Technical field
A kind of plant state testing device, particularly a kind of plant root absorbs the proving installation of nutrient ability.
Background technology
The plant culture technology is used very extensive in fields such as urban afforestation and fruits and vegetables plantations at present, general cultivated area is all bigger, and can employ great amount of manpower and material resources, if the survival rate of plant of plantation is very low, not only lose plant itself, waste of manpower and material resources, and can influence the afforestation effect of original plan, and may miss the best implantation time of plant, therefore, the plant of cultivation whether survive be very important and crucial.
The factor of the plant cultivated of influence is a lot, environment temperature for example, humidity and the fertile degree of cultivating matrix, the own nutrient absorbing ability of plant etc.Wherein, plant itself is the fundamental influence factor to the nutrient absorbing ability, because if plant itself can't absorb nutrient, even environment temperature is suitable so, preliminary works such as the humidity of cultivation matrix and fertile degree are done very plentifully, and plant also can't be cultivated success.
Most of plant all is to absorb the nutrient of cultivating in the matrix by root, therefore, if can be before plant culture, sampling is earlier tested fast and effectively to the ability that the plant root absorbs nutrient, have under the situation of satisfactory absorption nutrient ability definite plant, carry out large-area cultivation and plantation again, guarantee the survival rate of plant.
Simultaneously, in plant culture research, particularly when research varying environment condition absorbed influencing of nutrient ability to the plant root, the ability that also needs the plant root to be absorbed nutrient was tested.
Whether, generally be by the root of visual inspection plant complete, having does not have more fibrous root, needs judgement person that rich experience is arranged, and judges by accident easily if at present, judging whether the root of plant meets the requirements to the nutrient absorbing ability.And instrument or the equipment that test plant root quickly and efficiently absorbs the ability of nutrient yet appears on the market.
The utility model content
The utility model discloses a kind of proving installation of plant root absorption nutrient ability, be used for solving the instrument of the ability that does not have the nutrient of test plant root absorption quickly and efficiently in the market or the problem of equipment.
A kind of plant root absorbs the proving installation of nutrient ability, comprise the case lid be used to the casing that holds nutrient solution and closed box top mouth, described case lid is provided with the plant implantation hole of some perforations, the bottom of described casing is provided with liquid outlet, the inside of described casing is provided with nozzle, and described liquid outlet is connected with nozzle by the pipeline that has driving pump.
During use, certain nutrient solution is housed in the casing; Plant is fixed on the casing by the plant implantation hole, and wherein root is arranged in the casing, and blade-section is arranged on outside the casing; Driving pump is transported to nozzle with the nutrient solution in the bottom half, by nozzle nutrient solution is sprayed onto the plant root, and the part nutrient solution is absorbed by root, and remaining nutrient solution flows into bottom half.
For the ease of making, to install and cleaning, described plant plantation pilot hole is evenly distributed on the case lid.
For the root of every plant in making nutrient solution that described nozzles spray goes out and being distributed in casing fully contacts, described nozzle is a plurality of.
Preferably, described nozzle has a middle part that is arranged in the casing at least, and at least one is arranged in contiguous cabinet wall place.
Further preferred, the nozzle that contiguous cabinet wall is arranged is three～six, and circumferentially evenly distributes along casing.
Further preferred, all same level heights in nozzle place.
Further preferred, the vertical range of all nozzle distance case lids is 10～60cm.
For the nutrient solution that described nozzles spray is gone out can be full of whole box body, the root of every plant is all fully contacted with nutrient solution, each nozzle has five mouth sprays, and one of them mouth spray arranges that straight up all the other four mouth spray horizontal radiations distribute.
For the ease of making and installing, described driving pump is arranged in the outside of casing.
Also be provided with motorized valve on the described pipeline.
For device can be moved under unmanned situation, also be provided with timing circuit, described motorized valve and driving pump are controlled by this timing circuit.
During use, the root of the plant of needs tests is passed the plant implantation hole, in casing, inject an amount of nutrient solution, by time and the duration that timing circuit set to spray, motorized valve and driving pump are opened in timing circuit control, with nutrient solution from the bottom half sucking-off, and then be transported to each nozzle, nutrient solution by nozzle to around spray nutrient solution, the plant root of periphery is fully contacted, plant root absorption nutrient solution with nutrient solution.Unabsorbed nutrient solution splashes into bottom half, can drive to nozzle by driving pump again and repeat to spray, in the duration of setting so repeatedly, when spray finish after, as long as the surplus of nutrient solution is measured, namely can measure the plant root to the nutrient absorbing ability.
The beneficial effects of the utility model: the utility model uses the casing of a band case lid, by driving pump a certain amount of nutrient solution is transported to nozzle from bottom half repeatedly, in the duration of setting, nozzle sprays nutrient solution repeatedly to the root of the plant of needs test; After spraying end, by measuring the variation of nutrition liquid measure, namely can test out the plant root to the nutrient absorbing ability.
