Description
Technical field
This utility model relates to a kind of teaching and scientific research and the instrument apparatus of grassland soil degree of packing measurement, is specifically related to a kind of hand-held
Grassland soil degree of packing measuring instrument.
Background technology
Soil evolutionary process and hardness, for a long time by artificial intervention, cause the load of grassland soil day by day to increase the weight of.Meadow is at human intervention
Utilization under, research grassland soil quality evolution Feature there is important effect.
Due to the degree difference of human intervention, soil density has certain difference, especially Regional Sustainable Development of The Qinghai tibet Plateau on spatial and temporal scales
Area accounts for the 26.8% of national total area, brings up 16,000,000 yaks and 50,000,000 and hides sheep, it searches for food on meadow everywhere,
Sleeping breath, migration etc. are trampleed on.Since meadow and domestic animal enforcement home duties are contracted, animal number is gradually increasing, the excessive profit on meadow
Significantly change is there occurs with causing soil quality.Grasp region grassland soil Quality situation, disclose grassland soil physical behavior and develop
And spatial and temporal variation, provide fundamental basis for the accurate animal husbandry of meadow regional development and sustainable Animal husbandry production and there is certain reality meaning
Justice.
Soil density has been widely used for agricultural, gardening and production of forestry, and meadow is produced more and more challenging asking
Topic.Soil compaction causes grassland soil unit weight to increase, and macrovoid reduces, and moisture holding capacity and rate of water infiltration substantially reduce, unfavorable
In plant growing.Soil compaction is the character of soil itself, is also the result that utilization and management process act on generation jointly for a long time.
Soil density is again soil hardness or soil penetration resistance, is made up of Soil Anti shearing, compression stress and frictional force etc., is
One aggregative indicator of resistance of soil.Resistance when general metal plunger or probe press-in soil represents (unit is Pa), refers to
The compacting of soil opposing external force and broken ability, be an aspect of soil property.Additionally, soil physical properties includes soil matter
Ground, structure, porosity etc., relate to the hardness of soil, unit weight, permeability, water-holding capacity, root system of plant penetrate and extend
Difficulty or ease etc..
The big I of soil density affects penetrating and growing of Steppe Plants root system, is an important soil physical property index,
Degenerate for evaluating grassland soil.The soil of consolidation can stop infiltrating of moisture, reduces the utilization rate of liquid manure, soil permeability,
Affect plant root growth, cause primary productibility of grassland to reduce.Occur in that multiple for the testing soil degree of packing in the market
Instrument, but existing instrument is mainly used in the measurement of the agricultural land soil plane degree of packing, to section soil and uneven grassland soil consolidation
Degree cannot be carried out measuring.
Utility model content
Section soil and the defect of the uneven meadow degree of packing, this reality cannot be measured to solve existing soil density measuring instrument
Providing a kind of novel grassland soil degree of packing measuring instrument with novel, it is little that this measuring instrument has volume, simple to operate, easy to carry,
Grassland soil " degree of tightness " degree can be accurately measured.
The purpose of this utility model is to provide a kind of hand-held grassland soil degree of packing measuring instrument, it is characterised in that measuring instrument is by surveying
Bar part, electronic sensor part, handheld terminal forms；Electronic sensor parts are opened by pressure transducer, digital display screen and power knob
Close composition；Handheld terminal is made up of hand holding handle, battery case, lithium battery；Measuring staff part connects pressure transducer top, handheld terminal part
Connect with pressure transducer afterbody.
Further, measuring staff parts include probe and feeler lever；Feeler lever is provided with scale.
Further, handheld terminal afterbody is provided with zeroing switches.
Further, measure bar afterbody and be provided with illuminating lamp.Conveniently work at night and save torch space.
A kind of hand-held grassland soil degree of packing measuring instrument as above, farther includes:
Described probe apparatus senses suffered resistance, by pressure transducer by the grassland soil degree of packing for inserting in soil course
Size shows on digital display screen；
Scale on described feeler lever is for showing that probe inserts the degree of depth of soil.
A kind of hand-held grassland soil degree of packing measuring instrument as above, farther includes:
The lithium battery of described handheld component is mainly used in providing pressure transducer and the electric energy of digital display screen；
Described zeroing switches is for the adjustment of correcting measuring apparatus initial zero degree value.
The beneficial effects of the utility model are: this measurement device precision is high, and simple and compact for structure, volume is little, small and exquisite attractive in appearance, it is simple to
Carry, be especially suitable for field work, not only can be used for measuring for agricultural, gardening and forestry, but also can be used for measuring meadow
The soft or hard degree of plane and the degree of packing of soil profile and dirt band, has good popularizing application prospect.
