Embodiment 1

[0036] The specific implementation site of the present invention is located in the heavily degraded grassland in the east of Duerbert Mengtaraha Town, Daqing City, Heilongjiang Province, with a geographical location of N45°53'~47°08', E123°45'~124°42', and an average altitude of 152m, it belongs to the temperate continental monsoon climate, there are many sandstorms in spring, and the precipitation is small. The average annual precipitation is about 400mm, most of which are concentrated in July-September. The number of days is 210 days, the frost-free period is 140 days, the freezing period is in early November, and the thawing period is in early May. The soil type is mainly meadow soil. The pH value of saline-alkali bare land is 10.0-10.6, and the soil moisture content is 8.0-15.0%. The vegetation in the plot is a typical degraded grassland, with an average plant height of 20cm, a total coverage of -2 , the main distribution is Carex duriuscula (Carex duriuscula) with a heig...

Abstract

The invention relates to the field of ecological engineering and in particular relates to a method for rapidly planting vegetation in saline-alkali bare land. The method comprises the steps of harrowing, building a furrow, taking aeolian sandy soil or farmland soil, mixing the aeolian sandy soil with saline-alkali soil, then mixing with seeds of perennial plants, dibbling the seeds into the furrow, and then covering, and finally carrying out pulled-type rolling. The method disclosed by the invention provides a safe site for seed germination, seedling settlement, growth and propagation of the perennial plants, and the perennial plants can quickly grow on the saline-alkali bare land in salinized and alkalized grassland. Thus, the method disclosed by the invention can rapidly increase covering power of vegetation on the grassland, reduce harm of wind erosion and water erosion in the saline-alkali bare land to adjacent grassland and farmland and protect and improve ecological environment; meanwhile, a large area of saline-alkali bare land can be utilized, high-quality forage grass is provided for development of animal husbandry, and higher ecological, economic and social benefits are produced. The method disclosed by the invention has the advantages that operation is easy, efficiency is high, cost is low, is sustainable and easy to popularize, and the like.

Description

technical field [0001] The invention relates to the field of ecological engineering, in particular to a method for quickly establishing vegetation on saline-alkali bare land. Background technique [0002] The physical and chemical properties of saline-alkali bare soil are poor, such as high soil salinity content and pH value, low nutrient content and soil effective moisture, compact soil texture, hard topsoil crust, etc.; the soil seed bank has a single variety of seeds, The number is rare, and most of them are seeds of annual plants, and there are few or no propagules of other perennial plants. Even in the rainy season, when the soil moisture content is high and the salinity of the surface soil is slightly reduced, some plant seeds can germinate, but in the dry season, the plant seedlings wither and die due to the low soil water potential. Therefore, the poor physical and chemical properties of the saline-alkali bare soil, the scarcity of seed sources and the difficulty of...
