| 为了掌握2012年广西南宁和百色地区芒果日灼病的发生受害情况，于4月29日、5月2日、5月8-11日和5月15-18日在南宁市、百色市右江区、田林县、田东县和西林县选择有代表性的果园，调查不同芒果品种幼果日灼病的受害率。调查结果表明：（1）南宁地区未发现果实受日灼病危害；右江河谷地区日灼病发生较为普遍，田东县、田林县、西林县、右江区和广西农垦国有阳圩农场的芒果日灼病受害率分别为22.2%、20.3%、22.8%、19.6%和20.4%。（2）不同品种受害率不同。‘台农1号芒’受害率最低，为12.0%；‘红贵妃’、‘桂热芒82号’和‘桂热芒71号’受害率较高，分别达到31.3%、29.6%和27.5%。针对春末夏初芒果幼果易遭高温日灼的问题，提出了果园灌水、生草、播种绿肥等降低日灼病发生的预防措施。 |
