我们于1970年春,从中国农科院柑桔研究所引入5个温州蜜柑品系(龟井、宫川、尾张、伊木力,池田),为一年生枳砧苗,苗床假植二年,1972年春定植。1972年秋又引入11个品系(松山、立间、兴津、米泽、上田、向山、林、南柑4号、南柑20号、石川、伴野),1974年春定植。株行距均为2×2.5公尺。经过10多年来的栽培认为,早、中熟各品系,都能在上海地区栽培。现将观察资料小结于后。一、种植情况(一)温州蜜柑在上海地区栽培,一般于4月上旬开始萌芽,4月下旬抽生春梢,5月 In the spring of 1970, we introduced five varieties of Satsuma mandarin (Kamei, Miyagawa, Matsusaka, Iwaki, Ikeda) from the Citrus Institute of Chinese Academy of Agricultural Sciences for the annual tree seedlings, Colonization. In the autumn of 1972, 11 strains were introduced (Matsuyama, Risan, Xingjin, Yonezawa, Ueda, Xiangshan, Lin, Nangan No. 4, Nangan No. 20, Ishikawa, Line spacing are 2 × 2.5 meters. After more than 10 years of cultivation that early, middle-maturity of the strains, can be cultivated in Shanghai. Now observe the data summary in the post. First, the planting situation (a) Wenzhou Satsuma cultivation in Shanghai, usually in early April germination, spring pumping spring in late April, May
