Abstract

The invention discloses a sandy soil greening construction method, and belongs to the environment protection engineering technical field; the method comprises the following steps: preparing a curing agent; mixing the curing agent with sandy soil so as to form curing sand; digging deep pits and shallow trenches in the sandy soil, drilling water funnels into the deep pits, filling the curing sand into the deep pits and shallow trenches, planting saplings into the deep pits, allowing sapling roots to extend to the water funnel mouths, and spreading grass seeds in the deep pits and shallow trenches; laying fine sands on the grass seeds, using a mulch film to cover the grass seeds, opening vents on the mulch film, inserting wooden slots around the mulch film, and pouring slurry into the slots so as to form a water fence; watering the grass seeds for maintenance, and irrigating in every 1-2 days until the grass seeds germinate. The method mixes the curing agent with the sandy soil so as to fill inner gaps of the soil particles; the curing sand particles cannot easily disperse and jump, thus contentiously providing sufficient water for plants, and realizing long term windproof, sand solidification, water retention and greening effects.

Description

technical field

[0001] The invention relates to the technical field of environmental protection engineering, in particular to a sandy soil greening construction method suitable for desert areas. Background technique

[0002] Land desertification is an ecological environment problem caused by land degradation caused by human activities. China is one of the countries most seriously affected by desertification. In 1999, the area of ​​desertified land in my country reached 267.4 square kilometers, accounting for 27.9% of the total land area of ​​the country. %, and is still expanding at a rate of 3140 square kilometers every year. Among them, the area of ​​wind-eroded desertification is 187.3 square kilometers, accounting for 70% of the total desertified land area, manifested as desertification of farmland and grassland, mainly located in the arid and semi-arid areas of Northwest China, such as Inner Mongolia, Xinjiang, Gansu, Ningxia, and northern Shaanxi. In the arid and semi-...

Examples

Embodiment 1

[0038] A sandy soil greening construction method, comprising the following steps:

[0039] a, sodium carboxymethyl cellulose, anionic polyacrylamide, ferrous chloride and water are configured as a curing agent;

[0040] b. Mix the curing agent with sand to form solidified sand, pile the solidified sand on the ground with plastic cloth, and cover the surface of the solidified sand with plastic cloth;

[0041] c. Dig out deep pits for planting trees and shallow ditches for planting grass in the sand. The length and width of the deep pits are greater than 30cm, and the depth of the deep pits is 20cm. The width of the shallow ditch is the same as the width of the deep pit, and the depth of the shallow ditch 15cm, a piston is detachably connected to the water collection funnel, drill the water collection funnel into the deep pit, and then fill the solidified sand into the deep pit and shallow ditch, and the solidified sand will form a deep pit in the deep pit to fix sand and absorb...
