Problems solved by technology

[0007] River wetlands in arid areas are important types of wetlands in arid areas. Studies have shown that there are few species in this area, and the vegetation communities of various wetland types are deficient in species, with fewer associated species, and most of them are single genera and single species. The community dominance of the community is relatively high, the stability of the vegetation community structure is low, and the ecology is very fragile. Once the dominant species in the community disappear without the replacement of redundant species with similar functions, it will cause serious and irreversible damage to the function of the entire ecosystem. damage
And affected by different hydrological conditions, seed dispersal, and soil conditions, it is difficult to restore vegetation in such wetlands

Embodiment 1

[0033] Example 1 : Collect or prepare wetland vegetation seeds for restoration: collect native species, mainly wetland dominant species seeds in good wetland vegetation areas, collect, process and purify. The main species of river wetlands in arid areas of Xinjiang are Salicornia, Salina, Phragmites, Suaeda salsa, Salicylum, Tamarix, Lycium barbarum, Rush, and Sea Milkweed, etc., which can be used as seeds to restore wetland vegetation.

[0034] Take 10 parts of water by weight, add 3 parts of yellow clay and 0.05 parts of nutrient, the nutrient is formulated into a compound mixture from diammonium phosphate and potassium sulfate at a weight ratio of 1:1, after fully mixing, add Mix 1 part of water-retaining agent evenly to form an adhesive. The water-retaining agent is a water-retaining agent produced by Renqiu Changxing Petrochemical Co., Ltd. The main component is potassium polyacrylate. Add 0.3 parts of the above-mentioned wetland vegetation to 100 parts of adhesive by we...

Embodiment 2

[0036] Example 2 : Take 10 parts of water by weight, add 2 parts of yellow clay, 0.03 parts of nutrient, and 2 parts of water retaining agent, and mix well to form an adhesive. The nutrient is a compound mixture prepared from diammonium phosphate and potassium sulfate at a weight ratio of 1:1.6. The water-retaining agent is a water-retaining agent produced by Guangzhou Yourun Chemical Co., Ltd., and its main component is cross-linked acrylamide / acrylic acid Potassium copolymer. Add 0.5 parts of wetland vegetation seeds to 100 parts of adhesive by weight, mix evenly and apply on the seed paper with a thickness of 1mm, and dry until the two sheets of paper are stacked without sticking. The sub-paper is 40g paper, the size is a rectangle with a side length of 20-30cm, and it is buried according to the best time for the germination of dominant seeds. Choose an area with a relatively flat riverside, a slope of less than 8 degrees, water replenishment conditions or good water con...

Embodiment 3

[0037] Example 3 : Get 10 parts of water by weight, add 5 parts of yellow clay, 0.05 part of nutrient, and 2 parts of water-retaining agent to fully mix and evenly form an adhesive. The nutrient is diammonium phosphate, and the water-retaining agent is polyacrylamide, poly Sodium acrylate copolymer cross-linked product. Add 0.1 part of wetland vegetation seeds to 100 parts of adhesive by weight, mix it evenly, and apply it on 60g of newsprint, with a thickness of 5mm, and let it dry for later use. From the end of February to the beginning of March before spring, choose a river that is relatively flat and has a Areas with good water supplement conditions or good water conditions, poor natural vegetation, and lack of provenance are used as burial areas. The seed paper is arranged in the shape of a character, spread in the burial area at an interval of 40 cm, and covered with 1-2 cm of soil. , and fixed with wood brazing, fixed point 20cm interval.

Abstract

The invention discloses a wetland vegetation protection or restoration and reconstruction method. The method includes: by weight, taking 10 parts of water, adding 2-5 parts of yellow clay, mixing the materials fully, adding 0.5-2 parts of a water retaining agent, mixing them evenly to obtain an adhesive, adding 0.01-0.5 part of a wetland vegetation seed into 100 parts by weight of the adhesive, mixing the materials evenly, then applying the mixture to a seed paper, and performing airing for standby use, selecting a plot suitable for restoration as a burial area, spreading the seed in the burial area, and conducting covering with 1-2cm soil. The method provided by the invention adopts the seed paper as the carrier to conduct wetland vegetation restoration. For arid area wetland plants, the needed provenance can be supplemented and restored artificially, seeds can be fixed at an optimal growth area, thus avoiding drifting of seeds along with water or wind. Especially the restoration time and area are controllable, thus being conducive to creating the best germination conditions for seeds. At the same time, nutrients can be supplemented to provide the basic condition for seed rapid growth. Thus, the protection or restoration and reconstruction effect can be good.

Description

technical field [0001] The invention relates to the field of wetland vegetation restoration, more specifically, to a method for protecting or restoring wetland vegetation in arid areas. Background technique [0002] The seed bank is the sum of all viable seeds present at the soil surface and in the soil. [0003] The study of the seed bank is an important basis for in-depth study of wetland vegetation structure, function and dynamics, and is also an important supplement to the study of wetland biodiversity. instructive. [0004] Some researchers have begun to emphasize the role of seed banks in wetland vegetation restoration. Seed banks provide the possibility for the restoration and reconstruction of damaged plant communities. [0005] First, by studying the composition of the seed bank to determine the species resource reserve of the damaged wetland and judge its self-recovery ability, and provide management strategies for vegetation restoration. [0006] Secondly, many...
