- 摘要:
- 为了明确大豆蚜对大豆危害的作用机理,研究了大豆蚜阶段性危害对大豆产量及其相关性状的影响。结果表明:随着大豆蚜危害时期的延长,大豆蚜对大豆产量及其它性状的影响作用越强。在短期危害的条件下,对大豆株高的影响显著,但产量几乎不受影响。当危害达到大豆的盛花期,产量开始下降,危害达到结荚期时产量显著降低。因此,在大豆的盛花期之前防治大豆蚜会有效减少产量损失。
- Abstract:
- In order to determine the damage mechanism of soybean aphid on soybean,the effect of periodic damage effect on soybean yield and its related factors were studied.The results showed that effects were more significant with the extension of aphid infested time on soybean.The effect on plant height were singnificant difference after shortterm infested,and there was no difference on yield.The infested of aphid at the stage of full bloom caused the decline of soybean yield,soybean yield was significantly decreased at stage of pod formation.Therefore,it could decrease the yield loss to control before the stage of full bloom effectively.
