Method for establishing plant community in North China

A plant community and construction method technology, applied in the field of plant community construction in North China, can solve the problem of ignoring the scientific design of plant communities and post-regulation processing, not fully considering the maintenance and management costs of environmental conditions, and different treatment measures for different types of seeds, etc. problems, to achieve the effect of regulating its own physiological functions, reducing the impact of competition, and ensuring the effective number of seedlings

Problems solved by technology

The main disadvantages are as follows: 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 ecology of plants characteristics of species screening, but did not make a reasonable combination of species of different types and different functions; third, did not take different treatment measures for different types of seeds when treating seeds; fourth, did not fully consider environmental conditions, plant characteristics and The cost of maintenance and management, 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 method for establishing a plant community in North China, comprising the following steps of: selecting seeds of herbaceous plants, shrubs and arbors; processing a part of the seeds; preparing the mixed seeds; preparing the base material mixture; preparing the base material mixture of the seeds; jetting the base material mixture of the seeds; controlling height of the herbaceous plants and densities of the shrubs and arbors; spraying cycocel soup to the herbaceous plants; spraying stress resistant high nutritive foliar fertilizers to the shrubs and arbors; and finally performing routine management. The method can promote the seeds to germinate rapidly and safely, ensure that the artificial vegetations are structurally and functionally stable, effectively shorten the succession period from the artificial vegetations to the natural vegetations and establish the plant community on wound surface of rock-soil and degraded land of side slopes, waste disposal areas and mining areas and the like in North China.

Description

technical field [0001] The invention relates to a method for establishing artificial vegetation, in particular to a method for establishing plant communities in North China. Background technique [0002] The North China region mainly includes Beijing, Tianjin, Hebei, Shandong, southeastern Henan, central and southern Shanxi, parts of Inner Mongolia, Huaibei of Jiangsu, and Huaibei of Anhui, with a total area of ​​670,530km 2 , is one of the main grain bases in my country. However, due to the development of the industrial and mining industry, the salinization of the land in North China has increased, the area of ​​cultivated land has been continuously reduced, and the cultivated land has been seriously degraded. In addition, the development of railways, highways and other transportation constructions has resulted in a large number of rock and soil slopes, which seriously damaged the ecological environment. . The current conventional method for vegetation restoration is to s...
