在田间试验中研究了拖拉机的镇压作用对灰色森林土结构的影响。土壤的许多物理性质是土壤结构派生的,土壤结构是肥力条件主要指标之一,因此在农业生产过程中研究它的变化是很有益的。 In field trials, the effect of tractor crushing on the gray forest soil structure was studied. Many of the soil’s physical properties are derived from the soil structure. Soil structure is one of the main indicators of soil fertility. Therefore, it is beneficial to study its changes in agricultural production.
