Abstract
The invention provides a method for preventing landslides. According to the method, parthenocissus tricuspidata, merremia boisiana and dodder are planted on a slope. The method comprises the following steps: treating seeds, including taking 10-15 parts of parthenocissus tricuspidata seeds, 5-10 parts of merremia boisiana seeds, 8-12 parts of dodder seeds, 60-75 parts of water, 3-5 parts of potassium dihydrogen phosphate, 2-3 parts of dipotassium hydrogen phosphate, 1-3 parts of urea and 150-200 parts of sandy soil by weight, uniformly mixing the materials, and accelerating germination of the seeds in culture pots at 25 DEG C for 24-36 h to obtain sandy seed soil; excavating planting grooves in the mountain slope along horizontal contour lines, sowing the sandy seed soil in the excavated planting grooves, and filling the excavated planting grooves with organic fertilizer and borrowed soil; spraying water to keep the soil damp, and covering the soil with no-woven fabric to shelter the soil from wind, rainstorms and the sun; two months later, pinching and pruning vines; and maintaining plants, including watering the slope once every day except rainy days to ensure that the slope is damp. Through the method, quick vegetation restoration and slope greening of highways, railways and rivers can be effectively realized, structural stability is realized, and the purposes of preserving water and soil and preventing landslides are achieved.
Description
technical field [0001] The invention relates to an ecological restoration method for environmental protection, in particular to a method for preventing landslides. Background technique [0002] With the acceleration of the infrastructure construction of highways, high-speed railways, industrial and civil buildings, and water conservancy projects in our country, it is often necessary to excavate a large number of slopes. If these slopes are not protected and greened, it will often lead to a large number of secondary bare land and serious soil erosion, causing landslides, resulting in traffic interruption, river silting, and accidents. [0003] Therefore, preventing landslides on roads, railways, and river slopes has become a common concern in various countries. According to the actual situation, how to adapt measures to local conditions and apply treatment according to the slope, quickly, efficiently and cost-effectively realize the stability of the slope structure, prevent ...
