Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The embodiment provides a method for regreening herbaceous vegetation, which is mainly suitable for cold regions and disturbed regions with short growing seasons, wherein the cold regions with short growing seasons refer to high-latitude and high-altitude climate cold regions with the duration from green turning to withering and yellow being within 4 months. The disturbance area comprises a mining exploitation area, a traffic construction area and the like. The environment in these areas is relatively harsh and presents a number of disadvantages for the growth of vegetation. Therefore, the embodiment provides a method for regreening herbaceous vegetation, so as to improve the current-year survival rate and biomass of regreening herbaceous plants in a cold region disturbance area with short growing season, the green returning rate and the tiller percentage in the next year, and improve the regreening engineering effect in the cold region regreening area; the long-term natural propagation growth of the greening vegetation in the cold area disturbance area is realized, so that the greening engineering of the vegetation in the cold area is long-lasting.
Referring to fig. 1, the method for re-greening the herbaceous vegetation of this embodiment includes:
s1, selecting proper herbaceous plants for sowing; herein, the properly growing herbaceous plant means herbaceous plants properly growing, and thus, the herbaceous plant selected may be different for different regions.
S2, covering the sowed area with non-woven fabrics; the non-woven fabric is laid, so that the heat preservation and moisture preservation effects on the planted herbaceous plants can be achieved, and the germination rate and the survival rate are improved.
S3, determining the proper growing season length of the proper herbaceous plant, uncovering the covered non-woven fabric when 2/5-2/3 of the growing season of the proper herbaceous plant, and irrigating the planted proper herbaceous plant 1-5 days before uncovering the covered non-woven fabric.
In one embodiment, the planted grassy plants can be irrigated 2-3 days before the non-woven fabrics are uncovered, and the irrigation before the non-woven fabrics are uncovered can ensure the soil humidity of the grassy plants, so that the problem that the growth of the grassy plants is unstable due to the rapid reduction of the soil humidity after the non-woven fabrics are uncovered is solved.
Because the non-woven fabrics that lay exist can not complete printing opacity problem, consequently after the herbaceous plant grows up, the light that receives certain influence to can cause the influence to the growth of herbaceous plant, can influence the normal photosynthesis process of the compound green plant (promptly to the growth that has the suppression effect to the compound green plant in the non-woven fabrics coverage cycle). The inventor finds that the effect of the non-woven fabric covering on the growth of the herbaceous vegetation is small for the herbaceous vegetation in the non-cold area, but the effect on the growth of the herbaceous vegetation in the cold area and the disturbed area with short growing season is large, so the embodiment adopts the scheme of uncovering the laid non-woven fabric in the growing season of the proper herbaceous plant (namely, the non-woven fabric uncovering scheme periodically), on one hand, the non-woven fabric can play a role in improving the germination rate and the survival rate in the early stage, and the role in the later stage of the herbaceous plant growth is gradually reduced, so the problem of photosynthesis inhibition caused by the non-woven fabric can be reduced after the laid non-woven fabric is uncovered in the growing season of the proper herbaceous plant. Therefore, the herbaceous plants in the current year grow more vigorously and the root systems are developed, and the full growth of the underground root systems in the early stage has important influence on the growth stability in the later stage (the next year).
The time for removing the non-woven fabric is selected to remove the covered non-woven fabric when 2/5-2/3 of the growing season of the proper herbaceous plant is carried out, the requirements of the growth of the proper herbaceous plant on heat preservation and moisture preservation are large before 2/5 of the growing season of the proper herbaceous plant, if the non-woven fabric is removed, a certain amount of the proper herbaceous plant can die, and after 2/3 of the growing season of the proper herbaceous plant, the annual growth of the proper herbaceous plant enters the later stage, the sufficient photosynthesis growth time is limited, and the accumulation of the biomass and nutrients of the proper herbaceous plant is not facilitated.
In summary, the non-woven fabric covered by the method is uncovered when 2/5-2/3 of the growing season of the suitable herbaceous plant is selected, so that the growing condition of the suitable herbaceous plant is obviously improved, the root growth state and the vigorous degree of the suitable herbaceous plant are greatly improved, the survival rate and the biomass of the suitable herbaceous plant in the current year and the green returning rate and the sprouting rate of the suitable herbaceous plant in the next year are improved, the long-term natural propagation growth of the re-green vegetation in the cold region disturbance area is realized, the re-green engineering of the cold region vegetation is long-lasting, and the re-green engineering effect of the cold region re-green area is improved.
In one embodiment, in the S1, the seeding amount is 10g/m2The above; the selected seeds are wild plant seeds and seeds obtained by artificial breeding and seed production of wild plants. The time of sowing should be selected after the soil on the local surface is thawed, and the time should be too early.
In one embodiment, the selected seeds are a mixture of acclimatized grass elymus pratense seeds, Poa annua seeds and Festuca arundinacea seeds.
In one embodiment, the non-woven fabric is green non-woven fabric and is made of degradable pollution-free materials; the weight per unit area of the non-woven fabric is 15-40g/m2. The drier and cold regions have larger unit area weight of the non-woven fabric, thereby improving the heat preservation effect and the moisture preservation effect.
Wherein, the green non-woven fabric cover can form the early green landscape effect while playing the role of heat preservation and soil moisture preservation; the non-woven fabric is prepared from degradable materials.
The non-woven fabric which is torn off after short-term covering use can be recycled for secondary use, thereby reducing the comprehensive cost, and realizing the resource saving and environmental protection.
In one embodiment, the non-woven fabric is green non-woven fabric or white non-woven fabric and is made of degradable pollution-free materials. The white non-woven fabric is selected to improve the light transmittance, so that the photosynthesis effect of the grassy plants is improved.
In one embodiment, after the non-woven fabric is covered and before the proper grass plants germinate, the planted proper grass plants are irrigated to improve the germination rate of the proper grass plants and ensure that the proper grass plants have good growing environment in the early stage.
In one embodiment, referring to fig. 2, after the S3, the method further includes: and S4, spraying the dwarf regulator on the grassy plants within 7 days after the non-woven fabrics covered by the non-woven fabrics are uncovered. By spraying the dwarf regulator, the growth of plants (particularly the growth of underground roots) is facilitated, the stress resistance of the greening plants is improved, the survival rate is further improved, and the ecological stability is enhanced. This example is a non-woven fabric periodically uncovered plus chlormequat chloride application protocol.
In one embodiment, the chlormequat modulator is comprised of chlormequat chloride or paclobutrazol; the concentration of the regulator is 20-50mg/L, and the dosage is 1-2L/m2。
For example, the concentration of the short-stature regulator can be 30-40mg/L, and the dosage is 1.5-2L/m2。
In one embodiment, in the S3, the covered non-woven fabric is uncovered at 1/2-3/5 of the growing season of the grassy plant.
In order to verify the technical effect of the technical solution in this embodiment, the present embodiment provides the following examples.
