随着我省保护地设施蔬菜面积的扩大,多年连作,过量施用化肥,导致土壤酸化和以根结线虫病为代表的土传病害日趋严重,成为实现日光温室等设施蔬菜产品安全生产和可持续发展的重大限制因素。根据省农业厅领导的指示,蔬菜分团在寿光、苍山等设施蔬菜主产区开展了调查研究,并认真总结了“十五”国家和省无公害蔬菜生产关键技术研究中有关根结线虫病发生和防治研究的结果,现综合报告如下,供领导和各地参考。
With the expansion of vegetable area in protected areas in our province, continuous cropping and overuse of fertilizers over the years have led to soil acidification and soil-borne diseases such as root-knot nematode disease becoming more and more serious, and have become the safe production and sustainable development of vegetable products such as solar greenhouse Great constraints to development. According to the instructions of the leaders of Provincial Department of Agriculture, vegetable sub-groups conducted research in major vegetable producing areas such as Shouguang and Cangshan, and conscientiously summarized the root causes of key technologies in the “15” national and provincial pollution-free vegetable production The results of the study on the occurrence and prevention of nematode disease are summarized below and are for reference by leaders and other places.
