| 中文摘要: |
| 福建省2011年翠冠梨由于开花期气温偏低、叶片早衰脱落严重、授粉品种搭配不当、辅助授粉措施不力、生理落果异常严重等原因，导致坐果率偏低，平均坐果率不及5%，最低的仅达0.8%，预计产量较常年减30%以上。立足长远，对此，提出相应的主要防治措施有示范推广避雨栽培、严防叶片早衰脱落、改善自然授粉条件、普及人工授粉技术、防止大量生理落果等，以图根本上加于解决。 |
| 英文摘要: |
| Fruit-setting rate low of ‘Cuiguan’ Pear happens widely in Fujian province in 2011 and results in yield reduction by more than 30%. The main reason of fruit-setting rate low was low temperatures in flowering, presenility pathogenesis, mismatching pollination varieties, subsidiary pollination inadequate measures and very serious physiological fruit drop, etc. A long-term, which put forward the corresponding main control measures, mainly includes rain shelter cultivation, preventing premature leaf loss, improving the natural pollination conditions, Popularizing of artificial pollination techniques and preventing a large number of physiological fruit drop, etc. |
