我省现有果树七十五万余株,其中苹果、梨、李、杏等树种中,属于高产优质的约占70%左右。各树种中都存在不同程度的低产劣质品种,甚至有的地区和果园低劣品种所占比例较大,不仅果实品质差,产量低,而且影响果园的经济收入。如:73年调查牡丹江郊区二十九万株苹果中,低产劣质树占六万株,桦林公社工农大队二万株果树中,有低产劣质树五千多株,宾县宾西果树场一万一千株结果树中,有四千多株低劣品种。还有的果园单栽大秋,虽然品种较好,但缺少合理的授粉品种,也得不到产量或产量很低。
There are more than 750,000 existing fruit trees in our province, among which about 70% belong to high yielding and high quality among the apple, pear, plum and apricot tree species. There are varying degrees of low-yielding and poor-quality varieties in all tree species, and even some regions and orchards have a large proportion of inferior varieties, which not only have poor fruit quality and low yield, but also affect the economic income of orchards. Such as: 73 years survey of 290,000 suburbs of Mudanjiang apples, low-yield inferior tree accounts for 60,000, birch commune brigade 20,000 trees, low-yield inferior tree more than 5000 strains of Bingxian Bingxi fruit tree field Thousands of trees in the results, there are more than 4,000 poor varieties. There are large orchard single autumn planting, although the variety is better, but the lack of a reasonable variety of pollination, also can not get the output or yield is very low.
