Abstract
The utility model relates to an excretion collecting device for root system of plant, include the cultivation bucket that is used for holding the culture solution, cultivation barrel top portion is provided with and is used for keeping the top cap of plant roots submergence in the culture solution, be provided with the trachea of external air pump in the cultivation bucket, releasable connection has the resin post that is used for adsorbing plant roots secretion in training the bucket. The utility model has advantages of simple and reasonable structure design, the simple operation is through resin column adsorption plant roots secretion, the trachea lets in the gas of culture solution and guarantees not only that plant roots breathes required oxygen, can also make the culture solution constantly flow, realizes that the circulation of live body plant roots secretion is collected, and the enrichment volume of plant roots secretion is big, easily analysis.
Description
Technical field
The utility model relates to a kind of excretion collecting device for root system of plant.
Background technology
Root exudates broadly refers in Root-development the whole organic substances be discharged in medium, but sometimes narrow finger enters the dissolved organic matter in soil by exudation effect.Sensu lato root exudates mainly comprises following 4 types: (1) exudate: for by the low-molecular-weight compound of a class diffused out passively in cell.(2) secretion: the material initiatively discharged due to metabolic process cell.(3) baregin: comprise Root cap cellll, do not form the sticky colloid substance of the epidermal cell of secondary wall and Gen Mao secretion.(4) decomposition and cast: matured root segment table chrotoplast selfdecomposition product, the Root cap cellll that comes off, Gen Mao and cell fragment.
Root secretion composition and the change of content be plant responding environment-stress the most directly, the most significantly react.It is the result that different ecological type plant adapts to for a long time to its living environment, and specificity root secretion, as an important inhereditary feature, has been subject to the pay attention to day by day of people in plant nutrient heredity improvement.In plant normal growth growth course, the organic substance that the metabolic exudation of root goes out is general root secretion, they are Secondary metabolites mostly, are the results of a series of physiological and biochemical procedure combined action of plant, and the minor gene probably showing as quantitative inheritance character controls.Visible, the collection of secretions from plant roots is the important foundation analyzing and study plant genetic and physiological property with analyzing.
Utility model content
In view of the deficiencies in the prior art, technical problem to be solved in the utility model is to provide the excretion collecting device for root system of plant of a kind of reasonable in design, simple operation.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of excretion collecting device for root system of plant, comprise the cultivation bucket holding nutrient solution, described cultivation bucket top is provided with to keep root system of plant to be immersed in top cover in nutrient solution, be provided with the tracheae of external air pump in described cultivation bucket, in described cultivation bucket, releasable connection has the resin column adsorbing secretions from plant roots.
Preferably, described top cover offers some through holes passed in order to root system of plant.
Preferably, described tracheae is Y-shaped, and the two ends of described tracheae are stretched in the nutrient solution cultivated in bucket, the middle part of described tracheae is connected with air pump, and the two ends of described tracheae are furnished with some gas outlets.
Preferably, the two ends of described tracheae are fixed on the bucket wall of cultivation bucket through set collar.
Preferably, described cultivation bucket has dismountable bottom, and described resin column releasable connection is on bottom.
Compared with prior art, the utility model has following beneficial effect: the utility model structural design is simple, rationally, simple operation, adsorbs secretions from plant roots by resin column; The gas that tracheae passes into nutrient solution not only ensure root system of plant breathe needed for oxygen, nutrient solution can also be made constantly to flow, realize the circulating collection of live plant root exudates, the enriching quantity of secretions from plant roots is large, is easy to analyze.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Accompanying drawing explanation
Fig. 1 is the organigram of the utility model embodiment.
In figure: 1-cultivates bucket, 11-bottom, 2-top cover, 21-through hole, 3-air pump, 4-tracheae, 41-gas outlet, 5-resin column, 6-set collar.
Embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
As shown in Figure 1, a kind of excretion collecting device for root system of plant, comprise the cultivation bucket 1 holding nutrient solution, described cultivation bucket 1 top is provided with to keep root system of plant to be immersed in top cover 2 in nutrient solution, preferably, described top cover 2 is tangent with nutrient solution liquid level, and be provided with the tracheae 4 of external air pump 3 in described cultivation bucket 1, in described cultivation bucket 1, releasable connection has the resin column 5 adsorbing secretions from plant roots.
In the utility model embodiment, described top cover 2 offers some through holes 21 passed in order to root system of plant, the above position of described root system of plant is above top cover 2.
In the utility model embodiment, described tracheae 4 is Y-shaped, and the two ends of described tracheae 4 are stretched in the nutrient solution cultivated in bucket 1, the middle part of described tracheae 4 is connected with air pump 3, and the two ends of described tracheae 4 are furnished with some gas outlets 41.
In the utility model embodiment, the two ends of described tracheae 4 are fixed on the bucket wall of cultivation bucket 1 through set collar 6.
In the utility model embodiment, described cultivation bucket 1 has dismountable bottom 11, and the releasable connection of described resin column 5 is on bottom 11.
The utility model is not limited to above-mentioned preferred forms, and anyone can draw other various forms of excretion collecting device for root system of plants under enlightenment of the present utility model.All equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
