Construction method of plant community in northwest region

A construction method and plant community technology, applied in the field of plant community construction in Northwest 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, promoting the safe establishment of vegetation, and reducing the impact of competition

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 construction method of a plant community in northwest region, which comprises the following steps: selecting grass, brush and arbor plant seeds; treating seeds which are difficult to sprout; preparing mixed seeds, substrate mixer and seed substrate mixer; spraying the seed substrate mixture on the wound surface of rock soil and deteriorative land; controlling the height of the grass and the densities of the brush and the arbor; spraying uniconazole liquid medicine on the grass; spraying stress resistant high-nutrition foliage fertilizer on the arbor; and daily caring the water content and nutrients. The invention ensures that the seeds are quick and safe to sprout and artificial vegetation has stable structure and functions, effectively shortens the succession period from the artificial vegetation to natural vegetation and is applied to a construction method of the plant community on the wound surface of rock soil and the deteriorative land of side slopes, waste disposal areas, mining areas and the like in northwest region.

Description

technical field [0001] The invention relates to a planting method of artificial vegetation, in particular to a plant community building method in Northwest China. Background technique [0002] Northwest China includes central and western Inner Mongolia, most of Xinjiang, northern Ningxia, central and western Gansu, and the border areas of Shanxi, Shaanxi, Hebei, Liaoning, Jilin and other provinces bordering these places, with a total area of ​​3,450,000 km 2 . In recent years, coal mining, road and railway construction in Northwest China have produced a large number of rock and soil wounds, coupled with severe desertification, shortage of water and soil resources, strong wind and water erosion in Northwest China, and the regional ecological environment is very fragile. Ecological restoration is quite difficult. At present, the common method is to select suitable plant seeds, then mix them with matrix materials (organic fertilizers, soil improvers, etc.) and apply them, and...
