透气性和容重都是耕作土壤的重要物理性质,影响着土壤的其他性质和作物的生长发育,所以测定土壤的透气性和容重是有重要意义的。土壤透气性容重测定器能够同 Breathability and bulk density are important physical properties of tillage soil, affecting other soil properties and crop growth and development, so the determination of soil permeability and bulk density is of great significance. Soil permeability tester can be the same
