【摘要】 富士苹果在黄河故道地区生长旺盛,树体健壮,树冠扩展较快,新梢年生长量达1米左右。萌芽率和发枝力较强。乔砧根系分布的密集层在20～60厘米。4～5年生开始结果。初期以长果枝结果为主,并有相当数量的腋花芽,以后随树龄逐渐过渡到以短果枝结果为主。连续结果能力弱。座果率高,不疏果易引起大小年结果。自交结实率低,杂交结实率以国光、红星、胜利等品种最高。通常富士的花芽萌动和盛花期分别为3月中旬和4月中旬,果实10月上旬成熟,落叶期11月底。对早期落叶病和炭疽病抗性较强,裂果轻。轮纹病和腐烂病较重,必须加强防治。总之,富士对黄河故道气候土壤具有良好的适应性。更多还原

【Abstract】 Biological characteristics of cv. Fuji apple were observed systematically in Dashahe Orchard, Fengxian, Jiangsu, from 1977 to 1982. The results indicate that Fuji is well adapted to the climate and soil of the Old Yellow River Basin Area. The phenological phases of Fuji in this area are flower bud breaking in mid-March, full bloom in mid-April, fruit mature early in October, and leaf-fall in late November, periods of tree growth and fruit development being about 250 days and 175 days, respectively. Fuji is characterized by more vigorous tree growth and quick formation of tree crown, and higher rates of off-bud and long shoot. Fuji has about 69.9% of total roots distributing in the depth of 20-60 cm, some rooting into more than 1 minsandy soil.Fuji begins bearing early,mainly on long shoots and in axillary in early stage, and bearing points shift to middle and short shoots with growing age. Fuji has the advantages of higher fruit set rate and production, lower fruit-split rate, better quality and storage life of fruit. Dilicious, Golden Dilieious, Fushuai, Shengli, Kuihua and Liaofu can serve as its pollen parents. Fuji is resistant to Glomerella cingulata (Stonem.) Schr. et Spauld. and Marssonina coronaria (E11.et Davis) Davis, however, less to Physalospora piricola Nose and Valsa mali Miyabe et Yamada.更多还原
