Problems solved by technology

[0003] However, non-woven fabrics will block part of the light, thereby affecting the growth of vegetation. In some practical investigations, the amount of light transmitted under the coverage of non-woven fabrics only accounts for about 63% of atmospheric sunlight; therefore, although covering non-woven fabrics can play a role in moisturizing The positive effect of heat preservation, but it will also bring adverse effects such as reduced light transmission and inhibition of vegetation photosynthesis, especially for vegetation in cold regions with short growing seasons. An important factor in the effect of vegetation regreening, especially in the case of long-term non-woven fabric coverage in the year of regreening sowing, the impact will be more serious, and insufficient early growth will cause serious vegetation degradation in the later stage

Embodiment 1

[0046] A comparison experiment of vegetation restoration was carried out in the disturbed area of ​​the mining area in the same cold area with a short growing season, using the regular removal scheme of green non-woven fabric and the long-term covering method of green non-woven fabric. The vegetation used in the test is a mixture of the main local domesticated grasses Elymus, bluegrass, and Chinese fescue, and the seed dosage is 20g / m 2 , the unit weight of non-woven fabric is 32g / m 2 . Taking the entire growing season in the cold region as an example from June 1 to August 31, sowing and covering with non-woven fabrics (without irrigation) were carried out in late May, and in mid-July (that is, the 1st day of the growing season of suitable herbaceous plants). / 2 hours) Part of the non-woven fabric was removed, and no watering was performed before removal. Preliminary results show that (1) in terms of aboveground biomass per unit area at the end of the 1st year of sowing and ...

Embodiment 2

[0048] A comparison experiment of vegetation restoration was carried out in the disturbed area of ​​the cold mining area with a short growing season, using the regular removal of green non-woven fabric + chlormequat application scheme and the long-term coverage of green non-woven fabric. The vegetation used in the test is a mixture of the main local domesticated grasses Elymus, bluegrass, and Chinese fescue, and the seed dosage is 20g / m 2 , the unit weight of non-woven fabric is 32g / m 2 . Taking the entire growing season in the cold region as an example from June 1 to August 31, sowing and covering with non-woven fabrics (without irrigation) were carried out in late May, and in mid-July (that is, the 1st day of the growing season of suitable herbaceous plants). / 2 hours) part of the non-woven fabric was removed, and no watering was carried out before the removal, and 30 mg / L chlormequat was sprayed immediately after the removal, and the spraying dosage was 1.5 L. Preliminary...

Embodiment 3

[0050] Using white non-woven fabrics for long-term coverage and green non-woven fabrics for long-term coverage, a comparative experiment of vegetation restoration was carried out in the disturbed area of ​​the cold mining area with the same short growing season. The vegetation used in the test is a mixture of the main local domesticated grasses Elymus, bluegrass, and Chinese fescue, and the seed dosage is 20g / m 2 , the unit weight of non-woven fabric is 32g / m 2 . Taking the entire growing season in the cold region as an example from June 1 to August 31, sowing and covering with non-woven fabrics (without irrigation) were carried out in late May, and in mid-July (that is, the 1st day of the growing season of suitable herbaceous plants). / 2 hours) Part of the non-woven fabric was removed, and no watering was performed before removal. Preliminary results show that (1) the aboveground biomass per unit area at the end of the first year of regreening after sowing, the long-term co...

Abstract

The invention provides a herbaceous vegetation regreening method. The herbaceous vegetation regreening method comprises the steps that S1, selecting local suitable herbaceous plants for sowing; S2, covering the sowing area with a non-woven fabric; and S3, determining the length of the growing season of the local suitable herbaceous plants, removing the covered non-woven fabric at 2 / 5-2 / 3 of the growing season of the suitable herbaceous plants, and irrigating the planted suitable herbaceous plants 1-5 days before the covered non-woven fabric is removed. The non-woven fabric covering the suitable herbaceous plants is removed at 2 / 5-2 / 3 of the growing season of the suitable herbaceous plants, so that better photosynthesis conditions can be provided for the whole-cycle growth of the regreening plants in the first year, the growth of the plants (especially the growth of underground root systems) can be promoted, the biomass and self stress resistance of the regreening plants can be improved, so that the survival rate is increased, and the ecological stability is enhanced.

Description

technical field [0001] The invention relates to the technical field of ecological greening, in particular to a method for regreening herbaceous vegetation in disturbed areas in cold regions with short growing seasons. Background technique [0002] Vegetation growth in cold regions with a short growing season is affected by low temperature, low oxygen, and short growth periods. It is very difficult to restore the damaged ecological vegetation after disturbance. Vegetation regreening (including restoration of naturally degraded vegetation in cold regions) in cold regions disturbed by activities such as mining and road construction, mostly adopts the method of grass seed sowing + non-woven fabric long-term coverage. [0003] However, non-woven fabrics will block part of the light, thereby affecting the growth of vegetation. In some practical investigations, the amount of light transmitted under the coverage of non-woven fabrics only accounts for about 63% of atmospheric sunligh...
