A method for preparing riparian soil organic carbon source by using agricultural and forestry waste

Abstract

The invention discloses a method for preparing a riparian zone soil organic carbon source from agricultural and forestry wastes. The method includes steps: 1) prospecting natural geographical conditions of a riparian zone to obtain water level annular cycle changes; 2) seedbed preparation, to be more specific, grinding the agricultural and forestry wastes, subjecting to composting along with animal manure proportionally, fermenting, and proportionally well mixing with soil; 3) plant propagation, to be more specific, selecting paspalum notatum and cynodon dactylon for mixed sowing, performing cuttage of hemarthria compressa and transplanting of cyperus rotundus; 4), daily maintenance including moisture, nutrient and pest and disease management in a plant seedling stage; 5) plant transplanting; 6) mowing before water flooding, to be more specific, trimming before water flooding to keep the plant height; 7) performing management and protection in the next year, and performing complementary planting in areas with dead trees and trees in poor growth vigor; 8) extensive management, to be more specific, spraying bactericidal agents and fertilizing. The method is feasible and convenient and simple in operation, the denitrification capacity of a riparian zone ecological system is improved while ecological slope protecting construction of the riparian zone is realized, and ecological functions and ornamental characteristics of the riparian zone are realized.

Description

technical field [0001] The invention belongs to the technical field of ecological environment management, and more specifically relates to a method for preparing riparian soil organic carbon sources by using agricultural and forestry waste, which is suitable for ecological restoration and reconstruction of riparian zones with severely degraded soil and clay-based substrates, while taking into account the river banks Green construction with ecological slope protection. Background technique [0002] The riparian zone, also known as the riparian zone, water level fluctuation zone, etc., is a special area where some land is periodically flooded and exposed to water due to seasonal water level fluctuations in rivers, lakes, and reservoirs. The unique ecohydrological process, biogeochemical process and biogeographic flora of the riparian zone have important practical and potential value for the interception and removal of non-point sources such as nitrogen, phosphorus, and sedimen...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to solve the problems such as the lack of organic carbon source in the soil, the scarcity of vegetation, the poor overall landscape effect of the riparian zone, etc., with the riparian zone where part of the soil is seriously degraded and the matrix is ​​mainly clay. The purpose of the invention is to The purpose is to provide a method of using agricultural and forestry wastes to prepare riparian soil organic carbon sources while taking into account the construction of ecological slope protection in the riparian zone. The method is easy to implement and easy to operate. Nitrogen removal capacity, while taking into account the ecological slope protection construction of the riparian zone, to achieve the ecological function and ornamental characteristics of the riparian zone
