Description
Technical field
The present invention relates to a kind of soil nutrient speed survey ionic membrane inserted sheet and method of testing thereof, belong to soil nutrient technical field of measurement and test.
Background technology
Carry out for crop production systems the history that corresponding fertilizer practice research and apply had more than 100 year in the world, developed into the fertilising of application Formula fertilization by soil testing quantitative guidance from early stage empiric fertilization.Wherein soil nutrients variability is the basis of fertilization recommendation, and the mensuration of current soil nutrient adopts laboratory conventional determining method usually, and its process mainly comprises two aspects, and one is the extraction of soil nutrient, and another is the determination and analysis of nutrient after extracting.Although conventional determining method result is comparatively accurate, but need the analytical instrument (flame photometer, spectrophotometer etc.) of comparatively specialty, minute is long, and (soil sample different in kind, mensuration project are different, from air-dry to measuring the time terminating to need 3-5 days), mensuration expense is relatively high, and need professional to carry out the operation in operation and maintenance laboratory, thus constrain the popularization of fertilization compositions based on earth measurement work.
All the time, people make every effort to the soil nutrients variability method sought more accurately, easily and fast.For the lixiviate of nutrient in soil, existing large quantifier elimination, be mostly about digestion agent selection and improve.From eighties of last century fifties, ion exchange resin starts the validity being applied to plant nutrient in assessment soil, in recent years, spent ion exchange resin measures the release of nutrient in soil and increases gradually the research of the effective supply of plant, and existing more application ionomer resin film measures the report of the available nutrient of soil.Its principle is the ion exchanging function of application ionomer resin film, by ion-exchange reactions by surperficial in it for the nutrient ionic adsorption of the soil liquid and soil surface, then determines the nutrient height of soil by analyzing the amount of nutrients that ionomer resin film exchanges.Wherein extract in process of soil nutrient and have following problem to need to solve: 1 resin ion film can be embedded into certain depth position when not spoiled soil structure, need complete taking out after 2 resin ion films exchange soil nutrient in soil, 3 resin ion films are easy to lab analysis operation.So be generally be made into ionic membrane inserted sheet in application the method, amberplex is cut into suitable rectangular blocks, be clipped in preprepared frame of plastic, make root system simulator, after pretreatment, be embedded in soil, after a period of time, take out resin molding, get off with the ion desorb of stripping liquid by resin adsorption again, measure the content of stripping liquid intermediate ion.It is extremely important how ionic membrane inserted sheet makes, if it is too large to make material thickness, affect the contact of ion exchange resin membrane with soil, if material thickness is too thin, do not reach the intensity inserted required for soil, ion exchange resin membrane is fixed on plastics inserted sheet then because overall volume is unfavorable for too greatly laboratory inner analysis operation in addition.
As the Chinese patent literature CN202676524U (patent No.: 201220301740) disclose a kind of soil nutrient in-situ extraction instrument, comprise ion exchange resin module and the tester for loading this ion exchange resin module, one end of described tester has draw-in groove, and described ion exchange resin module is anchored in draw-in groove by the fixture matched with described draw-in groove.Although this tester ion exchange resin membrane can be dismantled, conveniently pre-treatment and parsing are carried out to ionic membrane.But still exist following not enough: 1, ion exchange resin membrane module is installed on inserted sheet by draw-in groove, because the thickness having notch necessarily to increase inserted sheet could realize, affects ion exchange resin membrane and contact with the soil liquid, and then have influence on test effect.2, ion exchange resin membrane module is fastened on draw-in groove by fixture, needs handling all comparatively loaded down with trivial details during actual use.4, owing to using fixture that the out-of-flatness of inserted sheet plane may be caused to strengthen lower difficulty of inserting in soil, also can affect ion exchange resin membrane simultaneously and contact with the soil liquid.5, because of front end have perforate to use plastic material to be more difficult to realize to bear inserted sheet under insert time intensity.
