Problems solved by technology

[0004] The regreening of rocky slopes is often limited by light, precipitation, soil, and topographical conditions. The regreening is usually covered with foreign soil and planted with plants, which has a certain regreening effect and better short-term visual effects. However, most of this kind of vegetation is Fast-growing and a single species can someti

Embodiment 1

[0050] A preparation method of nutrient thick liquid, comprising the following steps:

[0051] Mix 120g of CMC-Na, 10g of yeast extract, 10g of ammonium nitrate, 5g of magnesium sulfate, 10g of potassium hydrogen phosphate, 250g of agar and 120g of water, and mix thoroughly to obtain a medium thick liquid.

Embodiment 2

[0053] A rapid recovery method for rocky slopes, comprising the following steps:

[0054] 1) The viscous liquid obtained in Example 1 is adhered to a sieve plate with an aperture of 3 mm; the reed seeds are sprinkled on the sieve plate, and the weight ratio of the reed seeds to the mass of the viscous liquid is 1: 2 and scraped repeatedly Squeeze the sieve, collect the extrudate in the sieve, and dry to obtain the grass seed paste package;

[0055] 2) to galvanized iron wire as the shaft, 3 straws and the grass seed paste package are spirally intertwined to obtain a straw rope with a diameter of 1.0cm; add 3g grass seed paste package within every 10cm;

[0056] 3) Wrap the grass rope obtained in step 3) outside the 9 / 12mm drip irrigation pipe to obtain a wrapped drip irrigation pipe;

[0057] 4) Using straw, The galvanized iron wire and the grass seed paste package are 10g / m 2 The density of woven straw curtains;

[0058] 5) Dig water guide channels on the slope. The wa...

Embodiment 3

[0063] A rapid recovery method for rocky slopes, comprising the following steps:

[0064] 1) The viscous liquid obtained in Example 1 is adhered to a sieve plate with an aperture of 2 mm; the reed seeds are sprinkled on the sieve plate, and the weight ratio of the reed seeds to the mass of the viscous liquid is 1: 3 and scraped repeatedly Squeeze the sieve, collect the extrudate in the sieve, and dry to obtain the grass seed paste package;

[0065] 2) to galvanized iron wire as the axis, 2 straws and the grass seed paste package are spirally intertwined to obtain a straw rope with a diameter of 0.8cm; add 4g of the grass seed paste package within every 10cm;

[0066] 3) Wrap the grass rope obtained in step 3) outside the 9 / 12mm drip irrigation pipe to obtain a wrapped drip irrigation pipe;

[0067] 4) Using straw, Galvanized iron wire and grass seed paste package at 5g / m 2 The density of woven straw curtains;

[0068] 5) Dig water guide channels on the slope. The water ...

Abstract

The invention discloses a rapid rocky slope restoration method which comprises the following steps: 1) preparing a grass seed cream package coated with a nutritious base layer; 2) sandwiching the grass seed cream package to weave straw ropes; 3) winding the straw ropes outside a drip irrigation pipe; 4) sandwiching the grass seed cream package to weave straw mats; 5) digging a water channel; 6) laying the straw mats, the drip irrigation pipe and the straw ropes and fixing fixed anchor rods; and 7) watering. According to the method, sediment loss on the rocky slope can be effectively reduced, and vegetation is rapidly formed.

Description

technical field [0001] The invention relates to the technical field of infrastructure construction, in particular to a rapid recovery method for stone slopes. Background technique [0002] There are various slopes to be regreened in South China, among which rocky slopes are the most difficult. In particular, the stone slope of the abandoned quarry has become the most difficult to regreen among the stone slopes. The local temperature is high and the rainfall is heavy, and the annual rainfall is more than 1500mm. The characteristics of high temperature, rainy season, and hot and humid seasons make the weathering and pedogenesis of the soil very strong, and the cycle of biological matter is very rapid. The base is highly unsaturated and has low nutrient availability. The main obstacles to the regreening of stone slopes in abandoned quarries are the lack of soil, the scarcity of nutrients and the harsh external environment. Various obstacle factors have different degrees of h...
