气象条件对柑桔树生长和结果的影响

EFFECTS OF METEOROLOGICAL CONDITION ON GROWTH AND FRUIT BEARING OF CITRUS TREE

本文分析了1988年相1989年气象条件对柑桔树主要物候期、早春叶片光合作用能力、树体营养生长和生殖生长、以及果实产量和品质的影响,探讨了减轻异常气象条件的影响,争取柑桔高产、稳产、优质的栽培途径。 八十年代,我国柑桔产区受异常气象条件影响,发生三次大面积的异常生理落果,当年减产50～80％,导致大小年结果,引起普遍关注[1—4]。这种现象在国外也有发生,对其解释众说纷纭[5—8],亟待深入研究。本文通过分析1998年(小年结果)和1989年(大年结果)主要气象条件差异及其对柑桔树生长和结果的影响,为生产中合理决策、减轻异常气象条件的影响提供科学依据。

In this paper, effects of meteorological condition on mainly phenological Phases, leaf photosynthetic capacity, vegetative growth and reproductive growth, fruit yield and its quality of citrus tree in 1988 and 1989 were analysed, respec-ively. Some countermeasures how to reduce bad influence of abnormal meteorological condition to get higher yield and superior quality of fruits in citriculture were also discussed.
