Economical and fast planting method and device for submerged plant eel grass

Abstract

The invention provides an economical and fast planting method and device for submerged plant eel grass. The submerged plant eel grass can be widely applied to the benthophyte planting fields of waterecological restoration and management, underwater desert greening, aquaculture, garden waterscape, aquariums and the like. The device is an eel grass planting frame in the shape of a circular truncated cone, the side face of the eel grass planting frame can be opened and closed, the eel grass planting frame is of a three-section type frame-shaped structure, and eel grass can be thrown to be planted. Each section comprises an upper covers, a side wall and a lower bottom, the upper covers, the side walls and the lower bottoms of the sections are basically identical in shape, the shapes of the upper covers, the side walls and the lower bottoms are designed according to the different growth features of the fibrous roots, the stolons and the leaves of the ell grass and are completely different,the structure is simple, the device can be punched to be formed at a time, and the cost is low. The enframed eel grass can be fast cultivated through a throwing method; compared with a traditional cultivating method, a large quantity of manpower, material resources and time cost can be reduced; meanwhile, courtyards, communities, parks and other hardened bottom water areas can be made into harmonious and ecological gardens.

Description

technical field [0001] The invention belongs to the technical field of water ecological restoration and water ecological balance construction, and relates to a planting device for submerged plants Erythrina chinensis in water ecological construction, in particular to an important link in a system based on water ecological treatment and self-repair——submerged plants An economical and fast planting method of bitter grass. Background technique [0002] In the early and mid-term of my country's reform and opening up, due to people's indifference to environmental protection awareness, various domestic and industrial and agricultural sewage were discharged in a disorderly and rough manner, which degraded and destroyed the ecology of most of the cities and towns and surrounding waters in our country; at present, our country is The whole country strengthens the management and protection of water, and rectifies and eliminates the direct discharge of various sewage from industry, agric...

The shortcomings of this patent are: 1. This method is like inserting a mop for mopping the floor into the mud in the water. When the bitter grass enters the water, the specific gravity slightly smaller than the water and the very soft fibrous roots of the bitter grass will be It will float upward, causing the tip of the fibrous root to be unable to implant in the bed; and the waters where bitter grass needs to be planted are often not clear. A one-dimensional perception method of the magnitude of the transmission force through the bamboo poles, it is impossible to judge the appropriate depth of the bitter grass insertion, some may hang the whole plant in the water, and some may sink the whole plant into the flocculent mud; 2. For planting waters When the bottom mud is relatively thin, it is easy to cause bitter grass to float up and die; 3. It is very time-consuming and labor-intensive to insert manually with the help of boats and tools, so it is not suitable for large-scale promotion and planting

[0008] At present, there is a kind of planting cup (called planting cup and planting basket) for hydroponics on the market for the colonization of bitter grass in the aquarium (see attached Image 6 ), the method is: first put the gravel into the bottom of the cup as a counterweight, and then wrap the base of the bitter grass with a sponge strip of appropriate length. The outer diameter of the wrapped part is larger than the inner diameter of the planting cup, so that friction, so as to prevent bitter grass from falling off from the planting cup; it has the following disadvantages: the fibrous roots are kneaded into a ball, which is not conducive to the rapid growth of fibrous roots; the cup wall railing is flat, and the duty ratio is small, which is not conducive to fibrous roots, The stolon grows outward; in the experiment, it is found that the stolon of the bitter grass is difficult to pass through the sponge layer; after 2cm from the base of the bitter grass, it is the fastest-growing development part of the bitter grass leaf, which is very fragile, and extrusion or damage can easily cause damage to the bitter grass leaf. die

Due to the requirements of the production process, this type of cylindrical planting cup must be conical with a small bottom to facilitate demoulding, but this will easily cause the bitter grass to fall out of the cup

This planting cup is not suitable for underwater planting of bitter grass
