Problems solved by technology

This method of first two sides and then the middle can finally make the sand barrier into a whole, but the carex planted in the first stage will also be eroded by natural wind during the process of wind erosion of sand dunes, resulting in a very low survival (preservation) rate of vegetation, which is difficult to meet expectations Effect
[0006] At present, the solutions to the problems of low plant survival rate, weakened ecological function, low efficiency of large-scale restoration, and difficult industrial construction operations encountered in the control of grassland desertification in alpine areas are still insufficient.

Embodiment 1

[0047] Example 1 as Figure 1~3 As shown, an ecological modular alpine meadow restoration method includes the following steps:

[0048] ⑴Break the thick stalks of crop stalks such as wheat, corn, and potatoes into small pieces with a side length of 0.5-1.5 cm, and cut the thin stalks into small pieces of 6-8 cm. The mass ratio of 2:3 is mixed to obtain the treated crop straw.

[0049] ⑵Mix the harmless treated animal and plant waste and clay evenly at a mass ratio of 1:2 to obtain a soil and fertilizer mixture.

[0050] (3) Evenly blending the treated crop stalks with the soil and fertilizer mixture, then adding water and stirring to obtain a mixture with a slump of 10-20 mm.

[0051] Wherein: the added amount of the treated crop straw is 4-5% of the weight of the mixture; the added amount of the soil fertilizer mixture is 90-92% of the weight of the mixture.

[0052] (4) The mixture is filled into a 5-hole polygonal mechanized mold for pressing, and placed in a ventilated ...

Embodiment 2

[0059] Example 2 as Figure 4 As shown, an ecological modular alpine meadow restoration method includes the following steps:

[0060] ⑴Break the thick stalks of crop stalks such as wheat, corn, and potatoes into small pieces with a side length of 0.5-1.5 cm, and cut the thin stalks into small pieces of 6-8 cm. The mass ratio of 1:1 is mixed to obtain the treated crop straw.

[0061] ⑵Mix the harmless treated animal and plant waste and clay evenly at a mass ratio of 1:2 to obtain a soil and fertilizer mixture.

[0062] (3) After uniformly blending the treated crop stalks and soil fertilizer mixture, add water and stir to obtain a mixture with a slump of 10-20 mm.

[0063] Wherein: the added amount of the treated crop straw is 5-6% of the weight of the mixture; the added amount of the soil fertilizer mixture is 88-91% of the weight of the mixture.

[0064] (4) Fill the mixture into a 3-hole I-shaped mechanized mold for pressing, and place it in a ventilated place to dry natur...

Abstract

The invention relates to a restoration method for ecological modularized alpine meadows. The restoration method comprises the following steps: (1) a thick-stem diameter part of crop straw is smashed into small pieces, and a thin-stem diameter part is cut into small pieces, and mixing is performed to obtain treated crop straw; (2) animal and plant waste harmlessly treated and clay are evenly mixedto obtain a clay fertilizer blend; (3) after the treated crop straw and the clay fertilizer blend are evenly mixed, water is added for stirring to obtain a mixture; (4) the mixture is compacted and naturally air-dried to prepare 5-hole polygonal ecological modules or 3-hole I-shaped ecological modules with connecting parts; (5) grass seeds are planted in the ecological modules, and are cultivatedto a budding stage to obtain cultivated ecological modules; and (6) after the monsoon season ends and before the rainy season comes, the cultivated ecological modules are paved on sandy grassland, andthe modules are connected by the connecting parts to form a restored region. The restoration method has the characteristics that the plant survival rate is high, the restoration efficiency is high and industrialized construction operation is facilitated.

Description

technical field [0001] The invention relates to the field of grassland desertification control in alpine regions, in particular to an ecological modular alpine meadow restoration method. Background technique [0002] As an irreplaceable part of the ecosystem of the Qinghai-Tibet Plateau, the Maqu Grassland not only has important functions of biodiversity protection, soil protection, and desertification control, but also is the most important runoff-producing area in the upper reaches of the Yellow River, a water source conservation area, and an important resource for the entire Yellow River basin. The water supply area, known as the "Chinese Water Tower" and "The World's Yellow River Reservoir", is a huge ecological barrier in the upper reaches of the Yellow River. However, this area is a typical area with fragile ecological environment. Under the background of global warming, especially under the increasingly frequent interference and damage of human activities, the vegetat...
