Description
Technical field
The utility model relates to agricultural research technical field, particularly relates to a kind of From The Rhizosphere of Rice soil gathering unit be applicable in cadmium pollution soil analog study.
Background technology
Rhizosphere refers to the impact by root system of plant activity, is different from the part Wei Yutu district of the soil body at physics, chemistry and biology in nature.The scope of rhizosphere is very little, refers generally to from following within several millimeters, axle surface.Many electrochemical conditions of rhizosphere and Biochemical processes are different from soil body soil.It is exactly the most significantly wherein the change etc. of pH in Rhizosphere, redox potential and microbial activity.In rhizosphere soil solution, the distribution of nutrient density and soil body soil have notable difference.Especially in recent years, the research in cadmium pollution paddy rice field, owing to relating to national economy, become agricultural research field problem widely, and wherein, the research of the rhizosphere soil of cadmium pollution paddy rice just seems particularly important.
In order to study the difference of rhizosphere nutrients earth character, people often adopt root bag method analogue means, and the basis of pot experiment is carried out the collection of rhizosphere soil sample.But fresh Rhizosphere sampling has heterogeneity spatially and temporal mutability usually, how pot experiment root bag method analogue means is set accurately and fast and will determines the accuracy of soil testing data, representativeness and comparativity.
At present, pot experiment root bag method analogue means generally adopts the nylon wire in 25 μm of apertures to be sewn into moisture and nutrient can freely pass through and root system impenetrable bag, in-builtly sieve and be mixed with the soil of fertilizer, the seed of rudiment is sown in root bag soil, in the middle of the basin alms bowl again root bag being put into certain volume, in basin alms bowl, load same soil, inside and outside keeping root bag, native face is equal.When after plant growth to certain phase, the soil got in root bag is Rhizosphere Soil, is Non-rhizosphere soil, is dried by soil specimen apart from the soil beyond root bag 25mm, for analysis.But when adopting traditional root bag method analogue means to carry out pot experiment, seed sowing can cause plant strain growth in root bag inconsistent, and the operating process that basin alms bowl directly imbedded by root bag is too loaded down with trivial details, therefore the human error of pot experiment is difficult to control, quite time-consuming when repeat number is more, planting density is larger.
Utility model content
Because described in background technology, the utility model is necessary to provide a kind of root system 360 degree of free growths be both conducive in root bag, is convenient to again pick and place installation, but also is conducive to novel bagging apparatus of the collection of non-rhizosphere soils.
The purpose of this utility model is achieved through the following technical solutions:
Be applicable to the From The Rhizosphere of Rice soil gathering unit in cadmium pollution soil analog study, it comprises: basin alms bowl, multiple bags, root bag hanger and bottom tray; Suitable for reading and the bottom surface of described basin alms bowl is mutually corresponding polygon, and the bottom of described basin alms bowl is provided with multiple air-vent; Described bottom tray is arranged under the bottom of described basin alms bowl; Described in each, multiple bags are cylindrical, and its outer surface adopts polyamide microporous barrier to tighten attaching; The two ends bending of described bag hanger becomes the hook buckled and be located on two relative edges of described basin alms bowl, part between described two ends is located in described basin alms bowl as root bag fixed head to lower recess, the perforate that the radial dimension that described bag fixed head is provided with a multiple and described bag is corresponding, makes described multiple bags be stuck in respectively in described multiple perforate.
Preferably, the suitable for reading and bottom surface of described basin alms bowl is square, and its bottom surface area is slightly less than open area.
Preferably, described bag is cylindrical nylon mesh bag.
Compared with prior art, the utility model possesses following advantage:
Columniform bag can ensure that root system in root bag is towards the free uniform growth of surrounding and bottom, avoids certain direction of root system in bond and causes experimental result to occur deviation; Root bag attaches polyamide microporous barrier outward, can effectively organize thin with and the penetrating of root hair, root system is controlled grow in root bag, but the migration at interlayer of moisture, nutrient, root exudates and edaphon can not be affected; The two ends of root bag hanger hang on described basin alms bowl edge, fixing reliable, pick and place conveniently; Air-vent bottom basin alms bowl is used for the Soil ventilation in basin alms bowl, and via the drip washing liquid of described air-vent seepage, may containing the heavy metal in soil, as cadmium, described liquid can be accepted by described bottom tray, then refunds the accuracy ensureing experimental data in basin alms bowl.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
