【摘要】 本研究通过盆栽试验探讨了苯达松对不同生育期食葵(DK119)和油葵(G101)的敏感性,目测药害水平和株高抑制率的实验结果表明:苯达松对食葵(DK119)非常敏感,三对真叶期以前均不能施用;对油葵(G101)的安全性相对较高,在油葵一对真叶期、二对真叶期的最佳施药量分别为720-1050、720-750g a.i./ha,三对真叶期较敏感,不能施用。更多还原

【Abstract】 The potted experiment was carried out to evaluate the sensitivity of Bentazone to eatable and oiled sunflower in different growth stages.The results indicated that bentazone was very sensible to eatable sunflower(DK119) and comparatively safe to oiled sunflower(GlOl).It couldn’t be applied in eatable sunflower(DK119) during the period of lto 6 true leaves and oiled sunflower(GlOl) of 6 true leaves stage,and the best dosages applied in oiled sunflower(GlOl) of 2 and 4 true leaves were 720-1050 g a.i./ha and 720-750 g a.i./ha respectively.更多还原
