Embodiment 1

[0025] Test site selection:

[0026] Ganglong Village, Ganglong Town, Gande County, Guoluo Tibetan Autonomous Prefecture, located in the source area of ​​the Three Rivers, is selected. The geographical location is 34°27′N, 100°12′E, and the average altitude is 3760m. Climate zone: The annual average temperature is -1.8°C, the average annual precipitation is 539.3 mm, the annual sunshine hours are 2453 hours, the annual average precipitation is 520 mm, the pasture growth period is 112 days, and there is no absolute frost-free period. The soil is alpine meadow soil. The sample plot is a black soil beach type poisonous weed grassland, the main species are grasses mainly including Elymus tachycarpa and Poa crymophila, and sedges mainly including Kobresia humilis. Grasses, as well as forbs such as Qinghai japonicus (Morina kokonorica Hao), yellow broom (Ligulariavirgaurea), and Densa benth (Elsholtzia densa Benth).

Abstract

The invention discloses a method for treating a black soil beach, which comprises the following steps: leveling a land, applying a base fertilizer, digging pits, selecting annual rheum tanguticum seedlings and elymus nutans seeds, transplanting the rheum tanguticum seedlings after the soil is unfrozen in spring every year, and planting one seedling in each pit. After the transplanting of the rheum tanguticum is completed, sowing elymus nutans seeds in the middle of the line spacing of the transplanting pits of the rheum tanguticum according to the sowing rate of 3kg/mu. Finally, urea is applied twice in July and August respectively. According to the method, the rheum tanguticum and the elymus nutans are intercropped, the rheum tanguticum in a simulated wild environment is used as an associated species to form a stable community with the alpine grassland, a deep root system is matched with a shallow root system, broad-leaved plants and gramineous plants are intercropped, community diversity can be increased, resources can be fully utilized, and grazing tolerance is good; and the problem of secondary degradation of the black soil beach is effectively solved. Through the intercropping of the herbs, the vegetation coverage of a planting area and the overground biomass are also greatly increased, so that the purpose of preventing and treating rodent damage is achieved.

Description

technical field [0001] The invention belongs to the technical field of grassland ecology, and discloses a method for controlling black soil beaches, in particular a method for controlling black soil beaches by intercropping rhubarb tangut and Elymus chinensis interplanting. Background technique [0002] The Sanjiangyuan area has an important function of water conservation, is a key area for national ecological function protection, and is also a concentrated distribution area of ​​alpine grassland. However, due to the sensitivity and fragility of the ecological environment of the alpine grassland, coupled with the impact of climate change and human activities in recent years, it has caused extremely serious grassland degradation, and a large area of ​​secondary bare land - "black soil beach" has appeared. [0003] In order to effectively curb the harm and continuous expansion of "black soil beaches", the state has implemented a series of ecological restoration projects in the...
