摘要
马铃薯杀秧措施已经广泛应用于脱毒马铃薯种薯生产中,但实际调查中杀秧效果和杀秧成本,有很大的差异,针对这一问题,本试验选出常用的杀秧机和硫酸铜、百草枯两种化学制剂进行杀秧处理,并对马铃薯的杀秧效果进行了综合比较。结果表明,自制2垄马铃薯杀秧机效果最好,其杀秧成本低,利于机械收获,安全性高,是可以大力推广的技术措施。
Potato haulm killing had been applied in virus-free seed potato production, and there were some differences in cost and effect of the practice. Haulm killing by haulm cutter, cooper sulfate and paraquat were compared in field experiments. The best results were obtained from haulm cutter, which was low cost, good for operating harvester, and no chemical pollution. Therefore, using haulm cutter in seed potato production should be recommended.
