The simulating measurement device can truly reflect the actual water-holding capacity of the shrub grass during the rainfall process, and is simple to operate and convenient to use as well as scientific and reasonable.
Description
Technical field
The utility model has related to a kind of for measuring the simulated measurement device of filling with careless water holding capacity.
Background technology
The mensuration of filling in the past grass water holding capacity adopts field sample prescription collection, indoor soaked, the method for weighing more, calculates the biological water holding capacity of filling with grass layer in vegetation pattern unit area.
In immersion process, sample is heaped-up, is not natural posture, and its water retention characteristic can not reflect actual conditions, and there is some difference with actual water holding capacity, and experimental data can not accurately reflect fills with careless water holding capacity.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of filling simple in structure, easy to use grass water holding simulated measurement device, for the actual water holding capacity of filling with grass is carried out to simulated measurement.
The utility model is achieved through the following technical solutions: the careless water holding simulated measurement device of a kind of filling, on the vertical frame of support by multiple vertical frames and described in being located at, the transverse frame of differing heights forms, grid beam is placed in by cleek on the transverse frame of support, also comprises an artificial rain simulating device and weighs described support and the measuring apparatus of grid beam.
Described measuring apparatus is to be placed in ground balance.
Above described balance, be covered with layer of transparent Polypropylence Sheet.
On the transverse frame of described support bottom, be welded with hollow out frame.
Described hollow out frame frame is on balance.
Described cleek is 4, on surrounding frame each 1.
Described support is hollow shape.
Described grid beam interts into lattice by the iron plate of holding up.
The length, width and height of described support are respectively 0.5m*0.5m*1.1m.
Described artificial rain simulating device is many shower nozzles perforated water spray.
In the utility model, by field sampling, and the distribution situation of grass in sample prescription filled with in record, for the water holding capacity of remover itself is disturbed, before grass is filled with in placement, advanced row rainmaking, make whole device in moist water state, wait not stop precipitation, when balance reading no longer changes, zeroing balance, again according to filling with the distribution situation of grass in sample prescription, the filling grass of same amount is arranged on grid beam according to its actual distribution situation, and utilize tied silk will fill with careless fixed thereon, grid beam is hung on according to actual conditions on the frame of support differing heights, take the now weight of water holding device and sample by title, carry out rainmaking according to different raininess degree again, again take sample and water holding device and sample water holding capacity general assembly (TW), twice weight is subtracted each other and is sample and fills with careless water holding capacity.
From the above mentioned, the utility model can react the actual water holding capacity of filling with grass in Precipitation Process preferably, and this analogue measurement device is simple to operate, easy to use, scientific and reasonable.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Filling grass water holding simulated measurement device as shown in Figure 1, comprise support 1, grid beam 2, many shower nozzles perforated water spray 4 and balance 6, support 1 is made up of multiple vertical frames 8 and the transverse frame 9 of being located at differing heights on vertical frame 8, grid beam 2 is placed in by cleek 3 on the transverse frame 9 of support 1, filling grass is positioned on grid beam 2, fixed by tied silk, measuring apparatus is: be placed in ground balance 6.Balance 6 is covered with layer of transparent Polypropylence Sheet 7 above, on support 1 bottom transverse frame 9, is welded with hollow out frame 5, by hollow out frame 5 by 1, support on balance 6.Cleek 3 is 4, be arranged on surrounding frame, support 1 adopts light material to be made into hollow shape, preferably adopt aluminium alloy to make, the length, width and height of support 1 are set to 0.5m*0.5m*1.1m, if there is lighter material to replace aluminium alloy, the length, width and height of support 1 are preferably 1m*1m*1.1m, the length and width of grid beam 2 should be slightly less than the length and width of support 1, and on support 1, the height of each transverse frame is respectively 20cm from the distance of frame bottom, 30cm, 60cm, 80cm, 110cm, to hang mobilizable grid beam 2.Rainer is the many shower nozzles perforated water spray 4 that is placed in device top.
In actual mechanical process, first by sampling in the wild, choose and this analogue means sample of the same area, take pictures or the distribution situation of the manual filling grass of drawing lower sample prescription in sample prescription, this part is filled with to grass fetches, for the water holding capacity of remover itself is disturbed, before grass is filled with in placement, advanced row rainmaking, make whole device in moist water state, wait not stop precipitation, when balance reading no longer changes, zeroing balance, copy again its actual distribution situation in sample prescription to be arranged on grid beam 2, and utilize tied silk will fill with careless fixed thereon, grid beam 2 can be hung on by cleek 3 on the transverse frame 9 of support 1 differing heights according to filling with careless true altitude, on the transverse frame 9 of support 1 bottom, be welded with hollow out frame 5, by whole device by 5, hollow out frame on balance 6, produce interference and facilitate reading measuring in order to get rid of balance 6 water holdings, on balance 6, be covered with layer of transparent Polypropylence Sheet 7.Take the now weight of water holding device and sample.Rainer is the many shower nozzles perforated water spray 4 that is placed in device top.Select different raininess degree to carry out rainmaking to filling with grass, again take sample and water holding device and sample water holding capacity general assembly (TW), twice weight is subtracted each other and is sample and fills with careless water holding capacity.
Adopt such scheme can relatively truer and reasonably react the actual water holding capacity of filling with grass in Precipitation Process, this filling grass water holding simulating plant operations is simple, easy to use, scientific and reasonable.
