Abstract
The utility model discloses a soil nutrient in-situ extraction instrument, which comprises an ion exchange resin module and a test instrument used for loading the ion exchange resin module, wherein one end of the test instrument is provided with a clamp groove, and the ion exchange resin module is fastened in the clamp groove through a fixing element matched with the clamp groove. The soil nutrient in-situ extraction instrument has the advantages that the structure is simple, the realization is easy, the ion exchange resin module is fixedly arranged in the clamp groove of the test instrument and is positioned at a through hole part of the test instrument, the adsorption function of the ion exchange resin module is not influenced, in addition, one end of the test instrument is provided with a sharp opening, the device can be easily inserted and fixed in any position of a plowing layer under the condition without stirring a soil body, and the operation is simple and convenient.
Description
Technical field
The utility model relates to a kind of extraction apparatus, relates in particular to a kind of soil nutrient in-situ extraction instrument.
Background technology
The survey soil formula technique that adopts on the agricultural, the general chemical method soil testing of adopting routine.This soil testing technology adopts field sampling, room-dry, weighs, chemical method is extracted, measure supervisor, and both time and effort consuming, cycle were long, has changed again the field situation of soil nutrient.Because traditional conventional soil testing adopts chemical reagent to extract soil nutrient, the mechanism that absorbs nutrient with root system of plant is made a world of difference, can only measure the content of nutrient in the soil, but can't truly characterize soil nutrient to the effective status of plant, the fertilizer recommendations take conventional soil testing as foundation does not often meet crop to the actual needs of nutrient very much.And measuring the same nutrient in different regions often needs with different method of testings, and acquired results is difficult to mutual comparison.
For the problems referred to above, the ion-exchange-resin process soil testing that development in recent years is got up is widely adopted in North America and South America, and the research report of fragmentary this method of use is also arranged in China.Compare with traditional chemical method soil testing, ion-exchange-resin process has very large superiority.Because ion-exchange-resin process is to come the testing soil nutrient to the effective supply of plant by ion exchange, similar to the absorption mechanism of nutrient with plant, with plant the absorption of nutrient is had good fitness.The fertilizer recommendations of having done according to this method test result comes rationally than the scheme that classic method proposes.Particularly adopt the mixed type anion-cation exchange resin, once can extract simultaneously the various Different Nutrients that plants needs.This method has been exempted loaded down with trivial details pedotheque preparation and chemical extraction step, and is easy and simple to handle, the time and labour saving, and with low cost, cost only has the 20-30% of conventional method.Yet nowadays the method is only applicable to the experimental determination of soil nutrient, as measuring the nutrient of field original position, also need be equipped with suitable support equipment.
The utility model content
The purpose of this utility model is for the problems referred to above, and a kind of soil nutrient in-situ extraction instrument is provided, and it has simple in structure, is easy to realize the characteristics that the mensuration process is convenient and reliable.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of soil nutrient in-situ extraction instrument, comprise the ion exchange resin module and be used for loading the tester of this ion exchange resin module, one end of described tester has through hole, the two ends of described through hole are provided with draw-in groove, and described ion exchange resin module is anchored in the draw-in groove by the fixture that is complementary with described draw-in groove.
Further, described ion exchange resin module is flat structure.
Further, the described tester end that has through hole one end is provided with sharp-crested.
Further, described sharp-crested is triangular structure.
Further, be provided with fin or the groove that indicates metering scale on the outside surface of described tester.
Further, described tester is made of plastics.
Further, described draw-in groove and fixture are the intercalation structure, and described fixture is the L-type structure, and it is intercalated in the draw-in groove.
The beneficial effects of the utility model are, described soil nutrient in-situ extraction instrument is simple in structure, be easy to realize, it is fixed in the ion exchange resin module in the draw-in groove of tester, the ion exchange resin module is positioned at the through hole of tester, do not affect the adsorption function of ion exchange resin module, and tester one end is provided with sharp-crested, can be in the situation that do not stir the soil body, easily this is installed insertion and is fixed in any position of arable layer, simple, convenient.

Embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.
Please refer to shown in Fig. 1 to 3, in the present embodiment, a kind of soil nutrient in-situ extraction instrument, comprise ion exchange resin module 1 and be used for loading the tester of this ion exchange resin module 1, described ion exchange resin module 1 is flat structure, described tester is made of plastics, be provided with the fin 4 that indicates metering scale on the outside surface of tester, the one end has through hole, described through hole two ends are provided with draw-in groove, and the end that tester has through hole one end is provided with sharp-crested 3, described sharp-crested 3 is triangular structure, and described ion exchange resin module 1 is anchored in the draw-in groove by the fixture 2 that is complementary with described draw-in groove, and described draw-in groove and fixture 2 are the intercalation structure, described fixture 2 is the L-type structure, and it is intercalated in the draw-in groove.
During assembling, only need ion exchange resin module 1 is inserted in the draw-in groove of tester, and fastening with fixture 2, during use, the end that tester is provided with sharp-crested 3 is down, insertion also is fixed in any position of arable layer, the fin 4 that plays the sign metering scale that arranges on the tester outside surface can be known to reflect that soil nutrient in-situ extraction instrument inserts the degree of depth of arable layer, and is easy and simple to handle, the time and labour saving, and economical and practical.
Above embodiment has just set forth ultimate principle of the present utility model and characteristic; the utility model is not limited by above-described embodiment; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
