Abstract
The present invention discloses one kind of multifunctional plant growth bag and its technological scheme. The plant growth bag consists of woven bag, fibrous cotton net, lining paper, seed and fertilizer layer and plant growth medium layer arranged from outside to inside as well as bag sealing. The plant growth bag is suitable for ecological slope protection and afforestation in mountain land andsandy land.
Description
Invention field
The present invention relates to a kind of multipurpose vegetation bag and technical scheme thereof, particularly a kind of multipurpose vegetation bag and technical scheme thereof that is applicable to protecting slope ecology and mountain region, sand ground afforestation.
Background technology
Infrastructure constructions such as highway, railway, water conservancy, agricultural, urban construction produce destruction to original landforms and vegetation inevitably, form the newly domatic of differing texture, different gradient.These new domatic entry material mainly are rock, weathered layer, cubsoil and backfill soil, not only hardness height, low, the poor water retention property of nutrient, and do not possess the granular structure and the permeability of soil, very be unfavorable for growth and development of plants.One runs into the erosion of wind and rain, and new domatic as easy as rolling off a log generation water and soil loss causes side slope top layer unstability, the destruction of form such as cause that finally side slope is slided, toppled over.
Carry out the protection of side slope top layer with the method for recovering side slope vegetation, promptly protecting slope ecology is the main flow of domestic and international in recent years side slope superficial protection.Ecological protection not only plays an important role to the stable side slope top layer, and the key measure that develops simultaneously as infrastructure construction and environmental protection, and its economic benefit, ecological benefits and social benefit are very tangible.Protecting slope ecology mainly is to rely on base of leaf of plant and the erosion that root system is resisted external force (wind, rain, current), and wherein the effect of root system is particularly important.Particularly the root system of tree and shrubs can go deep into soil inside, plays the effect of soil and slope protection.Therefore the ultimate aim of protecting slope ecology should be that foundation is the plant community of core with the tree and shrubs.
The nonwoven type vegetation bag of domestic production at present only is suitable for the growth of grass family draft, is difficult to directly bring up shrub or arbor group.The root system of draft is short and shallow, and water requirement is higher, and one runs into arid death easily, therefore existing nonwoven type draft vegetation bag is not only limited to the protective action of side slope, and the fraction of view recovery effects is low, and the cost height, in application facet very big deficiency is arranged, prospect is very unoptimistic.
Summary of the invention
One object of the present invention is to disclose a kind of multipurpose vegetation bag; Another object of the present invention is to disclose a kind of multipurpose vegetation bag that is applicable to protecting slope ecology and mountain region, sand ground afforestation; Another object of the present invention is to disclose a kind of technical scheme of multipurpose vegetation bag.
