不同原油浓度对两种农作物的生长特性影响评价

Effect of different petroleum densities on growth characters of two kinds of crops

通过测定农作物的生长状况及产品品质,研究了不同原油含量对农作物生长状况的影响.试验结果表明,随着土壤中原油含量的增加,玉米、大豆中总烃、芳烃、总酚含量也相应增多,呈明显的正相关性.当加入0.5 g/kg的石油时,玉米果实中的总烃、芳烃、总酚含量分别为37.25 m g/kg、9.80 m g/kg、1.394 m g/kg,大豆中分别为52.14 m g/kg、12.77 m g/kg、1.693 m g/kg.当石油含量为0.5～1.0 g/kg时,对农作物的生长发育有促进作用,同时促进淀粉、蛋白质的合成,增加果实质量;当含量为3.0 g/kg时,促进效果下降.
