| 摘 要： | 应用生态位理论，测定芒果炭疽病生境生态位。结果表明，芒果炭疽病的空间生态位宽度指数比较大，对空间资源利用较充分。果园中间的果树通风性差，湿度大，芒果炭疽病的病情指数最大，北边边线较通风、湿度小，芒果炭疽病病情指数最小。果实期、夏稍期、秋稍期、花期芒果炭疽病的生境生态位宽度指数依次为：0．9508、0．9412、0．9653和0．8497。在各生境位点上，芒果炭疽病对资源的占有和利用能力是不同的，边线的生境相对不利于芒果炭疽病的生存，花期时果园各方位生境差异最大，对芒果炭疽病的生境生态位宽度影响最显著。 |

| Abstract: | Mango anthracnose is the most serious disease attacking mango in Hainan Province. The niche theory was used to determine the habitat niche of mango anthracnose. The spatial niche breadth of mango anthracnose was found to have a higher index, indicating a full use of spatial resource by the mango anthracnose. Disease index of mango anthracnose was maximum in the middle of orchard because of unventilated and humid environment, and minimum in the north of the mango orchard due to its dry and ventilated environ... |
