Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] The method for propagating and cultivating submerged plants comprises the steps:

[0034] ①Put the submerged plant propagation and cultivation device in a shallow water level with a water depth of 20-50mm (30mm is the best), cut the submerged plant plants into 50-80mm segments, and use 80-100 grams of fresh grass per square meter to plant Evenly spread on the substrate layer to prevent the planted grass from floating above the water surface, keep the water surface stable and promote rooting and colonization; for submerged water plants, it is advisable to choose each stem node with the ability to trigger roots and long leaf buds, and grow faster. Black algae, Heliconia spicaculata or Elodea are preferred.

[0035] ②5 to 8 days after sowing, adjust the uniformity of sowing, and make the plant stems contact the non-woven fabric layer as m...

Abstract

The invention discloses a submerged plant propagating and culturing device which comprises a bearing support, a buoyancy support and a substrate layer, wherein the buoyancy support is ring-shaped and is arranged on the upper end surface of the bearing support, and the substrate layer is laid on the upper end surface of the bearing support and at least comprises a non-woven fabric layer used for fixing the root system of a submerged plant and a nylon mesh layer arranged below the non-woven fabric layer. The invention also discloses a method for propagating and culturing submerged plants. Compared with the prior art, the invention has the following advantages that a special device is utilized for changing the growing environment in different water depth conditions, and an appropriate growing condition is provided to speed up growth of the submerged plants so as to improve the propagation speed. The submerged plant propagating and culturing device and the method do not have quite high requirements on water depth, the thickness of soft bottom sediment and water flow stability; and the overall cost is low, the operation is simple and convenient, and the submerged plant propagating and culturing device and the propagating and culturing method are applicable to mass propagations.

Description

technical field [0001] The invention relates to a device for propagating and cultivating submerged plants, and also relates to a method for propagating and cultivating submerged plants using the device. Background technique [0002] Submerged plants (submerged plants) refer to large-scale aquatic plants whose plants are all located below the water layer and live in fixation. The leaves of these plants are mostly ribbon-shaped or filamentous, such as Hydrilla, Vallisneria, Myriophyllum, Ceratophyllum, Potamogetoncrispus , Charophyta (Ch-aracoronata), etc., are usually fixed on the underwater substrate by roots, root hairs or fronds, and their leaves also grow under the water surface. The roots of submerged plants are sometimes underdeveloped or degenerated. The epidermal cells of the plant have no cutin or waxy layer, and all parts can directly absorb water, oxygen and other nutrients dissolved in water, and the aerenchyma is particularly developed, which is conducive to the...
