Abstract
The utility model belongs to the technical field of soil salinity indicating devices, and discloses a soil salinity leaching indicating device. The essential technical characteristics are as follows: the soil salinity leaching indicating device comprises a supporting pipe for being inserted into soil, wherein a filtrate inlet is arranged on the supporting pipe, and a filter screen is arranged on the filtrate inlet; and a salinity probe is arranged near the filtrate inlet and is connected with a display device positioned at the outer side of the supporting pipe. In the leaching process of soil salinity, water in soil passes through the filter screen and the filtrate inlet and flows into the supporting pipe, and the salinity content of the inflowing water can be measured by the salinity probe positioned near the filtrate inlet in the supporting pipe and can be displayed by the display device; the measured soil salinity content is based on to decide whether the leaching is stopped or not, accordingly, not only the effective leaching of the soil salinity is achieved, but also the water source can not be wasted, the monitoring is convenient, the monitoring data is accurate, the tedious calculation is not needed, and the manpower is saved.
Description
Technical field
The utility model belongs to soil salt indicating device technical field, relates in particular to a kind of soil salt drip washing indicating device.
Background technology
Soil salt drip washing is a top important technology content during alkaline land improvement and irrigation with saline water utilize, irrigating wash out amount is the key of soil salt drip washing, the too for a short time drip washing target that needs that do not reach of wash out amount, can work the mischief to crop and soil, the too big drip washing of wash out amount is effective, but causes water resource and energy dissipation.Wash out amount is irrigated in Calculation Method estimation at present commonly used, but on calculating, there are many problems, because it is very complicated that the factor of drip washing effect is irrigated in influence, comprise soil salt content, be used for the salinity, the soil texture, soil body configuration, initial soil moisture content of the irrigation water of drip washing etc.Many simplification computing formula are omitted the soil texture, soil body configuration, soil moisture content etc., and result of calculation is inaccurate.The calculating that Consideration is many is impracticable aborning.Utilize the method for soil salt monitoring to determine to irrigate wash out amount accuracy height.But adopt the conventional at present monitoring soil salt method that fetches earth infeasible in irrigating in real time.Adopt TDR probe cost very high again.
The utility model content
The technical matters that the utility model solves just provide a kind of easy to use, can monitor soil salt drip washing situation in real time and according to the soil salt drip washing indicating device of resulting numerical value decision whether stopping drip washing.
For solving the problems of the technologies described above, the technical scheme that the utility model soil salt drip washing indicating device adopts is: comprise the stay pipe that is used for inserting in the soil, described stay pipe is provided with the filtrate import, described filtrate import is provided with filter screen, be provided with the salt sub-probe near near the described filtrate import, described salt sub-probe is connected with the display device that is positioned at the described stay pipe outside.
Its additional technical feature is:
Described filtrate import is the fillter section that is positioned at described stay pipe lower end;
Described filtrate import is the filtering holes that is positioned at described stay pipe side, stay pipe inboard in described filtering holes lower end is provided with the filtrate baffle plate, described filtrate baffle plate and described stay pipe inwall surround the probe chamber of upper end open, and described salt sub-probe inserts in this probe chamber;
The degree of depth in described probe chamber is more than or equal to the length of salt sub-probe.
Soil salt drip washing indicating device provided by the utility model compared with prior art has the following advantages: one, owing to comprise the stay pipe that is used for inserting in the soil, described stay pipe is provided with the filtrate import, described filtrate import is provided with filter screen, be provided with the salt sub-probe near near the described filtrate import, described salt sub-probe is connected with the display device that is positioned at the described stay pipe outside, in carrying out the soil salt lessivation, water in the soil enters in the stay pipe through filter screen and filtrate import, be positioned at the salt content that near the salt sub-probe of stay pipe filtrate import can record the water that flows to, and show by display device, according to the soil salt content that records, whether decision stops drip washing, like this, not only reach the purpose of effective washed off soil salinity, the water source of can also avoiding waste, and monitoring is convenient, and Monitoring Data is accurate, do not need troublesome calculation, saved manpower; They are two years old, because described filtrate import is the filtering holes that is positioned at described stay pipe side, stay pipe inboard in described filtering holes lower end is provided with the filtrate baffle plate, described filtrate baffle plate and described stay pipe inwall surround the probe chamber of upper end open, described salt sub-probe inserts in this probe chamber, irrigation water enters in the probe chamber through filter screen and filtering holes, when the irrigation water height in the probe chamber surpasses the filtrate baffle plate, irrigation water flows in the stay pipe through filtrate baffle plate upper end, make the irrigation water that in observation process, flows in the stay pipe seldom, like this, the water that stores in the probe chamber is identical with the salt content of water in the soil all the time, prevent the many and overlong time of the water that flows into to stay pipe, flow into the salinity height of irrigation water in the incipient stage, the problem that the salt content that causes measuring is higher than actual value takes place; Its three because the degree of depth in described probe chamber like this, can guarantee under the complete immersed in liquid level of salt sub-probe more than or equal to the length of salt sub-probe, make measure more accurate.
Description of drawings
