通过可调翼深松铲的正交试验与深松后效试验，研究了深松的影响范围、土壤体积密度的变化规律和深松周期的确定方法，结果表明，悬挂位置、翼板位置、入土角对松土深度有显著影响，深松影响的宽度范围为深度的２．２倍。提出了保持麦地松后地表硬度一致的方法。后效表明，１次深松至少可以持续２年。还分析了深松机组的入土性能。
Through the orthogonal experiment and the after-deep-well test, the influence range of subsoiling, the law of soil bulk density and the determining method of subsoiling period were studied. The results showed that the location of suspension, the position of wing, The depth of loosening had a significant effect on the depth of loosening, and the width of deep loosening affected the depth to 2.2 times. Proposed to keep the surface hardness of the soil after the same method. After-effects show that a deep pine can last at least 2 years. The soil subsidence performance of subsoiling unit was also analyzed.
