摘要
为了探寻黑龙江省早熟地区玉米最适深松时期及深度,探讨不同深松方式对土壤物理性状和作物产量的影响。2009～2010年在黑龙江省克山县进行了玉米不同深松时间及深度耕作试验。结果表明：深松处理的土壤物理性状得到明显改善,深松处理产量好于常规耕作,秋季深松＆gt;春季、夏季深松＆gt;常规耕作,秋季深松40cm处理产量水平最高。
In order to explore the most suitable subsoiling period and depth in the early maturing areas of Heilongjiang province and to investigate the effect of subsoiling on soil physical properties and crop yield.The subsoiling tillage of maize were tested from 2009to 2010in Keshan county of Heilongjiang province.The results showed that soil physical properties of subsoiling could be improved significantly,yield of subsoiling was better than conventional tillage,subsoiling in autumnsubsoiling in spring and summerconventional tillage,yield of subsoiling in autumn（40cm）was the highest.
