摘要
甜橙[Citrus sinensis(L.)Osbesk,本文中均指雪柑(Citrus sinensis var.sekkan)]对日照的需要量,比温州蜜柑(Citrus reticulata var.unshiu)等桔类要少些,即温州蜜柑比甜橙和杂柑类的耐荫性稍弱。然而,究竟可少到什么临界值呢?同一果园,同一管理水平,同一树龄,由于坡向、地形等的不同。
Cultivation of Citrus sinensis is wide-spread in various latitude areas in China. Eased on observation and researches, it is found that within the same plantation, under identical management levels and at same age, the growth and development of Citrus sinensis are influenced by the length of illumination period caused by site factor variation. The nutritional and reproductive growths of Citrus sinensis are most favorable at an average diurnal illumination period of above 9.5 hours, secondarily of 8 hours and most unfavorable of below 6-6.5 hours.
