Embodiment 1

[0020] From August to September in autumn, harvest the stalks of the stalks with ripe fruit and dry plants, and there is no requirement for the stalk size of the stalks;

[0021] Stir 150 g of a commercially available water-retaining agent (its main component is: starch-grafted acrylate copolymerized cross-linked product) into 30 liters of water to prepare a solution with a concentration of 0.5%, stir for 20 minutes, and put 500 strains of dry pigtail into Soak in the solution for 30 seconds;

[0022] Dig a pit at a distance of 100 cm from the edge of the Populus euphratica forest. The depth of the pit is 80 cm, and the length and width are 100 cm. The soaked pig hairy vegetables are tiled at the bottom of the pit with a thickness of 10 cm, and then the excavated soil is filled back and compacted;

[0023] After it is confirmed that the pig hairy vegetables are buried, use an earth drill to drill 4 ventilation holes evenly on the surface of the pit, and the depth of the ventil...

Embodiment 2

[0025] From August to September in autumn, harvest the stalks of the stalks with ripe fruit and dry plants, and there is no requirement for the stalk size of the stalks;

[0026] Stir 300 g of water-retaining agent (its main component is: starch-grafted acrylate copolymer cross-linked product) into 30 liters of water, stir for 20 minutes, prepare a solution with a concentration of 1%, and soak 1,000 dried pigtails for 10 minutes ;

[0027] Digging a pit at distance 250cm from the edge of the Populus euphratica forest, the depth of the pit is 90cm, and the length and width are each 150cm. In the pit, the pre-treated pig hairy vegetables are laid flat, and the thickness is 10cm. Fill back the excavated soil and compact it;

[0028] After it is confirmed that the pig hairy vegetables are buried, use an earth drill to drill 4 ventilation holes evenly on the surface of the pit, and the depth of the ventilation holes should be 75cm.

Embodiment 3

[0030] From August to September in autumn, harvest the stalks of the stalks with ripe fruit and dry plants, and there is no requirement for the stalk size of the stalks;

[0031] Stir 200 g of the water-retaining agent (its main component is: starch-grafted acrylate copolymerized cross-linked product) into 30 liters of water, stir for 20 minutes, prepare a solution with a concentration of 0.8%, and soak 800 strains of dried pigtails for 8 minutes ;

[0032] Digging a pit at distance 150cm from the edge of the Populus euphratica forest, the depth of the pit is 100cm, and the length and width are each 100cm. In the pit, the pre-treated pig hairy vegetables are tiled, and the thickness is 10cm. Fill back the excavated soil and compact it;

[0033] After it is confirmed that the pig hairy vegetables are buried, use an earth drill to drill 4 ventilation holes evenly on the surface of the pit, and the depth of the ventilation holes should be 90cm.

Abstract

The invention relates to a rapid method for improving carbon sequestration of soil in an arid desert area, which includes: according to soil temperature, soil properties and carbon sequestrating mechanism of the arid area, effectively using salsola collina, field weed, and directly and manually fixing surface organic carbon portions of salsola collina into the soil; and allowing plants of salsola collina to decompose to improve soil environment for growth of root systems of populus euphratica and quicken development of the root systems of populus euphratica, and accordingly increasing organic carbon in subsoil to compensate loss that severe decline of populus euphratica forest due to great decrease of underground water level of the arid desert area causes decrease of carbon sequestration of the ecological system.

Description

technical field [0001] The invention relates to a method for improving soil carbon sequestration capacity in arid desert areas, in particular to a rapid method for improving soil carbon sequestration capacity under Populus euphratica forests in arid desert areas. Background technique [0002] At present, the area of ​​arid and semi-arid areas in the world has exceeded 1 / 3 of the total land surface area of ​​the earth. Due to harsh climatic conditions and increasing population pressure, problems such as desertification in these areas are becoming more and more serious. Land desertification affects about 3.6 billion hectares of land worldwide. my country's desertified land accounts for about 27.2% of the country's land area, and it is one of the countries most seriously affected by desertification in the world. The special ecological conditions and natural environment in the arid desert area lead to generally low soil organic matter content, phosphorus and nitrogen deficienc...
