Embodiment 1

[0031] The invention provides a submerged plant fixation planting method suitable for mountainous rivers,

[0032] The first step: determine the layout size of the three-dimensional vegetation net 4 according to the width and shape of the river, cut the three-dimensional vegetation net 4, set the three-dimensional vegetation net 4 in the river bottom mud, and the meshes in the three-dimensional vegetation net 4 The smooth surface is perpendicular to the direction of water flow;

[0033] Second step: an overflow dam 1 is arranged on the upstream of the three-dimensional vegetation net 4, and a rockfill area 3 is arranged at the front end of the three-dimensional vegetation net 4, and the three-dimensional vegetation net 4 is fixed by rockfill; the rockfill area realizes The water flow scours and dissipates energy, and at the same time plays a role in fixing the three-dimensional net by pressing stones;

[0034] Step 3: Set submerged plants or submerged plant seeds 2 in the thr...

Embodiment 2

[0039] Example 2 Water Ecological Restoration Project of Tiaodeng River (Jiulongpo Section) in Chongqing

[0040] Tiaodeng River (Jiulongpo Section) is a mountainous river with an average slope of 2.4‰ and an annual average flow of 0.89m 3 / s. In the dry season, the flow rate is small, generally 0.2-0.5m 3 / s, the rainfall is mostly concentrated in May-September, accounting for more than 70% of the annual rainfall, and the daily flow rate in the wet season can reach 0.8-2.0 m / s, so this case is equipped with a well-developed root system, narrow and long branches, and soft anti-scouring type For submerged plants, add three-dimensional nets and other fixed planting measures for submerged plants. At the same time, make full use of the energy dissipation function of rolling dams and rockfills, and fix the three-dimensional nets by pressing rocks locally.

[0041]Regardless of whether it is a submerged plant with mud or washed aquatic plants, it will take a certain period of root...

Abstract

The invention relates to a submerged plant fixing and planting method suitable for a mountainous river. The method includes the steps of 1, determining the layout size of a three-dimensional net according to the width and shape of the river, cutting a three-dimensional vegetation net, and placing the three-dimensional vegetation net in sediment of a riverway; 2, arranging an overflow dam on the upstream of the three-dimensional vegetation net, arranging an enrockment area at the front end of the three-dimensional vegetation net, and fixing the three-dimensional vegetation net through enrockment; 3, placing submerged plants or submerged plant seeds in the three-dimensional vegetation net. According to the submerged plant fixing and planting method, by preparing the anti-scoring submerged plants which are robust in root, long and narrow in branch and soft, additionally adding the three-dimensional vegetation net and the like and locally pressing stone to fix the three-dimensional net, the problems in construction of a submerged plant community of the mountain river and long-term stability of a system are solved.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to submerged plants, in particular to a submerged plant fixation planting method suitable for mountainous rivers. Background technique [0002] Submerged plants play an irreplaceable role in aquatic ecosystems. Submerged plants provide aquatic animals with more living habitats and hidden places, and can increase dissolved oxygen in the water, purify water quality, and expand the effective living space of aquatic animals. At the same time, the young parts of submerged plants can be eaten by aquatic animals. , thereby improving the entire aquatic ecosystem. People pay more and more attention to the role of submerged plants in water ecological restoration, especially in improving water visibility and landscape construction. Commonly used submerged plants are planted as follows: [0003] 1. Fork planting method [0004] Generally, a bamboo pole or wooden pole with a fork is used as a tool...
