Abstract

The invention relates to a composite for forestation, wind protection and sand fixation along the line of railway or highway. The composite is prepared by the following raw materials in proportion by weight: 50-95 parts of polystyrene, 15-50 parts of plasticizer, 60-150 parts of organic solvent, 5-25 parts of sodiumhydroxymethyl cellulose, 15-35 parts of dodecyl ammonium chloride, 100-300 parts of distilled water, 30-75 parts of gelantinizer, 3-20 parts of humectant and 0.002-0.03 part of photosensitive curing agent. The composite in the invention is diluted by adding water until the solid-containing amount in the composite is 1-10%, the diluted composite can be sprayed on soil and desert and then solidified to a ground film; and the composite takes the effect of preventing earth, fixing sand and preventing a large amount of water from evaporating, and has important sense for improving soil, managing sand, vegetating and foresting and improving ecological environment.

Description

technical field [0001] The invention relates to a technical afforestation method in arid areas, in particular to a windproof and sand-fixing composition for afforestation along a railway or expressway and a preparation method thereof. Background technique [0002] Along the railway or highway in the desert, in order to protect the smooth flow of the railway or highway and prevent the invasion of wind and sand, it is stipulated that afforestation should be planted. The conventional method of afforestation is to irrigate after planting. Irrigation involves not only water sources but also equipment investment and labor. and forest management issues. At present, there are also reports on afforestation without irrigation, but none of them mentioned the survival rate of afforestation. There is a lack of sufficient technical support in terms of precipitation, soil moisture limitation, selection of plant species, planting techniques and stability. The limiting factor affecting des...
