Root system has important influence to the growth and development of sugarcane, and the understanding of science is studied and rests in various conditions
The Growth trends and fractions distribution of lower sugarcane root system have important scientific guidance meaning to the development of sugarcane production.
At present, in the world using root system research as a basic research class for further improving production estimation power
Topic, however, since root growth is in underground, accurate sampling is measured, is observed there are certain difficulty, designs a kind of observation sugarcane root
It is that the experimental rig grown is just particularly important research root ecology.Mainly have currently used for the container to root system research
Root case, experiment plastic barrel, hydroponic device etc..Although the research of growth state of plant root system is played centainly using these containers
Effect, still, common potting can get complete root system, but hinder the natural growth and development of root system, easily damage plant
Strain root system.Test cylinder cannot be cut as required, can not obtain the Root morphology in different layerings, limit root system research work
Development.Though what is had can obtain different soil Root morphology but soil may be caused to be scattered when dismantling test cylinder observation root growth,
Soil texture is destroyed, influences root growth, more because its bottom is not provided with controllable permeable hole, be easy to cause ponding.Existing apparatus
It is larger using workload in operation and labor intensity, and the Growth trends of in-situ observation root system entire breeding time are unable to, it influences to grind
Study carefully the reliability and authenticity of result.
Invention content
Against the above deficiency, the utility model provides a kind of device for sugarcane root growth dynamic observation experiment,
It is simple in structure, at low cost, easy to use, operation is flexible, can in situ, the growth and structure of whole observation of plant root system,
Have the characteristics that it is visual, observe at any time, coordinate different tests demand, moisture, heavy metal, salt damage, nutrition, kind, place can be carried out
The growth paired observation of the root systems such as root in the soil.
It is as follows that the utility model solves the technical solution that the technical problem is taken：
A kind of device for sugarcane root growth dynamic observation experiment is docked including at least three layers of same shape and up and down
Connected outer barrel, ring is connected in the outer barrel junction of levels, and the joint of ring uses screw-nut or antithesis
It snaps connection, transparent internal member is placed in the outer barrel, every layer of outer barrel can vertically be divided into two parts and outer barrel has
There is detachable bottom cover.
The internal member is soft bag or stereoplasm tube, and the outer diameter of internal member is less than the internal diameter 0.3-1.5cm of outer barrel.
The outer barrel is round made of nonmetallic materials, height 20-200cm, overall diameter 10-100cm.
The internal member lower part and outer barrel lower part is evenly distributed with permeable hole at cylinder feather edge, and permeable hole is equipped with plug
Son.The a diameter of 0.3-1.0 cm of the permeable hole.
Each outer barrel is equipped with positioning retaining strip in upper edge.
Device disclosed in the utility model has the following advantages that compared with prior art or good effect：
1st, this sugarcane root growth dynamic observation experiment device has simple in structure, at low cost, flexible and convenient to use
Advantage can carry out roots in situ dynamic observation and measure, significantly improve the reliability and authenticity of sugarcane root system research result,
Operation strategies are extensive, have practical and popularizing value.
2nd, ring can ensure the leakproofness between upper and lower test cylinder, in order to which ring is enable to determine when connecting different layers outer barrel
Level is true, using, move, split outer barrel when it is convenient and strength-saving, be fixedly connected with positioning item in the upper edge of every layer of test cylinder,
Not only fixed function is played, but also plays the role of handle and facilitates fractionation.
3rd, internal member can take out at any time, convenient for observation root growth dynamic, while have both and dismantle outer barrel observation root growth
The effect that soil is not scattered during dynamic.Permeable hole can ensure excessive moisture outflow, avoid ponding.
4th, the detachable bottom cover of outer barrel bottom setting so that device facilitates flushing, and repeatable utilization.
5th, in order to ensure sugarcane root system normal growth and in-situ observation, the outer barrel, internal member, ring, positioning retaining strip
And it is fixedly connected with the screw, nut or other accessories of ring and selects existing material, and using conventional technique processing system
Make, easily implement.
6th, this observation experiment device can observe root growth into Mobile state in any period of sugarcane production.Operation
Step：Ring is opened, you can easily open outer barrel observation root growth dynamic, after observation, then outer barrel ring consolidated
It is fixed, it has no effect to root growth.Also it can be needed to take out internal member according to experiment and carry out root system dynamic growth observation, observation
It places into outer barrel after the completion.
7th, it repeats and utilizes, can be layered and obtain complete root system sample, reduce the labor intensity of research work, experiment
Apparatus structure is simple, easy to use, can flexible combination as needed, be to carry out studying preferable utensil for sugarcane root system.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the overlooking the structure diagram of Fig. 1.
