| 摘 要： | 以辽豆15为材料,采用人工接种的方法,分别测定了不同酸类化合物对大豆胞囊线虫的温室防治效果和对大豆植株生长情况的影响。结果表明:供试化合物中,甲酸和丙酸对大豆胞囊线虫的抑制率相对较高,对线虫的温室防治效果最好;乙酸和乙二酸次之;柠檬酸和苹果酸对线虫的防效较低。乙二酸、柠檬酸和苹果酸对大豆植株的生长抑制作用较小。综合试验结果,确定乙二酸是较为理想的线虫防治药剂。

| Abstract: | In order to clarify the effect of acid compound on soybean cyst nematode and host growth,soybean cultivar Liaodou 15 was pot planted in greenhouse and when the first true leaves were expanded,each soybean plant were inoculated with 2 000 eggs of SCN combined with 10 mL different acid compounds into the soil.Amount of cysts,plant height,shoot fresh weight and root fresh weight were detected 35 days after emergence.Among the 6 acid compounds,nematode suppression rate of Formic and Propionic acid were the highest;followed by Acetic acid and Oxalic acid;Citric acid and Malic acid were the lowest.Oxalic acid,Citric acid and Malic acid had lower inhibition effect on plant traits considering plant height,shoot fresh weight and root fresh weight.Results suggest Oxalic acid is an ideal nematode control agent for soybean. |
