Description
Technical Field
The invention relates to the field of ecological environment protection, in particular to a method for treating Hulebel desertification sandy grassland by utilizing grass-irrigation planting bags.
Background
The Hulun Bei Ersha is positioned in the abdominal region of the Hulunebel grassland and is composed of three sand belts, the length of the sand belt at the north part is about 110 km, the width of the sand belt at the width is 6-30 km, and most of the sand belts except for the Saurus at the north part are distributed on the North shore of the sea, and the sand belts are distributed on the south shore of the sea; the sand belts in the middle are distributed along the first line of the Azuki Gu Langzhen and the Huihe sappan at the edge of the Gan Zhuer temple northwest marsh, the sand belts are about 100 percent km in length and about 5 to 18 percent km in width and are distributed along the Huihe ancient river channel in an L shape; the south sand belt is about 50 km a long and about 10a km a wide, the southeast st Yimin river upstream head road bridge, the northwest to the edge of the swamp near Gan Zhuer a. The three sand strips are distributed approximately along the sea-Layer river-like ground and the river-like ground and are in east-west trend, and mainly comprise fixed semi-fixed crescent sand dunes and honeycomb sand dunes. Besides the three sand holes, the downstream coastal areas in the Imine river, the Wu Erxun river east coast, the Hulun lake east coast, the southwest coast, the sea Laer west mountain and other lands also have sporadic sand hill distribution, and most of the sand hills are single crescent sand hills which are semi-fixed or flowing.
The sargassy grassland in the Hulebel region is characterized in that: the sand is between flowing and semi-fixed, and a small amount of vegetation is mainly caragana microphylla and Huang Liuhe-degree artemisia rupestris, and the vegetation accounts for less than 5%. The sand dunes are carried by wind to form sand dunes with the height of 20-30 m, and wind erosion pits are arranged between the dunes. Due to the action of wind, the dune is continuously enlarged from the air inlet to the air outlet. Without artificial action (grazing), sandy grass areas also have difficulty in forming stable vegetation in a natural state, making sand difficult to control. Under the conditions of grazing and drought, the sand dunes are blown by wind to form new terrain expansion, and the area is large and the speed is high. Because of long-term tuyere transport, the surface fine sand is blown away, leaving large-particle sand, which is difficult to plant, and a manual mode needs to be found for control.

Sowing according to rows, wherein the row spacing is 50cm. Combination 1: the mass ratio of the leymus chinensis, the elytrigia repens, the herba Medicaginis, the common sage herb and the oat is 1.2:1.0:0.3:0.3:0.2. Combination 2: the mass ratio of the leymus chinensis domesticated according to the method of the example 1 to the elytrigia repens domesticated according to the method of the example 1 to the herba Medicaginis, the herba Medicaginis is moistened according to the method of the example 1 to the herba Artemisiae Annuae domesticated according to the method of the example 1 to the oat domesticated according to the method of the example 1 is 1.2:1.0:0.3:0.3:0.2. Other treatment methods of the test plots of combination 1 and the test plots of combination 2 were the same and were all treated as in example 1.
The test plots were sown at day 15 of year 2021. 2021. The test plots were continuously investigated and counted in 2022 and 2023, 8 months. Vegetation investigation: the vegetation types, coverage, density and height in the sample party are investigated on the spot every month.
2. Test results
1. Vegetation type change condition
The combined 1-planting-bag test plot is planted for 2-3 years, no new plant invades on the basis of original plants, and only a small amount of leymus chinensis survives in the third year of planting, so that the non-domesticated grass seeds cannot adapt to the soil quality and environment of the test plot.
After 2-3 years of planting, the combined 2-planting-bag test plots gradually invade annual plants, such as the worm, the thorns and the chenopodium, the number of the plant seeds of the test plots is increased, the diversity of the plants is increased, the domesticated grass seeds can be well adapted to the soil and the environment of the test plot, and the microenvironment of the test plots can be gradually improved.
2. Vegetation height, coverage and density variation
The data collected by the test plots of the 1 planting bags are processed and analyzed, the average height of the samples is 14cm, the average coverage is 18.7%, the average density is 31.6 plants/m 2 after 3 years of restoration, and the restoration effect is extremely poor.
The data collected by combining 2 planting bag test plots are processed and analyzed, the average height of samples is 38cm, the average coverage is 78.4%, the average density is 142.3 plants/m 2, and the repairing effect reaches the expected effect after 3 years of repairing. The combined 2 planting bag test plots are obviously higher than the combined 1 planting bag test plots in terms of height, coverage and density, so that the domesticated grass seeds have good adaptability and can quickly recover sandy grassland vegetation.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
