东北黑土不同耕作方式和轮作方式下土壤渗透阻力和土壤含水量的空间变异性研究资料有限。通过在吉林省德惠县连续11年的耕作试验，研究了不同耕作方式（免耕、铧式犁和垄作）和轮作方式（玉米-大豆轮作和玉米连作）对土壤含水量和土壤SPR的影响。NT、MP和RT对SPR和水分含量在行、肩和行间的空间分布的影响不同。与MP相比，NT和RT处理分别增加了2.5-17.5 cm和2.5-15 cm的行和行间位置的SPR（p < 0.05）。在0-15 cm土层，NT和RT处理的土壤含水量均显著低于MP处理（p < 0.05）。在MP中发现SPR和含水量的变异性比NT和RT图更大。轮作对土壤含水量和土壤SPR无显著影响（p > 0.05）。耕作方式、取样位置、沿着深对土壤含水量和土壤SPR影响显著（p < 0.05）。
Limited information is available for understanding the spatial variation of soil penetration resistance (SPR) and water content induced by different tillage methods and crop rotations in a black soil of Northeast China. A 11-year tillage experiment in Dehui County, Jilin Province, Northeast China was conducted to evaluate the effects of tillage treatments [no tillage (NT), moldboard plow (MP), and ridge tillage (RT)] and crop rotations (corn-soybean rotation and continuous corn) on SPR and water content in relation to horizontal and vertical variations. Effect of NT, MP, and RT differed on the spatial distributions of SPR and water content among the rows, shoulders, and inter-rows. Compared with MP, NT, and RT treatments increased SPR in row and inter-row positions at the depth of 2.5–17.5 and 2.5–15 cm, respectively (p < 0.05). NT and RT led to significant decrement of soil water content than MP treatment in the rows and inter-rows of 0–15 cm layer (p < 0.05). Greater variability of SPR and water content was found in MP than NT and RT plots. Crop rotation did not have a marked impact on SPR and water content (p > 0.05). Tillage, sampling position, along with depth greatly affected SPR and water content (p < 0.05).
