Phosphorous-rich region phosphorous loss prevention and control plant community disposition method

Abstract

The invention provides a phosphorous-rich region phosphorous loss prevention and control plant community disposition method. The phosphorous-rich region phosphorous loss prevention and control plant community disposition method comprises the following steps of, firstly, determining the area of a mountainous region severe in water and soil loss and rich in phosphorous; secondly, determining plantsplanted in the area of the mountainous region severe in water and soil loss and rich in phosphorous in the first step; thirdly, according to the dynamic features of seasonal change of nutrients of theplants in the second step, selecting appropriate plant species to be deposed, and according to the difference of plant functional groups in different habitats, performing community division, selecting plants applicable to being gathered together to provide a scientific basis and the like for vegetation recovery. The phosphorous-rich region phosphorous loss prevention and control plant community disposition method is mainly applied to mountain water and soil loss and phosphorous-rich region phosphorous output to structure low-cost and high-efficiency effective plant communities, thereby beingapplicable to basin water and soil loss control as well as phosphorous output reduction and control of mountain non-point source pollution.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a plant community configuration method for preventing and controlling phosphorus loss in phosphorus-rich areas. Background technique [0002] How to restore and manage phosphorus-rich soil has become a worldwide problem that plagues human development. The use of chemical and biological modifiers to reduce water-soluble phosphorus is a common method used in the past. Lime, iron salts, calcium salts and aluminum salts are the main chemical modifiers. These methods can play a good role in a short period of time, but these modifiers cannot fix phosphorus for a long time, on the contrary there is a risk of secondary pollution. Likewise, biological fixation has not been effective in reducing the risk of phosphorus loss. There are also studies devoted to screening phosphorus-enriching microorganisms, but because the survival of microorganisms is restricted...
