Abstract
The utility model discloses a plain drip washing collection device of phosphorus in research soil profile. It includes that the end is conical container, and the sand grain metalling has been put to the container lower part, and end department of the toper portion of container is equipped with the leachate collecting vat, and its cell wall is equipped with many infiltration holes, takes over on the leachate collecting vat and says, the upper end opening of pipeline still is equipped with the water pump outside stretching out the container, and the inlet tube of water pump passes during the pipeline stretches into the leachate collecting vat, still is equipped with the leaky pipe that has the switch on the cell wall of leachate collecting vat lower part. Utilize the utility model discloses a plain drip washing collection device of phosphorus in research soil profile can convenient and fast the soil profile carries out and in the plain drip washing of phosphorus experimental, collect the leachate and be used for the experimental study to for the plain research condition of providing convenience of phosphorus in the soil profile.
Description
Technical field:
The utility model belongs to soil investigation clothing arts, is specifically related to phosphorus element drip washing gathering-device in a kind of research soil profile.
Background technology:
Phosphorus is as one of large element of plant growth necessary 3.The accumulation of soil phosphorus can improve the deliverability of soil phophorus, be high crop yield high-quality improve material base, but phosphorus accumulation exceed certain limit will to water body environment produce harm.
The phenomenon of current China excessive fertilization is very general, and the plain excessive problem of phosphorus is comparatively outstanding.In agricultural production, because the industrial crops planting benefits such as veterinary antibiotics are high, peasant habit is in a large amount of excessive manure use and chemical fertilizer, result causes a large amount of accumulations of Phosphorus in Soil, be accumulated in the growth needs that the phosphorus in soil cannot meet general crop because it is poorly soluble on the one hand, on the other hand by agricultural drain, the modes such as rainwash enter water body, harm environment.Therefore study P bioavailability and the storage capacity thereof of soil, have important effect to agricultural production and environmental evaluation.
Summary of the invention:
The purpose of this utility model is to provide phosphorus element drip washing gathering-device in a kind of research soil profile.
The utility model is implemented by the following technical programs:
Phosphorus element drip washing gathering-device in research soil profile of the present utility model, it is characterized in that, comprise the container that the end is taper, lower vessel portion is placed with sand grains metalling, and the tapered portion bottom position of container is provided with leacheate feeder, its cell wall is provided with many water seepage holes, leacheate feeder upper connecting tube road, outside the upper end open propelling container of pipeline, is also provided with water pump, the water inlet pipe of water pump stretches in leacheate feeder through pipeline, leacheate feeder bottom cell wall is also provided with the leaky pipe with switch.
Described pipeline is preferably PVC pipeline.
In research soil profile of the present utility model, phosphorus element drip washing gathering-device uses like this: on sand grains metalling, stack soil to be studied, then grown on soil crop, as tomato, when carrying out washing tests, use leacheate washed off soil, phosphorus element is just dissolved in leacheate, sand grains metalling is leaked out to leacheate, entered in leacheate feeder by water seepage hole again, then open water pump, the leacheate with phosphorus element is pumped and studies.Do not take out to the greatest extent or unwanted leacheate discharged by leaky pipe.
Utilize phosphorus element drip washing gathering-device in research soil profile of the present utility model conveniently can carry out phosphorus element washing tests in soil profile, collect leacheate for experimental study, thus study for phosphorus in soil profile is plain condition of providing convenience.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of phosphorus element drip washing gathering-device in research soil profile of the present utility model;
Wherein 1, container; 2, sand grains metalling; 3, leacheate feeder; 4, PVC pipeline; 5, water pump; 6, leaky pipe; 7, soil.
Embodiment:
Embodiment 1:
As shown in Figure 1, phosphorus element drip washing gathering-device in the research soil profile of the present embodiment, comprise the container 1 that the end is taper, this container can be made with concrete, lower vessel portion is placed with sand grains metalling 2, soil 7 to be studied can be placed above sand grains metalling 2, the tapered portion bottom position of container is provided with leacheate feeder 3, its cell wall is provided with many water seepage holes, leacheate feeder connects PVC pipeline 4, outside the upper end open propelling container of PVC pipeline, also be provided with water pump 5, the water inlet pipe of water pump stretches in leacheate feeder through PVC pipeline, leacheate feeder bottom cell wall is also provided with the leaky pipe 6 with switch.
