas is only 20-30cm. Most submerged plant species are difficult to grow, resulting in the destruction of aquatic vegetation and increasing water pollution. Nymphoides peltatum and Nymphoides indica in Nymphoides Seguier are the dominant species of floating leaf plants in most shallow lakes and other water bodies, and are widely distributed in my country. According to long-term field observation results, their It has strong anti-wind and wave ability and water purification ability, so it is often planted as a pioneer species for the restoration of lake aquatic vegetation. After it grows well and the...
