摘要
宣城市位于皖南山区,自然生态环境优良。为进一步明确烟-稻轮作模式下稻鸭共育的相关问题,特开展了试验研究。结果表明:稻鸭农作系统下的稻田纹枯病的发生程度较低,一定程度上降低了二化螟等虫害的发生程度。与不养鸭对照相比,稻鸭共育后50d,二化螟枯心率降低了12%,放养密度180/hm^2较为合适。
Xuancheng City is in south of Anhui,has excellent natural ecological environment.To further define the tobacco-rice rotation mode,the issues related to rice-duck farming,carry out this study.The results showed that：the degree of rice sheath blight of rice-duck farming system was low and the occurrence of striped rice borer and others pests were reduced to a certain extent.Compared with the control without duck,after 50 d,dead heart rate caused by dry borer decreased by 12%,stocking density of 180/hm^2 was appropriate.
