Pretreatment device and method for available phosphorus in soil

The invention provides a pretreatment device and method for available phosphorus in soil, and belongs to the technical field of soil detection treatment, the pretreatment device comprises a box, a plurality of bearing parts arranged in a square are arranged in the box, each group of bearing parts is composed of a plurality of same bearing parts, and the bearing parts are arranged in the box. After a glass bottle filled with soil and solution is arranged in the bearing parts, the bearing parts in the box can rotate back and forth around the central axes of the bearing parts when shaking back and forth together. The problems that the glass bottles need to be oscillated when soil is contained in the glass bottles to be fully blended with a solution to ensure the accuracy of detection data, the labor intensity of manual operation is high, and oscillation blending cannot be carried out on multiple groups of glass bottles are solved. 本发明提供一种土壤中有效磷前置处理装置及方法，属于土壤检测处理技术领域域，包括箱子，所述箱子的里面安设着正方形排列的若干承托部，各组所述承托部都经由若干一样的承载部
