摘　　要：开展了稻鸭共育和稻鱼共育结合灯光诱杀防治有机稻田主要病虫害的研究。结果表明,在4个处理中,灯光诱杀+稻鸭共育对水稻病虫的防效最好,对黑尾叶蝉、稻飞虱、四点叶蝉、水稻枯心白穗的相对防效分别高达80.82%、77.16%、74.13%和59.83%;灯光诱杀+稻鸭共育处理田水稻纹枯病和水稻条纹叶枯病的田间发病率显著低于对照田,相对防效分别达85.38%和70.37%;稻鱼共育、灯光诱杀+稻鱼共育、稻鸭共育、灯光诱杀+稻鸭共育处理的稻田总利润较对照田分别增加了5.95万、5.86万、5.47万和5.31万元/hm 2。可见稻田养殖结合灯光诱杀在提升有机稻田主要病虫害防效的同时能稳定增产创收。The control effect of rice-fish farming and rice-duck farming combined with light trapping on main diseases and pests in organic rice was studied.The results showed that the insecticidal lamp combined with rice-duck breeding(light trapping+rice-duck)had the best control effect on rice diseases and insect pests among the four treatments.The relative control effect of Light trapping+rice-duck on Nephotettix cincticeps,rice planthopper,Cicadula masatonis,rice dead heart and white head were 80.81%,77.15%,74.13%and 59.94%respectively.The field incidence rates of rice sheath blight and rice stripe disease in light trapping+rice-duck fields were significantly lower than those in the control field,and the relative control effect was 85.38%and 70.37%,respectively.Compared with the control field,the total profits of 4 treatment groups of rice-fish breeding,light trapping+rice-fish,rice-duck breeding and light trapping+rice-duck,were increased by 59500,58600,54700 and 53100 yuan/hm 2,respectively.Therefore,paddy field culture combined with light trapping can improve the control effect of main diseases and insect pests in organic paddy field,and increase production and income steadily.
