Description
Technical field
The utility model is related to a kind of detachable portable farmland weed cover degree survey tools.
Background technology
Farmland weed, is the important component of farmland ecosystem balance, fights for sunlight, nutrient, moisture with crop, sternly
Ghost image rings crop yield and quality, therefore studies stabilization of the Crop-weed Communities for Ensuring Food Safety, the maintenance ecosystem
Etc. all have certain meaning.Weeds coverage is one of the major amount index for studying Crop-weed Communities, farmland weed
Accurate calculate of cover degree is the premise for carrying out Crop-weed Communities analysis.The measurement method of vegetation cover degree includes mainly artificial range estimation
Method, apparatus measures method, remote sensing analysis method and image processing method etc..Mainly estimated at present by artificial ocular estimate, it is difficult
It spends that high error is big, seriously affects the accuracy of result of study；And it is existing measure Weeds coverage instrument and equipment not only price and
Not portable, there is an urgent need for develop plant cover degree survey tool a kind of not only easy to carry but also having certain accuracy.
Invention content
The utility model aim is to overcome the shortcomings of above-mentioned existing method and apparatus, is provided a kind of easy to carry, at low cost
It is honest and clean, can freely assemble, be easy to the detachable portable farmland weed cover degree survey tool promoted and applied in practice.
The utility model includes four angle couplings and the identical four main frame bars of length, twice frame bars and 16
Thin bar.Four main frame bars surround a square frame by four angle couplings, and interval is uniformly distributed on the inside of main frame bar
Identical nine holes are used for interspersed frame bars and thin bar；Two times the mutual cross of frame bars is interspersed, is located at square frame
Center, four ends of secondary frame are inserted into respectively on four main frame bar center holes；16 thin bars are all made of thin wire, every
Thin bar is vertically interspersed between two parallel main frames, and thin bar end is inserted on main frame bar remaining hole, with sub-frame
Main frame is averagely divided into the identical small lattice of square of 100 sizes together, each small lattice area accounts for the 1% of total frame area.
Two-by-two the connection of main frame bar be cassette connection, but hinge connection also can, four main frame bars are connected through the hinge
Constitute square frame.
The plot for needing to investigate can be covered in after being completed according to growth of field plants situation flexible assembling when use
On, the region of certain area is irised out on plot, is counted same weeds (plant) above-ground plant parts in the unit area and is hung down
Total side's number that straight projected area accounts for, the as cover degree of the weeds.If area coverage accounts for the gross area 1%, cover degree counts 1%.This survey
The utilization of amount tool can greatly shorten farmland weed cover degree control time, improve accuracy rate.
The utility model suitable for farmland weed prevent and kill off with agroecological environment, farming measures research weeds,
Plant cover degree is investigated.Folding and unfolding is usually dismantled when not used, is not taken up space, it is easy to carry；When crop field is investigated, assembling is simple, is easy to grasp
Make, the weeds that can be investigated as needed and field crops growing state flexible assembling are easy to use；It counts simple and fast；
Cost of manufacture is cheap；Saving of work and time, a people can be operated completion investigation work, overcome ocular estimate and need the 3-4 talents that can complete
Defect；It measures research with plant, Weeds coverage suitable for all and uses, be easy to promote and apply in practice.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
