Description
Technical Field
The invention relates to the technical field of grass planting, in particular to a method for planting, expanding and propagating aquatic grass plants.
Background
The grass of Manchurian wildrye (also called Chuanmanzao), which is a kind of salt-tolerant vascular bundle plant growing in high-salt water area and with soft soil at the bottom, rich in organic sludge and capable of absorbing nutrients in water and bottom sludge under proper temperature and illumination conditions.
In the prior art, the grass grows in a culture water area, and absorbs the vegetative growth, branching and tendril climbing in the bottom mud of the water body to spread at a proper temperature and a proper water depth by illumination, thereby converting, degrading and eliminating the organic harmful components harmful to the growth of prawns in the culture water body, and playing an important role in regulating, improving and protecting the culture water quality environment. By detecting the pond for growing the grass, the nitrite harmful to the cultured prawns is 0.01mg/L, the ammonia nitrogen is 0.2mg/L, the dissolved oxygen is more than 5-6 mg/L, the water quality of the pond without the grass growth is 3-4 times higher than the relevant indexes, and the dissolved oxygen is particularly 3mg/L or less than the bottom layer. The cultivation water area grows the ditch grass plants with proper quantity and density, plays a role in shading and inhabiting the growth of the prawns in high-temperature seasons, and the prawns like to inhabit in the ditch grass. During the bud stage of the growth period of the grass, the grass can also be used as the food of the prawns to be foraged by the prawns.
However, in a culture water area or a pond, the growth of the hooked grass is not controlled and is allowed to spread, a large amount of water space is occupied, the cultured prawns are also unfavorable, and when the plants age and die, the plants can decay, the substances in the plants are reduced into the water, and the water quality is influenced; the furrow grass is an annual plant, grows by depending on seed reproduction, blooms and produces seeds in 7 months every year, the temperature is reduced after autumn, plant bodies die, together with the seeds, the plant bodies sink into bottom mud at the bottom of the water, the water temperature gradually rises along with the change of the weather in 4 months in spring, and the furrow grass seeds in the shallow water area begin to germinate and grow under the illumination condition; the seeds of the plant are small, sink into the bottom mud, are not easy to collect, are popularized for cultivation and planting, and are difficult to promote prawn cultivation.
