| 中文摘要: |
| 在广东省广州市花都区和白云区系统调查了稻菜轮作田、水稻连作田的水稻害虫褐飞虱 Nilaparvata lugens (Stal)及其捕食性天敌蜘蛛的数量，结果表明：与水稻连作相比，花都区稻菜轮作模式总体上降低了褐飞虱数量，同期最高降低66.6%，对田间蜘蛛数量影响不明显；白云区的稻菜轮作模式也显著降低了褐飞虱的数量，同期最高降低56.3%，对蜘蛛数量的影响也不明显。稻菜轮作模式能有效降低田间褐飞虱数量，有利于水稻生产。 |
| 英文摘要: |
| The density of the brown planthopper (BPH) Nilaparvata lugens (Stal) and spiders was investigated in two farming patterns: rice-vegetable rotation and rice continuous cropping, in the paddy fields of Huadu and Baiyun district of Guangzhou City. The results showed that in Huadu district, rice-vegetable rotation often reduced BPH density in paddy fields, up to 66.6% reduction compared to the control (rice continuous cropping), but the effect on the density of spiders was not obvious; in Baiyun district, rice-vegetable rotation significantly decreased BPH density, up to 56.30% reduction compared to the control, the density of spiders did not change obviously. Our investigation suggests that rice-vegetable rotation effectively reduce BPH density in paddy fields, and is beneficial to rice production. |
