The technical field is as follows:
the invention belongs to the technical field of soil treatment, and particularly relates to a soil roughening method, roughened soil and application thereof.
Background art:
soil coarsening is the malignant development of soil desertification, and is characterized in that under the action of strong wind erosion, fine granular substances in soil are blown and eroded to generate coarse graining evolution, organic matters and nutrients are lost in the process, and the soil function is reduced again. The phenomenon of soil coarsening is commonly found in regions with high human production activity intensity, such as over-herding grassland regions, desertification farmland regions, bare felled forest lands and the like, and the serious grazing sandy grassland is the most serious. China is a big grassland resource country, the grassland area is nearly 400 ten thousand square kilometers, the grassland area occupies more than 40 percent of the national soil area, and the grassland area plays an important role in national economic construction and ecological environment maintenance. At present, about 90% of natural grass is already in various degrees of deterioration, with severe deteriorated desertification accounting for about 60% and still at 200 ten thousand hm per year2Has become increasingly rapid, and the coarsening of grassland soil desertification is a common phenomenon and is increasingly serious to some extent.
The Xingan Lespedeza dauricus (Laxm.) Schind) is a perennial grassy plant of Lespedeza of Leguminosae, is an excellent feeding plant because of strong adaptability and good resistance, and is suitable for optimized selection of desertification control engineering construction by combining biological nitrogen fixation and green manure application because various livestock like young branches like eating. At present, few research works on Xingan Lespedeza have been carried out at home and abroad, and research on the directions of desertification prevention and control application and the like is less and less, so that research and research on growth of Xingan Lespedeza plants and population structure change rules are mainly carried out on the basis of building a soil coarsening platform, the influence of soil coarsening on plant growth development is deeply analyzed on the individual level and the population level of species, and basic data theoretical support is better provided for the desertification prevention and control scientific research work.
