Problems solved by technology

From the content of the above patents, it can be seen that the following shortcomings are common in the current methods of vegetation establishment on rock-soil wounds such as slopes: First, the technology focuses on the selection and implementation of engineering measures and the preparation of matrix materials, while ignoring the plant community Scientific design and post-regulation treatment; second, species selection is only carried out based on some basic living habits and ecological characteristics of plants, but species of different types and functions are not reasonably combined; third, when seed treatment is not targeted Different treatment measures are adopted for different types of seeds; fourth, environmental conditions, plant characteristics, and maintenance and management costs are not fully considered, and the specific species selected are not adaptable; fifth, in the later stage of vegetation establishment, there is a lack of growth and competition regulation, and Improving resilience and other technical means

Abstract

The invention provides a construction method of plant community in South China, comprising the following steps of selecting plant seeds of grasses, shrub and arbor; treating a part of the seeds; preparing a seed mixture; preparing a substrate mixture; preparing a seed and substrate mixture; jetting the seed and substrate mixture; controlling the herb height and the density of the shrub and the arbor; spraying paclobutrazol physic liquor to herbs; spraying stress resistant high nutrition foliar fertilizer to the arbor; and finally, carrying out conventional management. The invention can promote the seeds to fast and safely germinate, guarantee stable structure and function of artificial vegetation, and efficiently shorten the succession period from the artificial vegetation to natural vegetation, and is used for the construction method of geotechnical wound surfaces including slopes, abandoned dreg sites and mining places and plant communities of degraded soils in the South China.

Description

technical field [0001] The invention relates to a planting method of artificial vegetation, in particular to a plant community building method in South China. Background technique [0002] South China includes Hainan Province, the western part of Guangdong Province, the Pearl River Delta region, and the southern coastal area of ​​Guangxi Zhuang Autonomous Region, with a total area of ​​64896km 2 . South China is a tropical-southern subtropical area with high temperature, rainy weather and evergreen seasons. The temperature in this area is high, the rainfall is large, and pests and diseases occur frequently. How to improve the drought resistance and pest resistance of artificial vegetation is the key technology for regional vegetation construction. The existing method of vegetation construction is to first select plant seeds, then mix them with matrix materials (organic fertilizer, soil improver, etc.), then sow the above mixture, and finally, perform water and fertilization...
