由山东省药材公司等单位开展的栝楼主要病虫害防治及高产栽培技术的研究工作,经三年的努力,于1988年12月8日通过了省级技术鉴定。这一项研究成果首次明确了黑足黑守瓜和南方根结线虫为害栝楼,是导致栝楼减产的关键因素,搞清了这两种病虫的主要生物特性和发生规律等;研究选出了高效、低毒、低残留的农药 By Shandong Province herbs companies and other units to carry out the main Pest Control and high-yielding cultivation technology research work, after three years of efforts, on December 8, 1988 passed the provincial technical appraisal. The results of this study made it clear for the first time that the black-footed black-bellied melon and the southern root-knot nematode were the key factors that led to the decrease of the yield of the bream floor.
