| 中文摘要: |
| 溃疡病是火龙果种植上的重要病害。为掌握火龙果溃疡病在贵州火龙果主产区的发生情况和发病因素，为田间防控提供科学依据，特开展此调查研究。结果表明：罗甸、镇宁、关岭、望谟及贞丰5个主产县火龙果溃疡病均有不同程度发生，且主栽品种均可发病，各树龄果园均可发病。病害在冬季发生不明显，3月气温回升后病害开始陆续发生和扩展，4月上旬（清明前后）雨水较多病情迅速增长，是春季防控的关键时期。5~7月进入雨季，田间高温高湿，为病害大面积蔓延流行期，需及时做好田间防控，以保证火龙果安全生产。 |
| 英文摘要: |
| Canker is an important disease on pitaya. In order to understand the occurrence and factors associated with Pitaya canker in Guizhou pitaya main producing areas and provide scientific basis for field control, this investigation was carried out. The results showed that it occurred in different degrees in Luodian, Zhenning, Guanling, Wangmo and Zhenfeng counties, and the main varieties and orchards of all ages could be infected. The occurrence of the disease was not obvious in winter. After the temperature rose in March, the disease began to occur and expand. There was more rain in early April (around the Qingming Festival), the disease increased rapidly, which was the key period for prevention and control in spring. From May to July, the rainy season comes, with high temperature and high humidity in the field, which is the epidemic period of the disease spreading in large area. It is necessary to do a good job in field prevention and control in time to ensure the safety production of Pitaya. |
