1999～2002年进行了大豆田除草剂金普施特土壤残留对后茬作物影响的小区试验。试验结果表明,金普施特50g/hm2(有效成份,下同)推荐剂量和倍量100g/hm2处理,施药后12个月可种植小麦和玉米。50g/hm2推荐剂量下24个月后种植白瓜籽、油菜、马铃薯、亚麻、白菜无明显药害,倍量亚麻、白菜苗期有轻度抑制,对甜菜药害严重。36个月后,50g/hm2处理对甜菜无明显药害,加倍剂量对亚麻、白菜也无明显药害,对甜菜苗期生长仍有较明显抑制,但对产量影响不显著。
From 1999 to 2002, a field trial was conducted on the effects of the soil herbicide Jinpuchu residue on the succession crop. The results showed that the recommended dosage of Jinpuchu 50g / hm2 (active ingredient, the same below) was treated with 100g / hm2, and wheat and corn could be planted 12 months after application. No significant phytotoxicity of white seeds, rape, potato, flax and cabbage was observed after 24 months at the recommended dose of 50g / hm2. After 36 months, 50g / hm2 treatment showed no significant phytotoxicity on beet, no doubling phytotoxicity on flax and cabbage was observed, but there was still obvious inhibition on the growth of sugar beet seedling, but the effect was not significant.
