室内盆栽和田间小区模拟普施特土壤残留试验 ,探索了活性炭、萘二甲酐 (NA)和液体有机处理复合剂 (penatron)对普施特的解毒效果。结果表明 ,液体有机处理复合剂与普施特同时施入土壤 ,间隔 30天后种植甜菜和油菜 ,可以明显地降低普施特对甜菜和油菜幼苗鲜重的抑制率 ,有较显著的解毒效果。活性炭拌种也能降低普施特对甜菜和油菜幼苗鲜重的抑制率 ,但效果不及 penatron明显。NA拌种或拌肥料做种肥用 ,对玉米、高粱、油菜和甜菜出苗没有影响 ,对玉米、油菜和甜菜有一定的解毒效果 ,而对高粱没有明显的解毒作用
Pot experiments were conducted in indoor potted and field plots to study the effects of activated carbon, naphthalene dianhydride (NA) and penatron on the detoxification of Pstat. The results showed that the combination of liquid organic compounding agent and psost was applied to the soil at the same time, and the sugarbeet and rapeseed were planted 30 days apart, which could significantly reduce the inhibitory rate of pinaster on the fresh weight of sugarbeet and rape seedlings. Activated charcoal seed dressing also reduced the inhibitory rate of perch on the fresh weight of beet and rape seedlings, but the effect was not as obvious as that of penatron. NA dressing or mixed fertilizer as a fertilizer, corn, sorghum, rape and sugar beet emergence has no effect on corn, rape and sugar beet detoxification effect, but no obvious detoxification of sorghum
