Abstract

The invention provides a sand fixation cultivation medium for wind-drift sand in a high attitude area and a using method thereof and relates to the field of sand prevention and treatment. The sand fixation cultivation medium comprises the following components in percentage by volume: 50-55% of sandy loam, 30-35% of wood flour, 10-15% of distillers' grains, 1-2% of slow release fertilizer, 0.02-0.04% of an aggregate agent, 0.02-0.04% of a water-retaining agent and 3-5% of a thermal insulation material, wherein the wood flour is powder ground from plate and wood processing leftover materials andhas a particle size of less than 5mm; the distillers' grains are distillers' grains produced by beer production in local brewery in a cultivation area and are ground to pass through a 5-mm sieve; thecontent of active ingredients such as nitrogen, phosphorus and potassium in the slow release fertilizer is more than or equal to 45%; the thermal insulation material refers to one or more of papermaking black liquid, liquid emulsified asphalt and humic acid. The medium using method comprises the steps: adding water into all sand fixation cultivation medium materials in a hydroseeder to be uniformly stirred, mixing sand fixation plant seeds, and spraying onto the sand surface, wherein the spraying thickness is 2-6cm. The sand fixation cultivation medium disclosed by the invention has beneficial effects of being good in heat insulation, water-retaining, resistant to freezing and thawing, wind erosion and rain wash and difficult to crack.

Description

technical field [0001] The invention relates to the technical field of sand prevention and control, in particular to a sand-fixing and planting substrate for aeolian sandy land in high-altitude areas and a use method thereof. Background technique [0002] Establishing a vegetation system for sand fixation is currently the most common technology for desert control. However, when relying on traditional soil transplanting and sowing methods for vegetation restoration, the vegetation coverage is low, and the aeolian sand on the surface of the sand is easily blown up by the wind and bury the vegetation. , thereby reducing plant survival. The Yajiang River Basin in Tibet belongs to the alpine and high-altitude area. To restore vegetation on the aeolian sandy land needs to overcome extreme natural conditions such as low temperature, high evaporation, high radiation, and wind and sand erosion. A strong covering layer prevents sand migration and burying plants; it also has good heat...
