| 摘 要： | 为了明确黑土区玉米田合理的深松方式,探索不同深松处理对土壤物理性状和产量的影响,以先玉335为供试材料,进行玉米田深松改土试验。结果表明:深松改土后土壤容重和坚实度显著降低,土壤田间持水量提高;深松可以提高玉米籽粒产量,其中以秋季深松30cm效果最好。

| Abstract: | In order to define the reasonable subsoiling way of black soil region in the maize field and explore the effect of subsoiling on soil physical properties and maize yield.The subsoiling tillage was tested from 2011to2012 in Harbin of Heilongjiang province,while Xianyu 335 was used as material.The results showed that bulk density,hardness and water content of soil increased and maize yield improved,and the effect of subsoiling in autumn（30cm）was the best. |

| Keywords: | maize subsoiling soil bulk density soil water content yield |
