Abstract
The invention discloses a soil nutrient in-situ extraction instrument. The soil nutrient in-situ extraction instrument comprises an ion exchange resin module and a testing instrument for loading the ion exchange resin module, wherein a clamping groove is formed at one end of the testing instrument, and the ion exchange resin module is fastened in the clamping groove through a fixing piece matched with the clamping groove. The soil nutrient in-situ extraction instrument is simple in structure and easy to implement, the ion exchange resin module is fixed in the clamping groove of the testing instrument, the ion exchange resin module is positioned in the position of a through hole of the testing instrument, and the adsorption function of the ion exchange resin module is not affected; and furthermore, a sharp port is formed at one end of the testing instrument, the device can be easily inserted and fixed in any position of a plowing layer under the condition of not stirring soil, and the operation is simple and convenient.
Description
Technical field
The present invention relates to a kind of extraction apparatus, relate in particular to a kind of soil nutrient in-situ extraction appearance.
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 the field situation of soil nutrient again.Because the 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 the effective status of soil nutrient to plant, be that the fertilizer recommendations of foundation does not often meet the actual needs of crop to nutrient very much with conventional soil testing.And, measuring same kind of nutrient in different regions and often need use different method of testings, the gained result is difficult to mutual comparison.
To 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 big superiority.Because ion-exchange-resin process is to come the effective supply of testing soil nutrient to plant through ion exchange, and is similar to nutrient absorbing mechanism with plant, with plant nutrient absorbing 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 the required various Different Nutrients of plant simultaneously.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 has only the 20-30% of conventional method.Yet nowadays this method only is applicable to the experimental determination of soil nutrient, as measuring the nutrient of field original position, also need be equipped with suitable support equipment.
Summary of the invention
The objective of the invention is to provides a kind of soil nutrient in-situ extraction appearance to the problems referred to above, and it has simple in structure, is easy to realize, measures the process convenient reliable characteristics.
The objective of the invention is to realize through following technical scheme:
A kind of soil nutrient in-situ extraction appearance; Comprise the ion exchange resin module and be used to load the tester of this ion exchange resin module; One end of said tester has through hole; The two ends of said through hole are provided with draw-in groove, and said ion exchange resin module is anchored in the draw-in groove through the fixture that is complementary with said draw-in groove.
Further, said ion exchange resin module is a flat structure.
Further, the said tester end that has through hole one end is provided with sharp-crested.
Further, said sharp-crested is a triangular structure.
Further, the outside surface of said tester is provided with fin or the groove that indicates metering scale.
Further, said tester is made of plastics.
Further, said draw-in groove and fixture are the intercalation structure, and said fixture is a L type structure, and it is intercalated in the draw-in groove.
Beneficial effect of the present invention does, said soil nutrient in-situ extraction appearance is simple in structure, be easy to realize that 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 influence the adsorption function of ion exchange resin module, and tester one end is provided with sharp-crested, can be under the situation of not stirring the soil body; Easily this is installed insertion and is fixed in any position of arable layer, simple, convenient.

Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through embodiment.
Please referring to figs. 1 through shown in 3, in present embodiment, a kind of soil nutrient in-situ extraction appearance; Comprise ion exchange resin module 1 and be used to load the tester of this ion exchange resin module 1, said ion exchange resin module 1 is a flat structure, and said tester is made of plastics; The outside surface of tester is provided with the fin 4 that indicates metering scale, and the one of which end has through hole, and said 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; Said sharp-crested 3 is a triangular structure, and said ion exchange resin module 1 is anchored in the draw-in groove through the fixture 2 that is complementary with said draw-in groove, and said draw-in groove and fixture 2 are the intercalation structure; Said fixture 2 is a 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 inserts and is fixed in any position of arable layer down; The fin 4 that plays the sign metering scale that is provided with on the tester outside surface can be known to reflect that soil nutrient in-situ extraction appearance 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 invention and characteristic; The present invention is not limited by the foregoing description; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various variations and change, and these variations and change all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
