Full-automatic integrated soil nutrient extraction system

The invention relates to a full-automatic integrated soil nutrient extraction system, and effectively solves the problems that the process of preparing a soil nutrient solution to be detected during soil nutrient detection in the prior art is relatively tedious and relatively long in consumed time. According to the technical scheme, the soil nutrient extraction system is in a sealed state when mixed liquid is prepared, the risk of liquid spilling is avoided, the filtering efficiency of the mixed liquid is improved by controlling expansion of an annular air bag through a sealed space environment during liquid filtering, the detection speed of soil nutrients is increased, and the detection accuracy of the soil nutrients is improved. And a large amount of time can be saved when batch soil sample detection is carried out. 本发明涉及全自动一体化土壤养分提取系统，本发明有效解决了现有在对土壤养分检测时配制土壤养分待测液过程较为繁琐且耗时较长的问题；解决的技术方案包括：该土壤养分提取系统在配制混合液时均处于密封状态下，不会出现液体洒出的风险，在进行液体过滤时借助密封的空间环境通过控制环形气囊的膨胀从而实现加快对混合液的过滤效率，提高了土壤养分的检测速度，在进行批量土壤样品检测时可节省大量的时间。
