Abstract
The invention discloses a bionomic control method for the shale side slope. The method can ensure that a shrubby seed is embedded into the small opening of a shale side slope body to take root and grow through afforestation spray-sowing, thereby improving the bionomic control effect of the side slope. The method includes the following steps: (1) the side slope is napped, rubble, detritus and sundries are cleaned up, and the slope surface is brushed; (2) a soil substrate layer sprays on the side slope, and the soil substrate layer is a mixed material containing the shrubby seed and the pig blood; (3) the maintenance is performed. The invention adopts a method of food attraction and insect insemination, namely, the soil substrate layer is sprayed with the mixed material containing the shrubby seed and the pig blood, by utilizing the biologic dependence relationship of ants to the pig blood, when collecting food, the ants draw the pig blood with the seed into the small opening of the side slope, so as to ensure that the shrubby seed is embedded into the small opening of the shale side slope body to take root and grow, to quickly reforest and stabilize the side slope, thereby effectively improving the bionomic control effect of the side slope. The latter curing for the shrubbery growing is not needed, thereby greatly saving the cost for reforesting and maintaining the side slope.

Background technology
Along with developing rapidly of China's highway, people have higher requirement to the expressway construction quality, usually adopted in the past and paved protection and sealing safeguard procedures, but since construction complicated, involve great expense and influence the environment of both sides of highway and ecoscape being eliminated gradually, and the side slope retaining anti-with afforest the ecological protection system that combines and obtained application more and more widely.
At present, the ecological protection of rocky slope adopts the method for sowing grass seeds by duster of afforesting more, and the core of this method is to build one at slope of rock mass can allow growth and development of plants and plant the porous rock-steady structure that matrix is not washed away.It utilizes special spray to mix and is ejected on the scar after machinery adds water with mixed dry materials such as soil, fertilizer, organic matter, water-keeping material, plant seed, cement, because the cementation of cement, said mixture can form the hardenite that one deck has continuous gap at rock surface.Sclerosis to a certain degree makes plantation exempt from erosion, and is filled with seed, soil, water-keeping material etc. in the space, and the space is the packing space of plantation matrix, is again the growing space of root system of plant.Because the thickness of plantation matrix is limited, only the preferential species grass can not form abundant ecoscape with arbor or shrub miscegenation usually.And shale side slope is loosely organized, physical weathering is strong, side slope is subjected to the rain drop erosion meeting to produce a large amount of water and soil loss, and traditional greening method of sowing grass seeds by duster can't make the seed of arbor or shrub be deep in the hole of shale side slope body to take root and grow, be unfavorable for the protecting slope ecology effect that reaches stable.
Summary of the invention
Technical problem to be solved by this invention provides a kind of ecological protection method of shale side slope, is deep in the hole of shale side slope body and takes root and grow by the sow grass seeds by duster seed that can make shrub of greening, thereby improve the effect of protecting slope ecology.
The technical solution adopted for the present invention to solve the technical problems is: the ecological protection method of shale side slope of the present invention, comprise the steps: 1. to repair side slope, and cleaning slabstone, rubble and foreign material are brushed domatic clearly; 2. to domatic injection soil matrix layer, this soil matrix layer is the compound that contains shrub seed and pig blood; 3. maintenance.
The thickness of described soil matrix layer is 7～8cm.
Shrub seed consumption is 10～20g/m in the described compound
2, the weight ratio of shrub seed and fresh pig blood is 1: 15～20.
After shrub seeds growth 20～30 days, again to the soil matrix layer grass-seed compound of sowing grass seeds by duster.
The invention has the beneficial effects as follows, adopt the method for " food is lured, insect sow ", promptly on the soil matrix layer, spray the compound that contains shrub seed and pig blood is arranged, utilize the biological dependence of ant to pig blood, when searching for food, ant the pig blood of band seed can be dragged in the side slope hole in the lump, the seed of shrub is deep in the hole of shale side slope body takes root and grow, but fast greening and stable side slope, thus improve the effect of protecting slope ecology effectively; The shrub growth is saved the cost of greening side slope maintenance in a large number without the later stage maintenance.
The present invention is equally applicable to the ecological protection of porous crack side slopes such as husky mud stone and verrucano.
Embodiment
The present invention is further illustrated below in conjunction with embodiment.
The present invention has arrived application in domestic section part side slope (the about 110 kilometers) afforestation project of national highway 319 lines (G319) Ziyang, Sichuan Province.This project side slope lithology has argillaceous siltstoue folder mud stone, argillaceous siltstoue and thin layers of mudstone alternating layers, sandstone etc. based on thin layers of mudstone, argillaceous siltstoue, has a small amount of high slope to exist on the way.Side slope protection is avoided ecological closed protection as far as possible, and adopt open plant ecological protection system, promptly under the situation of geological conditions permission, replace stiff bricklaying bank protection with the natural vegetation protection, the artificial engineering vestige that weakens reaches and the harmony of natural environment on every side.
According to slope height and the gradient, geology and soil condition, selecting for use respectively directly sows grass seeds by duster irritates grass, dibbling arbor linked network is sowed grass seeds by duster and irritated grass etc.See table 1 for details.
Table 1 protecting slope ecology form
The step of shale, husky mud stone and the construction of verrucano highway section greening side slope is specific as follows:
1. finishing side slope, cleaning slabstone, rubble and foreign material, brush domatic clearly, to guarantee stablizing of side slope, simultaneously for pave three dimensional network, wire netting is laid a solid foundation.
2. to domatic injection soil matrix layer.
Preparation soil matrix layer compound, soil, shrub seed, pig blood, cement, wood fibre, composite fertilizer etc. are added water by a certain percentage mix and stir the formation compound, artificial earthing or with pulp shooting machine equably sprayed coating on domatic as the soil matrix layer, the about 7～8cm of thickness.Shrub seed consumption is 10～20g/m in this compound
