Problems solved by technology

[0004] However, there is still no very practical and effective method for how to remove shrublandization. Most managers start from the mechanism of the complex internal and external driving factors of shrubby formation, and test and explore how to control the development of shrubby, such as using The further expansion of the bush is controlled by means of enclosure, grazing prohibition and bush mowing
However, the current methods have two deficiencies. First, many methods have not successfully curbed the development of ...

Embodiment Construction

[0025] It should be pointed out that the following detailed description is exemplary and is intended to provide further explanation to the present application. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0026] The applicant found that after three years of mowing the shrubby grassland with a small harvester, the height and coverage of the Caragana microphylla shrubs were 60% of the unmown shrub patches, and the shrub patch size was reduced by 60% , the aboveground biomass was only 25% of the latter, and the herbaceous coverage and herbaceous biomass of the substrate both increased compared with those before mowing, which were 4.3% and 13%. These data suggest that mowing was instrumental in grassland restoration, suppressing shrub growth and promoting herbaceous growth. After mowing, the branch branches of the shrubs basically disap...

Abstract

The invention relates to a method for efficiently inhibiting grassland shrubby, which comprises the following steps: carrying out first mowing from mid-to-late July to early August, and carrying out second mowing in the flowering period of Caragana microphylla in the second year; monitoring the coverage of the shrub before the second mowing; and when the shrub coverage is less than 10%, cradling is not carried out any more in the current year. The method is easy and convenient to operate and high in implementation speed, and a harvester driver can master the operation method skillfully; the cost generated by cutting is compensated by the collected pasture, so that no extra cost is generated and even profits can be made; caragana microphylla shrub branches on the earth surface can be efficiently removed; enclosing and grazing forbidding are not needed, and the influence on production is small; under annual unmanned aerial vehicle monitoring, the shrub level can be kept at a low degree, and the pasture yield is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of shrub expansion, and in particular relates to a method for efficiently suppressing grassland shrub formation. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Shrubification is the phenomenon of increased density, cover and biomass of shrubs. Shrubbery has become the most important way of vegetation type change in arid and semi-arid areas, especially in grasslands in pastoral areas, which has caused a reduction in the amount of pasture that livestock can eat, which has seriously affected the ecosystem and the sustainability of the livestock industry. Continuous development. ...
