黑龙江省西部地区大豆胞囊线虫病物理防治技术研究

Research on Physical Control Technology of Soybean Cyst Nematode in Western Region of Heilongjiang Province

为研究黑龙江省大豆胞囊线虫病的发生规律并探讨其防治技术,对不同品种、品种混播、不同耕作方式胞囊线虫病进行了田间鉴定。利用烘干称重法等对干物质积累、叶面积、单株胞囊数量和产量等方面进行调查。结果表明:选用抗线品种可有效地减少大豆植株根际胞囊的数量;品种混播对防治大豆胞囊线虫没有明显的效果;不同耕作方式中,原垄卡种产量高于其它方式。表明黑龙江省西部地区大豆胞囊线虫病可以通过应用抗线品种、不同耕作方式等防治措施进行有效控制,对进一步研究的方向进行了展望。

For researching occurrence rules and prevention technology of soybean cyst nematode（SCN）, field identification of different varieties,varieties mixture,different cultivation ways were researched. Main reason for SCN occurrence in Heilongjiang western region was put forward by researching dry matter accumulation,leaf area, cysts number and yield. The results showed that resistant varieties could effectively reduce the number of SCN ;varieties mixture had no obvious effect on the prevention and treatment of SCN;yield of original ridge till- age was higher than other methods. Hazard and control measures of SCN were proposed in western region of Heilongjiang and further research directions was prospected.
