| 摘 要： | 通过对土壤容重、土壤含水量、土壤田间持水量及产量的分析对比,研究深松40 cm对土壤耕层的物理性质及对玉米产量的影响。结果表明,在0~10 cm深松与对照土壤容重差异不显著,土壤含水量和田间持水量差异达到极显著水平;而在10~40 cm深松与对照的土壤容重、含水量、田间持水量均达到极显著差异水平,玉米产量比对照增产8.0%。

| Abstract: | According to the mensuration and analysis of soil bulk density, soil moisture, soil field capacity and corn yield, the article researched the effects of subsoiling 40 cm on soil physical characters and corn yield. The results showed there was no significant difference between the subsoiling treatment （0-10 cm） and CK in soil bulk density, and there were significant difference in the soil moisture and soil field capacity. The difference of soil bulk density, soil moisture and soil field capacity reached significant level than CK in 10-40 cm soil depth. The corn yield was higher 8.0% than CK. |
