Abstract
A portable forecasting ruler for crude protein of an alfalfa grass land comprises a plurality of short rulers, wherein a pin shaft is arranged at the end part of each short ruler; the plurality of short rulers can be sequentially connected in a rotating manner through the pin shafts, so that the forecasting ruler can be folded and unfolded; length scales and crude protein content scales corresponding to the length scales are arranged on the surface of the forecasting ruler; a gasket for preventing the abrasion of each pin shaft is arranged between each pin shaft and each short ruler, and is clung to the surface of each short ruler; the length and width of the plurality of short rulers are the same; and the short rulers are made of stainless steel material. According to the portable forecasting ruler, the operation is convenient, the forecast is precise, and the portable forecasting ruler is suitable for the application of professionals of grassland farming and pratacultural science.
Description
Technical field
The utility model relates to a kind of portable clover meadow crude protein prediction chi.
Background technology
Alfalfa is called as " king of herbage ", has characteristics such as adaptability is strong, rich in protein feeding value height, become cultivation in the world the earliest, one of the widest high-quality legume forage of distribution area.
As good leguminous forage, the bright hay of alfalfa has the protein content height of higher nutritive value, particularly clover.Along with the increase of alfalfa growth and maturity degree, its nutritional labeling can reduce gradually.Outstanding behaviours is in the minimizing of clover blade content, albumen, energy, vitamin and mineral matter element.Particularly clover enters reproductive phase, and after blooming, nutritional labeling descends rapidly, and protein content descends with the speed of every day 0.5%.
For this reason, rationally science is grasped the nutrition variation of clover meadow, is detection and the dynamic change thereof of critical index with the crude protein content particularly, is the main foundation of operation control in the large-scale production of present northern area clover.As the alfalfa of high protein feed, its cultivated area and market are tending towards rapid expansion, press for a kind of quick, easy, accurate test method, in time crude protein content and the dynamic change problem on efficient detection large tracts of land alfalfa meadow.By the administrative time that cradles on prediction or reckoning clover meadow crude protein content and then legitimate inference clover meadow, satisfy the technical need of scale alfalfa industry.
At present, traditional detection method only is only limited to the chemical-agent technique in laboratory, also comprises near infrared not damaged detection means.Because analytic sample quantity is many, test period is long, the first stubble of scale ALFALFA PRODUCTION is cradled to manage cause serious hysteresis.After the laboratory result of a large amount of samples comes out often, the nutrition condition when the alfalfa plants nutrition condition has not been sampling, just crude protein content changes or changes.If according to the long working sample result of time lag--the clover crude protein content is carried out the operation that cradles on scale clover meadow, has not only reduced the waste of clover nutritive value, also certainly will cause the loss of alfalfa industry economy.At present, carry out the clover large tracts of land according to tradition harvest time (initial bloom stage the best) and cradle operation, ignored the correct judgement of clover meadow nutrition condition equally, particularly the understanding of its crude protein content still less simultaneously fails also to consider that alfalfa growing suffers different geography and climate factors to the potential influence of clover meadow crude protein between year.
Therefore, accurate reasonable prediction clover meadow crude protein content cradles the clover meadow in good time, can make clover nutritious, and output is higher, it is the highest to make every effort to reach the total digestible nutrient matter that the unit area soil produces, and makes dairy farmer and plantation can obtain best benefit per family.A kind of portable clover of the present utility model meadow crude protein prediction chi can provide effective decision-making for the decision maker.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model is: provide a kind of portable clover meadow crude protein prediction chi, to solve clover meadow RAPID DETERMINATION OF CONTENT OF COARSE PROTEIN problem.
For this reason, a kind of portable clover of the present utility model meadow crude protein prediction and calculation chi, comprise a plurality of short chis, described short ruler end part is provided with bearing pin, the connection in turn that a plurality of described short chis can rotate by bearing pin, described prediction and calculation chi can be folded or launch, and described prediction and calculation chi surface is provided with the crude protein content scale of length scale and corresponding described length scale.
Wherein, have the pad that prevents described bearing pin wearing and tearing between described bearing pin and the described short chi, described pad is close to described short chi surface.
Wherein, the length of a plurality of described short chis is consistent with width.
Wherein, described short chi adopts stainless steel.
The utility model is easy to operate, accurate.Be fit to ley farming and Practaculture Science professional and technical personnel and use, reached beneficial technical effects.

Embodiment
For shape of the present utility model, structure and characteristics can be understood better, below will enumerate preferred embodiment and also be elaborated by reference to the accompanying drawings.
A kind of portable clover of the present utility model meadow crude protein prediction chi, comprise a plurality of short chis 1, described short chi 1 end is provided with bearing pin 2, and a plurality of described short chis 1 connect in turn by bearing pin 2, make short chi 1 to make the folding or expansion of prediction and calculation chi around these bearing pin 2 rotations.
Have pad between described bearing pin 2 and the short chi 1, this pad is close to short chi 1 surface, can prevent bearing pin 2 wearing and tearing and short chi 1 takes place comes off.The length of each short chi 1 is consistent with width, makes can overlap between the short chi 1 in folding back, with convenient for collecting.Each short chi 1 adopts stainless steel to make, and prevents short chi 1 wearing and tearing and wrecks.
Prediction and calculation chi surface is provided with the length scale, is used for measuring the alfalfa plants height, and is provided with corresponding crude protein content scale, is used for predicting the content of clover meadow clover crude protein.To lack chi 1 during use and launch from folded state, and make short chi 1 end to end formation have the prediction and calculation chi of certain-length, by measuring the height of meadow alfalfa plants, directly read corresponding prediction clover population crude protein content.
The utility model is easy to operate, accurate.Being fit to ley farming and Practaculture Science professional and technical personnel uses.
More than be illustrative to description of the present utility model; and it is nonrestrictive; those skilled in the art is understood, and can carry out many modifications, variation or equivalence to it in spirit that claim limits and scope, but they will fall in the protection domain of the present utility model all.
