[目的]探讨温度和湿度对胡椒生长特性及发病率的影响.[方法]于2011年3月至2012年2月在云南保山潞江坝胡椒试验示范基地研究了大气温度和湿度对胡椒生长量及主要病害发病率的影响.[结果]在5 ～10月温湿度绝对值相对大时,胡椒生长变化量较大,且在这高温高湿的月份胡椒细菌性叶斑病、叶斑病、藻斑病及炭疽病发生也较严重,发病率最高分别达44.0％、46.4％、17.7％和25.5％;在11月至次年2月温湿度绝对值相对小时,胡椒生长变化量较小,且在这低温低湿的月份胡椒细菌性叶斑病、叶斑病、藻斑病及炭疽病发病程度也较小,发病率分别达4.0％、9.5％、0.7％和6.3％.[结论]温度和湿度均对胡椒生长特性及发病率有一定影响.%[ Objective ] The aim was to study effects of temperature and humidity on the growth and incidence of pepper. [ Method ] Effects of temperature and humidity on the growth and incidence of pepper were studied in Lujiangba test demonstration base of Yunnan Province from March, 2011 to February, 2012. [Result] When the absolute values of temperature and humidity were relatively large form May to October, the growth of pepper changed greatly, furthermore bacterial leaf spot, leaf spot, algal spot disease and anthrax of pepper were also serious, respectively with the highest incidences of 44. 0% , 46. 4% , 17. 7% and 25.5% . When the absolute values of temperature and humidity were relatively small from Remember to February of next year, the growth of pepper had small change, furthermore bacterial leaf spot, leaf spot, algal spot disease and anthrax of pepper were also slight, respectively with the incidences of 4.0% , 9.5% , 0.7% and 6.3%. [Conclusion] Temperature and humidity has certain effects on the growth characteristics of pepper and the incidence of a disease.
