| 中文摘要: |
| 为了探究基于栽培与耕作措施的稻飞虱防治新技术，降低农业生产的植保成本投入。以4个稻飞虱抗性级别的中稻品种（玮两优7713（3级）、华两优10（5级）、F优498（9级）、徽两优粤农丝苗（9级））为材料，研究了不同抗性级别水稻品种穿插“回”形布局对稻飞虱的防治效果。穿插“回”形布局处理全生育期稻飞虱相对发生率约为70%~97%，与常规布局相比，未施药处理下穿插“回”形布局处理水稻产量提高2.10%~4.28%，抗性级别越低增产幅度越大；穿插“回”形布局条件下，与施药处理对比，未施药处理水稻减产2.31%~6.11%，抗性级别越低减产幅度越大，可见穿插“回”形布局配合适当的药剂防治的防治效果更好。以不同稻飞虱抗性水稻品种实行穿插“回”形布局可在一定程度上减轻稻飞虱危害，降低产量损失，但具体效果与品种的抗性级别有关，外围品种的抗性级别越高、中心品种的抗性级别越低，就越能够体现穿插“回”形布局栽培模式的优势。 |

| In order to explore the new technology of rice planthopper control based on cultivation and tillage measures and reduce the input of plant protection cost in agricultural production. Four rice varieties with different resistance levels (Weiliangyou 7713 (Level 3), Hualiangyou 10 (Level 5), Fyou 498 (Level 9), Huiliangyou Yuenongsimiao (Level 9) ) were used as materials to study the control effect of rice varieties with different resistance levels on rice planthopper by interspersing a layout resembling 回(a Chinese character) and low toxicity pesticide control. The relative incidence of rice planthoppers in the whole growth period of the interspersed a layout resembling 回(a Chinese character) was about 70%~97%. Compared with the conventional layout, the yield of rice was increased by 2.10%~4.28% under the condition of no pesticide application, and the lower the resistance level, the greater the yield increase. Under the condition of interspersed a layout resembling 回(a Chinese character), compared with spraying treatment, the yield of rice without spraying treatment decreased by 2.31%~6.11%. The lower the resistance level, the greater the yield reduction. It can be seen that the interspersed a layout resembling 回(a Chinese character) combined with appropriate pesticide control has better control effect. The interspersed interspersed of rice varieties with different resistance to rice planthoppers can reduce the harm of rice planthoppers and reduce the yield loss to a certain extent, but the specific effect is related to the resistance level of the varieties. The higher the resistance level of the peripheral varieties and the lower the resistance level of the central varieties, the more the advantages of the interspersed a layout resembling 回(a Chinese character) cultivation mode can be reflected. |
