Abstract:In this paper,different concentrations of oxytetracycline (control,soil + manure (oxytetracycline),soil + manure (oxytetracycline) 6.4g/kg soil + manure (oxytetracycline) 12.8g / kg soil + manure (oxytetracycline) 25.6g/kg) on maize plant height,root length,plant fresh weight,root fresh weight,plant dry weight,root dry weight,seed weight,chlorophyll,photosynthetic rate,transpiration rate were determined.The results showed that:It can be seen to join oxytetracycline corn plant height,root length,plant fresh weight,root fresh weight,plant dry weight,root dry weight,seed weight,eight indicators of the chlorophyll at low concentrations inhibition.However,with increasing concentrations,but promote the role is no longer enhanced showing a calm and curve,and finally reached a high; low concentrations of oxytetracycline on the photosynthetic rate and transpiration rate,but with the increasing concentration of the soil mold factor on photosynthesis rate and transpiration rate has a significant inhibitory effect in high concentration Shiyou a catalytic role; oxytetracycline in 25.6g/kg plant fresh weight and strains of dry weight sensitivity strong,still have role; oxytetracycline on plant height and root length and chlorophyll concentration of 6.4g/kg significantly inhibited even less than the control group;,by analysis of variance,the 10 indicators of corn measured reach very significant levels of plant fresh weight,root fresh weight,plant dry weight,root dry weight,seed weight of these five indicators; reach a significant level,there is plant height,root length,chlorophyll,photosynthetic
