| 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,研究了深松少耕技术对土壤物理性状、水分利用率、土壤蓄水能力及玉米产量的影响。结果表明：深松少耕后,土壤容重在土壤耕层10-40 cm的范围内比对照降低22.1个百分点;土壤含水量在土壤耕层10-30 cm范围内高于对照,差异达显著水平,并在15-25 cm达极显著水平;土壤耕层0-50 cm范围内田间持水量均高于对照,差异达到显著或极显著水平;同时,深松少耕后玉米田增产1 602 kg.hm-2,差异达到显著水平。

| Abstract: | According to the mensuration and analysis of soil permit heaviness,soil moisture,soil maximum moisture and the yield,the effects of subsoiling and fewer-tillage on soil physical characters,water use efficiency,soil conservation storage competence and maize yield were studied.After the subsoiling and fewer-tillage,the results indicated：soil permit heaviness descend 22.1 percent point than CK in 10～40 cm soil depth;soil moisture higher than CK in 10～30 cm soil depth,the discrepancy attained notable level in 10～30 cm soil depth,the discrepancy attained maximum notable level in 15～25 cm soil depth;soil maximum moisture higher than CK in 0～50 cm soil depth;the yield higher 1 602 kg·hm-2 than CK,the discrepancy attained notable level. |
