摘要
为了解四环素对玉米生长期产生的影响,通过盆栽试验研究了山西省石灰性粘壤土、石灰性砂壤土施入含四环素鸡粪对玉米生长的影响,结果表明,所测指标中,除玉米的胞间CO2浓度以外,石灰性砂壤土各处理玉米的株高、根长、茎叶重、根重、籽粒重、净光合速率、蒸腾速率、气孔导度、叶绿素等指标均明显低于石灰性粘壤土,两种土壤玉米的株高、根长、茎叶重、根重、籽粒重、净光合速率、蒸腾速率、气孔导度、叶绿素等指标在含四环素鸡粪的处理中明显低于不含四环素鸡粪的处理。四环素对玉米的生长具有明显的抑制作用。
In order to understand the effect of tetracycline on corn growing period,pot experiments were carried on to study the impact of applying chicken manure containing tetracycline to calcareous clay loam and calcareous sandy loam in Shanxi Province on corn growth.The results indicated that ： amongst the measured indicators,all tested parameters,including the plant height,root length,leaf weight,root weight,seed weight,net photosynthetic rate,transpiration rate,stomatal conductance,chlorophyll of corn,were considerably lower in the calcareous sand soil than those in the calcareous clay loam,except intercellular CO 2 concentration.The values of the plant height,root length,leaf weight,root weight,seed weight,net photosynthetic rate,transpiration rate,stomatal conductance,chlorophyll of corn in two soils applied chicken manure containing tetracycline were lower than those without tetracycline.The results indicated that tetracycline had significantly inhibitory effect on the growth of corn.
