Abstract
A method for controlling desert by arranging the ecological checks of root system features that when the main fibrous root, and the longitudinal and radial roots are considered, the current growth plant and the perennial plants are also considered. On said basis, the current growth plants are planted in the square frames to form effective sand barrier in present year. Its advantages are low cost and high effect.
Description
The present invention relates to a kind of plant comprehensive sand control new method, especially be suitable for the ecology comprehensive regulation of desert or sandy land.
Method of tackling desert can be divided three classes, plant (biology) sand control, engineering sand control (mechanical sand control) and nonirrigated farmland water-saving technology.Advantages such as engineering sand control (mechanical sand control) has instant effect, and short run effect is obvious, but do not possess ecological effect and long-term effect; The nonirrigated farmland water-saving technology is the technical measures of consolidation and auxiliary plant (biology) sand control process; Sand control that will be truly, then non-plant (biology) sand control does not belong to, and it is to solve the sand control root problem, has the method for ecological effect and long-acting effect.Though controlling sediment by plant so far theoretical from formal proposition from the developing direction of single arbor to Qiao, filling, careless combination, but there are not clear and definite technical measures and theoretical foundation, for example how to dispose the improvement that plant is beneficial to the growing tips of the plant living environment, how by floristics with give birth to the ecological environment etc. that configuration with perennial species improves growing tips of the plant then, all not have deeply comprehensively to relate to and study.The classical way of the embedding straw checkerboard barrier of those Jean-Yves Le D inventions of the scientist of Russia in 1845 is still continued to use in the foundation of sand-protecting barrier in the controlling sediment by plant process, and is auxiliary with clay tiling sand-protecting barrier, gravel tiling sand-protecting barrier, pitch sand-protecting barrier etc.So the controlling sediment by plant effect is unsatisfactory always so far.
Purpose of the present invention is exactly the deficiency that overcomes above-mentioned controlling sediment by plant, a kind of ecology comprehensive sand control new method is proposed, by root system of plant, plant species, the scientific allocation of living plant and perennial plant then, improve the ecological environment of growing point rapidly, restore vegetation reaches ecological effect and long-term effect.
The ecological grid comprehensive sand control of root system stereoscopic configurations of the present invention new method is to give birth to plant growing rapidly then on the frame edge of the square frame of square or rectangle with growth, forms ecological grid.Living then plant and perennial plant are planted in 1: 2～5 ratio in central area in this ecological grid delineation.Wherein the main root of these plants is long 20～30 centimetres, and main root is 1: 3～5 with fibrous root length ratio, and vertically and radially root is long than being 1: 5～8.
Aspect ratio square or rectangular box of the present invention is 1～3 meter: 1～3 meter, the frame of square frame is 8～15 centimetres along thickness.Living then plant comprises pale reddish brown sweet potato of light leaf and Itanlian rye, and described perennial plant comprises No. 1, river grass, lyme grass, husky living wheatgrass, red examination oat, alfalfa and high mountain red building.Living then plant and the thickness of sowing of perennial plant in ecological grid are 10～15 kilograms of seed/mus;
In the control of desert, sand bed top layer 30cm is the crucial aspect of controlling sediment by plant, this section water and soil, and it also is the most serious that nutrient runs off, and is that can controlling sediment by plant successful crucial section.The present invention is according to the soil fractal dimension of this section, in the configuration of plant, consider the allocation ratio of main root fibrous root, vertical diameter is to the long allocation ratio of root, perennial with give birth to factor such as plants configuration then, form main fibrous root at this section, root long rational stereoscopic configurations in vertical footpath forms living then plant in time for the shielding of perennial plant short-term with the effectively stereoscopic configurations on the concept of time of nutritional labelings such as detritus acid, the effect of raising controlling sediment by plant are provided.
The present invention selects growth rapidly, long 20～the 30cm of main root, main fibrous root ratio is 1: 3～5, the then living plant of the long ratio of vertical radially root between 1: 5～8, according to the sand ground wind direction, it is 1～3 meter that factors such as the gradient and sand content are directly planted into aspect ratio: 1～3 meter, thickness is 8～15 centimetres square frame, under the support of basic sand control technology, at the ecological grid sand-protecting barrier of promptly rapid formation then of plantation, the ratio in 1: 2～5 in ecological grid sand-protecting barrier plants living then plant and perennial plant.
The ecological grid comprehensive sand control of root system stereoscopic configurations of the present invention new method can form ecological grid sand-protecting barrier then.Be planted in the living then plant in the ecological grid, can grow to 20～30cm height then, the effect that having keeps out the wind fixes the sand, its underground root system, main root and fibrous root, vertically root and radially root, and interlaced with the root system of adjacent plant, be woven into organic network that fixes the sand of a solid, can effectively fix the sand, suction and solid water, the coming year its interlaced three-dimensional root system network remove to continue performance and fix the sand, outside the effect of solid water, also provide nutritional labelings such as humus for the plant in the ecological grid.Thereby improved the ecological environment in the ecological grid rapidly, for the growth of grid implants provides sufficient condition.The ecological grid of numerous root system stereoscopic configurations is unified into a slice, can check desertification rapidly, improves the ecological environment restore vegetation.Therefore the present invention has outstanding ecological effect and long-acting effect for the ecology method in comprehensive regulation sandy land or desert, and moreover, its cost only is 1/4～1/5 of a common embedding sand-protecting barrier, remarkable in economical benefits.If some industrial crops of breeding in ecological grid, its economic benefit is more obvious.
Accompanying drawing is the shape figure of ecological grid.
Embodiment
As shown in the figure, (1) district is ecological grid zone, and peripheral length and width are all 1 meter, and thickness is 8 centimetres square frame district.(2) district is the growing area of living then and perennial and industrial crops.Be planted in (1) district with the Itanlian rye that can grow fast, form plant sand block fast, shielding (2) is distinguished, and the nutrient in the protection and the coming year is provided for plant therebetween.(2) in the district by No. 1, river grass: the living wheatgrass of sand: alfalfa: Itanlian rye is 1.5: 0.5: 0.3: 0.5 ratio is planted these perennial plants and living then plant.(1) thickness of sowing of the plant in district and (2) district is all 12 kilograms of seed/mus.
Claims (4)
