| 摘 要： | 通过总结多年来盘县农作物病、虫、草、鼠害的调查，预测预报以及防控经验，得出杂草对盘县农作物的危害程度不亚于病虫害的危害程度。其中，旱地杂草的危害尤为严重，每年旱地杂草的危害导致粮食产量损失10%～30%，给盘县农业生产带来较大的损失。为了更好地防除杂草，针对几种除草剂对旱地杂草的抑制效果进行试验，筛选出药效高、低毒、低残留的适合盘县旱地杂草防除的除草剂，结果表明，50%旱草净防除效果最好，其次是41%草甘膦。

| Abstract: | Through summarizing investigation，prediction，prevention and control experience of crop disease，insect，grass and rat of Pan county，it was found that weed hazard degree for crop was not less than diseases and insect pests.Weed in dry land was especially serious harm.Grain yield loss was 10%~30%，which was caused by harm of weed in dry land.It caused great loss to agricultural production in Pan county.In order to achieve better weed control effect，inhibitory effect of herbicides on weed in dry land was tested.High efficacy，low toxicity and low residue herbicide to control dry land weed for Pan county was selected.Results showed that，effect of 50% dry grass net was the best，followed by 41% glyphosate. |
