Abstract
The utility model discloses a straw retaining dam which aims at exerting good effect of preventing water loss and soil erosion and also providing a new method for the recycling and utilization of the straw of crops. The straw retaining dam is formed by extruded straw stubs (10) buried along the boundary of cultivated lands and each extruded straw stub (10) is closely arranged into rows. The straw retaining dam has the advantages of providing the new method for the recycling and utilization of the straw of crops by utilizing rich straw resource in rural areas, being capable of exerting good effect of preventing water loss and soil erosion and being beneficial to soil accumulation, increasing organic matter and increasing the output of crops.
Description
Technical field
The utility model relates to the anti-water and soil loss facility in arable land, and particularly a kind of is the check dam of material with the stalk.
Background technology
China's severe water and soil erosion, especially south is ploughed more serious.Because reducing, soil erosion, nutrient cause soil depletion.Simultaneously, because sedimentation causes the river course to stop up, have a strong impact on water transport and downstream water conservancy engineering safety.On the other hand, a large amount of agricultural crop straw of the annual generation of China's agricultural production, except that part was used as the feed and the raw material of industry, comprehensive utilization ratio was extremely low, and the overwhelming majority is burned.Not only waste resource but also environment is caused severe contamination, have influence on the both urban and rural residents's life and the safety that road traffic, civil aviaton fly.For forbidding crop straw burning, country is annual to spend great amount of manpower and material resources, but effect is very unobvious, and economic loss is huge.
The utility model content
Technical problem to be solved in the utility model provides a kind of stalk check dam, can play the good effect of preventing erosion, and the recycling for agricultural crop straw provides a kind of new way again.
The technical scheme that its technical problem that solves the utility model adopts is: stalk check dam of the present utility model is characterized in that: this stalk check dam is made of the extrusion modling stalk stake of burying underground along border, sloping arable land, between each extrusion modling stalk stake near in a row.
The stake of described extrusion modling stalk is made of stalk briquette stem stem and the waterproof coating that is covered on its external surface.
The stake of described extrusion modling stalk becomes single or arranges more and establish.
The beneficial effects of the utility model are, utilize the abundant stalk resource in rural area, for the recycling of agricultural crop straw provides a kind of new approach, can play the good effect of preventing erosion, and help the soil accumulation and increase organic and improve the output of crops.
Description of drawings
This manual comprises following three width of cloth accompanying drawings:
Fig. 1 is the vertical view of the utility model stalk check dam;
Fig. 2 is the longitudinal section schematic diagram of the utility model stalk check dam;
Fig. 3 is the schematic cross-sectional view of extrusion modling stalk stake in the utility model stalk check dam.
Parts shown in the figure, toponym and corresponding mark: extrusion modling stalk stake 10, stalk briquette stem stem 11, waterproof coating 12.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
See figures.1.and.2, stalk check dam of the present utility model is made of the extrusion modling stalk stake of burying underground along border, sloping arable land 10, between each extrusion modling stalk stake 10 near in a row.When raining, rainwater (carrying mud secretly) slowly soaked by underground under the obstruction of extrusion modling stalk stake 10, and silt is owing to stopping of check dam deposits, thus the minimizing soil erosion.Time is permanent, and extrusion modling stalk stake 10 is become thoroughly decomposed naturally and rotted, and increases the soil organism, and pollution-free to the soil, the extrusion modling stalk stake 10 that more renews is also very convenient.Therefore, the utility model can effectively utilize the abundant stalk resource in rural area, for the agricultural crop straw utilization provides a kind of new approach, can play the good effect of preventing erosion, and helps the soil accumulation and increase organic matter and the output that improves crops.
With reference to Fig. 2 and Fig. 3, have long application life for making extrusion modling stalk stake 10, described extrusion modling stalk stake 10 is made of stalk briquette stem stem 11 and the waterproof coating 12 that is covered on its external surface.For ease of processing, the cross section of described extrusion modling stalk stake 10 is rounded or square.Described extrusion modling stalk stake 10 can singlely be laid, and perhaps arranging established more.
Some principles of the above the utility model stalk check dam that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
