由河北省农林科学院植物保护研究所完成的《河北省甘薯茎线虫病病原线虫鉴定及防治新技术》近日通过专家鉴定,认为该项研究的水平居国内领先。甘薯茎线虫病是生产上很难防治的病害。传统的防治方法,一是清洁田园;二是实行三年轮作;三是高剪秧苗繁殖无病种薯。这套措施虽然有效,但难于贯彻实施,造成本病随病薯秧传播危害逐年加重,有的地块减产50％以上,严重影响了甘薯生产的发展。
Hebei Province, Academy of Agriculture and Forestry Institute of Plant Protection completed the “Hebei Province Sweet Potato Stem nematode pathogen identification and prevention and treatment of nematodes new technology” recently passed the expert assessment, that the level of the study Habitat leading domestic. Sweet potato stem nematode disease is difficult to control the production of disease. Traditional methods of prevention and treatment, first, clean the garden; Second, the implementation of three-wheeled crop rotation; Third, high-shear seedling breeding disease-free seed tubers. Although this set of measures is effective, but difficult to implement, resulting in the disease with the proliferation of disease potato seedlings increased year by year, some plots yield reduction of more than 50%, seriously affected the development of sweet potato production.
