摘要
检疫杂草假高粱可随进口粮食从国外传入我国 ,并造成入侵。对 2 0 0 0～ 2 0 0 2年张家港假高粱的检疫资料进行了分析 ,结果表明 :进口粮食中夹带假高粱非常普遍 ,假高粱的检出率虽在不同的进口地区间有一定的差异 ,但是同一地区在年度间、季节间以及批次间的变化不显著。提出了目前应采取的防除措施 ,分别为人工防除、化学防除、生物防除 ;并提出对进口的夹带假高粱的粮食要实行登记监测。最后提出了提高假高粱检出率应注意的有关事项。
Sorghum halepense(L.) Pers.,a quarantine weed,was introduced into China with the import of soybean, which had resulted in its invasion of some regions. The analysis of the quarantine data in Zhangjiagang City during 2000 to 2002 showed that Johnson grass seeds were often found in imported soybean. Although it was not same in the imported soybean from the different regions, the port's checking out ratio for Johnson grass had no significant difference in different seasons and different batches through three years. It was imperative to adopt a persistent quarantine of Johnson grass in the imported farm produces through an integrated consideration of this weed occurrence. In addition, some managements to be adopted was discussed. The imported farm produces with Johnson grass seeds should be treated under control conditions. Some other measures on how to control the weed invasion were proposed further.
