Whether the plant is cultivated by the water or the soil, the device comprises a plant cultivating part and a root secretion collecting part. The plant is cultivated in a cultivating barrel, and the water flows to the tapered plastic bottom of the cultivating barrel by means of the filtration of a filtering plate, enters a hose through a thick conduit and a water valve by means of the filtration of a coarse-hole filtering mesh, passes through a resin pipe under the function of a peristaltic pump, and reflows into the cultivating barrel through the conduit and the U-shaped conduit by the means that the root secretion of the plant is absorbed by the special resin. The device has the characteristics of being simple in structure, small in floor area and low in cost, and is suitable for water cultivation and soil cultivation, high in collecting efficiency, high in practical applicability, and wide in promotional value.
Description
Technical field
The utility model relates to a kind of harvester, particularly under water planting and earth culture condition, and a kind of harvester of secretions from plant roots.
Background technology
In growing process, root system is as the contact portion of plant and soil, its secreting phenomenon is a kind of normal, positive physiological function of plants, root exudates is between the plant, between plant and the microorganism in order to meet competition or symbiosis etc. and a kind of chemical substance of secretion.Root exudates is under certain condition, the general name of living, be not discharged into the organic substance in the rhizospheric environment by undisturbed root system.It is the key factor that keeps rhizosphere microecosystem vigor, also is the important component part that material moves and regulates in the rhizosphere microorganism system.
In recent years, in order to inquire into plant competition mechanism, biotic intrusion principle, allelopathy is widely studied.Under natural situation, mainly enter soil behind the synthetic allelochemical of plant: 1. discharge volatilization, misty rain leaching in addition by plant by 3 kinds of approach; 2. by the root system direct secretion; 3. the decomposition by the plant residue or the thing that withers and falls.Root system of plant is the important channel that allelochemical enters environment, and the root exudates kind is more, comprises three major types: the first kind is a larger molecular organics, and second class is a small organic molecule, and the 3rd class is growth hormone, flavones and steroid class etc.Existing studies show that, the phenol acid substance in the root exudates, having sense effect, therefore the Collection and analysis of specific root exudates just becomes necessary, and this has also just proposed requirement to the gathering-device of secretions from plant roots.The gathering-device of traditional secretions from plant roots, structure are complicated, and floor area is bigger, are difficult to promote; Water planting and earth culture can not intersect use besides, and practicality is not strong.
Summary of the invention
The purpose of this utility model is in order to solve above-mentioned problems of the prior art, a kind of harvester of secretions from plant roots is provided, characteristics simple in structure, that floor area is little and cost is low that this device has, both be fit to the collection that water planting also is fit to the secretions from plant roots of earth culture, the collection efficiency height, practical.
The utility model is achieved through the following technical solutions:
A kind of harvester of secretions from plant roots comprises that plant is cultivated part and root exudates is collected part, and plant cultivation part comprises cultivates bucket, filter, conical lower section, gross porosity screen pack, thick conduit, water valve, bracing frame, the first conversion joint, following geometrical clamp, last geometrical clamp; Support frame as described above is supported on described cultivation bucket on the estrade, and described bottom of cultivating bucket is equipped with described filter, and its diameter is identical with the internal diameter of described cultivation bucket, and the small aperture on the described filter is 2-5mm; The center connects described thick conduit at the bottom of the described conical plastic, and described thick catheter tip is placed the described gross porosity screen pack of one deck, and the aperture of described gross porosity screen pack is 0.2-1.0mm; Described water valve is installed at the middle part of described thick conduit, and the bottom connects the first conversion joint, and described geometrical clamp down, last geometrical clamp are welded on the described cultivation bucket, and fixedly root exudates is collected part.
Root exudates collection unit branch comprises the second conversion joint, following rotation standing valve, following screen pack, pitch tube, last screen pack, on rotate standing valve, conduit, U type pipe; Direction according to current, the described second conversion joint connects described rotation standing valve down, and described rotation standing valve down connects described pitch tube bottom, and described screen pack is down laid in described pitch tube lower end, the described screen pack of going up is laid in the upper end, and the aperture of two screen packs is less than the particle diameter of corresponding resin; The top of described pitch tube connects the described rotation standing valve of going up, and the described rotation standing valve of going up connects described conduit, and described conduit connects described U type pipe, and the water delivering orifice of described U type pipe is over against described cultivation bucket.
Plant is cultivated part and is connected by flexible pipe with root exudates collection part, and flexible pipe one end connects the first conversion joint that plant is cultivated part, and other end connection root exudates is collected the second conversion joint of part, and peristaltic pump is installed on the flexible pipe.
For the earth culture plant, plant cultivation part also is included in and lays one deck thickness on the described gross porosity screen pack is the silica sand of 5-10cm, the particle diameter of silica sand is 0.2-1.0mm, silica sand upper berth thin film, be generally PVC film or PE film, on film, place described filter, make it stressed evenly, on described filter, move into the soil of effective dose.
Because the geopetal of root system of plant, the growth of root system can be passed filter, penetrates film.Open valve, rely on water body gravity that water is flowed from top to bottom, open peristaltic pump, make water from the bottom up,, be back to and cultivate in the bucket, realize the circulation of water body through pitch tube.Root exudates is just realized circulation, collects the root exudates that plant secretion goes out by specific resin, reaches the purpose of collection.Described specific resin comprises Amberlite zero R XAD-4 resin, HPD-400 type macroporous absorbent resin and the XAD-16 macroreticular resin that mixes with any proportioning.
The utility model has following outstanding essential characteristics and remarkable advantage compared with the prior art:
This harvester volume is less, and is simple in structure, and application suits large area to popularize.Increase filter, screen pack and film by design, can effectively prevent line clogging, and resin runs off.What the utility model used is peristaltic pump, needn't worry because the deficiency of current causes water pump and finds time and break down.This device both had been fit to the hydroponic plant root exudates and had collected the collection that also is fit to secretion from root system of plant in pot, and the scope of application is wider.The utility model can be realized the enrichment to root exudates by the continuous water cycle of peristaltic pump, and can pass through the flow velocity of the water of change peristaltic pump, improves the rate of circulation of water, and then has increased the recovery of root exudates.
