Problems solved by technology

However, this method does not take into account that the plant straw will absorb nitrogen when it decomposes, so that the plants cannot grow normally due to nitrogen deficiency, and the plant straw contains a large number of bacteria. After construction, mold will grow on the surface of the slope. Causes plant diseases and insect pests on the slope surface
In addition, since there is no grid installed on the slope surface during the construction process, the thickness of the covering layer is only 2-3cm. growth substrate environment and cannot grow normally

Embodiment 1

[0010] Take 21.8kg of rape stalks crushed to a length less than 2cm, 0.41kg of urea, 0.42kg of potassium chloride, 0.31kg of superphosphate, 77kg of planting loam, 0.02kg of chlorinated nitrobenzene, and 0.04kg of perennial ryegrass seeds, and mix them with a mixer Uniform; install anchor rods on the stone slope with a slope of 1:0.75, and fix 14# galvanized welded steel wire mesh (mesh hole 50×50mm) on the slope with a supporting plate, and the distance between the wire mesh and the slope is 4cm; Use the improved concrete sprayer to spray the mixture onto the slope, add 111Kg of water during the spraying process, and the spraying thickness is 10cm to form the slope covering layer as shown in Figure 1. Among them, 1 is the stone slope, 2 is the anchor rod, 3 is the support plate, 4 is the grid, and 5 is the slope covering layer.

[0011] Seven days after the construction, Bermudagrass began to germinate, and the vegetation coverage rate reached over 95% one month later. After ...

Embodiment 2

[0013] Take 28.4kg of straw straw, 0.51kg of ammonium nitrate, 0.51kg of potassium sulfate, 0.50kg of superphosphate, 70kg of planting loam, 0.04kg of carbendazim, and 0.04kg of bermudagrass seeds crushed to a length of less than 3cm, and mix them evenly with a mixer ;Anchor rods are installed on the stone slope with a slope of 1:0.5, and 14# galvanized welded steel wire mesh (mesh hole 50×50mm) is fixed on the slope surface with a supporting plate, and the distance between the wire mesh and the slope surface is 6cm; The above-mentioned mixture is sprayed onto the slope with an improved concrete sprayer, and 91Kg of water is added during the spraying process, and the spraying thickness is 14cm to form a slope protection covering layer as shown in Figure 1.

[0014] Four days after construction, ryegrass began to germinate, and one month later, the vegetation coverage rate reached over 95%. After two to three months of construction, the vegetation grew well, and the three-phase ...

Abstract

The method of utilizing plant straw to green rocky side slope includes the steps of: crushing or cutting plant straw into length less than 4 cm and mixing with soil, chemical fertilizer and disinfectant in certain proportion; fixing lattice with anchor poles and support boards over the surface of the rocky side slope with some interval being maintained in between; and spraying the mixture with high pressure sprayer to the slope to form covering layer while adding water. With low cost and being capable of forming covering layer with high anticorrosion capacity, the said method can be widely used in greening rocky side slope during building railway, highway, bank, mine and hydroelectric engineering.

Description

technical field [0001] The invention relates to a method for afforesting a side slope, in particular to a method for afforesting a rocky side slope by using plant straws. Background technique [0002] In order to prevent soil erosion and protect the ecological environment, greening is often carried out on both side slopes of roads, railways, river banks, etc. to form slope protection covering layers. Disclosed a kind of basic covering layer manufacturing process as German patent DE19613389, its invention point is that sludge, chopped plant stalks, grass seeds and water are mixed in a certain proportion, spread on the slope surface after stirring evenly, with To achieve the purpose of greening. However, this method does not take into account that the plant straw will absorb nitrogen when it decomposes, so that the plants cannot grow normally due to nitrogen deficiency, and the plant straw contains a large number of bacteria. After construction, mold will grow on the surface ...
