| 中文摘要: |
| 为探讨水基废弃钻井泥浆作为粗质地土壤改良剂的可能性，研究施加不同量水基废弃钻井泥浆对土壤基本物理性质和作物生长的影响，利用室内甜菜盆栽试验，分别在沙黄土和黄绵土中添加2%、4%、8%、12%（干基）含量的水基废弃钻井泥浆，为缓解添加水基废弃钻井泥浆可能引发的土壤pH值过高问题，补充添加石膏处理，试验分为对照组、泥浆组和泥浆+石膏组。结果表明，不添加石膏情况下，两种土壤施加不同含量的废弃泥浆均没有导致土壤盐碱化，且黏粒相对含量增加，蒸散量减少。添加石膏后pH降低，盐分含量显著升高，阻碍了作物生长。从作物生长来看，两种土壤施加8%含量废弃泥浆对甜菜生长促进效果最佳，种植40 d后，沙黄土甜菜株高比对应的对照处理增加了41.59%，叶面积增加了2.43倍，生物量增加了3.54倍，叶片SPAD值增加了58.18%；黄绵土甜菜株高比对应的对照处理增加了1.75%，叶面积增加了32.03%，生物量增加了14.59%，叶片SPAD值增加了27.65%。研究表明，一定含量的废弃泥浆对于粗质地土壤改良和作物生长有促进作用，研究结果对油气田水基钻井废弃物就地利用和开采区粗质地土壤改良具有一定的借鉴意义。 |

| The effects of water-based waste drilling mud on soil physical properties and crop growth were studied. An indoor pot experiment was used to add 2%, 4%, 8%, and 12%(dry matter basis) water-based waste drilling mud into both sandy and loam loess. To alleviate the increase in soil pH caused by the addition of water-based drilling waste mud, the pot experiments were supplemented with a gypsum treatment. The experiment was divided into a control group, the mud group, and the mud+gypsum group. A crop of sugar beet was planted. Results showed that the application of different amounts of waste mud to the two types of soil did not lead to salinization in the absence of gypsum, and that the clay content increased while plant evapotranspiration decreased. Adding gypsum decreased soil pH but increased soil salt content significantly and prevented crop growth. In terms of the latter, pots containing soil with the 8% waste mud content saw the best sugar beet growth in both types of soils. After 40 days, the height of the sugar beet plants increased by 41.59%, their leaf area increased 2.43 times, their biomass increased 3.54 times, and their leaf SPAD value increased by 58.18% in sandy loess. In loam loess, the plant height, leaf area, biomass, and SPAD of the leaves increased by 1.75%, 32.03%, 14.59%, and 27.65% respectively. A certain amount of waste mud has a positive effect on the soil physical properties, and thus the growth of crops. The results indicate that water-based drilling waste from the oil and gas industry could be used on-site to improve coarse soils and decrease the cost of waste drilling mud. |
