在氟污染严重地区，香蕉采用适时套袋，增施钙、镁、硼肥，在把头前和抽蕾、断蕾套袋前后喷３次防氟药剂，能增加叶片叶绿素含量，提高叶片净光合速率和单株产量。经防氟处理的香蕉防腐或防腐保鲜后能明显地提高香蕉品质和耐藏性，催熟后果皮均匀黄熟，肉质结实、香甜，可溶性固形物提高３．４—４．０个百分点，明显地改善了商品外观品质和食用品质。 In areas with serious fluorine pollution, bananas should be bagged at the right time and calcium, magnesium and boron fertilizers should be added. Before spraying the buds and leaning buds, the bananas should be sprayed three times before and after the spraying, so that the chlorophyll content could be increased and the net photosynthesis of the leaves increased Rate and yield per plant. The anti-fluoride treated banana preservative or preservative can obviously improve the quality and storability of bananas. After ripening, the pericarp is evenly yellowed, the meat is firm, sweet and soluble solids increase by 3.4-4.0 percentage points, obviously Improve the appearance of goods and food quality.
