In inversion tillage systems, the mouldboard plough is fundamental for producing a desirable seedbed. The desired ploughing quality is achieved when the plough layer is inverted homogeneously. This is, however, difficult to obtain in the main‐headland intersection zone where the plough is lowered and elevated, as ploughed and unploughed triangles are formed. This results in zones where the soil is inverted twice, which may result in poor residue and weed incorporation and a poor seedbed quality. The design of the three‐point linkage‐attached mouldboard plough has not changed since the 1950s, but the number of furrows has increased, which has increased the size of the aforementioned triangles. A novel ploughing system was introduced to meet these headland challenges, where each plough section can be lowered and elevated independently. The aim of this study was to evaluate the effects of using a section‐controlled mouldboard plough. Two similarly designed, randomized, field plot experiments were conducted on two different soil types (sandy loam and loamy sand) on a stubble field and grass field. The study showed that the section‐controlled plough reduced the main‐headland overlap area by ~98%. The results of a range of soil physical properties measurements and seedbed quality analyses showed that the section‐controlled plough created a homogeneous loosened seedbed quality, improving the incorporation of crop residues and leaving fewer residues on the soil surface. Furthermore, the section‐controlled plough showed additional benefits, for example wedge operations and visual line marking.

新型分段控制的刨花板耕作系统优化了岬角的土壤转化

在反向耕作系统中,模板犁是生产理想苗床的基础。当耕犁层均匀倒置时,可以达到理想的耕犁质量。但是,在犁头下降和升高的主岬角相交区域,由于形成了犁形和非犁形三角形,很难做到这一点。这导致土壤被倒置两次的区域,这可能导致残渣和杂草混入较差,以及苗床质量较差。自1950年代以来,三点连接式模板犁的设计没有改变,但犁沟的数量有所增加,这增加了上述三角形的尺寸。引入了一种新颖的耕作系统来应对这些岬角挑战,在这些耕作中,每个耕作部分都可以独立降低和升高。这项研究的目的是评估使用分段控制的刨花板犁的效果。在秸秆田和草田的两种不同土壤类型(沙壤土和壤土)上进行了两个类似设计的随机田间试验。研究表明,分段控制的犁将主岬角重叠面积减少了约98%。一系列土壤物理性质测量和苗床质量分析的结果表明,截面控制的犁产生了均匀的疏松苗床质量,改善了农作物残渣的吸收并减少了土壤表面的残渣。此外,分段控制的犁还具有其他优势,例如楔形操作和视线标记。在秸秆田和草田的两种不同土壤类型(沙壤土和壤土)上进行了两个类似设计的随机田间试验。研究表明,分段控制的犁将主岬角重叠面积减少了约98%。一系列土壤物理性质测量和苗床质量分析的结果表明,截面控制的犁产生了均匀的疏松苗床质量,改善了农作物残渣的吸收并减少了土壤表面的残渣。此外,分段控制的犁还具有其他优势,例如楔形操作和视线标记。在秸秆田和草田的两种不同土壤类型(沙壤土和壤土)上进行了两个类似设计的随机田间试验。研究表明,分段控制的犁将主岬角重叠面积减少了约98%。一系列土壤物理性质测量和苗床质量分析的结果表明,截面控制的犁产生了均匀的疏松苗床质量,改善了农作物残渣的吸收并减少了土壤表面的残渣。此外,分段控制的犁还具有其他优势,例如楔形操作和视线标记。研究表明,分段控制的犁将主岬角重叠面积减少了约98%。一系列土壤物理性质测量和苗床质量分析的结果表明,截面控制的犁产生了均匀的疏松苗床质量,改善了农作物残渣的吸收并减少了土壤表面的残渣。此外,分段控制的犁还具有其他优势,例如楔形操作和视线标记。研究表明,分段控制的犁将主岬角重叠面积减少了约98%。一系列土壤物理性质测量和苗床质量分析的结果表明,截面控制的犁产生了均匀的疏松苗床质量,改善了农作物残渣的吸收并减少了土壤表面的残渣。此外,分段控制的犁还具有其他优势,例如楔形操作和视线标记。
