Description
Technical field:
The present invention relates to a kind of field portable sampling apparatus and using method thereof, be particularly suitable in the wild power shortage time, for extracting leaching water and runoff water in the nitrogen phosphorus observation process of farmland, belong to agricultural equipment technical field.
Background technology:
Along with people are to the growing interest of agro-environment safety, particularly consider that farmland nitrogen phosphorus leaching loss of nutrient and runoff loss are on the impact of body eutrophication, increasing research now concentrates in the pollution of area source problem of farmland fertilizer.Set up at present long-term tillage monitoring device mainly in-situ soil leaching solution collector and the footpath flow liquid collecting pit of nitrogen phosphorus leaching loss and runoff loss in field, a kind of simple runoff collecting device disclosed in a kind of farmland underground eluviation in-situ monitoring device and Chinese patent CN101915684 disclosed in Chinese patent CN101246156.In-situ monitoring device or runoff collecting device are all arranged on underground, its principle is all that leaching liquor or footpath flow liquid are collected in fixing container, and then Liquid extracting out, analytical test concentration of nitrogen and phosphorus, again in conjunction with the volume of leaching loss liquid or footpath flow liquid, and then calculate the loss amount of nitrogen phosphorus.
In research farmland nitrogen phosphorus nutrient loss process, how to extract footpath flow liquid and leaching liquor be at present faced by a great difficult problem.How under field lacks electric energy and other mechanokinetic situation, runoff water being sucked out at the bottom of runoff pond or leaching water is drawn out from gathering-device, is all a troubling problem.Still there is no suitable draw-out device at present.A lot of seminar this work has used mostly medically conventional foot-operated attractor carrying out, and with helping water intaking, but this instrument is medically mainly used in helping patient phlegm-suction, and the amount of liquid of absorption is little, generally can not more than the volume of 1 liter; Although can be used in field collecting the leaching water (volume of leaching water is relatively less) of experimental plot, poor effect; If larger trouble will be run into when collecting the runoff water of experimental plot with this foot-operated attractor, because the gatherer volume of footpad suction unit only has 1L, and the footpath flowing liquid that each experimental plot is collected long-pending be generally several several decaliters that rise to, when being used for extracting runoff water after filling gatherer, dry gatherer is needed again to extract again, tens of times of repeatable operation like this, time-consuming, efficiency is lower.
At present, along with the requirement of people to living standard judicial convenience degree is more and more higher, direct current Portable water pump has more and more been subject to the favor of people.But general DC water pump all needs now to connect the outer power supply source of direct current, and the operation controlling water pump needs by disconnecting and the connecting line that switches on power, not only not portable, and operation is also extremely inconvenient, in addition, very inconvenient to direct supply charging.
Summary of the invention:
For the deficiencies in the prior art, the invention provides a kind of field portable sampling apparatus and using method thereof, solution collection room and water pump are set together, easy to carry, greatly meet the extraction needs of farmland nitrogen phosphorus monitoring central diameter flow liquid and leaching liquor.
Technical scheme of the present invention is as follows:
