Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
In description of the present utility model, except as otherwise noted, the implication of " multiple " is two or more; Term " on ", orientation or the position relationship of the instruction such as D score, " left side ", " right side ", " interior ", " outward ", " front end ", " rear end ", " head ", " afterbody " be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, construct and operation with specific orientation, therefore can not be interpreted as restriction of the present utility model.In addition, term " first ", " second ", " the 3rd " etc. are only for describing object, and can not be interpreted as instruction or hint relative importance.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " is connected ", " connection " should be interpreted broadly, and for example, can be to be fixedly connected with, and can be also to removably connect, or connects integratedly; Can be mechanical connection, can be also electrical connection; Can be to be directly connected, also can indirectly be connected by intermediary.For the ordinary skill in the art, can concrete condition understand the concrete meaning of above-mentioned term in the utility model.
As shown in Figure 1, a kind of plant cultivation device described in the present embodiment, comprise blake bottle 1, liquid storage bottle 2 and cotton core 3, one end of blake bottle 1 is opening shape, and the other end and liquid storage bottle 2 connect and be tightly connected, can avoid extraneous living contaminants, blake bottle 1 is loaded with matrix, and matrix comprises the medium such as vermiculite, perlite particle, soil, and liquid storage bottle 2 stores nutrient solution, cotton core 3 is arranged between blake bottle 1 and liquid storage bottle 2, the in-built absorbent cotton 5 having in order to fixing cotton core 3 of blake bottle 1.Cotton core 3 is connected matrix with nutrient solution, realize the effect of automatic Additional nutrient solution and water.
Liquid storage bottle 2 can adopt plastic bottle to make, liquid storage bottle cap 4 is housed on liquid storage bottle 2, on liquid storage bottle cap 4, offer a through hole, blake bottle 1 one end is contained in through hole, liquid storage bottle 2 with liquid storage bottle cap 4 for being threaded, blake bottle 1 is provided with adhesive with the junction of liquid storage bottle cap 4, and adhesive is chosen as glass cement, has ensured the seal of this culture apparatus.In order to prevent living contaminants, aseptic breathable sealing film is equipped with in the ringent one end on blake bottle 1.
The bottle shape of blake bottle 1 for standing upside down, can utilize waste and old beer bottle to make blake bottle 1, specific practice is: at the bottom of adopting thermal cutting method to excise waste beer bottle, the cotton thread of a diameter 2-3mm is soaked to full lamp with after alcohol, enclose near the body one of bottom around beer, after fixing, light cotton core with lighter, burn after 1-2 minute, immediately beer bottle is immersed in the water, at the bottom of beer bottle, will fitly come off.The method is Paint Gloss more neat than what cut with glass cutting machine, and can utilize discarded beer bottle to be made into blake bottle 1, has saved production cost.In the unsettled bottomless beer bottle through hole being sitting on liquid storage bottle cap 4, then with glass cement, its junction is carried out bonding, place a couple of days until glass cement completely dry after, make interface by the reality of obturaging.Insert the cotton core of diameter 2cm at beer bottle lower end, regulate cotton core length, make cotton core lower end exceed beer bottle lower end 4cm, make cotton core upper end apart from beer bottle upper end 4cm left and right; And beer bottle lower end is filled up to absorbent cotton, cotton core is fixed and freely do not moved up and down.Finally, liquid storage bottle cap and liquid storage bottle are screwed, obtain this culture apparatus.
The utility model plant cultivation device is in the time testing the functional verification of root system of plant growth-promoting:
The first step pours into the required matrix of plant growth (vermiculite or soil) in blake bottle, controls addition and makes its apogee distance blake bottle upper end 5cm left and right, exceeds 1cm than cotton core upper end; Then, in liquid storage bottle, add plant desired nutritional liquid, culture fluid enters in matrix along cotton core immediately, makes the latter remain moistening; Screw liquid storage bottle cap, then seal the upper end of blake bottle with aseptic breathable sealing film; Then this culture apparatus carries out autoclave sterilization;
Second step, on the superclean bench of the sowing of plant seed after sterilizing, carry out, take off the aseptic breathable sealing film above this culture apparatus of the bacterium of having gone out, by the planting seed of surface sterilizing and presprouting in matrix, again aseptic breathable sealing film is sealed to bottleneck, be put in greenhouse and cultivate;
The 3rd step, sowing plant need grow culture matrix 2-3cm and could inoculate root system of plant growth-promoting bacterium.That is: take off the aseptic breathable sealing film above this plant cultivation device of the bacterium of having gone out, pre-incubated root system of plant growth-promoting bacterium is diluted to after finite concentration, with pipette by bacterial suspension inoculation around root system of plant, then the perlite particle of sterilizing and oven dry is layered on to surface, the about 1cm of thickness, it can avoid the pollution of external miscellaneous bacteria.Then, put back to hot-house culture;
The 4th step, in the time that the nutrient solution in liquid storage bottle runs out soon, need to be to Additional nutrient solution in this culture apparatus, the nutrient solution that is about to prepare carries out sterilizing, and then the liquid storage bottle cap of outwarding winding on the superclean bench of sterilizing, screw liquid storage bottle cap after adding immediately nutrient solution, then put back to hot-house culture.
Functional verification experiment for contaminated soils such as plant-microbe associated bioremediation heavy metals is substantially the same with root system of plant growth-promoting functional verification experiment, only need in plant strain growth matrix vermiculite, sneak into the pollutants such as heavy metal, be configured to after solution by desired concn by pollutants such as heavy metals, be filled in vermiculite, be that vermiculite fully absorbs, but can not too much flow into nutrient solution the inside.
Embodiment of the present utility model provides for example with for the purpose of describing, and is not exhaustively or by the utility model to be limited to disclosed form.Many modifications and variations are apparent for the ordinary skill in the art.Selecting and describing embodiment is for better explanation principle of the present utility model and practical application, thereby and makes those of ordinary skill in the art can understand the utility model design to be suitable for the various embodiment with various amendments of special-purpose.
