Problems solved by technology

The above-mentioned patents have the following disadvantages: First, the technology focuses on the selection and implementation of engineering measures, as well as the preparation of matrix materials, while ignoring the scientific design of plant communities and subsequent regulation and treatment; second, only based on some basic living habits and ecological conditions of plants species selection based on their biological characteristics, but did not rationally combine species of different types and functions; third, when treating seeds, did not take different treatment measures for different types of seeds; fourth, did not fully consider environmental conditions and plant characteristics As well as maintenance and management costs, the specific species selected are not highly adaptable; fifth, in the later stage of vegetation establishment, there is a lack of technical means such as growth and competition regulation, and improvement of stress resistance

Abstract

The invention provides a construction method of plant communities in the southwest area, which comprises the steps of selecting seeds; processing seeds which are difficult to germinate; preparing a mixture of seeds; preparing a mixture of substrates; preparing a mixture of seed substrates; spraying the mixture of the seed substrates towards rock soil wound surfaces or degenerated land; controlling the height of grasses and the density of bushes and arbors; spraying chlormequat chloride liquor to the grasses; spraying stress resistant high-nutrition foliar fertilizer to the arbors; and carrying out daily water and nutrient management. The seeds have rapid and safe germination, the structure and the functions of artificial vegetation are guaranteed to be steady, and the succession period from the artificial vegetation to natural vegetation is effectively shortened. The invention relates to the construction method of the plant communities on rock soil wound surfaces and in the degenerated land of side slopes, spoil areas, mining sites and the like in the southeast area.

Description

technical field [0001] The invention relates to a planting method of artificial vegetation, in particular to a plant community building method in Southwest China. Background technique [0002] Southwest China includes Sichuan Province, Yunnan Province, Guizhou Province, Chongqing City and Tibet Autonomous Region, with a total area of ​​2,500,000km2. Due to its unique landform characteristics, the southwest region has serious soil erosion and frequent natural disasters such as landslides and mudslides. In addition, the southwest region is rich in mineral resources. Mining has caused a large number of exposed slopes, and the construction of cascade hydropower stations has also produced a large amount of waste residue. In addition, the construction of railways and highways has produced a large number of artificial wounds, making the ecology of the area very fragile. Building artificial plant communities to prevent natural disasters and restore damaged wounds has become an inevi...
