Description
Technical field
The present invention relates to soil agrochemistry analysis technical field, specially a kind of centrifugal soil solution extractor.
Background technique
Phosphorus is macronutrient necessary to plant growth, and available phosphorus is the important chemical index of soil fertility, is contained
Amount height directly affects plant growth, and the measuring method of available phosphorus, which has much, to be extracted by certain digestion agent, obtains
Leaching liquor is measured, wherein the development test of soil available phosphorus measuring method, with Olsen method (0.5mol/LNaHCO3Leaching
Mention-molybdenum antimony resistance colorimetric method) it is domestic and international experimental determination neutrality, the universal method of calacareous soil, using Bray method as acid soil
The common method of earth, and up to the present, we can not also really measure the quantity of soil available phosphorus, and commonly called taxi earth has
Phosphorus is imitated, the phosphorus amount being only referred in soil measured by a certain ad hoc approach, therefore, soil available phosphorus does not imply that a certain in scholar's earth
The phosphorus of specific modality, it does not have the concept of real " quantity " yet, so, it can on same soil using different measuring methods
To obtain different available phosphorus quantity, therefore soil available phosphorus level is a relative indicatrix, has system to a certain extent
Meter learns " absolute content " of the meaning without referring in soil " real " available phosphorus.
The soil liquid is that most of soils chemical reaction and soil forming process occur, and is that substance is handed between soil and environment
The carrier changed is the basis of material transport and movement, different from solid phase of soil, and the soil liquid can reflect the true nutrient shape of soil
State, however soil liquid acquisition method mainly uses pot clay end as percolating device both at home and abroad at present, by pot clay end
Chamber applies negative pressure, after filtering the solution in soil by pot clay end, enters in percolating pipe, then again inhales the solution in it
Out, most pot clay ends are strong to the absorption property of phosphorus, and a small amount of non-adsorbent installation cost is high, and to the time required to the extraction of liquid compared with
It is long, and measure smaller, it is difficult to the test of the biggish index of meet demand amount, one as disclosed in Chinese patent CN201610310382.7
The centrifugal centrifuge shield device for extracting the soil liquid of kind, although proposing partial solution, device is cumbersome, and operation is multiple
