Embodiment 1

[0057] Embodiment 1: Mixed sowing experiment of Elymus chinensis and dicotyledonous plants.

[0058] The experiment has three seeding treatments:

[0059] The first treatment only sowed the monocotyledonous plant Elymus, M;

[0060] The second treatment is to mix the monocotyledonous Elymus chinensis and three dicotyledonous plants, namely Aconitum aconitum, Dandelion, and Artemisia gansuensis, M+3D;

[0061] The third treatment is to mix the monocotyledonous plant Elymus chinensis and 8 kinds of dicotyledonous plants, namely Aconitum aconitum, Dandelion, Artemisia gansuensis, Artemisia spp. Vegetables, Gentian acupoints, M+8D.

[0062] Each treatment plot was 12 square meters X 5 replicates, and the same seeding density was maintained. The total sowing density is 1200 grains / 12 square meters, the sowing density of each dicotyledonous plant in M+3D is 400 grains / 12 square meters, and the sowing density of each dicotyledonous plant in M+8D is 150 grains / 12 square meters.

Embodiment 2

[0072] Embodiment 2 discloses a kind of sowing device used in the above sowing method, the following in conjunction with the attached Figure 6-16 Describe it in detail.

[0073] Reference attached Image 6 And attached Figure 7 , the sowing device includes a frame assembly 1 connected with a tractor, and its frame assembly 1 includes an upper carrier plate 100 and a number of ground-running wheels 101 arranged on the lower surface of the upper carrier plate 100, and at the same time, the upper carrier plate 100 is far away from the ground for reclamation. One end of the mechanism 200 is provided with two latch holes 102, and each latch hole 102 is provided with a latch rod for connecting with a tractor. By connecting the frame assembly 1 with the tractor, the whole sowing device can be driven by the tractor.

[0074] This sowing device is also successively provided with a soil-breaking reclamation mechanism 200, a ditch assembly 700, a quantitative sowing mechanism 300, a...

Abstract

The invention relates to the technical field of degraded grassland recovery, and particularly discloses a sowing method for promoting stable recovery of Qinghai-Tibet plateau vegetation and a sowing device. The method comprises the following steps: (1) preparing a plurality of seeds of elymus nutans, aconitum gymnandrum, dandelion, pedicularis przewalskii, pedicularis semitorta, picris hieracioides, potentilla potaninii, potentilla fragarioides and gentianella acuta, placing the seeds in a constant-temperature refrigerator for refrigeration treatment for a period of time; (2) sowing at the beginning of a growing season, removing sundries on the ground before sowing, and turning over the ground for reclamation; (3) sowing the seeds in a sowing mode that the dicotyledonous plant sowing density is 140-160 seed /12 square meters and the total sowing density is 1100-1300 seed /12 square meters, and then covering thin soil with the seeds; and (4) flatting the ground. Compared with the single planting of elymus nutans, the whole sowing method provided by the invention has the advantages that the monocotyledonous elymus nutans is matched with the dicotyledonous mixed sowing mode, the community stability is higher, and the diversity of animals and plants is higher.

Description

technical field [0001] The invention relates to the technical field of restoration of degraded grassland, and specifically discloses a sowing method and a sowing device for promoting the stable restoration of vegetation on the Qinghai-Tibet Plateau. Background technique [0002] For the degradation of alpine meadows on the Qinghai-Tibet Plateau, natural restoration methods are generally adopted as the main method, supplemented by artificial intervention methods to promote its restoration. The former, such as confinement and grazing restriction (CN201310600869.5), has a small input cost and stable restoration effect, but generally takes a long time, and is not suitable for the rapid restoration of degraded meadows; The input cost is high and the effect is quick, but the recovery effect is unstable, and it is often necessary to replant and supplement fertilizer several times; specifically, because of the inability to establish a stable connection with the regional environment ...
