为明确辽宁地区花生褐斑病发生危害及流行规律,以期指导病害防治,采用五点取样法,对辽宁省不同产区及不同品种花生褐斑病进行调查。2011年和2012年系统调查结果表明:不同产区病害均有发生,沈阳产区病害发生严重,兴城地区病害发生较轻,且多数产区2012年病情指数高于2011年。不同品种间病情指数也存在较大差异,其中四粒红最重,白花生最轻。通过SAS软件分析表明,Logistic模型能够较好地描述花生褐斑病病情指数随时间流行动态。
為明確遼寧地區花生褐斑病髮生危害及流行規律,以期指導病害防治,採用五點取樣法,對遼寧省不同產區及不同品種花生褐斑病進行調查。2011年和2012年繫統調查結果錶明:不同產區病害均有髮生,瀋暘產區病害髮生嚴重,興城地區病害髮生較輕,且多數產區2012年病情指數高于2011年。不同品種間病情指數也存在較大差異,其中四粒紅最重,白花生最輕。通過SAS軟件分析錶明,Logistic模型能夠較好地描述花生褐斑病病情指數隨時間流行動態。

To guide the control of peanut early leaf spot in fields,the disease damage and the epidemic dynam-ics were studied.The different region and different varieties of peanut leaf spot in Liaoning Province was investiga-ted by the method of five point sampling.A systematical investigation on the disease was carried out in 201 1 and 2012.The results showed that the diseases have occurred in different peanut production areas.Shenyang was the worst infected area and Xingcheng area was less infected.The disease index in 2012 was higher than in 201 1 in most areas.Different varieties had different disease index,the highest disease index was Silihong,the least disease index was Baihuasheng.Through comparing and analyzing,Logistic model could reflect the temporal dynamic of peanut early leaf spot disease well.
