Problems solved by technology

[0003] The purpose of the patent of the present invention is to provide a method for planting submerged plants under the condition of hard substrate and no silt in view of the above problems. By selecting seedlings and cooperating with seedling planting carriers to carry out counterweight planting, this method does not need to cover soil Under the condition of hard substrate and no silt, the problem of difficult rooting of submerged plants is solved, and the survival rate is greatly improved

Embodiment 1

[0013] Take the South Lake of Huizhou West Lake as an example: the lake has a surface area of ​​about 120,000 square meters and a water depth of about 1.7 meters. 70% of the bottom of the lake is hard bottom. In 2007, the lake began to build an ecosystem, including a part of the shore. The earth-covering project was carried out, and the hard bottom area in the middle of the lake was all planted with submerged plants using the patented method. First select the species. The species selected here is Hydrilla verticillata. After the species is selected, the seedling planting carrier is made. A bamboo ring with a diameter of 40 cm is lined in a polyethylene mesh bag with a mesh of 2 cm × 2 cm. After the carrier is made, the black algae is divided into pieces. Each carrier is filled with about 1.5 kg. After the black algae is loaded, the stones are loaded from one port of the mesh bag. The stones are 4 cm in diameter and weigh 500 grams. It is mainly used as a counterweight. After the s...

Embodiment 2

[0015] Take the national "Tenth Five-Year Plan" major scientific and technological project "Taihu Lake Water Pollution Control and Water Body Restoration and Demonstration Project" as an example: the demonstration project is located in the Meiliang Bay Lake area in the north of Wuxi, covering an area of ​​about 2 square kilometers. The difficulty of the demonstration project is: the lake bottom lacks the soft sedimentary mud where plants can take root, and wind and waves cause the rhizomes of submerged plants to break. To solve this problem, we first select the plant Elodea with rapid growth and large biomass, and use this patented method for planting. , To fix the plants on the bottom of the lake to help the plants take roots. After regular monitoring, this method is very effective. It not only reduces the workload, but also strengthens the fixation of the sediment around the plants. The project has successfully passed the acceptance of the Ministry of Science and Technology.

Abstract

The present invention relates to a method for planting a submerged plant under a condition of hardground and non sludge, including three aspects of the selection of a germchit, the preparation of a planting carrier and a method of planting. The selected germchit is a black alga or waterweed; the preparation of the planting carrier is that a bamboo loop with a diameter of 40cm is lined in a polyethylene net bag with a sieve number of 2cm * 2cm; the planting method is that the germchit (black alga, waterweed) of 1.5kg and gravel of 500g by weight which diameter is 4cm are added into the net bag altogether, the net bag is then sunken into a lake bottom. The method is applied for an ecological renovation engineering of hardground non-sludge garden manpower water, a landscape lake and a natural lake. The prominence advantage of invention is that it is capable of resolving a problem that a plant fresh body may be floated above water when transplanting, the plant fresh body is fixed through the net bag, the counterweight stone ensures the plant fresh body to contact with the lake bottom, it is convenient to the rooting of the submerged plant and accelerate the sedimentation of the float sludge. The method has reliable operation performance and low cost.

Description

Technical field [0001] The invention is applied to ecological restoration projects of artificial water bodies, landscape lakes, and natural lakes in parks with hard bottom quality and no silt. Its outstanding advantage is that it solves the problem of plant fresh body floating on the water surface when transplanting. It uses a net bag to restrain and fix the plant fresh body. The weighted stones make it closely contact with the bottom of the lake, which is convenient for submerged plants to take root and promotes floating. Mud settles. The method has the characteristics of reliable operation, strong operation and low cost. Background technique [0002] Due to the serious pollution caused by the lack of water resources, the water quality of the existing urban landscape lakes and natural lakes in our country deteriorated. Soon after the artificial water bodies in the park were built, the transparency of the water bodies decreased and the landscape function was lost. Technology is t...
