摘要
本文测试了不同品种大豆叶片内氮素含量在大豆蚜(Aphis glycines Mutsumura)发生期间的变化趋势,找出了大豆蚜发生量与叶片氮素含量的相关关系。建议把豆株叶片内氮素含量作为大豆蚜发生量预测预报的生态因子之一。
In this experiment, the nitrogen contents in leaves of different types soybean were exam-inated during the sapsucking stage of Aphid. The relation between nitrogen content and aphid population was found. It was suggested that the nitrogen content in soybean leaves could be used as one of the biological factor of forecasting the population of aphid.
