几种解毒剂对烟草二氯喹啉酸药害的修复效果
Remediation Effects of Several Antidotes on Phytotoxicity of Quinclorac to Tobacco
摘要
Abstract
After the excessive application of herbicide Quinclorac in paddy field, the residue of Quinclorac in the soil can cause the growth malformation of the later crop tobacco.In order to reduce the influence of Quinclorac on the growth of tobacco plants, the author carried out pot experiments to study the remediation effects of different dosages (375, 750, 1125 and 1500 kg/hm2 ) of quick lime on the phytotoxicity of Quinclorac to tobacco, and screened out the appropriate dosage of quick lime with optimal remediation effect.Based on this, the remediation effects of appropriate dosage of quick lime and other antidotes (amino acid water-soluble fer-tilizer, humic acid water-soluble fertilizer, microbial fertilizer and trace element soluble fertilizer ) were compared through field tests.The results of pot experiments showed that the application of 1125 kg/hm2 quick lime had very good remediation effect on the phytotoxicity of Quinclorac residue to tobacco.The results of field tests indicated that applying microbial fertilizer had a certain re-mediation effect, but could not make tobacco plants return to normal.In comparison with the application of other antidotes, the ap-plication of 1125 kg/hm2 quick lime had the best effects on the leaf width, leaf length and plant height of tobacco plants, and ob-tained the highest yield and output value of tobacco leaf.Therefore, when Quinclorac was excessively applied in paddy field, 1125 kg/hm2 quick lime with water should be applied before planting tobacco.关键词
