Abstract
The invention discloses a soil sample linearly collecting method and a soil sampling device. The method includes preparing the soil sampling device; determining a soil sampling route; arranging a plurality of soil sampling positions; determining a sampling route on the soil surface at each of the soil sampling positions, and then collecting downward a soil sample of a section according to the sampling route to obtain a soil sample of each of the soil sampling positions; and mixing uniformly the soil samples of the soil sampling positions to obtain a soil sample of the whole farmland. The soil sampling device used for linearly collecting the soil samples comprises a soil sampling shell and a soil sampling head, wherein the soil sampling shell comprises a soil outlet disposed at a side of the soil sampling shell and moving wheels disposed at the bottom of the soil sampling shell, and the soil sampling head is disposed in the soil sampling shell. Because of difference of soil characteristics between crop rows and difference of soil characteristics at different distances in the crop rows, soil sampling methods at present have a disadvantage of bad soil sample representativeness. The method and the soil sampling device provided by the invention effectively solve the problem of the bad soil sample representativeness, and provide soil samples with high representativeness for detection of various soil indicators.
Description
Technical field
The present invention relates to gather pedotheque technical field, particularly relate to the method for line acquisition pedotheque, and for the drawing out soil equipment of line acquisition pedotheque, realize and from farmland, gather representative pedotheque.
Background technology
In prior art, in order to know various physical features and the chemical feature of soil, need to gather pedotheque, especially, for the demand of farmland Tree Precise Fertilization and Precision Irrigation, need representative higher pedotheque.Objective circumstances are, whole soil layers in farmland can not be taken out, and sample after mixing soil again, therefore can only spot sampling.When prior art farmland samples, in farmland along certain route (such as serpentine or " Z " shape etc.), arrange several sampling spots, by earth boring auger or other instruments, at each sampling spot, get the earth pillar of certain depth, 5～10 centimetres of the diameters of earth pillar, by the soil of gross sample point both mix must this farmland soil sample.The defect of existing sampling technique is that the diameter of each point only has 5～10 centimetres of left and right, and the intrinsic inhomogeneity of agricultural land soil and due to the artificial measure of cultivating, make soil in part, have larger difference, between crop row and crop row, also have and crop row different distance place, the characteristic of soil is discrepant, even if use the mode of farmland ploughing, can not eliminate this otherness, thereby this soil sample of getting by point at each sampling spot can not represent this some larger area soil characteristic around, thereby use this farmland sample obtaining by point sampling, its representativeness is not strong, be necessary to improve sampling method and drawing out soil equipment.
It is pointed out that the above-mentioned sampling method fetching earth by point has become a kind of technology prejudice.
Summary of the invention
The object of the invention is to propose a kind of method of line acquisition pedotheque, the representative poor problem of soil sample gathering to solve existing soil basketing method.The present invention also provides the drawing out soil equipment of line acquisition pedotheque, to realize above-mentioned soil basketing method.
In order to solve the problems of the technologies described above, the present invention has adopted following technical scheme: a kind of method of line acquisition pedotheque, and it comprises the following steps:
The first step, prepares drawing out soil equipment;
Second step, determines the route that fetches earth;
The 3rd step, arranges that several fetch earth a little;
The 4th step, fetches earth a little at each, first at soil surface, determines sample line, then presses the sample line soil sample of a section of collection downwards, obtains this soil sample that fetches earth;
The 5th place, the soil sample that each is fetched earth a little mixes, and obtains monoblock field soil sample.
Further, sample line described in the 4th step is perpendicular to crop row or ploughing direction.
Further, sample line described in the 4th step is at least continuously through between a crop row and a crop row.
