四种典型稻田除草剂对烟草生长的影响
Effects of 4 typical paddy herbicides on growth of tobacco
摘要
Abstract
Effects of 4 kinds of paddy herbicides on teratogenic dosage, phytotoxicity symptoms, and biological activity of tobacco growth were studied by indoor initial screen and field experiments. Results showed that quinclorac affected height, leaf length and especially leaf width of tobacco plant, whose teratogenic dosage was 2×10-3mg/kg. Bensulfuron-methyl and pyrazosulfuron had little effect on leaf length and width, but had significant effect on plant height, whose teratogenic dosages were both 0.5×10-3mg/kg. Cyhalofop-butyl had little effect on plant height, leaf length and width, even when the dosage was 16 times of that used in paddy field. Due to the inhibition of quinclorac, bensulfuron-methyl and pyrazosulfuron on tobacco root system, which caused the changes of physiological indices such as roots activity and cation exchange capacity, the greater the spraying concentration, the greater the inhibition effects to tobacco. Therefore, field application of quinclorac and sulfonylurea herbicides should be avoided prior to tobacco cultivation.关键词
