The amount of disturbed soil at various depths resulting from subsoilers with different parameters has an important effect on soil properties (e.g. bulk density and moisture content) and crop performance (e.g. crop root and yield). In this study, effects of wing mounting height (h) (from 75 to 155 mm) of the subsoiler under two straw treatments on soil disturbance areas of both hardpan and top layer, soil properties and winter wheat performance were investigated using field experiments. The results showed that reducing h gave a larger soil disturbance area ratio. Based on the ANOVA outputs, soil moisture content, soil bulk density, grain yield in stubble cover (WOS) region and straw yield in both stubble and straw cover region (WS) and WOS region were significantly affected by h at p < 0.05. Reducing h in subsoiling process gave a larger number of winter wheat roots, reduced soil bulk density and increased soil moisture content and grain yield in WOS region, and improved straw yield in both WS and WOS regions. Mean soil moisture contents of the top 40 cm soil (D40) and the top 100 cm (D100) from surface in WS were higher than those of WOS in different stages, except for these with higher soil moisture content with h of 75 mm. Addition of maize straw cover increased straw yield of winter wheat by 8.23% to 25.27% while it had various effects on wheat grain yield under different treatments (h). This study provided critical information for the design of winged subsoilers under two straw treatments in terms of field soil properties and crop performance.

不同参数的深松机在不同深度产生的扰动土壤量对土壤特性（例如容重和水分含量）和作物性能（例如作物根部和产量）有重要影响。在本研究中，通过田间试验研究了两种秸秆处理下深松机翼安装高度（h）（75 至 155 毫米）对硬土和表层土壤扰动区、土壤性质和冬小麦性能的影响。结果表明，减小 h 产生较大的土壤扰动面积比。基于方差分析结果，土壤水分含量、土壤容重、留茬覆盖 (WOS) 区域的谷物产量以及留茬和秸秆覆盖区域 (WS) 和 WOS 区域的秸秆产量均受 h 显着影响，p < 0.05。减少深松过程中的 h 可以使 WOS 区域的冬小麦根部数量增多，降低土壤容重，提高土壤水分含量和粮食产量，提高 WS 和 WOS 区域的秸秆产量。WS 表层40 cm 土壤(D40) 和表层100 cm (D100) 平均土壤含水量在不同阶段均高于WOS，但土壤含水量较高，h 为75 mm。添加玉米秸秆覆盖使冬小麦秸秆产量提高8.23%～25.27%，但不同处理(h)对小麦籽粒产量有不同影响。该研究为两种秸秆处理下的翼式深松机设计提供了在田间土壤特性和作物性能方面的关键信息。降低了 WOS 地区的土壤容重，增加了土壤含水量和粮食产量，提高了 WS 和 WOS 地区的秸秆产量。WS 表层40 cm 土壤(D40) 和表层100 cm (D100) 平均土壤含水量在不同阶段均高于WOS，但土壤含水量较高，h 为75 mm。添加玉米秸秆覆盖使冬小麦秸秆产量提高8.23%～25.27%，但不同处理(h)对小麦籽粒产量有不同影响。该研究为两种秸秆处理下的翼式深松机设计提供了在田间土壤特性和作物性能方面的关键信息。降低了 WOS 地区的土壤容重，增加了土壤含水量和粮食产量，提高了 WS 和 WOS 地区的秸秆产量。WS 表层40 cm 土壤(D40) 和表层100 cm (D100) 平均土壤含水量在不同阶段均高于WOS，但土壤含水量较高，h 为75 mm。添加玉米秸秆覆盖使冬小麦秸秆产量提高8.23%～25.27%，但不同处理(h)对小麦籽粒产量有不同影响。该研究为两种秸秆处理下的翼式深松机设计提供了在田间土壤特性和作物性能方面的关键信息。WS 表层40 cm 土壤(D40) 和表层100 cm (D100) 平均土壤含水量在不同阶段均高于WOS，但土壤含水量较高，h 为75 mm。添加玉米秸秆覆盖使冬小麦秸秆产量提高8.23%～25.27%，但不同处理(h)对小麦籽粒产量有不同影响。该研究为两种秸秆处理下的翼式深松机设计提供了在田间土壤特性和作物性能方面的关键信息。WS 表层40 cm 土壤(D40) 和表层100 cm (D100) 平均土壤含水量在不同阶段均高于WOS，但土壤含水量较高，h 为75 mm。添加玉米秸秆覆盖使冬小麦秸秆产量提高8.23%～25.27%，但不同处理(h)对小麦籽粒产量有不同影响。该研究为两种秸秆处理下的翼式深松机设计提供了在田间土壤特性和作物性能方面的关键信息。
