Method for ecological restoration of marginal land of loess plateau by using energy crop triarrhena lutarioriparia

Abstract

The invention relates to a method for ecological restoration of marginal land of the loess plateau by using an energy crop triarrhena lutarioriparia, which comprises the following steps: S1, collecting and collating a spatial distribution map of meteorological data in the loess plateau region in recent years and an existing land type map of the region in combination with a regional map meeting thegrowth conditions of the triarrhena lutarioriparia, using geographic information system software for map layers piling, map layers piling the mentioned three maps, and determining the region suitablefor ecological restoration by using energy crop triarrhena lutarioriparia; S2, dividing the suitable restoration region determined in the step S1 into three types of marginal land to be restored according to land types; and respectively carrying out ecological restoration on the three types of marginal land to be restored by adopting different triarrhena lutarioriparia planting methods. The method for ecological restoration of marginal land of the loess plateau by using energy crop triarrhena lutarioriparia has the advantages that, a suitable method for planting and restoring the triarrhena lutarioriparia is configured according to different types of marginal land of the loess plateau region and local conditions, and economic benefits are generated by the harvest of biological refining raw materials and biomass power plant raw materials on the ground every year, so that the economic benefits and the ecological benefits are both achieved.

AI Technical Summary

Benefits of technology

In this patented method described in the patented text, there were various ways to enhance or restore ground fertility without causing harmful side reactions like deforestations. By utilizing specific techniques based upon factors like sunlight availabilities, nitrogen levels, mineral concentrates, and other factors, these processes resulted in significant increases in yields compared to traditional farming practice. Overall, this technology provides technical means for creating stable and economical grassland production bases.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the ecology equilibrium between different regions within the Lesser Land (Loess Plane) during periods when rainwater from both urban parts can be absorbed into fresh wetland or underground without causing harmful effects like decreased crop yields due to overgrazing crops. Existing solutions involve adding expensive fertilizers or reducing sedimentary basin depth, making them less effective at reconstructing ecosistence around these zones.
