Abstract
The utility model discloses a deflation ring, which is formed by covering the inner ring and the outer ring together and laying a cloth below for fixing, the inner ring is an opening ring, the outer ring is a closed ring, and the cloth peripheral is extruded and inlayed between the inner and outer rings. The deflation ring has simple structure and easy production. When in use, the deflation ring is inlayed in the soil, the surface is fundamentally equal with the surface, the influence of partial microgeomorphology to the deflation process can be prevented, the bottom cloth has good water permeability and vent ability, the sample in the deflation ring can be held to be consist with the state of the surroundings soil, thus the observation data are reliable and accurate.
Description
Technical field
The utility model relates to a kind of wind erosion circle, refers in particular to the wind erosion circle that is used for field soil wind erosion quantity Quantitative Monitoring.
Background technology
At present, the field soil wind erosion quantity observation procedure that each blown-out land adopts is had nothing in common with each other, the data of being measured can only be reacted the wind erosion trend in a certain area, therefore also lack a kind of monitoring device and method that can compare each blown-out land intensity of wind erosion size, can not be used for unifiedly carrying out the intensity of wind erosion classification and formulating anti-wind erosion measure.Developing a kind of wind erosion circle that is used for open-air quantitative measurement soil drifting amount is highly significant.
The utility model content
The technical problems to be solved in the utility model provides a kind of wind erosion circle, and this wind erosion circle can be placed on the field for a long time because it is simple to operate, carry easily, realizes the quantitative observation of soil drifting.
The technical problems to be solved in the utility model is realized by following scheme: the wind erosion circle, it is characterized in that: the wind erosion circle by two snares in innner and outer together, shop piece of cloth material fixedly forms below, described inner lane is uncovered circle, described outer ring is a closed level, and the periphery extruding of described cloth is embedded in the middle of the circle of innner and outer.
The utility model also comprises following scheme: the diameter of two circles in described innner and outer is 15-25cm, thick 0.3-0.8cm, high 1-3cm.
The utility model has following advantage: this wind erosion coil structures is simple, making is easy.And owing to be embedded in the soil, the surface maintains an equal level mutually with ground substantially, can prevent the influence of local mima type microrelief to the wind erosion process, and cloth permeable aeration in bottom is good, can keep eroding and enclose the consistance of interior soil sample and surrounding soil state, thereby observation data is reliable, accurate.
The measuring principle that wind erosion is enclosed is: realize the soil drifting quantitative determination by the variation of measuring wind erosion front and back soil sample weight, what follow is the minusing principle: it is X with water cut before that the soil drifting in autumn takes place
1An amount of agricultural land soil W that weighs
1After be placed in the wind erosion circle because permeable, the ventilation of the material of wind erosion circle, so soil in this device and land for growing field crops natural soils can form the integral body of a up/down perforation substantially.Substantially no longer will erode after eroding spring in next year the circle in soil fetch its moisture of experimental determination X
2With soil weight in wet base W
2, the difference of twice soil dry weight before and after placing is decided to be the whole wind erosion wind erosion quantity (W) in season, be the wind erosion quantity (W of this mensuration area unit area divided by soil drifting circle area (S) with this wind erosion quantity
f).
Description of drawings
Lift an example below in conjunction with accompanying drawing
Fig. 1 is the three-dimensional view (the innner and outer snare together) of wind erosion circle
Fig. 2 is the inner lane three-dimensional view of wind erosion circle
Fig. 3 is the outer ring three-dimensional view of wind erosion circle
Embodiment
As shown in Figure 1-Figure 3, the wind erosion circle is nested together by two circles 1,2 in innner and outer, and the nylon cloth 3 in shop fixedly forms below, the uncovered circle that inner lane 1 is made for hard PVC material, the closed level that outer ring 2 makes for hard PVC material, the periphery extruding of nylon cloth 3 is embedded in the middle of the innner and outer circle 1,2.The diameter of innner and outer circle 1,2 is 25cm, thick 0.5cm, high 2cm.
As shown in Figure 1-Figure 3, during making, processing earlier makes that lower limb is smooth on the innner and outer circle 1,2 that hard PVC material makes, so that two circles is chimeric.The outside surface of 2 inside surface and inner ring 1 is evenly coated the PVC adhesive glue in the outer ring, again that permeable aeration is good nylon cloth 3 is tiled on the outer ring 2, inner lane 1 is embedded in the outer ring 2 about 90% position from nylon cloth 3 extruding that faces down tightly, remove with icking tool then and expose the unnecessary nylon cloth 3 in outside between two circles, at last with three-piece being embedded in together tightly, and guaranteeing the smooth smooth of upper edge, this has just finished the making of wind erosion circle.
Claims (2)
1. wind erosion is enclosed, and it is characterized in that: erode circle by two snares in innner and outer together, shop piece of cloth material fixedly forms below, and described inner lane is uncovered circle, and described outer ring is a closed level, and the periphery extruding of described cloth is embedded in the innner and outer and encloses middle.
2. wind erosion circle according to claim 1 is characterized in that: the diameter of two circles in described innner and outer is 15-25cm, thick 0.3-0.8cm, high 1-3cm.
