Embodiment 1

[0020] a. Laying of rainwater collection facilities: through road reconstruction, replace the common curbstones in the experimental area with curbstones 1, and use the improved curbstones 1 to collect rainwater. The thickness of curbstones 1 is 12cm, and the height is 30cm. The length is 50cm, and the top of the stone 1 along the catchment road is inclined to open a semi-arc groove 2, the outside of the stone 1 along the catchment road is higher than the inner side by 2-4cm, and the center bottom of the half-arc groove 2 is 1cm lower than the inner edge 3, Along both sides of the road 4, the inner side of the Yanshi 1 of the catchment road is laid close to the asphalt road surface, and irrigation branch canals 7 are set on both sides of the road 4. In order to reduce the impact of water collection and greening on the roadbed of the road 4, the green irrigation branch canal 7 is 6m away from the roadbed of the road 4 , parallel to the road 4 direction, between the irrigation bra...

Abstract

The invention relates to an irrigation-free greening method for roads in a desert area. The method comprises the steps that according to the characteristics of asphalt or asphalt concrete pavements, rainwater accumulating on the pavements is utilized, and drainage grooves of the pavements are combined to collect greening irrigation water; in combination with a dry mature film-mulching water-savingmethod, local drought-tolerant salt-tolerant plants in an arid area are selected and subjected to irrigation-free planting; the evaporation of soil moisture can be effectively reduced, the saline-alkali reduction and moisture conservation of the soil are facilitated, and the survival and growth of the greening plants under irrigation-free conditions are ensured. It is shown through a large numberof experiments that under the irrigation-free conditions, the comprehensive survival rate of greening vegetation in the first year reaches 79% or above, the comprehensive survival rate in two years is 63%, the survival rate after two-year complementary planting is 82%, the comprehensive survival rate in three years reaches 72% or above, one-time input is involved, irrigation-free road greening isachieved on the premise of not increasing maintenance costs, and the popularization potentials are huge. By means of the method, not only is a large amount of greening irrigation water saved, but also a lot of manpower and material resources are saved in the maintenance process of the greening vegetation.

Description

technical field [0001] The invention relates to a road irrigation-free greening method in a desert area, which belongs to the road irrigation-free greening planting technology, and is a water-saving measure for road greening in arid areas. Background technique [0002] Highway greening can not only improve the driving environment along the highway, but also have the function of improving the safety of road driving, reduce the frequency of driving accidents, reduce the hazards of accidents, and can effectively prevent soil erosion within the scope of the road and reduce pollution caused by automobile exhaust. . With the deepening of the western development and the construction of the Silk Road Economic Belt, the construction of roads in the arid areas of Northwest my country is accelerating, and the amount of water resources for road greening is increasing day by day. The shortage of water resources has become a bottleneck restricting the construction of road greening in arid...
