永春县椪柑栽培面积已近6666hm~2,所用砧木为枳和红桔(福桔)。为从两者中确定最适合红壤山地椪柑栽培的砧木,笔者近年来进行了观察和研究。 供试树1982～1983年定植,所在园址海拔240～260m,坡度30°。据1988～1990年观察,枳砧椪柑砧木部分比接穗部分明显膨大,嫁接口有明显界线;红桔砧椪柑嫁接口光滑,无明显界线。主干周长
Yongchun County citrus cultivation area of nearly 6666hm ~ 2, the rootstock used for the trifoliate orange and red orange (bilberry). In order to determine the most suitable rootstocks cultivated in red soil mountain citrus, the author has observed and studied in recent years. The test trees were planted from 1982 to 1983, where the site of the park was 240 ~ 260m above sea level with a slope of 30 °. According to the observation from 1988 to 1990, the part of Poncirus angustifolia rootstock was obviously larger than that of the scion, and the grafting interface had a clear boundary; the citrus root of Citrus aurantium was smooth and had no obvious boundary. The trunk circumference
