Abstract

Soil compaction primarily stems from compression and shear stresses due to field wheeling processes. Laboratory studies have revealed the effects of these two types of stresses on soil structure and pore functions, but their consequences for soil properties and crop under field conditions need to be quantified. In this study, the temporal changes of soil physical conditions and maize growth under repeated wheeling were studied on a Mollisol. At field capacity, wheeling plots were created by a 10.4 Mg harvester with 1, 3, 5, and 21 wheeling passes (C1, C3, C5, and C21). Soil volume water content (θ_v) and matric potential (Ψ) were monitored during a maize growing season. The results showed that field soil deformed progressively with the increase of wheeling frequency: After 1, 3, 5, and 21 wheeling passes, the rut depths were 6.4 cm, 8.0 cm, 9.5 cm, and 13.7 cm, respectively. In response to soil compaction, the wheeling plots exhibited significant changes in soil water status with increased θ_v, less negative Ψ, greater water retention, but decreased water availability for plants, which lasted for the whole growing season. The C5 and C21 treatments frequently experienced waterlogging during the wet season and more severe cracking during the dry season. Compared to the control, the above-ground biomass of maize in the C1, C3, C5, and C21 treatments decreased by 14.5 %, 36.9 %, 37.0 %, and 56.4 %, respectively, and crop yield reduced by 9.7 %, 30.7 %, 38.4 %, and 59.7 %, respectively. At a load of 10.4 Mg, a threshold wheeling pass of two was recommended in the study area.

反复轮作对Mollisol土壤物理条件和玉米生长的量化影响

土壤压实主要源于现场轮转过程产生的压缩和剪切应力。实验室研究已经揭示了这两种类型的应力对土壤结构和孔隙功能的影响，但它们在田间条件下对土壤性质和作物的影响需要量化。研究了反复轮作条件下土壤物理条件和玉米生长的时间变化规律。在田间容量下，一台10.4 Mg的收割机用1、3、5和21个轮转通道（C1、C3、C5和C21）创建轮转地块。在玉米生长季节监测土壤体积含水量（θv）和基质电位（Ψ）。结果表明：随着轮转次数的增加，现场土壤变形逐渐加剧，轮转1次、3次、5次和21次后，车辙深度分别为6.4 cm、8.0 cm、9.5 cm和13.7 cm；在土壤压实的影响下，轮作样地土壤水分状况发生了显著变化，θv增大，负Ψ减小，保水能力增强，但植物水分有效性降低，这种变化持续整个生长季。C5和C21处理在雨季涝渍频繁，旱季开裂更为严重。与对照相比，C1、C3、C5和C21处理的玉米地上部生物量分别减少14.5 %、36.9 %、37.0 %和56.4 %，产量分别减少9.7 %、30.7 %、38.4 %和59.7 %。当负荷为10.4 Mg时，建议研究区域的阈值为2。

期刊介绍： Soil & Tillage Research examines the physical, chemical and biological changes in the soil caused by tillage and field traffic. Manuscripts will be considered on aspects of soil science, physics, technology, mechanization and applied engineering for a sustainable balance among productivity, environmental quality and profitability. The following are examples of suitable topics within the scope of the journal of Soil and Tillage Research: The agricultural and biosystems engineering associated with tillage (including no-tillage, reduced-tillage and direct drilling), irrigation and drainage, crops and crop rotations, fertilization, rehabilitation of mine spoils and processes used to modify soils. Soil change effects on establishment and yield of crops, growth of plants and roots, structure and erosion of soil, cycling of carbon and nutrients, greenhouse gas emissions, leaching, runoff and other processes that affect environmental quality. Characterization or modeling of tillage and field traffic responses, soil, climate, or topographic effects, soil deformation processes, tillage tools, traction devices, energy requirements, economics, surface and subsurface water quality effects, tillage effects on weed, pest and disease control, and their interactions.
