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 sometimes cause biological invasions and have a short-term effect
Therefore, in combination with some plant physiological characteristics and technological innovation, a greening plan for rocky slopes in abandoned quarries is established to solve the problem that vegetation cannot grow on rocky slopes or it is difficult for vegetation to survive after germination.

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 method for rapid restoration of vegetation on stony slopes, comprising the following steps:

[0054] 1) Adhere the viscous liquid obtained in Example 1 to a sieve plate with an aperture of 3 mm; sprinkle reed-like seeds on the sieve plate, the ratio of the weight of the reed-like seeds to the mass of the viscous liquid is 1:2; repeat Squeeze and squeeze the sieve holes, collect the extrudate in the sieve holes, and dry to obtain the grass seed paste package;

[0055] 2) Take the galvanized iron wire of φ0.3mm as the axis, and spirally interweave 3 straws with the grass seed paste package to obtain a straw rope with a diameter of 1.0cm; add 3g of 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) Use straw, φ0.3mm galvanized iron wire and grass seed paste package at a rate of 10g / m 2 The density of woven straw curtains;

Embodiment 3

[0063] A method for rapid restoration of vegetation on stony slopes, comprising the following steps:

[0064] 1) Adhere the viscous liquid obtained in Example 1 to a sieve plate with an aperture of 2 mm; sprinkle reed-like seeds on the sieve plate, the ratio of the weight of the reed-like seeds to the mass of the viscous liquid is 1:3; repeat Squeeze and squeeze the sieve holes, collect the extrudate in the sieve holes, and dry to obtain the grass seed paste package;

[0065] 2) Take the galvanized iron wire of φ0.4mm as the axis, and spirally interweave 2 straws with the grass seed paste package to obtain a straw rope with a diameter of 0.8cm; add 4g of 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) Use straw, φ0.4mm galvanized iron wire and grass seed paste package at a rate of 5g / m 2 The density of woven straw curtains;

Abstract

The invention discloses a method for rapid restoration of stone slope vegetation, which comprises the following steps: 1) preparing a grass seed paste bag wrapped with a nutrient base; 2) weaving a grass rope with the grass seed paste bag; 3) winding the drip irrigation pipe Straw rope; 4) Weaving straw mats with grass seed paste; 5) Digging water guide channels; 6) Laying straw mats, drip irrigation pipes and straw ropes and fixing anchors; 7) Watering. The method can effectively reduce the sediment loss of the stony slope and quickly form vegetation.

Description

technical field [0001] The invention relates to the technical field of infrastructure construction, in particular to a method for quickly repairing stone slope vegetation. 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...
