Description
Technical Field
The invention belongs to the technical field of plant propagation; in particular to a method for determining the propagation and updating of desert plant red sand under different types of land.
Background
The red sand (Reamuria songaria) is red sand of Tamaricaceae, belongs to super-arid shrubs, has the characteristics of drought resistance, cold resistance, saline-alkali resistance, barren resistance, long service life and the like, and is one of the zonal vegetations with the widest distribution range and the largest ecological amplitude in temperate zone desert areas and desert grassland areas in China. As a good sand-fixing plant in desert regions, the ecological sand-fixing plant plays a role of an ecological barrier in the aspects of fixing quicksand, maintaining the balance of desert ecosystem and the like. Meanwhile, the feed plant is an important feed plant for desert grasslands. The total salt content in the red sand leaves is 27.91% on average, the appetite of cattle and sheep is good, the appetite of livestock can be improved, and the fat increase of livestock can be promoted. According to related reports, the fresh biomass of the red sand contains higher crude protein and crude fat, the red sand also has medicinal value, and the tender branches and leaves of the red sand are used for treating eczema and dermatitis and can also be used for clearing away heat and sweating.
Red sand is one of important desert vegetation in dry areas downstream of the sheep's river. After the 80 s in the 20 th century, a large-area artificially constructed arbor forest in the civil logistics downstream of the sheep river begins to have bitter tips and even decay, sandy shrubs gradually become main vegetation in a desert ecosystem, and red sand is taken as typical desert vegetation and shows a gradually increasing trend. However, at present, researches on the capability of natural propagation and updating of seeds of red sand under different conditions of the land are less, and the updating speed under different conditions of the land, the seedling emergence amount of the seeds, the preservation amount of the seedlings, the growth condition of stock plants, the density of the stock plants in unit area and the like are lacked, so that the natural updating rule of the red sand under different types of the land at the downstream of the sheep-stone river is researched, the natural characteristics of the red sand are further mastered, and an important reference value is provided for artificial promotion and updating in a drought desert area in future. Accelerating the artificial promotion and recovery process of the red sand population in the arid region.
