广梨属秋子梨系,原产廊坊市万庄一带。现主要分布在永定河周围风沙地带。广梨树势强健,适应性广,抗逆性强,耐旱耐涝耐瘠薄。现廊坊市栽培面积达4000公顷,产量3000万公斤,主要销往东北三省及京、津、唐果品市场。但近几年外销逐年减少,卖果难问题越来越突出,极大影响了广梨生产的发展。一、廊坊市广梨生产中存在的主要问题 1、品种退化严重,株间差异大。由于缺乏规范化的栽培管理和选优,育苗时盲目采集接穗,造成广梨良莠不齐,品种退化,劣质果较多,即使在同一果园内果实大小、外观、整齐度品质也相差较大。
Pear is a sub-pear line, native of Langfang City, Wan Zhuang area. Now mainly distributed in the sand area around the Yongding River. Canton pear strong potential, wide adaptability, strong resistance, drought tolerance drought. Now Langfang cultivation area of 4000 hectares, output 30 million kilograms, mainly exported to the three northeastern provinces and Beijing, Tianjin, Tang fruit market. However, in recent years, export decreased year by year, the problem of selling fruit is more and more prominent, which greatly affected the development of Guangzhou pear production. First, the main problems in Guang-li production in Langfang City 1, the serious degeneration of varieties, large differences between strains. Due to the lack of standardized cultivation management and selection, the scion was blindly collected during seedling raising, resulting in the mixed varieties of Guangli. The varieties degenerated and inferior fruits were more. Even though the fruit size, appearance and uniformity in the same orchard varied greatly.
