Abstract

The invention relates to a non-irrigation greening method of a highway in a desert area. According to characteristics of an asphalt or asphalt concrete pavement, by utilization of rainwater collectedby the pavement, collection of irrigation water for greening is carried out in combination with a drainage trench of the pavement; in combination with the mature film-mulching and water-saving methodin an arid area, non-irrigation planting is carried out by selecting local drought-endurable and salt-tolerant plants in the arid area; soil water evaporation can be effectively reduced; soil salinization inhibition and entropy conservation can be facilitated; and survival and growth of green plants in a non-irrigation condition can be ensured. A lot of experiments show that: in a non-irrigation condition, the comprehensive survival rate of green vegetation in the first year is above 79%; the comprehensive survival rate in the second year is 63%; after reinforcement planting, the survival ratein the second year is 82%; the comprehensive survival rate in the third year is above 72%; on the premise that the maintenance cost is not increased, non-irrigation greening of the highway is realized by one-time investment; the method has great promotion potential; by means of the method, a lot of irrigation water for greening is saved; and furthermore, a lot of human and material resources is saved in the greening vegetation maintenance process.

Description

technical field [0001] The invention relates to the field of an irrigation-free greening method for roads in desert areas, in particular to an irrigation-free greening method for roads in desert 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 areas. . At the same time, the popul...
