Embodiment Construction

[0017] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0018] 10 days before the arrival of the rainy season, mix 7.5kg of wild oat seeds and 3kg of Elymus chinensis seeds per mu, and use a no-tillage seeder to directly re-sow on the degraded grassland with no-tillage. After sowing, it just catches up with the rainy season to facilitate emergence , Usually 15 days after sowing, the seedlings can emerge one after another. All seedlings emerged within 30 days after sowing, and the total emergence rate was about 30%. With the increase of rainfall in the rainy season, the plants grow faster, and the plant height can reach 50-90cm. Among them, the plant height of Elymus is about 15cm, and the plant height of oats is 50-90cm. The vegetation coverage of the re-seeding plot can reach more than 80% . Some wild oats can reproduce a certain amount of seeds in one year, about 15-20kg / mu, and can produ...

Abstract

The invention discloses a method for restoring severely-degraded grassland vegetation in Tibet by using dormant oats. The method comprises the following steps: before 10 days of rainy season, wild oat seeds are uniformly mixed with elymus dahuricus seeds in each mu; no-tillage direct reseeding is carried out on degraded grassland by using a no-tillage planter, wherein along with increase of rainfall in the rainy season, the heights of plants can reach 50 to 90cm, and the vegetation coverage of an annual reseeding plot reaches 80 percent or above; part of wild oats can reproduce a certain amount of seeds in the same year, and can produce not lower than 30g of wild oat seeds in the second year, and subsequently, the yield of the wild oat seeds can be stabilized at 40kg per mu; by using dormancy, mobility and seed holding property of the wild oats, the wild oat seeds which are newly produced on the plot all enter soil; wild oat seeds reproduced by the plot in the second year and the later year further enter the soil, and further emerge, grow and reproduce new wild oat seeds. According to the method disclosed by the invention, restoration and rebuilding of the degraded grassland can be ensured.

Description

technical field [0001] The invention belongs to the technical field of agriculture and animal husbandry, and relates to a method for restoring severely degraded grassland vegetation in Tibet by using dormant oats. Background technique [0002] Wild oats are usually vicious weeds in agricultural areas. Part of the seeds (50%) scattered into the soil cannot emerge immediately even if conditions such as temperature and humidity are suitable. Some seeds even emerge after 5 years. This is the dormancy of wild oat seeds . [0003] Tibet's natural grasslands are located at high altitudes (above 4200m), cold (annual average temperature below 5 degrees Celsius), drought (annual average precipitation is less than 300mm), strong winds (132 days of strong winds, average wind speed 5m / s), and plant growth period of 60 -90 days. The wind erosion and water erosion caused by grassland degradation are extremely serious, and the impact caused by wind erosion is the most serious due to the l...
