Sandy soil greening construction method

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-...

Problems solved by technology

The windproof and sand-fixing greening planting method disclosed in this patent document can play a certain windproof effect by setting up multiple belt-shaped sand barriers in the mobile sand dune zone, but the windproof ability of the belt-shaped sand barriers is limited, and it is easy to be eroded by strong winds. Fundamentally, the sand is fixed, and the shrub seedlings planted at the position where the belt-shaped sand barrier is located will easily lose water during the irrigation process, and the water retention effect is poor, which cannot effectively prevent sandy desertification.
