     摘要：目的研究如何减轻半夏Pinellia ternata(Thunb.) Breit种植中所遇到的杂草危害，为大规模田间种植的高产稳产提供保证，以降低投入，实现利润最大化。方法利用完全随机实验设计研究不同种除草剂的除草效果、产生的药害，提出合理除草优化组合。结果乙草胺在禾本科杂草除草效果上有显著优势，药害较低；乐邦综合除草有效率接近90%，效果好时间长；克无踪除草迅速但产生药害也很大。结论前1年生地除草使用克无踪，第2年春播后喷施乙草胺，杂草多发地点施用1次施田补，第1次倒苗后喷洒乐邦。熟地春季使用1次乙草胺，夏季使用1次乐邦即可。

    Abstract：Objective To study on the way to decrease the harm of weeds during the period of planting Pinellia ternate and to improve output and reduce capital on stream.MethodsDifferent herbicide and their effect were studied using randomized complete experimental design,and the best combination was obtained.ResultsYicaoan had a distinct effect on gramineous weeds and sideeffect was lower;Lebang herbicide had a effectual rate of 90% synthetically and lasted long. ConclusionKewuzong can be used in wild land,Yicaoan is used after spring sowing in the next year,Shitianbu is sprayed once where has much weeds,and Lebang once when the first fading appears.In common fields Yicaoan will be sprayed once in spring,Lebang once in summer. ......
