水稻牛蛙生态种养对稻飞虱防效及水稻产量的影响
Effects of Rice-Bullfrog Mixed Cultivation on Rice Planthoppers and Rice Yield
摘要
Abstract
The ecological effects of rice-bullfrog mixed cultivation were investigated in the demonstration base of high quality rice, Hunan in 2011. Results showed that planthopper population in paddy fields with 900 and 1500 bullfrog·hm−2 was decreased by 60%—70%, while spider and Cyrtorhinus lividipennis were not negatively affected. Seed-setting in paddy fields with 900 and 1500 bullfrog·hm−2 was increased by 13.8% and 15.8%, respectively, compared with the blank-control area, but was decreased by 6.2% and 4.1%, respectively, compared to chemical control fields. Rice yield was significantly higher in paddy fields with 900 and 1500 bullfrog·hm−2 than that in the blank-control fields, but was significantly lower in yields with 900 bullfrog·hm−2 than that in chemical control fields.关键词
