Description
Technical Field
The invention relates to the technical field of wind and sand treatment of agricultural straw resources in an ecological environment, in particular to a sunflower straw sand barrier strip and a sunflower straw sand barrier laying method.
Background
Due to wind and sand disasters, crop yield is reduced, traffic is damaged, air quality is reduced, various respiratory diseases are caused, and production and life of people are seriously influenced.
The most effective and quick control or slowing down the movement of the sand and wind on the surface of the desert is to arrange sand barriers in the desert sand control of the areas with strong sand and wind activities. On the basis, the vegetation is restored to finally achieve ecological restoration under the condition that the vegetation grows. As can be seen, setting the sand barrier to fix the sand is a key step.
Many achievements exist on the material and arrangement mode of arranging the sand barrier. The wheat straw sand barrier used in large area has obvious on-site effect due to easily available material, simple construction and high construction efficiency. With the economic development, the wheat planting area of partial areas is reduced, and the material cost is increased year by year. The researchers begin to try to use other materials for replacing the sand barriers, and the problems that the sand barriers are made of shrub branches such as salix mongolica, salix mongolica and the like, and the sand barriers are made of degradable fiber materials and non-degradable nylon net sand barriers and the like which are processed by using a textile technology are solved to a certain extent. However, some non-degradable materials also cause secondary pollution to the environment, and the weaving of some degradable materials increases the cost of raw materials and the cost of manufacturing.
The earliest clay sand barrier is poor in clay water permeability, so that rainfall infiltration in arid areas is reduced, clay acquisition can damage surface soil in soil borrowing areas, water and soil loss is caused, and the clay sand barrier gradually exits from the eyes of people. The wheat straw sand barrier is made of wheat straws, is easy to decay after being subjected to rain, wind and sun, has a short service life of about 3 years, and has the advantages that in recent years, due to adjustment of rural production structures and development of related industries, the number of raw materials of the wheat straw sand barrier is reduced, so that the manufacturing cost of the wheat straw sand barrier is increased continuously. The sand barrier of salix mongolica and salix mongolica is only used in partial inner Mongolia areas due to regional limitation. Therefore, new technical measures must be found, and a material and a method for manufacturing the sand barrier must be found.
The straw resource is rich in the big agricultural country in China. In addition to the above-mentioned wheat straw and rice straw, there are corn straw and sunflower straw, however, most of them are used for feed processing because of their high feed value. Because the feed value of sunflower straws is low, the planting area of the sunflower straws which is an important economic crop in arid regions tends to increase year by year in recent years, but the straws are mostly discarded and incinerated as agricultural wastes, the straw incineration is prohibited along with the enhancement of the environment protection meaning of people, and a large amount of sunflower straws are discarded in the field and are not fully developed and utilized. The sunflower straw is not utilized to manufacture the sand barrier, the main reason is that the laying speed is low in the construction process, and the labor cost is 5-10 times of that of the wheat straw sand barrier. Therefore, the sand barriers are arranged in the research and development of the related sunflower straw processing, the reutilization of agricultural waste straw resources can be realized, and particularly the harmless and green conversion and application of the waste sunflower straw in the technical field of ecological environment wind and sand treatment are realized.

Example two
In the embodiment, the sunflower straw sand barrier is laid by adopting at least the following two schemes:
firstly, as shown in fig. 5 and 6, the sunflower stalk sand barrier in the shape of a strip is as follows:
the layout condition is as follows: the strip-shaped arrangement is selected when one main wind direction or two opposite wind directions are main wind directions. A plurality of sunflower straw sand barrier strips (A in the figure) are distributed in a plurality of rows, wherein the arrangement direction of the sunflower straw sand barrier strips is vertical to the main wind direction, the strip spacing between two adjacent sunflower straw sand barrier strips is generally 1m, 2m and 3m … …, the porosity of the sand barrier is 40 percent, 50 percent and 60 percent, the height of the sand barrier is 20cm-40cm, the height is unequal to be a low vertical type, the aim is to fix sand on site, and the burial depth of the sand barrier is not less than 20 cm; for the height more than 50cm and less than 1m, the purpose is to block the drift sand in the border, the buried depth of the sand barrier is not less than 30cm, and the sand barrier is ensured not to be blown down; the height, the porosity and the belt distance of the sand barrier determine the sand blocking and fixing effects of the sand barrier. The sand barrier has small porosity, high barrier height and narrow belt spacing, and the sand blocking and fixing effect is better.
Wherein the porosity is calculated according to the following formula:
Generally, for the low-standing sand barrier, the distance between the belts (the distance between two adjacent sunflower straw sand barrier belts) arranged in a region with strong wind and sand is not more than 3m, the porosity is not higher than 60%, and the barrier height is not lower than 20 cm.
For the high vertical sand barrier, the purpose of setting is to intercept drift sand passing through the border, the belt spacing is generally 1-5 times of the height H of the sand barrier, the ascending spacing of a flat sand ground can be enlarged, and the row spacing of a sand dune with a larger gradient is properly reduced; the porosity of the sand barrier is not higher than 60%, and the height of the sand barrier is not more than 100cm generally.
More specifically: according to the main wind direction of sand dunes (sand lands), grooves with the depth of 20cm and the width of 10cm are arranged in the arrangement position along the direction perpendicular to the main wind direction, a plurality of sunflower straw sand barrier basic units are sequentially arranged into lines according to the length of the grooves, the sunflower straw sand barrier basic units are connected with one another at the end through connecting pieces 14 to form a sunflower straw sand barrier strip (sunflower straw sand barrier for short), one end of the sunflower straw sand barrier strip is placed in a shallow groove, sunflower straws 2 are righted (namely in a vertical state), sand is filled in the grooves and then is compacted, and a sand bank (designated as a in the figure) with the height of about 10cm is piled. Generally, before a sunflower straw sand barrier strip is put in, the length of the sunflower straw sand barrier strip is preferably 6m, and after the sunflower straw sand barrier strip is put in, the sunflower straw sand barrier strip can be fixed through a connecting piece.
After finishing laying 1 sand barrier, excavating a second groove along the previous sunflower stalk sand barrier at a distance of L2, and repeating the laying mode until all the required areas are laid. The length of L2 is determined according to the layout requirement, and L2 generally does not exceed 5-10 times of the height H of the sand barrier; the strip-shaped sand barriers are generally arranged in an area with only one main wind direction or two opposite main wind directions (namely the included angle of the main wind directions is 180 degrees).
Secondly, as shown in fig. 5, 7, 8, 9 and 10, the sunflower stalk lattice-shaped sand barrier is as follows:
when the main wind direction is two or more than two opposite wind directions, and the main wind direction is not equal, the grid-shaped sand barrier is arranged. The lattice-shaped sand barrier is arranged by arranging the bottom of a sand dune to the top or the middle of the sand dune. Because the sand barrier is integrally designed into a latticed shape, corresponding sand barriers are arranged in all directions to shield the sand barrier, and the relation between the sand barriers and the wind direction does not need to be considered during setting.
The height of the arranged sand barrier is generally 20-40cm, and the side length of the grid-shaped sand barrier is generally 1m-3 m. The lattices of the sand barrier can be squares, rectangles, diamonds and triangles. The arrangement rule is that a steep slope is provided with a small specification, and a gentle slope is provided with a large specification.
Taking the grid shape of the sand barrier as a square or rectangle (as shown in fig. 6 and 7), specifically: according to the requirement of arranging the real-land sand barriers, firstly, transversely and longitudinally arranging grooves in sand dunes or sand lands, after the grooves are arranged, assembling basic sunflower straw sand barrier units into a strip with the side length of L3 at the end through a connecting piece 14 (namely, a penetrating connecting piece 14 at an interband connecting hole 13), transversely burying the sand barriers in the sand to form sand ridges by treading, then, assembling 2 groove longitudinal unit grids through the interband connecting holes 13 and the connecting piece 14, and finally, burying the sand barriers in the sand to form the sand ridges by treading. The sand barriers in one area of the sand barriers in the two rows of grids are laid, the laying area is completely laid by analogy, and the whole sand barriers are connected into a whole through the connecting pieces 14, so that the wind resistance and the lodging resistance of the sand barriers are enhanced.
The arrangement of the diamond-shaped sand barriers and the rectangular sand barriers is consistent with the arrangement of the positive-direction sand barriers (as shown in figure 8);
the triangular sand barrier layout (as shown in fig. 10) is also that a groove is firstly formed, three sides (each side must contain at least one complete sunflower straw sand barrier basic unit) corresponding to a triangle are overlapped at the end parts, connecting strips 11 of the sunflower straw sand barrier basic unit where the three sides are located are fixed through inter-belt connecting holes 13 and connecting pieces 14 to form a vertex at the overlapped part, the angle of each side is adjustable, the side is fixed transversely and longitudinally, and sand barriers are buried in one area by 2 lines, and sand stalks are piled up; and the sand barriers in the whole layout area are laid by analogy. The triangle itself has a stable phase, and the formed sand barriers are connected together through the connecting piece 14, so that the stability of the sand barrier is higher than that of a square, a rectangle and a rhombus.
Lattice-like sand barriers are typically placed in areas where there are two main wind directions (the angle between them is less than 180 degrees) or more.
It needs to be added that: in the sunflower straw sand barrier basic unit, the distance (namely the porosity) between two adjacent sunflower straw fixing holes 12 is flexibly set according to actual needs, the set porosity, the set line spacing and the sand barrier height can be adjusted according to field conditions, a unit module is formed, the laying efficiency is improved, and the labor cost is saved.
In the process of manufacturing the sunflower straw sand barrier strip, the basic sunflower straw sand barrier unit is manufactured and molded by adopting a sand barrier mold, wherein the sand barrier mold has the following specific structure:
as shown in fig. 11 and 12, the sand barrier mold comprises a mold table surface 3, a strip-shaped limit table 31 extending towards two sides of the mold table surface 3 is protrudingly arranged at the upper part of one end of the mold table surface 3, the limiting table 31 is used for abutting against and facing the end parts of the plurality of sunflower straws 2, the upper surface of the die table 3 is provided with a plurality of channels 32 (the cross section of each channel 32 is semicircular) for embedding and containing the sunflower straws 2, the channels 32 extend along the direction vertical to the limiting table 31, and extends to the other end of the mold table 3, a plurality of the channels 32 are distributed in parallel at intervals, the upper surface of the die table 3 is provided with a plurality of slots 33 extending towards both sides thereof, the plurality of slots 33 are distributed between both ends of the die table 3 at intervals in parallel, and the slots 33 are used for inserting the connecting strips 11 which are vertically arranged in a transverse direction.
The manufacturing method of the sunflower straw sand barrier basic unit comprises the following steps:
s1, inserting the connecting strips 11 into the two slots 33 of the sand barrier mould respectively, and ensuring that after the connecting strips 11 are inserted, the sunflower stalk fixing holes 12 on the connecting strips are correspondingly superposed with the channels 32 of the sand barrier mould one by one;
s2, pushing the sunflower stalks 2 into each of the channels 32 one by one, and making the sunflower stalks 2 pass through the corresponding sunflower stalk fixing holes 12 of the two connecting strips 11 until the ends of the sunflower stalks 2 abut against the limiting table 31;
s3, taking the connecting strip 11 out of the sand barrier mould to form a sunflower straw sand barrier basic unit.
Wherein, each mould is used for manufacturing a sand barrier basic unit (the length is 1m, and the length can also be flexibly arranged), two connecting strips 11 of each sunflower straw sand barrier basic unit are respectively positioned at the top and the bottom of the manufactured sand barrier strip by 10cm-15cm, when the manufacturing is started, the two connecting strips 11 are firstly inserted into a plurality of slots 33, and sunflower stalk fixing holes 12 of the connecting strips 11 are positioned at the channel 32 (after the connecting strips 11 are inserted, the lower parts of the sunflower stalk fixing holes 12 are superposed with the channel 32). After the sunflower straw sand barrier basic units are manufactured, the sunflower straw sand barrier basic units are combined at the end parts of the connecting strips 11 through the connecting pieces 14 to be arranged linearly, and finally, the whole sunflower straw sand barrier strip is formed. The manufactured sunflower straw sand barrier strip can rotate at any angle at the connecting piece, so that the combination of the square sand barrier, the diamond sand barrier and the isosceles triangle sand barrier at the later stage is facilitated. The length of the strip sunflower stalk sand barrier is based on the basic unit of the sunflower stalk sand barrier, and a plurality of strips can be combined according to the laying requirement.
Generally speaking, please refer to the results of the research related to the movement of wind and sand, when the wind and sand meet an obstacle, the wind rises due to resistance, the sand carrying capacity is reduced, and the sand and the wind separate and settle. Secondly, when wind passes through gaps of the sunflower stalk sand barriers, airflow disturbance occurs, the consumption capacity and the wind speed are reduced, the shearing force is reduced, the wind energy is reduced, and the ground surface sand cannot be driven, so that the ground surface is protected from wind erosion, and the purposes of preventing wind and fixing sand are achieved. The technology takes the sunflower straw which is agricultural straw waste as a main raw material, and the sunflower straw is woven into a fence type structure according to a certain specification and is arranged in a sand and wind damage area such as desert, sand and the like; the sand barrier material has the advantages of simple structure, easy assembly into a rowed belt type and a square type, long service life, convenient construction and simple operation, greatly reduces the manual weaving cost, is environment-friendly, does not cause secondary pollution to the environment, can increase the fertility of the desert when the sand barrier material is rotten, and is easy for vegetation recovery; particularly, the weaving method provided by the patent can reduce the laying cost to a great extent, is beneficial to popularization and application of the sunflower stalk sand barrier, and has important significance for relieving insufficient resources, reducing environmental pollution (the sunflower stalk sand barrier can be rotted after a plurality of years to increase soil fertility and not pollute the environment) and realizing ecological transformation and application of the waste in the farming and animal husbandry and promoting the sustainable development of agriculture.
