Description
Technical field
The present invention relates to the space coordinate measuring instrument field of stalk or component, specifically a kind of measurement stalk is in soil
The method of spatial distribution in earth.
Background technology
Straw-returning is the important measure for the agricultural sustainable development that current country carries out energetically, and straw-returning mode includes
Mulching and returning, trench digging bury returning to the field and stalk crushing turns over returning to the field etc..Wherein mulching and returning and trench digging, which bury returning to the field, can promote straw
Stalk is packed together, and not only the returning to the field period is longer, and straw decomposition is slower, it is also possible to soil germ be caused to increase.Stalk crushes
Turning over returning to the field can make soil and stalk are fully mixed to bury, and reach preferable decomposition effect, therefore, the mixed degree of burying of stalk and soil is determined
The quality of returning to the field operation is determined, the mixed degree of burying for understanding stalk and soil needs to analyze stalk spatial distribution in the soil, analysis
More detailed, then directiveness is stronger, and the mixed degree of burying of stalk and soil is one and is difficult to the amount observed and measured.So far,
Most-often used method is to obtain the samples-soil of unit area, is divided into upper and lower two layers, and manual cleaning goes out after stalk respectively respectively
Weigh, to obtain the quality of stalk quality and lower soil layer in upper layer of soil, to be further roughly calculated stalk it is upper,
Distribution situation in lower soil.This comparison for calculation methods is coarse, can only simple analysis go out the stalk in upper and lower layer soil
Changes in distribution, can not accurately reflect distributed in three dimensions situation of the stalk in soil space, and accuracy is low, poor reliability, guidance
Property is not strong.
Therefore, it is necessary to a kind of sides that more can accurately and reliably reflect the three dimensional space coordinate of stalk in the soil
Method.
Invention content
The purpose of the present invention is to solve above-mentioned technical problem, provide that a kind of method is simple, accuracy is high, reliability
It is good, distributed in three dimensions situation of the stalk in soil space can be accurately reflected, production cost is low, easily operated measurement stalk is in soil
The method of spatial distribution in earth.
The method that the present invention measures stalk spatial distribution in the soil, includes the following steps:
One, the pedotheque of entire topsoil after straw-returning is completely taken out with sampling groove；
Two, the pedotheque in sampling groove is detected using three-dimensional coordinate measurement device, measures pedotheque respectively

Reason, can position the stalk completely, repeat the above method, and every stalk visible to pedotheque surface both ends carry out successively
It measures and records；
Three, after all stalks for having measured pedotheque surface, topsoil is cleared up, exposes next layer of soil, repeats to walk
Rapid two method, data record；
Four, the method for repeating step 3 is successively cleared up soil, is measured to the stalk both ends in every layer of soil, owns
Data record, until completing the stalk DATA REASONING and record of whole soil layers, these data are depicted as three-D pattern, finally
Obtain the space distribution situation of all stalks in the pedotheque.
Further, it after whole three dimensional space coordinate Value Datas of record being converted into absolute coordinate space, then is compiled into
The acceptable format of three-dimensional graphics software simultaneously inputs in three-dimensional graphics software, you can the space distribution situation of all stalks is presented.
Further, in the step 1, entire topsoil is no more than 20cm.
Further, in the step 3 or four, the thickness of every layer of soil of cleaning is controlled in 10-20mm.
The present invention fetches the pedotheque of entire topsoil using square groove, analyzes it, and utilizes three-dimensional coordinate measurement
Device successively measures the three-dimensional coordinate data at the stalk both ends in soil one by one, and the original of straight line is determined based on two point coordinates
Reason, can position the stalk completely, can be in three-dimensional graphics software after the both ends three-dimensional coordinate data of all stalks is imported
Close to the true distributed in three dimensions situation that stalk is presented in soil space, for more existing measurement method, accuracy and can
It is greatly improved by property, directiveness is strong.
Further, it is contemplated that the reason of returning to the field depth of implements, the thickness of the pedotheque of taking-up is usually no more than 20cm.
