At present, the soil ions content detection technique of China comprises field sampling, room-dry, weighs, chemical method is extracted, the instrumental analysis supervisor, and time and effort consuming, cycle are long.And the result that this classic method records only can represent the reserves of field soil ions content, and owing to the suction-operated of soil particle to nutrient, the result who records can not represent that these are exactly the absorbent effective supply amount of plant.Therefore, the result of this conventional test methodologies mensuration can not truly reflect effective nutrient in soil content.
The various countries scientist absorbs the nutrient rule seeking a kind of crop root of simulating, and exempts the environment ions content extracting method of sample collecting and preparation, makes quick, simple and direct, accurate, the low consumption of soil ions content analysis.
A kind of new soil testing technology is launched in developed country, promptly extracts the soil ions content with ion exchange, its process simulation crop root absorb the principle of nutrient, more can actually express can be by the effective content of plant utilization in the soil.
A patent U.S.Pat.No.4 of the U.S., 816,161 will be packaged into spherical or hemispheric ion exchange resin is embedded in the soil, once just can extract multiple environment ions content by ion-exchange.The shortcoming of this method is that spherical ion exchange resin can not fully contact with interface to be measured, can occur secondary diffusion exchange in exchange, except scientific research is used, and also not a large amount of use the in the production.
Another patent U.S.Pat.No.6 of the U.S. is pressed into diaphragm with ion exchange resin after 242,261 improvement and is fixed on a kind of framework, makes film can directly insert the nutrient that extracts in the soil in the soil.The film that shortcoming is to be fixed on the framework has the space when framework inserts in the soil and between soil, require operating personnel to want carefully that the film framework is the other soil of extreme care to tread, soil is contacted with film close, and simultaneously, the ion exchange capacity of diaphragm is significantly less than microspheric ion exchange resin.
The research report that many scientists make with these two kinds of patented products or similar products proves that the content of nitrogen phosphorus potassium sulphur in the soil that records with ion exchange process is significantly relevant with plant absorbing, but the common drawback of prior art products is that gained poor reproducibility is as a result measured in different operating personnel or different place at present, and the practical application on producing is subjected to certain limitation.
Summary of the invention
