Construction method of plant community in Central China

Abstract

The invention provides a construction method of plant community in Central China, comprising the following steps of selecting plant seeds; pretreating 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 shrub and arbor; spraying paclobutrazol physic liquor to herbs; spraying stress resistant high nutrition foliar fertilizer to the arbor; and 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 constructing geotechnical wound surfaces including slopes, abandoned dreg sites and mining places and plant communities of degraded soils in Central China.

Description

technical field

[0001] The invention relates to a planting method of artificial vegetation, in particular to a plant community building method in Central China. Background technique

[0002] Central China includes all or part of Hubei, Hunan, Jiangxi, Anhui, Jiangsu, Zhejiang and other provinces, with a total area of ​​229,643km 2 , is the largest plain area in southern my country. In the process of transportation infrastructure construction, a large number of rock and soil wounds such as slopes and waste dumps are inevitably generated. Due to the complex types of rocks, large slopes, and poor water retention, vegetation reconstruction is difficult. The existing vegetation establishment technology is to first select suitable plant seeds, then mix and apply them with matrix materials (organic fertilizers, soil improvers, etc.), and finally perform water and fertilization management. Chinese patent C N100348086C discloses a method for building evergreen vegetation on the slo...
