Slope surface punching, planting and greening method

Abstract

The invention discloses a slope surface punching, planting and greening method. The method comprises the steps that slope cutting treatment is conducted on a surface soil layer of a slope surface; a special drill bit is used for punching holes in the cut slope surface to form circular planting holes; during punching, the holes face downwards and form an included angle of 55-65 degrees with the slope surface, and the holes are arranged up and down to form a shape like a Chinese character "pin"; a PVC pipe is divided into two parts in the axis center line direction, a notch is formed in one endof the cut PVC pipe to form a growth groove, the end, provided with the growth groove, of the PVC pipe is obliquely inserted into the planting hole, the growth groove is exposed, and a semicircular opening of the PVC pipe faces upwards to form a water collecting groove; a drought-resistant water-retaining agent is scattered at the bottom of the planting hole, container seedlings with soil balls are fed into the bottom of the planting hole through a water collecting pipe, and mellow soil is backfilled; and after planting, the seedlings are watered and continuously tended for two years, and theseedlings are well watered, managed and protected according to the soil moisture content in March, July, August and November every year. According to the method, water and soil loss can be effectivelyprevented, and the effective greening area is increased.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and management, and in particular relates to a method for perforating and planting greening on slopes. Background technique [0002] In recent years, with the development of the economy, the occupation, avoidance, access and excavation of roads, railways, quarrying, mining, and real estate development have formed a large number of engineering secondary exposed slopes, which often appear in the middle of green nature. The area is bare and exposed soil slopes. These bare slopes are fragmented due to formation and historical reasons, which are natural hidden dangers that cause soil erosion, dust and smog, threaten industrial and agricultural production, and people's production and life safety. Structures and service functions are destroyed, exacerbating the deterioration of the human living environment and ecosystem degradation. Loess exposed steep slopes generally have the followi...

Problems solved by technology

[0003] The treatment of exposed slopes in China mainly relies on engineering reinforcement measures, such as concrete, metal mesh, grouted stones, etc. to build retaining walls, anchor retaining walls, anti-slide piles, etc., mainly focusing on the stability and safety of slopes, without considering vegetation The problem is that part of the natural ecology will be destroyed during the treatment process, and the landscape effect is poor. The slope after treatment has not fundamentally curbed the occurrence of soil erosion. In recent years, the ecological treatment of bare slopes has become more and more popular. focus on

According to the State Forestry Administration's "Technical Specifications for Vegetation Restoration on Bare Slopes", exposed slopes above 65° belong to steep cliff slopes and need to be greened with holes and barriers. The method of manually punching holes with a crescent shovel has problems such as low efficiency, different punching specifications, difficulty in watering and tending, and high treatment costs. The treatment area is extremely limited and cannot be widely promoted.
