线虫的防治 农业措施 防治线虫要特别注意采用一种或多种防治措施,以防止线虫群体数量增长到或超过危害水准。防治战略中必须考虑的重要因素应包括线虫的生物学和生态学特性之间的相互联系、病原线虫的传播途径、每公顷寄主作物的生产价值以及可用于特定地域的栽培(防治)措施。 作物轮作是最古老的也是最广泛应用于大田防治线虫的措施。仅仅根据作物产量效果而未考虑线虫问题的轮栽,常常将增产归诸于无意中防
Prevention and control of nematodes Agricultural measures Prevention and control of nematodes Special attention should be given to the use of one or more control measures to prevent the population of nematodes from increasing or exceeding the hazard level. Important factors that must be considered in a control strategy should include the interlinkages between the biological and ecological characteristics of nematodes, the pathogen transmission of pathogenic nematodes, the production value of host crops per hectare, and cultivation (control) measures that can be used in a particular area. Crop rotation is the oldest and most widely used measure for controlling nematodes in the field. Rotations, which are based on crop yield effects without regard to nematode problems, often attribute increases to unintentional
