| 摘 要： | 芒果炭疽病是海南省芒果生产中危害最严重的病害。本文应用生态位理论，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：0.950 8、0.941 2、0.965 3、0.849 7。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

| 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 environment. The indexes of habitat niche breadth of mango anthracnose were 0.9508 at the fruit stage, 0.9412 at summer shoot stage, 0.9653 at autumn shoot stage and 0.8497 at florescence stage. Mango anthracnose varied in its possession and use of spatial resource at different spatial niches. The spatial niches in the north side of the mango trees were unfavorable for the growth of the mango anthracnose. At florescence stage, spatial niches differed most greatly in orientations of the mango trees in the orchard, which produced significantly different effect on the habitat niche breadth of mango anthracnose. |
