1985～1989年对红星苹果树生产性能进行了研究。结果表明,红星苹果座果率较低的主要原因是花器结构特殊造成的,不利于授粉受精过程的进行,败育花率高。其次才是花期营养。同时表明,红星苹果花期要求温度较高,低温严重影响座果。红星苹果在盛果期的合理负载量应控制在每平方厘米干径0.30～0.35公斤时大小年幅度小,果实品质好。
From 1985 to 1989, the production performance of Red Star apple tree was studied. The results showed that the main reason for the low fruit rate of Red Star apple was the special structure of flower arrangement, which was not conducive to the pollination and fertilization process. Second is the flowering nutrition. At the same time, it indicates that the flowering period of Red Star apple requires higher temperature and the low temperature severely affects the fruit. Red Star Apple fruit in the full load reasonable period should be controlled at 0.30 ~ 0.35 kg per square centimeter dry size size of small amplitude, good fruit quality.
