摘要
大豆孢囊线虫在襄汾县一般1a发生4代。该线虫主要分布在15cm以内的耕作层,降雨对它的垂直分布影响较大,雨后线虫下移。受害程度不受播期影响。不同的大豆品种对线虫有抗性差异。田间药剂试验表明,5%涕灭威颗粒剂土施防效最好,表现出明显的增产作用。
Heterodera glycines Ichinohe annually occurred four generations in Xiangfen county. The nematodes mainly distributed in the upper cultivated soil with deepness less than 15 cm. Precipitation affected its vertical distribution, the nematodes moved deeper after raining. The damage degree was not affected by sowing time. Different soybean varieties presented different disease resistance. The experiment in the field showed that good control effects could be made by soil treatments by using 5% (ai) Temik granulates, and the soybean yields were increased obviously.
