控制柑桔的着花与结果,进行有效的果实生产,自古以来是生产者盼望的技术。柑桔的着花性与结果性视品种而异。着花过多的品种为了防止树体营养的消耗,谋求疏花技术,如极早生温州蜜柑和伊予柑为了限制着花防止树势衰退而喷布赤霉素;而隔年结果性强的品种和脐橙等结果性能差的品种,正在探求稳产的栽培技术。多年来,关于影响柑桔着花性、结果性因子的研究很多,特别是C/N比率。近年来,关于光合作用产物(糖)及其贮存形态(淀粉)含量与着花结果的关系研 Controlling the flowering and fruiting of citrus fruits for effective fruit production has long been a technology that producers hope for. Citrus flowers and fruiting vary depending on the species. To spend too much variety In order to prevent the depletion of tree nutrition, seeking to flower techniques, such as very early mandarin and Citrus to give priority to limit the flowers in order to prevent the recession and the gibberellin spray; and strong results of the species and Navel orange and other poor performance of the species, is seeking stable production techniques. Over the years, there have been many studies on the floristic and fruiting factors affecting citrus fruit, especially the C / N ratio. In recent years, the relationship between photosynthesis products (sugar) and its storage form (starch) content and the results of flowers
