[0030] The first step is to accurately weigh 200g of air-dried soil samples, remove gravel, plant roots and other debris, and add them to a clean centrifuge bottle.
[0031](1.a): Soil sample air-drying process. Place the collected soil samples in a cool, dry, ventilated room without direct sunlight, spread them flat on a clean cool soil rack, plastic cloth or tarpaulin, and lay them in a thin layer for faster air-drying. When the soil sample reaches a semi-dry state, it is necessary to gently crush the large soil clods in the soil by hand to avoid the soil from forming hard lumps after the soil is completely air-dried and not easy to crush. In order to dry faster, the soil sample can be turned over. turn. At the same time, pick out the big grass roots in the soil to avoid crushing the big grass roots during rolling and making it more difficult to pick them out. Air-dried rooms are required to prevent acid, alkali and other gases, aerosols and dust pollution. When the soil ...
