摘要
亚麻田中18.75ga.i./hm2砜嘧磺隆水分散粒剂的除草试验表明:药后50d,杂草鲜重防效达54%￣99%,与对照相比达极显著差异。在本试验条件下,药后50d内,该药会稍稍抑制亚麻生长,表现出处理的苗矮于对照。但后期这个抑制会逐渐减轻或消除,亚麻生长正常,收割时植株高度与对照没有显著差异。因此,砜嘧磺隆对亚麻安全,除草效果也好,可用于亚麻田除草。
Results from a weed control experiment in flax with rimsulfuron 25% water dispersible granule at 18.75 g a.i/ha showed weed fresh weight reductions ranging from 54 to 99% 50 d after treatment. Differences between treated and untreated plots were highly significant. Under the given experimental conditions, rimsulfuron slightly inhibited flax growth,resulting in shorter plants 50 d after treatment. At later stages, the inhibition was gradually reduced or completely alleviated. Thus, rimsulfuron is safe for use in flax and provides good weed control as well.
