摘  要：
以循化红线辣椒为研究对象,结合不同栽培地特点和降雨量因素研究了2009—2014年6年间循化县线辣椒疫病多发区积石镇和查汗都斯乡各地发病率。结果表明:沙壤地、半阴半阳地、阴湿地及积水地平均发病率分别为4.54%、6.87%、10.63%和20.69%;连作年限1~4年的地块的平均发病率分别为2.61%、5.03%、17.05%和26.34%;从2009—2014年,循化积石镇新建村地块发病率分别为0、10.60%、2.25%、18.30%、7.70%和12.55%。表明沙壤地发生最轻,其次为半阴半阳地,再是阴湿地,积水地发病最重,同时种植地连作时间越长,发病越严重,6月降雨量大,也有利于疫病发生。该结果将为循化红线辣椒疫病的防治提供理论参考。

摘  要：
To research on the occurrence conditions of Xunhua line chilli phytophthora in different cultivated fields types and precipitation was combined to study Xunhua line chilli phytophthora morbidity in Jishi and Chahandousi where were pepper phytophthora prevalent area,during 2009—2014.The results showed that the average morbidity of sand soil fields,half shady half sunlit fields,shady wet field,and soaked field were 4.54%,6.87%,10.63% and 20.69%,respectively;the average morbidity of continuous cropping fields continuous cropping for 1-4years were 2.61%,5.03%,17.05%,and 26.34%,respectively;the average morbidity of Xinjian village,Jishi,from 2009 to 2014,were 0,10.60%,2.25%,18.30%,7.70% and 12.55%,respectively.The results also indicated that sand soil fields showed the lightest morbidity,followed by half shady half sunlit fields,then,shady wet field,soaked field got the highest morbidity,at the same time,the longer continuous cropping year field,the more seriously the disease occurrence,high precipitation in June was helpful for pepper phytophthora occurrence.All these results provided a theoretical reference for Xunhua line chilli phytophthora preventing and controlling.
