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测定和分析,研究了深松免耕技术对黑龙江省第二积温带土壤物理性状及玉米产量的影响。结果表明:深松免耕保护性耕作后,土壤耕层10～40cm土壤容重比对照(传统中耕)下降11.8个百分点;深松的土壤耕层0～40cm含水量比对照高出10.4个百分点;土壤耕层15～25cm田间持水量比对照高出21.7个百分点。玉米产量比对照增产1556kg/hm2。According to the mensuration and analysis of soil permit heaviness, soil moisture, soil maximum moisture, corn yield, the article researched the effects of subsoiling and no-tillage on soil physical characters and corn yield in second temperate zone of Heilongjiang province. After the subsoiling and no-tillage, the results showed soil permit heaviness was descender 11.8% than CK in 10 - 40 cm soil depth; soil moisture was higher 10.4% than CK in 0 - 40 cm soil depth; soil maximum moisture was higher 21.7% than CK in 15 - 25 cm soil depth. The corn yield was higher 1 556 kg/ha than CK.
