近几年来,西林沙糖橘虽然有了规模化发展,逐步形成了地方有名的产业,但产量和质量都徘徊在起步阶段中,尤其是产量低质量差是制约西林沙糖橘产业提升的主要因素,为此,提出相应对策,以提高产量质量为重点,发挥合作社的作用,出台优惠政策,增加产品流通渠道,加快沙糖橘的流通,维护西林沙糖橘价格的相对稳定,增加果农的收入。 相似文献

华丰甜橘(Citrus reticulata Blanco ‘Huafengtianju’)是从贡柑、椪柑、甜橙和沙糖橘混种果园中收集的沙糖橘果实种子,后经实生选种获得的新品种。该品种树势强健,枝条萌芽率和成枝力均强于对照沙糖橘,易成花坐果。果实为扁球形,果个比对照大,平均单果质量70.4 g,约是对照的1.4倍;果皮厚度约为2.0 mm,易剥皮,完熟果实的果面为橙黄色、平滑、有光泽。果瓣易分离,果肉橙色,化渣,无籽,风味清甜有芳香味,可溶性固形物含量(w,后同)为10.4%～11.0%,总糖含量为7.9%～8.1%,可滴定酸含量为0.25%～0.29%,维生素C含量(ρ)为14.3～15.7 mg·100 mL-1。果实成熟期为12月中旬到翌年1月上旬,与对照基本相同。盛果期的产量可达53 100 kg·hm-2,比对照增产约15%。SSR分子标记遗传鉴定结果显示,华丰甜橘与对照沙糖橘在基因组水平上存在明显差异,是一个遗传稳定的柑橘新品种。 相似文献

近年在沙糖橘主要产区广东省肇庆市和云浮市,沙糖橘囚黄化而导致低产、果实品质下降、树体早衰甚至死亡的现象剧增。试验处理800株沙糖橘,死亡16株,死亡率2％;对照120株,死亡91株,死亡率75．8％。研究表明：根据沙糖橘生物学特性和年生长发育规律,通过科学管理增强树势,能够减少沙糖橘黄化死亡,延长树体寿命。 相似文献

The anatomy of the fruit has been compared in three prone-to-split mandarin hybrids (Nova, Ellendale and Murcott), several cultivars of clementine mandarin (Fino, Clementina de Nules and Orogrande), and in Owari satsuma mandarin. The fruit of the hybrids is oblate to subglobose and usually presents an open stylar end disrupted by a navel formed by the floral meristem, which is conserved near the apex of the fruit. In the non-prone-to-split clementines as well as in Owari satsuma, the floral axis protrudes inside the style, and the flower meristem is lost through abscission shortly after petal fall. The abaxial side of the carpels fuses with the flower axis forming at the stylar end of the fruit a solid tissue which externally has a small scar at the place of style abscission. Most of the fruits in these cultivars have no navel. In addition, the fruit of clementine is slightly oblate or globose. The relevance of these anatomical characteristics as regards to splitting is supported by the differences between the split and non-split fruits in Nova, the split fruit being more oblate in shape and having a bigger navel than non-split fruit. However, the effect of applied growth regulators on fruit splitting could not be correlated with their effect on the anatomy of the fruit. Additional factors not contemplated in the study also influence fruit splitting. 相似文献
