利用成年甜橙、柚结果树的枝段露地扦插繁殖,生根、成活较困难。用无土育苗,一个月后便开始生根,70天后锦橙生根成活率86％,5个月后可达95％。对保持柑桔种质、快速繁育纯系良种、缩短育苗时间等具有重要意义。 (一)选用介质:柑桔无土育苗包括气培、水培、沙培、蛭石培、珍珠岩培等多种方式,以珍珠岩、蛭石作介质效果最好。5号蛭石(四川彭县蒙阳镇蛭石厂生产)具有质轻(150—180公斤/米~3)、保湿(含水 The use of adult sweet orange, pomelo tree branches exposed branches cuttings, rooting, survival more difficult. With soilless seedlings, one month after they began to root, 70 days after the survival rate of 86% Jincheng orange, 5 months up to 95%. To maintain citrus germplasm, rapid breeding purebred varieties, shorten the time of raising seedlings is of great significance. (A) the choice of medium: Citrus soilless culture, including gas culture, hydroponics, sand culture, vermiculite culture, perlite culture and other means to perlite, vermiculite as the best media. Vermiculite No. 5 (Mengyang Town, Peng County, Sichuan Province vermiculite plant production) with light (150-180 kg / m ~ 3), moisturizing (water
