为了弄清石油污染土壤中石油类对农作物的影响，吉林油田进行了一年的田间玉米种植试验。在不同浓度水平，分别对玉米出苗率、可见外观特性、百粒重、产量和品质进行了较系统的观察、监测、类比分析。结果表明，土壤中石油含量的不同，对玉米生长过程各项指标有不同的影响。并找出吉林油田土壤—玉米系统中影响玉米生长及其产量的土壤临界含油量。

In order to understand the influence on crop caused by petroleum content of polluted soil by petroleum, the trial corn planting in the soil contaminated by petroleum has been conducted in Jillian oil field for one year. The germination rate, the visible appearance, the weight of hundred particles, the production rate and the quality of corn, were observed and compared under the condition of various oil concentration of soil. The result shows that the variation of oil concentration of soil has different affection on each index of corn growth, and the critical oil concentration of soil influencing corn growth and its production in the soil-corn system of jilin oil field was determined.
