【摘要】 利用青油14号油菜为生物测定指示植物,在青藏高原栗钙土中测得10%甲磺隆WP对油菜的药害敏感点在土壤含量为0.0586×10-3～0.1172×10-3mg/kg之间,甲磺隆土壤残留半衰期在24.57～27.70d之间,甲磺隆在土壤中存在积累作用。更多还原

【Abstract】 Using Qingyou No.14 rape as the indicating plant, the change of metsulfuron in chestnut soil of Qingzang highland was determined. The result shows that the sensitive point of metsulfuron to rape was 0.058 6×10-3 to 0.117 2×10-3 mg/kg. The half-life of metsulfuron residual was 24.57 to 27.70 days.
