Plant community constructing method in northeastern area

A plant community and construction method technology, applied in the field of plant community construction in Northeast China, can solve the problem of not fully considering environmental conditions, plant characteristics and maintenance management costs, ignoring the scientific design of plant communities and post-regulation processing, and not distinguishing between different types of seeds. To achieve the effect of regulating its own physiological functions, reducing the level of inter-species competition, and reducing the impact of competition

Problems solved by technology

The patent has 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 screening 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 very 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 plant community constructing method in the northeastern area, which comprises the following steps of: selecting herb, shrub and arbor seeds; treating seeds difficult to sprout; preparing a seed mixture; preparing a base material mixture; preparing a seed and base material mixture; spraying the seed and base material mixture to rock-soil wound surfaces or degraded lands; controlling the height of herbs and the density of shrubs and arbors; spraying paclobutrazol liquor to the herbs; spraying a stress-resisting foliage fertilizer to the shrubs and the arbors; and conventionally managing moisture and nutrients. The method ensures fast and safe seed sprouting, guarantees stable structure and functions of artificial vegetations, and shortens the succession period of the artificial vegetations into natural vegetations. The plant community constructing method is used for the rock-soil wound surfaces or the degraded lands, such as side slopes, waste disposal areas, mining areas and the like in the northeastern area.

Description

technical field [0001] The invention relates to a planting method of artificial vegetation, in particular to a plant community building method in Northeast China. Background technique [0002] Northeast China includes Heilongjiang Province, Jilin Province, most of Liaoning Province and the eastern part of Inner Mongolia Autonomous Region, with a total area of ​​996230km 2 , is an important agricultural, forestry and animal husbandry production base, energy base and heavy industry base in China. However, due to the rapid consumption of resources and the deteriorating environment due to the development of industry and mining economy and the process of urbanization, it has become a typical area of ​​extensional economic development in my country at the cost of exhausting a large amount of natural resources and seriously damaging the ecological environment. Strengthening regional ecological environment governance and using vegetation as the main technical means is an important ...
